Problems solved by technology

The original input image contains information of three primary colors of R, G, and B, but after ASIC image processing and interpolation calculation, each pixel of the LCD can only display one of R, G, or B colors, and cannot The information of three primary colors is displayed in the same pixel at the same time. Therefore, when the image contains lines or at the edge of the image, each pixel that the line or edge passes can only display a single color, resulting in aliasing of the lines and image edges. problem; in addition, when the image is enlarged, since each pixel can only display a single color, the resolution of the image is also deteriorated and it is easy to be distorted

Embodiment Construction

[0028] The image display color processing method of the present invention can be implemented by hardware or software, and the method enables the pixel array in a display to present better image quality performance. As shown in Fig. 1, the display that the present invention is applied is generally the display that delta arranges, and the pixel array 10 in it is made up of a plurality of pixels 12, and wherein odd column (row) pixel (1st, 3rd...column) Translate 1 / 2 pixel pitch (pixel pitch) relative to the pixels in even columns (rows) (columns 0, 2...) (actually there is no such displacement). The processing method of image display color of the present invention comprises the following steps: first, as shown in Figure 2, captures an image file 20 to be processed, this image file 20 is made up of a plurality of image pixels 22, and the color of each image pixel 22 The value includes three components of red (R), green (G) and blue (B); then all the image pixels 22 of the image f...

Abstract

This invention provides a process method for an image color display. When computing colors displayed by pixels, it displays every pixel of the even array and add array and consults multiple image pixels to provide more color information further to show the computed result by pixel array of a display.

Description

technical field [0001] The invention relates to a method for processing image display colors, in particular to a method for improving the false color of display images, so that the displayed colors are closer to the original input image colors. Background technique [0002] With the popularity of audio-visual multimedia and the successive introduction of digital imaging equipment, users have increasingly strict requirements on image color, and the status of image displays is becoming increasingly important. Image displays usually have built-in application specific integrated circuits (ASICs). , ASIC) to process the input image data and display it. [0003] In a liquid crystal display (LCD), the output of its color image is composed of many pixels (pixels) on a color filter plate (color filter) and a transparent electrode plate, and the brightness of different colors is used to form an image by the pixels. . The pixels of a liquid crystal display are usually arranged in an ...
