Image processing device and recording medium

An image processing apparatus, comprising:

• an edge detection unit that detects an edge from an input image, the input image having been read by an image reading unit that scan-reads an image;
• and
• smoothing unit that carries out a plurality of smoothing processings, and in the smoothing processing, said smoothing unit selects one smoothing condition from a plurality of smoothing conditions, which have been determined in advance and which include a region to be processed which is smaller than the input image, an amount of movement of the region to be processed, and a range of scanning in the input image, and on the basis of the selected smoothing condition, said smoothing unit smoothes an interior of the region to be processed in the input image, in which the edge is not detected, while moving and scanning the region to be processed within the range of scanning by the amount of movement,
• wherein each of the plurality of smoothing conditions includes,
• a filter size parameter for indicating a size of the region to be processed,
• an overlap parameter for indicating a width of an overlapped region of the region to be processed and a region to be processed after movement by the amount of movement, and
• an offset parameter for indicating a distance from an end portion of the input image to an end portion of the range of scanning.

A computer readable recording medium on which a program for executing processings is recorded, said program comprising:

• detecting an edge from an input image which has been read by an image reading unit that scan-reads an image;
• and
• carrying out a plurality of smoothing processings, and in the smoothing processing, a smoothing condition is selected from a plurality of smoothing conditions, which have been determined in advance and which include a region to be processed which is smaller than the input image, an amount of movement of the region to be processed, and a range of scanning in the input image, and on the basis of the selected smoothing condition, smoothing an interior of the region to be processed in the input image, in which the edge is not detected, while moving and scanning the region to be processed within the range of scanning by the amount of movement,
• wherein each of the plurality of smoothing conditions includes,
• a filter size parameter for indicating a size of the region to be processed,
• an overlap parameter for indicating a width of an overlapped region of the region to be processed and a region to be processed after movement by the amount of movement, and
• an offset parameter for indicating a distance from an end portion of the input image to an end portion of the range of scanning.
