AI Technical Summary
Current image acquisition technologies struggle with white-balancing and color correction in mixed illumination conditions, leading to insufficient results and amplified color casts, especially when dealing with self-illuminated objects like screens and signs.
A method for image processing that identifies regions of interest (ROI) with different illuminations, determines specific correction parameters for these ROIs and the surrounding areas, and applies them to generate a final image with improved white-balancing and color correction.
This approach allows for accurate and efficient spatial white-balancing, reducing color casts and improving image quality by tailoring correction parameters to specific illumination conditions within the image.
