AR Color Tone Adjustment Using Virtual Marker Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printed matters often exhibit different color tones than intended due to varying installation environments, requiring repeated adjustments and printings to match the desired color tone, which is time-consuming and inefficient.
Innovation Solution
A print system that includes an image forming apparatus and a display using augmented reality, where a marker is printed and detected in the real environment, allowing for the calculation of differential color information to adjust the color tone of a virtual object displayed on the display, and subsequently adjusting the print adjustment value for the image forming apparatus to match the desired color tone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color tone adjustment is performed by repeatedly printing and confirming in the installation place, then the color tone matching the environment can be achieved, but the time required to obtain the desired printed matter increases
Solution Approach 1:
The patent uses a camera to capture an image of the marker in the installation environment and creates a virtual copy of the printed matter displayed on a display device. This virtual copy allows users to simulate and evaluate color tone appearance without physically printing multiple test samples, thereby reducing time while maintaining color tone accuracy
Solution Approach 2:
The system performs preliminary color tone simulation in a virtual environment before actual printing. By calculating differential color information between the captured marker image and reference data, and applying corrections to the virtual display, the system prepares the optimal color tone settings in advance, avoiding repeated trial printings
2Manufacturing precision
If the printed matter is output after adjusting the color tone, then the color tone can be optimized, but the printed matter may still not be seen in the intended way requiring further repetition
Solution Approach 1:
The system captures images of the marker in the actual installation environment using a camera, calculates differential color information between the captured image and reference data, and uses this feedback to automatically adjust and correct the color tone of the virtual displayed object. This closed-loop feedback mechanism ensures accurate color tone reproduction without repeated manual adjustments
Solution Approach 2:
The patent replaces the mechanical process of repeatedly printing physical test samples with an electronic/virtual system. The display device shows a virtual object that simulates how the printed matter will appear, allowing visual evaluation and adjustment without physical manipulation of printed materials

AI summary
A display includes a display unit, an image sensor that takes an image of a predetermined area and outputs the taken image, and a hardware processor that detects the marker in the taken image, generates differential color information between color data of the marker in the taken image and color data of the marker in the print image data, displays a virtual object which reproduces the print image data in the display unit, sets an object adjustment value for adjusting a color tone of the virtual object displayed on the display unit based on the differential color information, and calculates a print adjustment value for adjusting a color tone reproduced by the image forming apparatus based on the object adjustment value.
