摘要： An electro-optical distance measuring device having a photodetection unit comprising a plurality of pixels arranged in a predetermined arrangement is disclosed. A signal processing unit has a storage unit for storing the detection result in correspondence with each of the pixels, wherein the signal processing control unit sequentially changes a position of the division for every cycle wave at which the photodetection amount is detected and continues detections until a detected range becomes at least one cycle or more. The arithmetic processing unit calculates a waveform for at least one cycle stored in the storage unit for each pixel, obtains a phase difference of the waveform with respect to the irradiated distance measuring light, and calculates the distance based on the phase difference.
