ABSTRACT:
A method of modifying the region displayed in a window of predetermined size within a digital image represented by several resolution levels, between a first region (display_zone) of the digital image displayed at a first resolution (R) and a second region (final_zone) of the digital image including the first region (display_zone) and different from it, comprises the steps of: —selecting (S406), from the stored image parts (bitmap[r]) including the first region (display_zone), a stored image part (bitmap[k]) with a second resolution (k) that is the maximum among the resolutions of said parts, and less than the first resolution (R); —obtaining (S84, SE86) from the selected image part (bitmap[k]) at least one region included in the second region (final_zone) and including the first region (display_zone); —displaying (S88) the region obtained in said window. A corresponding method of displaying an image at plural resolutions is also proposed. Corresponding devices are also provided.
