Embodiment Construction

[0029] like figure 2 As shown, the TV picture quality detection system of the present invention includes a sampling module 1 and a comparison module 2. The sampling module 1 is used to receive the picture frame of the picture to be tested, extract the sampling information in the picture frame, and send the sampling information. The comparison module 2 is configured to receive the sampling information, and compare the sampling information with the standard sampling information of the selected standard picture to obtain a picture quality comparison result. When the TV picture quality detection system is working, the standard picture is first sent to the sampling module 1, and the sampling module 1 extracts the sampling information of the standard picture as the standard sampling information, and sends the standard sampling information to the comparison module 2, and the comparison module 2 receives and The standard sampling information is stored as a benchmark for picture quali...

Abstract

The invention relates to a television picture quality detection system, which includes: a sampling module for sampling the picture frame information of the picture to be tested to obtain sampling information, and comparing the sampling information with standard sampling information of a selected standard picture to obtain A comparison module that displays picture quality comparison results. The sampling module extracts a plurality of line information and / or a plurality of field information in the picture frame as sampling information by identifying line and field synchronization information in the picture frame. The present invention also relates to a television picture quality detection method used in the above-mentioned system. By adopting the television picture quality detection system and method of the present invention, the automatic and fast detection of the television picture quality can be realized so as to accelerate the production speed and efficiency of the television.

Description

technical field [0001] The present invention relates to a TV picture detection technology, and more particularly, to a TV picture quality detection system and a method used by the TV picture quality detection system. Background technique [0002] With the popularization of large-screen and high-definition TVs, people's demand for TVs, especially large-screen TVs, is increasing. Therefore, the inspection of TV pictures is becoming more and more difficult. The original TV picture quality inspection needs Manual viewing, the inspection speed is slow and easy to cause misjudgment, and the quality of inspection cannot be guaranteed. With the large-scale production of large-screen TV motherboards, an automatic and fast TV picture quality detection method is urgently needed to speed up the production speed and efficiency of TVs. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is that, in view of the defects of the prior art that the ...
