Method of establishing connection between electronic devices

The present invention relates to a method for establishing a connection between electronic devices, and more particularly to a method for capturing a connection between electronic devices via a camera module to capture connection information included in a predetermined frame.

With the advancement of technology, the functions of electronic devices are becoming more and more powerful. Functions such as data sharing or remote control can be performed between the electronic devices via the Internet. Before the electronic device performs the above functions of data sharing or remote control, the electronic device must first establish a connection. For example, when a first electronic device is to be connected via a network and a second electronic device, the first electronic device must first obtain connection information of the second electronic device, for example, the second electronic device. One of the Internet Protocol (IP) addresses and one of the second electronic devices are connected to the information such as the number to further establish a connection with the second electronic device via the Internet.

However, the connection information of the electronic device cannot be automatically obtained. The user must directly query the connection information of the electronic device in the console of the operating system, and then perform connection setting to establish a connection between the electronic devices. The above process is quite complicated and is quite inconvenient for the user. In addition, if the user is unfamiliar with the operating system of the electronic device, the user cannot perform the above connection process by himself.

The present invention provides a method for establishing a connection between electronic devices, comprising: a first electronic device displaying a plurality of frames and a predetermined frame per time unit on a screen to generate a visual image, the predetermined frame including the first a connection information of an electronic device; a second electronic device captures the plurality of frames and the predetermined frame via a photographic module; and the second electronic device includes the connection information according to the predetermined frame via the Internet The network establishes a connection with the first electronic device.

Compared with the prior art, the present invention inserts a predetermined frame of connected information in a plurality of frames displayed per time unit, and enables the electronic devices to automatically pass through the Internet without affecting the original image visually. The network is connected without the need for manual setting by the user, which greatly increases the convenience of use.

Please refer to both Figure 1 and Figure 2. FIG. 1 is a schematic diagram of a first electronic device 100 displaying a plurality of frames fo and a predetermined frame fp per time unit on a screen 110 to generate a visual image f.

For example, the first electronic device 100 displays twenty-four frames per second on the screen 110 to generate a visual image. f, wherein each of the twenty-four frames has a frame that is a predetermined frame fp, and the predetermined frame fp is used to display the connection information 120 of the first electronic device 100, for example, one of the first electronic devices 100. The Internet Protocol (IP) address and one of the first electronic devices 100 are connected to each other. The connection information 120 of the first electronic device 100 may be displayed in the form of a digital code, such as a one-dimensional barcode, a two-dimensional barcode, or a binary code string. The predetermined frame fp may be attached to the connection information 120 of the first electronic device 100 on a display block in the original frame, or the first electronic device 100 may additionally generate a connection including the first electronic device 100. The frame of line information 120 is replaced with one of the twenty-four frames. Since the first electronic device 100 displays only twenty-four frames per second on the screen 110, the predetermined frame fp includes the connection information 120 of the first electronic device 100, and the other twenty-three frames do not include the first The connection information 120 of the electronic device 100 is not visible to the user, and the user cannot detect that the visual image displayed on the screen 110 includes the connection information 120 of the first electronic device 100. Therefore, the connection of the first electronic device 100 Line information 120 is equivalent to being hidden in the visual image.

Please refer to FIG. 3 . FIG. 3 is a schematic diagram of a connection between the second electronic device 200 and the first electronic device 100 via the Internet according to the connection information included in the predetermined frame. As shown in FIG. 3 , the second electronic device 200 can capture the frame displayed on the screen 110 by the first electronic device 100 by using the camera module 210 . Since the frame capture frequency of the camera module 210 can generally be higher than the predetermined update frequency of the screen 110, the camera module 210 can easily capture the frame of the predetermined frame fp. When the second electronic device 200 receives the screen of the predetermined frame fp sent by the camera module 210, the second electronic device 200 can decode the digital code of the connection information 120 included in the predetermined frame fp to further obtain the A connection information 120 of an electronic device 100. After the second electronic device 200 obtains the connection information 120 of the first electronic device 100, the second electronic device 200 can be based on the connection information 120 of the first electronic device 100 (for example, the Internet protocol of the first electronic device 100) The connection between the address and the first electronic device 100 is established via the Internet and the first electronic device 100.

According to the above configuration, the present invention inserts the predetermined frame fp with the connection information 120 in the case where the original picture is not visually affected, so that the second electronic device 200 can easily obtain the first by the photography module 210. The connection information 120 of the electronic device 100 is further connected to the first electronic device 100 via the Internet. The user does not need to query the connection information of the electronic device in the console of the operating system and set the connection to establish a connection between the electronic devices.

In addition, in order to prevent other electronic devices from being arbitrarily connected to the first electronic device 100, the predetermined frame fp may further include connection authentication information of the first electronic device 100. For example, the predetermined frame fp may further include the first electronic device 100 generating one of the voucher information 122. When the second electronic device 200 is to be connected to the first electronic device 100, the second electronic device 200 must provide the first The voucher information 122 generated by the electronic device 100 is connected to the first electronic device 100. In this way, even if other electronic devices can know the Internet Protocol address of the first electronic device 100 and the connection number of the first electronic device 100, the other electronic devices cannot be arbitrarily connected to the first electronic device 100.
