Abstract
From a series of primary image signal components of an image signal representing an image, secondary image signal components, which correspond to an enlarged image or a reduced image and the number of which is different from the number of the primary image signal components, are obtained from predetermined interpolating operation formulas. Values of coefficients in the predetermined interpolating operation formulas, which values correspond to a desired sharpness of an enlarged image or a reduced image, are calculated from values of the coefficients in the predetermined interpolating operation formulas, which values are different from each other and which values correspond to enlarged images or reduced images having the same scale of enlargement or the same scale of reduction and having different sharpness. Secondary image signal components are then obtained from the predetermined interpolating operation formulas in which the coefficients are set to the values thus calculated.
