Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic wallpapers on electronic devices are limited in user customization, lack interactivity, and fail to provide spatial effects during interface switching, reducing user engagement.
Innovation Solution
A method that allows users to select and customize images for multiple graphic layers, which are processed into a target video using a virtual camera to create dynamic depth effects during interface switching, enhancing interactivity and interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static wallpaper is displayed, then the device complexity is low, but the interactivity and user engagement are reduced
Solution Approach 1:
The wallpaper is divided into multiple graphic layers, each containing different image elements that can be independently selected and customized by users. This segmentation allows complex interactive functionality while maintaining manageable system structure through modular layer design.
Solution Approach 2:
The wallpaper system transitions from static to dynamic through virtual camera photographing that captures scene images with depth of field effects. The dynamic wallpaper is generated by processing multiple graphic layers through virtual photographing operations, creating animated transitions during interface switching.
2Adaptability or versatility
If a dynamic wallpaper is used, then user engagement improves, but the range of selectable wallpapers is limited
Solution Approach 1:
The virtual camera module serves multiple functions: it photographs scene images, generates depth of field effects, creates dynamic wallpaper animations, and processes transitions between different interfaces. This multi-functionality enables extensive customization without proportionally increasing system complexity.
Solution Approach 2:
The system uses virtual camera copying to create scene images from multiple graphic layers. Instead of requiring separate physical photographs for each wallpaper, the virtual camera copies and processes the layered graphic elements to generate dynamic wallpaper effects, reducing the need for extensive pre-produced wallpaper assets.
3Illumination intensity
If multiple graphic layers are processed with virtual camera photographing, then spatial effects and depth of field are achieved, but processing power consumption increases
Solution Approach 1:
Scene images are pre-photographed by the virtual camera for each preset interface before actual interface switching occurs. These pre-generated scene images are stored and readily available for quick retrieval during interface transitions, avoiding real-time processing of multiple graphic layers when the interface switches, thus reducing instantaneous processing power consumption.
4Manufacturing precision
If scene images are obtained by virtual camera with different photographing angles, then depth of field variation is achieved, but the processing time increases
Solution Approach 1:
Scene images corresponding to different preset interfaces are photographed in advance by the virtual camera with appropriate depth of field settings. During interface switching, the system directly retrieves and displays the pre-prepared scene images, eliminating the need for real-time photographing and processing, thus maintaining high depth of field accuracy while minimizing interface switching time.

AI summary
This application provides a wallpaper display method, an electronic device, and a storage medium, and relates to the field of terminals. The method in this application includes: obtaining, in response to a first select operation of a user, an image respectively corresponding to each graphic layer from a gallery, where each graphic layer corresponds to a different image; adjusting a position and a size of the image respectively corresponding to each graphic layer; obtaining, in response to an interface switching operation, a target video of changing from a scene image of a current preset interface to a scene image of a next preset interface, where a scene image of each preset interface is obtained by a virtual camera by photographing a scene including all graphic layers based on a photographing angle corresponding to the preset interface; and using the target video as a wallpaper of the electronic device, and displaying the wallpaper. By using the method in this application, the electronic device can edit the wallpaper based on an image selected by the user, thereby improving the interactivity between the electronic device and the user.
