ABSTRACT:
The present invention relates to an information signal processor and the like preferable for use in the case of converting a format of an image signal or converting an image size. An input image signal Vin (525isignal) is converted into an output image signal Vout (such as1080isignal, XGA signal, or525isignal for obtaining an image to be displayed in a different magnification). A class code CL is obtained from tap data selectively extracted from the Vin and corresponding to each pixel (pixel at a target position) within a unit pixel block, which constitutes Vout. A coefficient production circuit produces coefficient data for each class, which is used at the time of calculating the pixel data at the target position, based on the coefficient seed data for each class and position information h, v about the target position generated in a position information generation circuit. A calculation circuit provides pixel data y1to yp of the target position according to the estimated equation using the tap data xi corresponding to the target position and the coefficient data Wi corresponding to the class code CL.
