Dynamic Image Feeding Control for Rapid Photo Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image search techniques, such as those described in Japanese Laid-open Patent Publication No. 2007-221721, fail to reliably and quickly locate a desired image due to limitations in display modes and operation methods.
Innovation Solution
A display control apparatus that switches between single and multi-image display modes based on user operation, using a rotary encoder or similar operation member, allowing for efficient image feeding and switching between modes when a predetermined number of images is reached, enabling quick and accurate image retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-image feeding is implemented to quickly search for images, then image search speed is improved, but image search reliability deteriorates
Solution Approach 1:
The patent implements dynamic switching between single-image feeding mode and multi-image feeding mode based on real-time detection of user operations. The system transitions from a static display mode to a dynamic adaptive mode that adjusts image feeding behavior according to user interaction patterns, allowing fast forward/search when needed while maintaining reliable single-image display when required
Solution Approach 2:
The patent changes the parameter of image feeding mode (single vs. multi-image) based on operation duration thresholds. When the operation button is pressed for a duration exceeding a predetermined threshold, the system switches to multi-image feeding mode for rapid search; otherwise, it maintains single-image feeding mode for reliable display, thus resolving the contradiction between speed and reliability
2Reliability
If single image feeding is used to display images one by one, then image search reliability is improved, but image search speed deteriorates
Solution Approach 1:
The system dynamically adapts its image feeding behavior based on user operation characteristics. By detecting the duration of button presses, it automatically switches between reliable single-image feeding and fast multi-image feeding modes, ensuring both reliability and speed are achieved in their respective appropriate contexts
Solution Approach 2:
The patent modifies the image feeding parameter (number of images displayed simultaneously) based on the operation duration parameter. This allows the system to provide reliable single-image feeding for normal operations while enabling rapid multi-image feeding when users perform prolonged operations, thus resolving the speed-reliability trade-off
3Adaptability or versatility
If multiple display modes are implemented to accommodate different search needs, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal control mechanism where a single operation button serves multiple functions: it can trigger single-image feeding, multi-image feeding, fast forward, and search operations. By making the operation member multi-functional, the system achieves high adaptability without proportionally increasing device complexity
Solution Approach 2:
The system achieves multiple display modes by changing operational parameters (image feeding speed, number of images displayed) rather than adding separate physical controls for each mode. This parameter-based approach to adaptability maintains relatively simple device architecture while providing versatile functionality

AI summary
A display control apparatus that enables to reliably and quickly search for a desired image. When a wheel is operated by a user by an amount less than a predetermined operation amount, image feeding is made in a first display mode where a plurality of images are displayed on an image display unit. When the wheel is operated by the user by an amount equal to or greater than the predetermined operation amount, image feeding is made in a second display mode where a larger number of images than in the first display mode are displayed on the image display unit in a smaller size than in the first display mode.
