Abstract
Abstract A spectacles frame image picked up by a TV camera is displayed on a TV monitor, and pattern data representing a frame and its image data are recorded in a spectacles frame data-base by setting an image region to be cut out using a cursor. At this time, a process for removing an enhancement region and a digitized process for obtaining pattern data are performed by a processor. After a spectacles frame data-base is created, in the processor an image of a human face and the frame image can be synthesized by edge processing and color mixing processing.
