<P>PROBLEM TO BE SOLVED: To reduce a tired feeling and an unpleasant feeling of a user who performs stereoscopic viewing when a three-dimensionally displayed image is digitally zoomed in a three-dimensional display device. <P>SOLUTION: The three-dimensional display device includes a display unit for carrying-out three-dimensional display based on a plurality of two-dimensional images having parallax, and a digital zoom unit for respectively digitally zooming the two-dimensional images. A digital zoom rate of two-dimensional images zoomed by the digital zoom unit is obtained. When the obtained digital zoom rate is larger than 100%, at least one of the digitally zoomed two-dimensional images is modified based on an enlarged amount of parallax so that an amount of parallax between the digitally zoomed two-dimensional images becomes the enlarged amount of parallax. The enlarged amount of parallax is obtained by enlarging an amount of parallax between the two-dimensional images before being digitally zoomed at a moderated digital zoom rate, and the moderated digital zoom rate is obtained by moderating the digital zoom rate at a moderation rate, where the moderation rate increases as the zoom rate increases. Then, a display unit is caused to carry out three-dimensional display based on the modified two-dimensional images. <P>COPYRIGHT: (C)2011,JPO&INPIT |
