Distance-Aware Image Fluctuation Correction with Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image fluctuation correction methods, such as smoothing in the time direction, often result in moving object blur and inaccurate fluctuation detection due to environmental changes, especially when moving objects or devices are present in the input image.
Innovation Solution
An image processing apparatus and method that utilizes fluctuation information acquisition, decision units to determine correction strength based on focal length and object distance, and correction units to apply appropriate fluctuation correction, minimizing moving object blur while accurately detecting and correcting image fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image smoothing is applied in the time direction to reduce fluctuation, then fluctuation correction is improved, but moving object blur occurs
Solution Approach 1:
The patent applies different processing to different regions of the image: stationary objects undergo time-directional smoothing for fluctuation correction, while moving objects are detected and excluded from this smoothing process. This local differentiation resolves the contradiction by applying fluctuation correction only where needed without blurring moving objects.
Solution Approach 2:
The patent dynamically adjusts the processing based on object motion state. By detecting whether objects are moving or stationary in each frame, the system adaptively applies or skips smoothing operations, allowing optimal fluctuation correction for stationary objects while preserving moving object clarity.
2Measurement precision
If fluctuation detection is based on pixel value difference to adapt to environmental changes, then fluctuation detection accuracy is improved, but false detection of moving objects as fluctuation occurs
Solution Approach 1:
The patent segments the image processing into two independent pathways: fluctuation detection for stationary objects and moving object detection. By separating these functions, the system can accurately detect atmospheric fluctuation without mistaking moving objects for fluctuation, as each pathway processes specific object types independently.
Solution Approach 2:
The patent uses moving object detection feedback to modulate the fluctuation correction process. When moving objects are detected, the system adjusts or disables fluctuation correction for those regions, preventing false correction based on erroneous pixel value differences caused by object motion.
