1. An image sensor comprising:
a pixel region where a plurality of pixels each including a sensor element that detects a naturally occurring physical quantity and converts the physical quantity into an electric signal are arranged in two dimensions in a row direction and a column direction;
a row selection unit that selects any of the pixels in the pixel region in units of rows and contributes to readout of the electric signal from each of the pixels and resetting of an accumulated charge;
a pixel readout unit that reads out the electric signal from each of the pixels selected by the row selection unit in column-parallel; and
a column selection unit that selects the pixel in any column from a pixel row selected by the row selection unit and controls a charge accumulation amount of the selected pixel, wherein
the column selection unit is provided with shift registers, a pixel control signal inputted to the column selection unit is transferred in the row direction by the shift registers, and column selection signals are simultaneously outputted, respectively, from the shift registers in response to a reading timing signal inputted to the column selection unit.
