Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in capturing ultra-wide angle and panoramic images with fish-eye lenses, which have a high imaging deformation rate and wide capturing angle, making it difficult to achieve smooth images when focusing on specific subjects in small areas.
Innovation Solution
A multiple lens system with two lens units, each comprising two symmetrically positioned lenses (fish-eye and normal lenses), and a reflection module with rotating reflection elements that adjust optical paths to select different capturing modes, allowing for ultra-wide angle, normal, front fusion, and rear fusion capturing modes with controlled imaging deformation.

Engineering Contradiction Analysis
1Area of moving object
If fish-eye lenses are used to capture ultra-wide angle or panoramic images, then the capturing angle is widened, but the imaging deformation rate increases and image smoothness deteriorates when focusing on specific subjects in small areas
Solution Approach 1:
The patent divides the lens system into multiple independent lens units (first lens unit with first lens, second lens unit with second lens) that can be selectively activated. Each lens unit captures images with different field of views and deformation characteristics, allowing the system to segment the capturing task between ultra-wide angle coverage and controlled deformation zones.
Solution Approach 2:
The patent implements dynamic switching between different lens units and capturing modes (ultra-wide angle mode, normal mode, front fusion mode, rear fusion mode) based on the captured image's field of view and subject characteristics. This dynamic adaptation allows the system to optimize image quality for different scenarios rather than using a fixed lens configuration.
2Adaptability or versatility
If fish-eye lenses are used to achieve wide capturing angle, then panoramic coverage is improved, but the imaging deformation rate becomes too high for preferred image quality
Solution Approach 1:
The system segments the imaging function across multiple lens units with different optical characteristics. The first lens unit provides ultra-wide angle coverage with controlled deformation, while the second lens unit provides normal angle coverage with minimal deformation, allowing the system to segment the deformation control task.
Solution Approach 2:
The patent changes the optical parameters by switching between different lens units and capturing modes. By adjusting which lens unit is active and which capturing mode is used, the system can control the imaging deformation rate while maintaining panoramic coverage capability when needed.
3Manufacturing precision
If multiple lens units and capturing modes are implemented, then image quality and deformation control are improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal lens system where multiple lens units and capturing modes serve different imaging needs within a single device. The same lens system can perform ultra-wide angle capture, normal angle capture, front fusion, and rear fusion modes, making the complexity serve multiple functions rather than requiring separate dedicated systems.
Solution Approach 2:
The system uses dynamic switching mechanisms to manage complexity by activating only the necessary lens units and capturing modes for each specific imaging task. This dynamic configuration allows the system to simplify the active path for each operation while maintaining the capability for complex multi-mode operation when required.
