ABSTRACT:
An image processing method for individually processing an image of each pixel unit is provided. A red-green-blue color space signal to be input to a pixel unit is transformed into a first brightness signal. The red-green-blue color space signal includes a first red signal, a first green signal and a first blue signal. The first brightness signal is transformed into a second brightness signal to obtain a contrast factor, wherein the contrast factor is a ratio of the second brightness signal and the first brightness signal. The first red signal, the first green signal and the first blue signal are multiplied by the contrast factor to obtain a second red signal, a second green signal and a second blue signal. The second red signal, the second green signal and the second blue signal are performed by color enhancement to obtain a high contrast and colorful image.
