INTERPOLATION USING AT LEAST ONE BOUNDARY POINT IN BOUNDARY SURFACE

摘要

PPROBLEM TO BE SOLVED: To provide color spatial conversion and interpolation with which the granularity of an image is reduced while restricting a dark coloring agent in a dark region. PSOLUTION: In a first color space (200), an instruction (800) of a target point is received (1910). In a second color space, a set of interpolation points (870-873) in the first color space for interpolating a value of said target point are identified (1920). The set of interpolation points includes at least one interpolation point (872) on a boundary surface (1020) determined by a coloring agent boundary. PCOPYRIGHT: (C)2005,JPO&NCIPI
