Abstract:
1. An image display device comprising: a display unit capable of stereoscopically displaying a stereoscopic image generated from more than one images taken from different points of view; an input unit for receiving an instruction to control a stereoscopic effect of the stereoscopic image while the stereoscopic image is stereoscopically displayed by the display unit; a three-dimensional processing unit for applying three-dimensional processing for stereoscopic display to the more than one images to generate the stereoscopic image, the three-dimensional processing being applied to achieve a stereoscopic effect according to the instruction; and a recording control unit for recording, in a recording unit, control values of the stereoscopic effect according to the instruction, the control values being associated with the more than one images, wherein, if there are the control values of the stereoscopic effect recorded in the recording unit, the recording control unit records, in the recording unit, difference values between the control values of the stereoscopic effect according to the instruction and the recorded control values of the stereoscopic effect, wherein, according to the instruction to control the stereoscopic effect, the display unit trims an area proportional to an aspect ratio identical to that of each of the more than one images from an overlapping range between the more than one images in the stereoscopic image, and displays the stereoscopic image with adding a frame indicating the trimmed area around the stereoscopic image with respect to the trimmed area, wherein, in a case where the control values of the stereoscopic effect comprises a parallax level between the more than one images, the display unit changes a color of the frame stepwise depending on the parallax level.
