Software and Hardware Setup
RGBG 8 bit CL Deca, max line rate 48 kHz without AOI and 85
MHz CL clock
Note:
only 8190 pixels transmitted, no color interpolation
This timing can be used for applications that require line rates up to 48 kHz and therefore
must use Camera Link Deca mode and two cables.
Due to the bandwidth limitation of Camera Link Deca, it is only possible to output the two
lines of the color sensor—where one 8K line is green and the other 8K line is alternating red
and blue pixels—as 4K of each. This is defined as the RGBG format. The RGBG output
format is not defined in the Camera Link specification for Deca. The RGBG format is such
that when using a Camera Link frame grabber compatible with the Deca format configured
for the mono standard, the R, G, B and then G pixels will be written sequentially into the
frame grabber buffer. This process simplifies the extraction of the RGBG data from the
frame grabber buffer by the host application. However, the frame grabber or host
application will need to perform the necessary red and blue interpolation to generate RGB
pixel data. This interpolation operation will increase the amount of pixel data by 50%.
Note
: when using an AOI with this RGBG mode, you must consider the available (i.e.
potential lack of) red and blue pixel data at the AOI boundaries when they are performing
interpolation.
