Method and system for reproducing natural image
First Claim
1. A method of progressively reproducing a natural image by successively decoding and displaying data which are stored in memory means in at least three stages, said three stages including display of a retrieval image which is used for giving a general idea of the image, a soft copy image which has a sufficiently high resolution for display on display means and a hard copy image which has a sufficiently high resolution for printing on printer means, said data stored in the memory means including at least retrieval image data which is obtained by coding the natural image, soft copy image data which is obtained by coding a difference of the retrieval image and the soft copy image and hard copy image data which is obtained by coding a difference of the soft copy image and the hard copy image, said method comprising the steps of:
- (a) decoding the retrieval image data read out from the memory means to display a retrieval image on the display means;
(b) decoding the soft copy image data and a predetermined part of the hard copy image data read out from the memory means to display on the display means a soft copy image in which a predetermined part thereof is replaced by a hard copy image part which is described by the predetermined part of the hard copy image data;
(c) decoding the hard copy image data read out from the memory means to display on the display means a hard copy image excluding said hard copy image part; and
(d) printing the hard copy image on the printer means based on the hard copy image data decoded in said steps (b) and (c).

Abstract
A method of progressively reproducing a natural image successively decodes and displays data which are stored in a memory in at least three stages including display of a retrieval image which is used for giving a general idea of the image, a soft copy image which has a sufficiently high resolution for display and a hard copy image which has a sufficiently high resolution for printing. The data stored in the memory includes at least retrieval image data which is obtained by coding the natural image, soft copy image data which is obtained by coding a difference of the retrieval image and the soft copy image and hard copy image data which is obtained by coding a difference of the soft copy image and the hard copy image. The method comprises the steps of (a) decoding the retrieval image data read out from the memory to display a retrieval image, (b) decoding the soft copy image data and a predetermined part of the hard copy image data read out from the memory to display a soft copy image in which a predetermined part thereof is replaced by a hard copy image part which is described by the predetermined part of the hard copy image data, (c) decoding the hard copy image data read out from the memory to display a hard copy image excluding the hard copy image part, and (d) printing the hard copy image based on the hard copy image data decoded in the steps (b) and (c).

8. A natural image reproduction system for progressively reproducing a natural image by successively decoding and displaying stored data in at least three steps, said three steps including display of a retrieval image which is used for giving a general idea of the image, a soft copy image which has a sufficiently high resolution for display and a hard copy image which has a sufficiently high resolution for printing, said natural image reproduction system comprising:
-
display means; printer means; memory means for storing at least retrieval image data which is obtained by coding the natural image, soft copy image data which is obtained by coding a difference of the retrieval image and the soft copy image and hard copy image data which is obtained by coding a difference of the soft copy image and the hard copy image, decoding means for decoding the data stored in said memory means; a bus coupled to said display means, said printer means, said memory means and said decoding means; and control means, coupled to said bus, for controlling a read operation of said memory means, a decoding operation of said decoding means and transfer of data on said bus, said control means controlling said decoding means so that said three stages include decoding the retrieval image data read out from said memory means to display a retrieval image on said display means, decoding the soft copy image data and a predetermined part of the hard copy image data read out from said memory means to display on said display means a soft copy image in which a predetermined part thereof is replaced by a hard copy image part which is described by the predetermined part of the hard copy image data, and decoding the hard copy image data read out from said memory means to display on said display means a hard copy image excluding said hard copy image part, said control means controlling said printer means to print the hard copy image based on the hard copy image data decoded in said decoding means. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
