Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing technologies face challenges in accurately correcting color artifacts and improving color accuracy in images captured by multi-camera systems, particularly in reducing inaccurate colorization and enhancing color representation across overlapping fields-of-view.
Innovation Solution
The implementation of an image signal processor that obtains input images from image sensors, applies color correction with desaturation control to minimize inaccurate colorization, and outputs a color-corrected image, utilizing techniques such as linear desaturation, linear interpolative desaturation, and adaptive desaturation control to adjust color components and reduce artifacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If color correction is applied to images from multi-camera systems, then color accuracy is improved, but inaccurate colorization artifacts are introduced
Solution Approach 1:
The image signal processor divides the image into multiple regions based on saturation levels, applying different processing strategies to different segments. High-saturation regions are processed differently from low-saturation regions, allowing color correction to be applied accurately while preventing artifact formation in problematic areas
Solution Approach 2:
The system dynamically adjusts color correction parameters based on local saturation characteristics. By changing saturation thresholds and correction intensity as parameters, the processor optimizes color accuracy in different regions while minimizing the introduction of colorization artifacts
2Object-generated harmful factors
If desaturation control is implemented, then inaccurate colorization is minimized, but processing complexity increases
Solution Approach 1:
The image signal processor performs preliminary saturation analysis and region classification before applying color correction. By pre-identifying high-saturation regions that are prone to artifacts, the system can apply targeted desaturation control only where needed, reducing overall processing complexity while maintaining effectiveness
Solution Approach 2:
Instead of applying desaturation control uniformly across the entire image, the system applies partial action only to specific regions where saturation causes problems. This selective approach minimizes processing complexity by avoiding unnecessary computations in regions where color correction is already accurate

AI summary
Image signal processing may include desaturation control, which may include adaptive desaturation control. Image signal processing with desaturation control may include obtaining, by an image signal processor, from an image sensor, an input image signal representing an input image, obtaining, by the image signal processor, color correction information for the input image, obtaining a color corrected image based on the input image using color correction with desaturation control such that inaccurate colorization of the color corrected image is minimized, and outputting the color corrected image.
