Solution Overview
Problem
Existing medical image processing technologies fail to accurately correct blurring caused by operator manipulation while preserving biological body motion, leading to incomplete observation of biological body movements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If blurring correction is performed based on manipulation situation information, then blurring suppression is improved, but biological body motion is removed
Solution Approach 1:
The patent segments motion into two distinct components: manipulation-induced motion (to be corrected) and biological body motion (to be preserved). By separating these motion types through frequency analysis and directional detection, the system applies different processing strategies to each component, correcting only the harmful manipulation-induced blurring while maintaining the informative biological body motion.
Solution Approach 2:
The patent applies local quality by directing blurring correction selectively based on motion characteristics. Instead of uniform correction across all motion, the system identifies specific motion patterns (manipulation-induced) and applies correction only to those regions/frequencies, leaving biological body motion unaffected. This localized approach ensures precise correction without information loss.
2Measurement precision
If strong blurring correction is applied, then image clarity is improved, but natural screen motion is removed
Solution Approach 1:
The patent implements dynamic gain adjustment that adapts correction strength based on real-time detection of motion characteristics. The correction gain varies dynamically according to the detected motion type and magnitude, allowing strong correction for manipulation-induced blurring while maintaining appropriate correction levels for biological body motion, thus preserving natural screen motion while improving clarity.
Solution Approach 2:
The patent changes the correction parameter (gain) based on detected motion characteristics. By monitoring manipulation situation information and adjusting the correction gain accordingly, the system optimizes the balance between clarity improvement and preservation of biological body motion, applying stronger correction when manipulation-induced blurring is detected and reducing correction when biological motion is present.

AI summary
[Object] To correct blurring without removing a screen motion caused by a biological body motion. [Solution] An image processing apparatus includes: a blurring amount estimation unit configured to estimate a blurring amount of a medical image including a biological body motion of a subject; and a blurring correction processing unit configured to perform blurring correction processing so as not to remove a screen motion caused by the biological body motion, on a basis of the blurring amount. This configuration makes it possible to correct blurring without removing a screen motion caused by a biological body motion. Thus, an optimum image for observing a biological body motion can be obtained.
