An X-Y addressable CMOS APS with compact pixel pitch

摘要

An active pixel sensor that is x-y addressable that uses serial shift registers to select an image window resulting in less semiconductor area being employed compared with prior art address decoding techniques comprising: an x-y addressable imager having signal lines in both x and y directions; at least one pair of serial shift registers operatively connected to the x-y imager such that there is at least one serial shift register in each x and y directions to select signal lines to be applied to the x-y imager; and loading means for placing bit patterns into the shift registers.
