Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual color correction of images in retail environments is inefficient and inconsistent, especially when dealing with large volumes of inventory across various photo studios.
Innovation Solution
An automated two-step color correction process using a color checker image to generate color correction information, either as a color correction matrix or white-balance parameters, which are then applied to raw images to produce consistently colored images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual color correction techniques are used, then color accuracy can be adjusted, but processing speed and efficiency deteriorate significantly when dealing with large volumes of images
Solution Approach 1:
The patent replaces manual mechanical color correction processes with an automated computational system. A color correction matrix is generated from a color checker image and automatically applied to correct colors in product images, eliminating the need for manual adjustment while maintaining color accuracy and significantly increasing processing speed for large volumes of images
Solution Approach 2:
The patent uses a color checker image (a standardized reference object) as a copy or template to establish color correction parameters. This reference image is processed to generate a correction matrix that is then replicated and applied across multiple product images, ensuring consistent color accuracy without manual intervention for each image
2Manufacturing precision
If manual color correction is performed across multiple photo studios, then individual image quality can be maintained, but consistency and reliability of color standards deteriorate
Solution Approach 1:
The patent creates a universal color correction matrix that can be applied across multiple photo studios and different product images. This single correction matrix, derived from a standardized color checker, serves as a universal standard that ensures consistent color accuracy across all images processed, regardless of which studio captured them
Solution Approach 2:
The patent transforms color correction from a subjective manual process into an objective parameter-based system. By converting color correction into mathematical matrix operations with specific numerical parameters, the system ensures reliable and consistent color standards across different studios while maintaining high image quality
3Productivity
If automated color correction is implemented, then processing efficiency improves, but system complexity increases
Solution Approach 1:
The patent performs preliminary color correction by generating a correction matrix from a color checker image captured during the photo session. This preliminary action establishes the color parameters in advance, allowing rapid automated correction of all product images without requiring complex real-time processing algorithms for each image

AI summary
A color correction system comprises a correction information generator and an image processor. The correction information generator generates color correction information from a color correction image associated with a plurality of images. The image processor automatically processes the plurality of images based on the color correction information to generate a plurality of color-corrected images. In operation, images and a color correction image associated with the images are received. Next, color correction information is generated from the color correction image. For example, color correction information includes a color correction matrix or white balance parameters. Next, the images are automatically processed based on the color correction information thereby generating color-corrected images. The system automates color correction processing of studio images to provide highly scalable and reliable color correction. Significant quantities of studio images are consistently color-corrected based on processing of the color correction image.
