A method and apparatus subsampling a plurality of signals from one frame of a pixel array, pixels within the pixel array belonging to one of at least two sets, each set configured to sense values of a same image parameter, includes controlling integration times for first and second signals for each set output from the pixel array, controlling including using a first integration time for the first signal of the set and using a second integration time, different than the first integration time, for the second signal of the set, and calculating a synthesized value for each set using the first and second signals having different integration times.
