A digital still camera includes an image-capturing device, a recording device that records a subject image captured by the image-capturing device into an image recording medium, a first monitor device and a second monitor device. The images repeatedly captured by the image-capturing device are displayed in real time at the first monitor device and, at the same time, a photographic support image having been captured by the image-capturing device is displayed at the second monitor device. A single image or a plurality of images recorded in the image recording medium, for instance, may be displayed at the second monitor device as the photographic support image. Alternatively, an image obtained by partially enlarging the image displayed at the first monitor device may be displayed at the second monitor device.
