Patent attributes
An Image sensing apparatus employing a multi-chip system and having a super-parallel circuit structure capable of performing processes such as image processing in real time. A first chip of a first of a first stage has first pixel circuits each having an optical sensor and first processing circuits and arranged in a matrix. A second chip of a second stage has second pixel circuits each having an analog memory for storing analog information from the preceding stage and second processing circuits and arranged in a matrix so as to correspond to the first pixel circuits. In each of the first and the second chip, each of the first and the second processing circuits receives an analog signal from another first and second processing circuit in the vicinity so as to perform first and second analog processing and performs circuit noise compensation by parallel calculation.
