Abstract
Described is a technique for viewing a document page on a small display such as a mobile phone or PDA. The page can come from a scanned document (bitmap image) or an electronic document (text and graphics data plus metadata). The page with text and graphics is segmented into regions. For each region, a scale-distortion function is constructed based on image analysis. During interactive viewing of the document, as the user navigates by moving the viewport around the page, the zoom factor will be automatically adjusted by optimizing the scale-distortion functions of the regions in the viewport.
