In the present invention is implemented, user equipment (User Equipment, referred to as " UE "), also referred to as terminal (Terminal).The terminal carries out image procossing to the display image exported frame by frame, is superimposed shielding patterns on the display image of every frame.Shielding patterns in successive frame change in a certain order, and terminal exports the display image after superposition shielding patterns frame by frame.According to the frequency of terminal output image, certain in a flash, display image can not completely be shown, but vision is combined to stop principle, and user can see complete display image.In embodiments of the present invention, terminal can be mobile phone, the equipment that tablet computer, TV etc. have display.
For purposes of illustration only, being described in detail below with reference to technical solution of the Fig. 1 to the embodiment of the present invention.It should be understood that this is only an example to illustrate the technical solution of the embodiment of the present invention, any restriction is not constituted to the embodiment of the present invention.
Fig. 1 is the schematic flow diagram of image processing method of the embodiment of the present invention.The executing subject of image processing method 100 as shown in Figure 1 is terminal, and this method 100 includes:
110, display image is received frame by frame；
120, determine that every frame shows that the shielding patterns of image, shielding patterns block a part of display image；
130, image is exported frame by frame, and output image is the superposition for showing image shielding patterns corresponding with the display image.
Terminal receives display image by preset frame rate frame by frame.Terminal exports image by preset frame rate frame by frame, each output image is continuously exported with N frame.The display image in output image that N frame continuously exports is identical.Every frame shows that each pixel of image at least goes out in the output image that N frame continuously exports
The pattern that is not blocked once now blocks.In the output image that N frame continuously exports, the display image of every non-shield portions of frame shielding patterns meets vision and stops principle.N takes positive integer.
Specifically, in embodiments of the present invention, terminal exports image according to preset frame rate.Terminal, which shows every frame, shows the corresponding shielding patterns of image described in image superposition.The shielding patterns superposition corresponding with display image of display image synthesizes output image.Every frame shows that the corresponding shielding patterns of image only block the partial pixel that the frame shows image.Every frame shows that each pixel of image pattern that is not blocked at least once in the output image that N frame continuously exports blocks.When preset frame rate meets user's vision residence time, when continuous N frame output image, stopping principle in conjunction with vision, vision is detained principle in other words, and user can be when seeing that next frame exports image, previous frame output image is also retained in the sight of user, and user can see complete display image.
Wherein, the shielding patterns of different frame can be different, and can change in a certain order.
In 110, the display image that display image can need to export for terminal.Terminal receives the display image for needing to export frame by frame.
In 120, shielding patterns can be used for blocking the partial information of display image.Terminal shows that image determines a shielding patterns to every frame.
In embodiments of the present invention, the shielding patterns of every frame can block the partial pixel that corresponding frame shows image.The shielding patterns of successive frame can be different, and can change in a certain order.According to the frame number of terminal one second output image, determine that each pixel of display image exports the pattern that is not blocked at least once in image in successive frame and blocks.In order to meet user demand, the display image that pattern blocks that is not blocked in every frame meets vision and stops principle, can see complete display image to meet user.
Wherein, in embodiments of the present invention, N is the frame number of terminal output output image per second,.
In 130, terminal exports image frame by frame, and output image is the superposition for showing image shielding patterns corresponding with image is shown.
