ABSTRACT:
An image sensing apparatus that controls exposure includes a signal processing unit for processing the output signal of a image sensing element, an aperture control unit for controlling aperture, and an external sensor for measuring the brightness of an object. In this case, exposure is controlled using the luminance information of both the image data and the external sensor, with the sampling period of the external sensor being set to be shorter than the accumulation period of the solid-state image sensing element. At least one of the aperture and the accumulation period is then controlled, based on the luminance information measured by the external sensor during the accumulation period.
