Abstract:
A strobe emission apparatus, comprising:a strobe light emitter that sequentially emits strobe light at different color temperatures;a single charge accumulator that outputs an electric charge to the strobe emitter;a voltage detector that detects a terminal voltage of said single charge accumulator;a detector that measures an amount of light of an object to be photographed;a color temperature detector that measures a color temperature of ambient light;a first system controller that sets an emission ratio of said strobe light emitter so that a resultant color temperature of said strobe light emitter corresponds to said ambient light color temperature detected by said color temperature detector, said first system controller being arranged to control said strobe light emitter so as to maintain said emission ratio of said strobe light emitter;a second system controller that sets a maximum light emission amount defined by a predetermined threshold value where a first strobe light emission is controlled in order to enable subsequent strobe light emissions, thus obtaining a desired color temperature from a plurality of strobe light emissions having different color temperatures; andan emission controller that terminates an emission of said strobe light emitter when one of: (I) an amount of light measured by said detector reaches a predetermined value, and (ii) an emission of said strobe light emitter reaches said maximum light emission amount when said predetermined threshold value is detected;wherein the predetermined threshold value corresponds to the maximum light amount of the first emission from the strobe light emitter, and residual electric charge in the single charge accumulator drives subsequent emissions.
