Abstract

A normalized tone-mapping method that can reproduce a 3DTV image with an improved color sensation is proposed. This method uses 128 levels of gray-scale images to measure the RGB tone-curves in both 2D and 3D modes and then models the curves using a piece-wise linear form. To compensate the difference between these two tone-curve models, tone-mapping operators are generated. In addition, the tone-mapping operators are normalized to reduce distortions in the color contrast. Experimental results show an 8.49dB improvement of image quality as compared with a conventional 3DTV.
