The present disclosure provides a method and apparatus for extracting a video preview, a device and a computer storage medium. The method comprises: inputting a video into a video classification model obtained by pre-training; obtaining weights of respective video frames output by an attention module in the video classification model; extracting continuous N video frames whose total weight value satisfies a preset requirement, as the video preview of the target video, N being a preset positive integer. It is possible to, in the manner provided by the present disclosure, automatically extract continuous video frames from the video as the video preview, without requiring manual clipping, and with manpower costs being reduced.

Method and apparatus for extracting video preview, device and computer storage medium

A method of repairing a display panel comprising: determining a pixel where a bright spot defect resides and a position of the bright spot in the pixel; setting a repair region, the repair region being a region in the pixel including the bright spot defect and having an area smaller than that of a single pixel region; forming a black material layer in the repair region, the black material layer being used for preventing light emitted from a directly-below portion thereof from leaving a display surface of the display panel.

The present disclosure provides a video displaying method and apparatus, a device and a computer storage medium, wherein the method comprises: positioning a target video; displaying a video preview of the target video, the video preview being a video segment extracted from the target video. This displaying manner exhibits a stronger capability of expressing the video content. The user can better know whether the video is the desired content. The present disclosure may reduce a probability of the user missing desired video resources and reduce a probability that the user finds that the video content does not meet an expectation after he views the video content, thereby helping the user to conveniently and effectively view the desired video resources.

Video displaying method and apparatus, device and computer storage medium

An invisible laser system and an optical path visualization method thereof are disclosed. The invisible laser system comprises an invisible laser light generator for generating invisible laser light; a visible light generator for generating visible light; and an optical path visualization component arranged in optical paths of the invisible and visible light, and comprising a first and second incident end and a first outgoing end. The invisible laser light is incident on the first incident end, and the visible light is incident on the second incident end. All of the invisible laser light and at least part of the visible light are emitted in parallel with each other at the first outgoing end. All of the invisible laser light is present in a direction parallel with the optical path of the visible light, and no invisible laser light is present in other directions, so radiation risks are eliminated.
