    Abstract: PURPOSE:To obtain a precise reflected light signal stably even when a frequency of lighting is low, and to improve a processing speed by integrating reflected light and disturbing light when light emitting elements are turned on and the disturbing light when turned off, and regarding a difference in an addition mean for every (n) times as the reflected light signal. CONSTITUTION:The light emitting elements 1-3 of R, G, and B are turned on impulsively in time series by lighting timing pulses alpha, beta, and gamma in the figure (a) from a microcomputer 6 through an LED driver 7. 5 is a photodetecting element and photodetects the reflected or disturbing light and amplifies it. A switching circuit 11 and a multiplexer 14 are switched by a signal from the microprocessor 6. Integrating circuits 12 and 13 are discharged by the signal from the microcomputer 6. The photodetection signals of the reflected light and disturbing light are integrated by the integrating circuit 12 as shown by the figure (b) matching with the lighting times of the light emitting elements 1-3, and pulses shown in the figure (c) are A/D- converted once the lighting ends; this is repeated (n) times. At the time of the disturbing light signal, pulses are integrated by the integrating circuit 13 as shown in the figure (d) when the light emitting elements are turned on, and pulses shown in the figure (e) are A/D-converted once the elements are turned off completely; this is also repeated (n) times. Then, a reflected light signal is obtained from a difference in addition means for (n) times.

    Abstract: PURPOSE:To improve the precision of a reflection signal and to speed up processing by turning on two of light emitting elements for three colors in combination successively and simultaneously. CONSTITUTION:When the light emitting elements 1-3 of R, G, and B are turned on, two of the elements are turned on in combination simultaneously and successively. Namely, the light emitting elements 1 and 2 of R and G are turned on n0 times simultaneously as shown by a' in the figure (a), the light emitting elements 2 and 3 of G and B are turned on n0 times simultaneously as shown by b', and then the light emitting elements 3 and 1 of B and R are turned on n0 times as c' simultaneously. The figure (b) shows A/D-conversion pulses when the elements are turned on and the figure (b) shows A/D-conversion pulses when turn off. Therefore, reflected light signals Rs, Gs and Bs are found by obtaining signals by the calculation formulae Rs+Gs, Gs+rs, and Bs+Rs.
