Patent attributes
A camera device having an enlarged or wide-angle field of view generates images of surroundings simultaneously using only one image capturing unit, such as an image sensor, for example. The camera device uses a diverting unit disposed upstream of the image capturing unit. The diverting unit includes so-called holographic optical elements which, based on their deflection structures, divert or deflect light so that the camera device can capture the wide-angle field of view, without generating imaging aberrations on the resulting image(s). The deflection structures are wavelength-selective and/or angle-selective. The total field of view is subdivided into individual angle-of-incidence regions by virtue of the properties of the deflection structures.
