Apparatus and method for preventing a picture from being taken by flash photography
First Claim
Patent Images
1. An apparatus for obscuring a photographic image comprising, in combination:
- a triggering mechanism which will generate a signal when detecting a light signal from a camera flash; and
a flash unit coupled to the triggering mechanism for generating a counteracting flash after receiving the signal generated by the triggering mechanism for saturating an image field of the camera with light to obscure the photographic image.

Abstract
An apparatus and method for preventing a photographic image from being taken has a triggering mechanism which will generate a signal when detecting a light signal indicative of a camera flash. A flash unit is coupled to the triggering mechanism for generating a counteracting flash after receiving the signal generated by the triggering mechanism. By generating a counteracting flash a very short time after detecting the flash, the apparatus saturates an area of the camera'"'"'s image field during the camera'"'"'s exposure period. Thus the image in that area is obscured.
