Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital camera systems face inefficiencies in retrieving image data from storage media, as users struggle to quickly locate specific images among large collections, with existing methods either displaying images sequentially or using multi-image displays that do not effectively facilitate rapid selection.
Innovation Solution
An image display apparatus and method that includes an image-processing unit, an image display unit, and a display control unit, which generates and displays data representing images in a multi-image format, allowing users to jump to images by a predetermined number, displaying intervening images for a varying period to facilitate efficient retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If images are displayed sequentially one after another, then the display control is simple, but the time required to retrieve specific images increases significantly
Solution Approach 1:
The patent segments the image display into multiple simultaneous display positions (e.g., 2x2 grid showing 4 images at once). By dividing the sequential stream into parallel segments, users can see multiple images concurrently, reducing retrieval time while maintaining manageable display complexity through structured arrangement.
Solution Approach 2:
The patent transitions from one-dimensional sequential display to two-dimensional simultaneous display by arranging multiple images in a grid format on the display screen. This dimensional change allows users to perceive multiple images at once, dramatically reducing the time needed to locate specific images while the control mechanism remains relatively simple.
2Productivity
If multi-image display is used to show multiple images simultaneously, then image retrieval efficiency improves, but the display area required increases
Solution Approach 1:
The patent divides the display area into segmented regions, each showing a specific image from the collection. By organizing images in a grid pattern (e.g., 2x2), the system maximizes the use of available display area, showing multiple images simultaneously without requiring excessive total area. The segmentation allows efficient use of space while maintaining high retrieval efficiency.
Solution Approach 2:
The patent displays a partial set of images (e.g., 4 out of many total images) simultaneously in a structured grid. This partial action approach shows enough images to enable efficient retrieval without filling the entire display area, optimizing the balance between retrieval efficiency and display area utilization. The system displays sufficient images to be useful while leaving room for navigation controls.
3Device complexity
If images are displayed at fixed speed, then the playback control is simple, but the user cannot quickly locate specific images in large collections
Solution Approach 1:
The patent implements dynamic playback speed adjustment based on user needs. The system can operate in normal sequential mode for simple browsing, but also provides accelerated modes where images are displayed faster or multiple images are shown simultaneously. This dynamic adaptation allows users to quickly locate specific images in large collections by increasing the display speed or changing the display pattern, while the control mechanism remains relatively simple through dedicated jump buttons.
Solution Approach 2:
The patent enables users to skip through images by displaying multiple images simultaneously or advancing through images at accelerated speed. The jump-instructing unit allows users to rush through intermediate images to reach target images faster, particularly useful when searching for specific images in large collections. This skipping mechanism dramatically improves image location speed while adding minimal complexity to the control system.
Data Source
AI summary
An image display apparatus has an image-processing unit, an image display unit, and a jump-instructing unit. The image-processing unit generates data representing images having frame numbers. The image display unit displays the images represented by the data. The jump-instructing unit generates an instruction to cause the image display unit to display an image whose serial number differs, by a predetermined number, from that of the image being displayed by the image display unit. In response to the instruction, the image-processing unit generates data representing a multi-image consisting of images intervening between the image being displayed and the image whose serial number differs by the predetermined number. The image display unit first displays the multi-image and then the image whose serial number differs by the predetermined number.
