Preview Screen Display for Multi-Page Scanned Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses struggle to display preview screens for scanned documents that include multiple pages, making it difficult for users to recognize the presence of preceding or succeeding pages.
Innovation Solution
An image processing apparatus that displays a preview screen showing the image data of a first page as editable, along with an image representing one or more subsequent pages, using either a first image for a single subsequent page or a second image for multiple subsequent pages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the image data corresponding to one page is displayed on the preview screen, then the display is simple and clear, but the user cannot recognize whether there are other pages before and after the displayed page
Solution Approach 1:
The patent divides the display area into multiple regions: a first display region showing the current page image data and a second display region showing thumbnail images of other pages. This segmentation allows the system to display both current page information and other page information simultaneously without overwhelming the user, resolving the contradiction between information completeness and display simplicity.
Solution Approach 2:
The patent adds a spatial dimension to the display by introducing a second display region that shows thumbnail images of other pages. This transforms the display from a single-dimension (one page at a time) to a multi-dimensional layout where users can see the current page and other pages simultaneously, thereby preventing information loss without significantly increasing complexity.
2Loss of information
If image data of multiple pages is displayed on the preview screen, then the user can recognize other pages, but the display becomes complex and difficult to understand
Solution Approach 1:
The patent applies different display qualities to different regions: the first display region shows high-quality image data of the current page for detailed viewing and editing, while the second display region shows lower-quality thumbnail images of other pages for quick reference. This local quality differentiation allows users to see multiple pages without compromising the clarity and ease of operation for the current page.
3Loss of information
If the user navigates through multiple pages sequentially, then each page can be viewed clearly, but the operation time and waiting time increase
Solution Approach 1:
The patent generates and displays thumbnail images of all pages in advance in the second display region, before the user needs to navigate to them. This preliminary action allows users to see all pages simultaneously and quickly jump to any page without sequential navigation, significantly reducing navigation time and waiting time while maintaining complete page information visibility.

AI summary
An image processing apparatus includes one or more memories storing instructions, and one or more processors executing the instructions to display a preview screen on which, among image data of a plurality of pages of a document obtained by scanning the document, image data of a first page is displayed as image data to be edited, and an image corresponding to one or more subsequent pages after the first page is further displayed. In a case where a number of the one or more subsequent pages after the first page is one, a first image is displayed as the image corresponding to the one or more subsequent pages, and in a case where the number of the one or more subsequent pages after the first page is plural, a second image is displayed as the image corresponding to the one or more subsequent pages.
