Image Measurement Sheet for Automatic Image Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in accurately correcting image deviations such as positional, size, and density issues on recording media due to lack of efficient measurement and correction methods.
Innovation Solution
An image measurement sheet with medium scan windows, image scan windows, and an information scan window is used to detect recording medium and image conditions, allowing for precise image correction by scanning and processing imaging condition information to determine if within a given time period for correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual image correction methods are used, then operators can adjust image parameters, but operator workload increases and data errors may occur
Solution Approach 1:
The system automatically performs image measurement and correction by scanning the measurement sheet and processing the captured data through circuitry, eliminating the need for manual operator intervention in image correction tasks while maintaining high precision through automated calculation of correction conditions
Solution Approach 2:
The patent replaces manual mechanical measurement and adjustment operations with an automated optical scanning system that captures image data through scan windows and uses circuitry to compute correction parameters, substituting human operators with an automated measurement and control system
2Measurement precision
If multiple scan windows are used to detect various image parameters, then measurement comprehensiveness improves, but device complexity increases
Solution Approach 1:
The measurement sheet is divided into multiple functional scan windows (first scan window for image data, second scan window for measurement data, third scan window for correction conditions) that can be independently designed and positioned, allowing comprehensive measurement coverage while maintaining modular simplicity in the overall structure
Solution Approach 2:
The measurement sheet serves multiple functions simultaneously by incorporating different scan windows that detect various parameters (image position, size, density, and correction conditions) in a single integrated structure, eliminating the need for separate measurement devices for each parameter type
