Image display method

Abstract

The invention is a video displaying method, applied to a computer system comprising a display, and comprising the steps of: reading a first frame from a first frame buffer; utilizing a 3D spatial video processing engine to make a video resolution processing on the first frame to form a second frame; writing the second frame into a second frame buffer; and according to a timing control data corresponding to the display, outputting the second frame to the display for displaying. And the method can use finite timing control data to support multiple display modes to reduce cost of product and improve use flexibility.

Description

technical field [0001] The present invention is an image display method, especially an image display method applied to a computer system including a display. Background technique [0002] Please refer to Fig. 1 a, which is a schematic functional block diagram of a graphics chip module part in a computer system, wherein the graphics chip module 11 can exist in an independent chip mode, or can be integrated in a north bridge chip (not shown), and the graphics chip The module 11 mainly reads out the pixel color value stored in the frame buffer (Frame Buffer) 10, and outputs it to an external display 12 for display. The number of pixels of the frame buffer (Frame Buffer) 10 set in the computer system is called resolution, for example, the common description of 1024×768 pixels or 1280×1024 pixels. Similarly, the number of pixels on a common display 12, such as a liquid crystal display, is referred to as the resolution of the display. [0003] But the resolutions of the internal...

Problems solved by technology

However, because the size of the viewing area of ​​the TV 14 varies slightly with the specifications of the manufacturer, the same timing control data cannot meet the needs of all TVs. Therefore, the designer of the graphics chip module 11 must correspond to TVs of various brands. To fine-tune different timing control data to meet the needs of TVs in different viewing areas

But this will greatly increase the size of the timing table, so the program code stored in the display interface basic input / output system 19 is too large, which increases the product cost and lacks flexibility in use. Therefore how to improve the deficiency of above-mentioned known means, just become the main purpose of the present invention
