Abstract

An image sensing apparatus comprises: a photodetector for converting an optical image to a charge signal; a recombination circuit for recombining a portion of the charges in the photodetector with the majority carrier; an instruction circuit for instructing change-over between the still mode, in which only one predetermined image signal is formed in the photodetector, and the movie mode, in which a plurality of image signals are formed; and a controller for switching the recombining capability by the recombination circuit during the formation of an image in accordance with an instruction output of the instruction circuit, in which the recombining capability in the still mode is controlled so as to be higher than that in the movie mode.
