PROBLEM TO BE SOLVED: To provide a stroboscope device capable of executing normal light emission control with high accuracy. SOLUTION: A strobe light emitting tube 13 preliminarily emits light, prior to normal light emission at the time of taking a photograph, under the control of a CPU 8. Further, the CPU 8 calculates a relative emitted light quantity as the ratio of a emitted light quantity in the normal light emission to a specified reference emitted light quantity, based on a value obtained in such a manner that the light which is reflected by a subject, because of the preliminary light emission is photoelectrically converted by a CCD 3 and data stored in a ROM 16 for storing a file of a combination of the array of plural relative emitted light quantities increased or decreased by a geometric series and the light emission time needed to obtain the emitted light quantity in the normal light emission corresponding to each of the plural relative emitted light quantities, and controls the light emission time in the normal light emission corresponding to the calculated relative emitted light quantity. |
