Further, in the description of the examples, when it is considered that detailed description of well-known related structures or functions will cause a vague explanation of the present disclosure, such detailed description will be omitted.
Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Embodiments, however, may be embodied in various forms and are not limited to the examples described herein.
Fig. 1 is a block diagram illustrating a configuration of a shared screen processing apparatus according to an exemplary embodiment of the present disclosure. The shared screen processing apparatus as shown in fig. 1 may be implemented in various electronic terminals. Various electronic terminals include, but are not limited to, mobile phones, smart devices, tablet devices, televisions, wearable devices (such as smart watches), and the like.
Referring to fig. 1, a shared screen processing apparatus 100 according to an exemplary embodiment of the present disclosure includes an editing module 110, a composition module 120, and a transmission module 130. Here, the shared screen processing apparatus 100 may be implemented in a Central Processing Unit (CPU), a Graphic Processing Unit (GPU), or an Application Processor (AP) in the electronic terminal, but is not limited thereto.
The editing module 110 may extract a User Interface (UI) layer corresponding to a screen to be shared and perform a special effect process on the UI layer. Specifically, the editing module 110 may display the extracted UI layer and provide a special effects menu including at least one special effect on the extracted UI layer. The effects included in the effects menu may include, but are not limited to, mosaic, graffiti, stickers, cuts, zooms, text, animations, and the like. When a user of the electronic terminal selects a special effect included in the special effect menu and performs an operation on the extracted UI layer using the selected special effect (e.g., without limitation, adding a mosaic, a sticker, text, an animation, etc. on the extracted UI layer, cropping the extracted UI layer, etc., and/or performing scaling on all or part of the extracted UI layer, etc.), the editing module 110 may perform a special effect process on the extracted UI layer (i.e., adding a mosaic, a sticker, text, an animation, cropping, performing scaling, etc., as described above) in response to the user's selection of the special effect included in the special effect menu and the operation performed using the selected special effect.
The composition module 120 may combine the UI layer on which the special effect processing is performed with the screen to be shared to generate a shared screen. In the operation of generating the sharing screen, the composition module 120 may identify the content displayed by the screen to be shared, and then compose the user interface layer on which the special effect process is performed with the screen to be shared based on the identification result. Specifically, when the recognition result indicates that the screen to be shared displays picture content, the composition module 120 may combine the portion of the UI layer on which the special effect process is performed to the picture content. When the recognition result indicates that the screen to be shared displays video content, the composition module 120 may compose a portion of the user interface layer on which the special effect process is performed to the video content, and cancel the performed special effect process as the portion on which the special effect process is performed disappears from the video content. For example, when a mosaic special effect is added to a specific object appearing in video content, the added mosaic special effect is also cancelled as the specific object disappears from the video content (e.g., the scene of the video content changes so that the specific object no longer appears in the video scene). Further, when a portion on which the special effect processing is performed reappears in the video content after disappearing from the video content, the composition module 120 may restore the special effect processing performed on the portion. For example, when a specific object to which a mosaic special effect is added reappears in the video content as time passes after disappearing from the video content, the mosaic special effect will be restored to the specific object.
The transmitting module 130 may perform mobile screen projection on the generated shared screen. In particular, the transmitting module 130 may perform mobile screen projection on the generated sharing screen to share the generated sharing screen to the mobile electronic terminal or the stationary electronic terminal. For example, a mobile electronic terminal may include a mobile phone, a smart phone, a tablet device, etc., and a stationary electronic terminal may include a set-top box, a television, a projector, etc.
As described above, in the shared screen processing apparatus 100 according to the exemplary embodiment of the present disclosure, by applying a special effect to the shared screen content, it is possible to effectively block content that is not desired to be shared, thereby improving privacy. Further, in the shared screen processing apparatus 100 according to the exemplary embodiment of the present disclosure, by applying a special effect to the shared screen content, and cropping and/or scaling the screen content, the visibility of the screen content can be improved. Further, in the shared screen processing apparatus 100 according to the exemplary embodiment of the present disclosure, by applying a special effect to the shared screen content, inserting graffiti, stickers, characters, animation, and the like, the operability of the screen content can be improved, and the user experience can be improved.

Referring to fig. 2, according to the shared screen processing method, in step S201, a User Interface (UI) layer corresponding to a screen to be shared is extracted, and a special effect process is performed on the UI layer. Specifically, in step S201, the extracted UI layer may be displayed and a special effects menu including at least one special effect may be provided. Further, a special effect process may be performed on the extracted UI layer in response to a user's selection of a special effect included in the special effect menu and an operation performed using the selected special effect. As described above, the effects included in the effects menu may include, but are not limited to, mosaics, graffiti, stickers, cuts, zooms, text, animations, and the like. The special effect processing performed on the extracted UI layer may include, but is not limited to: adding mosaic, doodle, characters and animation on the selected UI layer; cutting the extracted UI layer; and performing scaling on all or part of the extracted UI layer.
In step S202, the UI layer on which the special effect processing is performed may be synthesized with the screen to be shared to generate a shared screen. Specifically, in step S202, the content displayed on the screen to be shared can be identified, and the UI layer on which the special effect processing is performed is synthesized with the screen to be shared based on the identification result. And when the identification result indicates that the screen to be shared displays the picture content, synthesizing the part of the UI layer, which is subjected to the special effect processing, into the picture content. When the recognition result indicates that the screen to be shared displays video content, a portion of the UI layer on which the special effect processing is performed is composited to the video content, and the performed special effect processing is cancelled as the portion on which the special effect processing is performed disappears from the video content. Further, when a portion on which the special effect processing is performed appears again in the video content after disappearing from the video content, the special effect processing performed on the portion is resumed.
In step S203, a mobile screen projection may be performed on the generated shared screen. In particular, mobile screen projection may be performed on the generated sharing screen to share the generated sharing screen to the mobile electronic terminal or the stationary electronic terminal.
As described above, in the shared screen processing method according to the exemplary embodiment of the present disclosure, by applying a special effect to the shared screen content, it is possible to effectively block content that is not desired to be shared, thereby improving privacy. Further, according to the shared screen processing method of the exemplary embodiment of the present disclosure, visibility of screen contents can be improved by applying a special effect to the shared screen contents, and cropping and/or scaling the screen contents.
