Image Processing Apparatus Scroll Prediction Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying multiple video contents on a screen suffer from delays due to decoding processing only starting after the next content is determined, and they fail to predict and prepare content for display based on scroll display conditions and screen movement.
Innovation Solution
An image processing apparatus predicts content data likely to be displayed next according to scroll display control conditions and decodes this data before it enters the display area, using a prediction unit and decoding unit within a display control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If video content is decoded only after it is determined to be displayed next, then decoding resources are used efficiently, but display delay occurs
Solution Approach 1:
The system performs preliminary decoding of video content before it is actually needed for display by predicting future display requirements based on scroll direction, speed, and user interaction patterns. This allows the decoded content to be ready in the buffer when needed, eliminating display delay while maintaining efficient resource usage through intelligent prediction rather than continuous pre-decoding of all content.
2Adaptability or versatility
If multiple video contents are displayed simultaneously with scroll function, then user experience is improved, but it becomes difficult to predict next content based on file management structure
Solution Approach 1:
The system continuously monitors actual scroll behavior, user selection patterns, and display timing to refine its prediction algorithms. By comparing predicted next content with actual user choices and adjusting prediction weights accordingly, the system maintains high prediction accuracy even when multiple video contents are displayed simultaneously in various scroll configurations.
3Loss of time
If content data is decoded in advance, then display delay is reduced, but memory resources are consumed
Solution Approach 1:
Instead of decoding all possible next content or using complex prediction, the system decodes only a limited number of candidate contents (e.g., next 1-3 items) based on simple scroll direction and speed detection. This partial pre-decoding approach reduces memory consumption significantly while still providing sufficient buffer to eliminate noticeable display delay under normal scrolling conditions.

AI summary
An image processing apparatus includes a display control unit configured to scroll a plurality of pieces of content data, a prediction unit configured to predict which content data among the plurality of pieces of content data moves from a hidden area to a display area according to a scroll display control condition controlled by the display control unit, and a decoding unit configured to decode the content data predicted by the prediction unit before the predicted content data moves to the display area.
