主权项 1. A photographing apparatus, comprising: an imaging section accumulating photoelectric current according to a received light amount and outputting an image signal according to this accumulated photoelectric current; an accumulation control section controlling an accumulation operation in the imaging section; a flashlight emission section illuminating an object by flash light emission; an emitted light waveform storing section preliminarily storing emitted light waveform information which shows a relationship between a light emission time and a light emission strength in the flash light emission section and represents a light emission strength corresponding to a light emission time; an exposure calculation section calculating an accumulation time in the imaging section and a reception light amount corresponding to a required light emission amount of the flash light emission in the flash light emission section by the imaging section; and an accumulation start timing setting section setting a timing of accumulation start in the imaging section from the light emission start in the flash light emission section based on an output of the emitted light waveform storing section and the reception light amount corresponding to a required light emission amount of the flash light emission output by the exposure calculation section, wherein the accumulation control section instructs the flash light emission section to start flash light emission and also causes the imaging section to start the accumulation based on the accumulation start timing output by the accumulation start timing setting section from the flash light emission start in the flash light emission section, the emitted light waveform information has information on a light emission strength for each of a plurality of intervals, and the accumulation start timing setting section calculates, based on the emitted light waveform information, a light emission amount obtained by accumulating the light emission strength for each of the intervals which correspond to a period within the accumulation time when setting the accumulation time in association with the light emission time in the flash light emission section, and sets the timing of accumulation start so that a sum total of the light emission amounts calculated for each of the intervals within the accumulation time is the same as the received light amount.
