摘要： An arithmetic circuit, which is retained by each pixel in a conventional image sensor, is shared by each column. Signal processing circuits of different configurations are provided on signal transmission paths in an upward direction and a downward direction of a vertical signal line for extracting an image signal from each pixel, whereby image output processing and arithmetic processing are performed completely separately by the different circuit blocks. Thus, image quality of an actual image is improved and optimum design for arithmetic processing is made possible. Specifically, an I-V converter circuit unit, a CDS circuit unit and the like are provided on the image output side. A current mirror circuit unit, an analog memory array unit, a comparator unit, a bias circuit unit, a data latch unit, an output data bus unit and the like are provided on the arithmetic processing side.
