<P>PROBLEM TO BE SOLVED: To provide a photographing device to which an illuminator for photography capable of emitting flash light can be connected and which achieves improvement of efficiency. <P>SOLUTION: The photographing device (100) to which the illuminator for photography (300) capable of emitting flash light can be connected includes: a decision part (71) for deciding whether or not shutter time satisfies shutter totally opening time when the entire surface of an imaging part (10) is exposed to subject light simultaneously based on the set shutter time; a light-emitting efficiency decision part (73) for obtaining light-emitting efficiency showing a ratio of effective emitted light quantity contributing to exposure in the shutter totally opening time to total emitted light quantity when the illuminator for photography emits the flash light based on the shutter totally opening time, if the decision part decides that the shutter time satisfies the shutter totally opening time; and a light emission decision part (74) for deciding whether or not the illuminator for photography emits the flash light in photographing based on the light-emitting efficiency obtained by the light-emitting efficiency decision part. <P>COPYRIGHT: (C)2010,JPO&INPIT |
