Abstract: A lighting model storage unit (205) stores therein a lightning model in which a light source is provided to a model body. A parts selection unit (203) reads an outline shape stored in an outline information storage unit (201) and selects a combination of parts to be arranged to the outline shape from the parts images stored in the parts storage unit (202). A map storage unit (204) stores therein a map where the selected parts are arranged to the outline shape. A lightning model applying unit (206) applies a lightning model matching the map. An image drawing section (207) draws a three-dimensional image on the map where the parts are arranged by combining the cooler components from the light source according to the applied lighting model.
