Currently, various television standards use different aspect ratios. For example, a wide screen aspect ratio of 16:9 is gaining popularity over the existing TV broadcasts that use 4:3 aspect ratio. A method of scaling an image horizontally with a uniform or non-uniform scaling ratio is referred to as "panoramic scaling". A device 100 and method 800 of scaling an image 102 by means of a scaling function 121 that is generated on the basis of a motion vector 101 of at least a part of the image 102 is disclosed. The device 100 can be used in an image processing apparatus or in an image display apparatus for converting a first image with a first aspect ratio to a second image of a second aspect ratio. The disclosed device 100 is useful in reducing the visual distortion introduced by the panoramic scaling especially in case of moving objects in a scene. |
