Abstract: A method and associated systems for implementing blur effects in 360-degree spherical space is disclosed. The method operates by identifying a pair of great circles 106 in a spherical view 100 which intersect orthogonally at a pixel (?0,?0) to which the blur effect is to be applied.

In some examples a series of points (?i,?i) along each great circle 106 are extracted and used to form one-dimensional sampling arrays which are swept across the two-dimensional image data in two orthogonal directions.
