Abstract
There is provided a method and system for extending image sensor dynamic range using coded pixels. The method including: providing pixel codes to pixels in the photodetector array for each subframe of a frame; receiving a sensor readout of each of the pixels in the photodetector array for each subframe; for each subframe, based on the pixel code, routing each sensor readout value for collection at one or more taps or to a drain; combining the collected sensor readout values at each of the taps to determine a single pixel value for the frame; and outputting the single pixel value for each pixel for the frame.
