Remote Zoom Control for Manual Lenses via Motorized Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remote capturing with digital cameras equipped with manual zoom lenses lack the ability to remotely change the angle of view, as they rely on external mechanical adapters that face challenges in decision-making and operation control.
Innovation Solution
An electronic device with a communication unit, control unit, and display unit that communicates with an image capture apparatus to generate and transmit zoom control commands, obtain and display the current zoom position, and mechanically drive the zoom mechanism from outside the lens unit, enabling remote operation of manual zoom lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external mechanical adapter is used to drive a manual zoom lens for remote capturing, then the angle of view can be changed remotely, but the system complexity increases and decision-making control becomes difficult
Solution Approach 1:
The patent replaces the external mechanical adapter system with an integrated motor-driven zoom mechanism built into the lens unit. The motor-driven system substitutes the complex mechanical adapter structure, providing remote zoom control through electrical signals while eliminating the need for separate mechanical driving components outside the lens unit.
Solution Approach 2:
The patent merges the zoom driving mechanism directly into the lens unit by integrating a motor and drive mechanism within the lens itself. This consolidation combines the previously separate external adapter and manual zoom lens into a single integrated system, reducing overall device complexity while maintaining remote control capability.
2Measurement precision
If a motor-driven zoom mechanism is integrated into the lens unit, then remote control precision is improved, but the lens unit complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the lens control unit receives zoom position information from the drive mechanism and transmits this information to the external electronic device. This feedback loop enables precise control and monitoring of the zoom position, allowing the external device to accurately determine and adjust the zoom state while maintaining a relatively simple lens structure through intelligent control.
3Device complexity
If manual zoom lens is used in remote capturing system, then the lens structure remains simple, but the angle of view cannot be changed remotely
Solution Approach 1:
The patent transforms the static manual zoom lens into a dynamic system by incorporating a motor-driven mechanism that can be remotely controlled. The zoom mechanism transitions from a purely manual, fixed-state system to a dynamically controllable system that can adjust the angle of view in response to external control signals, enabling remote operation while maintaining structural efficiency.

AI summary
An electronic device generates, in accordance with an operation on an operation unit, a zoom control command for controlling a drive unit that mechanically drives a zoom position of a lens unit attached to an image capture apparatus from the outside of the lens unit, and transmits the zoom control command to the image capture apparatus via communication unit. The electronic apparatus obtains information related to the zoom position of the lens unit from the image capture apparatus, and displays, on a display apparatus, information indicating a current zoom position of the lens unit relative to a minimum zoom position and a maximum zoom position of the lens unit.
