A game devicedisplays an image on an upper LCDcapable of producing stereoscopic display using two images. Based on two captured images of a predetermined image-capture object captured respectively by two image-capturing devices, the game devicecalculates a positional relationship between the predetermined image-capture object and each of the image-capturing devices. Then, the game devicedetermines a zero-parallax distance using at least one of the positional relationships so that it is a distance in accordance with a distance from the image-capturing device to the image-capture object, and determines display positions of the two captured images to be displayed on the upper LCDin accordance with the zero-parallax distance. Moreover, the game deviceproduces two virtual images based on two virtual cameras which have been set using the positional relationships, and produces a synthesized image obtained by synthesizing the virtual image with the captured image to display the image on the upper LCD

First, a stereoscopic vision reference distances is individually determined for each virtual object disposed in a virtual space, based on a depth position of each of the virtual objects. Next, each of the virtual objects is rendered and combined based on one pair of virtual cameras such that a relative position, with respect to the screen of a stereoscopic display device, of a virtual object, viewed by a user through a screen of the stereoscopic display device, matches a relative position of the virtual object with respect to a stereoscopic vision reference surface for the virtual object in the virtual space.

Computer-readable storage medium, image display apparatus, system, and method

An example game device sets a reference distance for a distance from a real camera in an image-capturing direction, and displays a right captured image and a left captured image in a display area so that a reference point, which is a point that is away from the real camera by the reference distance, is displayed at a center in the display area. Thus, when an image produced by using an augmented reality technique is stereoscopically displayed, it is possible to display a virtual image in a manner easy to view.

A game devicecalculates, for each of two real cameras, position/orientation information representing a relative position and orientation with respect to a predetermined image-capture object, and based on this calculates a camera interval in the predetermined coordinate system. Then, it calculates correspondence information between a unit length in the predetermined coordinate system and a unit length in a real space by using the calculated distance in the predetermined coordinate system and the camera interval in the real world.

A game devicedisplays an image on an upper LCDcapable of producing stereoscopic display using two images. The game devicedetermines a shift amount from a reference position for a frameof a predetermined size representing a display area of each captured image. Here, for at least one of the frames, if the framemoved by the shift amount protrudes out of a captured image, the size of each frame is changed so that the framedoes not protrude out of the captured image. The game devicedisplays an image in the frame of each of two captured images in a predetermined area on a screen of a stereoscopic display device.
