Embodiment Construction

[0027] Please refer to figure 1 , figure 1 is a schematic diagram of an image processing device 100 according to an embodiment of the present invention. The image processing device 100 includes a storage circuit 105, a judgment circuit 110, and a generation circuit 115. The storage circuit 105 receives a plurality of input frames F_0-F_n, and these input frames F_0-F_n include a current frame F and a plurality of adjacent frames. frame Fadj (such as the previous frame and the next frame), the current frame F can be considered to be composed of multiple images with a smaller range, and each image with a smaller range can be regarded as the Part of the image in the current frame, in other words, the current frame F includes a plurality of partial images, and each adjacent frame Fadj is also composed of a plurality of images with a smaller range, and these images with a smaller range are in the The spatial positions respectively correspond to a plurality of partial images in th...

Abstract

The invention provides an image processing method and an image processing device. The image processing method comprises the steps of judging whether a sub-image in a partial image is a first image according to the partial image of a current picture frame and a corresponding image corresponding to the partial image in an adjacent picture frame; when the sub-image is not the first image, judging whether the sub-image is a second image or a third image according to the partial image and the corresponding image, wherein one of the first image and the second image is a still image; the other one is a mobile image, and the third image is an image of the sub-image near the adjacent image.

Description

technical field [0001] The invention relates to an image processing mechanism, in particular to an image processing method and an image processing device capable of thinning the motion information in a partial image to generate the motion information of each sub-image in the partial image. Background technique [0002] At present, the existing technologies are generally divided into two categories, one is to use the pixel-level motion adaptive detection (Per-pixel Motion Adaptive Detection) to realize the function of image deinterlacing on the display end, although this method is easy to implement, there are analysis If the window is too small, the motion logo will be inaccurate, and if the analysis window is too large, the hardware cost will be too high. The image quality is better, but the calculation logic of motion compensation is quite complicated, and its calculation cost is also high, which is not conducive to the realization of hardware. In addition, once the predict...
