Mobile Device Light Source Control for Lens Flare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for preventing lens flare in UAV cameras, such as using lens hoods, are inefficient and increase material costs, as different lenses require different hoods, affecting user experience and maintenance costs.
Innovation Solution
A mobile device control method that receives a photographing command and automatically turns off light sources affecting the camera's field of view, preventing lens flare without the need for lens hoods by integrating a light source control mechanism with the photographing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lens hood is used to prevent lens flare, then the photographing effect is improved, but the material cost and device complexity increase
Solution Approach 1:
The harmful light source (pilot lamp) is extracted and separated from the photographing system by turning it off during photographing, rather than adding a lens hood to block the light. This removes the source of lens flare without adding physical components to the optical path.
Solution Approach 2:
Instead of blocking the light path with a lens hood (adding something to prevent harm), the invention inverts the approach by removing the light source itself (turning off the pilot lamp). This prevents lens flare through subtraction rather than addition.
2Object-affected harmful factors
If different lens hoods are provided for different lenses, then the photographing effect is improved, but the manufacturing cost and maintenance cost increase
Solution Approach 1:
The solution of turning off the pilot lamp during photographing is universal and applies to all lenses without requiring lens-specific components. A single control mechanism (turning off the light source) works for all photographing scenarios, eliminating the need for multiple specialized lens hoods.
Solution Approach 2:
The invention changes the operational parameter of the light source (turning it off) rather than changing physical components for different lenses. This parameter-based control approach is universally applicable regardless of lens type, reducing manufacturing complexity.
3Object-affected harmful factors
If a lens hood is used to prevent lens flare, then the photographing effect is improved, but the user experience deteriorates due to poor versatility
Solution Approach 1:
The control method of turning off the pilot lamp during photographing is universally applicable to all lenses and photographing scenarios without requiring lens-specific accessories. This enhances versatility as users can photograph with any lens without needing to match specific hood types.
4Object-generated harmful factors
If the pilot lamp remains on during photographing, then the status indication function is maintained, but lens flare interferes with camera exposure
Solution Approach 1:
The system performs a preliminary action by turning off the pilot lamp before the photographing operation begins. This preemptive measure prevents lens flare from interfering with camera exposure, ensuring photographing quality without compromising the status indication function during non-photographing periods.

AI summary
A mobile device control method includes receiving a photographing command, turning off, in response to the photographing command, a light source affecting a photographing effect, and performing a photographing operation according to the photographing command.
