Image display device
Abstract:
An image display device includes a light source, a screen, an optical system, a screen driving mechanism unit, a memory unit, and a screen driving circuit unit. An image is formed on the screen by being irradiated with light from the light source. The screen driving mechanism unit moves the screen in an optical axis direction of the light. A smoothed movement profile is obtained by smoothing a movement profile used as a target for moving the screen so as to make a moving speed of the screen vary gently. The memory unit stores screen driving waveform information that has been generated so that the screen follows the smoothed movement profile. The screen driving circuit unit drives the screen driving mechanism unit, based on the screen driving waveform information stored in the memory unit.
