Mobile Terminal Image Smear Reduction via Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals, such as smartphones and cameras, often produce images with noticeable smear due to movement, as their fixed shooting parameters do not account for motion, leading to suboptimal image quality.
Innovation Solution
Determine the current shooting parameters based on the motion parameters of the mobile terminal, specifically adjusting exposure time and sensitivity, using internal sensors like accelerometers and light intensity sensors to minimize smear and ensure image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed shooting parameters are used in mobile terminal, then device complexity is reduced and ease of operation is improved, but image quality deteriorates due to smear caused by motion
Solution Approach 1:
The patent applies dynamics by transitioning from fixed shooting parameters to dynamic parameters that automatically adjust based on real-time motion detection. The system continuously monitors motion parameters through sensors and adapts shooting parameters (exposure time, shutter speed, ISO) accordingly, making the parameter set movable and responsive to changing conditions rather than static and fixed.
Solution Approach 2:
The patent implements feedback by using motion sensors to detect device movement and feeding this information back to the shooting parameter control system. This closed-loop feedback mechanism allows the system to sense motion conditions and automatically adjust exposure time and other parameters to compensate for motion-induced smear, resolving the contradiction between operational simplicity and image quality.
2Device complexity
If fixed shooting parameters are used in mobile terminal, then device complexity is reduced, but image quality deteriorates due to smear caused by motion
Solution Approach 1:
The patent applies self-service by enabling the shooting system to automatically adjust its own parameters based on motion detection without requiring manual user intervention. The system serves itself by using onboard sensors to detect motion and autonomously modifying exposure time, shutter speed, and ISO settings, thereby maintaining image quality without adding complex manual control interfaces.
Solution Approach 2:
The system transitions from static fixed parameters to dynamic adaptive parameters that automatically respond to motion conditions. This dynamic adjustment mechanism resolves the contradiction by allowing the system to maintain simple operation while achieving high image quality through real-time parameter optimization based on detected motion.
3Manufacturing precision
If exposure time is extended to improve image quality in low light, then image quality is improved, but smear increases when device is in motion
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting exposure time, shutter speed, and ISO sensitivity based on real-time motion detection. When motion is detected, the system reduces exposure time to minimize smear while compensating through increased ISO or adjusted shutter speed. This multi-parameter adjustment strategy resolves the contradiction between achieving adequate exposure for image quality and preventing motion-induced smear.
Solution Approach 2:
The patent implements preliminary anti-action by detecting motion before or during the shooting process and proactively adjusting parameters to prevent smear formation. The system anticipates the harmful effect of motion on image quality and takes corrective action by reducing exposure time or increasing sensitivity before the actual capture, thereby preventing rather than merely correcting the smear problem.
