An integral image device (1) comprises an array (20) of focusing micro-lenses (22), optionally a reflecting layer (40) and an image fragment plane (30). The reflecting layer is positioned on a same side of the array of focusing micro- lenses as a focal plane of the focusing micro-lenses as such. The reflecting layer is arranged for reflecting at least a part of light incident on a surface (49) of the reflecting layer facing the array of focusing micro-lenses. The image fragment plane has image fragment structures (32). The array of focusing micro-lenses is positioned between the reflecting layer and the image fragment plane. The image fragment plane is arranged to, when being viewed refracted through the array of focusing micro-lenses towards the reflecting layer, reflected by the reflecting layer and refracted back through the array of focusing micro-lenses from the reflecting layer, give rise to an integral image. |
