A motion calculation buffer stores the motion information values for each pixel/block; and a motion calculation unit corrects the motion information values of the input nth field stored in the motion calculation buffer unit, based on the motion information values of the n+1th field. Thus, it is possible to quickly and correctly detect motion regions and still regions in a moving image by a relatively simple method of correcting the motion information values while suppressing a spurious still region occurrence in a currently interpolated field.
CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Korean Application No. 2002-74277, filed Nov. 27, 2002, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
SUMMARY OF THE INVENTION Therefore, the present invention provides an apparatus and method for easily and quickly detecting motion regions and still regions of a moving picture without the occurrences of spurious still regions in the current field to be interpolated.
BRIEF DESCRIPTION OF THE DRAWINGS The above and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
FIG. 3 is a flow chart of detecting motion in an input motion picture using the motion detection apparatus shown in FIG. 1 in accordance with an embodiment of the present invention. Referring to FIG. 3, at operation 300, initializing processing is performed. In other words, the motion detection unit 100 is sequentially input with a plurality of fields that are temporally successive, and assuming an incoming field to be an nth field (fn), based upon an n−1th field (fn−1) and an n+1th field (fn+1) immediately before and after the incoming field (fn), at operation 301, the motion detection unit 100 detects motion information values representing presence or absence of motion for each pixel/block of the nth field (fn). Typically, at operation 301, it is possible to detect the motion information value for each pixel/block, on the basis of the preceding field and the succeeding field immediately before and after the nth field (fn), from difference values for the pixels between pixels/blocks at a corresponding location in the preceding field and the succeeding field, or a summed value of absolute values of a difference between the pixel values for each block. The motion information value is expressed as a certain value indicating the presence or absence of the motion in a corresponding pixel/block, for example, as a �1� in a case where the motion is present in the corresponding pixel/block, or as a �0� in a case where the motion is absent in the corresponding pixel/block.
In Formula (1), V (i, j) represents the fetched motion information value for jth pixel on line ith, and T1 represents the first value set. The first value may be set at random/arbitrary and may be set, for example, to the number �4�.
In Formula (2), V (i, j) represents the motion information value for jth pixel on line ith, and T2 represents the second value set. Similar to the first value, the second value may be set at random/arbitrary and may be set, for example, to the number �1�. According to an aspect of the invention, typically, T1 and T2 are random numbers within a predetermined range according to image processing application. Typically, the first demultiplexer 161 in the motion calculation unit 150 performs operation 302. Further, the adding operation 304 or the subtracting operation 308 is performed by the adder 151 or the subtracter 153, respectively, in the motion calculation unit 150.
