Image Division with Automatic Rotation for Touch Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image division technologies on touch panels can only set one division line and do not allow for the easy setting of multiple sub-screens with intersecting division lines at predetermined angles, limiting user-friendliness and flexibility.
Innovation Solution
An image division method and apparatus that enables users to set multiple division lines that intersect at predetermined angles, such as 90 degrees, by rotating the image and allowing continuous slide operations to create orthogonal or parallel lines, simplifying the process and reducing the number of user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only one division line is set, then the operation is simple, but the ability to divide screen into three or more sub-screens is not provided
Solution Approach 1:
The system automatically rotates the image by 90 degrees after each division line is set, preparing the image in advance for the next division line to be set at the correct orientation. This preliminary rotation action enables users to set multiple division lines without manually adjusting the image orientation each time.
Solution Approach 2:
The system dynamically adjusts the image rotation angle based on the number of division lines set. After the first division line, the image rotates 90 degrees; after the second division line, it rotates another 90 degrees, and so on. This dynamic adaptation allows the system to handle multiple division lines automatically.
2Adaptability or versatility
If multiple division lines are set manually, then the screen can be divided into multiple sub-screens, but the number of user operations increases
Solution Approach 1:
The system performs the image rotation action automatically after each division line is set, without requiring additional user input. The system serves itself by detecting when a division line is set and automatically rotating the image to the next required angle, eliminating the need for manual rotation operations.
Solution Approach 2:
The system provides visual feedback by displaying the rotated image after each division line is set. This feedback mechanism confirms to the user that the rotation has occurred and the image is ready for the next division line, reducing the need for additional verification operations.
3Manufacturing precision
If the image is rotated to set division lines at predetermined angles, then orthogonal or parallel lines can be created, but the image may not be displayed fully on the screen
Solution Approach 1:
The system changes the rotation angle parameter in increments of 90 degrees based on the number of division lines set. This parameter change ensures that division lines are created at precise predetermined angles (0°, 90°, 180°, 270°) while maintaining proper image orientation for complete display.

AI summary
An image may be divided into multiple portions or sub-images using division lines. To facilitate this process, the division lines may be drawn with user input in a single direction. The image may then be rotated to allow a user to draw lines extending in other directions using the same user input direction. In some instances, rotation may be automatically performed upon drawing of a division line, deletion of a sub-image, receiving a specified user command or type of user input and the like. Additionally or alternatively, upon rotating the image a first time in one direction, a subsequent rotation of the image may be performed in an opposite direction. The first rotation and the subsequent rotation may be of the same rotation amount. If a sub-image is deleted, a remaining sub-image or sub-images may be resized or otherwise modified to fit within the display.
