Claim Text:
1. A method for adjusting saturation degree, comprising: dividing a hue circle into a plurality of hue regions, and dividing each of the hue regions into a plurality of saturation regions according to at least one saturation threshold; weighting a plurality of first input saturation degrees of a first saturation region of a first hue region of the hue regions by a first weighting formula for obtaining a plurality of first output saturation degrees; and weighting a plurality of second input saturation degrees of a second saturation region of the first hue region of the hue regions by a second weighting formula for obtaining a plurality of second output saturation degrees, wherein the first weighting formula is different from the second weighting formula, and the saturation threshold of each of the hue regions is Sth, RGBmax is a maximum value among trichromatic component values of a plurality of input image signals within the hue region, and RGBmin a minimum value among the trichromatic component values of the input image signals within the hue region.
