Abstract
An image display device includes a light source that emits a light beam, a screen, a scanning section that scans the screen with the light beam, an optical system, a drive section, and a screen drive circuit. The optical system generates a virtual image by using the light beam that has passed through the screen. The drive section moves the screen at least in parallel to a travel direction of the light beam. The screen drive circuit contains a drive signal table that stores an information group for use in generating a drive signal tailored to stop the screen at different stop locations over different stop periods. The screen drive circuit selects first information in the drive signal table which is associated with displaying of an image and supplies the drive section with a first drive signal generated from the first information.
