Abstract: A method of encoding a sequence of images comprises performing area-by-area loop filtering on at least one image of the sequence and disabling such area-by-area loop filtering on at least one other image of the sequence. The images of the sequence are associated with respective levels from a plurality of levels, the levels corresponding to different respective rate-distortion balances or to different image qualities, and the images on which the area-by-area loop filtering is disabled are determined in dependence upon the levels.

Abstract: 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.
