Abstract: A method for operating a mobile terminal including an image recording device includes capturing at least one recording of a scene and checking at least one of optionally several recordings checked for the presence of a light source. Subsequently, a position of the light source is determined relative to an optical center and a shape, an intensity and/or a color is determined for the light source. An algorithm trained in relation to imaging properties of a given optical unit is then used to generate a flare image of a lens flare for this light source and the given optical unit using the position of the light source. The flare image is subsequently combined with the recording to form a combination image and the combination image is stored in a memory component.

Abstract: A lens system for a camera objective has a plurality of optical lenses that are arranged one after another along an optical axis and are configured for imaging in the visually perceivable spectral range. At least a part of the optical lenses has two types of lens faces that intersect a beam path of the camera objective. At least three of said lens faces are provided with a first anti-reflective coating which has a larger reflectance in at least one partial region of the visible spectral range than a second anti-reflective coating of the remaining lens faces. In addition, a camera objective including the lens system and a method for producing a lens system are provided.

Abstract: A method of aligning a lens device includes: coupling an optical free-space beam that propagates along a first direction into an access port of an optoelectronic component, the first, a second, and a third direction being mutually perpendicular; positioning the lens device inside a free-space beam path, the lens device having an adjustment lens configured to focus radiation in only the second direction; moving the lens device along the second direction to align the adjustment lens with respect to the access port at an initial aligned position at which the optical free-space beam is one-dimensionally focused by the adjustment lens and at least a portion of a resulting one-dimensionally focused beam is input into the access port; and starting from the initial aligned position, moving the lens device in the second and/or third directions to position an optical element of the lens device in front of the access port.
