An image sensor is provided in which a read rate can be increased and missing of data of the output signal of a light receiving element can be eliminated. There are disposed switch elements that connect the output terminals of all of a plurality of light receiving elements that output an output signal in accordance with the amount of received light. The switch elements are arbitrarily conductive connective in accordance with 1/n of the highest resolution from the highest resolution, and the output of the average value is held in respective sample/hold circuits at the plural same potential, to thereby read only arbitrary data in accordance with the resolution at the time of reading. In the case where there are unnecessary data, the data is skipped so as to increase a read rate and eliminate missing of data of the output signals of the light receiving elements.
