1. A method for eyewear simulation, wherein a spectacles frame is matched with a person, said method comprising: projecting a reference area on a display device; aligning an image of a person who has taken off his/her spectacles taken with a video camera on said display device with said reference area; converting analog signals from said camera to digital signals representing the aligned image of the person by an A/D-conversion, storing into a video memory device the converted digital signals; thereafter displaying the aligned image which is 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 displaying the person with the spectacles frame superimposed on his/her face on a display device to thereby match the spectacles with the person.
