摘要： An NTSC signal is supplied to a first area extracting circuit and a second area extracting circuit. The first area extracting circuit extracts class taps from the NTSC signal. The second area extracting circuit extracts predictive taps from the NTSC signal. The first area extracting circuit extracts pixels in predetermined positions from same phase pixels as a considered pixel. Based on level differences between extracted pixels, a pattern detecting section performs a class categorization. A class code determining section generates class codes based on the result of the class categorization and supplies the generated class codes to a coefficient memory. The coefficient memory outputs pre-stored predictive coefficients based on the class codes to a predictive calculating section. The predictive calculating section performs a sum of product calculation of pixel data as predictive taps received from the first area extracting circuit and the predictive coefficients received from the second area extracting circuit and generates for example a component signal Y with the result of the sum of product calculation.

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.
