Patent ID: 8159601

Claim:
A sequential shooting controller, comprising: a high load drive mode that drives a device used in an image capturing operation under a relatively high load condition; a low load drive mode that drives said device under a relatively low load condition; a first power-voltage detector that detects a voltage of an electric power source by connecting a load for monitoring the voltage of said electric power; and a second power-voltage detector that detects the voltage of said electric power source by monitoring the voltage applied to said device; said first power-voltage detector being actuated in the beginning or sequential shooting, which continuously carries out sequential image capturing operations, before a first image capturing operation starts; an image capturing operation under said high load drive mode being started when the voltage of said power source detected by said first power-voltage detector is higher than a first threshold value and an image capturing operation under said low load drive mode being started when the voltage of said power source detected by said first power-voltage detector is lower than said first threshold value; and said second power-voltage detector being driven during an image capturing operation under said high load drive mode is carried out and said second power-voltage detector being disabled while an image capturing operation under said low load drive mode is carried out.
