MOBILE BROWSER WITH ZOOM OPERATIONS USING PROGRESSIVE IMAGE DOWNLOAD

摘要

A method and mobile device for providing fast rendering of a web page and zoom capability using progressive image download. A data server requests the web page and converts images within the webpage into a progressive format before forwarding the web page data to the mobile device. The initial fully zoomed-out view of the web page is rendered using initial low resolution image data first received at the device. As additional progressive resolution data is received, the device is capable of zooming in to portions of the web page using the higher resolution data. If interpolations are used in rendering an image at a particular zoom level, then the image is repainted in higher resolution as additional progressive resolution data is received.
