22. the ILUT and passes the output value to the frame region of interest Pixel values range from 0 to 255 The DT3152 frame grabber board supports one ILUT Using software you can specify the relationship between the pixel input value and the ILUT output value by loading the ILUT with different processing setups For example you can pass an image unaltered the default setting known as identity or you can perform pixel point operations such as image multiplication and division intensity correction and reverse video before passing the image on 19 Chapter 2 20 As an example assume that the ILUT is loaded with the identity pattern An input value of 0 black in monochrome mode has an output value of 0 black in monochrome mode An input value of 1 has an output value of 1 An input value of 2 has an output value of 2 and so on up to an input value of 255 which has an output value of 255 or white in monochrome mode As another example if you load the ILUT with an inverse or negative pattern an input of 0 has an output value of 255 an input value of 1 has an output pattern of 254 and so on up to an input value of 255 which has an output value of 0 or black in monochrome mode Note that in addition to ILUTs passthru operations make use of passthru LUTs For more information about passthru LUTs refer to page 42 Principles of Operation Sync Signals This section describes the following aspects of the sync
23. the sync threshold to determine when the sync is asserted The sync period is defined as the portion of the sync signal that falls below the sync threshold The sync is then used to generate the horizontal and vertical timing for the input section of the DT3152 board On the DT3152 you can program the sync threshold Possible threshold limits are 50 mV 75 mV 100 mV and 125 mV nominal is 125 mV Principles of Operation Variable Scan Video Signals When using variable scan video signals the horizontal line and vertical frame sync come directly from the video source Two inputs are provided on connector J2 to accept separate horizontal and vertical sync signals LINE_SYNC pin 2 is used to indicate the start of a line FRAME_SYNC pin 4 is used to indicate the start of a frame By default the DT3152 uses the rising edge of the external sync signals to reset the horizontal and vertical counters In cases where the video is referenced to the falling edge of the external LINE_SYNC and FRAME_SYNC signals you can invert the sync signals on the board using software A variable scan acquisition is initiated and controlled like any other single frame or multiple frame acquisition Figure 8 on page 24 illustrates variable scan timing and data storage 23 Chapter 2
24. the sync can be detected by specifying a horizontal search position a horizontal insert position a vertical search position and a vertical insert position The horizontal sync search position is the pixel location within a line at which the DT3152 board begins to search for the horizontal sync If the horizontal sync is not detected before the horizontal sync insert position is reached the DT3152 board inserts a horizontal sync to synchronize to the video signal The default value for the horizontal search position is 95 0 of the total pixels per line The default value for the horizontal insert position is 101 5 of the total pixels per line The vertical sync search position is the line location within a field at which the DT3152 board begins to search for the vertical sync If the vertical sync is not detected before the vertical sync insert position is reached the DT3152 board inserts a vertical sync to stay in syne with the video signal The default value for the vertical search position is 50 0 of the total lines per field The default value for the vertical insert position is 115 of the total lines per field By setting the sync search position immediately before the falling edge of the sync and setting the sync insert position immediately after the falling edge of the sync you can prevent the DT3152 board from searching for syncs except where they are expected 25 Chapter 2 26 If you are switching among multiple input

31. By default the offset is 53 86 mV for 60 Hz and 0 V for 50 Hz Gain Gain is the value you use after the offset is applied to multiply the amplitude of the signal thereby increasing or decreasing the overall range of the signal To maintain the accuracy of the ADC at low light levels and to support a wider range of video inputs the DT3152 provides gains of 0 5 1 2 and 4 By default the gain is 1 To determine the gain to use calculate the maximum voltage of your video signal after the offset is applied Then use the values in Table 1 to determine the gain to use Principles of Operation Table 1 Gain Values If Use a Gain of Vmax Offset gt 1 28 V 0 5 0 64 V lt Vmax Offset lt 1 28 V 1 0 32 V lt Vmax offset 0 64 V 2 Vmax Offset 0 32 V 4 Reference Reference is the maximum voltage after offset and gain have been applied that you want to digitize Reference is defined as follows reference gain V max offset The DT3152 board digitizes the signal between 0 0 V and the reference voltage The DT3152 Device Driver supports a minimum reference of 0 V and a maximum reference of 1 28 V in 256 steps of 5 mV Note however that the hardware uses 64 steps of 19 mV By default the reference used by the device driver is 660 mV for 60 Hz and 715 mV for 50 Hz Note For proper operation once offset and gain are applied the difference between the adjusted minimum volta
32. C coupled video signal has chrominance information on it as is the case with the NTSC and PAL video formats you can use software to apply a chrominance notch filter to remove the chrominance information The chrominance notch filter for 60 Hz is set to 3 58 MHz while the chrominance filter for 50 Hz is set to 4 43 MHz By default no filter is selected Black and White Levels Black level is defined by DT Open Layers as the voltage below which all other voltages are digitized to black White level is defined as the voltage above which all other voltages are digitized to white For ease of use both of these voltages are measured at the camera s output On the DT3152 board if you are using a gain of 1 use software to set a black level and a white level If however you need to use a gain other than 1 use software to set the offset gain and reference value The following subsections describe how to use the offset gain and reference settings on the DT3152 board to adjust the black and white levels of the video signal 11 Chapter 2 12 Offset The offset is the voltage you apply to the minimum value V min of your video signal to zero it The offset is defined as follows offset Y min All data below 0 V is digitized as black pixels The DT3152 Device Driver supports a minimum offset of 1 08 V and a maximum offset of 1 07 V in increments of 8 4 mV Note however that the hardware uses 64 steps of 33 6 mV
