ABSTRACT:
The present invention discloses a photographing apparatus having the function of preventing blur of a still image. A diaphragm unit controls the amount of light incident on a photoelectric transduction unit from a lens. A diaphragm driving unit controls an open/close operation of the diaphragm unit. When opening the diaphragm unit, a control unit outputs to the diaphragm driving unit a control signal for supplying a driving voltage in a direction of opening the diaphragm unit. When closing the diaphragm unit, the control unit outputs to the diaphragm driving unit a control signal for supplying the driving voltage in a direction of closing the diaphragm unit. Moreover, power supplied to the diaphragm unit is controlled without requiring a special mechanical shutter, thereby reducing the time from an open state to a close state of a diaphragm. As a result, it is possible to prevent a blur of the image generated due to movement of a subject or shaking of the photographer's hands.
