Spectral response of digital cameras
by Bob2004 - 5/26/04 4:17 AM
Does anyone have information, preferably graphs, of the spectral response of CCD's and CMOS chips in modern digital cameras? Thx in advance.

We looked at that in the CCTV designs and found not much varience in each process. For instance, a CMOS sensor in black & white would have the same spectral response as any other black and white CMOS imager at the same temperature. Some of the PDFs show such a response, but for non-human imaging work, the responses are either tailored for humans or corrected in the DSP.
http://www.dpreview.com shows the standard color board that is used quite often.

I must add that the imager response is often documented, but not very usable since most cameras you see in the consumer models add filters either directed on the imager or in the lens. These affect the final response curve.
I want to add I didn't note the sensitivity measurements since you asked about spectral response and not light levels.
