Patent ID: 8902294

Claim:
An image capturing device which includes a single optical pickup system and an imaging element that has a first pixel group and a second pixel group which respectively perform photoelectric conversion on light fluxes passing through different regions of the single optical pickup system, and which is capable of generating an image including pixel data of the first pixel group and pixel data of the second pixel group by imaging the same scene using the first pixel group and the second pixel group, the image capturing device comprising: pickup mode setting unit that receives input setting of either a first plane pickup mode or second plane pickup mode in which a planar image is acquired by performing pixel addition on the pixel data of the first pixel group and the pixel data of the second pixel group; pickup execution control unit that acquires a planar image by performing pixel addition on the pixel data of the first pixel group and the pixel data of the second pixel group in such a way as to expose the first pixel group and the second pixel group of the imaging element during a same exposure time in a case of pickup in the first plane pickup mode, and acquires a wide dynamic range planar image by performing pixel addition on the pixel data of the first pixel group and the pixel data of the second pixel group in such a way as to expose the first pixel group and the second pixel group of the imaging element during different exposure times in a case of pickup in the second plane pickup mode; a diaphragm device that is arranged in a light path through which the light fluxes which are incident to the imaging element pass; and diaphragm control unit that, in a case of pickup in the second plane pickup mode, sets a diaphragm value of the diaphragm device to a value which is greater than a diaphragm value in a case of pickup in the first plane pickup mode.
