Patent ID: 7189951

Claim:
A solid-state image sensing apparatus comprising: a plurality of unit pixels arranged in an array, for converting incident light into signal charges and outputs the signal charges as electric signals, wherein said unit pixel comprises a plurality of photoelectric converters, overlay-formed in a depthwise direction, that convert the incident light to the signal charges; and a differential processing unit adapted to perform a differential processing on output signals corresponding to signal charges in said plurality of photoelectric converters and output signals corresponding to a reset status and outputting signals obtained by the differential processing, wherein said differential processing unit having; a first holding capacitor that holds the output signals corresponding to the signal charges provided for an output line; and a second holding capacitor that holds the output signals corresponding to said reset status provided for said output line, wherein a plurality of difference signals between the signals held in said first and second holding capacitors are time-sequentially outputted.
