Camera Control Apparatus for High-Speed Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems struggle to capture moving objects at high speeds under low illumination conditions, resulting in poor visibility and noise in captured images due to shortened exposure periods.
Innovation Solution
A control apparatus that determines the moving speed of an object and adjusts the image capturing method by performing panning or tilting to maintain exposure periods suitable for image quality, rather than shortening exposure times, ensuring clear and noise-reduced images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the exposure period is shortened to capture high-speed moving objects, then motion blur is reduced, but image brightness and sensitivity deteriorate under low illumination
Solution Approach 1:
The patent applies dynamics by making the image capturing system movable through panning and tilting operations. The monitoring camera dynamically adjusts its orientation to follow high-speed moving objects, allowing the use of longer exposure periods without causing motion blur, thereby maintaining image brightness and sensitivity under low illumination conditions.
Solution Approach 2:
The patent changes the parameter of exposure period from short to long when capturing high-speed objects. By combining this parameter change with panning/tilting control to track the moving object, the system achieves both motion clarity and sufficient image brightness, resolving the contradiction between speed capture and illumination intensity.
2Speed
If the exposure period is shortened to capture high-speed moving objects, then motion blur is reduced, but image quality deteriorates with increased noise
Solution Approach 1:
The system dynamically tracks high-speed moving objects using panning and tilting movements. This dynamic following capability allows the use of longer exposure periods that maintain image quality with adequate brightness and reduced noise, while still capturing fast-moving objects clearly.
Solution Approach 2:
The patent implements feedback control by continuously monitoring the position of moving objects and adjusting the camera's panning and tilting angles in real-time. This feedback mechanism ensures the object remains centered in the frame during longer exposure periods, maintaining both motion clarity and image quality with reduced noise.
3Manufacturing precision
If panning or tilting is performed to follow high-speed moving objects, then image quality is maintained with longer exposure periods, but the complexity of the control system increases
Solution Approach 1:
The patent makes the monitoring camera multi-functional by integrating both image capture and active tracking capabilities in a single system. The camera performs both standard monitoring and dynamic following of moving objects, eliminating the need for separate tracking devices and reducing overall system complexity despite the added control functions.

AI summary
A control apparatus obtains the moving speed of an object, and controls, based on the moving speed of the object, an image capturing unit configured to capture the object such that first image capturing for performing image capturing without following the object or second image capturing for performing image capturing while following the object is performed.
