Solution Overview
Problem
Existing embroidery data creation apparatuses face issues with maintaining image clarity and detail when adjusting the size or tint of images, leading to blurred or unclear embroidery results due to changes in angle characteristic strength and thread density.
Innovation Solution
An embroidery data creation apparatus that includes an angle data creation device, color data creation device, angle information computing device, and image data scaling device, which computes and re-computes angle characteristics and strengths, and adjusts thread colors to maintain image clarity and detail during size and tint adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image data is expanded to increase the number of pixels, then the image clarity is improved, but the angle characteristic strength decreases and the embroidery result becomes blurred
Solution Approach 1:
The patent segments the image processing into two independent paths: one for color data and one for angle information. The angle information is extracted and stored separately before scaling, allowing it to be preserved without being affected by the blurring that occurs during image expansion. This segmentation enables the angle characteristics to maintain their precision even when the image is scaled up.
Solution Approach 2:
The patent performs the extraction and storage of angle information as a preliminary action before the image scaling operation. By computing and storing the angle characteristics in advance on the original image data, the system avoids the problem where angle characteristic strength is computed on already-blurred expanded images. This preliminary extraction ensures that sharp angle information is available for the final embroidery data creation.
2Area of stationary object
If image data is reduced to decrease the number of pixels, then the embroidery area is reduced, but the details of the reduced image are collapsed
Solution Approach 1:
The patent separates color data processing from angle information processing. The angle information is extracted and stored independently before reduction, so it retains its original precision even when the color image is scaled down. This allows the embroidery area to be reduced while preserving the angular details and characteristics that would otherwise be collapsed.
Solution Approach 2:
The patent performs angle information extraction as a preliminary action before image reduction. By computing angle characteristics on the original high-detail image data and storing them separately, the system preserves fine angular details even when the final embroidery area is reduced. The angle information acts as a reference that maintains detail integrity during the reduction process.
3Illumination intensity
If image data is made brighter to increase luminosity, then the image tint is adjusted, but the angle characteristic strength decreases and the embroidery result becomes blurred
Solution Approach 1:
The patent divides the image data processing into separate channels: color/luminosity data and angle information data. By extracting angle information independently before luminosity adjustment, the system preserves angle characteristic strength even when the image is made brighter. The angle data remains unaffected by the luminosity changes applied to the color data.
Solution Approach 2:
The patent performs angle information extraction as a preliminary action before applying luminosity adjustment. This ensures that angle characteristics are captured when the image has its original contrast and luminosity levels, maintaining strong angle characteristics. The subsequent brightness adjustment is applied only to the color data, leaving the pre-extracted angle information intact.
Data Source
AI summary
To provide an embroidery data creation apparatus, an embroidery data creation program, and a recording medium that records the embroidery data creation program, which create embroidery data for embroidery that is clear and sharp even when the tint or output size of an image is changed. The number of pixels necessary to create embroidery data is determined from thread density, size of the embroidery, and copied color data. Initial angle information is created from angle data and the angle information having necessary pixel configuration is re-computed from the initial angle information. Then, line segment data is created from the re-computed angle information, color data is created from the size adjusted color data and the line segment data, and the embroidery data is created from the line segment data and the color data.
