Material exhibiting apparatus

摘要

A material exhibiting apparatus displays an image of a material and a character such as an arrow on a display screen in an overlapped state. A location of a display area is set in synchronization with horizontal and vertical synchronizing signals. The set location of the display area is changed by varying a generation timing of either one or both of the horizontal and vertical synchronizing signals. A display location of the character is changed by changing the set location of the display area. Since the display location of the character is quickly changed on the basis of frequencies of the horizontal and vertical synchronizing signals, the movement of the character can continuously be displayed on the display screen.
