CHANGING THE ASPECT RATIO OF IMAGES TO BE DISPLAYED ON A SCREEN

摘要

The present invention relates to a method, image processing device, image display device including an image processing device and computer program product for changing the size of presentation of an image data stream (X) provided in a image data format. The image processing device ( 12 ) comprises at least one image decoding unit ( 22 ) selecting at least parts of an image data stream (X<SUB>O</SUB>, X<SUB>S</SUB>) having a first original field of view to be presented in, and obtaining values of pixel regions from an area larger than the original field of view from the selected image data (X<SUB>S</SUB>). The image processing device changes field of view by calculating an image to be displayed conforming to a second field of view based on the obtained data and values. Image data intended to be presented in the first field of view can then be displayed in the second field of view.
