(B) color filters, from the reflected object light decomposed into three colors. After the color signal op amps after enlarging processing, processing logic depending on the combination of the color obtained after the actual output. Figure 7-23 is a color sensor s amplification circuit, the X, Y, Z output colors. The practical application of color vision based on the circuit.
