Abstract: Example camera use methods and apparatus are described. One example includes receiving a first message including an application ID or an application sub-function ID. When a type corresponding to the first message is a first type, a first processing result having a first message type is outputted along a first path through the first interface. When a type corresponding to the first message is a second type, a second processing result having a second message type is outputted along a second path or a third path through the first interface. A second message is received, which includes another application ID or another application sub-function ID. When a type corresponding to the second message is the first type, a third processing result having the first message type is outputted along the first path through the first interface.

Abstract: The method includes: A first electronic device sends a probe frame to an external camera; in a process in which the external camera approaches the first electronic device, a communication module in the external camera is powered on; the external camera obtains the probe frame; in response to the probe frame, the external camera starts a camera module in the external camera; and the external camera sends a response frame to the first electronic device, where the response frame is a reply to the probe frame. In the process in which the external camera approaches the first electronic device, the camera module in the external camera is started.
