Traditional color recognition systems need white balance adjustment which introduces human error

resulting in poor distinguish accuracy.A kind of improved color recognition program is introduced.TCS3200D color sensor converts the color signals to digital signal and sent directly to the AT89C52 microcontroller processing with simple hardware circuit.An improved software algorithm process is designed on the basis of the basic software algorithms to avoid human error introduced by the white balance adjustment

effectively improves the recognition precision.Experimental result shows that the system has fast identification speed of different colors

high precision

and can be widely used in a variety of color composition analysis and the identification industry.
