Abstract: The present invention discloses a method and an apparatus for eye protection based on a screen of a virtual reality headset, the method comprising: calculating, based on a plurality of weight areas divided on a screen of a virtual reality headset, a total cumulative amount of a blue component of pixels on the screen from a t0 moment to a t1 moment, wherein the plurality of weight areas is divided according to weights of impact of blue light on human eyes; determining, according to the total cumulative amount of the blue component from the t0 moment to the t1 moment, a blue light suppression factor at the t1 moment, and then obtaining a suppressed blue component value of each pixel of an image at a next frame; outputting the image of the next frame with the suppressed blue component value. In such a way, the present invention can strike a balance between eye protection and guarantee of display performance.

Abstract: The present invention discloses a color display method and system for a mobile terminal. According to the method, an environmental ambient light level for a mobile terminal is detected, a color enhancement factor is calculated according to the ambient light level, and display color of the mobile terminal is enhanced according to the color enhancement factor. A color enhancement technology widely used in a display screen is combined with the environmental ambient light level. The color enhancement is dynamically adjusted according to the intensity of ambient light.
