A method for scaling an image

摘要

After scaling a portion of an image shown on the display of a handheld device in the form of a personal display assistant (PDA), the display of the PDA switches to show the scaled view of the portion of the image. This 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 the scaling process. The method also employs a smoothing technique to provide a more pleasing scaled view. <IMAGE>
