sticks_us writes with news of an Apple patent application, recently published by the USPTO, for an on-board camera system that would include circuitry for processing external infrared signals. The data received from these signals could then be used to present information to the user of the device, or even to modify the device's operation. "For example, an infrared emitter could be located in areas where picture or video capture is prohibited, and the emitter could generate infrared signals with encoded data that includes commands to disable the recording functions of devices. An electronic device could then receive the infrared signals, decode the data and temporarily disable the device's recording function based on the command. ... In some embodiments, a device may apply a watermark to detected images as an alternative to completely disabling a recording function."
