ABSTRACT:
Disclosed is a distance measuring apparatus for measuring the distance to an object on the basis of reflected light obtained as a result of projecting light onto an object, in which different reliability or contrast discrimination values are set in active and passive distance measurements. When the distance to the object is calculated by performing a correlation calculation on the basis of two received-light images obtained by an active or passive distance measurement, the reliability of the calculated distance and contrast values of the two received-light images are discriminated using the discrimination value.
