Terminal and terminal energy saving method

Abstract

The invention provides a terminal which comprises a detection unit, a request sending unit, a delay unit and an execution unit. The detection unit is used for detecting a current image after being drawn, namely detecting whether the current image is animation or not, if the current image is animation, detecting whether the animation is drawn well or not, and sending detection results; the request sending unit is used for receiving the detection results and sending a delay request when the detection results show that the current image is the animation which is drawn well; the delay unit is used for receiving the delay request and informing the execution unit after a preset delay time is up; and the execution unit is used for executing operations for drawing the next image of the animation after receiving the information of the delay unit. Correspondingly, the invention further provides a terminal energy saving method. By the technical scheme, the number of animation drawing is evidently reduced, so that operand of a CPU (central processing unit) and a GPU (graphic processing unit) can be lowered, power consumption can be lowered, and electricity saving is realized.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a terminal and a method for energy saving of a terminal. Background technique [0002] At present, the high power consumption of smart phones is an experiential problem that has always plagued users. Sometimes a battery will run out of power within a day, and users must go home to charge every day, which has become a laughing stock of smart phones. [0003] Among them, mobile phone animation can bring good visual effects to users, for example, when sliding the desktop, the icon follows the movement effect of the finger, the effect of fading in and fading out when the interface exits, etc., but drawing static images one by one on the screen, This process requires CPU and GPU to consume a lot of calculations, because as far as an ordinary two-dimensional image is concerned, it contains a lot of information, and each pixel in the image must contain information such as gra...

[0003] Among them, mobile phone animation can bring good visual effects to users, for example, when sliding the desktop, the icon follows the movement effect of the finger, the effect of fading in and fading out when the interface exits, etc., but drawing static images one by one on the screen, This process requires CPU and GPU to consume a lot of calculations, because as far as an ordinary two-dimensional image is concerned, it contains a lot of information, and each pixel in the image must contain information such as grayscale, color, channel, etc. , for example, for an ordinary 480*960 pixel picture, it contains 460,000 pixels, so as far as the image is concerned, it itself is a large data set; and no matter what kind of operating system, such as Android, Windows , Iphone, etc., from the bottom driver to the upper application, the whole process of realizing the drawing is quite complicated; in addition, the animation itself corresponds to a simple or complex mathematical model. It can be seen that to realize the animation, CPU, GPU (Graphic Processing Unit, Circular processor) involved in a huge amount of calculations, of course, this will consume a lot of power consumption
