US Patent 8363010 Operating input device for reducing input error

An operating input device is provided in which input errors can be prevented. A finger area image is extracted from an image captured by a camera. A fingertip area is extracted from a difference image generated between the finger area image and a shifted image. A fingertip position is detected from the fingertip area based on a center of mass. A semitransparent fingertip image is superimposed on the menu image. Manual operation buttons coinciding with fingertip positions are displayed in an emphasized manner. An actual position of a finger press is shifted to coincide with a manual operation button position and the manual operation button is considered to be pressed.
