[0070] See figure 2 , Is proposed as an embodiment of the rendering control method of the present invention, and the method includes:

[0071] S201: When the mobile terminal starts the virtual reality application, the refresh rate value of the front camera of the mobile terminal is increased from the default refresh rate value to the preset target refresh rate value.

[0072] The specific value of the target refresh rate value in this embodiment can be specifically selected according to the user's eye movement speed. In theory, when it can completely adapt to the user's eye movement speed, a rendering area that completely covers the rotation speed of the human eye can be calculated. As far as possible, avoid the user from perceiving the rough rendering image outside the fine rendering area during rapid eye movement, and improve the user's visual experience and satisfaction.

[0073] S202: Calculate the fine rendering area according to the obtained target refresh rate value and the c...

[0092] On the basis of the first embodiment, the embodiment takes the target refresh rate value to take the maximum refresh rate value of the camera, V is 500° / sec, θ1 is 15°, FPSs is 60FPS, and t is 0.01 seconds as an example. A mobile terminal with a camera's FPSc of 30FPS is described as an example. For the rendering control process at this time, see Figure 5 Shown, including:

[0093] S501: When the mobile terminal starts the virtual reality application, the refresh rate value of the front camera of the mobile terminal is increased from the default refresh rate value to the maximum refresh rate value of the camera.

[0094] S502: Calculate the fine rendering area according to the obtained maximum refresh rate value and the current gaze point of the user on the screen of the mobile terminal.

[0095] The calculation process of this part is as follows:

[0096] First calculate the fine rendering range θ according to the following formula (1):

[0114] See Figure 5 , Is proposed as a schematic structural diagram of the rendering control device of the present invention. The rendering control device in this embodiment can be set in a mobile terminal, and the mobile terminal stores a list of mainstream VR applications on the market before leaving the factory, and provides a setting menu for the user to add and delete VRs in the list. application. The user opens the application in the VR application list, the system switches the working mode to the VR working state, turns on the front camera to capture the user's eye image, and the rendering control device adjusts the refresh rate value of the camera according to the corresponding graph, and completes based on this The corresponding rendering control. Rendering control device structure see Figure 5 As shown, the rendering control device includes: a camera control module 52, a rendering area calculation module 53, a rendering module 54 and a display module 55;

Abstract

The invention discloses a rendering control method, a rendering control device and a mobile terminal. The method comprises the following steps of promoting a refresh rate value of a front camera to a preset target refresh rate value from a default refresh rate value when the mobile terminal opens a virtual reliability application; figuring out a fine rendering region according to the target refresh rate value obtained after promotion and the current point of regard of a user on a screen of the mobile terminal in order to carry out fine rendering on pixel points in the fine rendering region; carrying out normal rendering processing on other regions outside the fine rendering region; and lastly, presenting a rendered picture to the user on the screen. The invention has the following beneficial effects that the precise rendering region is determined by the target refresh rate value which can be better adaptive to the rapid eye movement than the existing fixed refresh rate value, the obtained precise rendering region can better cover the visual range of the user, the user is prevented from perceiving a rough rendering picture outside the fine rendering region during the rapid eye movement, and the visual perception and the satisfaction of the user are improved.

Description

Technical field [0001] The present invention relates to the field of virtual reality technology, in particular to a rendering control method, device and mobile terminal. Background technique [0002] Virtual reality technology (Virtual Reality, VR) is a simulation system that can create and experience virtual worlds. It generates a simulation environment that is a system simulation of interactive three-dimensional dynamic visual scene and entity behavior with multi-source information fusion. Immerse the user in the environment. With the increasing maturity of VR technology, its application fields are also increasing, such as games and multimedia fields. At present, mobile terminals such as mobile phones are communication and entertainment equipment that people carry with them and are indispensable in current life. Therefore, various VR head-mounted devices (HMD, HeadMounted Device) have been developed for mobile terminals in the market. After the VR head-mounted device slots or...
