Device comprising a multi-aperture imaging device for generating a depth map

A device comprising:

• a housing having two oppositely located main sides which are connected to each other via at least one edge side;
• a multi-aperture imaging device arranged in an interior of the housing and comprising:
• an image sensor arrangement;
• an array of adjacently arranged optical channels, each optical channel including an optic for projecting at least one partial field of view of a total field of view onto an image sensor area of the image sensor arrangement,
• a beam deflection means for deflecting an optical path of the optical channels, the beam deflection means comprising a plurality of facets, each optical channel having a facet associated with it;
• wherein one of the main sides comprises a passage area arrangement with at least one passage area, the passage area arrangement being set up to allow the optical paths to pass;
• wherein a position of the beam deflection means determines a size of the multi-aperture imaging device along an axial direction between the image sensor arrangement and the beam deflection means, and the beam deflection means is arranged adjacently to the edge side;
• and
• wherein the passage area arrangement is arranged within an edge area of the main side adjacently to the edge side;
• wherein the at least one passage area comprises, in relation to the edge side, a proximal edge and a distal edge, wherein the distal edge comprises a distance from the edge side which corresponds, at the most, to the sum of three times the diameter of the aperture diaphragm of the optic and the product of four times the window thickness, multiplied by the tangent of the angle, which corresponds to half the visual field angle along the longest side of the housing, divided by the number of partial images in the direction of the longest side of the housing, multiplied by the factor of the super resolution plus the number of images which is divided by the factor of the super resolution, in the direction of the longest side of the housing, minus one, multiplied by 5°;
• or
• wherein the at least one passage area comprises, in relation to the edge side, a proximal edge and a distal edge, wherein the proximal edge exhibits a distance from the edge side which corresponds, at the most, to double the diameter of the aperture diaphragm.

A method of providing a device, comprising:

• providing a housing comprising two oppositely located main sides which are connected to each other via at least one edge side, so that one of the main sides comprises a passage area arrangement having at least one passage area, the passage area arrangement being set up for allowing the optical paths to pass;
• arranging a multi-aperture imaging device in an interior of the housing, said arranged multi-aperture imaging device comprising:
• an image sensor arrangement;
• an array of adjacently arranged optical channels, each optical channel including an optic for projecting at least one partial field of view of a total field of view onto an image sensor area of the image sensor arrangement,
• a beam deflection means for deflecting an optical path of the optical channels, the beam deflection means comprising a plurality of facets, each optical channel having a facet associated with it;
• so that the optical channels comprise, in relation to the passage area arrangement and along an axial direction, along a course of the optical path of the optical channels between the image sensor arrangement and the beam deflection means, a channel-specific relative position of at least one of:
• the image sensor area;
• the optic;
• a reflecting surface of a facet associated with the optical channel as a distance between the reflecting surface of the facet and the optic of the optical channel, differing from another optical channel;
• such that the passage area arrangement causes, as compared to a relative position that is global to all the channels, a reduction of a required size of the passage area arrangement along the axial direction, which nevertheless enables unimpeded passage of the optical paths;
• or
• such that the channel-specific relative position causes, as compared to a relative position that is global to all the channels, an increase in the overlap of projections of beams of rays of the optical paths within an area of the passage area arrangement, and a size of the passage area arrangement is adapted to the increase in overlap, the projections being projected along a line extension direction of the array.
