<P>PROBLEM TO BE SOLVED: To solve such problems that, when composing a virtual subject and a background image, both of them often have different color tones to create a feeling of strangeness, and conventionally, it is required to manually adjust rendering parameters, or the like from a rendering result, and it takes a time and labor. <P>SOLUTION: The image forming device composes a virtual subject and a background image, and generates a composite image. The image forming device includes: correction coefficient deriving means that renders an achromatic object disposed at a position where the virtual subject is placed and derives a correction coefficient using an environment map representing information of a light source in the periphery of the virtual subject; background image correcting means that corrects the background image on the basis of the derived correction coefficient; and composing means that composes the corrected background image and the virtual subject using the environment map. <P>COPYRIGHT: (C)2013,JPO&INPIT |
