摘要： A lens unit of an imaging unit features longitudinal chromatic aberration. From an imaged scene, an imaging sensor unit captures non-color-corrected first images of different spectral content. An intensity processing unit computes broadband luminance sharpness information from the first images on the basis of information descriptive for imaging properties of the lens unit. A chrominance processing unit computes chrominance information on the basis of the first images. A synthesizing unit combines the computed chrominance and luminance information to provide an output image having, for example, extended depth-of-field. The imaging unit may be provided in a camera system, a digital microscope, as examples.

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.
