DIGITAL SINGLE-LENS REFLEX CAMERA
First Claim
1. A digital single lens reflex camera with an imaging sensor and a return mirror, the camera comprising:
- a focusing section that performs focus detection based on a contrast scheme using the imaging sensor;
a motion detecting section that detects a speed of the subject based on an image on the imaging sensor; and
a control section that performs camera shake correction according to the speed of the subject detected in the motion detecting section,wherein the focusing section, the motion detecting section and the control section enter operation mode while the return mirror is retracted from the optical axis.

Abstract
A digital single-lens reflex camera is configured for making it possible to reduce deterioration in image quality due to a camera shake or an object movement and to easily pick up an image with a good image quality. In a digital single-lens reflex camera (1), when an object speed is detected on the basis of a detected object movement, a body microprocessor (12) judges if the object speed is equal to a threshold value (A) or more and, if it is smaller than the threshold value (A), controls a conversion lens camera shake correcting device (82) in a conversion lens (2) or a camera body shake correcting device (75) in a camera body (3) to carry out the camera shake correction. Further, if the object speed is equal to or more than the threshold value (A), the body microprocessor (12) makes a digital signal gain setting unit (111) high in gain so as to increase the ISO sensitivity or makes a shatter speed faster to set a shorter exposure time and has a plurality of images continuously picked up under different exposure conditions.
