External Lens Control for Mobile Camera Zoom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as mobile phones, face limitations in camera functionality due to space constraints, which prevent the integration of optical zooming lenses, resulting in lower image quality compared to consumer digital cameras.
Innovation Solution
A method and system that allows a main device to control an external lens by installing a control program, enabling enhanced camera functions such as auto-focusing, focal length adjustment, and image processing, using the device's existing resources like battery and memory to improve camera functionality without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an optical zooming lens is integrated into the portable electronic device, then image quality is improved, but device volume increases
Solution Approach 1:
The patent extracts the optical zooming lens from the portable electronic device and places it in an external device. The main device communicates with the external lens device through a connection interface, allowing the external lens to perform optical zooming functions while the main device maintains its compact size. This resolves the contradiction by separating the bulky optical components from the portable device while retaining the image quality benefits.
2Adaptability or versatility
If an optical zooming lens is configured in the portable electronic device, then camera function is enhanced, but available space is reduced
Solution Approach 1:
The patent introduces an external lens device as an intermediary between the user and the main device's camera function. The external lens device contains the optical zooming lens and communicates with the main device through a connection interface, enabling enhanced camera functions without occupying space within the main device's housing.
3Adaptability or versatility
If a control program is installed in the main device, then compatibility with different operating systems is improved, but device memory usage increases
Solution Approach 1:
The patent extracts the control program from the main device and places it in the external lens device. The external lens device runs the control program locally to manage communication and operations, while the main device only needs basic driver software. This significantly reduces the memory burden on the main device while maintaining compatibility across different operating systems through the external device's autonomous control capability.

AI summary
A method and a system for controlling an external lens, applicable to a main device to control a lens module connected thereto, are provided. The main device provides power and storage medium for the lens module to use. In the present method, the lens module is connected to the main device, and a control program is downloaded from a memory unit of the lens module and installed in the main device. The control program is used to allow the main device to receive a control operation, accordingly control the lens module to execute a camera function, and finally display an execution result of the lens module executing the camera function.
