Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform light intensity is used for the entire imaging target region, then the overall exposure is simplified, but the brightness of overlapping regions in composite images becomes inappropriate
Solution Approach 1:
The patent applies local quality by differentiating light irradiation intensity across different regions of the imaging target. Specifically, the first region (imaging region) receives higher light intensity than the second region (peripheral region), creating localized brightness enhancement where needed to ensure appropriate exposure in overlapping areas during composite image generation.
2Measurement precision
If higher light intensity is applied to the first region, then the exposure of overlapping imaging regions is improved, but the overall energy consumption increases
Solution Approach 1:
The system applies higher light intensity only to the first region where imaging is performed, while maintaining lower intensity for the second region. This localized approach ensures accurate exposure for the imaging area without unnecessarily increasing energy consumption across the entire imaging target region.
3Area of stationary object
If multiple imaging regions are captured and composited, then the coverage area is expanded, but the brightness consistency across overlapping regions deteriorates
Solution Approach 1:
The control device performs preliminary light irradiation control before capturing images in multiple regions. By pre-adjusting the light intensity to be higher in the first region and lower in the second region, the system ensures that when images are composited, the overlapping regions maintain appropriate brightness consistency, preventing brightness mismatches.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures appropriate brightness and composite image quality by adjusting light intensities and exposure amounts within overlapping imaging regions, resulting in improved image capture and processing efficiency.
Implementation Method 1
the light source irradiates the first imaging target region with light, and an intensity of the light with which the first region is irradiated is higher than an intensity of the light with which a periphery of the first region is irradiated

AI summary
A control device is a control device applied to a moving object equipped with an imaging apparatus and a light source. The imaging apparatus images a first imaging target region and a second imaging target region of a subject according to a movement position of the moving object. A first region that is a part of the first imaging target region overlaps with a second region that is a part of the second imaging target region. The control device includes a processor. The processor is configured to perform control of causing the light source to irradiate the first imaging target region with light. An intensity of the light with which the first region is irradiated is higher than an intensity of the light with which a periphery of the first region is irradiated.
