PROBLEM TO BE SOLVED: To provide a three-dimensional image plotting device making it possible to introduce pixel information accompanying transparency information and depth information of a pixel as plural three-dimensional image plotting information and obtain picture quality improving reality and an information holding medium used for operation of this device. SOLUTION: The pixel information (RGB)a (RGB)b accompanying luminance, the transparency informationαa,αb and the depth information Za, Zb are outputted from three-dimensional image plotting parts A, B. The depth information Za, Zb outputted while synchronizing with the pixel information (RGB)a, (RGB)b are judged by a priority selection part 2a which one exists in front, and the synthetic ratio selection 2c of the transparency of the both pixel information is performed based on the result. After adjusting attenuation answering to a synthetic ratio, the both pixel information are synthesized to be outputted as a synthetic image RGB. For instance, a video of a signal existing in the background in the depth direction is synthesized with the transparency of the signal existing in the foreground. |
