White balance on-line automatic test system

Abstract

The embodiment of the invention discloses a white balance on-line automatic test system. The white balance on-line automatic test system comprises: a control host; a signal generator, which is connected with the control host, and is used for transmitting signals to the equipment to be tested, so that the equipment to be tested forms an image; a color analyzer, arranged in correspondence with the device under test, for analyzing the screen color of the device under test; a white balance correction module respectively connected with a color analyzer and a control host; a parameter adjustment execution module, which is connected with the white balance correction module, a device under test and the control host; and a photographing module, which is connected with the control host computer andthe equipment under test. The white balance on-line automatic test system of the invention adopts the mode of combining the white balance correction module and the parameter adjustment execution module, and then photographs and compares the screen images of the tested equipment through the photographing module, so that the visual effect of the product is consistent, the whole test system is fullyautomated, and the production efficiency is high.

Description

technical field [0001] The invention relates to a white balance test system, in particular to an online white balance automatic test system. Background technique [0002] Usually the color of the object will change due to the color of the projected light. If the white balance can be adjusted, the image can correctly use white as the base color to restore other colors. Whether the white balance is qualified or not has a great influence on the visual effect of the entire image. In factories that used to produce TVs or TV curtain walls, the same set of data was usually used to adjust the white balance of the machine. Later, it was found that the white balance of the products produced by this method could not be consistent, the color temperature difference was particularly large, and the visual effect was significantly different. , if the machines with differences are readjusted, the production efficiency is reduced. Contents of the invention [0003] The technical problem t...

Problems solved by technology

[0003] The technical problem to be solved by the embodiments of the present invention is that, for adjusting the white balance of the machine with the same set of data, the white balance of the produced products cannot be consistent, the color temperature difference is particularly large, and the visual effect difference is obvious, resulting in low production efficiency. A white balance online automatic test system is proposed
