IMAGE PROCESSING DEVICE, IMAGE DISPLAY DEVICE, IMAGE PROCESSING METHOD, AND DATA STRUCTURE OF IMAGE FILE

摘要

An original image to be edited is displayed using hierarchical data (136). When a user draws a graphic (132) in an area (130) of the image wherein the area is an edition target, an image data update unit generates a hierarchically-structured layer (134) made of only the area (130) in which drawing is performed (S10). Specifically, the image in the edition target area (130) becomes the lowermost layer, and images of upper layers are generated by appropriately reducing the size of the image in the lowermost layer, so as to form hierarchical data. Upon displaying an image, if it is confirmed that the updated area (130) is contained in a frame (138) which is to be newly displayed, the image of the layer (134) is displayed by overlapping the image of the layer on the image of the original hierarchical data (136) (S12).
