    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.

    摘要： A lens and color filter assembly contains lens units, and each lens unit is assigned to a single-color color filter unit. The lens and color filter assembly may be combined with pixel units such that a plurality of monochromatic, low-resolution images can be obtained, and the monochromatic images refer to shifted versions of the same image object. By a super-resolution technique comprising shift-compensation a mosaicked image is obtained which is then demosaiced. In the resultant image only few artifacts appear. Simple color filter arrays allow a simplified fabrication process and provide less chromatic aberrations at less computational effort.

    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： An optical system includes an optical element arranged in an optical path of an optical system. A point spread function of the optical element images out-of-focus object points with positive defocus value into image areas oriented along a first radial axis in an image plane and out-of-focus object points with negative defocus value into image areas oriented along a second radial axis in the image plane. A distance of the image areas to an optical axis of the optical system increases with increasing absolute defocus value.
