Automatic engagement of image stabilization
First Claim
1. An image stabilized digital image capture device, comprising:
- an image sensor for capturing a digital image;
an optical system for imaging a scene onto the image sensor;
an image stabilization system;
an exposure control system;
a memory system; and
a processor for performing the steps of;
determining exposure settings using the exposure control system, wherein the determined exposure setting includes an exposure time;
selectively engaging the image stabilization system responsive to whether the determined exposure settings satisfy a predefined condition, wherein the image stabilization system is not engaged when the exposure time is less than a threshold exposure time Tt given by Tt=K/F, where F is the focal length of the optical system and K is a predefined constant;
capturing a digital image of a scene using the image sensor and the selectively engaged image stabilization system; and
storing the captured digital image in the memory system.

Abstract
An image stabilized digital image capture device, comprising an image sensor for capturing a digital image; an optical system for imaging a scene onto the image sensor; an image stabilization system; an exposure control system; a memory system; and a processor. The processor is used to perform the steps of determining exposure settings using the exposure control system; selectively engaging the image stabilization system responsive to whether the determined exposure settings satisfy a predefined condition; capturing a digital image of a scene using the image sensor and the selectively engaged image stabilization system; and storing the captured digital image in the memory system.
