Method and apparatus for disrupting digital photography
A method and apparatus for disrupting digital photography uses one or more infrared, LED-based light sources that emit light generally not visible to the human eye yet readily detected by digital imaging equipment. Such detected infrared light disrupts the quality of an image that is obtained from a semi-conductor-based light detector and digitally recorded. Thus, digitally-recorded images are disrupted without disrupting live viewing of such images.
1 . A theater, comprising:
a stage area;
a viewing area comprising a plurality of seats arranged generally facing toward the stage area; and
a digital photography disruption system comprising an infrared light source adapted to direct infrared light generally outwardly from the stage area and at sufficient intensity to be detected by a semiconductor-based light sensor in the viewing area.
2 . The theater of claim 1 , wherein the infrared light source comprises a light emitting diode (LED).
3 . The theater of claim 2 additionally comprising an optical component adapted to spread infrared light from the infrared light source over a broad viewing angle.
4 . The theater of claim 2 , wherein the stage area comprises a cinema screen.
5 . The theater of claim 4 , wherein the infrared light source is positioned adjacent the screen.
6 . The theater of claim 4 , wherein at least one LED is disposed on or in the screen.
7 . The theater of claim 4 , wherein at least one LED is disposed behind the screen.
8 . The theater of claim 7 , wherein the at least one LED is adapted to pulse according to a pulsing sequence.
9 . The theater of claim 8 , wherein the pulsing sequence comprises a random sequence of pulse frequencies.
10 . The theater of claim 8 , wherein the at least one LED is mounted on a movable mount.
11 . The theater of claim 10 , wherein the mount moves according to a movement sequence.
12 . The theater of claim 11 , wherein the pulsing sequence and movement sequence are electronically directed by a controller.
13 . The theater of claim 8 additionally comprising a second infrared LED spaced apart from the at least one LED.
14 . The theater of claim 4 additionally comprising an infrared LED adapted to direct infrared light onto the screen.
15 . The theater of claim 2 , wherein the at least one LED is positioned in the stage area.
16 . The theater of claim 15 , wherein the at least one LED is disposed on the stage set of a live theater production.
17 . A screen viewing facility, comprising:
a stage area comprising a screen;
a viewing area generally adjacent the seating area and accommodating viewing of the screen; and
a digital photography disruption system comprising an infrared light source adapted to direct infrared light onto the screen at sufficient intensity to be detected by a semiconductor-based light sensor that is in the viewing area and is directed toward the screen.
18 . The theater of claim 17 , wherein infrared light is directed onto at least a portion of the screen at an intensity greater than an intensity of visible light projected onto the screen.
19 . The theater of claim 17 , wherein the infrared light source comprises an infrared laser.
20 . The theater of claim 17 , wherein the infrared light source comprises a plurality of infrared light-emitting diodes (LEDs) positioned to direct light at the screen.
21 . The theater of claim 20 , wherein the infrared light source is attached to a heat sink.
22 . The theater of claim 20 , comprising first and second infrared light sources that are spaced apart from one another, the first and second light sources comprising LEDs that are positioned to direct light at the screen, the first and second sources adapted to simultaneously direct light at a target portion of the screen.
23 . A method of disrupting digital photography of a subject, comprising:
providing a source of electromagnetic radiation substantially outside of the visible electromagnetic spectrum;
positioning the radiation source on or adjacent the subject; and
directing the invisible electromagnetic radiation from the source toward a viewer of the subject;
wherein the electromagnetic radiation is provided at an intensity sufficient to be detected by a semiconductor light sensor, but is substantially invisible to a viewer of the subject.
24 . The method of claim 23 additionally comprising providing an optical member adapted to direct the light from the source across a broad viewing angle.
25 . The method of claim 23 , wherein the source emits radiation according to a random pulse frequency sequence.
26 . The method of claim 25 , wherein the source emits infrared radiation.
27 . The method of claim 26 , wherein the source comprises a light emitting diode (LED).
