Digital camera
First Claim
1. A digital camera comprising:
- an automatic exposure control mechanism that is performed in an automatic exposure mode which at least is comprised of two sub-modes, such as a normal program mode and high-shutter-speed priority program mode, wherein said high-shutter-speed priority program mode selects higher shutter speed when it is compared with said normal program mode under a same photographing condition;
a camera attitude sensing processor that senses an attitude of said camera from the vertical;
a camera-shake detecting processor that detects a camera-shake in accordance with a stability of said attitude, sensed by said camera attitude sensing processor; and
a selecting control processor that selects said high-shutter-speed priority program mode as said sub-mode, when said attitude, sensed by said camera attitude sensing processor, is unstable and said camera-shake is detected by said camera-shake detecting processor while said automatic exposure mode is performed.

Abstract
A digital camera with an anti-blur function is provided with simple structures. The digital camera comprises an automatic exposure control mechanism for an automatic exposure mode and inclinometer. As sub-modes, the automatic exposure mode comprises a normal program mode and a high-shutter-speed priority program mode. Output of the inclinometer is repeatedly checked at a predetermined period to detect camera-shake. Camera-shake is determined by stable or unstable output from the inclinometer. When the output is unstable, it is determined that camera-shake exists, and the high-shutter-speed priority program mode is selected. Contrarily, when it is stable, it is determined that no camera-shake exists, and the normal program mode is selected. Attitude of the camera, which is sensed by the inclinometer, is recorded to a detachable PC card with the image data when camera-shake is not detected. If camera-shake is detected, the sensed attitude data is invalidated.
