Display Control Apparatus Prioritizing Image Processing for Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital devices face delays in displaying multiple images simultaneously due to long processing times for image data preparation, especially when scrolling at high speeds, leading to incomplete display and user frustration.
Innovation Solution
A display control apparatus prioritizes the processing of images based on their position relative to the scrolling direction, prioritizing images further downstream in the scrolling direction to ensure timely display and prevent delays, even at high scrolling speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional sequential processing is used to display multiple images simultaneously, then all images can be displayed on the screen, but the processing time becomes excessively long causing display delays
Solution Approach 1:
The patent applies preliminary action by pre-processing images before they are needed for display. Specifically, images are decoded, resized, and converted to display format in advance while the user is scrolling or before they enter the display area, so that when they are needed they are already ready for immediate display without causing delays
Solution Approach 2:
The patent segments the image processing workflow into distinct stages: decoding, resizing, format conversion, and display. By dividing the processing into segments and using multiple processing units that can work in parallel on different segments simultaneously, the overall processing time is reduced while maintaining the ability to display multiple images
2Speed
If scrolling speed is increased to improve user experience, then users can browse images faster, but display preparation time becomes insufficient causing images to be delayed or not displayed
Solution Approach 1:
The system performs preliminary processing of images that are about to enter the display area or have just entered, preparing them in advance so that even at high scrolling speeds, the images are ready for immediate display without causing delays or missing displays
Solution Approach 2:
The patent maintains continuous processing by always having images being prepared in advance while other images are being displayed. The processing pipeline operates continuously without idle periods, ensuring that as long as the user scrolls, there are always images ready to be displayed, maintaining reliability at high speeds
3Ease of operation
If images positioned closely to previously displayed images are prioritized for processing, then users can find previously browsed images quickly, but newly displayed images during scrolling experience delays
Solution Approach 1:
The patent applies local quality by assigning different processing priorities to different spatial positions of images relative to the display area. Images at the leading edge (about to enter display) receive higher priority processing, while images already in or near the display area can use lower priority processing, optimizing both retrieval ease and display timing

AI summary
An apparatus capable of displaying a plurality of images while a screen is scrolled, including a processing unit configured to process an image to be displayed on a display unit, a display control unit configured to control the display unit to display a plurality of images processed by the processing unit, a scroll control unit configured to set another plurality of images as display targets to be displayed on the display unit by scrolling the displayed plurality of images, and a control unit configured to control the processing unit to process the plurality of images as the display targets such as to prioritize the processing for an image disposed on an upstream side over an image disposed on a downstream side in a moving direction of scrolled images.
