[0074] like image 3 As shown, a first embodiment of the image sharing method of the present invention is proposed, and the method includes the following steps:

[0075] S11. The sending end detects whether the screen image has changed.

[0076] When two terminals establish a WFD connection, one terminal is the sender (Source), which is used to send the shared data to the outside, and the other terminal is the receiver (Sink), which is used to receive and output the shared data.

[0077] Optionally, a WFD connection may be established by multiple terminals, wherein one terminal is the transmitting end and the other terminals are the receiving ends; or, one of the terminals is the receiving end and the other terminals are the transmitting ends.

[0078] The aforementioned terminal may be a mobile terminal such as a mobile phone and a tablet, or may be a large-screen device such as a TV set and a monitor.

[0079] The sender can detect whether the screen image has changed in t...

Embodiment 2

[0093] like Figure 4 As shown, an image sharing method according to a second embodiment of the present invention is proposed, and the method includes the following steps:

[0094] S21. The sender determines whether the user has enabled the power saving function. When the power saving function is turned on, enter the power saving mode, and execute step S23; when the power saving function is not turned on, do not enter or exit the power saving mode, and execute step S22.

[0095] Users can turn on or turn off the power saving function at any time before establishing a WFD connection, after establishing a WFD connection, or even during the screen image sharing process.

[0096] Optionally, the transmitting end may add a power saving function switch option in the setting menu, and the user can enter the setting menu interface at any time, and enable or disable the power saving function in the setting menu interface.

[0097] Optionally, the sender may receive a user instruction...

Embodiment 3

[0106] like Figure 5 As shown, an image sharing method according to a third embodiment of the present invention is proposed, and the method includes the following steps:

[0107] S31. The sender determines whether the currently shared file is a continuously playing file. When the file is played continuously, the power saving mode is entered, and step S32 is executed; when the file is not played continuously, the power saving mode is not entered or exited, and step S33 is executed.

[0108]In this embodiment, the sending end can automatically enter or exit the power saving mode by intelligently judging the type of the currently shared file. Since the screen of the continuously playing file such as the video file is continuously changing, therefore, when the type of the currently shared file is a video file or other continuous playing file, the power saving mode is not entered or exited, and step S32 is executed; When the type of the file is a non-continuously playing file su...

Abstract

The invention discloses an image sharing device and an image sharing method. The device comprises a sensing module used for sensing whether a screen image changes, and a sending module used for sending the screen image to a receiving end when the screen image changes. Therefore, only when the screen image changes, the screen image is sent to the receiving end once, and when the screen image keeps static, the sending end does not send the screen image to the receiving end; compared with a way of continuously sending the screen image in the prior art, a data interaction frequency between the sending end and the receiving end is greatly reduced, so that power consumption of a terminal is greatly reduced, and the technical problem that the terminal is large in power consumption when sharing the image is solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an image sharing device and method. Background technique [0002] Wireless Fidelity Display (Wi-Fi Display, WFD) technology is a technology that enables a transmitter such as a smartphone and a notebook to wirelessly connect to a receiver such as a TV and a monitor. In the process of image sharing through WFD, the sending end continuously sends the screen image of the local machine to the receiving end, and the receiving end also continuously receives the screen image and reproduces the screen image on the screen of the local machine. [0003] Since the sender and receiver continue to send and receive data, and data exchanges are frequent, the power consumption is extremely large, which makes the power consumption of portable terminals such as smartphones and notebooks consume a lot, which greatly reduces the battery life, thus affecting the use of users. e...
