Paper Abstract

Different kinds of color models were tested in typical monitor image manipulation applications. considerable attention was paid to different ways of adjusting the tone rendering (or luminance component) of color images. Other image manipulation measures, such as the adjustment of grey balance and saturation, were also discussed. The color models studied included RGB, HSV, HLS and CIELUV color co-ordinate systems, and the new Ls(alpha) space, which was developed specifically for image manipulation purposes. In the tone rendering adjustment tests, the color co-ordinate systems were primarily assessed according to how ell they allowed free manipulation of brightness without affecting other components of color (i.e. hue and saturation). In these visual tests, the L component of the Ls(alpha) color space proved to be the most suitable co-ordinate for adjustment with a tone rendering curve.
