Abstract
A super-resolution processing portion has a high-resolution image generation portion that fuses a plurality of first input images together to generate a high-resolution image. The first input images are shot at a shutter speed equal to or faster than the super-resolution limit shutter speed, which is the lower-limit shutter speed that enables super-resolution processing to make the resolution of the output image equal to or higher than that of the input images. According to the amount of exposure, one of the following different methods for super-resolution processing is selected: a first method that yields as the output image the high-resolution image; a second method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on an averaged image; and a third method that yields as the output image a weighted added image resulting from weighted addition of the high-resolution image and an image based on a second input image.
