    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 136 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 139. A calculation circuit 127 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: A device for processing an image signal that can improve an image quality of a zoom image, in which based on an input image signal, an image-signal-processing section produces an output image signal to display the zoom image with an expansion rate of an image being changed consecutively around an arbitrary center point specified by the user. Each pixel data of the output image signal is calculated by using coefficient data produced by a coefficient production circuit that produces the coefficient data based on not only phase information of each pixel but also resolution adjustment information and noise suppression degree adjustment information that the image quality adjustment information generation circuit generates based on the expansion rate of the image, a change rate (K) of the expansion rate of the image, and characteristics information of the image.
