1. A method performed by an image processor, the method comprising: generating respective virtual image sheets for frames captured from different camera locations and different camera orientations, said generating the virtual image sheets including projecting texture maps of the captured frames over wire frames corresponding to optics settings of the camera; positioning the generated virtual image sheets at locations and orientations within a viewing space that correspond to the different camera locations and the different orientations; rendering the positioned virtual image sheets into a mosaic viewed from a reference point of the viewing space; and determining the reference point of the viewing space from which to view the mosaic based on a spatial distribution of the different camera locations, wherein said determining the reference point comprises choosing the reference point's location at equal distances from the different camera locations.
