Abstract
A method for scaling a portion of an image shown on the display of a PDA is disclosed. After scaling, the display of the PDA switches to show the scaled view of the portion of the image. This method essentially involves the scaling of a first set of display information which forms the portion of the image, into a second set of display information which makes up the scaled view. During the scaling process, a series of look-up tables containing display conversion information are generated. An address-indexing technique is then used with the look-up tables to achieve an efficient and fast scaling process. The method also employs a smoothing technique to provide a more pleasing scaled view.
