Embodiment

[0050] Example: see attached Figure 1~4 Shown, an automatic test method for television images.

[0051] like figure 1 As shown, the automatic test method relates to a device for TV image testing; the device includes a transfer fixture 1, and the transfer fixture 1 includes at least three communication interfaces, wherein the first communication interface 2 is used for Connect the audio / video input and output interface 4 of the TV set 3 to be tested, the second communication interface 5 is used to connect the output interface 7 of an audio / video output device 6 (such as DVD), and the third communication interface 8 is used to connect an audio / video An input interface 10 of a video processing device 9 (such as a PC);

[0052]The audio / video output device 6 outputs audio / video to the TV 3 through the adapter fixture 1 . When switching between different TV sets 3 for testing, it is only necessary to disconnect the connection between the first communication interface 2 and the ...

Abstract

The invention relates to an automatic test method for a television image. Before starting, a comparison sample is prefabricated. The test method comprises the steps of: playing a video of the prefabricated sample by a to-be-tested television, and shooting imaging of the television by a camera; after totally completing shooting, sequentially comparing photos in actual imaging with photos in the sample one by one according to preset parameters; if matching out photos in the sample, obtaining a result that the thread passes the test, and adding a count with one; if not matching out the photos, carrying out matching in residual sample photos according to a preset time interval; if still not matching out the photos, determining that the thread does not pass the test; when the number of the passing threads is accumulated to a preset requirement, determining that the television passes the test; and when the number of the passing threads does not reach the preset requirement, continuously carrying out testing on a next thread, and unless the number of the tested threads reaches the total number of the threads, determining that the television does not pass the test. According to the invention, the full automatic test on imaging and playback functions of the television is implemented, efficiency is greatly improved, and reliability is ensured.

Description

technical field [0001] The invention relates to a test method, in particular to an automatic test method for television images. Background technique [0002] In the production process of television (TV) products, the pre-delivery test after the production is completed is a very important link. Before the TV product leaves the factory, it is necessary to test the image (imaging function) and sound (playback function) of the TV. [0003] The traditional test method is completely carried out manually. The tester needs to connect the TV to be tested first, then observe the imaging of the TV with his eyes, and listen to the sound of the TV with his ears at the same time, and draw a subjective judgment result. This traditional test method leads to extremely low test efficiency, and the reliability of the test cannot be guaranteed. [0004] Therefore, how to solve the above-mentioned deficiencies in the prior art becomes the subject to be studied and solved by the present invent...
