Abstract
An image of a person who has taken off his/her spectacles is taken on a video camera; then video signals for the image of the person are A/D-converted and stored into a video memory device as the digital signals; thereafter display signals are produced by synthesizing data for the image of the person and data for the spectacles frame as stored in the video memory device; and finally a state of the person with the spectacles frame being put on his/her face is displayed on a display device to thereby match the spectacles with the person.
