Zusammenfassung:An optical sensing device includes a first sensor, a second sensor, a third sensor and a fourth sensor for sensing light to generate a first sensing signal, a second sensing signal, a third sensing signal and a fourth sensing signal, respectively. A spectrum of a coating of the first sensor includes a first peak of a X spectrum. A spectrum of a coating of the second sensor includes a second peak of the X spectrum. A spectrum of a coating of the third sensor includes a Y spectrum. A spectrum of a coating of the fourth sensor includes a Z spectrum. The first sensing signal and the second sensing signal are used to determine a X output value. The third sensing signal and the fourth sensing signal are used to determine a Y output value and a Z output value, respectively.
