Abstract

The invention discloses a screen protection method and device, and belongs to the technical field of terminals. The method comprises the following steps: carrying out decoloring processing on an appointed image to obtain a grayscale image of the appointed image; in a switching process of a screen protection image, executing the following operation each time when the image is switched one time: according to the grayscale value of each pixel in the grayscale image, obtaining the corresponding color vector quantity of the grayscale value of each pixel in any colouring way from a color vector quantity mapping relationship; and according to the obtained color vector quantity, colouring the grayscale image, and displaying a coloured image. On the basis of the appointed image, the images which are coloured in different coloured ways are displayed each time in a screen protection process, a purpose that different display colors are replaced is realized, a screen protection purpose is realized, storage resources are saved, and the computation pressure of a processor is greatly lowered.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, in particular to a method and device for screen protection. Background technique [0002] Computers have become an important tool in people's life and work. People use computers for office, entertainment and processing various things almost most of the time. However, people do not always operate them. When the computer is idle for a long time, the computer usually switches automatically. to the screen saver mode, and can also be set by the user to switch to the screen saver mode. [0003] Among them, screen protection is a special technology designed to protect computer monitors. The principle of the screen protection technology is to dynamically display images in the standby state to prevent the screen from displaying the same image for a long time, thereby avoiding fatigue and aging of the light-emitting devices of the screen and prolonging the service life of the display. At prese...
