A stereoscopic image generation device that generates a stereoscopic image including a right-eye image and a left-eye image is provided. The stereoscopic image generation device includes an image enlarging/reducing unit that enlarges or reduces the right-eye image and the left-eye image which constitute stereoscopic image data, and a display control unit that performs control to display a stereoscopic image by showing the right-eye image and the left-eye image of the stereoscopic image data for a right eye and a left eye, respectively. The image enlarging/reducing unit enlarges or reduces the right-eye image and the left-eye image on the basis of parallax amount adjustment information, which includes a position of a right-eye-image reference point and a position of a left-eye-image reference point which are respectively provided at different positions for the right-eye image and the left-eye image, and enlargement ratios of the right-eye image and the left-eye image, with reference to the right-eye-image reference point and the left-eye-image reference point. Accordingly, a position in the depth direction can be easily controlled while adjusting a parallax.

Stereoscopic image generation device, stereoscopic image display device, stereoscopic image adjustment method, program for causing computer to execute stereoscopic image adjustment method, and recording medium on which the program is recorded

To generate an image that enables effective suppression of the occurrence of binocular rivalry and that facilitates stereoscopic vision. A left-eye image feature point extraction unit () and a right-eye image feature point extraction unit () extract feature points from a left-eye image and a right-eye image, respectively. A number-of-non-corresponding-points calculation unit () calculates, in a case where the feature points in one image among the left-eye image and the right-eye image, which are extracted by a left-eye image feature point extraction unit () and a right-eye image feature point extraction unit (), are shifted a certain distance in the horizontal direction, the number of feature points in the one image that do not correspond to the feature points in the other image, for each shift distance. A disparity value adjustment unit () adjusts a disparity value between the left-eye image and the right-eye image in accordance with the number calculated for each shift distance.
