Image Capture Method Using Three-Axis Acceleration Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held image capture devices require users to manually start and end operations, leading to potential failures and user inconvenience, especially due to accidental device movement or poor button contact, which can result in discontinuous images and reduced button lifespan.
Innovation Solution
An image capture method that utilizes three-axis acceleration sensors and optical mouse assemblies to detect acceleration values and image quality, automatically starting or finishing the capture operation when predetermined conditions are met, eliminating the need for manual button pressing and ensuring precise device status judgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual button pressing is used to start and end image capture, then the operation can be controlled, but the user experience deteriorates due to inconvenience and potential for accidental movements causing capture failures
Solution Approach 1:
The system automatically detects capture completion through sensors and terminates the capture operation without requiring manual button input. The device monitors its own state and self-manages the capture process, eliminating the need for users to press buttons to start or stop capture.
Solution Approach 2:
The patent replaces mechanical button pressing with sensor-based detection systems (accelerometers, gyroscopes, pressure sensors) to automatically determine when capture should begin and end. This substitution eliminates mechanical wear and user error associated with physical button operation.
2Ease of operation
If the power button is pressed multiple times or inadvertently during image capture, then the operation can be restarted, but the image capture quality deteriorates due to discontinuous images and multiple failed captures
Solution Approach 1:
The system continuously monitors sensor data during capture and provides feedback to determine whether capture conditions are still met. If the device is moved or the capture medium is removed, the sensors detect these changes and automatically terminate capture, preventing discontinuous images from multiple capture attempts.
Solution Approach 2:
The device autonomously monitors its own operational state through integrated sensors and self-corrects by terminating capture when conditions indicate the capture medium is no longer present or the device has been moved, preventing the need for user intervention that could cause capture errors.
3Adaptability or versatility
If the hand-held image capture device is moved during image capture, then the user can reposition the device, but the image capture quality deteriorates due to capture failures and discontinuous images
Solution Approach 1:
Accelerometers and gyroscopes continuously monitor device orientation and movement during capture. When sensors detect that the device has been moved beyond acceptable parameters or removed from the capture medium, the system receives feedback and automatically terminates capture, preventing image degradation from improper repositioning.
4Ease of operation
If the power button is pressed continuously or inadvertently, then the capture operation can be restarted multiple times, but the switch component lifespan deteriorates due to excessive mechanical wear
Solution Approach 1:
The patent replaces mechanical button pressing with electronic sensor-based detection and automatic termination. Since the system automatically detects when capture should end through sensor monitoring, the mechanical power button is never pressed during operation, eliminating wear and extending its operational life.
Solution Approach 2:
The device autonomously manages capture termination through sensor monitoring, eliminating the need for repeated manual button pressing. The system self-manages the capture lifecycle, preventing mechanical wear on the power button that would result from frequent user intervention.

AI summary
An image capture method includes steps of providing an image capture device, starting an image capture operation, detecting a first axial acceleration value, a second axial acceleration value, a third axial acceleration value and an image quality, and judging if any two of the first axial acceleration value, the second axial acceleration value and the third axial acceleration value exchange with each other. When the result of the judgement is False, the previous step of detection is re-performed, and when the result of the judgment is True, the next step of judging if the image quality is less than a predetermined value is performed. When the result of this judgement is False, the previous two steps of detection and judgement are re-performed, and when the result of this judgement is True, finishing the image capture operation. Therefore, the automatic finishing of the image capture is achieved without pushing any button.
