Abstract
An image capture device provided with a first memory unit, which memorizes position information of non-continuous defective pixels of a solid-state image capture component, and a second memory unit with a higher access rate than the first memory unit, which memorizes position information of continuous defective pixels. When a continuous photography mode or a video photography mode is set, defective pixel correction processing is carried out on image data corresponding to each of defective pixels according to the defective pixel position information stored at the second memory unit. Alternatively, when a still photography mode is set, image data corresponding to all defective pixels is corrected, based on both the defective pixel position information stored at the first memory unit and the defective pixel position information stored at the second memory unit. As a result, it is possible to correct defective pixels with high efficiency in accordance with conditions of photography.
