Light transit time camera system and method for operating such a system which can be operated with at least three modulation frequencies, having the steps a) determining a phase shift (phii) of an emitted signal (Sp1) and a received signal (Sp2) for a modulation frequency (f1, f2, f3) in a phase-measuring cycle (PM1, PM2,...), b) carrying out a plurality of phase-measuring cycles (PM1, PM2,...), c) determining a distance value (dn,n+1) on the basis of the phase shifts (phin, phin+1) determined in two successive phase-measuring cycles (PMn, PMn+1), in a distance-measuring cycle (M1, M2,...), d) carrying out a plurality of distance-measuring cycles (M1, M2,...), e) determining a distance deviation (Deltad) between the distance values of successive distance-measuring cycles, f) outputting of a distance value (dn,n+1) as a valid distance value if the distance deviation (Deltad) is within a tolerance limit (Deltadtol). |
