Abstract
A technique includes detecting a power transition of a processor-based system and controlling operation of a camera of the processor-based system based on the detection of the power transition. Controlling the operation of the camera includes triggering a process to disable the camera in response to detection of the power transition.
Claims15
A method comprising:
- detecting a power transition of a processor-based system;
- and
- controlling operation of a camera of the processor-based system based on the detection of the power transition, wherein controlling the operation of the camera comprises triggering a process to disable the camera in response to detection of the power transition.
An apparatus comprising:
- a shutter to control light through a camera lens;
- and
- a controller to:
- receive a power signal representing a power state of an electronic device;
- and
- control the shutter in response to the power signal.
3 more elements
An apparatus comprising:
- a camera lens;
- an active glass cell having a first state to block transmission of light through the camera lens and a second state to allow transmission of light through the camera lens;
- a switch to toggle the active glass cell between the first state and the second state;
- a processor being associated with a plurality of power states;
- a power manager to transition the processor among the power states and provide a signal representing a current power state among the plurality of power states associated with the processor;
- and
- a circuit to control whether the active glass cell is in the first state and whether the active glass cell is in the second state based on a state of the switch and the signal provided by the power manager.
