Preview Image Generation Using Identification Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing setting device requires time to display the setting screen due to the need to show reduced-size printing target images in the read image display area, making it inefficient for quick checking of page image arrangements on a sheet.
Innovation Solution
A display device with a receiving section for setting page image arrangements, a generating section that creates preview images using identification images smaller than the page images, and a display section to show these preview images, allowing users to quickly check the arrangement of page images on a sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reduced-size printing target images are displayed in the read image display area, then the arrangement of page images can be checked, but the time required to display the setting screen increases
Solution Approach 1:
The patent divides the page image into a thumbnail image (for display in the preview area) and the actual full-size image data (for printing). This segmentation allows the system to display multiple small thumbnail images simultaneously in the read image display area, enabling users to verify page image arrangements quickly without waiting for large full-size images to load.
2Measurement precision
If full-size page images are displayed to show arrangement details, then verification accuracy improves, but memory usage and display time increase
Solution Approach 1:
The patent creates thumbnail images as simplified copies of the original page images. These thumbnails retain the essential spatial arrangement information needed for verification but use significantly less memory. The system stores both the thumbnail images (for quick display) and the original full-size images (for actual printing), allowing efficient memory management while maintaining verification accuracy.

AI summary
A display device (1) includes a receiving section (11), a generating section (12), and a display section (40). The receiving section (11) receives an arrangement setting that is a setting by which a page image P is arranged in formation of the page image P on a sheet. The generating section (12) generates based on the arrangement setting a preview image (AP) in which an identification image D identifying the page image P is disposed. The display section (40) displays the preview image (AP). A location of the identification image D in the preview image (AP) indicates a location of the page image P when the page image P is formed on the sheet. The identification image D has a data size smaller than a data size of the page image P.
