Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] refer to figure 1 , figure 1 It is a flowchart of an embodiment of the eye protection method based on the screen of a virtual reality helmet in the present invention, and the method includes:

[0032] Step S101: Based on multiple weight areas divided on the screen of the virtual reality helmet, calculate the blue component of the image pixel on the screen from t 0 to t 1 The total cumulative amount at all times, wherein the multiple weight zones are divided according to the weight of the impact of blue light on human eyes.

[0033] Due to the characteristics of the human eye, in the range of horizontal viewing angles, people have different perception capabilities in different angle ranges. As the angle increases, people's perception becomes weaker. For the image content on the screen, the closer to the center, the greater the impact on the ...

Abstract

The invention discloses an eye protecting method and device of a screen based on a virtual reality helmet. The eye protecting method includes: dividing the screen based on the virtual reality helmet into multiple weight areas, calculating the total cumulant of blue components of pixel points of an image on the screen from t0 to t1, wherein the weight areas are divided according to weights of influence of blue light on human eyes; according to the total cumulant of the blue components from t0 to t1, determining a blue light inhibitor at the time moment t1, then acquiring a blue component value of each pixel point of a next image frame after being inhibited; outputting a next image frame after the corresponding blue component value is inhibited. By the mode, a balance between human eye protecting and guaranteeing of display performance can be realized.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to an eye protection method and device based on a screen of a virtual reality helmet. Background technique [0002] The helmet-mounted display is the earliest virtual reality display, which uses the helmet-mounted display to close people's vision and hearing to the outside world, and guides the user to have a feeling of being in a virtual environment. The display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eyes will generate a three-dimensional feeling in the brain after obtaining this information with differences. As a virtual reality display device, the head-mounted display has the characteristics of small size and strong sealing, and has a wide range of applications in military training, virtual driving, virtual cities and other projects. [0003] Wearing a virtual reality helmet for a long time...
