Multi-aperture imaging device, imaging system and method for capturing an object area

Imaging system exhibiting at least a first and at least a second multi-aperture imaging device, each a multi-aperture imaging device comprising:

• at least one image sensor;
• and
• an array of juxtaposed optical channels, wherein each optical channel comprises optics for projecting at least one partial area of an object area on an image sensor area of the image sensor;
• wherein a first optics of a first optical channel is configured to project a first partial area of the object area on a first image sensor area and a second partial area of the object area on a second image sensor area;
• wherein a second optics of a second optical channel is configured to project at least a third partial area of the object area on a third image sensor area;
• and
• wherein the first partial area and the second partial area are disjoint in the object area, and wherein the third partial area overlaps incompletely with the first partial area;
• further comprising, for the first and second multi-aperture imaging devices, at least one of:
• a common image sensor;
• a common focusing unit comprising at least one actuator for jointly adjusting a focus of the first and second multi-aperture imaging devices;
• an optical image stabilizer exhibiting a joint effect for an optical path of the first multi-aperture imaging device and for an optical path of the second multi-aperture imaging device for image stabilization along a first image axis and a second image axis by generating a translational relative movement between the image sensor and the array or the beam-deflector of the first or second multi-aperture imaging devices;
• and
• a common beam-deflector arranged between the array of the first and second multi-aperture imaging devices and the object area and configured to deflect an optical path of the optical channels of the first and second multi-aperture imaging devices.

Method for capturing an object area with an image sensor, comprising:

• projecting an object area with an array of juxtaposed optical channels, wherein each optical channel comprises optics for projecting at least one partial area of an object area on an image sensor area of the image sensor;
• projecting a first partial area of the object area on a first image sensor area and projecting a second partial area of the object area on a second image sensor area by a first optics of a first optical channel;
• and
• projecting a third partial area of the object area by a second optics of a second optical channel;
• such that the first partial area and the second partial area are disjoint in the object area and such that the third partial area incompletely overlaps with the first partial area;
• and such that the multi-aperture imaging device is implemented to at least one of:
• a configuration in which the third partial area is arranged within the object area between the first partial area and the second partial area;
• having an at least partly opaque structure for reducing stray light between the first image sensor area and the second image sensor area is arranged between the first image sensor area and the second image sensor area;
• such that a cross-section of the at least partly opaque structure tapers parallel to the image sensor in the direction of the array;
• having first partial area optics that is exclusively allocated to the first partial area and influences the projection of the first partial area on the first image sensor area such that the multi-aperture imaging device comprises a partial area diaphragm limiting an optical path through the first partial area optics;
• and
• having an aperture diaphragm that limits an optical path through the first optics.
