COLOR ADJUSTMENT APPARATUS USED FOR COLOR MATCHING BETWEEN IMAGE CAPTURING APPARATUSES, COLOR ADJUSTMENT METHOD, AND STORAGE MEDIUM STORING COLOR ADJUSTMENT PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324100 titled 'COLOR ADJUSTMENT APPARATUS USED FOR COLOR MATCHING BETWEEN IMAGE CAPTURING APPARATUSES, COLOR ADJUSTMENT METHOD, AND STORAGE MEDIUM STORING COLOR ADJUSTMENT PROGRAM

Simplified Explanation

The color adjustment apparatus described in this patent application is designed to display color matching accuracy in a visually understandable way. Here are the key points:

  • The apparatus includes a memory and a processor that execute instructions.
  • It captures a color chart with a reference camera to obtain a first captured image.
  • It captures the same color chart with a target camera to obtain a second captured image.
  • It obtains correction information for color matching.
  • It applies the correction information to the second captured image to generate a third captured image.
  • It outputs color difference signals of the first captured image and the third captured image.
  • It generates a first image based on color difference signals in areas corresponding to the patches on the color chart in the first captured image.
  • It generates a second image based on color difference signals in areas corresponding to the patches on the color chart in the third captured image.

Potential applications of this technology:

  • Color calibration in photography and video production.
  • Quality control in printing and manufacturing industries.
  • Color correction in digital image processing.

Problems solved by this technology:

  • Ensures accurate color matching between different cameras.
  • Provides a visually intelligible representation of color differences.
  • Simplifies the process of color adjustment and calibration.

Benefits of this technology:

  • Improves the accuracy and consistency of color reproduction.
  • Reduces the time and effort required for color adjustment.
  • Enables better quality control and color management in various industries.


Original Abstract Submitted

A color adjustment apparatus capable of displaying color matching accuracy in a visually intelligible manner. The apparatus includes a memory storing instructions, and a processor executing the instructions to obtain a first captured image by capturing a color chart including patches with a reference camera, obtain a second captured image by capturing the color chart with a target camera, obtain correction information for color matching, generate a third captured image by applying the correction information to the second captured image, output color difference signals of the first captured image and color difference signals of the third captured image, generate a first image based on color difference signals in areas corresponding to the patches among the color difference signals of the first captured image, and generate a second image based on color difference signals in areas corresponding to the patches among the color difference signals of the third captured image.
