Camera with acceleration sensor
First Claim
1. A method for determining a state of utilization for a camera comprising:
- a. providing the camera, the camera including an accelerometer for determining an orientation of the camera with respect to the direction of gravity and a peak-to-peak acceleration magnitude over a given time duration;
b. determining when the axis of the camera lens is substantially aligned with the direction of gravity using the accelerometer;
c. determining a peak-to-peak acceleration magnitude over the given time duration using the accelerometer; and
d. identifying the state of utilization of the camera based at least in part on the determination of when the axis of the camera lens is substantially aligned with the direction of gravity and the determination of the peak-to-peak acceleration magnitude over the given time duration.

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.
