Claim:
1. An image sensor comprising a semiconductor chip and a package covering the semiconductor chip, the semiconductor chip comprising a pixel portion including a plurality of pixels arranged to form a plurality of rows and a plurality of rows, a row selection unit configured to select a row of the plurality of columns, a memory, a readout unit configured to write, in the memory, a first signal corresponding to a reset level from pixels of the row selected from the plurality of rows by the row selection unit and a second signal corresponding to an optical signal level from the pixels of the row selected from the plurality of rows, an output unit configured to output an image signal corresponding to the first and second signals written in the memory, a control unit configured to output a control signal to an output pin of the package via an output pad of the semiconductor chip, and a pad to which a power supply voltage is supplied from outside the semiconductor chip, wherein the control signal indicates a write period within a row-selected period during which the row is selected from the plurality of rows by the row selection unit, and wherein during the write period, the first and second signals associated with the row selected from the plurality of rows are written in the memory.
