<p>A translucent-image display apparatus and method performs a process for displaying a translucent image. In the process, lower image data to be displayed on a screen, and upper image data to be displayed on the lower image are read. Color-palette data of the lower image and color-palette data of the upper image are read. Achromatic data having a brightness level identical to the brightness level of each color included in the color-palette data of the upper image are read. A superposing range in which the upper image is superposed on the lower image is defined based on the lower image data and the upper image data. First composite color data are generated by subtracting the color represented by the achromatic data from the color of the lower image in the superposing range, based on the color-palette data of the lower image and the achromatic data. Second composite color data are generated by adding the color represented by the color-palette data of the upper image to the first composite color data. And, the upper image is translucently displayed in the second composite color on the screen, based on the second composite color data. In the translucent-image display apparatus and method, a pre-recorded and computer-readable storage medium is used. <IMAGE></p> |
