Document Scanner Hinge Detection for Automatic Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses require precise adjustment of hinge angles and visual confirmation for photographing documents, leading to incomplete or failed captures when the cases are closed without the specific operation, and lack the ability to retake images.
Innovation Solution
An information processing apparatus with an imaging section, detection section, acquisition section, correction section, and storage section that automatically detects the closure state of the cases, acquires images, performs distortion correction, and stores them securely by closing the first and second cases, using sensors and image analysis to ensure clear photography.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second case is held at a predetermined hinge angle for a predetermined amount of time, then the document can be photographed, but the operation becomes complex and the user must visually confirm the photographed image
Solution Approach 1:
The system automatically detects the closing action and triggers photographing without requiring user confirmation or manual intervention. The detection section monitors the hinge angle and automatically activates the imaging section when the predetermined closed state is detected, making the system self-sufficient and eliminating the need for visual confirmation by the user.
Solution Approach 2:
The detection section continuously monitors the hinge angle and provides feedback to the control section. When the feedback indicates the predetermined closed state is achieved, the system automatically initiates photographing. This closed-loop feedback mechanism ensures reliable detection while simplifying user operation.
2Volume of moving object
If the cases are closed without performing the specific operation, then the device is compact, but the document is not photographed
Solution Approach 1:
The system automatically detects when the cases are closed and triggers photographing without requiring any specific user operation. The detection section monitors the hinge angle and automatically activates the imaging function when the closed state is detected, making the system self-sufficient and ensuring documents are captured regardless of user behavior.
Solution Approach 2:
The detection section is continuously monitoring the hinge angle in advance, so when the cases are closed, the system can immediately detect and trigger photographing. This preliminary monitoring ensures that the photographing function is activated automatically when needed, without requiring prior user preparation or specific operations.
3Measurement precision
If the hinge angle is strictly adjusted to photograph the document, then the document can be captured, but the system lacks adaptability to different closing states
Solution Approach 1:
The system dynamically adapts to different closing states by detecting the hinge angle and determining whether it matches the predetermined closed state. Rather than requiring strict manual adjustment, the system flexibly identifies the correct state through detection and automatically triggers photographing when the document is properly positioned, providing both precision and adaptability.

AI summary
An information processing apparatus having first and second cases (13a, 13b) that are openably/closably connected, and includes an imaging section (6) provided in the second case and opposed to the first case where a read target medium is placed, a detection section (1) which detects that the first and second cases have been closed into a predetermined state by plural types of methods, an acquisition section (1) which acquires a photographed image from the imaging section when the detection section detects that the first and second cases have been closed into the predetermined state by the plural types of methods, a correction section (1) which performs distortion correction processing on the photographed image acquired by the acquisition section, based on a closing state between the first and second cases detected by the detection section, and a storing section (3) which stores the photographed image corrected by the correction section.
