Image Display Unit Previewing Document Size and Color Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses require users to manually check for changes in document size and color type during the scanning process, leading to unnecessary user confirmation and potential errors due to the lack of efficient preview display of input conditions.
Innovation Solution
An image display unit that compares successive pages of image data to detect changes in document size and color type, allowing for simultaneous display of the changed image data and the previous or next page's data on a preview display, enabling users to easily confirm changes and ensure optimal image output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional apparatuses successively compare documents and ask user confirmation when changes are found, then user awareness of document changes is improved, but user operation time and complexity increase
Solution Approach 1:
The system performs preliminary comparison of document characteristics (size, color type) during the scanning process and automatically identifies changes before user intervention is needed. The preview display unit pre-prepares to show both the current and previous pages, eliminating the need for users to manually check changes after scanning.
Solution Approach 2:
The system creates a visual copy of both the current scanned page and the previous page in the preview display unit. This copying mechanism allows users to simultaneously view and compare document characteristics without physically handling documents or performing manual comparison operations.
2Loss of information
If conventional apparatuses warn users to check document changes, then information about document status is provided, but users still must manually verify changes
Solution Approach 1:
Instead of merely warning users about potential changes, the system creates visual copies of both current and previous pages in the preview display unit. This allows users to directly observe and verify changes by viewing the displayed images, transforming abstract warnings into concrete visual comparisons.
Solution Approach 2:
The preview display unit acts as an intermediary between the scanning system and the user. It receives image data from the scanner, compares document characteristics, and presents visual information that mediates the user's understanding of document changes, eliminating the need for manual verification.
3Reliability
If the system displays only current page when color type changes, then current document status is shown, but comparison with previous page becomes difficult
Solution Approach 1:
The system merges the display of current and previous pages in a single preview display unit. By combining both pages in the same viewing space, the system enables users to simultaneously observe the current document status and compare it with the previous page, making change detection intuitive and straightforward.
Solution Approach 2:
The system adds a temporal dimension to the display by showing both the current page and the previous page simultaneously in the preview display unit. This dimensional expansion from single-page to multi-page display enables users to perceive changes across time without additional cognitive load or manual manipulation.
Data Source
AI summary
An image display unit capable of displaying image data page-wise includes: a scanner portion; a display panel for displaying input image data in preview representation; an input condition determiner that compares the image data successively input through the scanner portion, as to input condition and determines whether there is any change in the image data input condition; and a display controller that, when the input condition determiner determines that the input image data has changed in the input condition, makes control such as to display the image data that was determined to have changed in the input condition and the image data input immediately before the image data in question, together on the display panel.
