MFP Mixed-Size Document Detection and Preview Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image reading apparatuses struggle to accurately recognize and handle mixed-size documents, leading to image data being generated in sizes different from the document size, which can result in incorrect output, storage, and transmission, as users find it difficult to identify and rectify this issue without knowing the document size mixed mode.
Innovation Solution
An image reading apparatus equipped with a display, memory, and processor that successively conveys and reads documents, determines size differences, notifies users of potential mixed sizes through a preview screen, and provides navigation to re-read documents in the correct size mode, enabling the user to switch to document size mixed mode for accurate reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple preview display is used, then the display is simple and easy to implement, but the user cannot recognize that mixed size documents are read and image data size differs from document size
Solution Approach 1:
The patent applies visual indicators such as color coding and graphical icons on the preview screen to indicate size mismatches. When a document size differs from the expected size, the preview display changes color or displays specific icons to alert the user, making the size discrepancy immediately recognizable without complicating the overall display design
Solution Approach 2:
The patent introduces an intermediary indicator system between the document reading process and the user. This intermediary layer includes visual cues and notifications that translate the technical size mismatch information into user-friendly alerts, allowing users to recognize size issues without directly analyzing technical parameters
2Productivity
If document size mixed mode is not enabled, then the reading process is simple and fast, but image data is generated in size different from document size against user expectation
Solution Approach 1:
The patent performs preliminary detection of document sizes during the reading process and compares them against expected sizes before finalizing the output. This preliminary action allows the system to maintain simple reading operations while ensuring size accuracy by identifying and flagging mismatches early in the process
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors document sizes during reading and provides real-time feedback to the user through notifications and preview indicators. This feedback loop ensures that size discrepancies are detected and communicated, allowing users to correct the issue while maintaining efficient reading operations
3Ease of operation
If no navigation is provided, then the system operation is simple, but users unaware of document size mixed mode cannot find recovery method
Solution Approach 1:
The patent prepares recovery options in advance by pre-configuring the document size mixed mode and associated controls. When a size mismatch is detected, the system has the recovery mechanism ready and visible, allowing users to quickly switch modes without needing to search through complex settings or documentation
Solution Approach 2:
The patent introduces a navigation intermediary that guides users from the problem state (size mismatch notification) to the solution state (recovery method). This intermediary includes on-screen instructions and mode-switching controls that make the recovery process intuitive, maintaining system simplicity while improving user ability to find and execute recovery actions
Data Source
AI summary
A multifunction peripheral (MFP), which successively conveys a plurality of documents stacked on a document tray and reads the document, determines whether there is a difference among sizes of the plurality of documents in response to at least one of the documents being read by a scanner, in a case where a preview operation of a read image is performed, notifies a user of a possibility that documents having different sizes are mixed and read based on a result of the determination, enables a function of performing reading corresponding to respective document size of mixed size documents in which documents having different sizes are mixed, and provides navigation for prompting re-reading of the document.
