Abstract
A solid-state image sensing apparatus having plural unit pixels, arranged in an array, for converting incident light into signal charges and outputting the signal charges as electric signals, having plural photoelectric converters, overlay-formed in a depthwise direction, for converting the incident light into the electric signals. Differential processing is performed on output signals corresponding to the signal charges and output signals corresponding to a reset status and the result of processing is outputted.
