Abstract

An image sensing apparatus comprises: a pixel array; a selection unit which selects a readout region in the pixel array; and a readout unit which reads out a signal from the readout region, wherein in thinning-out readout, the readout unit reads out signals from a first readout region corresponding to the whole pixel array at a first pixel density in a first frame period and reads out signals from a second readout region corresponding to a part of the pixel array at a second pixel density in a second frame period, the second pixel density being higher than the first pixel density, and in thinning-out readout, the selection unit causes pixels in the first readout region to perform a charge accumulation operation for a first accumulation period and causes pixels in the second readout region to perform the charge accumulation operation for a second accumulation period.
