Display Area Scrolling With Fixed-Image Replacement for Smooth Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in maintaining smooth user interaction when display content is moved, particularly when high processing load frames are involved, leading to potential malfunctions and reduced rendering performance.
Innovation Solution
An information processing apparatus and method that detects user inputs for moving display areas, identifies predetermined content, and replaces it with a fixed image during movement to reduce processing load, ensuring smooth animation display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the CPU processes display content switching for each frame to follow user operations, then the image can follow user operations smoothly, but the processing load increases and may cause system malfunction
Solution Approach 1:
The patent changes the parameter of image processing by switching from dynamic frame-by-frame processing to static image display during scrolling operations. When the display area moves, the system identifies predetermined content and replaces it with a fixed image, changing the processing mode from active rendering to static display, thereby reducing CPU load while maintaining visual continuity
Solution Approach 2:
The patent applies preliminary action by pre-identifying predetermined content that requires fixed image replacement before the scrolling operation completes. The system determines in advance which content should be replaced with fixed images, preparing the static display state beforehand to ensure smooth transitions and avoid processing delays during actual scrolling
2Productivity
If frames with low display priority continue to be displayed without switching to reduce CPU load, then processing load decreases, but the image cannot follow user operations
Solution Approach 1:
The patent applies local quality by differentiating the processing approach for different content types. Instead of uniformly processing all frames, the system identifies predetermined content locally and applies fixed image replacement specifically to those regions during scrolling, while other content can continue normal frame switching. This localized treatment reduces overall processing load while maintaining user interaction responsiveness for important content
3Reliability
If the CPU load threshold is set low to prevent system malfunction, then system stability improves, but rendering performance and user experience deteriorate
Solution Approach 1:
The patent applies dynamics by making the display processing mode adaptive rather than static. The system dynamically switches between normal frame-by-frame rendering and fixed image display based on real-time conditions such as whether the display area is moving, what content is being displayed, and current CPU load. This dynamic adjustment allows the system to maintain high rendering quality during static displays while ensuring stability during scrolling operations

AI summary
Provided is a controller configured to execute: detecting an input for moving a display area within a screen, the display area being an area in which an image corresponding to content is displayed; identifying, in response to detection of the input, content corresponding to the image displayed in the display area within the screen; and replacing, in response to the content thus identified being predetermined content, an image corresponding to the predetermined content while moving the display area within the screen, with a predetermined fixed image.
