A distance-measurement device (10), wherein: for each frame period (TF), a control unit (CONT) alternatingly switches the chronological order of a first pulse-forwarding signal (S1) and a second pulse-forwarding signal (S2), and outputs the first and second pulse-forwarding signals (S1, S2); and a calculation unit (ART) calculates a distance (d) to an object (OJ) on the basis of the total charge amount (Q1, Q2) of the signal charges stored in a first charge storage region (FD1) and a second charge storage region (FD2), according to the first and second pulse-forwarding signals (S1, S2), the phase of which is identical in two chronologically consecutive frame periods (TF). |
