Embodiment 1

[0049] refer to figure 1 , showing a flow chart of a VR screen display method, the method may specifically include the following steps:

[0050] Step 101: Obtain brightness perception values ​​corresponding to each target moment in each visual stage of the human eye.

[0051] In the case of sudden changes in ambient light intensity, due to the action of physiological mechanisms, the human eye cannot immediately perceive and adapt to changes in the brightness of the environment, but has a time-delayed adaptation process. When we enter a bright environment from a dark environment, we initially feel glare in front of our eyes and cannot see objects clearly, but we can recover our vision after a while. This process is called light adaptation. For example, for a VR device that plays VR video, the display method is to directly light up the screen according to a preset brightness value after the user wears the VR device. This process is equivalent to the human eye suddenly switching...

Embodiment 2

[0065] refer to figure 2 , showing a flow chart of another VR screen display method, the method may specifically include the following steps:

[0066] Step 201: Obtain brightness perception values ​​corresponding to each target moment in each visual stage of the human eye.

[0067] In the embodiment of the present invention, since the subjective brightness perceived by the human eye, that is, the relationship between the brightness perception and the objective brightness of the actual environment follows the Weber-Fechner law, it can be obtained based on actual tests or simulations. Each luminance perception value in different visual stages is fitted to obtain the luminance perception response curve of the human eye in the scotopic stage, the luminance perception response curve of the human eye in the intermediate vision stage, and the luminance perception response curve of the human eye in the photopic vision stage.

[0068] image 3 The luminance perception response curve...

Embodiment 3

[0113] refer to Figure 6 , shows a block diagram of a VR display device 600, the device may specifically include:

[0114] An acquisition module 601, configured to acquire brightness perception values ​​corresponding to each target moment in each visual stage of the human eye;

[0115] An establishment module 602, configured to establish a screen brightness relational expression of the VR screen according to the perceived brightness value and the light transmittance of the lens disposed on the light-emitting side of the VR screen;

[0116] A display module 603, configured to display according to the screen brightness relational expression.

[0117] Optionally, the vision stage includes a scotopic stage, an intermediate vision stage and a photopic stage; the building module 602 includes:

[0118] The first establishment sub-module 6021 is used to establish the VR screen corresponding to the first screen of the scotopic stage according to the brightness perception values ​​of...

Abstract

The embodiment of the invention provides a VR screen display method and a VR display device, and relates to the technical field of VR. The method includes the steps: acquiring a brightness sense valuecorresponding to each target moment at each visual stage of the human eyes; establishing a screen brightness relation of a VR screen according to the brightness sense value and a light transmittanceof a lens disposed on a light exiting side of the VR screen; performing the displaying according to the screen brightness relation. In the embodiment of the present invention, the VR device can perform adaptive brightness adjustment according to the brightness adaptability of the human eyes at different visual stages when the screen is bright, so that the VR screen is slowly lighted, thereby preventing the VR screen from directly lighting to cause glare and puffy, and reducing the damages of the VR screen light to the human eyes.

Description

technical field [0001] The present invention relates to the technical field of VR, in particular to a VR screen display method and a VR display device. Background technique [0002] With the rapid development of simulation technology, people pay more and more attention to virtual reality (English: Virtual Reality, VR for short) technology. VR technology enables users to watch a virtual scene similar to a real three-dimensional scene by performing three-dimensional processing on the video captured by the omnidirectional camera device. It can be widely used in education and training, fire drills, virtual driving, architectural display and many other fields. [0003] Usually, people can watch VR videos through head-mounted VR devices such as VR helmets. In order to obtain a good sense of immersion, the shape of the current head-mounted VR devices is designed according to ergonomics, sealing the facial space, so that users can basically see when wearing them. Without external a...
