Abstract:
An image sensing apparatus that carries out image sensing continuously and inputs a plurality of images, having a digital signal processing circuit that detects, at each input image, from image data thereof, an object that satisfies a preset condition, a first exposure value determination unit that calculates a first exposure value from the image data, a second exposure value determination unit that calculates a second exposure value based on the detected object, and a selection unit that selects either the first exposure value, the second exposure value, a currently set exposure value, or an exposure value calculated based on a luminance of an area referenced when calculating a currently set exposure value as an exposure value to be used for a next image sensing based on object detection results obtained by the digital signal processing circuit.
