Abstract:
1. An imaging apparatus comprising: a solid-state imaging element having a structure in which a large number of pixel cells each comprised of a combination of a main photosensitive pixel having a relatively large area and a dependent photosensitive pixel having a relatively small area are arranged according to a predetermined arrangement form, and a signal based on a signal charge photoelectrically converted with said main photosensitive pixel and a signal based on a signal charge photoelectrically converted with said dependent photosensitive pixel can be selectively acquired; an imaging signal acquirement controlling device which performs control to acquire an imaging signal from said solid-state imaging element; a main black level correction value determining device which determines a black level correction value of the main photosensitive pixel based on a signal obtained from said main photosensitive pixel; a dependent black level correction value determining device which determines a black level correction value of the dependent photosensitive pixel by calculation from the black level correction value of the main photosensitive pixel determined by said main black level correction value determining device; and a black level correcting device which performs black level correction of the imaging signal acquired from said main photosensitive pixel based on the black level correction value of the main photosensitive pixel determined by said main black level correction value determining device, and performs black level correction of the imaging signal acquired from said dependent photosensitive pixel based on the dependent photosensitive pixel determined by said dependent black level correction value determining device.
