Abstract
The number of images to be composited used to generate a dynamic range-extended image, and exposure conditions for respective images to be composited are determined. A proper exposure condition is determined for a subject corresponding to a moving object region, and one of the exposure conditions of the images to be composited is changed to the proper exposure condition. An image capture apparatus specifies a moving object region for a plurality of images to be composited, which are captured under the exposure conditions of the images to be composited including the proper exposure condition. A dynamic range-extended image is generated using pixels of the image to be composited, which is captured under the proper exposure condition, as those of the moving object region, which is specified for the plurality of images to be composited.
