ABSTRACT:
A camera with a shake detection function includes a shake detector for detecting a camera shake, a signal amplifier which performs a differential amplification based on an output of the shake detector and a voltage value output by a camera controller, while level-shifting its own amplified voltage, and a camera controller for controlling a shake detection in response to the output of the signal amplifier, and also for controlling an autofocus operation and a film advancing operation. The camera controller is provided with the functions of sampling the output voltage of the signal amplifier, comparing the sampled shake value with a predetermined value, and generating a predetermined analog voltage to be fed to the signal amplifier. The invention provides a camera with a simple, compact and high-accuracy shake detector without the need for a dedicated module.
