Problems solved by technology

[0002] In the field of image detection, it is often necessary to test the image quality displayed by the display terminal, and when the image data establishment time or hold time is not satisfied during the internal processing or transmission of image signals of the display terminal, noise will appear on the display terminal
Testers need to detect image abnormalities with the naked eye. On the one hand, staring at the screen for a long time will cause great damage to the human eye. On the other hand, the accuracy rate is low, and there may be missed tests, which will affect product quality.

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0018] An image abnormality detection device in one embodiment, such as figure 1 shown, including:

[0019] An acquisition module, configured to synchronously acquire image frames displayed by the detected display terminal, where the resolution of the acquisition module is greater than the display resolution of the display terminal;

[0020] The comparison module is used to compare the collected image frame with the preset reference frame, and judge whether there is any abnormality in the collected image frame according to the comparison result.

[0021] Such as figur...

Abstract

The invention discloses an image anomaly detection device and method. The device comprises an acquisition module and a comparison module; the acquisition module is used for synchronously acquiring image frames which a display terminal under detection displays; resolution of the acquisition module is greater than that of the display terminal; the comparison module is used for comparing the acquired image frames to a preset reference frame and judging whether or not anomalies occur to the acquired image frames according to comparison results. The image anomaly detection device and method has the advantages that quality of an image displayed on the display terminal is automatically tested so that detection labor is greatly relieved; testing results are more accurate, and chances that missing image anomalies occur in testing are slimmed; testing is simple, safe and reliable, and defects of a manual testing method are made up.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to an image abnormality detection device and method. Background technique [0002] In the field of image detection, it is often necessary to test the image quality displayed by the display terminal, and when the image data setup time or hold time is not satisfied during the internal processing or transmission of image signals in the display terminal, noise will appear on the display terminal. Testers have to detect image abnormalities with the naked eye. On the one hand, staring at the screen for a long time will cause great damage to the human eye. On the other hand, the accuracy rate is low, and there may be missed tests, which will affect product quality. Contents of the invention [0003] Based on the above situation, the present invention proposes an image anomaly detection device, which automatically tests the image quality displayed on the display terminal, greatly ...
