US 5,144,445 A · Solid-state image pickup apparatus having a plurality of photoelectric transducers arranged in a matrix

Abstract

A video signal obtained by a solid-state image pickup device is supplied to a display apparatus to display an image. The number of the pixels of the solid-state image pickup device is smaller (e.g., 1/4) than that of the screen of the display apparatus. The transfer clock of the solid-state image pickup device is so controlled that the video signal output therefrom corresponds to an image displayed at the region of 1/4 of the reproducing screen. The video signals from four solid-state image pickup devices are compounded so as to display an image composed of four divided images on one screen. A synchronizing signal which is a reference for the transfer clock is transmitted from the display apparatus so as to synchronize the four video signals. In another mode, the transfer clock is so controlled as to enlarge a video signal which corresponds to an image for the 1/4 region of the reproducing signal and display the image on the entire part of the reproducing screen.
