Video image enhancement processing method and processing system, and player end

Abstract

The invention discloses a video image enhancement processing method and processing system, and a player end. The video image enhancement processing method comprises steps of A. decoding to obtain original playback data; B. enhancing and rendering a video image so as to obtain terminal playback data, wherein the enhancement and rendering process of the video image comprises the step of performing image enhancement on original playback data according to strength parameter value Ecur; C. playing data by the display terminal; following steps are included between A and B: D. setting a theoretical maximum and minimum of a strength parameter value, setting a subjective effective maximum and minimum of the strength parameter value; E. acquiring a current brightness value Lcur of a playback screenin real time; F. determining a strength parameter value Ecur according to Lcur; and G. checking validity of the strength parameter value Ecur and updating the strength parameter value Ecur. Strength for image enhancement is regulated adaptively in real time according to brightness of the playback screen, user interaction operation is omitted, watching effect is better and user experience is higher.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a video image enhancement processing method, a processing system, and a player terminal. Background technique [0002] In order to improve the quality of video images and enhance viewing experience, image enhancement processing is usually performed on video images. Image enhancement processing includes operations such as contrast expansion, color enhancement, filtering, detail enhancement, and edge enhancement. [0003] In addition to being affected by video image quality, user viewing experience is also directly affected by the brightness of the playback screen on the player side. On mobile devices, the screen brightness of the playback screen will be adaptively adjusted according to the light intensity of the environment. Normally, when the brightness of the playback screen is bright, viewers have greater tolerance for contrast, details, and sharpness; wh...

AI Technical Summary

Problems solved by technology

[0005] For the server side, since the video image enhancement process can only affect the video image itself, it cannot consider the viewing environment of the viewer, so it is naturally impossible to achieve the best image enhancement viewing experience

[0006] For the player side, although the video image enhancement processing directly on the player side can consider and affect the viewing experience of the viewer, however, the existing video image enhancement processing methods all preset several levels according to the multi-level adjustment requirements. The video image enhancement intensity parameter value depends on the user to manually select and adjust the gear, and the screen brightness of the playback screen is adjusted in real time according to the ambient brightness, so the multi-level fixed enhancement processing method cannot achieve the best viewing experience

At the same time, due to the need for users to manually adjust the intensity of video image enhancement, the user experience is poor

[0007] To sum up, the existing video image enhancement processing methods do not consider the brightness factor of the playback screen on the player side, so the enhancement intensity is usually too large or insufficient, and the optimal user viewing experience cannot be achieved.
