Claim Text:
1. A method of operating an electronic device having first and second imaging sensors, wherein the first imaging sensor has a higher framerate than the second imaging sensor, the method comprising: operating the first imaging sensor in an active mode in which the first imaging sensor captures video of a scene; with the first imaging sensor, monitoring the scene for a predefined stop criterion; with the first imaging sensor, detecting the predefined stop criterion in the scene; with control circuitry in the electronic device and based upon the detection of the predefined stop criterion in the scene, switching the first imaging sensor into a power-conserving standby mode; while the first imaging sensor is in the power-conserving standby mode, monitoring the scene for a predefined trigger criterion with the second imaging sensor; with the second imaging sensor, detecting the predefined trigger criterion in the scene; and with the control circuitry in the electronic device and based upon the detection of the predefined trigger criterion in the scene with the second imaging sensor, switching the first imaging sensor into the active mode in which the first imaging sensor captures video of a scene.
