Lock Screen Depth Image Layout Across Screen Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display effect of depth-of-field images on lock screens deteriorates when the screen orientation changes, such as from portrait to landscape, due to shifts in the relative position between the main image and the system time indicator, affecting the aesthetic quality.
Innovation Solution
The method involves displaying a first lock screen image with a main image positioned relative to the system time indicator, and upon rotation, replacing it with a second image maintaining the same relative position, ensuring consistent display aesthetics by aligning the main image's position relative to the system time indicator before and after rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the lock screen image is displayed using a standard depth-of-field image without rotation-specific processing, then the image can be displayed quickly with simple processing, but the display effect deteriorates when screen rotation occurs due to position shifts
Solution Approach 1:
The patent applies preliminary action by pre-processing the original image into multiple rotation-specific images (first image for portrait mode, second image for landscape mode) before the rotation occurs. When screen rotation is detected, the system simply switches between pre-prepared images rather than performing complex real-time processing, thus maintaining high display effect precision while avoiding complex runtime processing.
Solution Approach 2:
The patent implements dynamics by making the displayed image dynamic based on screen rotation state. The system switches between different pre-processed images according to the current rotation state, ensuring that the main image's relative position to the system time indicator remains consistent across different orientations, thereby resolving the display effect deterioration issue.
2Stability of the object's composition
If the system processes and stores multiple rotation-specific images, then the display aesthetics are maintained across rotations, but the storage requirements and processing time increase
Solution Approach 1:
The system performs image processing in advance during setup or idle time, creating rotation-specific images before they are needed. This preliminary processing ensures display composition stability is maintained during actual use without causing time loss during rotation events, as the processing work is already completed beforehand.
Solution Approach 2:
The patent uses copying by creating multiple versions (copies) of the original image tailored for different rotation states. Instead of performing complex transformations during rotation, the system directly uses pre-copied images that are already optimized for specific orientations, thus maintaining composition stability while minimizing processing time during actual rotation events.
3Manufacturing precision
If the main image position is adjusted dynamically after rotation, then the relative position can be corrected, but the processing complexity and time increase during rotation events
Solution Approach 1:
The patent applies preliminary action by pre-calculating and embedding the correct positioning information into rotation-specific images during the initial processing stage. When rotation occurs, the system simply switches to the appropriate pre-positioned image rather than performing complex real-time position adjustments, thus maintaining position precision while keeping the rotation operation simple and fast.

AI summary
This application discloses a method for displaying a lock screen image, an electronic device, and a readable storage medium, and belongs to the field of terminal technologies. The method is applied to the electronic device, and includes: The electronic device displays a first lock screen in response to a screen-on operation, where the first lock screen includes: a first image, a system time indicator displayed on the first image, and a main image partially blocking the system time indicator; and the electronic device displays a second lock screen in response to a rotation operation on the electronic device, where the second lock screen includes: a second image, the system time indicator displayed on the second image, and the main image partially blocking the system time indicator. Because a relative position between the main image and the system time indicator does not change before and after the electronic device is rotated, display effect of a depth-of-field image is ensured before and after a display screen is rotated, and display aesthetics of the depth-of-field image is improved.
