ABSTRACT:
A vibration compensation mode selection apparatus and associated visual display for a camera which allows a photographer to enable or disable a vibration compensation unit while receiving visual feedback regarding the operation state of the vibration compensation unit and information regarding the vibrations detected within the camera. A vibration detection unit is provided to output a signal indicating the amount and direction of vibrations experienced by the camera. A vibration compensation unit drives the vibration compensation lens perpendicular to the optical axis of a photographic lens system to correct for the vibrations detected by the vibration detection unit. A button is provided on the front face of the camera to enable the photographer to disable the vibration compensation unit by pressing the button. A display unit is provided to indicate to the photographer whether the vibration compensation system has been enabled or disabled. For example, the display unit can be configured to flash at a high frequency when the vibration compensation unit has been disabled. Further, the display unit can be configured to provide information regarding the severity of the vibrations detected within the camera. Specifically, the display unit can be configured to steadily illuminate to indicate vibrations which can be corrected by the vibration compensation system, and at a slow rate to indicate vibrations which are outside the correctable range of the vibration compensation unit. The display unit can either be provided within the viewfinder or on the body of the camera in a location easily visible by the photographer.
