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 acquisition unit that acquires an image specified by a user;
• a first search unit that searches for a region satisfying conditions where the acquired image can be assigned;
• a first assignment unit that assigns the acquired image to the region searched for by the first search unit;
• a dividing unit that further divides any one of regions to which no image is assigned into a plurality of regions when there is no region satisfying the conditions where the acquired image can be assigned as a result of the search by the first search unit;
• a second assignment unit that assigns the acquired image to a region satisfying the conditions where the acquired image can be assigned among the plurality of regions formed by the division by the dividing unit;
• and
• a presentation unit that, on the basis of the assignment by the first assignment unit or the second assignment 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 acquisition step of acquiring an image specified by a user;
• a first search step of searching for a region satisfying conditions where the acquired image can be assigned;
• a first assignment step of assigning the acquired image to the region searched for in the first search step;
• a dividing step of further dividing any one of regions to which no image is assigned into a plurality of regions when there is no region satisfying the conditions where the acquired image can be assigned as a result of the search in the first search step;
• a second assignment step of assigning the acquired image to a region satisfying the conditions where the acquired image can be assigned among the plurality of regions formed by the division in the dividing step;
• and
• a presentation step of, on the basis of the assignment in the first assignment step or the second assignment 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 acquisition unit that acquires an image specified by a user;
• a first search unit that searches for a region satisfying conditions where the acquired image can be assigned;
• a first assignment unit that assigns the acquired image to the region searched for by the first search unit;
• a dividing unit that further divides any one of regions to which no image is assigned into a plurality of regions when there is no region satisfying the conditions where the acquired image can be assigned as a result of the search by the first search unit;
• a second assignment unit that assigns the acquired image to a region satisfying the conditions where the acquired image can be assigned among the plurality of regions formed by the division by the dividing unit;
• and
• a presentation unit that, on the basis of the assignment by the first assignment unit or the second assignment unit, causes a mosaic image in which the acquired image is placed to be presented.
