Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] See Figure 6 , Figure 6Schematic diagram of the structure of the frequency multiplication system 600 for increasing the frequency of image display in the present invention. The frequency multiplication system 600 includes a buffer device 610 , a motion estimation device 620 , an interpolation device 630 , a motion compensation device 640 and a control device 650 .

[0035] The buffer device 610 has an input terminal 611 and zeroth to fifth storage units, wherein the storage units are field buffers. The buffer device 610 receives image data of a first frame, a second frame, and a third frame, and these frames are composed of an odd field and an even field, and divide these frames into the zeroth field to the fifth field respectively. field is...

Abstract

The invention discloses a frequency increasing system for increasing image display frequency, which comprises a buffering device, a mobile estimating device, an interpolating device, a mobile compensating device and a controller, wherein the buffering device receives the image data of a first frame, a second frame and a third frame and stores all the image data in fields ranging from a zero fieldto a fifth field; the mobile estimating device estimates a mobile motion vector according to the fields; the interpolating device generates an interpolating field according to the fields; the mobile compensating device generates a sixth field and a seventh field according to the fields, the interpolating field and the motion vector stored in the buffering device; the controller is used for controlling the writing and reading of the buffering device. The frequency increasing system is characterized in that a fourth field corresponding to the sixth field and the seventh field is positioned between the first frame and the second frame on a display timeline.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a frequency-increasing system for increasing image display frequency. Background technique [0002] Frame Rate Up-Conversion (FRC, Frame Rate up-Conversion) is an emerging technical field, the main purpose is to increase the video frame rate (Frame rate) to meet the needs of modern high-quality TV, such as high-quality TV picture requirements The frequency may be 60Hz or higher. A video that becomes a high frequency frame by interpolating the frame from the original video source, e.g. increased from 30 frames per second to 60 frames per second. [0003] In frame interpolation, it is assumed that the nth frame (called F n ) and frame n+1 (called F n+1 ) to insert a frame (called F in ). A relatively simple way is the frame replay method (Frame repetition), such as figure 1 As shown, the practice is to frame F n Repeat twice to replace frame F in , although this in...
