An apparatus for detecting movement of an object captured by an imaging device, the apparatus includes a moving object detection unit, that is (1) operable to detect movement of an object based on a first moving object detecting process, and (2) operable to detect movement of the object based on a second moving object detecting process. The apparatus also includes an output unit operable to generate an output based on the detection by the moving object detection unit based on at least one of the first and second moving object detecting processes.
