PURPOSE: To provide an image controller which gives vanishing effects that make an image on an optional display surface vanish gradually from a translucent state without altering the device constitution. CONSTITUTION: A selector 80 separates plural display surfaces supplied from generator parts 42-44 by anαsystem and aβsystem and a controller 61 superposes them for every system according to a specified priority to form display screens. A CLT 62 converts the display screens of the systems into display data showing colors of pixel units. An arithmetic part 75 adds the display data of theαandβsystems together to generate a translucent display screen. A rear-part arithmetic part 77 adds the translucent display screen outputted by the arithmetic part 75 to color data (specific color) read out of a register 76. When a CPU increases the color data value in the register 76 gradually, the display screen vanishes with the specific color. |
