Patent ID: 7009653

Claim:
A photographing apparatus having a function of preventing a blur of a still image, the apparatus comprising: a photoelectric transduction unit for photoelectrical-transducing incident light from a lens; a pulse generation unit for outputting a charge extract pulse for extracting charge accumulated in the photoelectric transduction unit, and an erase pulse for erasing the accumulated charge; a diaphragm unit for controlling an amount of light incident on the photoelectric transduction unit; a diaphragm driving unit for controlling an open/close operation of the diaphragm unit; and a control unit for outputting, to the diaphragm driving unit, a first control signal to supply a driving voltage in a direction of opening the diaphragm unit, for outputting, to the diaphragm driving unit, a second control signal to supply the driving voltage in a direction of closing the diaphragm unit, and for controlling the operation of the photoelectric transduction unit, the pulse generation unit, and the diaphragm driving unit; wherein the diaphragm driving unit comprises: a diaphragm motor for opening and closing the diaphragm unit by imparting a rotational movement generated by a magnetic field to the diaphragm unit; and a diaphragm motor driving unit for controlling a direction of rotation and a speed of the diaphragm motor; and wherein the diaphragm motor comprises: a rotor connected to the diaphragm unit, and rotated in at least one of a forward direction and a backward direction under control of the diaphragm motor driving unit; an elastic member having one end connected to a fixed point and another end connected to the rotor for rotating the rotor in a direction for closing the diaphragm unit; a driving coil for generating a magnetic field to cause a rotational movement of the rotor in at least one of a direction for opening and a direction for closing the diaphragm unit; and damping means for preventing damping of the rotor.
