Abstract: An electronic device comprises a display apparatus, a photographing apparatus, and a lifting apparatus. The photographing apparatus receives, through the first channel or a second channel, a first stream on instruction triggered by a first application. The second channel is a channel between the display apparatus and the photographing apparatus, and the first stream on instruction is used to instruct the photographing apparatus to collect an image and output the collected image to the first application. The photographing apparatus reports a first stream on state to a proxy module in the display apparatus through the first channel. The proxy module in the display apparatus controls, based on the first stream on state, the lifting apparatus to lift the photographing apparatus. The photographing apparatus after being lifted starts to collect an image, and outputs the collected image to the first application through the second channel.

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.
