Abstract
An embedded coding scheme is used to dynamically changes the size of compressed images and as a result image quality according to the number of stored pictures. As more images are captured, the image storage device makes room for newly captured images by truncating existing compressed embedded coded bitstreams of previously stored images. The embedded digital image storage device can thus store a virtually unlimited number of images by dynamically trading-off between the number of stored images and image quality.
