ABSTRACT:
An apparatus for detecting camera shaking includes an accelerometer mounted in a camera for sensing acceleration to produce an electrical signal representative of the acceleration sensed, an alarm indicator for indicating an alarm, and control circuitry connected to the accelerometer for comparing the electrical signal with a threshold level. The control circuitry is operative in response to release of a shutter of the camera to enable the alarm indicator when the electrical signal exceeds the threshold level. The indicator thereby indicates the possibility of blur due to shaking of the camera in an image taken.
For the accelerometer, a micromechanical acceleration sensor may be used, in which changes in electrostatic capacitance caused by acceleration applied are derived in the form of electrical signals.
