摘要： JPEG encoded data are entropy-decoded to quantized DCT coefficients which are sent to a prediction tap extraction circuit (41) and to a class tap extraction circuit (42). The prediction tap extraction circuit (41) and the class tap extraction circuit (42) extract what is needed from the quantized DCT coefficients to form prediction taps and class taps. A classification circuit (43) effects classification based on the class taps. A coefficient table storage unit (44) sends tap coefficients corresponding to the classes resulting from the classification to a sum of products circuit (45), which sum of products circuit (45) then effects linear predictive calculations, using the tap coefficients and the class taps, to generate decoded picture data.

A moving class determining circuit 5 generates a moving class with SD data extracted by an area extracting circuit 4. A class code generating circuit 6 generates a class code with the spatial class and the moving class. A tap decreasing ROM 7 supplies additional code data for each class code to a tap decreasing code 10. The additional code data is used to decrease taps of SD data. The tap decreasing circuit 10 decreases the SD data extracted by an area extracting circuit 9. A prediction calculating circuit 11 receives coefficient data corresponding to the class code from a ROM table 8 and obtains HD data with the decreased SD data corresponding to a linear prediction equation.

摘要： An interlaced input picture signal having a field frequency of 50 Hz is supplied. A class detecting circuit detects a class corresponding to a pattern of a level distribution of input pixels in the vicinity of an output pixel to be generated. A predictive coefficient set corresponding to the class is read from a predictive coefficient memory. Sum-of-product calculating circuits calculate data of an output picture signal using a linear estimating expression of predictive taps (pixels of an input picture signal) and predictive coefficient sets. The sum-of-product calculating circuits output pixel values M and S of an output picture signal having a field frequency of 50 Hz. The pixel values M and S that are output from the sum-of-product calculating circuits are converted into a signal having a frequency of 60 Hz by respective field memories. A selector alternately selects outputs of the field memories and generates an output picture signal (having a field frequency of 60 Hz).

摘要： An input digital image signal (SD signal) is converted into a high resolution digital video signal (HD signal). A considered pixel is categorized as a class corresponding to a one-dimensional, two-dimensional, or three-dimensional level distribution of a plurality of reference pixels of the SD signal. A predicted value of the considered pixel is generated by linear combination of values of a plurality of pixels of the SD signal adjacent to the considered pixel of the HD signal and predicted coefficients that have been learnt. In the learning process, predicted coefficients are determined by linear combination of the values of pixels of the SD signal and the predicted coefficients so that the sum of squares of the predicted value and the true value is minimized. Instead of the predicted coefficients, representative values may be determined for each class. In this case, the representative values are used as predicted values corresponding to the class of the input SD signal. Examples of the representative values are a base value of a block and a value normalized by dynamic range DR.
