Patent ID: 8077968

Claim:
An image processing method, for individually processing an image of each pixel unit, comprising: transforming a red-green-blue color space signal for a pixel unit into a first brightness value, wherein the red-green-blue color space signal comprises a first red value, a first green value and a first blue value; transforming the first brightness value into a second brightness value to obtain a contrast factor, wherein the contrast factor is a ratio of the second brightness value and the first brightness value; respectively multiplying the first red value, the first green value and the first blue value by the contrast factor to obtain a second red value, a second green value and a second blue value; transforming a maximum difference among the first red value, the first green value and the first blue value into a color enhancement factor; obtaining a first formula, a second formula and a third formula based on the color enhancement factor; and respectively inputting the second red value, the second green value and the second blue value to the first formula, the second formula and the third formula to obtain an output red value, an output green value and an output blue value.
