Abstract

An image as a basis of a mosaic image is segmented into M×N areas by the process shown in FIG. 4 (S300), and the image characteristics of the segmented areas (S301), and those of source images (S305) are obtained. When the source image is a moving image, the image characteristics of that moving image are obtained from those of a plurality of still images in the moving image (S304). Source images corresponding to the segmented areas are determined (S309) and pasted (S310), thus generating a mosaic image.

Claims

1. An image processing apparatus capable of forming a mosaic image by combining source images, comprising:

storage means for storing a plurality of source images, including still images and moving images;

segmentation means for segmenting an image serving as a basis of the mosaic image into M×

N tiles;

characteristic extraction means for obtaining image characteristics of the tiles segmented by said segmentation means;

selection means for selecting a source image, from said storage means, corresponding to each of the segmented tiles on the basis of the image characteristics obtained by said characteristics extraction means;

generation means for generating the mosaic image by pasting the source images selected by said selection means onto the tiles segmented by said segmentation means without overlapping the pasted source images; and

playback means for, if a moving image is pasted as a source image onto the tiles, repetitively playing back the moving image on the tile.

2. The apparatus according to claim 1, wherein when the source image is a moving image, the characteristic extraction means obtains an image characteristic of the moving image from image characteristics of a plurality of still images in the moving image.

3. An image processing method for forming a mosaic image by combining source images, comprising the steps of:

storing in a storage means a plurality of source images, including still images and moving images;

segmenting an image serving as a basis of the mosaic image into M×

N tiles;

a characteristic extracting step of obtaining image characteristics of the segmented tiles;

selecting a source image from said stored source images corresponding to each of the segmented tiles on the basis of the image characteristics obtained by said characteristic extracting step;

generating the mosaic image by pasting the source images selected by said selection step onto the segmented tiles without overlapping the pasted source images; and

a playback step of, if a moving image is pasted as a source image onto the tiles, repetitively playing back the moving image on the tile.

4. The method according to claim 3, wherein when the source image is a moving image, an image characteristic of the moving image is obtained from image characteristics of a plurality of still images in the moving image.
