Abstract
An image capturing apparatus comprises an image sensing element including an effective pixel portion, and a shading pixel portion; a setting unit which variably sets, in at least one of row and column directions, an effective pixel signal readout region and shading pixel signal readout region; a readout unit which reads out the effective pixel signals and reads out the shading pixel signals; a correction data generation unit which generates correction data for each column or each row; a correction unit which corrects luminance levels of the effective pixel signals, for each column or each row; and a control unit which controls the setting unit so that the shading pixel signal readout region becomes wider than the effective pixel signal readout region.
