Abstract
A method and system for determining camera positioning information from an accelerometer mounted on a camera. The accelerometer measures the orientation of the camera with respect to gravity. Orientation measurement allows user interface information to be displayed in a “right side up” orientation on a viewfinder for any camera orientation. Alternatively, an artificial horizon indicator may be displayed in the viewfinder. The accelerometer may also measure camera movement. Camera movement information together with camera orientation can be used to determine camera usage. Additionally, camera movement information can be used to determine a minimum shutter speed for a sharp picture.
