Abstract

A wide dynamic range camera for high picture quality use is proposed. The camera is equipped with a novel optical beam splitting system. It first divides incident light into two different intensity lights. Small intensity light is taken by a single-chip color imager. The other large intensity light is further led to a tri-color prism and taken by three imagers. These functions are integrated into one-piece optical block, which is suited for 2/3-inch optical format standard. An experimental HDTV camera has been developed. The exposure ratio was set as 9:1. A high exposure image is taken by three 2M-pixel CCDs and a low exposure image is taken by a single-chip color 2M-pixel CCD with an on-chip stripe color filter. The results have shown that the validity of the proposed method for obtaining wide dynamic range images with high picture quality.
