Information signal processing apparatus, picture information converting apparatus, and picture displaying apparatus

摘要

A 525i (interlace) signal can be converted into a 1050i signal or a 525p (progressive) signal. A calculating circuit (34) generates pixels of an output picture signal with a linear estimation expression of predictive taps received from a first tap selecting circuit (31) and a coefficient received from a coefficient memory (38). The coefficient memory (38) stores coefficients pre-obtained for individual classes. A class is determined by combining a spatial class corresponding to spatial class taps received from a second tap selecting circuit (32) and motion class taps received from a third tap selecting circuit (33). A line sequential converting circuit (39) converts a scanning line structure of an output signal of the calculating circuit (34) and provides 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 (44) to the coefficient memory (38) and registers (40 - 43).
