BRIGHTNESS BASED CHROMATICITY WEIGHTING FOR IMPROVED ILLUMINANT COLOR ESTIMATION FOR AUTO WHITE BALANCING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240196104 titled 'BRIGHTNESS BASED CHROMATICITY WEIGHTING FOR IMPROVED ILLUMINANT COLOR ESTIMATION FOR AUTO WHITE BALANCING
Simplified Explanation: The patent application presents apparatuses, systems, and techniques for white balancing an image using a chromaticity-based weighting function to minimize the impact of large colored portions or objects within the image when estimating an illuminant color.
- **Chromaticity-based weighting function**: Determines the weighting based on estimated scene brightness to exclude or minimize the impact of large colored portions.
- **White balancing**: Adjusts the colors in an image to accurately represent the true colors under different lighting conditions.
Potential Applications: This technology can be applied in various fields such as photography, image processing, computer vision, and video production to enhance color accuracy and quality in images and videos.
Problems Solved: This technology addresses the challenge of accurately white balancing images with large colored portions or objects that can distort the true colors in the image.
Benefits: - Improved color accuracy in images and videos - Enhanced visual quality and realism - Simplified white balancing process for photographers and videographers
Commercial Applications: The technology can be utilized in digital cameras, smartphones, video cameras, surveillance systems, and other imaging devices to improve color reproduction and overall image quality, catering to professionals and enthusiasts in the photography and videography industry.
Prior Art: Prior art related to this technology may include existing methods for white balancing images and techniques for color correction in digital imaging.
Frequently Updated Research: Stay updated on advancements in color science, image processing algorithms, and computer vision technologies to enhance the performance and capabilities of white balancing techniques.
Questions about White Balancing Technology: 1. How does the chromaticity-based weighting function improve the accuracy of white balancing in images? 2. What are the potential limitations of using this technology in different lighting conditions?
Original Abstract Submitted
apparatuses, systems, and techniques for white balancing an image are presented. in at least one embodiment, a chromaticity-based weighting function is determined based at least on an estimated scene brightness of the image and applied to exclude or minimize the impact of large colored portions or objects within an image when estimating an illuminant color.
