Paper Abstract

Picture adjustment is referred to those adjustments that affect the four main subjective perceptual image attributes: Hue, Saturation, Brightness (sometimes called Intensity) and Contrast--HSIC adjustments. The common method used for this type of adjustments in a display processing pipe is based on YCbCr color space and a 3x4 color adjustment matrix. Picture adjustments based on this method, however, leads to multiple problems such as adjusting one attribute leads to degradation of other attributes. As an alternative, other color spaces such as HSV can be used to generate more consistent and effective picture adjustments. In this paper, the results of a comparative performance analysis between the two methods based on YCbCr and HSV color spaces (for HSIC adjustments) are presented.
