1. A camera arrangement, comprising: one illumination device for illuminating a plurality of fields of view, at least one object to be detected respectively lying in each of the fields of view; a time-of-flight (TOF) sensor; and a common objective lens arranged between the objects and the TOF sensor, wherein the one illumination device, the common objective lens, and the TOF sensor are arranged with respect to one another, and with respect to the fields of view and the objects lying therein, in such a way that images of the objects can be imaged simultaneously or in chronological succession on the one TOF sensor, and wherein images of the at least one object respectively lying in each of the plurality of fields of view are imagable separately in different regions on the one TOF sensor, the common objective lens is configured to focus a first beam path of a first field of view on a first region on the one TOF sensor, and the common objective lens is configured to focus a second beam path of a second field of view on a second region on the one TOF sensor which does not overlap the first field of view; and wherein the illumination device is arranged outside the first or second beam paths between the object and the one TOF sensor, and a control unit is configured to measure a round trip time of the light from the illumination device to the object and, based on the measured round trip time of the light a distance of the object to the camera arrangement; wherein a head of a driver and/or a head of a passenger, gestures, expressions, eye positions, viewing directions, seat positions, head positions and/or anthropometric features of the driver and/or passenger is or are monitored inside a vehicle; and wherein the camera arrangement is configured such that background light is at least predominantly suppressed and only light coming from the one illumination device and reflected by the at least one object is detected.
