ENCLOSED TYPE COLOR SENSOR

摘要

PURPOSE: An enclosed type color sensor having high accuracy is provided to determine a color of a subject without influence on the amount of outer light by blocking the incident of the external light and using a standard light source. CONSTITUTION: A color sensor(240) outputs a code by sensing light which is reflected from a subject. An external light block layer(220) blocks the external light between the color sensor and the subject. A standard light source(230) irradiates light to the subject. A control unit(250) outputs the voice. The standard light source is composed of a blue LED which outputs blue light and a red LED which outputs red light.
