Abstract
Disclosed is a camera provided with a strobe system. The strobe system includes a capacitor to be charged. Charging voltage of the capacitor can be detected through an output terminal. The output terminal can be electrically connected and disconnected to and from the capacitor by a switching element. The circuit has an input terminal which receives a control signal. In response to the control signal, charging operation is enabled, and at the same time, the switching element is controlled to connect the output terminal to the capacitor. While, if the charging voltage has reached an upper limit, the charging operation is disabled and the output terminal is disconnected from the capacitor for a predetermined period of time by changing the status of the control signal.
