MityCAM-120MXS 12bit two least significant bits always 0
Added by Doug MacEwen over 4 years ago
Hello,
I have been working with the MityCAM-120MXS in with the BayerRG12p pixel format (over USB) and noticed that the pixel values increment by 4. I dug around a little and it appears that the two least significant bits are never used, essentially making the output 10bit. I checked my implementation against the GenTL viewer provided by Critical Link and noticed that the pixel values increment by 4 there as well.
I was hoping that you could provide some guidance on whether this is expected behavior, I miss configured the camera, or if (and how) I should file a bug report. Let me know if there is any more information I can provide.
Thank you!
Doug

Hi Doug,
The 120 MP Canon sensor is really a 10 bit sensor, but the MityCAM camera framework does not support 10 bit-per-pixel output packing at this time, so we packed the 10 bits into a 12 bit word with a left shift so that a full scale signal would result in a full scale output on the display. The bottom two bits will be zero.
I am sorry for the confusion.

Good to know! No problem, I just wanted to make sure I wasn't missing something. Thanks!
