Print Preview Image Layout Adjustment via Touch Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems require complex operations to change the layout of images on a print preview screen, involving multiple steps to select and designate edit content, which complicates the arrangement of images on a print paper.
Innovation Solution
A computer-readable medium with an image processing program that allows users to easily change the layout of images on a print preview screen using a touch panel, enabling intuitive operations such as rotating, magnifying, and reducing images, and switching between different layouts by designating the number of images per print paper, while maintaining the orientation of other images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the user selects a layout that arranges multiple images on one print paper, then the layout efficiency is improved, but the size of each individual image becomes small making it difficult to confirm details
Solution Approach 1:
The patent introduces a zoom function that adds a magnification dimension to the preview display. When multiple images are arranged on one print paper (improving layout efficiency), the user can zoom in on individual images to confirm details (recovering image detail visibility). This dimensional change in display magnification resolves the contradiction between efficient multi-image layout and individual image detail confirmation.
2Adaptability or versatility
If the user changes the layout by selecting layout buttons and designating edit content, then the layout can be changed, but the operation becomes complex
Solution Approach 1:
The patent extracts the layout change function from the complex multi-step process and implements it as a simple drag-and-drop operation. Instead of requiring users to select layout buttons and designate edit content through multiple steps, the invention allows users to directly drag images to desired positions on the print paper preview, achieving layout changes with a single intuitive gesture that reduces operation complexity while maintaining layout adaptability.
3Loss of information
If the user magnifies the preview image to confirm individual images, then image detail visibility is improved, but the overall layout confirmation becomes difficult
Solution Approach 1:
The patent implements dynamic zoom functionality that allows the preview image magnification level to change freely based on user interaction. Users can zoom in to confirm individual image details or zoom out to view the overall layout, with the magnification level adjusting dynamically rather than being fixed. This dynamic adjustment capability resolves the contradiction between image detail visibility and overall layout view area by allowing the user to optimize the display for their current task.

AI summary
A computer of an image processing apparatus is provided with a computer-readable medium allowing the computer to execute: an image-obtain processing; a first display-control processing; a second display-control processing; a layout designation-judgment processing; a preview image-generation processing; and an operation-judgment processing. In the first display-control processing, the computer allows, on a condition that a print preview image is generated by the preview image-generation processing, the display screen to display the print preview image generated by the preview image-generation processing, instead of a previous print preview image previously displayed on the display screen; and in the first display-control processing, the computer allows the display screen to display the print preview image while magnifying or reducing the print preview image in a case that the computer judges, by the operation judgment processing, that two points on an image display device have moved away from each other or approached toward each other.
