Patent ID: 8026956

Claim:
An image sensor, comprising: a photoelectric conversion unit including a plurality of photoelectric conversion elements, the photoelectric conversion elements being disposed in a two-dimensional matrix, the photoelectric conversion elements converting received light into electric charge and accumulating the electric charge; a reset processing unit for performing a reset process, the reset process being a process of removing electric charge accumulated in each of the photoelectric conversion elements of the photoelectric conversion unit in a first sub-frame period among the first to N-th sub-frame periods, the N being a natural number of two or more, the first to N-th sub-frame periods being obtained by dividing each frame period of a frame rate corresponding to a normal exposure time into an N number of periods in the first to N-th order; and a pixel signal readout unit for reading out a pixel signal in a non-destructive manner, the pixel signal being an electric signal corresponding to an amount of electrical charge accumulated in each of the photoelectric conversion elements in each of the first to N-th sub-frame periods.
