The first processing mode is: the processing unit 112 of the treatment circuit 104 directly a part of content in effective demonstration data AA_0 of repeated original pictures picture F_IN is used as effective demonstration data AA_2 of the second image frame F2, for example, effectively show that data AA_2 can be the content that effectively shows the set of the multi-strip scanning line that is positioned at the first half in data AA_0, be positioned at the content of the set of the multi-strip scanning line of Lower Half, be positioned at the content of the set of the multi-strip scanning line of core, the content of the set of even number bar sweep trace in whole picture, the content of the set of arbitrary scan line in the interior perhaps whole picture of the set of odd number bar sweep trace in whole picture.
The second processing mode is: the processing unit 112 for the treatment of circuit 104 carries out interpolation processing (for example average treatment) by effective demonstration data AA_0 of original image F_IN and effective demonstration data of next original image F_IN ', and from interpolation result, chooses a part of content and be used as effective demonstration data AA_2 of the second image frame F2.
The third processing mode is: the processing unit 112 for the treatment of circuit 104 is by the processing that coincides of effective demonstration data AA_0 of original image F_IN and effective demonstration data of next original image F_IN ', and from the result that coincides, choose a part of content and be used as effective demonstration data AA_2 of the second image frame F2, for instance, can give respectively suitable blending ratio for effective demonstration data of effective demonstration data AA_0 of original image F_IN and next original image F_IN ', afterwards, produce via being added or subtracting each other to process the result that coincides again, , the processing unit 112 for the treatment of circuit 104 is the effective demonstration data AA_2 that pass look (dithering) concept and decide the second image frame F2 that process by coinciding.
The 4th kind of processing mode is: the processing unit 112 for the treatment of circuit 104 carries out specific image processing (adjustment, the adjustment of sharpness and/or the adjustment of brightness of the adjustment of for example contrast, the adjustment of saturation degree, gamma value) for effective demonstration data AA_0 of original image F_IN, and from processing result image, chooses a part of content and be used as effective demonstration data AA_2 of the second image frame F2.
