Accordingly, the electronic devices 100 and 200 respectively completely cover the original shared background image with the newly captured image as the main sharing. The background of the picture.

In the above embodiment, if the electronic device 100 can obtain additional information (eg, a web address) related to the first level of input content from the local end and/or the remote database, the electronic device 100 inputs the content of the first level. The representative information and the additional information are transmitted to the electronic device 200. The electronic device 200 can utilize the additional information for various subsequent processing (eg, opening related web pages).

It should be particularly noted that in the above embodiment, the user of the electronic device 100 uses the tool string 180 for input as an example, but when the user of the electronic device 200 inputs using the tool column 280, The first level of input content is also displayed on the electronic device 100 in real time. That is to say, the representative information of the first level input content is transmitted by the electronic device input by using the toolbar to other electronic devices at the main sharing level through the network, so that all the electronic devices at the main sharing level can display the same instant. The main share screen.

In another embodiment of the present invention, it is assumed that the electronic device 100 selects the electronic devices 200 and 300 to enter the primary sharing level of the sharing mode. Then, if the electronic device 300 wants to establish a sub-share group with the electronic device 100, after the electronic device 100 accepts the selection of the electronic device 300, the electronic device 100 and the electronic device 300 will switch from the main sharing level of the sharing mode to the sub-sharing level. . Before performing the above switching operation, the electronic device 100 and the electronic device 300 store the latest main sharing screen in its storage unit, and the latest main sharing screen includes the latest background and all the first level input contents before the switching.

After the electronic devices 100 and 300 are switched to the sub-sharing level, the electronic device Users of 100 and 300 can make input using a toolbar displayed on their child sharing screen to generate a second level of input content. The method for generating the second level of input content by using the toolbar is similar to the method for generating the first level of input content by using the toolbar, and displaying the second level of input content on the sub-share screen is also displayed first on the main sharing screen. The way of inputting content at the level is similar, so it will not be described here. Since the second level input content is only displayed in the sub sharing screen, the electronic device 200 not added to the sub sharing level cannot know the second level input content. In other words, the electronic devices 100 and 300 can perform instant sharing privately with each other.

In the above embodiment, the electronic devices 100 and 300 can switch back and forth between the primary sharing level and the child sharing level. As shown in FIG. 8, hierarchical switching options 810 and 820 are displayed on the sub-sharing screen 800 displayed by the electronic device 100 at the sub-sharing level, corresponding to the primary sharing level and the sub-sharing level, respectively. When the touch screen 110 of the electronic device 100 detects the second specific gesture (for example, the click gesture applied to the hierarchical switching option 810), the processing unit 140 of the electronic device 100 stores the latest child sharing screen 800 to the electronic device. The storage unit 130 of the 100 further switches the electronic device 100 from the sub-sharing level to the main sharing level, and displays the main sharing screen previously stored in the storage unit 130 on the touch screen 110 to replace the sub-sharing screen 800.

After the electronic device 100 switches to the primary sharing level, if the touch screen 110 of the electronic device 100 detects the second specific gesture (eg, a click gesture) applied to the hierarchical switching option 820, the processing unit of the electronic device 100 The first main sharing screen is stored in the storage unit 130, and then the electronic device 100 is switched from the main sharing level to the sub-sharing level, and the touch screen 110 is displayed in the storage unit. 130 child sharing screen to replace the main sharing screen.

Although the above embodiment is described by taking the electronic device 100 as an example, the electronic device 300 can also switch back and forth between the primary sharing level and the sub-sharing level when the second specific gesture is detected.
