Color detector, color identification device and method for identifing colors

Abstract

A color detector is prepared as fixing light source and sensor on shell, shining detection light of three basic color as red and green as well as blue on object to be detected by light source, using sensor to receive reflection lights generated separately by object to be detected as per three basic colors and generating electric signal corresponding to color of object to be detected according to light parameter of said reflection light. The color identification device and relevant color identifying method are also disclosed.

Description

technical field [0001] The invention relates to the field of color recognition, in particular to a color detector and a color recognition device using the color detector. The invention also provides a color recognition method using the color recognition device. Background technique [0002] Color recognition using electronics is a constantly evolving technology with ever-expanding fields of application. For example, it is convenient for the blind or color-blind patients to identify colors, and the color recognition function is set in the toy to increase education and fun. [0003] Most of the existing technologies use complementary metal oxide semiconductor sensors (CMOS SENSOR) to realize color recognition, which use integrated CMOS photocoupler devices to sense the reflection signal of the object to be measured under ordinary white light irradiation, and obtain electrical signals; and then obtain electrical signals based on the electrical signals The characteristics of e...

AI Technical Summary

Problems solved by technology

The disadvantages of this invention are: its analysis and calculation process is relatively complicated; the requirements for the device that generates white light source and the photodiode that receives red, green and blue reflected light are relatively high, the production is difficult and the cost is high

The cost of this patent is lower than that of the previous patent, but the light source received by the device is still an approximate white light source. Adding a concave lens to synthesize white light not only increases the cost and complexity of the device, but also increases the difficulty of production

This patent does not give a specific method for processing and identifying the received light source signal, but using white light as the light source must have higher requirements for the light source receiving element, otherwise the required recognition range and accuracy cannot be achieved
