1. A distance measuring, device which intermittently emits light to a measured object and measures a distance to the measured object based on time from the emission of the light until scattered light of the light scattered on the measured object is detected, the device comprising:
an optical detector to detect the scattered light; and a measurer having a sampler to sample a signal corresponding to an output signal of the optical detector every time when the light is emitted at a plurality of sampling time points, the plurality of sampling time points being segmented into at least first and second segments, and a storage to store a value obtained by accumulating sampling values at each sampling time point, to measure the distance based on a plurality of first accumulation values at the sampling time points in the first segment and initialize the first accumulation value every time when a first ending condition is satisfied, and to measure the distance based on a plurality of second accumulation values at the sampling time points in the second distance segment and initialize the second accumulation value every time when a second ending condition is satisfied. |
