| 1. A method for accessing a region of an encoded image comprising a plurality of segments that are encoded and stored according
to a predetermined encoding order, wherein the method comprises:
a step of comparing a position of the current encoded segment with the region of the encoded image to be accessed;
a step of selecting the type of decoding of the current encoded segment according to the result of the comparing step; and
a step of repeating the comparing step and the selecting step, on a preceding encoded segment, the preceding encoded segment
preceding the current encoded segment in an encoding order,
wherein the steps are performed by a processor.
