Abstract

In order to enable high image acquisition rate with simultaneous low energy consumption of a camera 1, a camera (1), in particular a 3D time-of-flight camera, is provided, comprising an illumination unit (2) which emits light pulses during an illumination phase (Bp), an image sensor (3) which generates images from the light pulses reflected by an object, a switching controller (4) which controls current to the illumination unit (2), the switching controller (4) being operable in a continuous and a discontinuous mode (CCM; DCM), and a control unit (5) which is designed to activate and deactivate the continuous mode (CCM) of the switching controller (4) as a function of the illumination phase (Bp) of the illumination unit (2).
