Image Processing Apparatus Thin Line Fill Figure Reproducibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing devices struggle to reproduce small closed areas, such as thin lines, effectively due to limitations in printer engine characteristics, and existing solutions fail to apply thickening processes to line figures created without line drawing commands or consider adjacent line figures.
Innovation Solution
An image processing apparatus with a drawing command determination section that identifies thin line fill figures and a line width correction section to apply a thickening process, enhancing reproducibility by correcting line widths and considering the type and position of drawing commands, including both line drawing and closed region fill commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a thickening process is applied to improve the reproducibility of thin lines, then the manufacturing precision of line figures is improved, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies local quality by selectively thickening only specific line figures that meet certain criteria (thin lines with closed regions) while leaving other line figures unchanged. The line width correction section determines whether to apply thickening based on the specific characteristics of each drawing command, ensuring that thickening is applied locally where needed rather than universally to all lines.
Solution Approach 2:
The patent changes the line width parameter of specific drawing commands to improve reproducibility. The line width correction section modifies the line width attribute of thin line fill figures by a predetermined amount, transforming the original line width parameter into a corrected value that ensures better reproduction quality on the printer engine.
2Manufacturing precision
If the line width is corrected to thicken thin lines, then the manufacturing precision is improved, but the processing time increases due to additional correction steps
Solution Approach 1:
The patent performs preliminary action by applying the thickening process during the image generation phase, before the actual printing operation. The line width correction is performed in advance as part of the drawing command processing, so that when the corrected image data is sent to the printer engine, no additional processing time is required during the printing operation itself.
Solution Approach 2:
The image generation device performs self-service by automatically detecting thin line fill figures and applying the appropriate thickening correction without requiring manual intervention. The drawing command determination section and line width correction section work autonomously to identify and correct thin lines, eliminating the need for manual line-by-line adjustment.
3Adaptability or versatility
If existing solutions only process line drawing commands, then the device complexity is kept simple, but the adaptability is reduced because fill figure commands are not handled
Solution Approach 1:
The patent applies universality by making the image generation device capable of handling multiple types of drawing commands (both line drawing commands and fill figure commands) through a unified processing approach. The drawing command determination section identifies thin lines regardless of whether they are created by line drawing commands or fill figure commands, and the line width correction section applies thickening uniformly to both types, making the device versatile in handling different drawing methodologies.

AI summary
A thickening process is applied to a thin line fill figure that is not a line drawing command, and thereby output with an improved reproducibility is performed. An image processing apparatus includes: a drawing command determination section that determines whether a drawing command is a fill figure that forms a thin line; and a line width correction section that performs line width correction process of a drawing command determined to be a fill figure that forms a thin line.
