<p>PURPOSE:To input visual point information by a simple operation at the time of displaying a three-dimensional video. CONSTITUTION:A rotation amount detecting means for detecting rotational amount around respective three-dimensional coordinate axes and a moving amount detecting means for detecting the moving amount of an operation part 3 in a two-dimensional direction are provided in the operation part 3. An image display controller main body 12 changes the display data of an image display part 13 in accordance with the operation of the operation part 3. When an operator rotates the operation part 3 in a prescribed direction in air or moves it on a table or the like in horizontal direction, a displayed image is rotated or moved in parallel in a screen.</p> |
