Abstract
An image sensing apparatus obtains the weighted average luminance of an image sensing target that puts weight on a main subject in an obtained luminance distribution of the image sensing target. The image sensing apparatus decides exposure control values based on the average luminance of a region that is lower than the weighted average luminance, out of regions each of a predetermined size contained in the image sensing target, and the weighted average luminance.
