1. 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 control device that engages the photographing device in operation at a shutter speed corresponding to the image-capturing sensitivity set by the sensitivity setting device;
an image blur calculation device that calculates an image blur quantity indicating an extent to which an image becomes blurred during a photographing operation based upon the image-capturing sensitivity having been set 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, the control device engages the photographing device in operation at a shutter speed corresponding to the adjusted image-capturing sensitivity.

Abstract
Prior to a photographing operation, an image blur quantity indicating the extent to which the image becomes blurred during the photographing operation is calculated based upon an image-capturing sensitivity having been set, and a decision is made as to whether or not the image-capturing sensitivity needs to be adjusted based upon the calculated image blur quantity. If it is decided that the sensitivity level needs to be adjusted, the image-capturing sensitivity is adjusted and the photographing operation is executed at the shutter speed calculated based upon the adjusted image-capturing sensitivity.

8. An image blur correction apparatus comprising:
-
a sensitivity setting device that sets an image-capturing sensitivity; an image capturing command output device that outputs a signal for engaging an image-capturing element in photoelectric conversion at a shutter speed corresponding to the image-capturing sensitivity set by the sensitivity setting device; an image blur calculation device that calculates an image blur quantity indicating an extent to which an image becomes blurred during a photographing operation based upon the image-capturing sensitivity having been set, 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 when the image-capturing sensitivity is adjusted, the image capturing command output device outputs the signal to the image-capturing element to engage the image-capturing element in photoelectric conversion at the shutter speed corresponding to the adjusted image-capturing sensitivity. - View Dependent Claims (9)
