Method and system for optimizing video playback power consumption

Abstract

The invention relates to the field of optimization processing, and particularly relates to an optimization method and system for power consumption of video playing. The optimization method comprises the steps of acquiring a first resolution of a frame image in a video to be played and a display resolution of a display terminal; if the first resolution is less than the display resolution of the display terminal, increasing the pixel value of each pixel of the video to be played by a preset threshold, and expanding the first resolution of the video to be played by adopting a mode of filling black pixels in a staggered row and staggered column mode. According to the invention, the first resolution of the video to be played is expanded by adopting the mode of filling black pixels in a staggered row and staggered column mode to replace a different algorithm mode in the prior art, so that the power consumption of a low-resolution video played on high-resolution equipment is reduced. In addition, brightening is realized through increasing the pixel value of each pixel of the video to be played by the preset threshold, so that the loss in image quality brought about by the black pixels is compensated, and the power consumption of video playing is reduced under the condition of ensuring the image quality to approach to the original image quality.

Description

technical field [0001] The invention relates to the field of optimization processing, in particular to a method and system for optimizing power consumption of video playback. Background technique [0002] With the development of mobile communications and the continuous improvement of people's living standards, the use of mobile phones, especially smart phones, is becoming more and more popular. Users can use their smartphones to watch videos online. At present, many low-resolution videos are played on smartphones. Since the display resolution of smartphones is different from the resolution of videos, it is necessary to expand the pixels through the difference algorithm to increase the resolution of the original video to the same level as that of smartphones. However, using the above method to solve the problem will cause the smart phone to consume more power. At present, there is no better way to solve the problem of optimizing the power consumption of video playback. Con...
