Touch Display Control Maintaining Enlargement During Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems fail to efficiently switch between enlarged images while maintaining the enlargement factor and position, either losing the enlargement factor when switching images or requiring non-touch operations to maintain it.
Innovation Solution
A display control apparatus with a detection unit for touch operations, a display control unit to manage image portions, and a control unit that maintains the enlargement factor and position during image switching by detecting specific touch movements within predetermined regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image switching is performed using conventional methods, then the switching operation can be completed, but the enlargement factor and enlarged position cannot be maintained during the switching process
Solution Approach 1:
The system performs preliminary actions by detecting touch operations and pre-processing the image switching while maintaining enlargement parameters. The control unit prepares the next image for display while preserving the current enlargement factor and position, so that when switching occurs, the parameters are already set and maintained throughout the transition.
Solution Approach 2:
The system creates a copy of the enlargement state (enlargement factor and position) and applies it to the next image being displayed. When switching from the first image to the second image, the enlargement parameters are copied from the current display state and maintained for the new image, ensuring consistency across image transitions.
2Ease of operation
If touch operations are used for image switching, then operationality is improved, but the enlargement factor is lost during switching
Solution Approach 1:
The system implements feedback by continuously monitoring touch operations and adjusting the image display accordingly. When a touch operation detects a swipe or flick gesture, the system provides feedback by maintaining the enlargement factor and position while switching images, ensuring that the user's intent is preserved and the enlargement information is not lost during the transition.
Solution Approach 2:
The control unit performs preliminary processing by preparing the next image with the same enlargement parameters before the actual switch occurs. This preliminary action ensures that when the touch operation completes, the enlargement factor information is already preserved and applied to the new image, preventing any loss of enlargement data during switching.
3Productivity
If conventional image switching is implemented, then simple switching is achieved, but user operationality for maintaining detailed view is poor
Solution Approach 1:
The system applies dynamics by making the enlargement parameters adaptable and responsive to user gestures. Instead of fixed enlargement settings, the system dynamically maintains the enlargement factor and position based on the detected touch operation, allowing the display to adapt to user intent while preserving the detailed view during image transitions.
Solution Approach 2:
The touch operation system is designed to be universal by handling multiple functions: it detects swipes for image switching, maintains enlargement factors, and preserves positioned views all through a single gesture interface. This multi-functionality allows the same touch operation to simultaneously perform switching while maintaining detailed view capabilities, improving both productivity and ease of operation.

AI summary
A display control apparatus includes: a detection unit to detect touch operations; a display control unit to effect control such that a portion of an image is displayed on a display unit rather than an entire image; a portion changing unit to change a displayed portion of the image when a portion of the image is being displayed, according to a predetermined touch operation including moving of a touch position having been performed from outside of a predetermined region; and a control unit to effect control such that, when a portion of the image is being displayed, the displayed image is switched to a different image and a display portion of the different image is displayed on the display unit based on the display portion of the image before switching, according to the predetermined touch operation including moving of a touch position having been performed from outside the predetermined region.
