An image taking apparatus is provided with a lens driving unit that includes a magnetic shaft in which the S pole and the N pole are alternately aligned in a longitudinal direction of the shaft. The device also determines, based on the CDMA capacityresource information, a resource availability associated with the CDMA RAN, and determines, based on the capacity and the resource availability associated with the CDMA RAN, a CDMA RAN resource allocation. Output rendering is performed a frame at a time, and each frame is rendered in a time determined by the amount of processing defined by the process tree.
