CAM-BASED HDR COLOR AND TONE REPRODUCTION FOR ENHANCED STEREOSCOPIC DISPLAY VIEWING

Brightness degradation occurs in almost all stereoscopic displays (three-dimensional (3D) displays). When the brightness of the display is lowered in 3D mode, the lightness, hue, and chrorna of the color attributes are the same, but the colorfulness becomes lower than in the two-dimensional (2D) mode. In this paper, we propose a color appearance model-based (CAM-based) high dynamic range (HDR) color and tone reproduction method that compensates for the loss of colorfulness and the change of visual contrast due to the brightness reduc-tion of the 3D display. As a result of applying the proposed method, it is con-firmed that an HDR, image is reproduced in 3D mode, the tone mapping is pro-cessed appropriately in 3D viewing condition and the colorfulness is improved to that of 2D mode.
