The appearance control system is one of the visual feedback control systems that can manipulate the appearance of an object by using a projector-camera system. This system processes the captured image and projects the image on the object overlappingly for manipulating the appearance in real time. However, the afterimage is caused by a part of the image which is not overlapped on the object and remains in capture range of the camera. Therefore, this afterimage makes the appearance control system unstable. In this paper, we propose a new projection algorithm that can compensate the time delay for the appearance control system.We verify the effectiveness of our algorithm which can suppress the influence of the afterimage against the time delay in the visual feedback loop.
