Abstract
An image sensing apparatus is constructed in such a manner that a calculation priority setter 5111 (5111a) sets a priority between exposure amount control by an exposure amount control parameter calculator 511 (511a) serving as exposure amount controller, and dynamic range control by a dynamic range control parameter calculator 512 (512a) serving as dynamic range controller. Exposure control is executed by performing the exposure amount control and the dynamic range control based on a photoelectric conversion characteristic, by using exposure evaluation values detected by an evaluation value detector 405, based on the priority set by the calculation priority setter 5111 (5111a). This arrangement provides an image sensing apparatus capable of performing exposure control with high latitude, wherein a user is allowed to capture a subject in an optimal exposure state, with an appropriate dynamic range being secured, and control primarily based on the exposure amount control or control primarily based on the dynamic range control is performed on the priority basis.
