Question for Martin:

I have Quickcam Pro for Notebooks, PID=0991.

When I put it in Bayer mode, I can get a full image without truncation at two resolutions: 1600x1200 and 800x600. So, what is the natural resolution or size of the chip, i.e, what is the total pixel count?

If the chip size is 1600x1200, how is the raw data computed for the 800x600 output mode: is there any binning and averaging involved or is it just that only 50% of pixels for each color (i.e. every second one) are acquired and sent? And what is done for 1600x1200 mode if 800x600 is the chip size?

As a rule of thumb the largest Bayer mode resolution corresponds to the sensor size. That implies that upscaling does not occur.

In 800x600 Bayer mode there is nothing fancy happening. Only half the sensor's pixels are read. However, this is subject to change and it might differ from camera to camera, so I wouldn't rely on any particular behavior.

Thanks, Martin.
