Abstract:
1. A solid-state image sensor comprising a pixel array in which a plurality of pixels are arranged so as to form a plurality of lines along a first direction and a plurality of lines along a second direction crossing the first direction, wherein each of the plurality of pixels includes a photoelectric converter and a readout circuit configured to output a signal in accordance with charges generated in the photoelectric converter to a signal line, the readout circuit includes a group of transistors which are disposed so as to form a current path fed by a current source, the plurality of lines along the first direction includes a first line and a second line which are adjacent to each other, the readout circuit of a pixel in the first line and the readout circuit of a pixel in the second line are disposed between the photoelectric converter of the pixel in the first line and the photoelectric converter of the pixel in the second line, and directions of currents respectively flowing through the group of transistors in the readout circuit of the pixel in the first line and the group of transistors in the readout circuit of the pixel in the second line are the same.
