Storage medium having stored therein stereoscopic image display program, stereoscopic image display device, stereoscopic image display system, and stereoscopic image display method

摘要

A game device 10 displays an image on an upper LCD 22 capable 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 device 10 calculates a positional relationship between the predetermined image-capture object and each of the image-capturing devices. Then, the game device 10 determines 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 LCD 22 in accordance with the zero-parallax distance. Moreover, the game device 10 produces 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 22.

1. A non-transitory computer-readable storage medium having stored therein a stereoscopic image display program, which when executed by a computer of an information processing device which displays an image on a stereoscopic display device capable of producing stereoscopic display using two images, causes the information processing device to at least:
obtain two captured images of a predetermined image-capture object in a real space, captured respectively by two image-capturing devices; calculate respective positional relationships between the predetermined image-capture object and each of the image-capturing devices based on the two captured images; determine a zero-parallax distance using at least one of the positional relationships, wherein the zero-parallax distance corresponds to a distance, in a virtual space image-capturing direction, from at least one of two virtual cameras to a point in a virtual space that appears to be present at a position of a screen of the stereoscopic display device in stereoscopic display or a distance, in a real space image-capturing direction, from the image-capturing device associated with the used positional relationship to a point in the real space that appears to be present at the position of the screen of the stereoscopic display device in stereoscopic display; determine respective display positions of the two captured images to be displayed on the stereoscopic display device so that a display object present at a position in accordance with the zero-parallax distance appears to be present at the position of the screen of the stereoscopic display device in stereoscopic display; set each of the two virtual cameras for producing a respective virtual image representing an object in the virtual space by using a corresponding one of the positional relationships so that a range of the virtual space represented by the respective virtual image and a range of the real space represented by a corresponding captured image coincide with each other, and producing two virtual images based on the two virtual cameras which have been set; and perform, for each captured image, a process of producing a synthesized image for display on the stereoscopic display device, each synthesized image obtained by synthesizing one of the virtual images with the corresponding captured image.
