1. A projector and illumination module configured for scene illumination and pattern projection, wherein the projector and illumination module comprises at least one array of a plurality of individual emitters and at least one optical system, wherein each of the individual emitters is configured for generating at least one illumination light beam, wherein the at least one optical system comprises at least one array of a plurality of transfer devices, wherein the at least one array of the plurality of transfer devices comprises at least one transfer device for each of the individual emitters, wherein the at least one array of the plurality of transfer devices further comprises at least two groups of transfer devices, wherein the transfer devices of the two groups differ in at least one property, wherein the transfer devices of one of the groups are configured for generating collimated light beams in response to illumination light beams impinging on said transfer devices, wherein the transfer devices of the other group are configured for generating diverging light beams in response to illumination light beams impinging on said transfer devices; wherein brightness of the diverging light beams and the collimated light beams are individually controllable, wherein emission power of the individual emitters associated with the same group of transfer devices is controllable and adjustable separately.
