VIEW FINDER SYSTEM FOR THREE DIMENSIONAL IMAGE

摘要

PURPOSE: A view finder system for a three dimensional image is provided to recognize an object easily and align easily a biprism to a video camera in a single lens stereo camera. CONSTITUTION: An image signal input unit(34) is a frame grabber in relation to an analog signal and an interface circuit in relation to a digital signal. An image analysis device(38) is an electronic circuit including a decoder dedicated chip for analyzing a video signal such as NTSC or PAL and converting it into an image in a memory buffer. An image composition device(37) superposes transparently images corresponding to a right and a left image in the image of the memory buffer. An image change device(36) changes an image included in a specific color memory buffer into an image which meets with a characteristic of an image display device(35).
