To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of method for weakening display picture smear, as shown in Figure 1, comprising:
Step 101, it according to the attribute information of the display screen of virtual reality device, determines to the black pixel mould of the rendering of image
Formula；It include that the first rendering is regular and the second rendering rule, first rendering are regular and described in the black voxel model of rendering
Need the position of rendered pixel not exactly the same described image in second rendering rule；
Step 102, obtaining needs n-th frame image to be loaded, according to the first rendering rule to the n-th frame image into
Row renders black processes pixel；
Step 103, obtaining needs the (n+1)th frame image to be loaded, according to the second rendering rule to the (n+1)th frame figure
As carrying out rendering black processes pixel.
In a step 101, image is carried out rendering black pixel being exactly to utilize CPU (central processing unit), GPU (graphics process
Device) either other hardware black picture element is become to the partial pixel needed on image to be loaded or whole pixels.
In embodiments of the present invention, the attribute information of the display screen of the virtual reality device includes following any or group
It closes: refresh rate, resolution ratio and brightness.Being determined according to one kind of above-mentioned attribute information or combination needs image to be loaded
Black voxel model is rendered, optionally, in embodiments of the present invention, the display screen refresh rate of virtual reality device is higher, resolution ratio
Higher and brightness of display screen is higher, and in the black voxel model of determining rendering, the number of pixels rendered in image is got over
More, that is, ratio of the pixel for needing to render in all image pixels is bigger.That is, different virtual reality devices are due to tool
There is the display screen of different size, so what is determined is also different to the black voxel model of image rendering.
In a step 101, the black voxel model of the rendering to image determined may include two kinds of rules, i.e., virtual using this
The display screen of real world devices currently needs image to be shown using the first rendering rule in user, and user needs after moveable head
Image to be loaded is rendered using the second rendering rule, in embodiments of the present invention, the first rendering rule and described second
Need the position of rendered pixel can be entirely different described image in rendering rule, such as the picture element matrix that image is 2 × 2,
First rendering rule is the pixel of the first row in rendering image, and second renders rule as the picture of the secondary series in rendering image
Element, then the position of the pixel in the image of the first rendering rule rendering renders the pixel in the image of rule rendering with second
It is entirely different.
Certainly, in embodiments of the present invention, described image is needed to render in the first rendering rule and the second rendering rule
The position of pixel can also be not exactly the same, i.e., when the first rendering rule and the second rendering rule render image, there is phase
Pixel with position is rendered by the first rendering rule, is also rendered by the second rendering rule, such as the pixel that image is 2 × 2
Matrix, the first rendering rule are the pixel of the first row the first row in rendering image, and the second rendering rule is in rendering image
The pixel of the first row secondary series, the then position of the pixel in the image of the first rendering rule rendering and the second rendering rule rendering
Image in pixel it is not exactly the same.
In a step 102, n-th frame image refers to user when using virtual reality device, needs to load virtually existing
Picture in the display screen of real equipment, n are greater than zero.(n+1)th frame image refers to that user is using virtual reality device movable head
When portion, need to load the picture in the display screen of virtual reality device.
In embodiments of the present invention, there is picture smear in the display screen prospect of virtual reality device and the boundary part of background
Problem is as shown in Figure 2 and Figure 3, and Fig. 2 is that virtual reality device needs n-th frame figure to be loaded, i.e. user needs in virtual reality device
Display in the picture material watched, and when Fig. 3 is user movement head, virtual reality device needs the (n+1)th frame to be loaded
Image, i.e. user need the picture material watched in the display of virtual reality device.
In Fig. 2 and in Fig. 3,201 indicate bright colored portion in n-th frame image, and 202 indicate the dead color in n-th frame image
Part, in order to better illustrate picture smear problem, in Fig. 2,201 indicate foreground part in n-th frame image, and 202 indicate
Background parts in n-th frame image, indicate the boundary of foreground part and background parts with 1 and 2,1 indicate be foreground part with
Boundary of the background parts in foreground part, boundary of 2 foreground parts and background parts indicated in background parts.
When user's head turns left, image to be loaded is needed to become the (n+1)th frame in Fig. 3, labeled as 1 pixel
Brightness is dark by bright turn, and labeled as 2 pixel, the brightness of pixel is by blackout amount, due to the response of the display screen of virtual reality device
Time is longer, i.e., display response pixel brightness by blackout it is bright or by bright turn of dark time it is long, along with human eye
Visual persistence phenomenon, so user is the phenomenon that being observed using virtual reality device, the pixel that the label labeled as 1 is
Region, pixel intensity are the mixed number of 1 pixel and 2 pixels, and here it is the trailing phenomenon of common display.
In order to effectively weaken the trailing phenomenon of display, in embodiments of the present invention, obtaining needs n-th frame figure to be loaded
Picture carries out rendering black processes pixel according to the first rendering rule to the n-th frame image；Obtaining needs to be loaded (n+1)th
Frame image carries out rendering black processes pixel according to the second rendering rule to the (n+1)th frame image.
In embodiments of the present invention, there is using human eye to black color the visual effect of pause picture, utilize two kinds of wash with watercolours
Dye rule respectively renders the pixel in two images, so that being located at foreground part and background in the two images after rendering
Edge pixel brightness between part can be bright by blacking, bright by blacking, since display is to by secretly brightening than by bright change case
The response time of pixel variation is short, so can effectively weaken the problem of hangover.
