Classification: H04N

Abstract:
1. An image data processing apparatus, comprising: first selection means for selecting a candidate motion compensating vector including a pixel of a noticed region of image data from a plurality of candidate motion compensated vectors added to the image data and for producing a shift amount of the pixel of the noticed region, and a shift amount detection characteristic amount based on the candidate motion compensating vector; classification means for extracting a pattern of a block boundary based on the shift amount of the pixel of the noticed region and the shift amount detection characteristic amount, and for classifying the pixel of the noticed region into one of a plurality of classes based on the pattern of the block boundary; second selection means for selecting a prediction coefficient based on the one of the plurality of classes into which the pixel of the noticed region has been classified by said classification means; construction means for constructing, based on the shift amount of the pixel of the noticed region and the shift amount detection characteristic amount, a prediction tap of the noticed region, the prediction tap being a pixel at an end point of the selected candidate motion compensating vector; and arithmetic operation means for arithmetically creating an intermediate frame based on the selected prediction coefficient and the prediction tap.
