Abstract:
1. An electronic apparatus, comprising: a circuit system, arranged for controlling an operation of the electronic apparatus; a camera sensing circuit, coupled to the circuit system, the camera sensing circuit arranged for sensing at least a portion of a portrait of a user; and an object sensing circuit, coupled to the circuit system, the object sensing circuit arranged for sensing object(s) around the electronic apparatus, wherein an operation of the object sensing circuit is different from an operation of the camera sensing circuit; wherein the camera sensing circuit is used for determining whether to notify the circuit system to switch from a first operation mode to a second operation mode, and the object sensing circuit is used for determining whether to notify the circuit system to switch from the second operation mode to the first operation mode; the camera sensing circuit is coupled between the circuit system and the object sensing circuit; when the object sensing circuit determines that a distance between the object and the electronic apparatus is changed by sensing an object distance, the object sensing circuit notifies the circuit system through the camera sensing circuit for switching the circuit system from the second operation mode to the first operation mode.
