PURPOSE:To perform the selection display for a three-dimensional image in a short time by installing a frame buffer memory which memorizes a plurality of three-dimensional image display data and a three-dimensional image selecting part which selects one data for the display on a display part, from among a plurality of three-dimensional image display data. CONSTITUTION:The display data which can display a three-dimensional image is stocked in a frame buffer memory 28. A three-dimensional image selection part 30 freely selects one among a plurality of three-dimensional image display data in the frame buffer memory 28 by providing the output data at a specific address by a central control unit 24, and can be sent into a D/A converter 32. In the D/A converter, the inputted display data is converted to the analogue signals, and a display part CRT 34 displays the three-dimensional image according to the converted display data. Such the selection of images can be carried out instantly, and the need of waiting for the calculation processing for each image display as in the conventional is obviated. |
