Image Processing Method for Smoothing Color Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies suffer from image color stratification due to drastic variability in color gradation values, leading to poor display effects.
Innovation Solution
An image processing method that identifies content-associated sub-pixels, increases their color gradation value digits from 6 bits to 8 bits by adding digits and assigning preset values, thereby reducing the variation between adjacent sub-pixels' color gradation values and smoothing color transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color gradation values are increased to reduce color stratification, then display quality improves, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies different processing strategies to different regions of the image based on local characteristics. Content-associated sub-pixels (those representing actual image content) receive bit extension processing to increase color gradation precision, while background sub-pixels use simpler interpolation. This localized approach improves color stratification in important regions without uniformly increasing processing complexity across the entire image.
Solution Approach 2:
The patent segments the image processing into distinct stages: identifying content-associated sub-pixels, obtaining initial color gradation values, extending bits for selected sub-pixels, and interpolating remaining values. This segmentation allows complex color processing to be applied selectively rather than uniformly, reducing overall processing complexity while maintaining color precision where needed.
2Measurement precision
If bit extension is applied to all sub-pixels, then color gradation precision improves, but processing time and computational load increase
Solution Approach 1:
The patent applies bit extension only to content-associated sub-pixels rather than all sub-pixels in the image. By identifying and processing only the necessary portion (content-associated sub-pixels that contribute to actual image information), the patent achieves sufficient color gradation precision for display while avoiding the excessive processing time and computational load that would result from applying the same operation to every sub-pixel including background areas.
3Stability of the object's composition
If color gradation values are smoothed across adjacent sub-pixels, then color transition naturalness improves, but color accuracy in specific regions may be reduced
Solution Approach 1:
The patent applies different processing methods to different regions: content-associated sub-pixels maintain their original color gradation values (preserving accuracy), while background sub-pixels use interpolation to achieve smooth transitions. This localized differentiation allows the system to preserve color accuracy in important content regions while achieving natural color transitions in background areas, resolving the contradiction between smoothness and accuracy.

AI summary
The present disclosure relates to an image processing method, an image processing device and an electronic device. The method comprises: choosing content-associated sub pixels in an image to be processed; obtaining an initial color gradation value of each of the content-associated sub pixels in the image to be processed; adding at least one digit at an end of the initial color gradation value, and assigning a preset value to each added digit, so as to obtain a processed color gradation value; and replacing the initial color gradation value with the processed color gradation value. With the technical solution of the present disclosure, the image display effect may be optimized, and thus the color transition in the image is more smooth.
