Claim One:
1. An image capture apparatus for generating a dynamic range-extended image by compositing a plurality of images to be composited, comprising: an image capture unit configured to output an image obtained by capturing a subject; a determination unit configured to determine the number of images to be composited used to generate a dynamic range-extended image, and exposure conditions for the respective images to be composited from a distribution of pixel values of the subject; a first specifying unit configured to specify a moving object region for a plurality of pre-shot images output from said image capture unit; a change unit configured to determine a proper exposure condition for a subject corresponding to the moving object region specified by said first specifying unit, and to change one exposure condition of the exposure conditions of the images to be composited determined by said determination unit to the proper exposure condition; a second specifying unit configured to specify a moving object region for the plurality of images to be composited, which are captured by said image capture unit under the exposure conditions of the images to be composited including the proper exposure condition; and a generation unit configured to generate the dynamic range-extended image by compositing the plurality of images to be composited, said generation unit using pixels of the image to be composited captured under the proper exposure condition as pixels of the moving object region specified by said second specifying unit.
