Abstract
(EN)
A method and a device for video enhancement, and an electronic device are provided, in accordance with embodiments of the present disclosure. In the method, a current brightness of a display panel of the electronic device is obtained when a video is playing in the display panel. The current brightness may be compared with a target brightness, and a comparing result is obtained. An effect of video enhancement, which configured to be applied to the video, is determined according to the comparing result. The video is processed, by adjusting at least one parameters of images of the video, according to a video enhancement corresponding to the effect of video enhancement. Therefore, in the process of the video enhancement for the electronic device while playing video, the video may be displayed with extremely clear images and may have an extremely clear visual effect.

Selon certains modes de réalisation, la présente invention concerne un procédé et un dispositif d'amélioration de vidéo, ainsi qu'un dispositif électronique. Selon le procédé, une luminosité actuelle d'un panneau d'affichage du dispositif électronique est obtenue lors de la lecture d'une vidéo dans le panneau d'affichage. La luminosité actuelle peut être comparée à une luminosité cible, et un résultat de comparaison est obtenu. Un effet d'amélioration de vidéo, qui est conçu pour être appliqué à la vidéo, est déterminé en fonction du résultat de comparaison. La vidéo est traitée, par réglage d'au moins un paramètre d'images de la vidéo, selon une amélioration de vidéo correspondant à l'effet d'amélioration de vidéo. Par conséquent, dans le processus de l'amélioration de vidéo pour le dispositif électronique pendant la lecture de la vidéo, la vidéo peut être affichée avec des images extrêmement claires et peut avoir un effet visuel extrêmement clair.
