Abstract

The invention relates to single use cameras. In particular it relates to a single use camera that incorporates a motion sensor. The motion sensor enables automatic activation of various camera features and utilities. These include the automatic activation of such normal camera actions as shutter release and the taking of a photograph, activation of a flash unit either to aid in the taking of a photograph or as a warning or signaling device and activation of an incorporated audible alarm.

Claims

1. A one time use camera comprising a light sensitive photographic element characterized in having a photographic sensitivity of greater than ISO 100 and an exposure latitude greater than about 2.1 log E, and an accelerometer which activates said camera to take a picture after motion is detected by exposure of said element for less than about 1/100 second, wherein said accelerometer detects accelerations between about 0.005 and 500 g.

2. The camera of claim 1 further comprising means to adjust at least one of the motion sensitivity and the activation threshold of the accelerometer.

3. The camera of claim 1 further comprising means to mount said camera in a vehicle.

4. A camera according to claim 1 wherein said camera further comprises a lens for exposing said element, said lens characterized in having a focal length of between 4 and 100 mm and an aperture of between f/2 and f/32, wherein said element sensitivity is between ISO 100 and ISO 6400, said element exposure latitude is greater than 2.1 log E, and said element exposure is for between 1/100 and 1/500 second.

5. A camera according to claim 1 wherein said light sensitive element is chosen from the group consisting of a silver halide film and a semiconductor array.

6. A camera according to claim 1 wherein said accelerometer is integrally mounted to said camera.

7. A camera according to claim 1 wherein said accelerometer is a microaccelerometer.

8. A camera according to claim 7 wherein said microaccelerometer is a microfabricated sensor comprising a silicon substrate.

9. A camera according to claim 1 wherein said accelerometer is a microfabricated sensor comprising a silicon substrate integrally mounted to said camera.

10. A camera comprising a motion sensor and having a body defining camera body faces wherein said camera comprises at least two lenses and at least two shutter mechanisms disposed on opposing faces of said camera body, and wherein said shutter mechanisms are activated by said motion sensor.

11. The camera of claim 10 wherein said camera is a one-time use camera.

12. The camera of claim 10 further comprising means to adjust at least one of the motion sensitivity and the activation threshold of the motion sensor.

13. The camera of claim 10 wherein said motion sensor is integrally mounted to said camera, said camera is loaded with a film having a sensitivity greater than ISO 100 and the camera shutter enables exposure of said film for less than 1/100 second.

14. The camera of claim 10 wherein said motion sensor is integrally mounted to said camera, said camera comprises a semiconductor array having a picture taking sensitivity greater than ISO-100 and the camera shutter enables exposure of said array for less than 1/100 second.

15. The camera of claim 10 further comprising means to mount said camera in a vehicle.

16. The camera of claim 10 wherein said motion sensor is an accelerometer which detects accelerations between 0.005 and 500 g.

17. The camera of claim 10 wherein said motion sensor is chosen from the group consisting of magnetic, inductive and infrared proximity detectors.

18. The camera of claim 10 comprising four lenses and four shutter mechanisms.

19. A camera comprising a motion sensor which is an accelerometer which detects accelerations between about 0.005 and 500 g and an emergency flash enabling repetitive flashes having a duration of less than about one second and a flash frequency of at least one flash every ten seconds wherein said emergency flash is activated by said motion sensor after motion is detected.

20. The camera of claim 19 wherein said camera is a one-time use camera.

21. The camera of claim 20 wherein said motion detector activates the shutter device of said camera to take a picture.

22. The camera of claim 19 further comprising means to adjust at least one of the motion sensitivity and the activation threshold of the motion sensor.
