Relighting has been used in many image productions. Relighting requires object shape information and reflectance, and previously one had to manually retouch the image or use special equipment. We therefore present a novel system for relighting with Kinect, which is a relatively inexpensive depth camera. First, we capture target objects and calculate their shapes. We then estimate reflectance from illumination that is calculated from an environment map taken at the same place. Finally, we relight the object using new illumination. The direction and intensity of the light can be adjusted by the user. This system enables the user to relight objects without complicated operations or expensive equipment.
