Patent ID: 7701484

Claim:
A digital still camera comprising: a sensitivity setting device that sets an image-capturing sensitivity; a photographing device having an image-capturing element that receives a light flux transmitted through a photographic lens and executes photoelectric conversion on the received light flux; a photometric circuit which measures brightness of a field; a shutter speed calculation circuit which calculates a first shutter speed according to the image-capturing sensitivity set by the sensitivity setting device and the photometric result from the photometric circuit; a control device that operates the photographing device at the first shutter speed; a vibration quantity detection circuit that detects a vibration quantity of the camera; an image blur calculation device that calculates an image blur quantity at the time of photographing operation based on the first shutter speed and the vibration quantity of the camera detected by the vibration quantity detection circuit, prior to the photographing operation; and a determination device that makes a decision as to whether the image-capturing sensitivity needs to be adjusted based upon the image blur quantity calculated by the image blur calculation device, wherein: the sensitivity setting device adjusts the image-capturing sensitivity if the determination device determines that the image-capturing sensitivity needs to be adjusted; and if the image-capturing sensitivity is adjusted, a second shutter speed is calculated according to the adjusted image-capturing sensitivity and the photometric result from the photometric circuit; and the control device operates the photographing device at the second shutter speed.
