Imaging Support Device Dynamic Exposure Control for Moving Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging technologies struggle to set an optimal exposure time for imaging specific parts of a subject, particularly when the dimension of the specific part varies, leading to suboptimal image quality due to shake and blurriness.
Innovation Solution
An imaging support device that includes a processor to derive an allowable shake amount based on the dimension of a specific part and pixel resolution, and then sets an exposure time for the image sensor based on the moving speed of the object and the allowable shake amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If exposure time is extended to capture sufficient light, then image brightness is improved, but shake and blurriness increase
Solution Approach 1:
The patent dynamically adjusts exposure time based on the dimensions of specific parts in the subject. By calculating the relationship between subject dimension, imaging distance, and exposure time, the system optimizes exposure parameters in real-time to balance brightness and sharpness requirements
Solution Approach 2:
The system changes exposure time parameters based on detected subject characteristics. When small dimensions are detected, exposure time is reduced to prevent shake blur; when large dimensions are detected, exposure time can be extended for sufficient brightness
2Manufacturing precision
If exposure time is shortened to reduce shake blur, then image sharpness is improved, but image brightness decreases
Solution Approach 1:
The system adjusts exposure time parameters based on detected subject characteristics. When small dimensions are detected, exposure time is reduced to prevent shake blur; when large dimensions are detected, exposure time can be extended for sufficient brightness
Solution Approach 2:
The system uses feedback from subject dimension detection to automatically adjust exposure time. The imaging support device calculates appropriate exposure parameters based on the relationship between subject size and shake amount, creating a closed-loop control system
3Ease of operation
If exposure time is set without considering subject dimension, then imaging process is simplified, but image quality deteriorates
Solution Approach 1:
The imaging support device automatically performs subject dimension detection and exposure time calculation without requiring manual intervention. The system self-adjusts exposure parameters based on detected subject characteristics, eliminating the need for operator expertise while maintaining high image quality
Solution Approach 2:
The system automatically changes exposure time parameters based on detected subject dimensions, transforming a complex manual adjustment process into an automated parameter optimization system

AI summary
An imaging support device is an imaging support device that supports imaging performed by an imaging device mounted in a moving object. The imaging device includes an image sensor. The imaging support device includes a processor. The processor derives a shake amount that is allowable for a subject image formed on the image sensor in a state in which the moving object is moving, based on a dimension of a specific part included in a subject and pixel resolution, and derives an exposure time for the image sensor based on a moving speed of the moving object and the shake amount.
