Image providing device, image processing method, image processing program, and recording medium

An image providing device for providing a mosaic image of an original image divided into a plurality of regions, the image providing device comprising:

• an image acquisition unit that acquires an image specified by a user;
• a candidate determination unit that, on the basis of color information of the acquired image and color information of the regions, determines the regions to be candidates for a region to which the acquired image is assigned;
• an edge degree acquisition unit that acquires edge degrees indicating degrees of edges in the regions determined as the candidates;
• an assignment determination unit that, on the basis of the acquired edge degrees, determines the region to which the acquired image is assigned from the regions determined as the candidates;
• and
• a presentation unit that, on the basis of assignment determined by the assignment determination unit, causes a mosaic image in which the acquired image is placed to be presented.

An image processing method in an image providing device for providing a mosaic image of an original image divided into a plurality of regions, the image processing method comprising:

• an image acquisition step of acquiring an image specified by a user;
• a candidate determination step of, on the basis of color information of the acquired image and color information of the regions, determining the regions to be candidates for a region to which the acquired image is assigned;
• an edge degree acquisition step of acquiring edge degrees indicating degrees of edges in the regions determined as the candidates;
• an assignment determination step of, on the basis of the acquired edge degrees, determining the region to which the acquired image is assigned from the regions determined as the candidates;
• and
• a presentation step of, on the basis of assignment determined in the assignment determination step, causing a mosaic image in which the acquired image is placed to be presented.

A non-transitory recording medium in which an image processing program is computer-readably recorded, the image processing program causing a computer, which is included in an image providing device for providing a mosaic image of an original image divided into a plurality of regions, to function as:

• an image acquisition unit that acquires an image specified by a user;
• a candidate determination unit that, on the basis of color information of the acquired image and color information of the regions, determines the regions to be candidates for a region to which the acquired image is assigned;
• an edge degree acquisition unit that acquires edge degrees indicating degrees of edges in the regions determined as the candidates;
• an assignment determination unit that, on the basis of the acquired edge degrees, determines the region to which the acquired image is assigned from the regions determined as the candidates;
• and
• a presentation unit that, on the basis of assignment determined by the assignment determination unit, causes a mosaic image in which the acquired image is placed to be presented.
