Image scanning and displaying system for eliminating color difference

Abstract

An image scanning and displaying system for eliminating color differences is revealed. The system includes an image scanner and a display screen with a second emission spectrum. The image scanner consists of an optoelectronic image capturing and forming system, a plurality of first light sources disposed around the optoelectronic image capturing and forming system and a control module. The first light sources have a first emission spectrum which is a white light composed of a plurality of wavebands with different peak wavelengths. The control module controls the optoelectronic image capturing and forming system to take monochrome images in different colors in time sequence. The second emission spectrum has the same characteristics as the first emission spectrum.

Description

BACKGROUND OF THE INVENTION1. Technical Field[0001]The present invention relates to an image scanning and displaying system for eliminating color differences, especially to an image scanning and displaying system for eliminating color differences occurred during image scanning by electronic devices, image display by display screens and lighting provided for replicating teeth or other objects.2. Description of Related Art[0002]The era of information has arrived. The traditional manual operations are replaced by applications of information technology. For example, each step during the creation of denture models and the following production processes needs professional techniques of dentists and dental technicians. As to sampling and color comparison in clothing industry, these also take labors and some expert's experience. Moreover, the shoes can be designed in America, sampled in Asia and then sent back to American for confirmation. All these manual operations and sample confirmation...

AI Technical Summary

Benefits of technology

The patent aims to solve issues with color variations between an image scanner and a display screen in the dental industry. This technology can improve the accuracy of dental molds and samples, reduce timeliness and cost associated with long-distance delivery, and enable cross-border production and intelligent fabrication flow.

Problems solved by technology

As to sampling and color comparison in clothing industry, these also take labors and some expert's experience.

All these manual operations and sample confirmation processes have limits in distance, time and efficiency.

During these processes, not only the denture model is shipped long-distance or cross-country, making dentures also requires intense labor work for each step including creating dental models, color matching, carving and painting.

Thereby the denture fabrication is difficult to move to mass production.

Once the spectrum of the light sources in image-capturing environments and the spectrum of the display screen are not consistent, this would cause severe color differences.

At the moment, the color difference problem also occurs if the spectrum of ambient light for the workbench is not consistent with the spectrum of the display screen used for showing the dental mold images.

A little color difference among different devices used during denture fabrication results in severe color distortion in each step of the fabrication process.

These are the biggest challenges in long-distance production, cross-country production, informatization, automated production and intelligent production of the dentures.
