摘要

A distance-measuring apparatus and a distance-measuring method. The distance-measuring apparatus and the distance-measuring method include emitting pulsed light, receiving and photoelectrically converting the pulsed light emitted and reflected by an object into a plurality of electrical signals, sorting the electrical signals into a plurality of phase signals, storing data including the phase signals or a value that is based on the phase signals, determining whether or not a dynamic change is present in the object, based on the data of a current frame and at least one past frame, and calculating distance to the object using the data, according to a result of determination made by the determining. When determined that the dynamic change is not present, moving average calculations are performed on the data of at least two of the current frame and a plurality of frames including the at least one past frame.
