PURPOSE: A camera module is provided to apply a high voltage to the shutter coil of a shutter. CONSTITUTION: A control unit(30) receives a shutter drive request signal from outside. The control unit outputs a control signal for the application of the drive power source of a shutter. A switch(50) receives the signal of the control unit. The switch applies the power source to the shutter through switching on. A charge pump(40) boosts the voltage of the power source applied to a shutter coil(70). A constant-current module(60) regularly keeps a current applied to the shutter coil.
