Has anyone connected a non Micron CMOS image sensor to a DM355.
I'm having trouble getting the correct color output on my display and
I'm wondering if I'm setting up the CCDC or the IPIPE incorrectly on the
DM355.
The imager sensor is a Omnivision 3630 which has a bayer pattern of:
BGBG
GRGR
BGBG
GRGR
The colors I'm seeing on the display are:
* Cyan input displays as red
* Magenta input displays as yellow
* Yellow input displays as light pink
* Red input displays as dark green/gray
* Green input displays as blue
* Blue input displays as black
I've tried adjusting the COLPTN register in the CCDC and that doesn't
seem to have any effect on the output. That wasn't what I expected, I
figured changing what the CCDC saw as a bayer pattern would drastically
change the output. Am I misunderstanding what that register is for?
I've also noticed that in the VPFE docs, that the IPIPE states that the
only supported color filter arrangement is:
GB
RG
Do I have to use the color space converter in the CCDC to change the
bayer pattern?
I've proved that my display is correct by feeding a YCC image to the
display and having it displayed as I expected it to be.
I'd welcome any suggestions on what I could be doing wrong here.
thanks,
Jeff
