Information Processing for Image Inspection with Nozzle Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection apparatuses fail to consider non-ejection correction information when inspecting images formed by image forming apparatuses, leading to inadequate inspection performance.
Innovation Solution
An information processing system that transmits correction information related to non-ejection correction, including execution, position, and user-set accuracy information, to an inspection apparatus to enable informed inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the inspection apparatus scans the image without considering non-ejection correction information, then the inspection process is simple and fast, but the inspection accuracy deteriorates because it cannot distinguish between actual defects and areas affected by non-ejection correction
Solution Approach 1:
The inspection apparatus receives correction information about non-ejection nozzles and their positions before performing the inspection. This preliminary acquisition of correction data allows the inspection process to account for non-ejection correction areas, improving accuracy without requiring complex real-time adjustments during scanning
Solution Approach 2:
Correction information acts as an intermediary between the image forming apparatus and the inspection apparatus. This intermediate data layer provides context about non-ejection correction areas, enabling the inspection apparatus to interpret scan results accurately without directly modifying its scanning mechanism
2Measurement precision
If the inspection apparatus transmits and processes correction information, then the inspection accuracy improves, but the information transmission and processing load increases
Solution Approach 1:
The system extracts only the essential correction information needed for inspection - specifically data about non-ejection nozzles and their positions - rather than transmitting complete image data or all operational parameters. This selective extraction minimizes information overhead while maintaining inspection accuracy
Solution Approach 2:
The correction information focuses on specific local areas where non-ejection correction is applied, rather than providing global image data. This localized approach transmits only the necessary information about affected regions, reducing overall data transmission requirements
