Abstract
System for reproducing images and method thereof. An image acquisition device belonging to the system acquires the image and converts the image into indicia, which is defined by a digitally encoded compressed representation of the image in the form of one or more data image files. The image files are downloaded to a first printer which prints the indicia onto a first recording medium. The indicia printed on the first recording medium may overlay the image without interfering with enjoyment of the image because the indicia is printed in an invisible dye. In order to produce a quality reproduction of the original image, a sensor, which is disposed in sensing relationship to the indicia on the first recording medium, senses the indicia and generates a digital output signal in response to the indicia sensed thereby. An imaging device, such as a second printer, coupled to the sensor accepts the digital output signal and prints the quality reproduction of the image, including indicia, onto a second recording medium in accordance with the sensor output signal. The reproduction of the image can itself be reproduced in the same manner in order to provide a second quality reproduction. Of course, as many quality reproductions as desired may be provided in this manner. Each reproduction has the same quality as the original image because each reproduction is produced from the digital indicia printed on each reproduction. Also, rather than being printed, the reproduced image, which has the same quality as the original, may be displayed on a suitable monitor or electronically transmitted by means of one or more telecommunication systems.
Description




BACKGROUND OF THE INVENTION




This invention generally relates to apparatus and methods of reproducing images and more particularly relates to a system and method of reproducing images such that successive reproductions thereof (i.e., copies of copies) maintain the image quality of the original.




In order to reproduce a printed image, an analog image scanning system is often used. In such an analog system, a first record containing the printed image is scanned at a predetermined frequency (i.e., lines per unit time) and resolution (i.e., pixels per unit area). As the first record is scanned, a light source illuminates the image and a photo-sensitive electronic detector senses light reflected from the image. As the sensor senses the reflected light, the detector generates an analog signal in response to the reflected light sensed by the detector. A converter receives the analog signal and converts the analog signal into a digital signal, which is then transmitted to a computer whereat the digital signal is stored. The computer then passes the digital signal to a printer connected to the computer, so that a reproduction of the original image appearing on the first record is rendered onto a second record.




However, it has been observed that analog image scanning systems may produce reproductions having less image quality than the original. This degradation in image quality is exacerbated when successive reproductions (i.e., copies from copies) are made. Degradation in image quality is observed as different information being present in the reproduced printed image compared to the original image. That is, such analog systems may add information not present in the original. Alternatively, such analog systems may subtract information that was present in the original. This is primarily due to differences in calibration between equipment used to make the original image and equipment used to make the reproductions. The resulting reproduced image will thereby have degraded image quality because the information contained in the reproduced image is necessarily different from the information contained in the original.




Methods of controlling image quality in reproduced images are known. One such method is disclosed in U.S. Pat. No. 5,301,044 titled “Marking Material Containing A Taggant, And Method Of Producing An Image” issued Apr. 5, 1995 in the name of Joseph D. Wright. The method of the Wright patent uses taggants incorporated into marking materials (e.g., toner, ink or marking film) used to create and control reproduced images in a reproduction machine. According to this patent, the reproduction system identifies the particular material forming the image being scanned by recognizing one or more taggants therein. The taggant may fluoresce or reflect light of invisible wavelengths. Thus, taggant does not interfere with the color of the marking material in which the taggant is utilized within the image. When each taggant fluoresces or reflects light at a predetermined wavelength, the output light for each taggant is detected and compared to a table containing taggant wavelengths and information associated therewith, such as identity of toners, identity of inks or marking films, and spectral response of colorants in the toners and inks. This information is used by the reproduction system to enable or control color enhancement, correction, translation and other functions. Although this patent discloses a method of controlling quality of printed images produced by a reproduction system, this patent does not suitably address the problem of degradation of printed images appearing on copies made from copies. Moreover, this patent does not address the problem of unpredictable variability in image quality that occurs due to differences in calibration between copiers.




Therefore, there has been a long-felt need to provide an apparatus for and method of reproducing images such that successive reproductions thereof (i.e., copies of copies) maintain the image quality of the original.




SUMMARY OF THE INVENTION




The invention resides in a system for and method of producing a quality reproduction of an image. An image acquisition device belonging to the system acquires the image and converts the image into indicia, which is defined by a digitally encoded compressed representation of the image in the form of one or more data image files. The image files are downloaded to a first printer which prints the image and indicia onto a first recording medium. The indicia printed on the first recording medium may overlay the image without interfering with enjoyment of the image because the indicia is invisible, such as being printed in an invisible dye. In order to produce a quality reproduction of the original image, a sensor, which is disposed in sensing relationship to the indicia on the first recording medium, senses the indicia and generates a digital output signal in response to the indicia sensed thereby. An imaging device, such as a second printer, coupled to the sensor accepts the digital output signal and prints the quality reproduction of the image, including invisible indicia, onto a second recording medium in accordance with the sensor output signal. This reproduction of the image can itself be reproduced in the same manner in order to provide a second quality reproduction. Of course, as many quality reproductions as desired may be provided in this manner. Each reproduction has the same quality as the original image because each reproduction is produced from the invisible digital indicia printed on each reproduction. Also, rather than being printed, the reproduced image, which has the same quality as the original, may be displayed on a suitable monitor or electronically transmitted by means of one or more telecommunication systems.




An object of the present invention is to provide an apparatus and method of reproducing images such that successive reproductions thereof (i.e., copies of copies) maintain the image quality of the original.




A feature of the present invention is the provision of a recording medium having the image thereon and invisible digitally encoded compressed indicia representative of the image preferably overlaying the image.




Another feature of the present invention is the provision of a sensor to sense the indicia for subsequent printing or display of a quality reproduction on an output device.




An advantage of the present invention is that successive reproductions of an image (i.e., copies of copies) can now be provided while maintaining the image quality of the original irrespective of variability in scanning input or output devices chosen to acquire or print and display the reproduced image.




These and other objects, features and advantages of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION




The present description will be directed in particular to elements forming part of, or cooperating more directly with, apparatus in accordance with the present invention. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art.




Therefore, referring to

FIGS. 1

,


2


and


3


, there is shown the subject matter of the present invention which is a system, generally referred to as


10


, for reproducing an image


20


of a subject


30


such that successive reproductions of image


20


(i.e., copies of copies) maintain the image quality of the original image


20


. Of course, subject


30


may be a human subject (as shown), an inanimate object or alpha-numeric lettering. As used herein, the terminology “image” includes any blank border region


35


. Of course, “Image quality” is ascertainable by observing whether different information (i.e., more or less information) is present in the reproduced image compared to the original. To achieve constant image quality, system


10


first prints “invisible” indicia


40


, digitally representing image


20


, onto any desired portion of the original image


20


, which indicia


40


may be “appended to” image


20


. As used herein, the terminology “appended to” means indicia


40


is printed over the surface of image


20


or under the surface of image


20


or between any combination of intermediate color planes comprising image


20


. In addition, the terminology “appended to” also includes the case where indicia


40


is laid down so that it is interposed between pixels comprising image


20


, which is most useful in a half-toning system. As described in more detail hereinbelow, system


10


then reads indicia


40


and subsequently produces a quality copy of the original image


20


. For reasons described more fully hereinbelow, indicia


40


, which is printed on image


20


, is preferably in the form of a two-dimensional encoded variable data array comprising a digital data image file, which may be compressed to conserve space. In this regard, it is known that data compression is desirable because data compression reduces the amount of electronic “space” the data image file occupies in electronic memory. Of course, such a compressed data image file must be later decompressed before the data image file can be used for the purpose disclosed herein. To facilitate later decompression of the compressed data image file, the data image file is initially compressed into any one of many well-known file formats. On the other hand, the two-dimensional encoded variable data array defining the digital data image file may comprise uncompressed data, if desired. However, in this case, more electronic “space” is required for storing the uncompressed data image file in electronic memory. Examples of such known file formats usable with the invention include JPEG (Joint Photographic Excellence Group), GIF (Graphic Interchange Format), TIFF Tagged Data Image File Format), BMP (Bit Mapped), FlashPix, or Photo CD Image Pac. As used herein, the terminology “variable data” means data which may vary from one record to another.




Referring to

FIG. 4

, indicia


40


, which may laid-down (i.e., printed) over image


20


, is preferably “invisible” dye (i.e., dye imperceivable to the naked eye) in order to preserve fidelity and aesthetic enjoyment of image


20


when indicia


40


is laid-down over image


20


. More specifically, indicia


40


is preferably a dye having spectral absorption in the invisible infrared region or ultraviolet region of the radiation spectrum. Such a dye is selected so that the dye does not absorb or fluoresce light in the human visible spectrum, but which is nonetheless visible to optical reading devices capable of illuminating indicia


40


with infrared light or ultraviolet light. For this purpose, the dye may be 4,4′-bis (triazin-2-ylamino)stilbene-2,2′-disulfonic acids; 2-(stilben-4-y)naphthotriazoles; or 2-(4-phenylstelben-4-yl)benzoxazoles, or other suitable dye.




Still referring to

FIG. 4

, indicia


40


is preferably overlaid (i.e., printed) on image


20


, which is itself printed on a first recording medium


50


. First recording medium


50


includes a substrate


60


, which by way of example only, and not by way of limitation, may be a suitable paper comprising, for example, a cellulose-based ester material (nitrate or acetate, or the like). Overlaying substrate


60


is a first layer (i.e., first color plane)


70


formed of a first colorant material, such as a magenta dye. Overlaying first layer


70


is a second layer


80


(i.e., second color plane) formed of a second colorant material, such as a cyan dye. Overlaying second layer


80


is a third layer


90


(i.e., third color plane) formed of a third colorant material, such as a yellow dye. The three layers are magenta, cyan and yellow dyes in CYM color space. However, it should be appreciated that the three dyes may alternatively be red, green and blue dyes in RGB color space. Overlaying third layer


90


is a fourth layer


100


(i.e., fourth color plane), which includes image


20


printed in the previously mentioned invisible dye. If desired, a fifth layer


110


(i.e., fifth color plane) may overlay the entirety of fourth layer


100


, which fifth layer


10


is a clear protective layer for protecting fourth layer


100


from damage. For this purpose, fifth layer


110


may be formed of polyvinyl acetale or adhesive-backed transparent polyester substrate. The manner in which system


10


forms indicia


40


(i.e., fourth layer


110


) on first recording medium


50


is described more fully hereinbelow.




Therefore, returning to

FIG. 1

, an image acquisition device, such as a digital camera


119


, is provided for capturing image


20


of subject


30


. Camera


119


may be a Kodak DC


120


Camera™, or the like, available from the Eastman Kodak Company located in Rochester, N.Y. Camera


119


includes a flash unit (not shown) for illuminating subject


30


, a viewing lens or digital image display area (not shown) for viewing subject


30


, and a lens (also not shown) for receiving light


120


reflected from subject


30


. Camera.


119


transforms reflected light


120


into a digital data image file representing subject


30


and stores the digital data image file in memory (not shown) of camera


119


. The digital data image file may be in any one of known image file formats, such as JPEG, GWF, TIFF, BMP, FlashPix, or Photo CD Image Pac. It is important that the data image file format be compressed. This is important so that the data image file can be rendered in a two-dimensional data array that is within the printable area available on first recording medium


50


. This is also important in order to conserve electronic “space” in the memory of camera


119


. Camera


119


then generates an output signal containing the digital data image file which was temporarily stored in memory of camera


119


. This output signal travels along a first cable


121


to a image first processor


122


for processing, as described more fully presently.




Referring now to

FIG. 5

, image first processor


122


includes an input/output interface


123


, which receives the output signal transmitted from camera


119


. In order to perform its processing function, image first processor


122


also includes a CPU (Central Processing Unit)


124


and a memory unit


125


. Memory unit


125


includes one or more image processing routines


126


used to control CPU


124


when processing the compressed image data file. In addition to image processing routines


126


, memory unit


125


also includes an area data storage and image rendering memory space


127


for storing the image data file received from camera


119


. It is appreciated that there may be a plurality of data files respectively representing a full-color rendered image of subject


30


. As defined herein, a “rendered image” is an image data file(s) which has been processed and formatted for printing. Thus, such a rendered image data file(s) may comprise a plurality of two dimensional data sets, each data set corresponding to a different colorant layer to be printed. There may be three colorant layers comprising, for example, magenta, cyan and yellow dyes in CYM color space. However, it may be appreciated that the three dyes may alternatively be red, green and blue dyes in RGB color space. The “invisible” colorant comprising indicia


40


is treated as an additional colorant layer to be rendered. Therefore, in rendering color images, CPU


124


generates from the image data file(s) received from memory camera


119


, a separate data file corresponding to each of the three colorants in addition to the image data file comprising the invisible colorant.




Referring again to

FIG. 1

, a first image forming device, such as a first printer


130


, is connected to input/output interface


123


by a second cable


140


for receiving an output signal generated by image first processor


122


, which output signal comprises the three image data planes which may be in compressed file format, if desired, corresponding to each of the three dyes. In addition, the output signal comprises the image data plane (i.e., indicia


40


) which includes the invisible dye in compressed file format. When first printer


130


receives this output signal from image first processor


122


, first printer


130


prints indicia


40


and image


20


onto first recording medium


50


. It is understood from the teachings hereinabove, that image


20


comprises first, second and third colorant layers


70


/


80


/


90


preferably overlaid one upon the other. Indicia


40


overlays third colorant layer


90


of image


20


without interfering with visual enjoyment of image


20


because indicia


40


is formed in fourth layer


100


as an “invisible” colorant. First printer


130


may be a thermal dye transfer printer, inkjet printer, electrophotographic printer or the like. After first printer


130


prints encoded and compressed indicia


40


and image


20


onto first recording medium


50


, indicia


40


is ready to be optically scanned to produce a quality reproduction of image


20


, as described more fully hereinbelow.




Referring now to

FIGS. 1 and 6

, a sensor


150


is disposed in sensing relationship to indicia


40


for sensing indicia


40


. Sensor


150


senses the two-dimensional data array of indicia


40


and processes the sensed information such that the two-dimensional data array of indicia


40


is converted back to digital data in a compressed file format. Sensor


150


is preferably a hand-held wand


160


and comprises an elongate housing


170


having a focusing lens


180


at an end portion thereof. Although sensor


150


is described herein as a hand-held wand, it is appreciated that sensor


150


may be a flat-bed scanner (not shown), such as the KODAK IMAGELINK SCANNER 923™ available from the Eastman Kodak Company located in Rochester, N.Y. Alternatively, sensor


150


may be a feed-through scanner, a drum scanner, a film scanner, or other scanning device. When sensor


150


is a hand-held wand, a spectral filter


190


is disposed in housing


170


and is co-axially aligned with, but spaced-apart from, lens


180


for letting through a predetermined wavelength of light and blocking all other wavelengths. Therefore, filter


190


will only allow the wavelength of light corresponding to the fluorescence or absorption wavelengths of light from indicia


40


. Alternatively, filter


190


may be coated onto lens


180


, rather than being spaced-apart from lens


180


, so that sensor


180


is compact. A two-dimensional array image detector


200


, such as a CCD (Charge-Couple Device), is in optical communication with filter


190


for detecting light


205


passing through lens


180


and filter


190


. Alternatively, detector


200


may be a CMOS device, which is a device formed by the combination of a PMOS (p-type-channel metal oxide semiconductor device) with an NMOS (n-type-channel metal oxide semiconductor device). Thus, detector


200


serves as a semi-conductor storage device to convert light


205


detected thereby into electronic digital form. An auxiliary light source


210


may be provided, if desired, for enhancing detection of two-dimensional indicia


40


by illuminating indicia


40


. It should be appreciated that light source


210


may be a laser for emitting a laser light beam to be intercepted by indicia


40


and reflected therefrom. In this case, detector


200


is a laser light detector for detecting the laser light beam reflected from indicia


40


. In any case, detector


200


is preferably capable of detecting the entire two-dimensional image


20


without a user of system


10


having to move wand


160


in a scanning motion over indicia


40


in order to sense indicia


40


. Also disposed in housing


170


are image sensor electronics


220


for driving detector


200


data capture. That is, sensor electronics


220


controls rate of data capture and converts analog charges on CCD detector


200


into digital data format. Electrically connected to sensor electronics


220


is a memory


230


. The purpose of memory


230


is to store digital representation of indicia


40


. Electrically connected to memory


230


is a second processor


240


. The purpose of second processor


240


is to decode and decompress the data according to requirements of an associated output device. The image of indicia


40


received through lens


180


is an analog of image


20


. That is, indicia


40


sensed by sensor


150


is in analog form, which should be converted back into a digitally encoded and compressed data image file in order to be usable for subsequently reproducing image


20


. Second processor


240


then transmits this digitally encoded and compressed output signal, such as by means of a third cable


250


and a fourth cable


260


, to a second printer


270


for reprinting image


20


on a second recording medium


280


without degradation of image quality, as described more fully presently. Second printer


270


may be a thermal dye transfer printer, inkjet printer, electrophotographic printer or the like. Alternatively, the output signal generated by processor


240


may be transmitted by means of third cable


250


and a fifth cable


290


to a display unit


300


, which may be a computer monitor, television monitor, suitable “overhead” projection device, or the like, for displaying image


20


. In addition, the second processor


240


output signal may be transmitted by means of third cable


250


and a sixth cable


310


to a first telecommunications system


320


, which in turn transmits (e.g., by broadcasting) the second processor


240


output signal to a second telecommunications system


330


for printing or display of reproduced image


20


. Second printer


280


, display unit


300


, first telecommunications system


320


or second telecommunications system


330


, as the case may be, receives the converter output signal and thereafter decompresses and decodes the second processor


240


output signal into its digital binary representation. In all cases, invisible indicia


40


resides on all reproductions of image


20


, such that the indicia


40


residing on respective reproductions of image


20


may be scanned in the manner described hereinabove. Thus, each reproduction of image


20


has the same image quality as image


20


appearing on first recording medium


50


because complete information pertaining to the original image


20


is retained undegraded in the two-dimensional digital data array defining indicia


40


.




Therefore, it should be understood from the description hereinabove that digital camera


119


captures light


120


reflected from subject


30


and transforms light


120


preferably into three two-dimensional image data files representing full-color image


20


of subject


30


. Camera


199


also generates indicia


40


, which is another image data file that represents image


20


as a two-dimensional encoded compressed variable data array. These image data files are transmitted to image first processor


122


, which processes the data files to first printer


130


. First printer


130


prints indicia


40


and image


20


onto first recording medium


50


.




It should be understood from the description hereinabove that when a quality reproduction of image


20


is desired, indicia


40


is first sensed by wand


160


, which is preferably capable of detecting the entire two-dimensional indicia


40


without the user having to move wand


160


in a scanning motion over indicia


40


in order to sense indicia


40


. The scanning signal generated by wand


160


is transmitted to second printer


270


for printing image


20


on second recording medium


280


without degradation of image quality. Alternatively, the scanning signal generated by wand


160


may be transmitted to display unit


300


. As yet another alternative, the scanning signal generated by wand


160


may be transmitted to a first telecommunication system


320


, which may be a cellular phone, for subsequent transmission to a second telecommunication system


330


.




In another embodiment of the present invention, first printer


130


may be of a type which “prints” indicia


40


in fourth layer


100


in the form of magnetic media. In this case, wand


160


is selected such that it senses/reads the magnetic emanations of the magnetic media before producing its output signal which is transmitted to second printer


270


, display unit


300


and/or first and second telecommunication systems


320


/


330


.




It may be appreciated from the teachings herein that an advantage of the present invention is that successive reproductions of an original image (i.e., copies of copies) can now be provided while maintaining the image quality of the original irrespective of variability in scanning input or output devices chosen to acquire or print and display the reproduced image. This is so because each reproduction is made in accordance with digital indicia rather than by the analog means of the prior art.




While the invention has been described with particular reference to its preferred embodiments, it is understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements of the preferred embodiments without departing from the invention. For example, indicia


40


need not be invisible; rather indicia


40


may be visible but printed in a “blank area” (e.g., border


35


) on first recording medium


50


, so as not to disturb the aesthetic enjoyment of image


20


.




As is evident from the foregoing description, certain other aspects of the invention are not limited to the particular details of the examples illustrated, and it is therefore contemplated that other modifications and applications will occur to those skilled in the art. It is accordingly intended that the claims shall cover all such modifications and applications as do not depart from the true spirit and scope of the invention.




Therefore, what is provided is an apparatus and method of reproducing images such that successive reproductions thereof (i.e., copies of copies) maintain the image quality of the original.
