A computer-readable storage medium having stored therein a stereoscopic image display program to be 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 captured images captured by two image-capturing devices (23a, 23b), wherein the stereoscopic image display program instructs the computer to function as: a shift amount determination section (311, S21) for determining a shift amount from a reference position for adjusting parallax in stereoscopic display for an area of a predetermined size representing a display range of each captured image; an area size changing section (311, S23) wherein for at least one of the areas, if the area moved by the shift amount protrudes out of the captured image, the area size changing section changes the size of the area so that the area does not protrude out of the captured image; a display control section (311, S7) for displaying an image in a display object area of each of the two captured images in a predetermined area on a screen of the stereoscopic display device, wherein the display object area is the area determined by the shift amount determination section and the area size changing section; the shift amount determination section (311, S21) successively determines a shift amount for a predetermined captured image to be displayed on the stereoscopic display device among captured images successively obtained in real time from the two image-capturing devices, wherein the determination is made on the basis of a zero-parallax distance corresponding to a distance from the image-capturing device to a predetermined image-capture object; each time the shift amount is determined for the predetermined captured image, the area size changing section determines whether an area moved by the shift amount protrudes out of the captured image, and changes a size of the area if the area protrudes out of the captured image; and the display control section (311, S7) successively displays an image in each display object area of the predetermined captured image in the predetermined area on the screen of the stereoscopic display device. a shift amount determination section (311, S21) for determining a shift amount from a reference position for adjusting parallax in stereoscopic display for an area of a predetermined size representing a display range of each captured image; an area size changing section (311, S23) wherein for at least one of the areas, if the area moved by the shift amount protrudes out of the captured image, the area size changing section changes the size of the area so that the area does not protrude out of the captured image; a display control section (311, S7) for displaying an image in a display object area of each of the two captured images in a predetermined area on a screen of the stereoscopic display device, wherein the display object area is the area determined by the shift amount determination section and the area size changing section; the shift amount determination section (311, S21) successively determines a shift amount for a predetermined captured image to be displayed on the stereoscopic display device among captured images successively obtained in real time from the two image-capturing devices, wherein the determination is made on the basis of a zero-parallax distance corresponding to a distance from the image-capturing device to a predetermined image-capture object; each time the shift amount is determined for the predetermined captured image, the area size changing section determines whether an area moved by the shift amount protrudes out of the captured image, and changes a size of the area if the area protrudes out of the captured image; and the display control section (311, S7) successively displays an image in each display object area of the predetermined captured image in the predetermined area on the screen of the stereoscopic display device.
