Abstract:
The control apparatus of the present invention determines a motion state of an object and provides an IRLED switching control signal suitable for the motion state in an apparatus for sensing/recognizing a motion of the object by using an infrared light-emitting diode (IRLED) and a photodiode (PD). Such a control apparatus is an LED driving control apparatus, and includes a motion velocity generating unit, a previous section average value generating unit, a state value generating unit, a control unit, and an LED switching control signal generating unit.
