Color reproduction using intensity compensation function for dual camera systems
Vivek Maik, Soohwan Yu, Seungyong Ko, Joonki Paik · 2016
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.
