In a method and system for providing virtual output images from an array of image capturing devices image data (Ii(s,t), I2(s,t)) is taken from the devices (Ci, C2). This image data is processed by convolving the image data with a function, e.g. the path (S) and thereafter deconvolving them, either after or before summation (SUM), with an inverse point spread function (IPSF) or a filter (HP) equivalent thereto to produce all-focus image data (I(s,t)). 2. Method as claimed in claim 1 , wherein adding and inverse filtering comprises the method steps of:{'sub': 1', '2', 'K', 'N', '0z1', '0z2, 'constructing from the input image data of the individual images (I(s,t), I(s,t), I(s,t), I(s,t)) image data for a number of synthetically focused images at a number of depths (I(s,t), I(s,t)),'}{'sub': '0', 'adding the image data of the number of synthetically focussed images at various depths to form the image data for an integrated blurred image (Ĩ(s,t)), and thereafter'}{'sub': 0', '0', '1', '2', 'K', 'N, 'deconvolving the integrated blurred image (Ĩ(s,t)) using an inverse point spread function (IPSF) for producing the image data for the virtual image (Ī(s,t)), from the input image data of the individual images ((I(s,t), I(s,t), I(s,t), I(s,t)).'}3. Method as claimed in claim 2 , wherein the method comprises:{'sub': 1', '2', '0', '0', '1', '2', '0', '0, 'a for a number of depths (z,z, . . . ) shifting the individual input images provided by the image capturing devices in proportion to the distance between the position of the particular image capturing devices and the virtual camera position (u,v) and in dependence on the specific depth (z, z, . . . ), to align the individual input images to the virtual camera position (u,v) and then'}{'sub': '0z1', 'b. adding the image data for the shifted images at each depth together to form image data of a synthetically focused images at the number of depths (I(s,t)),'}{'sub': '0', 'c adding the number of synthetically focussed images to ...
