ABSTRACT:
In order to allow a quantitative measurement of the operation of an image blurring correction function by adding an effective test function to a camera, an image blurring correction mechanism detects the shaken states of the camera with respect to two orthogonal axes around the photographing optical axis of the camera. The image blurring correction mechanism is arranged in the optical path between a photographing lens and a film and has two axes of freedom corresponding to the above two axes. An external communication (control) terminal is used for external communication with a main microcomputer in the camera. When a test mode command is externally input to the camera via the external communication terminal, a sub-microcomputer in a shake compensation circuit performs specific operation control, through the main microcomputer, to execute a shake compensation function with respect to the image blurring correction mechanism.
