PROBLEM TO BE SOLVED: To detect a blurred degree of an image in higher accuracy. SOLUTION: An edge map creation part 311 detects edge intensity of an image in an increment of a block having a predetermined size. An operation parameter adjusting part 313 sets an edge reference value used for extraction of an edge point that is a pixel used for detection of the blurred degree of the image based on a dynamic range that is a difference between the maximum value and the minimum value of the edge intensities. An edge point extracting part 315 extracts a pixel as the edge point with the edge intensity being equal to or greater than the edge reference value, and also the pixel value of a pixel within a block being included in an edge block that is a block within a predetermined range. This technology is applicable to, for example an image processing apparatus which detects the blurred degree of the image. COPYRIGHT: (C)2010,JPO&INPIT
