XML parameters related to Sensor Tap Settings are as follows.
XML Parameters
ImageFormatControl
When you set the Sensor Digitization Taps parameter to One, only the left video amplifier (Video L) will be
used to output the video data as shown in the Figure 9.6. And when you set the Sensor Digitization Taps
parameter to Two, both Video L and Video R will be used to output the video data as shown in the Figure 9.7.
When LVDS signals converted from the video data through ADC are transmitted to FPGA, the signal data will be
stored in the line buffer of FPGA until the transmission of one horizontal line is completed. Figure 9.8 and 9.9
show the structure which reorders and stores one line video data in the line buffer of FPGA according to the one
tap and two taps settings. After completing one line transmission, the data goes through image processing. Then,
the data will be reordered according to the Pixel Format parameter setting value and stored in the frame buffer.
