1Object-affected harmful factors

If inverse correction processing is performed to reduce crosstalk, then crosstalk inhibition is improved, but signal value clipping occurs beyond saturation constraints leading to incomplete correction

Engineering Contradiction:

ImprovecrosstalkVSAvoidcorrection precision

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The correction processing unit divides the correction process into multiple stages: inverse correction processing followed by additional correction processing. This segmentation allows the system to address signal clipping issues by applying different correction strategies to different parts of the correction process, thereby improving overall correction precision while maintaining crosstalk inhibition.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary inverse correction processing to reduce crosstalk, then evaluates correction residuals to identify regions requiring additional correction. This preliminary action followed by targeted additional correction ensures that signal clipping is minimized while maintaining effective crosstalk inhibition.

Inventive Principle:

Principle #10Preliminary action

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The cost evaluation unit evaluates correction residuals after inverse correction processing to determine whether additional correction is needed. This feedback mechanism allows the system to adjust the correction process dynamically, applying additional correction only where necessary to prevent signal clipping and maintain image quality while still achieving effective crosstalk inhibition.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary inverse correction processing to reduce crosstalk, then evaluates correction residuals to identify regions requiring additional correction. This preliminary action followed by targeted additional correction ensures that signal clipping is minimized while maintaining effective crosstalk inhibition.

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The correction processing unit performs additional correction processing only in regions where correction residuals exceed a threshold, rather than applying correction uniformly across the entire image. This partial action approach maintains high correction precision in critical areas while minimizing overall processing complexity.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The correction processing unit divides the correction process into multiple stages: inverse correction processing followed by additional correction processing. This segmentation allows the system to address signal clipping issues by applying different correction strategies to different parts of the correction process, thereby improving overall correction precision while maintaining crosstalk inhibition.
