Embodiment Construction

[0029] Such as 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 this television picture quality detection system works, at first standard picture is sent to sampling module 1, extracts the sampling information of standard picture by sampling module 1 as standard sampling information, and standard sampling information is sent to comparison module 2, comparison module 2 receives and The standard sampling information is stored as a benchmark for picture quality comparison. If there a...

Abstract

The invention relates to a television picture quality detection system, which comprises a sampling module for sampling information of a picture frame of a picture to be tested to acquire sampling information, and a comparison module for comparing the sampling information with standard sampling information of a selected standard picture to acquire a picture quality comparison result, wherein a plurality of line information and / or field information are extracted from the picture frame as the sampling information by the sampling module through identifying line-field synchronization information in the picture frame. The invention additionally relates to a television picture quality detection method used by the television picture quality detection system. By adopting the television picture quality detection system and the method thereof, which are disclosed by the invention, the television picture quality can be detected automatically and rapidly, and thereby the production speed and the efficiency of a television are increased.

Description

technical field [0001] The invention relates to a TV picture detection technology, more specifically, to a TV picture quality testing system and a method used in the TV picture quality testing system. Background technique [0002] With the popularity of large-screen and high-definition TVs, people's demand for TVs, especially large-screen TVs, is increasing, so 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 it is easy to cause misjudgment, and the quality of the inspection cannot be guaranteed. Along with large-scale production of large-screen TV motherboards, there is an urgent need for an automatic and quick TV picture quality detection method to speed up the production speed and efficiency of TVs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic, fast and less misjudged TV picture ...
