Detecting encoded signals under adverse lighting conditions using adaptive signal detection
First Claim
1. A non-transitory computer readable medium comprising instructions stored thereon that when executed by one or more processors, cause a portable device comprising a camera for capturing data representing imagery or video, a radio frequency (RF) transceiver, a touchscreen display, a graphical user interface for providing a user interface on the touchscreen display, to perform the following:
- obtain data representing imagery or video provided by the camera;
obtain lighting information via the graphical user interface, the lighting information associated with the captured data representing imagery or video;
adapt an encoded signal detector based on the lighting information, in which the adapted encoded signal detector is configured to detect whether a signal is encoded within the data representing imagery or video.

Abstract
Signal detection adaptable to accommodate various lighting conditions, and to detect embedded signals according to anticipated lighting conditions likely to be present during image capture. A portable apparatus comprising: a camera for capturing data representing imagery or video; a touchscreen display; means for communicating and receiving data; means for obtaining data representing imagery or video, the imagery or video having been captured with said camera; means for obtaining lighting information associated with image capture of the imagery or video, in which the lighting information is associated with a light level or color temperature; and means for processing the data representing imagery or video to determine whether a signal is encoded therein, in which said means for processing utilizes obtained lighting information to determine whether the signal is encoded in the data representing imagery or video. Additional disclosure, combinations and claims are also provided.
