摘要：Zooming technology is an essential part of Personal Digital Assistants (PDAs) for today‟s informationconcerted world, which caused many problems for small screen interfaces. This paper introduces zooming applicationssuch as a normal zoom, a focus zoom, and a search zoom which are based on geometric and semantic zooming methods[1] [2]. Digital images are the most common and convenient means of conveying or transmitting information. They sharesinformation about positions, sizes and relationships between objects. Digital image zooming is very important processin image processing. Basically zooming done by two steps: - the creation of new pixels locations and to assignment ofgray level to those new locations. Digital image zooming with respect to their higher storage size and within MultiMedia is a important subject in image processing. Zoom in a digital image means replacing the number of displaypixels per image pixel only in appearance. Digital image shrinking is done in same manner as zoom in. In this paper weare using interpolation methods which have many advantages as we discussed.
