Abstract: Example adaption apparatus are described. An example adaption apparatus includes a first USB interface and a second USB interface. A power signal of the first USB interface is electrically connected to a power signal of the second USB interface. A first channel configuration signal of the first USB interface is electrically connected to an ID signal of the second USB interface using a first resistor. The ID signal of the second USB interface is electrically connected to the power signal of the second USB interface using a second resistor. A resistance value of the first resistor meets a criterion followed by a first device to identify a UFP device according to the USB Type-C protocol. A sum of the resistance value of the first resistor and a resistance value of the second resistor meets a criterion followed by the first device to identify a DFP device according to the USB Type-C protocol.

Abstract: An electronic device photographing method includes, after the electronic device enters a photographing screen, determining a folding angle of the flexible display screen based on a pixel coordinate parameter of a photographed object on the photographing screen; and/or determining target luminance of a display screen; and when detecting that a photographing button is pressed, adjusting luminance of the display screen to the determined target luminance. In this way, when the electronic device is used to take an image, fill-in light can be implemented for the photographed photo by improving target luminance of the display screen based on the pixel coordinate parameter of the photographed object on the photographing screen.
