Embodiment

[0024] The automatic white balance debugging method at the smart TV end of the embodiment of the present invention includes a white balance parameter acquisition part and a white balance parameter use part.

[0025] Wherein, the white balance parameter acquisition part includes the following steps:

[0026] Step 1. Connect the smart TV to the color temperature meter, connect its HDMI port to the signal generator, connect its UART serial port to the computer, and connect the computer to the color temperature meter.

[0027] Here, it is preferable to uniformly adopt the same color temperature meter and signal generator, and the signals sent by the signal generator are also unified, so as to ensure the universality of computer software and smart TV software on all platforms. In this example, the color temperature meter is The model is CA-310 color temperature meter, the signal generator outputs HDMI signal, the format of the HDMI signal is full white signal of 1080i 60Hz and 80% ...

Abstract

The invention relates to the smart TV technology. The invention is to solve the problem that the consistency of a subjective effect cannot be satisfied by use of fixed white balance parameters since the color temperature status consistency of a liquid crystal screen in the existing smart TV. The invention provides an automatic white balance debugging method at a smart TV side. The technical scheme can be generalized as follows: the automatic white balance debugging method at the smart TV side comprises the white balance parameter acquisition part and the white balance parameter usage part. The method disclosed by the invention has the advantages that the debugging efficiency is improved, the production cost is lowered, and the method is suitable for the white balance parameter debugging of the smart TV.

Description

technical field [0001] The invention relates to smart TV technology, in particular to the technology of smart TV white balance debugging. Background technique [0002] Whether the white balance parameters are qualified or not has a great influence on the subjective effect of the image. In the past, the white balance of LCD TVs was debugged through a single prototype. After obtaining the data, it was written into the program. A set of data, however, due to the poor consistency of the color temperature state of the LCD screen itself, the use of fixed white balance parameters cannot meet the consistency of subjective effects. In addition, the manual adjustment of white balance parameters in the production line is slow, inefficient, and the accuracy rate is not high. Secondly, different chip development white balance adjustment software algorithms are also different, resulting in waste of software development resources. Contents of the invention [0003] The purpose of the pr...
