<p>Electronic still imaging apparatus includes a digital signal processor (22) that transforms blocks of digital image signals derived from an image sensor (12) into sets of coefficient signals and encodes the coefficient signals into a stream of compressed signals. In addition, the digital processor generates reduced resolution image signals from the digital image signals and downloads both the compressed (high resolution) image signals and the reduced resolution image signals to a removable digital memory (24). By associating each high resolution image with its low resolution counterpart in a common multi-format image file, the image can be quickly accessed and a low resolution review image can be put up on a display device (116) without waiting for expansion and processing of the larger full resolution image.</p> |
