Problems solved by technology

But unfortunately, the image processing data files can be easily extracted from the memory of the system controller, in other words, there is not enough way to protect these intangible assets of the manufacturer
In this way, speculators or individuals can obtain and use the information as they wish, which will bring considerable losses to the enterprises or inventors who create the image processing data files

Embodiment Construction

[0017] see figure 2 , figure 2 It is a functional block diagram of the image display system 200 according to the first embodiment of the present invention. Image display system 200 comprises: display device 236, is used for displaying image; Memory 216, is used for storing encoded data; The raw data is data processed to generate image pixel data to drive the display device 236 . Please note here that the development process device 201 is used to generate coded data according to the characteristics of the display device 236 , and the memory 216 is built in the memory controller 234 to store the coded data. After obtaining the display panel characteristic information, the display manufacturer encodes it and stores it in the memory 216 .

[0018] The aforementioned development process device 201 includes: a measuring device 202, which is used to measure the display device 236, to obtain the characteristics of the display device 236; a signal processing device 206, connected ...

Abstract

The present invention provides a method for displaying image pixel data including measuring display device characteristics from a display device, processing the display device characteristics, encoding the processed display device characteristics to generate encoded data, storing the encoded data in the memory, decoding the encoded data stored in a memory to generate decoded data, modifying pixel data according to the decoded data to generate the image pixel data and displaying the image pixel data on the display device.

Description

technical field [0001] The present invention provides an image display controller, in particular to an image display controller for protecting image processing information and related methods. Background technique [0002] Generally speaking, an image display system is roughly composed of some components, such as a system controller, a display device, a video input device, and a display controller, among which the display controller is a very important part of the overall image display system. [0003] One of the functions of the display controller is to use the image processing information stored in the image processing data file to convert the original image data into the image pixel data to be displayed. The conversion process must cooperate with the panel characteristics of the display device and other related information in order to for the best display; see here figure 1 , figure 1 It is a functional block diagram of a known image display system. The above functions...
