Abstract

This paper describes a new high dynamic range (HDR) image capture system that utilizes an electrochromic display (ECD). The ECD panel reduces the transmittance of bright area and increases the transmittance of dark area, which retain as much information as possible without saturation at high or low luminance. A passive matrix driving scheme is employed for the ECD due to low cost and high transmittance and the column and row driving voltages are obtained by least square error method. The resulting information gain defined as the maximum gray scale ratio of HDR and normal images is 1.73.
