What Is a Color Sensor?
A color sensor is a sensor that can determine the color of an object and is a type of photoelectric sensor (a sensor that irradiates light onto an object to obtain information about that object). It determines the color of an object based on the degree to which it reflects or absorbs the three colors red, blue, and green.
Color sensors have the following advantages over single-wavelength photoelectric sensors.
- Color sensors can stably distinguish color combinations that are difficult to distinguish.
- Since it detects the ratio of red, blue, and green light received, it is not significantly affected by changes in the distance from the object.
Applications of Color Sensors
Color sensors are used in a variety of applications where colors need to be detected.
One example is the adjustment of display images. The color sensor analyzes the ambient light hitting the display and corrects the colors and other aspects of the display according to the results of the analysis. This technology is used to correct display images on LCD TVs, smartphones, tablets, and other devices. Similar technology is also used to adjust the color of LED lighting.
In addition, color sensors are also used for color control of products in factories, color identification of metals, and detection of register marks.
Principle of Color Sensors
Color sensors determine the color of an object by shining red, blue, and green light on the object and detecting which color (wavelength) of light is absorbed and how much of it is absorbed.
For example, when red, blue, and green light hits a red object such as an apple, only red light is reflected, while blue and green light is absorbed. As a result, only the reflected red light reaches our eyes, making the apple appear red. When the light of these three colors hits a white object, all light is reflected. So the object appears white to us because all the reflected light reaches our eyes.
Thus, the color of an object is determined by which color light is reflected and to what extent. It is the color sensor that detects this not with the human eye but as a device.
Inside a color, a sensor is a light emitter and a light receiver that detects light reflected from an object. Color is determined by the ratio of red, blue, and green detected by the light-receiving part. For example, if the light-reception ratio is red: blue: green = 1:1:1, the object color is white; if the ratio is 1:0:0, the object color is red, and so on.
