Abstract
A saturation adjusting apparatus for processing a pixel, which has three color components each having a value falling within a range defined by upper and lower extreme values, of a RGB color model includes an extreme value controller and a component adjuster. The extreme value controller determines maximum and minimum extreme value thresholds for ensuring that the values of the color components of the pixel after undergoing linear color correction processing based on a correction indicator fall within the range defined by the upper and lower extreme values. The component adjuster includes a decision-making unit for choosing the correction indicator from a group of values which includes the maximum extreme value threshold, the minimum extreme value threshold, and a saturation setting. The component adjuster further includes a color corrector for performing linear color correction processing on the three color components of the pixel using the correction indicator.
