摘要： A lens unit (120) shows longitudinal chromatic aberration and focuses an imaged scene into a first image for the infrared range in a first focal plane and into a second image for the visible range in a second focal plane. An optical element (150) manipulates the modulation transfer function assigned to the first and second images to extend the depth of field. An image processing unit (200) may amplify a modulation transfer function contrast in the first and second images. A focal shift between the focal planes may be compensated for. While in conventional approaches for RGBIR sensors contemporaneously providing both a conventional and an infrared image of the same scene the infrared image is severely out of focus, the present approach provides extended depth of field imaging to rectify the problem of out-of-focus blur for infrared radiation. An imaging system can be realized without any apochromatic lens.

摘要： A method and optical system for determining a depth map of an image, the method including: determining a first focus measure of a first color in at least one region of the image; determining a second focus measure of a second color in the at least one region of the image; determining a ratio of the first and the second focus measure; and determining the depth map based on a ratio of the first and second focus measure.

摘要： In a method for determining field of view dependent depth map correction values for correction of a depth map of an image taken with a lens having a field of view the following is performed: obtaining (31) relative depth information for at least two different depths and at least two different predetermined locations of the field of view of the lens; receiving (32) an image; determining (33) a depth of the received image; and determining (34) on the basis of the determined depth of the received image at least one depth map correction value on the basis of the relative depth information.
