Document Stage Image Capture for Placement Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document reading apparatuses perform processes uniformly regardless of the document's placement on the stage, leading to unnecessary operations when the document is placed outside the optimal area.
Innovation Solution
An information processing apparatus that captures images of the document stage and adjusts processes based on the document's placement, such as position and orientation, to determine whether to perform reading and storage operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the apparatus uniformly performs reading processes regardless of document placement, then the reading function is always available, but unnecessary operations are performed when the document is placed outside the optimal area
Solution Approach 1:
The apparatus performs preliminary detection of document placement position and orientation before initiating the reading process. By detecting whether the document is placed within the readable area and checking its orientation, the system determines in advance whether to proceed with reading operations, thereby avoiding unnecessary energy consumption from operations that would not produce valid results
Solution Approach 2:
The apparatus provides feedback to the user about the document placement state through display screens or other output devices. This feedback mechanism informs users whether their document placement is appropriate for reading, allowing them to adjust the placement if needed. The system uses this feedback loop to prevent unnecessary reading operations and guide users toward proper document positioning
2Ease of operation
If the apparatus performs reading processes regardless of document placement form, then the system is simple to operate, but processes are performed even when documents are not optimally placed
Solution Approach 1:
The apparatus performs self-detection and self-judgment of document placement validity without requiring user intervention. The system automatically detects document position and orientation, judges whether the placement is appropriate for reading, and decides whether to proceed with the reading process. This self-service mechanism maintains operational simplicity while ensuring reading validity
3Productivity
If the apparatus detects and responds to document placement form, then reading operations are optimized, but the device complexity increases
Solution Approach 1:
The apparatus uses its existing image capture device to serve multiple functions: both capturing the document for reading and detecting the document's placement position and orientation. By making the image capture device multi-functional, the system avoids adding separate detection hardware, thereby optimizing reading operations while minimizing the increase in device complexity

AI summary
An information processing apparatus includes a processor configured to: obtain information about a form of placement of a document placed on a document stage of an apparatus that performs reading of the document by capturing an image of the document stage on which the document is placed; and change a process that is performed in association with reading of the document, in accordance with the form of placement of the document on the document stage.
