Abstract

A control method and an electronic device are provided. The method comprises: after establishing a connection between the first electronic device and a second electronic device, determining a device type of the second electronic device; based on the device type of the second electronic device as well as a correspondence between device types and output modes, determining a target output mode of the first electronic device that corresponds with the device type of the second electronic device; and displaying data via a display output unit of the first electronic device in the target output mode, wherein the displayed data corresponds to contents displayed by a display unit of the second electronic device, said contents being transmitted from the second electronic device to the first electronic device.

First claim

What is claimed is:

1 . A control method for a first electronic device comprising a display output unit, comprising:
after establishing a connection between the first electronic device and a second electronic device, determining a device type of the second electronic device; based on the device type of the second electronic device as well as a correspondence between device types and output modes, determining a target output mode of the first electronic device that corresponds with the device type of the second electronic device; and displaying data via the display output unit of the first electronic device in the target output mode, wherein the displayed data corresponds to contents displayed by a display unit of the second electronic device, said contents being transmitted from the second electronic device to the first electronic device.

2 . The control method according to claim 1 , wherein determining a device type of the second electronic device further includes:
generating a display image based on the contents transmitted from the second electronic device; matching the display image with a plurality of image templates to determine an image template matching the display image, wherein at least one image template is provided for each device type; and determining the device type of the second electronic device to be a device type corresponding to the image template matching the display image.

3 . The control method according to claim 2 , after determining the device type of the second electronic device to be a device type corresponding to the image template matching the display image, further including:
establishing a mapping relationship between the second electronic device and the device type of the second electronic device; and storing the mapping relationship.

4 . The control method according to claim 3 , before generating a display image based on the contents transmitted from the second electronic device, further including:
searching for the device type of the second electronic device in a pre-stored mapping relationship between electronic devices and device types; and when the device type of the second electronic device is not found,
generating the display image based on the contents transmitted from the second electronic device,
matching the display image with the plurality of image templates to determine an image template matching the display image, wherein at least one image template is provided for each device type, and
determining the device type of the second electronic device to be the device type corresponding to the image template matching the display image.

5 . The control method according to claim 3 , before generating a display image based on the contents transmitted from the second electronic device, further including:
searching for the device type of the second electronic device in a pre-stored mapping relationship between electronic devices and device types; and when the device type of the second electronic device is found, determining the device type of the second electronic device, and completing a process of the determining the device type of the second electronic device.

6 . The control method according to claim 1 , wherein the correspondence between device types and output modes includes at least one of:
a correspondence relationship between computer-type devices and a full-screen display mode; and a correspondence relationship between mobile-phone-type devices and a first display mode.

7 . The control method according to claim 1 , wherein the display output unit of the first electronic device includes a display unit, and displaying the data via the display output unit in the target output mode further includes:
displaying the contents transmitted from the second electronic device via the display unit in the target output mode.

8 . The control method according to claim 1 , wherein the display output unit in the first electronic device includes a projection module, and displaying the data via the display out unit in the target output mode further includes:
projecting, by the projection module, the contents transmitted from the second electronic device to a projection area in the target output mode.

9 . The control method according to claim 3 , wherein establishing a mapping relationship between the second electronic device and the device type of the second electronic device further includes:
providing the second electronic device with a device identification number, and establishing the mapping relationship between the device identification number of the second electronic device and the device type of the second electronic device.

10 . The control method according to claim 9 , before generating a display image based on the contents transmitted from the second electronic device, further including:
selecting the device identification number of the second electronic device as a search criterion; and based on the search criterion, searching for the device type of the second electronic device in the pre-stored mapping relationship between electronic devices and device types.

11 . An electronic device, comprising:
a communication module; a display output unit for outputting data; a memory for storing computer programs and operation data; and a processor for:
controlling the communication module to establish a connection with a second electronic device,
determining a device type of the second electronic device after the communication module establishes the connection with the second electronic device,
based on the device type of the second electronic device as well as a correspondence between device types and output modes, determining a target output mode that corresponds with the device type of the second electronic device, and
displaying data via the display output unit in the target output mode,
wherein the displayed data corresponds to contents displayed by a display unit of the second electronic device, said contents being transmitted from the second electronic device to the first electronic device.

12 . The electronic device according to claim 11 , wherein when the processor determines a device type of the second electronic device after the communication module establishes the connection with the second electronic device, the processor;
generates a display image based on the contents transmitted from the second electronic device; matches the display image with a plurality of image templates and determine an image template matching the display image, wherein at least one image template is provided for each device type; and determines the device type of the second electronic device to be a device type corresponding to the image template matching the display image.

13 . The electronic device according to claim 12 , after the processor determines the device type of the second electronic device to be a device type corresponding to the image template matching the display image, the processor further:
establishes a mapping relationship between the second electronic device and the device type of the second electronic device; and stores the mapping relationship.

14 . The electronic device according to claim 13 , wherein when the processor determines the device type of the second electronic device, the processor:
searches for the device type of the second electronic device in a pre-stored mapping relationship between the electronic devices and the device types; and if the device type of the second electronic device is not found, the processor further generates the display image based on the contents transmitted from the second el
