Description
Technical Field
The invention relates to a high-precision integrated color sensor.
Background
The color sensor has high detection reliability for similar colors and hues. It is color detection by measuring the reflectance of the three primary colors that make up the color of the object. Since this color detection method is extremely precise, the sensor can accurately distinguish extremely similar colors, even different hues of the same color.
The general sensor has three light sources of red, green and blue. The three lights are reflected by the target object after being emitted through the same lens. The amount of light that is reflected or absorbed depends on the object color.
The sensor has two measurement modes. One is to analyze the ratio of red, green and blue light. Since the detection distance can only cause a change in light intensity regardless of a change in the detection distance, and the ratio of the three colors of light does not change, detection is possible even in the case where the object has mechanical vibration.
The second mode is to use the intensity of the reflected light of the three primary colors of red, green and blue to achieve the detection purpose. With this mode, detection of a minute color discrimination can be realized, but the sensor is affected by the mechanical position of the target. Whichever mode is used, most sensors have a guiding function, making them very easy to set. Most of these sensors have some form of built-in map and threshold that can be used to determine operating characteristics.
