Filed: 2007-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem wherein technical skills for avoiding out-of-focus (bluntness) state and an indent of an edge is hard to be realized due to an excessive calculation volume, because enlarged size of an image is apt to generate the out-of-focus (bluntness) state and the indent of the edge by a conventional linear interpolation method.  <P>SOLUTION: Results of edge detections in the horizontal direction and in the vertical direction are compared. With regard to a pixel decided as having continuity, a smooth enlarged image is obtained as for an oblique line which causes jagginess by an enlarging processing by a linear interpolation conducted, by filtering the continual mutual pixels. By varying the number of a filter tap according to ratios of frequency components constituting the numbers of pixel and the images which are continual, flexibility of selecting filter characteristics is increased and optimum filter characteristics are obtained.  <P>COPYRIGHT: (C)2009,JPO&INPIT
