Claim:
1. A method for operating a TOF camera system which is operable with at least three modulation frequencies, the method comprising: a) implementation of a plurality of phase measurement cycles with different modulation frequencies; b) determination of a phase shift of an emitted and received signal for different modulation frequencies in each phase measurement cycle of the plurality of phase measurement cycles; c) implementation of a plurality of distance measurement cycles; d) determination of a distance value based on the phase shifts determined according to step b) in two subsequent phase measurement cycles in each distance measurement cycle of the plurality of distance measurement cycles; e) determination of a distance deviation between distance values according to step d) of successive distance measurement cycles; and f) output of a distance value according to step d) as a valid distance value if the distance deviation according to step e) falls within a tolerance limit.
