- A water ring scanning method is disclosed for use in processing an initial data set, such as a video image frame, by writing a portion of data from the initial data set into a data string with a scanner. The initial data set is organized with at least one initial origin enveloped by a plurality of nested initial environs successively surrounding each other in the initial data set. The writing step starts by writing of the portion of the data from the initial data set into the data string at the RC grouping corresponding to the initial origin (initial water ring (0)) and by sequentially progressing the writing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring (1)) towards the family of RC groupings corresponding to a furthest nested initial environ (initial water ring (n)).
