摘要： A signal converting apparatus and a signal converting method which predictively produce highly accurate interpolated pixels in accordance with a classification which precisely reflects a variety of signal characteristics of inputted video signals to provide a high resolution video signal. An activity is evaluated and classified for each block of an inputted video signal (S.sub.1), and stepwise classifications are executed on each block of the inputted video signal (S.sub.1) in accordance with an activity code (c0) obtained as a result of the activity classification. In this way, the accuracy of subsequent classifications can be increased, reflecting the activity characteristic of each block of the inputted video signal (S.sub.1), thus achieving, as a whole, a highly accurate classification of the inputted video signal (S.sub.1). Appropriate prediction coefficients (d1) are read based on the activity code (c0) and a class code (c1) for each block of the inputted video signal (S.sub.1) to produce highly accurate interpolated pixels, thus providing a high resolution video signal (S.sub.2).

摘要： A 525i (interlace) signal can be converted into a 1050i signal or a 525p (progressive) signal. A calculating circuit generates pixels of an output picture signal with a linear estimation expression of predictive taps received from a tap selecting circuit and a coefficient received from a coefficient memory. The coefficient memory stores coefficients pre-obtained for individual classes. A class is determined by combining a spatial class corresponding to spatial class taps received from a tap selecting circuit and motion class taps received from a tap selecting circuit. A line sequential converting circuit converts a scanning line structure of an output signal of the calculating circuit 34 and obtains an output picture signal. The output picture signal is designated with a conversion method selection signal. Information corresponding to the selection signal is loaded from an information memory bank to the coefficient memory and registers.
