Single Control Point for Boundary Line Positioning in Preview Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control apparatuses for MFPs require significant time and effort to adjust boundary lines in preview images, as they necessitate the operation of multiple control points to change the positions of straight lines used as boundary lines.
Innovation Solution
A display control apparatus and method that allows users to easily determine boundary lines in a preview image by using a single control point to position vertical and horizontal boundary lines, dividing the preview image into split areas comprising parts of the initial and processed images, enabling intuitive operation and comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple control points are used to determine boundary line positions in a preview image, then the precision of boundary line positioning is improved, but the ease of operation deteriorates due to the need to operate multiple control points
Solution Approach 1:
The patent merges multiple control points into a single control point that simultaneously controls multiple boundary lines. Instead of requiring separate control points for each boundary line, one control point is used to determine the positions of multiple boundary lines, thereby maintaining positioning precision while significantly improving ease of operation.
Solution Approach 2:
The single control point serves multiple functions by controlling multiple boundary lines simultaneously. This multi-functional control point replaces what would traditionally require multiple specialized control points, achieving both boundary line positioning precision and operational simplicity through one universal control element.
2Adaptability or versatility
If multiple control points are operated to change boundary line positions, then the adaptability of boundary line positioning is improved, but the time required for operation increases
Solution Approach 1:
By combining multiple control functions into a single control point, the system maintains the adaptability to position multiple boundary lines while reducing the time required for operation. The user interacts with one control point instead of multiple, significantly reducing operation time while preserving positioning flexibility.
Solution Approach 2:
The system is pre-configured with the relationship between the single control point and multiple boundary lines, so that when the user moves the control point, all boundary lines are automatically adjusted according to the predetermined relationship. This preliminary setup eliminates the need for sequential adjustment of each boundary line, reducing operation time while maintaining adaptability.

AI summary
A display control apparatus which enables a user to easily determine positions of boundary lines in a preview image. A first image is generated based on an initial image or a processing result of first image processing performed on the initial image, and a second image is generated based on a processing result of second image processing performed on the initial image. Display of the preview image is controlled based on the first image and the second image. An operation performed by a user on a control point for determining a position of at least one boundary line in the preview image is received. In a display process for the preview image, at least a part of the first image and at least a part of the second image are displayed based on the boundary line the position of which is determined by the control point.
