Abstract: A digital photographing device may include a plurality of cameras on a common side of the device, an application processor for switching image capture between the camera, and a display. The application processor may switch images output on the display when the cameras are switched. During the image transition, one or more virtual viewpoint images are output between a pre-transition image and a post-transition image. The virtual viewpoint images interpolate a disparity between the pre-transition image and the post-transition image caused by the different cameras being located at different positions, and result in a smooth visual transition. When a camera switching input includes a zoom factor signal, the virtual viewpoint images may be compensated images according to the input zoom factor and a disparity.
