MULTI-ILLUMINATION WHITE BALANCE CIRCUIT WITH THUMBNAIL IMAGE PROCESSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240334073 titled 'MULTI-ILLUMINATION WHITE BALANCE CIRCUIT WITH THUMBNAIL IMAGE PROCESSING
Simplified Explanation: The patent application describes an image processing circuit for multi-illumination white balance with thumbnail processing. This circuit determines initial weights for a source pixel in a thumbnail image based on component values for multiple color channels. It then calculates weights for the source pixel in a weight map for the thumbnail image, representing intensity levels of different chrominance classes. These weights are applied to the color channels of the source pixel to generate color component values for a target pixel in a target thumbnail image.
- The image processing circuit determines initial weights for a source pixel in a thumbnail image based on component values for multiple color channels.
- It calculates weights for the source pixel in a weight map for the thumbnail image, representing intensity levels of different chrominance classes.
- These weights are applied to the color channels of the source pixel to generate color component values for a target pixel in a target thumbnail image.
Potential Applications: This technology can be used in digital cameras, smartphones, and other devices that require white balance adjustments for images. It can improve the quality of images by ensuring accurate color representation across different lighting conditions.
Problems Solved: This technology addresses the challenge of achieving accurate white balance in images captured under various illumination conditions. It helps to maintain consistent color accuracy and quality in photos taken with different light sources.
Benefits: - Improved color accuracy in images - Consistent white balance across different lighting conditions - Enhanced image quality in thumbnails and full-size images
Commercial Applications: Title: Multi-Illumination White Balance Circuit for Image Processing This technology can be commercially applied in digital cameras, smartphones, and other imaging devices to enhance the quality of photos taken in different lighting environments. It can be marketed as a feature that ensures accurate color representation and white balance adjustments for professional-looking images.

Original Abstract Submitted
an image processing circuit for multi-illumination white balance with thumbnail processing. the image processing circuit determines a set of initial weights for a source pixel in a thumbnail image by determining component values for multiple color channels of the source pixel. the image processing circuit determines a set of weights for the source pixel in a weight map for the thumbnail image. each weight in the set of weights is determined based on corresponding initial weights from the set of initial weights. each weight in the set of weights represents an intensity level of a respective chrominance class of multiple chrominance classes for the source pixel. the image processing circuit applies the set of weights to values of the color channels of the source pixel to generate color component values of the color channels of a target pixel in a target thumbnail image.
