Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cameras with fixed light sources struggle to maintain optimal image quality across different environments and installation positions, leading to issues such as overexposure or underexposure.
Innovation Solution
A light adjustment module with movable light-emitting units and reflective surfaces, controlled by actuators, adjusts the field of illumination based on environmental conditions and camera orientation to optimize image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed light source is used in the camera, then the structure is simple, but the image quality cannot be optimized for different environments and installation positions
Solution Approach 1:
The single fixed light source is divided into multiple light-emitting members that can be independently positioned. Each light-emitting member can be adjusted to different locations using actuators, allowing the system to adapt to various environmental conditions and installation positions without requiring a completely different lighting structure for each scenario.
Solution Approach 2:
The lighting system transitions from a static fixed position to a dynamic adjustable configuration. The actuators enable real-time repositioning of light-emitting members based on detected environmental conditions, allowing the camera to optimize image quality for different scenarios such as outdoor daytime, outdoor nighttime, indoor environments, and various mounting orientations.
2Reliability
If the camera uses a fixed light source configuration, then the device is simple to operate, but image quality deteriorates in certain environments such as indoor settings where overexposure occurs
Solution Approach 1:
The system incorporates environmental detection capabilities that provide feedback about the current operating conditions. Based on this feedback, the control system automatically adjusts the positions of light-emitting members to optimize illumination for the detected environment, ensuring consistent image quality across varying conditions without requiring manual intervention.
Solution Approach 2:
The lighting system changes its operational parameters by repositioning light-emitting members to different locations based on environmental conditions. This dynamic parameter adjustment allows the same physical hardware to deliver optimized performance across diverse scenarios, from bright outdoor environments to darker indoor settings, maintaining reliable image quality.

AI summary
A light adjustment module for a camera includes a substrate and a plurality of light adjustment assemblies. The substrate has a lens arrangement region. The light adjustment assemblies are spaced apart from each other and surround the lens arrangement region. Each of the light adjustment assemblies includes a light-emitting unit, a light-guiding member, and an actuator. The light-emitting unit includes a movable member and a light-emitting member, and the light-emitting member is on the movable member. The light-guiding member has a reflective surface facing the light-emitting member. The actuator is configured to drive the movable member to move with respect to the light-guiding member, so that the light-emitting member is moved toward or away from the light-guiding member. A camera including the light adjustment module is also provided.
