<p><P>PROBLEM TO BE SOLVED: To provide a mosaic reduction method of an image that reduces visibility in a zipper effect and can be mounted without the complication of hardware. <P>SOLUTION: The adaptive mosaic reduction method for interpolating each pixel position is provided by separately considering degree of change (for example, other standards of gradient, Laplacian, or the degree of change) in both of horizontal and vertical directions on at least two color planes. Adaptive mosaic reduction algorithm uses a voting system to decide an interpolation direction at each pixel position. Each color plane votes for horizontality or verticality based on the comparison between vertical and horizontal constituents of the degree of change on the color plane. In one embodiment, the voting is counted according to measurement obtained by the pixel position itself and also from a close pixel. <P>COPYRIGHT: (C)2003,JPO</p> |
