Abstract
Described techniques enable thwart detection for warning lights associated with recording devices, such as cameras. A warning light may be used to alert bystanders that a recording is in progress, but an operator of a recording device may attempt to circumvent the warning light by obstructing the warning light. A lightpipe or other light guiding element may be used to guide a redirection of the warning light to a light sensor. Then, when the redirection exceeds a threshold, which may be determined based in part on a baseline level of ambient light, recording operations of the recording device may be automatically deactivated.
Claims20
A device comprising:
- a recording device;
- a warning light configured to be activated in conjunction with recording operations of the recording device;
- a light sensor configured to detect redirection of the warning light when the warning light is at least partially obscured;
- and
- a control circuit configured to deactivate the recording operations in response to the redirection.
A computer program product, the computer program product being tangibly embodied on a non-transitory computer-readable storage medium and comprising instructions that, when executed by at least one computing device, are configured to cause the at least one computing device to:
- activate a warning light of a device in conjunction with activating recording operations of a recording device of the device;
- detect redirection of the warning light at a light sensor of the device when the warning light is at least partially obscured;
- and
- deactivate the recording operations in response to the redirection.
A method comprising:
- activating a warning light of a device in conjunction with activating recording operations of a recording device of the device;
- detecting redirection of the warning light at a light sensor of the device when the warning light is at least partially obscured;
- and
- deactivating the recording operations in response to the redirection.
