PROBLEM TO BE SOLVED: To solve the problem that, as to thinned-out readout for an electronic viewfinder, because electrical charge accumulation control is set for use with the electric viewfinder, a fault occurs in focus detection.SOLUTION: An image pickup device comprises: a readout unit for reading out a pixel signal by controlling, for each of a plurality of regions into which an image pickup region having a plurality of pixels two-dimensionally arrayed is divided, the accumulation of pixels included in each of the plurality of regions; an arithmetic unit for calculating an evaluation value based on the pixel signal; an image generation unit for generating an image by using the pixel signal; and a control unit for exerting control so that accumulation and readout is executed differently by the readout unit for a region, among the plurality of regions, which is read out when the pixel signal is outputted to the arithmetic unit and for a region which is read out when the pixel signal is outputted to the image generation unit. |
