Image Correction Unit for Positional Deviation in Mixed Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to effectively correct positional deviations in image formation, particularly affecting line elements, as uniform methods for inserting or deleting pixels cannot inhibit deterioration in output images with mixed characteristics like character and frame lines.
Innovation Solution
An image processing device and method that includes an image correcting unit capable of inserting or deleting pixels based on size changing information, utilizing a characteristic determining unit to classify areas and select appropriate deforming processes such as neighborhood pixel moving or averaging, to correct positional deviations while preserving line element quality.

Engineering Contradiction Analysis
1Ease of operation
If a uniform method is used to insert or delete pixels for positional deviation correction, then the correction process is simple, but line element deterioration occurs in the output image
Solution Approach 1:
The patent applies local quality by classifying different regions of the image (character areas, graph areas, picture areas) and applying different deforming processes to each region. The characteristic determining unit identifies whether a pixel belongs to a line element based on peripheral pixel values, and the deforming process selecting unit chooses appropriate processing methods (such as different interpolation methods) for different regions, thereby preserving line element quality while correcting positional deviation.
2Manufacturing precision
If different deforming processes are selected for different image characteristics, then line element quality is preserved, but the device complexity increases
Solution Approach 1:
The patent segments the image processing into distinct functional units: a reading unit that reads pixel data, a characteristic determining unit that classifies pixel types based on peripheral values, a deforming process selecting unit that chooses appropriate processing methods, and a correction executing unit that applies the selected process. This segmentation allows the system to handle complexity through modular design while maintaining line element quality.
