Method for enlargement/reduction of image data in digital image processing system and circuit adopting the same

摘要

An image data enlargement/reduction method for use in a digital image processing system, performs enlargement and reduction of image data by employing a small quantity of data from a look-up table while satisfying a large range of enlargement and reduction operations as requested by a user, with a simplified circuit structure. Enlargement/reduction data is calculated by a microprocessor so that the zooming ratio can be easily modified by a software change.
