Scanner GUI Document Placement Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanner technologies face challenges in accurately determining the position and orientation of documents on a scanner table, leading to increased manufacturing costs and user burden in obtaining desired scan results, particularly when multiple document sizes and orientations are involved.
Innovation Solution
A computer-readable storage medium program that creates a GUI screen displaying the position and orientation of a document on the scanner table, using first information about the document table and user-designated document size, to guide the user in placing the document correctly, thereby simplifying the configuration and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple optical sensors are installed at different positions to detect document presence and determine document size, then document size detection capability is improved, but manufacturing cost of the scanner main body is increased
Solution Approach 1:
The patent uses a single optical sensor to capture an image of the document, then processes this image data to determine document size and position. This replaces the need for multiple physical sensors with a digital copy (image) of the document, reducing hardware complexity while maintaining detection capability.
Solution Approach 2:
A single optical sensor serves multiple functions: detecting document presence, determining document size, and identifying document position. This multi-functional approach eliminates the need for separate sensors for each detection task, reducing manufacturing cost while improving overall system efficiency.
2Ease of operation
If a preview screen is displayed to allow users to check the scanned image and determine document size, then ease of operation is improved, but processing time is increased due to creation of preview and scan repetition
Solution Approach 1:
The system performs preliminary detection of document size and position using the optical sensor before the actual scanning process. This preliminary action provides users with document placement information in advance, allowing them to adjust placement if needed before scanning, thereby avoiding the need to create full preview screens and reducing repeated scanning.
3Ease of operation
If marks corresponding to document sizes are attached to the edge of the document table to guide users, then ease of operation is improved, but adaptability is reduced because it is difficult to attach all kinds of mark for different document sizes
Solution Approach 1:
The patent replaces the mechanical approach of attaching physical marks to the document table with an optical/electronic solution. The optical sensor captures document placement information, and software processes this data to provide guidance, eliminating the need for physical marks while maintaining user guidance capability and increasing adaptability to various document sizes.
4Ease of operation
If a liquid crystal panel is used as the document table to display document placement position, then ease of operation is improved, but manufacturing cost is increased
Solution Approach 1:
Instead of using a liquid crystal panel to display document placement information, the patent uses a standard display unit to show guidance information based on optical sensor data. This replaces the expensive liquid crystal panel with a conventional display, reducing manufacturing cost while maintaining the ability to provide visual feedback on document placement.

AI summary
An object of the present disclosure is to present a document placement position more simply. A program for causing a computer of an information processing apparatus that causes an image processing apparatus to perform document scan processing to function as: a creation unit configured to create, based on first information relating to a document table of the image processing apparatus, second information indicating a position of a scan origin on the document table, and third information indicating a document size designated by a user, a GUI screen including information for guiding a position at which the document is placed on the document table; and a display control unit configured to cause a display unit to display the created GUI screen.
