Abstract
Abstract Using an image processing apparatus for carrying out general interpolation processing which can freely adjust a frequency response characteristic regardless of an enlargement or reduction ratio, an image whose frequency response characteristic almost agrees visually with the frequency response characteristic of an optimal diagnostic image obtained by interpolation processing of another kind can be easily obtained. The image processing apparatus comprises conversion means for converting the characteristic of interpolation processing by first enlargement or reduction processing means to a characteristic corresponding to that of interpolation processing by second enlargement or reduction processing means so that a visible image reproduced by a network printer almost agrees visually with a visible image reproduced by a CR printer, in terms of the enlargement or reduction ratio and the response characteristic.
