Color Judging Apparatus Reference Pixel Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional color judging methods are inefficient due to the need to process each pixel individually, leading to prolonged processing times, especially with increasing pixel densities in modern display technologies and limited processing capabilities in devices like mobile phones.
Innovation Solution
A color judging apparatus that designates certain pixels as reference pixels and shared pixels based on pixel values, where shared pixels have the same color difference values as the reference pixels, allowing for reduced processing by using the color judgment result of the reference pixel for shared pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color judgment is performed for all pixels individually, then measurement precision is improved, but processing time increases significantly
Solution Approach 1:
The patent merges the color judgment results of reference pixels and shared pixels by establishing that shared pixels inherit the color judgment result from their corresponding reference pixel. This combining approach allows the system to treat multiple pixels as a group rather than processing each individually, thereby reducing processing time while maintaining color judgment accuracy for all pixels in the image.
Solution Approach 2:
The patent performs color judgment preliminarily only for reference pixels before determining the results for shared pixels. By conducting the actual color measurement action in advance for a subset of pixels (reference pixels) and then propagating these results to shared pixels, the system achieves efficient processing without sacrificing the precision that would result from judging all pixels individually.
2Measurement precision
If color judgment is performed for all pixels, then color accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the pixel population into two distinct categories: reference pixels and shared pixels. This segmentation allows the processing system to handle only a subset of pixels (reference pixels) through full color judgment, while the remaining shared pixels receive their color judgment results through inheritance. This division significantly reduces processing complexity while preserving color accuracy for the entire image.
Solution Approach 2:
The patent makes the color judgment result of a reference pixel universally applicable to multiple pixels (both the reference pixel itself and its associated shared pixels). Instead of creating separate judgment processes for each pixel, the system establishes that one color judgment result can serve multiple purposes, thereby reducing device complexity and processing overhead.
3Reliability
If all pixels are processed individually, then processing completeness is improved, but productivity decreases
Solution Approach 1:
The patent creates a copy relationship where the color judgment result from a reference pixel is copied to its corresponding shared pixels. This copying mechanism ensures that all pixels receive a color judgment result (maintaining processing completeness) without requiring individual processing of each pixel (improving productivity). The shared pixels effectively receive a copy of the reference pixel's judgment result, achieving both completeness and efficiency.

AI summary
With a pixel included in image data as a reference pixel, a pixel that shares the same pixel value as the reference pixel or a pixel similar to the reference pixel is judged as a shared pixel, and for the pixel judged as the shared pixel, color of the reference pixel is regarded as a color judgment result of the shared pixel, thus making it possible to reduce color calculation processing for the shared pixel. This makes it possible to provide a color judging apparatus operating at higher speed and the like. Thereby, it is possible to provide the color judging apparatus operable at high speed and the like by reducing the number of times of the color calculation processing executed for an input image.
