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 apparatus and an image processing method. The image processing apparatus includes a first convolution unit, a weight generator, a second convolution unit, an arithmetic unit and an outputting unit. The first convolution unit performs a convolution to output edge strength according to an original image signal and a high pass filter mask. The weight generator chooses a weight coefficient according to the edge strength. The second convolution unit performs a convolution to output an unsharp image signal according to the original image signal and a low pass filter mask. The arithmetic unit outputs a first sharpening signal according to the original image signal, the unsharp image signal and the weight coefficient. The outputting unit outputs a processed image signal according to the original image signal and the first sharpening signal.

摘要： An image data conversion method is provided. The method comprises the following steps of (a) receiving an original image data having three basic-color sub-pixel data and (b) calculating at least one color-enhancing sub-pixel data according to any two basic-color sub-pixel data so as to convert the original image data into an image data having at least three basic-color sub-pixel data and one color-enhancing sub-pixel data. The calculation of the color-enhancing sub-pixel data is represented as: J i = [ var . - (  D i - E i  S ) ] × Max  ( D i , E i ) wherein 0.8
