Embodiment Construction

[0039] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0040] figure 1 It is a flow chart of the testing method of the video frame rate in an embodiment of the present invention, figure 2 It is a structural schematic diagram of an LED lamp array in an embodiment of the present invention; as Figure 1~2 As shown, a video array test method can be applied to the whole process of digital end-to-end equipment such as non-standard interface or non-standard transmission protocol or encryption technology (such as residential security technology prevention products, building intercom, etc.) Image signal test (such as the above-mentioned full image signal test can be realized by frame rate test (Frameratetest), and the digital end-to-end device can include a pattern generator composed of LED lamp arrays, and the method can include;

[0041] First, a video capture device for image capture is provided; the vid...

Abstract

The invention relates to the technical field of video test, and particularly relates to a video frame rate test method. The video frame rate test method can be used in whole process image signal test of a digital end-to-end device, and the digital end-to-end device comprises a graph generator provided with an LED lamp array; a plurality of LED lamps on the LED lamp array along a preset direction are selected to serve as a test lamp group, the test lamp group comprises a plurality of light emitting units, and each light emitting unit comprises a plurality of adjacent LED lamps; each light emitting unit is turned on in sequence, and the lighting frequency of the light emitting units is gradually increased; and an image displayed by the test lamp group is obtained by an image capturer in real time, and when the obtained image of the light emitting unit is static, the lighting frequency value on the graph generator at the moment is used as the value of the video frame rate of the digital end-to-end device, and then the whole process image signal test is completed. Since the video frame rate test method in the technical scheme is simple, easy to implement and is relatively high in test efficiency and reliability, the whole process image signal test can be completed quickly.

Description

technical field [0001] The invention relates to the technical field of video testing, in particular to a video frame rate testing method. Background technique [0002] At present, there are many digital end-to-end devices with no standard interface or non-standard transmission protocol or encryption technology. For example, the existing electrical signal-image signal test method cannot be used for effective testing, but all of them can only use end-to-end full process Image signal test. Among them, take the building intercom system, a residential security technology prevention product, as an example. Because of the non-standard transmission protocol and non-standard interface, the voice quality test can only be tested by the entire image signal. For example, in the home intercom, video has become an effective tool for information identification. The intercom loaded with video can not only allow the owner to hear the voice of the visitor clearly, but also effectively identif...
