Abstract: A compressive sensing image sensor includes: a pixel array; and a readout circuit configured to receive pixel data on a shot image in an analogue form, and to process the pixel data, wherein the pixel array includes a plurality of blocks each having a plurality of pixels and arranged in an array form, wherein the circuit includes: a compressive sensing multiplexer to which a plurality of pixel data outputted from a corresponding block from among the plurality of blocks are inputted; an LFSR configured to arbitrarily select at least one pixel data from the plurality of pixel data inputted to the compressive sensing multiplexer; and a delta-sigma ADC configured to receive the at least one pixel data selected by the LFSR, to delta-sigma modulate the received at least one pixel data, and to generate compressive sensing data for restoring an image of the corresponding block from among the shot images.
