Dynamic Exposure Control for Motion-Induced Image Blur
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with cameras, such as mobile phones and tablets, struggle to capture clear images in dim environments, especially when in motion, as the lowest shutter value does not guarantee image clarity due to movement.
Innovation Solution
Incorporating a sensor unit, like a GPS, to detect movement status and generate a movement parameter, which adjusts the exposure parameter threshold for the image capture unit, ensuring the exposure parameter is higher than the threshold to maintain image clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the electronic device uses the lowest shutter value to capture images in dim environments, then the image brightness is improved, but the image clarity deteriorates when the device is moving
Solution Approach 1:
The patent applies dynamics by making the shutter value adjustable based on movement status. Instead of using a fixed lowest shutter value, the system dynamically determines the shutter value according to the detected movement status of the electronic device, allowing optimal balance between brightness and clarity under different motion conditions
Solution Approach 2:
The patent implements feedback by using a sensor unit to detect the movement status of the electronic device and feeding this information back to the processor, which then adjusts the shutter value accordingly. This closed-loop control ensures the shutter value adapts to real-time movement conditions to maintain image clarity
2Illumination intensity
If the electronic device increases the exposure parameter to capture images in dim environments, then the image brightness is improved, but the exposure time increases causing motion blur
Solution Approach 1:
The system dynamically adjusts the exposure parameter based on movement status. When movement is detected, the processor determines an appropriate exposure parameter that balances brightness requirements with the need to limit exposure time, preventing motion blur while maintaining adequate image brightness
Solution Approach 2:
The patent changes the exposure parameter based on movement status detection. The processor modifies exposure parameters dynamically according to the sensor unit's detection results, allowing the system to adapt exposure time and other parameters to maintain both brightness and clarity under varying motion conditions
