Abstract
There is provided an imaging system including a camera and a control host. The camera identifies ambient light intensity and performs trigger event detection in a low power mode. When the camera detects a trigger event in the low power mode, the control host is woken up. The camera also determines an exposure mode according the ambient light intensity and informs the exposure mode to the control host such that an operating mode of the control host after being woken up matches the exposure mode of the camera.
