Eye protecting method and device of screen based on virtual reality helmet

A method for eye protection based on a screen of a virtual reality headset, wherein the method comprises:

• calculating, based on a plurality of weight areas divided on the screen of the 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.

An apparatus for eye protection based on a screen of a virtual reality headset, wherein the apparatus comprises one or more modules configured to:

• calculate, based on a plurality of weight areas divided on the screen of the 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;
• determine, 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 obtain a suppressed blue component value of each pixel of an image at a next frame;
• output the image of the next frame imago with the suppressed blue component value.
