ABSTRACT:
In a shutter release device adapted for use with a photograpic camera, especially of the compact or miniature type, delay means are selectively actuated in accordance with a set or anticipated shutter speed for delaying or retarding the initiation of actual shutter opening. The shutter opening is commenced after a lapse of time from the manual operation of the shutter release button to the operation of the shutter release member, when the scene brightness is so low that a blurred picture is anticipated. The shutter is actuated immediately after operation of the release member when the scene brightness is high enough. The delay means may be a mechanical governor of an electric delay circuit responsive to shutter speed setting or detection of scene brightness.
