    摘要: 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 (525i signal) is converted into an output image signal Vout (such as 1080i signal, XGA signal, or 525i signal 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 y1 to 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.

    摘要: 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, is converted into an output image signal, Vout that has different format and/or size therefrom. A class code, CL, is obtained from tap data extracted from the Vin and corresponding to each pixel (pixel at a target position) within a unit pixel block, which constitutes Vout. Product-sum device 137 generates the coefficient data, ai0 to ai8, in the upper layered production equation in each class according to the lower layered production equation using coefficient seed data, bij0 to bij8, of each class and resolution information, g and f, during vertical blanking period, while it generates the coefficient data, Wi, in the estimated equation, according to the upper layered production equation during effective vertical scanning period using the coefficient data, ai0 to ai8, in connection with the class code CL and phase information, h and v. A calculation circuit 127 provides pixel data, y, at the target position according to the estimated equation using the tap data, xi, corresponding to the target position and the coefficient data, Wi, obtained by the product-sum device 137.
