Dual-Lens Movement Control for Seamless Auto Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-lens systems either prevent full center view by offsetting the wide-angle lens when the telescope's viewing angle changes or restrict the wide-angle lens to detection purposes, failing to effectively utilize the wide viewing angle and resulting in inaccurate auto framing during automatic tracking.
Innovation Solution
A dual-lens movement control system comprising a wide-angle lens, a telescope, and a motor device connected to a processor that detects tracking targets, calculates a final tracking range, and determines a separate mode or alignment mode to optimize the movement and magnification of both lenses for seamless image switching and auto framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the wide-angle lens and telescope are fixed on the same structure and move together, then the structure is simple, but when the telescope's viewing angle changes, the wide-angle lens is offset and full center view is prevented
Solution Approach 1:
The patent divides the lens system into two independently controllable units: the wide-angle lens and the telescope. Each lens can be controlled by separate motors to adjust their positions and viewing angles independently, allowing the wide-angle lens to maintain center view while the telescope changes its viewing angle without offsetting the wide-angle lens.
2Device complexity
If the wide-angle lens is fixed and only used for detection, then the structure is simple, but the wide viewing angle advantage cannot be effectively utilized
Solution Approach 1:
The patent transforms the fixed wide-angle lens into a dynamically adjustable component. The wide-angle lens is equipped with independent motor control to adjust its position and viewing angle, enabling it to actively capture wide-angle scenes rather than being passively fixed for detection only. This dynamic adjustment allows the system to switch between wide-angle and telephoto views seamlessly.
3Ease of operation
If the wide-angle lens and telescope move independently, then the viewing flexibility is improved, but the auto framing accuracy deteriorates
Solution Approach 1:
The patent implements a feedback control system where the processor receives real-time position information from both the wide-angle lens and the telescope. Based on this feedback, the processor calculates the final tracking range and determines the appropriate magnification and position for optimal framing. This closed-loop control ensures that independent movement of both lenses does not compromise auto framing accuracy, as the system continuously adjusts based on actual positions.
4Stability of the object's composition
If the wide-angle lens returns to center when telescope returns, then the alignment is maintained, but the edge view capability is lost
Solution Approach 1:
The patent segments the control of the wide-angle lens and telescope into independent systems. The wide-angle lens can be positioned independently to capture edge views while the telescope handles the main tracking function. This segmentation allows the system to maintain alignment when needed while also capturing edge views without requiring the wide-angle lens to return to center automatically.

AI summary
The present disclosure provides a dual-lens movement control method, which includes steps as follows. The tracking target is detected through the wide-angle lens, and the final tracking range is calculated; the magnification and the position are determined according to the final tracking range; the separate mode or the alignment mode is determined according to the magnification and the position.
