<P>PROBLEM TO BE SOLVED: To suppress blurring of an edge when mosquito noise is removed. <P>SOLUTION: A first edge strength is calculated from a first region including a focus pixel as a processing target in an input image and surrounding pixels. A second edge strength is calculated from a second region which is smaller than the first region. A filter is determined such that a smoothing strength obtained in a case where the first edge strength is higher than a reference and the second edge strength is lower than the reference is higher than a smoothing strength obtained in other cases. The determined filter is used for filter processing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
