However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concept of the example embodiments to those skilled in the art.

[0050] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure.

In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present disclosure.

[0051] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0052] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0053] Figure 1 A schematic diagram of an exemplary system architecture 100 is shown to which the drawing method according to the embodiments of the present disclosure can be applied.

[0054] like Figure 1As shown, the system architecture 100 may include one or more of terminals 101, 102, 103, a network 104, and a server 105. The network 104 is a medium for providing a communication link between the terminals 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0055] It should be understood that Figure 1 The number of terminals, networks and servers in the embodiment is only for illustration. Any number of terminals, networks and servers may be provided as required. For example, the server 105 may be a server cluster composed of multiple servers.

[0056] Staff or users can use terminals 101, 102, 103 to interact with server 105 through network 104 to receive or send messages, etc. Terminals 101, 102, 103 can be various electronic devices with display screens, including but not limited to smartphones, tablet computers, portable and desktop computers, digital movie projectors, etc.

[0057] The server 105 may be a server that provides various services. For example, when a staff member or a user sends various operation instructions in the drawing process to the server 105 through the terminal 103 (or the terminal 101 or 102), the server 105 may obtain a background image, wherein the background image has a pattern; receive the user's input on the background image; dynamically display the user's input on the background image; wherein the user's input on the background image is a new pattern added by the user on the background image. The server 105 may display the drawing result on the terminal 103 or other terminals, and then the staff member or other personnel (for example, the user) may view the drawing result based on the content displayed on the terminal.

[0058] For another example, the terminal 103 (or the terminal 101 or 102) may be a smart TV, a VR (Virtual Reality) / AR (Augmented Reality) helmet display, or a mobile terminal such as a smart phone or tablet computer on which a navigation, online car-hailing, instant messaging, or video application (application, APP) is installed. The staff or user may operate through the smart TV, VR / AR helmet display, or the navigation, online car-hailing, instant messaging, or video APP, and the server 105 may perform corresponding operations according to the instructions of the terminal 103. The server 105 may return the drawing result to the or other smart TV, VR / AR helmet display, or the navigation, online car-hailing, instant messaging, or video APP, and then display the drawing result through the smart TV, VR / AR helmet display, or the navigation, online car-hailing, instant messaging, or video APP.

[0075] In step S330, the user's input on the background image is dynamically displayed.

[0076] In this step, the terminal or server dynamically displays the user's input on the background image. In one embodiment, dynamically displaying the user's input on the background image includes: displaying the user's input on the background image with dynamic ant lines or dynamic brightness changes. In one embodiment, when the user's input is a straight line or a curve, the straight line or curve input by the user on the background image is dynamically displayed; when the user's input is a closed figure, the boundary line of the closed figure input by the user on the background image is dynamically displayed.

[0078] When the user input is a closed figure, the perimeter or area of ​​the closed figure input by the user is displayed on the background image.

[0079] In one embodiment, when the user clicks on other areas outside the new pattern input by the user on the background image, the new pattern input by the user on the background image is no longer dynamically displayed;

[0080] When the user clicks on the new pattern input by the user on the background image, the new pattern input by the user on the background image is dynamically displayed.

[0081] In one embodiment, when the new pattern input by the user on the background image is dynamically displayed, the user is allowed to edit the new pattern input by the user on the background image.
