Television pick-up and display system, and television pick-up device and optical system suitable for use in such a system

摘要

In a television pick-up and display system comprising a pick-up device having an image pick-up face whose aspect ratio deviates from an aspect ratio of the image display face of the image display device, the pick-up device can be rendered suitable for cooperation with the image display device by insertion of an anamorphotic optical system between an object plane and the image pick-up face. When use is made of an image pick-up face having a 4:3 aspect ratio and an image display face having a 16:9 aspect ratio, the anamorphotic optical system compresses an image of the object plane in the horizontal direction by a compression factor amounting to 0.75. When the compressed image of the image pick-up face is displayed, an image-filling, non-distorted image is obtained on the image display face.
