Color Sampler Blending Pixels for Accurate Shade Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAD applications rely on point sampling for color selection, which is inefficient and often results in selecting a color that is 'close' to the desired shade, as they cannot accurately capture the general impression of a region, leading to trial-and-error methods and inability to select colors that do not exist as a single pixel.
Innovation Solution
A method that allows users to blend colors by selecting pixels using a mouse cursor, where each selected pixel is incrementally blended into the current color at a constant rate, enabling gradual mixing of colors similar to painting, using a constant blending factor to achieve the desired color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If point sampling is used to select color from a single pixel, then the color selection process is simple, but the accuracy of capturing the desired color shade is poor
Solution Approach 1:
The patent combines multiple pixel color values into a single blended color representation. Instead of selecting from individual pixels, the system merges colors from multiple pixels in the vicinity, allowing users to capture the general impression of a region rather than being constrained to exact pixel matches.
Solution Approach 2:
The patent introduces an intermediary blending process between the raw pixel data and the final color selection. This intermediary step processes multiple pixel values through blending algorithms to produce a representative color that accurately reflects the desired shade, resolving the contradiction between simplicity and accuracy.
2Measurement precision
If multiple colors are selected through trial and error, then the desired color can be found, but the time required for color selection increases
Solution Approach 1:
The patent performs preliminary color blending calculations before the user makes a final selection. By pre-processing multiple pixel values and blending them according to the user's intent, the system reduces the need for repeated trial-and-error selections, significantly cutting down color selection time while maintaining high accuracy.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously refines the blended color based on user interaction and selection patterns. This feedback loop allows the system to learn from user preferences and automatically adjust blending parameters, reducing the time needed to achieve the desired color accuracy.
3Adaptability or versatility
If a small pixel matrix (3×3 or 5×5) is used for color selection, then the selection process is simpler than point sampling, but the ability to capture the general impression of a region is still limited
Solution Approach 1:
The patent implements a dynamic pixel sampling approach where the system adaptively determines which pixels to include in the blending calculation based on the user's selection behavior and the visual characteristics of the image. This dynamic adaptation allows the system to capture the general impression of regions of varying sizes and shapes, improving both versatility and accuracy compared to fixed matrix approaches.

AI summary
A method for selecting a desired color from a screen display using a color selection tool that may appear as an eyedropper. Rather than independently choosing pixels or a matrix of pixels, the user blends a color by selecting pixels using a mouse cursor. In response, the color of each selected pixel is incrementally blended into the current color at a constant rate. That is, each selected pixel is blended with the current color according to a constant blending factor. In this manner, the current color changes at a constant rate with the contribution of each successive pixel. This approach allows the user to gradually blend colors from the screen display, much as a painter would gradually mix colors on a palette.
