<p>The invention relates to a system (100) for zooming an image displayed in a viewport, wherein the image comprises a plurality of regions, each region of the plurality of regions having a zoom function associated with the region, the system comprising an input unit (110) for receiving a region input for selecting a region of the plurality of regions and for receiving a zoom input for zooming the image, and a zoom unit (120) for zooming the image based on the zoom input, using the zoom function associated with the selected region. The zoom function associated with each region of the plurality of regions may be defined in any way deemed useful. For example, it may be defined in such a way that the selected region or an interesting portion of it is displayed in the viewport or, vice versa, the selected region or an interesting portion thereof is removed from the displayed view of the image. Advantageously, the user does not always need to precisely select the zoom center, as the application will select the zoom center, based at least on the selected region.</p> |
