What is described are a method and a device, wherein two types of individual images are captured, namely a set of individual images captured simultaneously, and a further set of individual images captured in temporal succession. Among said two sets of individual images, individual images are selected which in combination result in a panoramic image.

Generating panoramic images

The fact that a beam-deflecting device can be produced cost-effectively and without any losses of optical quality of the multi-aperture imaging device is used when a carrier substrate is provided for the same, wherein the carrier substrate is common to the plurality of optical channels and is installed with a setting angle, i.e. oblique with respect to the image sensor in the multi-aperture imaging device such that a deflection angle of deflecting the optical path of each optical channel is based, on the one hand, on the setting angle and, on the other hand, on an individual inclination angle with respect to the carrier substrate of a reflecting facet of a surface of the beam-deflecting device facing the image sensor, the reflecting facet being allocated to the optical channel.

Multi-aperture imaging device having a beam-deflecting device comprising reflecting facets

Providing a multi-aperture imaging device having a single-line array of optical channels arranged next to one another with and adjuster for channel-specifically changing a relative position between an image sensor region of a respective optical channel, the optics of the respective optical channel and a beam-deflecting device of the respective channel or for channel-specifically changing an optical characteristic of the optics of the respective optical channel or an optical characteristic of the beam-deflecting device relating to deflecting the optical path of the respective optical channel, and a storage having default values stored therein and/or a controller for converting sensor data to default values for channel-specifically controlling the adjusting device is used to reduce requirements to, for example, manufacturing tolerances of the multi-aperture imaging device and/or requirements to the multi-aperture imaging device as regards position and shape invariance relative to temperature variations such that the additional complexity entailed by this procedure is compensated again.

Multi-aperture imaging device having channel-specific adjustability

A multi-aperture imaging device includes an image sensor and an array of optical channels, each optical channel including optics for projecting a partial field of view of a total field of view on an image sensor area of the image sensor. The multi-aperture imaging device includes a beam deflector for deflecting an optical path of the optical channels and an optical image stabilizer for an image stabilization along a first image axis by generating a translatory relative movement between the image sensor and the array and for an image stabilization along a second image axis by generating a rotational movement of the beam deflector.

Multi-aperture imaging device, imaging system and method for providing a multi-aperture imaging device

An improved ratio between hardware/manufacturing expenditure, on the one hand, and picture quality, on the other hand, when using a multi-channel optical element is achieved in that the samples of the pixels are arranged in accordance with an imaging direction from which the optical element images objects on the respective pixel, or with a lateral imaging position in a focal-depth area that is imaged to the respective pixel by the optical element, and when the distribution, thus arranged, of samples of the pixels is interpolated at intersection points of a regular grid extending over the entire distribution of the samples. In this manner, processing is standardized across the entire picture, so that transition problems between the subareas are avoided.

Picture capturing apparatus and method using an image sensor, an optical element, and interpolation

A refraction at a suitably structured surface for example with an arrangement of the same between image plane and mapping optics is used to realize on the one hand a desired aliasing filtering or spatial low-pass filtering on the image plane wherein on the other hand the manufacturing of such structured surfaces may be realized in a cost-effective way. In addition to that, the plate thickness except for the amplitude of the surface structure and aspects of the stability of the plate is of no importance for handling the same, so that the integration into optical systems is facilitated.
