Abstract: A digital camera that includes an imaging sensor having a stop 2 arranged in front of an imaging surface includes an imaging control unit that starts exposure of pixels on the entire imaging surface at the same time and then, ends the exposure of the pixels at the same time in a state where light from a subject is incident on the imaging surface, by controlling an imaging sensor drive circuit which drives the imaging sensor, and a processor that sequentially changes an F number of the stop 2 to a plurality of values during a period from the start of the exposure until the end of the exposure. The processor controls a time in which the F number is maintained at each of the plurality of values to be a time that is based on a function indicating light transmittance characteristics of an APD filter.

Abstract: An imaging element incorporates a reading portion, a storage portion, a processing portion, and an output portion. The reading portion reads out image data obtained by imaging from a photoelectric conversion element at a first frame rate. The storage portion stores the image data read out from the photoelectric conversion element. The processing portion processes the image data. The output portion outputs the image data processed by the processing portion at a second frame rate. The processing portion detects first image data indicating a specific image from the image data stored in the storage portion. The output portion outputs second image data based on image data different from the first image data detected by the processing portion in the image data of a plurality of frames. The second frame rate is a frame rate lower than the first frame rate.
