Image Display Device Priority Data Reading for Fast Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices face challenges in keeping up with user-driven changes in displaying multiple images due to inefficient data reading and conversion processes, leading to waiting times and potential extra processing steps when priority orders change during these processes.
Innovation Solution
An image display device that prioritizes data reading and conversion based on the likelihood of image selection, using a process target list to manage and update the order of operations, allowing for simultaneous or parallel processing of data reading and format conversion, and storing images in different formats for speed and quality prioritization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image data is read and converted in advance before user instruction, then display speed is improved, but the pre-display process cannot keep up with the speed of sequential image changes
Solution Approach 1:
The patent applies preliminary action by reading and converting image data in advance before the user issues a display target change instruction. Specifically, when a user views images in sequence, the system reads and converts the next image data (image N+1) before the user actually requests to switch to it. This pre-processing reduces the waiting time when the user does switch, as the data is already prepared in memory ready for immediate display.
Solution Approach 2:
The patent implements dynamics by making the pre-display process adaptive to user behavior. The system dynamically adjusts which images are pre-processed based on the actual display target change instructions issued by the user. If the user changes the display sequence or skips images, the pre-display process automatically updates its targets accordingly, ensuring that pre-processed data remains relevant and useful.
2Device complexity
If image data is read in a fixed order, then processing is simplified, but the reading order does not match the likelihood of becoming a display target
Solution Approach 1:
The system performs preliminary actions by reading image data in an optimized order that anticipates future display needs. Instead of simply reading images in sequential order (1, 2, 3, 4...), the system reads them in an order based on their likelihood of being displayed next, such as reading image 3 before image 2 if the user is more likely to navigate forward. This intelligent pre-loading reduces waiting time while maintaining manageable processing complexity.
3Speed
If a data format with smaller data size is used for conversion, then transfer speed is improved, but image quality deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the image data processing into two distinct segments or formats: a high-quality format that preserves maximum image quality, and a compressed format that reduces data size for faster transfer. The system can selectively use either format depending on the specific display situation, such as using the compressed format for quick previews and the high-quality format when the user requests full-quality display, thus balancing speed and quality requirements.
4Duration of action of stationary object
If pre-display process continues when target image changes during processing, then process continuity is maintained, but extra processing steps are executed
Solution Approach 1:
The patent implements feedback by continuously monitoring whether the pre-display processing is still relevant to the current display target. Before completing a pre-display conversion operation, the system checks if the target image has changed. If the target has changed, the system cancels or redirects the ongoing pre-display process to the new target, avoiding wasted processing on obsolete data. This feedback mechanism ensures process efficiency by eliminating extra processing steps while maintaining overall process continuity.
