<P>PROBLEM TO BE SOLVED: To attain appropriate exposure amount by controlling the light emission quantity even at macro-photographing. <P>SOLUTION: A digital camera 2 is constituted of an imaging part 3, a stroboscopic apparatus 4, a CPU 5 and an operating part 6. The stroboscopic apparatus 4 is constituted of a strobe discharge tube 51, a light emitting capacitor 52, a charge control circuit 53, a voltage detection circuit 54, a discharge voltage adjustment circuit 55, a trigger circuit 56 and a power source 57. When a macro-photographing mode and also a strobe light emission mode are selected for the digital camera 2, the light emitting capacitor 52 is discharged by the discharge voltage adjustment circuit 55 so as to reduce the charge level of the light emitting capacitor 52. When a light emission control signal is transmitted from the CPU 5 to the trigger circuit 56, the charge voltage is already reduced in the light emitting capacitor 52, and the reduced discharge voltage flows into the strobe discharge tube 51 so as to emit the strobe light. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
