Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] figure 1 A flow chart of an embodiment of a method for improving video definition provided by the present invention is shown. Such as figure 1 As shown, the present invention provides a method for improving video clarity, which method includes: performing edge extraction on the original image frame in the video (step S10); and superimposing the image frame obtained by edge extraction on the The original image frame is obtained to obtain a new image frame, and the new image frame constitutes the video (step S20). The method can improve the definition of the video by improving the definition of the edge in each frame image, instead of changing the resolu...

Abstract

The invention relates to the field of video processing, and discloses a video resolution improving method and device. The method comprises the steps that edge extraction is carried out on an original image frame in a video; an image edge acquired through edge extraction is superimposed to the original image frame to acquire a new image frame; and the new image frame forms the video. According to the video resolution improving method and device, for a standard definition video, the resolution is obviously improved; and a viewer can view the video of better resolution by spending less traffic.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a method and device for improving video clarity. Background technique [0002] At present, the video resolution in the video industry is standardized as SD, HD, and UHD, among which SD is a video format with a physical resolution below 720p. As we all know, when watching or downloading videos, high-definition and ultra-high-definition videos require more traffic than standard-definition videos, but the definition of standard-definition videos is worse than that of high-definition and ultra-high-definition videos. I hope to see videos that cost less traffic and have clearer quality. [0003] In the prior art, to improve the video definition is mainly solved by increasing the resolution of the video. For a video, this undoubtedly increases the traffic consumption. Contents of the invention [0004] The object of the present invention is to provide a method and device for...
