Point Grey Flea3 GigE - Analog-To-Digital Converter

Point Grey Flea3 GigE Technical Reference 1 Flea3 GigE Specifications
1.3 Analog-to-Digital Converter
The camera sensor incorporates an analog to digital converter (ADC) to digitize the images produced by the CCD.
The Flea3 GigE's ADC is configured to a fixed bit output. If the pixel format selected has fewer bits per pixel than the
ADCoutput, the least significant bits are dropped. If the pixel format selected has greater bits per pixel than the ADC
output, the least significant bits are padded with zeros.
A 12-bit conversion produces 4,096 possible digital image values between 0 and 65,520, left-aligned across a 2-byte
data format. The four unused bits are padded with zeros.
12-bit, 50 MHz
0 LSB to 255.75 LSB, 0.25 LSB steps
-3 dB to 6 dB, 3 dB steps
6 dB to 42 dB, 10-bit
The bit depth of the output varies between sensors and can be seen in the table below. Image data is left-aligned across
a 2-byte format. The least significant bits, which are the unused bits, are always zero.
For example, for a 12 bit output, the least significant 4 bits will be zeros in order to fill 2 bytes. E.g. 0xFFF0.
