29 A. Gain / Shutter Tab Figure 35: Gain/Shutter Tab in Advanced Settings 1. ALC Mode Selection: The following seven ALC (Automatic Light Compensation) modes are selectable through the drop down menu. As these various modes are selected the control options, on the control option screen, will change. Note: In the case that at least one of the auto modes is selected (b, c, and d below) it is possible that a constant flickering or brightness fluctuation may occur in environment s with fluorescent lighting. This is because the internal feedback time is too long for the photometric detection for the ALC function since this decision is executed on the computer over the USB port. a. OFF (ALC Fixed / AGC OFF) In this mode, the camera works with a fixed shutter speed and a fixed gain value. This mode is suitable for applications which have consistent light conditions or when absolute video level measurements are required. Since there is no automatic gain or shutter function in this setting, the picture may be too dark or saturated depending on the adjustments of the shutter speed, fixed gain and/or lens aperture. Adjust these three for optimum brightness of the image. The available control functions for this mode are: Gain Shutter Preset Shutter Speed Buttons b. ALC FullAuto/ AGC ON In this mode, the camera works in the auto shutter mode and AGC (automatic gain control). This mode is suitable for applications in which lighting conditions change gradually (i.e. applications with natural outdoor lighting). In this mode, the shutter speed and gain change automatically to maintain the video output level at optimum brightness, despite light intensity changed on the object. The Target Brightness slide bar is activated when this mode is selected and this Target Brightness level defines the targeted brightness level desired to be maintained automatically. The available control functions for this mode are: Weight Target Brightness Brightness Tolerance Brightness Threshold AGC Range Shutter Range Software Manual 25 of 41 Ver. 2.0

30 c. ALC FullAuto/ AGC OFF In this mode, the camera works with the auto shutter mode and fixed gain control. This mode is suitable for applications in which the lighting conditions change gradually, yet a certain fixed gain value is required. The available control functions for this mode are: Weight Fixed Gain Target Brightness Brightness Tolerance Brightness Threshold Shutter Range d. ALC Fixed/ AGC ON In this mode, the camera works with a fixed shutter speed and the AGC (auto gain control). This mode is suitable for applications in which lighting conditions change gradually yet a certain fixed shutter speed is required. The available control functions for this mode are: Weight Fixed Shutter Preset Shutter Speeds Target Brightness Brightness Tolerance Brightness Threshold AGC Range e. ALC / AGC OneShot ALC / AGC OneShot allows the user to set the shutter and gain values automatically to a desired setting, then fixes the settings. If the camera is powered-down, these temporary setting values will be lost. This is a fast convenient mode to set the fixed shutter speed and fixed gain setting simultaneously, for a given environment, provided set lighting and lensing. First, set the Target Brightness at the desired or optimum brightness level for your application, and click ALC / AGC OnShot. By doing so, the fixed shutter speed and fixed gain setting, the camera sets automatically to maintain the Target Brightness setting. In this mode, the Target Brightness slide bar is activated and can be adjusted. To change the brightness level, set a different value with the Target Brightness slide bar and select ALC / AGC OneShot again. There are two ways to set the ALC / AGC OneShot brightness level: 1) Go to ALC / AGC On and adjust the Target Brightness Bar to the desired level. Next, select ALC/ AGC OneShot. This will set the Fixed Shutter and Fixed Gain values to that brightness level. 2) Select ALC/AGC OneShot and adjust the Target Brightness slide bar to the desired value, then go back to the ALC Mode drop down menu and again click on ALC/AGC One Shot again. This will reset the shutter and gain values according to the new Brightness Target value. The available control functions for this mode are: Weight Target Brightness Brightness Tolerance Brightness Threshold AGC Range Shutter Range Software Manual 26 of 41 Ver. 2.0

31 f. ALC OneShot / AGC OFF This mode is very similar to the previous mode e. ALC / AGC OneShot above. The difference is that, in this mode, the gain is set at a fixed value by the operator and the OneShot process is used to set only the shutter speed. After the shutter speed has been set, the gain value can be further adjusted by the Gain slide bar. This mode is used to set the gain at a certain fixed value and to find optimum shutter speed. Set the fixed again value first, then click the ALC OneShot / AGC OFF selection. The available control functions for this mode are: Weight Gain Target Brightness Brightness Tolerance Brightness Threshold Shutter Range g. ALC Fixed / AGC OneShot This mode is also very similar to the previous mode e. ALC / AGC OneShot above. The difference is that in this mode the shutter speed is set at a fixed value by the operator and the OneShot process is used to set the gain value only. After the gain value has between set, the shutter speed can be further adjusted by either the Shutter slide bar or the Preset Shutter Speed Buttons. This mode is used to set the shutter speed at a certain fixed value and to find optimum gain value. Set the fixed gain value first then click the Auto Shutter OneShot / AGC OFF selection. The available control functions for this mode are: Weight Shutter Preset Shutter Speeds Target Brightness Brightness Tolerance Brightness Threshold AGC Range 2. Weight This function allows the user to define the importance or weight of physical areas on the image sensor (or image) during the calculation of the Automatic Values for Auto Gain or Auto Shutter. This function can be activated and accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC FullAuto / AGC OFF ALC Fixed / AGC ON ALC / AGC OneShot ALC OneShot / AGC OFF ALC Fixed / AGC One Shot By clicking the Weight button the ALC Weight/Area window will appear in the live image window and the image will be divided by crosshatches. a. Weight The number placed in each area signifies/determines the value of the weight given in relationship to the weight value of the other areas in calculating the effect of the auto function (i.e. the Automatic Light Compensation factor for the Auto Shutter and the AGC ). To adjust the numbers simply type in the desired weight factor or click the up or down arrows for the weight factor. The larger the number, the more affect that area of the image has on the ALC adjustment. The range of the weight factor is from 1 to 255. b. Area This control function allows the area sizes on the image to be adjusted, in order to further control the Weight impact in the ALC calculations. There are six crosshairs in the screen. Each line defines a border of the segments which have weight values as described in the above section a. Weight. Each line position can be adjusted by the X1, X2, X3, Y1, Y2, Y3 slide bars, which allows the area size to be defined. Software Manual 27 of 41 Ver. 2.0

32 3. Gain Note: Analog Gain is gain that is generated off of the CCD before signal passes to the A/D convertor after which the signal is processed digitally. As Analog Gain is increased, video noise is also increased. This control is used to set the desired level of analog gain, when the gain has a fixed value. This function is activated and can be accessed in the following ALC Mode Selections: OFF(ALC Fixed / AGC OFF) ALC FullAuto / AGC OFF ALC OneShot / AGC OFF Once the Fixed Gain is activated, the Fixed Gain slide bar can be used to adjust the analog gain to the desired level. 4. Shutter This control is used to set the desired shutter speed, when the shutter speed has a fixed value. This function is activated and can be accessed in the following ALC Mode Selections: OFF (ALC Fixed / AGC OFF) ALC Fixed / AGC ON ALC Fixed / AGC OneShot Once the Shutter is activated the slide bar can be used to adjust the shutter speed to the desired level. Note: Maximum shutter speed can be obtained by setting the slide bar to the far right end position. As the slide bar is moved towards the left, the shutter speed will gradually become shorter. Please note that at the far left position, the shutter speed goes back to the maximum speed. 5. Shutter Speed Buttons This control is used to set the shutter speed at traditional preset values. This function is activated and can be accessed in the following ALC Mode Selections: OFF (ALC Fixed / AGC OFF) ALC Fixed / AGC ON ALC / AGC OneShot ALC OneShot / AGC OFF ALC Fixed / AGC OneShot The values for the preset shutter speed buttons for fixed shutter speeds vary by different camera types. The preset shutter speeds are listed below by sensor size: VGA XGA SXGA UXGA a. 1/120 1/120 1/120 1/120 b. 1/100 1/100 1/100 1/100 c. 1/60 1/60 1/60 1/60 d. 1/50 1/50 1/50 1/50 e. 1/30 1/30 1/30 1/30 f. N/A N/A 1/25 1/25 g. Reset = 1/30 Reset = 1/30 Reset = 1/19 Reset = 1/15 Note: By clicking Reset, the shutter speed will be reset to the original value which is the longest shutter speed available at the selected mode. Software Manual 28 of 41 Ver. 2.0

33 6. Target Brightness This control is used to set the desired brightness level for all ALC automatic controls. An example of where this might be used is on a microscope. Usually a microscope will have a light source and the optics of the scope will serve as the lens train. By hooking up the camera to the microscopes coupler and putting the ALC Mode in any of the selections below, the desired brightness level of the image can be targeted by adjusting the Target Brightness slide bar. This Brightness Target level defines the brightness level you would like to maintain automatically with the automatic modes. The target brightness can be adjusted with this slide bar. This function is activated and can be accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC FullAuto / AGC OFF ALC Fixed / AGC ON ALC / AGC OneShot ALC OneShot / AGC OFF ALC Fixed / AGC OneShot 7. Brightness Tolerance This control is used to set the Brightness Tolerance level referencing to the Brightness Target value mentioned above. This control allows the upper and lower limit values of the brightness range to be set. By setting the upper and lower values of the range, the automatic gain control or automatic shutter control (collectively called ALC) is activated when actual video level exceeds the range set here. The Brightness Tolerance for ALC operations can be adjusted with this slide bar. This function is activated and can be accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC FullAuto / AGC OFF ALC Fixed / AGC ON ALC / AGC OneShot ALC OneShot / AGC OFF ALC Fixed / AGC OneShot 8. Brightness Threshold This control is used to set the Brightness Threshold level. This value supports or is related to the Brightness Target value. This function allows the upper and lower limit values of the brightness level to be set for additional control of the Automatic Gain Control and/or Automatic Shutter Control (collectively called ALC). In other words, when ALC is in operation, the automatic adjustments will halt when the brightness level reaches to this value set for the Brightness Threshold. Note: To insure a stable ALC operation, choose a smaller value for the Brightness Threshold level than the Brightness Tolerance setting. This function is activated and can be accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC FullAuto / AGC OFF ALC Fixed / AGC ON *When using one shot mode, it is necessary to preset the threshold manually by using one of the three mentioned above, prior to switching to the one shot mode for situations below. ALC / AGC OneShot ALC OneShot / AGC OFF ALC Fixed / AGC OneShot 9. AGC Range This control is used to set the AGC range. This defines the range of gain values for the AGC operation. When the gain value mode selected uses Auto Gain (AGC ON), the active range will be limited to the upper and lower values shown where the slide bar is highlighted. The active AGC range (lower and upper) can be adjusted with this slide bar. The AGC Range function is activated and can be accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC Fixed / AGC ON ALC / AGC OneShot ALC Fixed / AGC OneShot Software Manual 29 of 41 Ver. 2.0

34 10. Shutter Range The active shutter speed range (upper and lower) can be adjusted with this slide bar. When the upper and lower shutter speed values are set, the auto shutter speed will be limited only to the range shown where the slide bar is highlighted. This function is activated and can be accessed in the following ALC Mode Selections: ALC FullAuto / AGC ON ALC FullAuto / AGC OFF ALC / AGC OneShot ALC OneShot / AGC OFF Software Manual 30 of 41 Ver. 2.0

35 B. White Balance Tab Note: This camera utilizes an RGB Bayer Mosaic filter and the arrangement of R (red), G (green) and B (blue) is shown in Figure 36 below. This filter is placed over CCD so that each pixel has an R, G or B filter over it. Color interpolation is done in the PC and a full color image is created. As you see in the drawing below, there are more green pixels than red or blue pixels. For convenience purposes, we differentiate green pixels in the red rows from the ones in the blue rows as Gr and Gb respectively. R Gb Gr B Figure 36: Color Diagram 1. White Balance Mode Selection Figure 36: White Balance Tab in Advanced Settings Through the White Balance drop down menu, the following four White Balance modes are selectable: a. OFF By selecting this mode, the camera works without white balance processing. This mode would be utilized in those cases where raw data is desired. Due to the Bayer color filter, the picture becomes green tinted as there are more pixels on the CCD that have green filters on them than there are with red or blue filters on them. (See illustration above.) Software Manual 31 of 41 Ver. 2.0

36 b. Manual By selecting this mode, the camera works with manual white balance. This mode is highly recommended in applications in which the color temperature of the light is constant. By adjusting Color Gain R, Color Gain Gr, Color Gain Gb and Color Gain B, the desired level of White can be set to define the manual white balance. The meaning of each of the four slide bars that are activated in this mode are as follows: Color Gain R: Color gain for all red pixels. Color Gain Gr: Color gain for all green pixels in the red rows. Color Gain Gb: Color gain for all green pixels in the blue rows. Color Gain B: Color gain for all blue pixels. c. Full Auto By selecting this mode, the camera activates Auto White Balance (AWB). In AWB the camera constantly calculates what it thinks is white based on the scene it is currently processing. This mode is recommended in applications in which the camera is constantly exposed to different color temperatures of light. The following slide bars are activated in the AWB mode: Color Gain Gr Color Gain Gb Auto Target R Auto Target B By adjusting Color Gain Gr, Color Gain Gb, Auto Target R and Auto Target B, the desired level of White can be set to help define the Automatic White Balance processing. d. OneShot By selecting this mode, the camera works with OneShot Auto White Balance (also referred to as Push to Set White Balance ). This mode is highly recommended for applications in which the color temperature of the light is constant during a session but may vary from session to session. This is a temporary White Balance setting and will be lost when the camera is powered down. Therefore, the OneShot Auto White Balance settings will need to be reset for every session. Note: The OneShot feature can also be accessed through the Options menu and by a push-icon button on the toolbar; please refer to Page 17 for further details. Follow the procedures below to use this OneShot White Balance feature and to set the white balance for this session: Under the proper lighting source, place a white object in front of the camera so that the whole screen is covered by the white target. Click OneShot white balance and keep the white object for a few seconds until the screen becomes pure white or gray (no color tint). At this moment, the white balance is properly set for the particular light source and lens currently being used. The camera will retain this white balance setting until the process is executed again or until the camera is powered down. If or when the color temperature of the light source changes, repeat this process to reset the white balance value. The following slide bars are activated in the OneShot mode: Color Gain Gr Color Gain Gb Auto Target R Auto Target B 2. Manual Gain R This slide bar is used to adjust the red color level of the white balance. 3. Manual Gain G This slide bar is used to adjust the green in the red rows. This setting must be equal to setting or value of Color Gain Gb. Lines may appear on the image when Color Gain Gb and Color Gain Gr are not equal. 4. Manual Gain Gb This slide bar is used to adjust the green in the blue rows. This setting must be equal to the setting or value of Color Gain Gr. Lines may appear on the image when Color Gain Gb and Color Gain Gr are not equal. Software Manual 32 of 41 Ver. 2.0

37 5. Manual Gain B This slide bar is used to adjust the blue color level of the white balance. 6. Auto Target R This slide bar is used to adjust the red color level of the white balance in Full Auto or One Shot modes. 7. Auto Target B This slide bar is used to adjust the blue color level of the white balance in Full Auto or One Shot modes.. Software Manual 33 of 41 Ver. 2.0

38 C. Color Tab Figure 37: Color Tab in Advanced Settings 1. Saturation / Hue Mode Through the drop down menu, the following two Hue / Saturation modes are selectable: a. OFF In this mode the color saturation and hue settings cannot be changed. The camera operates with factory default Hue and Saturation settings in this mode. b. ON In this mode the color saturation and hue settings can be changed by adjusting the respective slide bars. 1) Saturation This function is activated when the Hue/Saturation Mode is set to ON. The saturation setting can be adjusted with the slide bar. The set range is from 0.0 [0] to 2.0 [200]. 2) Hue This function is activated when the Hue/Saturation Mode is set to ON. The hue setting can be adjusted with the slide bar. The set range is from [-1800] to [1800]. Software Manual 34 of 41 Ver. 2.0

39 2. Color Matrix window The following appears by selecting the Color Matrix button. This widow is for detailed color adjustment. Do not adjust these settings if the default color is satisfactory for the application. Figure 38: Color Matrix Window The 4x3 Matrix above allows for 12 parameters to be used to set the Color Matrix of the image. Any changes made to the parameters are only reflected to the image after the OK or APPLY button is selected. R, G and B are the result of the formulas where the R color, G color and B color have been revised by the formula. If the standard core color values are not acceptable, this matrix may be used to adjust those core values. If no adjustment or additional processing is needed for the core color values, then R is Red, G is Green, and B is Blue without any processing by this matrix. The values shown in this matrix is before any adjustments are made, these are the Factory Default values. The active value range which may be put into the matrix is from -32,767 to 32,767. Note: Luminance is primarily carried in the Green channel. Therefore, if, for example, the three default values are each changed from 100 to 1,000, the image will become quite saturated. If the lens is closed down to reduce the amount of light that is allowed onto the CCD, a more natural image color will be regained. This might be useful for very low light applications. However, please note that this will also increase the noise in the image. a. OK By selecting the OK button, all changes to the Color Matrix will be reflected in the Image and the Color Matrix window will close. b. APPLY By selecting the APPLY button, all changes to the Color Matrix will be reflected in the image and the color Matrix window will stay open, allowing further adjustments. c. CANCEL By selecting the CANCEL button, the values will be set at the last saved setting and the window will close. d. RESET Clicking the RESET button will replace the parameters of the Color Matrix Window with the factory default or settings that were previously saved to file. The change is reflected to the image after the OK or APPLY button is selected. e. GRAY Clicking the GRAY button will set the Color Matrix to a monochrome image setting. The change is reflected to the image after the OK or APPLY button is selected. f. REVERSE Clicking the REVERSE button will set the Color Matrix to a negative image setting. This change is reflected to the image after the OK or APPLY button is selected. Software Manual 35 of 41 Ver. 2.0

40 D. Color Gamma Tab Through this tab, unlike the Gamma Correction under the Y tab, the color gamma correction factors can individually be set for R, Gr, Gb, and B. Note: As described before, Gamma correction or adjustment is setting linearity of gray scale representation. With the adjustments below, the grayscale can be set rendering on individual color segments. Gamma value 1 represents linear transmission. In the case of this camera, when the gamma value is set below 1, the gray scale of brighter side is expanded and the gray scale of darker side is suppressed. On the other hand, when the gamma value is set above q, the gray scale of brighter side is suppressed and the gray scale of darker side is expanded. Figure 39: Color Gamma Tab in Advanced Settings The slide bar is activated and or accessible by setting any of the Gamma Mode selections to ON or Reverse. Adjust the Color Gamma volumes with the slide bars. 1. R Gamma Mode Through this drop down menu, the following three R Gamma Mode control options are selectable: a. OFF In this mode, the camera works with the R gamma equal to 1.0. The R Gamma cannot be adjusted in this mode. b. ON In this mode, the R Gamma can be adjusted.

Gb Gamma Mode Through this drop down menu, the following three Gb Gamma Mode control options are selectable: a. OFF By selecting this mode, the camera works with the Gb Gamma equal to 1.0.The Gb Gamma cannot be adjusted in this mode. It is recommended that this setting and Gb Gamma setting should be equal otherwise horizontal stripes may appear throughout the image. b. ON By selecting this mode, the Gb Gamma can be adjusted. The Gb Gamma is adjustable with the Gb gamma slide bar. It is recommended that this setting and Gb Gamma setting should be equal otherwise horizontal stripes may appear throughout the image. c. Reverse This mode creates a gray scale reversed-image in Gb and provides gamma correction at the same time. In this mode, what would normally be a bright pixel is represented as dark and vice versa. 4. B Gamma Mode Through this drop down menu, the following three B Gamma Mode control options are selectable: a. OFF In this mode, the camera works with the B Gamma equal to 1.0. The B Gamma cannot be adjusted in this mode. b. ON In this mode, the B Gamma can be adjusted. The B gamma is adjustable with the B Gamma slide bar. c. Reverse This mode creates gray scale reversed-image in B and provides gamma correction at the same time. In this mode, what would normally be a bright pixel is represented as dark and vice versa. Software Manual 37 of 41 Ver. 2.0

42 E. Gamma / Sharpness Tab Figure 40: Gamma/Sharpness Tab in Advanced Settings 1. Gamma Mode Through the Gamma Mode drop down menu, the following four Gamma modes are selectable: a. OFF In this mode, the gamma value is set at 1.0. This mode also prohibits the gamma value from being changed. b. ON By selecting this mode, the gamma value can be changed. In this mode, the gamma value can be adjusted with the Gamma slide bar. c. Reverse This mode creates a gray scale reversed-image and provides gamma correction at the same time. In this mode, pixels which would normally be bright are represented as dark and vice versa. In this mode, the gamma value can be adjusted with the Gamma slide bar. 2. Sharpness Mode Through the Sharpness Mode drop down menu, the following four Sharpness modes are selectable: a. OFF The sharpness setting cannot be adjusted in this mode. The camera works with minimum sharpness gain and minimum sharpness coring settings in this mode. b. ON The sharpness setting can be adjusted in this mode. This adjustment is also known as aperture correction. The available control functions for the ON mode are: 1) Sharpness Gain This function is activated and can be accessible when the sharpness mode is set to ON. The sharpness setting can be adjusted with the slide bar. 2) Sharpness Coring This function is activated and can be accessible when the sharpness mode is set to ON. The detection range of sharpness enhancement can be adjusted with the slide bar. Note: This adjustment is also called aperture correction or edge enhancement. The principal of this correction is adding edge enhancement information based on the gray scale signal level difference and image sharpness is increased significantly. However, as the nature with this principle, as the Sharpness Gain increases, the background noise becomes more noticeable. In such a case, the Sharpness Coring can be increased and the background noise will reduce significantly. Please note, if the Sharpness coring is increased too much, eventually the effect of Sharpness Gain will also become null. Software Manual 38 of 41 Ver. 2.0

43 F. Other Tab Figure 41: Other Tab in Advanced Settings 1. Scan Mode Through the drop down menu, the following five scan method modes are selectable: a. Normal By selecting this mode, a full screen image is displayed. b. 1/2 Partial By selecting this mode, approximately half of the vertical center screen image is displayed and frame rate increases. c. 1/4 Partial By selecting this mode, approximately one-quarter of the vertical center screen image is displayed and frame rate increases. Note: For the Scan Mode, by selecting the 1/1, 1/2 or 1/4 Partial mode, the range of the shutter speeds for the fixed shutter on the Gain/Shutter tab is expanded beyond the range available under the Normal mode. This expanded range of shutter speeds can be used to set an extended exposure time. For example, with a Sentech UXGA color USB camera, the slowest shutter speed under the Normal scan mode is 1/15 sec., however by setting the scan mode to 1/1 Partial mode, the slowest shutter speed is now expanded to 1/ 4.69 sec. This is a convenient method to either (a) slow down the frame rate of the camera or (b) increase the sensitivity. Note: If the 1/2 Partial or 1/4 Partial mode is selected, the scan rate of the image increases. These modes are suitable for the applications which require the higher scan rate of the images. 2. Clock This function allows the Clock Speed of the camera readout to be set. The following three Pixel Clock Speeds are selectable through this drop down menu: a. Normal By selecting this mode, the pixel clock speed is set to normal. If the PC has enough performance and it is not occupied with other tasks, the following scan rates can be achieved on the Sentech USB cameras: - VGA = frames per second, - XGA = frames per second - SXGA = frames per second - UXGA = frames per second Software Manual 39 of 41 Ver. 2.0

44 b. 1/2 By selecting this mode, the pixel clock speed is 1/2 of the normal pixel clock speed (half speed of Normal). c. 1/4 By selecting this mode, the pixel clock speed is 1/4 of the normal pixel clock speed (quarter speed of Normal). Note: As the pixel clock speed slows down, the frame rate will also slow down accordingly. As the frame rate slows down, the light sensitivity of the camera increases due to the longer exposure time. Hence, for low light applications, which require higher sensitivity, selecting either the 1/2 or 1/4 Clock Speed, may be effective in helping increase the brightness of the image. Additionally, this setting may help improve the SN ratio. 3. Still Image Pixel Format Through the Still Image Pixel Format drop down menu, the two following formats are selectable. These selections define the signal format of the still image recording. Choose appropriate format according to requirements of the application which will be used. Some applications require a BGR24 format and some require a BGR32 format. The image qualities of these are the same. a. BGR24 By selecting this format each pixel of the still image is represented in 24 bits. b. BGR32 By selecting this format, each pixel of the still image is represented in 32 bits. To achieve 32bits/pixel format, eight additional (dummy) bits are added to make up 32bits. These additional bits do not carry any image information. 4. Color Interpolation Each pixel on the CCD has a Red, Green or Blue filter over it. This means each pixel does not have color information for two of three primary colors (i.e. green pixels are missing blue and red). The process of filling in the absent color information is called Color Interpolation. The StCamSWare Viewing Software provides five different algorithms for color interpolation. (Color Interpolation is only applicable with color cameras.) The following Color Interpolation algorithms are selectable through the drop down menu: a. OFF (Mono) By selecting this mode, the image is generated without any color information. If this mode is selected while using a color camera, a monochrome image will be generated, but the image will have geometric patterns due to the primary color filter. This mode is not recommended for color cameras. b. OFF (Color) By selecting this mode, the image appears with no color interpolation. The image generated is comprised of the raw color information (Red, Green and Blue) due to the Bayer filter. c. Nearest Neighbor Replication By selecting this mode, the color of the image is generated with the simplest color interpolation algorithm. In the case that red is needed on a green pixel, the algorithm simply copies the color from the nearest red pixel and uses that value for the missing red color information on the green pixel. The execution of the Nearest Neighbor Replication algorithm requires very limited resource from the PC, however some pixelization effect may be visible especially along sharp contrast edges. The color reproduction will also be less accurate than either the Bilinear or Bi-Cubic algorithms. d. Bilinear By selecting this mode, the camera works with the Bilinear algorithm, which is a more complex color interpolation algorithm. This generates a more accurate color reproduction and smoother edge renderings than the Nearest Neighbor method, put requires more computational power from the PC. The algorithm is as follows: Interpolation of green pixels: the average of the upper, lower, left and right pixel values is assigned as the G value of the interpolated pixel. For example: G8 = (G3+G7+G9+G13) / 4 Interpolation of red/blue pixels: Interpolation of a red/blue pixel at a green position: the average of two adjacent pixel values in corresponding color is assigned to the interpolated pixel. For example: B7 = (B6+B8) / 2; R7 = (R2+R12) / 2 Interpolation of a red/blue pixel at a blue/red position: the average of four adjacent diagonal pixel values is assigned to the interpolated pixel. For example: R8 = (R2+R4+R12+R14) / 4; B12 = (B6+B8+B16+B18) / 4 Software Manual 40 of 41 Ver. 2.0

45 e. Bi-Cubic By selecting this mode, the image appears with the most sophisticated color interpolation algorithm in this software. Each Interpolated color value is defined based on a certain equation factored by the distances and color values of the surrounding pixels. This creates very smooth edge rendering and excellent color reproduction; however, this method also requires most computational power from the PC. This interpolation algorithm is generally described as the next formula: C(x,y) = c(xk, y1) h( x-xk ) h( y-y1 ) K 1 In this software, we utilize the method called One-Variable Cubic interpolation in which the pixels up to two pixels away from the subject pixel may be the object for this color interpolation. (See Figure 42) Figure 42: One-Variable Cubic Interpolation 5. Mirror Mode Mirror Mode allows the orientation for the image to be changed digitally. Through this drop down menu, the following four mirror modes are selectable: a. OFF By selecting this mode, a normal image is displayed. b. Horizontal By selecting this mode, a so-called mirror image (horizontally reversed image or right/left converted image) is displayed. c. Vertical By selecting this mode, a vertically reversed (top / bottom flip) image is displayed. d. Horizontal/Vertical By selecting this mode, both a vertically and a horizontally reversed image (180 degree rotated image from the original image) is displayed. 6. Rotation The Rotation function allows the image to be digitally rotated. The following three rotation modes are selectable: a. OFF By selecting this mode, a normal image is displayed. b. CLOCKWISE_90 By selecting this mode, the image will rotate 90 degrees clockwise from the original preview image. c. COUNTERCLOCKWISE_90 By selecting this mode, the image will rotate 90 degrees counterclockwise. Software Manual 41 of 41 Ver. 2.0
