Scanned Page Preview Filtering With Manual Selection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading devices require high user labor for manual page selection when all pages are previewed, or reduce user freedom when automatic filtering is used, making it difficult to add or remove pages based on incorrect determinations.
Innovation Solution
An image reading device with a display unit showing selectable and deselectable preview images based on filter conditions, allowing users to manually select or deselect pages for inclusion in the final file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all pages are displayed as preview images, then the user can visually check every page, but the user labor increases significantly when the number of pages is large
Solution Approach 1:
The patent extracts and displays only the preview images of pages that satisfy the filter conditions (e.g., color pages, non-blank pages) rather than displaying all pages. This extraction approach reduces the number of preview images the user must review, thereby reducing user labor time while maintaining the ability to accurately select required pages.
2Loss of time
If automatic filtering is used to select pages, then the user labor is reduced, but the user's degree of freedom in page selection is reduced
Solution Approach 1:
The patent implements a dynamic preview display system where the user can interact with the displayed preview images. The user can manually select pages even if they are filtered out by automatic conditions, and can also deselect pages that were automatically selected. This dynamic interaction preserves user freedom while maintaining the benefits of automatic filtering.
3Productivity
If automatic filtering is used, then pages are automatically selected, but it becomes difficult for the user to manually add scanned pages that were erroneously determined not to satisfy conditions
Solution Approach 1:
The patent provides a feedback mechanism where the user can review the automatically filtered preview images and manually adjust the selection. The user can add pages that were erroneously excluded or remove pages that were incorrectly included, ensuring the final selection accurately reflects user intentions while maintaining high processing efficiency through automatic filtering.

AI summary
According to one embodiment, an image reading device includes a scanner configured to read documents that have a plurality of pages and generate image data for each page scanned. A display unit displays the preview images based on the image data from the scanner. An input unit is configured to receive input operations from a user. A controller is configured to cause the display unit to display preview images for pages of a document. The preview images are initially displayed as selected preview images or non-selected preview images according to whether the page corresponding to the preview image satisfies a filter condition or not. Each displayed preview image is selectable and deselectable by an input operation received via the input unit. The controller is further configured to generate a file including image data for the pages corresponding to the selected preview images.
