[0036] The present invention will be further described below in conjunction with the drawings.
[0037] Such as Figure 1~3 As shown, a method for doubling the frame rate based on image contour matching includes the following steps:
[0038] (1) Compare the current frame with the reference frame to determine the moving area and still area in the current frame;
[0039] (2) Perform edge detection on the moving area to determine the current contour of the image;
[0040] (3) According to the determined current contour, generate the current block containing the contour, match the search area in the reference frame, and match the search area with the current block according to the block matching criterion;
[0041] (4) Detect whether a block similar to the current block is matched, if not, execute step (5), if yes, execute step (6);
[0042] (5) Interpolate using frame repetition or black frame insertion;
[0043] (6) Calculate the image data in the interpolated frame of the current bl...
