Abstract

A method of masking part of an image for display comprises assigning (506) pixel values to respective pixels outside a region of interest (2) to obtain a masked region (3), the pixel values being determined according to a mask function, the mask function being dependent on a distance of a position of a respective pixel to the region of interest (2), for obtaining a smooth transition region (5) in the masked region (3) at a boundary (6) of the masked region towards the region of interest (2). The mask function may be a darkening filter. The pixels in the transition region (5) are assigned brighter pixel values at pixel locations closer to the region of interest and darker pixel values at pixel locations further away from the region of interest.
