IMAGE GENERATION DEVICE, IMAGE GENERATION METHOD, IMAGE GENERATION PROGRAM, AND RECORDING MEDIUM

摘要

Disclosed is an image generation device which generates a mosaic image suitable for viewing by a user even before sufficient images for completing the mosaic image have been acquired. Image regions at which images are drawn are specified on a per segmented region unit basis in each of a plurality of layers that are respectively divided into a plurality of segmented regions. Acquired images are allocated to segmented regions within the image regions of any of the layers on the basis of color information of the acquired images and color information of the respective segmented regions within the specified image region. Images allocated within image regions of two or more layers from among the plurality of layers are overlapped between layers, and a mosaic image is generated, said two or more layers being layers at which images are allocated to at least one of either the segmented regions or the segmented regions of other layers at display locations that overlap the aforementioned segmented regions, for all of the segmented regions within the image regions of each respective layer.
