<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus, method and program, capable of detecting a degree of blurring of an image with further high accuracy. <P>SOLUTION: An edge map creation unit 11 detects an edge intensity of an input image in units of three types of blocks having different sizes. An operation parameter adjustment unit 13 sets initial values of an edge reference value and an extraction reference value on the basis of a dynamic range which is a difference between the maximum and minimum values of the edge intensity. An edge point extraction unit 15 extracts an edge point from the input image on the basis of the edge reference value. Until an extraction amount determination unit 16 determines that the edge point extraction amount is appropriate on the basis of the extraction reference value, the operation parameter adjustment unit 13 repeatedly performs a processing of adjusting the edge reference value, and the edge point extraction unit 15 repeatedly performs a processing of extracting the edge point from the input image on the basis of the adjusted edge reference value. This invention is applicable to an imager processing apparatus for detecting the degree of blur of an image. <P>COPYRIGHT: (C)2009,JPO&INPIT |
