Problems solved by technology

[0004] Another motion compensation frame insertion device and frame insertion method is a motion estimation compensation device and method based on motion segmentation. Although this frame insertion device and method can solve the problem of "flicker", it will make the inserted frame unable to point by point. Complete, and although this device and method can effectively improve the interpolation effect of moving objects, because the motion vector of the pixels in the occlusion / revealing area cannot be obtained, the frame interpolation effect of the occlusion / revealing area cannot be improved, that is, the occlusion cannot be well area for estimation and processing, so the effect of inserting frames is still not ideal
[0005] Moreover, neither the existing motion compensation frame interpolation device nor frame interpolation method can achieve frame interpolation at any time point

Embodiment Construction

[0042] Such as figure 1 As shown, it is a schematic diagram of the interpolation of the occlusion area and the exposure area of ​​the present invention. The so-called occlusion area is the background area that exists at the previous moment and is blocked by the moving object at the next moment, and the exposed area is the background area that is covered by the moving object at the previous moment and revealed due to the movement of the object at the next moment. Such as figure 1 As shown, areas A, B, and C are background areas of moving objects. From time T-3 to time T-1, due to the movement of moving object D, background area B is blocked by D, so B becomes an occlusion area, and from From time T-1 to time T+1, due to the movement of the moving object D, the background area A is blocked by D, so A becomes the occluded area, and the originally occluded background area C is revealed, and C becomes the exposed area. From time T+1 to time T+3, due to the movement of D, area B i...

Abstract

We describe a motion compensated frame interpolation apparatus and method that includes a motion vector interpolation module for an object and uncovered area to generate information for motion vectors that cross interpolated pixels in object and / or uncovered areas. A motion vector interpolation module for a covered area generates information for motion vectors that cross interpolated pixels in covered areas. A motion vector counter records a number of motion vectors that cross an interpolated pixel. A buffer for motion vector interpolation buffers the information for motion vectors that cross interpolated pixels in the object and / or uncovered areas and the covered areas. And a video data interpolation module generates video data of the interpolated pixels in object and / or uncovered areas and the covered areas.

Description

technical field [0001] The invention relates to a motion compensation frame insertion device and frame insertion method, in particular to a motion compensation frame insertion device and frame insertion method that can be used to solve occlusion problems. Background technique [0002] The quality of images displayed by a display device largely depends on the scanning mode and image refresh rate. The scanning mode of traditional display devices is interlaced scanning, and its image refresh rate is generally 60 fields / second. [0003] In order to improve the quality of the image, most of the existing methods use progressive scanning and increase the refresh rate. The method of increasing the refresh rate is to insert frames. The frame insertion device and frame insertion method usually use the buffer to repeat the previous frame image. . Therefore, the inserted frame is exactly the same as the image of the previous frame. For still images, because the picture of each frame is...
