Abstract
A method and a system for processing multi-aperture image data are described, wherein the method comprises: capturing image data associated with one or more objects by simultaneously exposing an image sensor in an imaging system to spectral energy associated with at least a first part of the electromagnetic spectrum using at least a first aperture and to spectral energy associated with at least a second part of the electromagnetic spectrum using at least a second and third aperture; generating first image data associated with said first part of the electromagnetic spectrum and second image data associated with said second part of the electromagnetic spectrum; and, generating depth information associated with said captured image on the basis displacement information in said second image data, preferably on the basis of displacement information in an auto-correlation function of the high-frequency image data associated with said second image data.
