ABSTRACT:
An information signal processor that is well suitable for use in conversion of an SD signal into an HD signal. The pixel data set corresponding to an objective position in the HD signal is extracted selectively from the SD signal. Class CL to which pixel data set of the objective position belongs is then obtained using the pixel data set. A coefficient production circuit produces coefficient data sets Wi for each class based on coefficient seed data sets and values of picture quality adjusting parameters h and v. A tap selection circuit selectively extracts the data sets xi from the SD signal and then, a calculation circuit produces the pixel data sets of the objective position in the HD signal using the data sets xi and the coefficient data sets Wi. It is thus possible to save on the storage capacity of the memory.
