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.
