ABSTRACT:
An image deflection preventing device for a camera, such as a still camera which is used to drive a deflection preventing optical system in accordance with readings from angular velocity sensors and other circuitry. Moreover, an exposure mode selection device is included to select strobe photography according to the focusing distance from a distance measuring unit maintained in the camera to a subject to be photographed. The selection device can select strobe photography when the focusing distance is closer than a predetermined distance or when photographic magnification from a focal length detection unit to a subject to be photographed is greater than a predetermined value. The selection of strobe photography is done using results from a photometric unit in conjunction with the determination of a brightness level. In particular, if a given brightness level is equal to or greater than a predetermined value, strobe photography is selected, otherwise, exterior light photography is selected. The brightness level for selection of strobe photography is typically higher at closer distances, longer focal lengths, or larger photographic magnifications.
