AI Technical Summary

Problems solved by technology

[0004] The problem with this system is that the picture sharpness enhancement function may enhance high-frequency signals in the picture, such as the edges of objects or picture noise particles, and the enhancement of high-frequency signals does not help the video encoder to encode more effectively. Reduce the encoding rate, because there is usually a large amount of data during monitoring, so the encoding efficiency will be greatly reduced

Abstract

The invention provides a method for enhancing acutance of a monitored picture, which comprises that: a monitoring camera shoots an image, processes the image, and performs video coding on the processed image to obtain video stream; and a monitoring center client receives the coded video stream from the monitoring camera, decodes the video stream, performs acutance enhancement on the decoded videostream, and displays the acutance enhanced image data.

Description

【Technical Field】 [0001] The present invention relates to the field of surveillance cameras, in particular to a method and device for enhancing the sharpness of surveillance images. 【Background technique】 [0002] With the further improvement of computer software and hardware processing capabilities and the rapid popularization of network applications, network-based video surveillance systems have become increasingly mature. The use of camera front ends with image acquisition functions and corresponding image display monitoring terminals can achieve video surveillance. In the surveillance applications in various places such as urban transportation, banks, hospitals, and major shopping malls, video surveillance systems have a strong use value. [0003] The structure of the existing video surveillance system can be found in figure 1 As shown, figure 1 It is a schematic diagram of the structure of the system 100 for enhancing the sharpness of the surveillance picture in the prior art....
