Claim 11:
12. A camera apparatus for generating spatially representative image data of an environment, comprising:
a carrier medium providing a light guide and having at least two coupling regions and a decoupling region, each coupling region having a coupling deflection structure, formed by one of a surface holographic grating and a volume holographic grating, to couple light, incident thereon separately from the environment into the carrier medium, the carrier medium configured to transmit the light coupled in via the at least two coupling regions by internal reflection to the decoupling region, and the decoupling region having a decoupling deflection structure configured to decouple the light, incident on the decoupling region, out of the carrier medium;
an image acquisition device abutting the decoupling region, configured to acquire the light decoupled from the carrier medium and to generate therefrom respective image data, respectively correlated with the light of the environment incident on each of the at least two coupling regions and to generate the spatially representative image data from the respective image data; and
a separating device configured to separate the light incident on the at least two coupling regions, so that the image acquisition device separately acquires the light incident on the at least two coupling regions,
wherein the image acquisition device includes an image sensor configured to receive the light incident on the at least two coupling regions as one of superimposed and in succession,
wherein the separating device is configured to separate the light incident on the at least two coupling regions chronologically,
wherein the at least two coupling regions are switchable,
wherein the separating device separately switches a deflection characteristic of the at least two coupling regions, and
wherein the separating device includes a switchable darkening layer switchable chronologically in dependence on a switching state.
