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.
