    摘要: An electronically controlled camera having a macro mode operating capability which is disabled in the event predetermined object-distance-information is not obtained which is required for automatically focusing the camera in the macro mode. In this event, the lens is automatically shifted from the macro position to a non-macro position to enable a properly focused photograph to be taken. The shifting of the lens is preferably performed in response to actuation of the shutter release button while the lens is in the macro position, without further actuation of the shutter release button. Further, the camera can be arranged to return the lens to a macro position after the photograph is taken.

    摘要: An apparatus for controlling a strobe which is used in a camera. The strobe control apparatus includes a charging time-limit selecting device for selecting one of plurality of charging times according to the operating conditions of the camera, and a charging voltage limit selecting device for selecting one of plurality of charge limit voltages according to the operating conditions of the camera. If the charged voltage of the strobe does not reach the selected charge limit voltage after the selected charging time has elapsed, charging is stopped. The strobe control apparatus also includes a charge prohibiting device for prohibiting charging if a predetermined charge prohibit time has not elapsed after charging is completed, so as to prevent damage to the strobe due to heat generated by frequent flashings. The predetermined prohibit time is changed, however, according to the sensed heat condition of the strobe.
