Abstract
The present patent application discloses a reactuating device for a strobe having brightness level detecting apparatus for detecting the brightness level of an object to be photographed to determine whether or not flash illumination is necessary, and (or) charging-incompletion detecting apparatus for detecting that the storage capacitor in the strobe is not fully charged, whereby when the brightness level of the object becomes so low that strobe photography is necessary, and (or) when the strobe is not fully charged, as soon as this is detected, a charging of the strobe begins.
