US Patent 9060170 Image display device and method, as well as program

A stereoscopic imaging apparatus includes a photographing device for obtaining two images through photographing from different positions, a three-dimensional processing device for generating a stereoscopic image from the two images, a display device capable of both a two-dimensional display and a stereoscopic display, an input device for receiving an instruction to start changing a parallax level of the stereoscopic image and an instruction to change the parallax level, and a display control device for changing stereoscopic display of the stereoscopic image into two-dimensional display of the two images overlapped with each other in a response to the instruction to start changing the parallax level inputted when the stereoscopic image is stereoscopically displayed as a live view image, and two-dimensionally displaying the two images with changing the parallax level of the images in a response to the instruction to change the parallax level.
