Scrollable Preview Display for Page Reordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image editing apparatuses with preview display functions face difficulties in efficiently reordering and managing multiple page images, particularly when the number of pages is large, as the current methods require cumbersome scrolling and struggle to select and move pages to arbitrary positions simultaneously.
Innovation Solution
An image editing apparatus with a display device showing preview images in a scrollable manner, a separate selected page display for easy identification of selected pages, and editing capabilities that allow users to change page order by dragging and dropping images, enabling simple and clear operations for reordering, deleting, and inserting pages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of page images is large and scrolling is used to navigate, then all pages can be displayed, but the amount of scrolling increases and operation becomes troublesome
Solution Approach 1:
The display area is segmented into two independent regions: a preview display region showing multiple page images in scrollable manner, and a selected page display region showing the currently selected page image. This segmentation allows users to navigate through many pages via scrolling in the preview region while the selected page remains continuously visible in the separate display region, eliminating the need for excessive scrolling to maintain context.
Solution Approach 2:
A separate selected page display region acts as an intermediary between the scrollable preview display and the user's editing operations. This intermediary continuously shows the selected page image regardless of scrolling position, serving as a stable reference point that mediates between the dynamic preview display and the user's need to confirm page content during reordering operations.
2Productivity
If thumbnail display is used to confirm page order, then space is saved, but it is difficult to confirm contents of each page image
Solution Approach 1:
Different display regions are assigned different quality levels: the preview display region uses thumbnail-sized images to show overall page order and allow efficient scrolling through many pages, while the selected page display region provides a larger, higher-quality display of the currently selected page image for content confirmation. This local quality differentiation allows users to efficiently manage page order while maintaining the ability to confirm image contents when needed.
3Adaptability or versatility
If conventional drag-and-drop scrolling method is used, then page order can be changed, but a plurality of pages positioned away from each other cannot be selected at once
Solution Approach 1:
The selected page display region creates a copy or representation of the selected page image that remains stationary and independently visible regardless of scrolling position in the preview display. This copying mechanism allows users to select multiple pages at different positions by scrolling through the preview display while continuously confirming the selected page(s) in the separate display region, enabling versatile page selection without complex operations.

AI summary
An image editing apparatus allowing easy edition of page arrangement order on the preview display of page images includes a display device having a display screen and a preview display device configured to display image data in a scrollable manner. If any page is selected from the images of preview display, the selected page is displayed as a reduced image at a position different from the preview images. By drag-and-dropping the reduced image to an arrangement of preview images, the selected page moves to the drag-and-dropped position in the image data.
