APPARATUS AND METHOD FOR PERFORMING COLOR TRANSFORMATION ON RAW SENSOR IMAGES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18110032 titled 'APPARATUS AND METHOD FOR PERFORMING COLOR TRANSFORMATION ON RAW SENSOR IMAGES

Simplified Explanation

The patent application describes a method for processing image data. Here is a simplified explanation of the abstract:

  • The method starts by obtaining a raw input image captured under a specific illumination.
  • A target illumination is obtained from user input.
  • An intermediate image is obtained from the raw input image, which captures colors under a reference illumination. This is done using a first color transform that maps the input illumination to the reference illumination based on an illumination dataset of raw sensor images captured under different illuminations.
  • Finally, an output image is obtained from the intermediate image, capturing colors under the target illumination. This is done using a second color transform that maps the reference illumination in the illumination dataset to the target illumination.

Potential applications of this technology:

  • Image processing and editing software
  • Photography and videography tools
  • Color correction and adjustment in various industries such as advertising, fashion, and graphic design

Problems solved by this technology:

  • Inconsistent color representation due to variations in illumination conditions
  • Difficulties in accurately capturing and reproducing colors under different lighting conditions

Benefits of this technology:

  • Improved color accuracy and consistency in image processing
  • Enhanced ability to adjust and manipulate colors in images
  • Increased flexibility in capturing and reproducing colors under different lighting conditions


Original Abstract Submitted

A method for processing image data may include: obtaining a raw input image that is captured under an input illumination; obtaining a target illumination from a user input; obtaining an intermediate image having colors captured under a reference illumination, from the raw input image, based on a first color transform that maps the input illumination to the reference illumination in an illumination dataset of raw sensor images that are captured under a plurality of different illuminations; and obtaining an output image having colors captured under the target illumination, from the intermediate image, based on a second color transform that maps the reference illumination in the illumination dataset to the target illumination.
