Image processing device and image processing method for game loop
An image processing method for a game loop of a game, wherein the game loop comprises a game rendering module and a MEMC module, and is executed by more than one processing unit to generate an output image to display. The image processing method includes rendering, by the game rendering module, a scene of the game to obtain a first image; rendering, by the game rendering module, a UI to obtain a second image; applying, by the MEMC module, MEMC to the first image to generate an interpolated first image; and blending, by the MEMC module, the second image and the interpolated first image into the output image.
1. An image processing method for a game loop of a game, wherein the game loop comprises a game rendering module and a motion estimation and motion compensation (MEMC) module, and a program of the game loop is stored in a non-transitory computer-readable medium and executed by more than one processing unit to generate an output image to display, the image processing method comprising:
rendering, by the game rendering module, a scene of the game to obtain a first image;
rendering, by the game rendering module, a user interface (UI) to obtain a second image;
applying, by the MEMC module, MEMC to the first image to generate an interpolated first image; and
blending, by the MEMC module, the second image and the interpolated first image into the output image to display.
2. The image processing method of claim 1 , wherein one of the more than one processing unit is a graphics processing unit (GPU).
3. The image processing method of claim 1 , wherein the first image is obtained by 2D or 3D rendering of the scene of the game.
4. The image processing method of claim 1 , wherein the second image is an image with opacity.
5. The image processing method of claim 1 , wherein the step of applying the MEMC to the first image to generate the interpolated first image comprises:
performing, by the MEMC module, motion compensation to generate the interpolated first image according to a motion data and the first image.
6. The image processing method of claim 5 , wherein the step of obtaining the motion data comprises performing motion estimation to obtain the motion data.
7. The image processing method of claim 5 , wherein the game rendering module or the MEMC module provide the motion data.
8. The image processing method of claim 5 , wherein the motion data comprises a plurality of motion vectors of the first image.
9. The image processing method of claim 1 , wherein the step of blending the second image and the interpolated first image into the output image comprises performing an alpha blending to blend the second image and the interpolated first image.
