Patent ID: 6992713

Claim:
A single chip, CMOS imaging device comprising: an array of pixels for providing a signal representing a scene; pixel reset circuitry for resetting said pixels in said array of pixels according to a reset sequence, wherein said reset sequence controls both timing and reset potential; a row of extended dynamic range sample and hold circuits for receiving a signal from said array of pixels; a row of linear sample and hold circuits for receiving another signal from said array of pixels; memory control and histogram circuitry which is configured to be used to generate a histogram of said signal from said array of pixels and to determine if said histogram of said signal is within predetermined limits, wherein said reset sequence is configured to be adjusted if said histogram of said signal is not within said predetermined limits; an image processor for determining a controllable function and for processing a plurality of signals received from said extended dynamic range sample and hold circuits and said linear sample and hold circuits according to said controllable function to form a processed video signal; and a memory for storing said controllable function and said processed video signal.
