Abstract: A method for operating a camera system for detecting codings, in which positions of contour points of the codings are determined in relation to edges of a search zone of the camera system, wherein a reading reliability of the search zone is determined from a distance of the contour points from the edges of the search zone.

Abstract: A 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 (?i) 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 (?n, ?n+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 (?d) 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 (?d) is within a tolerance limit (?dtol) is provided.

Abstract: A light propagation time camera system and a method for operating such a system, in which—in a distance measurement a first range-related variable is ascertained using a phase shift in an emitted and received signal for a first modulation frequency,—and in a control measurement a second range-related variable is ascertained, wherein the control measurement is performed at a second modulation frequency, which differs from the first modulation frequency, and the control measurement is performed with a smaller number of phases than the distance measurement is provided.
