Abstract: 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.

Abstract: In a method for estimating motion vectors for blocks of a current video image in a sequence of video images, each video image being divided into a plurality of blocks, the following is performed: determining (13) a motion vector for a block of a previous video image; projecting (16) the determined motion vector of the block of the previous video image to a block position of the current video image, thereby obtaining a projected motion vector; and performing (18) a motion estimation for a current block of the current video image on the basis of the projected motion vector, thereby obtaining a motion vector for the current block of the current video image.
