A system of the present disclosure comprises a shooting system and a playback system. The shooting system includes first and second shooting sections and a disparity calculating section that generates a differential image representing a difference between first and second images that have been shot by the first and second shooting sections, respectively. The playback system includes an image generating section that generates, based on the differential image and the first image, a third image that has as high a resolution as the first image and that forms, along with the first image, a 3D image. The image generating section generates, based on the first image and the differential image, a depth map representing the amount of parallax between the first and second images, and generates the third image based on the first image and the depth map.
