摘要： 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.

摘要： An image processing method is provided. An image signal is received and correspondingly converted to an original luminance value, an original first chroma value and an original second chroma value. The original luminance value is adjusted to a modulated luminance value. The modulated luminance value is larger than the original luminance value as the original luminance value is larger than a threshold. The modulated luminance value is less than the original luminance value as the original luminance value is less than the threshold. The original first and second chroma values are linearly adjusted to a modulated first chroma value and a modulated second chroma value according to an original vector between the original first and second chroma values and a white point in a color gamut. The modulated luminance value, the modulated first chroma value and the modulated second chroma value are reconverted to a modulated image signal.
