Color reproduction using intensity compensation function for dual camera systems

This paper presents the color reproduction method for dual camera system. The proposed method uses the input images acquired in different exposure conditions. The brightness of short-exposure image is restored using conventional haze removal-based low-light image enhancement method. Next, the color components of the brightness enhanced image are restored using the weight map, which is computed between the luminance channels of long- and enhanced short-exposure image. Experimental results show that the proposed color reproduction method can provide the color reproduction result using the dual camera system without the color distortion and brightness saturation.
