Method and apparatus for disrupting an autofocusing mechanism
First Claim
1. Apparatus for disabling an automatic focusing mechanism which emits a signal toward a subject and receives a signal reflected from the subject in order to calculate a distance to the subject, the device comprising:
- a distortion generator which generates a distortion signal in the same frequency range as the emitted signal, such that the automatic focusing mechanism receives both the reflected signal and the distortion signal.

Abstract
An automatic anti-focusing mechanism which generates and emits one or more distortion signals includes one or more sound or light generators which generate the distortion signals in various portions of their respective spectrums. The emitted distortion signals are received by an active automatic focusing camera and inhibit the ability of the active automatic focusing camera to properly detect a signal reflected off of a subject. Accordingly, the ability of the active automatic focusing camera to properly focus upon a subject is severely limited or disabled.

17. A method of disabling an automatic focusing mechanism comprising:
-
(a) the automatic focusing mechanism emitting a first signal toward a subject;
(b) the automatic focusing mechanism receiving a second signal reflected from the subject;
(c) the automatic focusing mechanism using the second signal to calculate a distance to the subject; and
(d) the automatic focusing mechanism generating a distortion signal in the same frequency range as the first signal, such that the automatic focusing mechanism receives both the second signal and the distortion signal. - View Dependent Claims (18, 19, 20, 21, 22, 23)
