ABSTRACT:
A distance measuring equipment wherein two images of an object are received on photosensor arrays each, two image data rows indicating a luminous intensity distribution in the object are compared with each other, and a distance to the object is measured from a mutual shift rate of both the signal rows which is required for bringing both the signal rows into coincidence at high correlation. A presence of the shift rate whereat the both image data rows indicate a high correlation is detected when it is present plurally, a part of the plural shift rate including a shift rate corresponding to the highest correlation is stored and taken.
