Abstract: Provided is a terminal, comprising: an acquisition unit which acquires the moving speed of the terminal; a determination unit which is used for determining whether a user of the terminal gazes upon a screen of the terminal when the moving speed is greater than or equal to a first moving speed and is less than or equal to a second moving speed; and a processing unit which performs a corresponding security processing operation when the determination result of the determination unit is yes. Correspondingly, also provided is a terminal management method. Corresponding reminding and limitation can be performed when a user plays with a mobile phone while walking so as to guarantee the personal security of the user.

Abstract: The present application provides a an image compensation method for side-emitting backlight comprising steps of: S1, dividing the display screen into several regions; S2, arranging virtual light sources at one side of each region where actual light sources are located for imitating the actual light sources; S3, inputting a pixel value and a coordinate of the point to be compensated; S4, computing a ratio value between an all-full-lighting backlight brightness of the point to be compensated when fully lighted and an all-reduced backlight brightness of the point to be compensated when reduced in brightness; S5, obtaining a compensation factor of the point to be compensated, according to the ratio value; S6, compensating the pixel value of the point to be compensated by using the compensation factor; S7, determining whether all the points to be compensated in the image to be compensated have been compensated or not.
