Method for generating image effects in the interior of a vehicle and/or outside the vehicle, comprising at least the steps of: - generating at least one first optical reference wave field; - directing the first optical reference wave field in the direction of at least one optical image storage device; - radiating the first optical reference wave field into at least one irradiation surface of the optical image storage device; - transforming the first optical reference wave field into at least one first image wave field by way of at least one holographic layer or diffractive optical layer of the optical image storage device; and - outcoupling the first image wave field from the holographic layer or diffractive optical layer at an outcoupling side; wherein between a first irradiation surface, via which at least the first optical reference wave field is radiated in, and the outcoupling side, via which at least the first image wave field is outcoupled, there is a first angular offset, the optical reference wave field is guided in the optical image storage device by reflection at inner interfaces (34; 36) and passes at least sectionally proportionally through an inner interface of the optical image storage device which faces the holographic layer or diffractive optical layer and which is at least sectionally proportionally light-transmissive, wherein at least one first optical reference wave field and one second optical reference wave field are generated and the first optical reference wave field is radiated into the optical image storage device at the first irradiation surface and the second optical reference wave field is radiated into the optical image storage device at a second irradiation surface, and the first and the second optical reference wave field are transformed simultaneously or in a time-shifted manner into the first image wave field or into different image wave fields, and the first image wave field or the different image wave fields is/are outcoupled at the outcoupling side serving as a common outcoupling side, and between the first irradiation surface and the outcoupling side there is the first angular offset and at least one second optical reference wave field is generated, which is radiated into at least one second irradiation surface, characterized in that the second irradiation surface and the outcoupling side serving as a common outcoupling side are oriented parallel to one another. - generating at least one first optical reference wave field; - directing the first optical reference wave field in the direction of at least one optical image storage device; - radiating the first optical reference wave field into at least one irradiation surface of the optical image storage device; - transforming the first optical reference wave field into at least one first image wave field by way of at least one holographic layer or diffractive optical layer of the optical image storage device; and - outcoupling the first image wave field from the holographic layer or diffractive optical layer at an outcoupling side; wherein between a first irradiation surface, via which at least the first optical reference wave field is radiated in, and the outcoupling side, via which at least the first image wave field is outcoupled, there is a first angular offset, the optical reference wave field is guided in the optical image storage device by reflection at inner interfaces (34; 36) and passes at least sectionally proportionally through an inner interface of the optical image storage device which faces the holographic layer or diffractive optical layer and which is at least sectionally proportionally light-transmissive, wherein at least one first optical reference wave field and one second optical reference wave field are generated and the first optical reference wave field is radiated into the optical image storage device at the first irradiation surface and the second optical reference wave field is radiated into the optical image storage device at a second irradiation surface, and the first and the second optical reference wave field are transformed simultaneously or in a time-shifted manner into the first image wave field or into different image wave fields, and the first image wave field or the different image wave fields is/are outcoupled at the outcoupling side serving as a common outcoupling side, and between the first irradiation surface and the outcoupling side there is the first angular offset and at least one second optical reference wave field is generated, which is radiated into at least one second irradiation surface, characterized in that the second irradiation surface and the outcoupling side serving as a common outcoupling side are oriented parallel to one another.
