System and method for automatic white balance adjustment

Abstract

The invention discloses a system and a method for automatic white balance adjustment. The hardware system of the system comprises a PC host computer, a controllable signal source, a colorimeter electrically connected with the PC and a debugging tool electrically connected with the PC and a television to be tested, wherein the PC host computer is used for controlling the operation of the whole system; the controllable signal source is used for providing a test signal; the colorimeter is used for measuring white balance data and transmitting the data back to the PC for processing; and the debugging tool is used for shielding the difference caused by the use of different main chips of the television to a PC control end. The method comprises: 1) performing overall data test of a model machineand computing debugging reference data; 2) debugging at least one group of white balance mode for online debugging; 3) computing other white balance data according to the debugging reference data; and 4) writing the other white balance data in the television to be debugged. In the system and the method, the all-mode computing can be completed through one or a few white balance mode, so the overall debugging and the overall automatic analysis and debugging are completed at high debugging speed.

Description

technical field [0001] The invention relates to flat digital TV technology, in particular to an automatic white balance debugging system and method for flat digital TV. Background technique [0002] Currently mainstream LCD, plasma and other flat-panel TV products can receive many signal channels, including RF radio frequency, AV, S-Video, YpbPr, VGA and HDMI. There are differences in the processing flow when processing different channel signals, but the processing software uses the same white balance parameters during processing, which often shows inconsistent white balance on different channels. [0003] In order to solve this problem and make the white color processed by different signal channels show the same effect, the prior art generally adopts different white balance parameters for different signal channels and even signal formats to compensate for differences in hardware and signal flow. The difference in white balance caused by the difference. The design of this ...

Problems solved by technology

However, due to the increase of white balance parameter groups, it brings great difficulties to the white balance debugging in the production process, because the production process requires a faster debugging speed, and after the white balance is set for different signals, if the full debugging method whose speed will be unbearably
