Display Animation Index Mapping for Natural Screen Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interface devices experience unnatural animation rendering before and after screen transitions when screen information of the transition source and destination screens are different.
Innovation Solution
Assigning first and second indices to still images such that feature points with periodic movements correspond between them, allowing continuous playback of these images to maintain animation continuity during screen transitions by selecting the appropriate index for the pre-transition image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If screen information of the transition source screen is not saved and the transition source screen and the transition destination screen are different, then processing load is reduced, but the rendering of the animation becomes unnatural before and after the screen transition
Solution Approach 1:
The system performs preliminary actions by saving essential screen information during the transition process. Specifically, it saves the display mode and animation playback progress of the transition source screen before switching to the destination screen. This preliminary saving enables the system to restore and continue animation playback naturally after the transition, avoiding the need to re-render animations from scratch while maintaining visual continuity and naturalness.
2Reliability
If screen information is saved during transition, then animation continuity is maintained, but processing load and memory usage increase
Solution Approach 1:
The system extracts and saves only the essential screen information required for maintaining animation continuity, rather than saving the entire screen data. Specifically, it extracts and stores the display mode (first display mode or second display mode) and the animation playback progress. This selective extraction approach maintains animation continuity while significantly reducing memory usage compared to saving complete screen information.
3Adaptability or versatility
If the transition source screen and transition destination screen are different, then screen functionality is optimized, but animation rendering becomes discontinuous
Solution Approach 1:
The system implements a universal animation management mechanism that works across different screen types and transition scenarios. By saving the display mode and animation playback progress in a standardized manner, the system can seamlessly handle transitions between various screen configurations (first display mode, second display mode, etc.). This universal approach ensures animation continuity is maintained regardless of the specific screen types involved in the transition.

AI summary
In the display control device according to the present embodiment, a first index and a second index are assigned to a plurality of first still images and a plurality of second still images, respectively, such that the feature points having periodic movements correspond between the plurality of first still images and the plurality of second still images; a first animation included in a first display screen and a second animation included in a second display screen are displayed by means of continuous playback of the plurality of first still images and the plurality of second still images; when there is a transition from the first display screen to the second display screen, a pre-transition image, which is the first still image immediately before the screen transition, is displayed, the second index corresponding to the first index assigned to the pre-transition image is selected to play back the second still image.
