Method and apparatus for processing at least one digital image, the computer program element and computer readable storage medium

The invention relates to a method and an apparatus for processing at least one digital image, a computer program element and a computer-readable storage medium.

2 shows a conventional recent sequence of a method for printing, for example, advertising brochures or displaying product packaging that are created in a first printing format in a lithography institution as a digital image.

2 shows a block diagram 200 the usual

Procedure. In a lithographic institution 201, a first digital master of a product or packaging of a product is created (step 201). The first digital

A master located in a first printing format, and is, for example, by a conventional

Image processing program, such as the Photo Shop ™ program or a suitable desktop publishing program (desk-top

Publishing program) created.

For displaying the information in the first digital master of the following color spaces is used, for example:

• primarily the CMYK color space, alternatively

• the RGB color space, or

• The sRGB color space.

The digital master in the first print format represents the provided by the lithography institution 201 resolution data of the digital master. By using the digital master, a film is exposed (step 203) and using the exposed film printing plates are created (step 204).

Using the printing plates, a contact pressure is produced as a prototype of the product or the packaging

(Step 205) and using the press sheet, the product itself or the packaging itself as a prototype (Dummy) of the product or packaging is created

(Step 206).

The packaging 207 is supplied by the lithography institution 201 to the actual manufacturer 208 of the product for which the packaging is intended 207th

The product manufacturers 208 created upon receipt of the package, upon receipt of the prototype that is, (step 209), a photographer a photograph of the package (step 210) and scans in a subsequent process step (Step 211) the picture produced.

In this context it should be noted that under a photograph in the description of the prior art usually an analog photography is to be understood and only in exceptional cases, a digital photograph.

From the scanned analog photo or scanned digital photo a duplicate slide is created, again by a film is exposed (step 212).

The slide is scanned in a further step in a lithography institution, so that a digitized image is generated (step 213).

The digitized image is stored on a data carrier, for example on a CD-ROM together with a variety in the same way digitized images generated, the total of, for example, an electronic document for printing a product catalog or for presentation on an Internet / Intranet site form (step 214).

The disk 216 is delivered to a printing company 217, by which the actual pressure of a catalog, generally an expression 217 of the respective container or of the respective product is produced.

Due to the very complex and expensive procedure according to the prior art, wherein a multiple, connected with a corresponding loss of information and associated loss in quality of images of the product or the packaging analog photo images and digitization is photographs of packaging a high in the final expression rather inferior image is printed, which must then be customized in the colors still usually.

Further, this complex procedure results in a considerable time delay in the implementation of the particular product or packaging of creating the high-resolution data up to the actual image expression, which may result in very short product cycles to particular that prints, in particular also all product catalogs are created which no longer correspond to the current product range of a producer company.

The invention is based on the problem of specifying a method and an apparatus for processing a digitized image, which is compared with the above-described procedure simplified.

The problem is solved by an apparatus and a method for processing a digital image, a computer program element as well as by a computer readable storage medium having the features according to the independent claims.

In a method for processing at least one digital image, the image is in a first compressed format with a first color space representation which digital image is created, for example, by a conventional image processing program such as Photo Shop ™ or of a suitable DTP program from a lithography institution.

As the first color space representation of color space representations of the following is used according to an embodiment of the invention: • A color space representation in the RGB color space;

• a color space representation in the CMYK color space;

• a color space representation in the sRGB color space (Super RGB color space).

The thickness of the color space in the first

Color space representation is greater than or equal to the thickness which is used for actual printing of the digital image of the color space.

The image data created as fine data, that is the digital image in the first print format is an ICC ECI color profile (International Color Consortium - color profile - European Color Initiative) assigned.

The first print format, for example, the print format PDF (Portable Document Format).

When a plurality of digital images that are created by a variety of different lithography stations, each which is for the database to be created

Print format for all lithography institutions equal to predetermined so that all digital images and are in their basic structure, in particular the first in the print format and the selected first color space representation equal thus can be processed always in the same way in a simple and cost effective manner.

In other words, that are in "standardized" form, ie in defining a fixed format provided by lithography institutions digital images.

The digital images are transmitted from the respective lithography institution in electronic form, for example by means of an electronic data carrier or via the Internet using electronic mail to the manufacturer of a product, that is, more specifically, to a server computer of the manufacturer.

Alternatively, the digital images can also be created by lithography institution in the first print format and sent to the manufacturer of a product. In this case, the digital images are in the first print format by the manufacturer of a product, even in the second print format, that is, converted to be created for the database print format.

The second print format is characterized in that contour information is coded into the present according to the second print format digital image contours may be contained. As a second print format a pixel-based print format is preferably used; Preferably, the print format EPS (Encapsulated Post Script) is employed.

An advantage of the representation of the digital image in the second print format with the digital image mapped contour information contained in the digital image contours can be seen that using the contour information from DTP data and CAD data for the respective still two-dimensional master particular at a three-dimensional animation is possible in a simple manner by means of a 3D animation program of a package, which is shown in the image. In other words this means that first a three-dimensional image of the objects contained in the digital image is created according to an embodiment of the invention using the contour information and a user is presented. The now created new three-dimensional image obtained new contour information, and is presented to a user.

This saves vividly creating a physical prototype, that is a hard proof, and the photograph of the prototype. The clear and reliable presentation of the three-dimensional body, that is in particular the three-dimensional package or three-dimensional product can thus already be in electronic form.

The second print format is characterized in accordance with an embodiment of the invention in that an additional data compression is provided with a predetermined compression factor, the compression factor is selected such that no to the human eye

Loss of quality in the displayed image can be seen.

Any digital image which is present in the second print format, first textual data can be assigned, wherein the first textual data are predetermined in their syntax.

After conversion of the digital image in the second print format, the digital image is stored in an image database. In a further step, the digital image is preferably transformed into a third print format when reading out of the image database of the second print format.

In the third print format the existing contour information usually remains intact.

According to a further embodiment of the invention the digital image of the second print format is additionally in a fourth printing format, preferably in JPEG or JPEG2000, converted and stored in the image database.

Any digital image which is present in the fourth printing format, and is stored in the image database, second textual data can be assigned, wherein the second textual data are predetermined in their syntax.

Clearly, the first textual data and the second textual data can be viewed as metadata that can be predetermined properties and characterizations,

Classifications of each product or package that represents the image, describe.

In principle, any information may be included in the first textual data, for example, the indication of the lithography institution, which has generated the digital master in the first print format, the date or the place of creation of the digital image, in the first print format.

Alternatively or additionally, other multimedia data, particularly audio data can be associated with a digital image that describe for example the product packaging or in more detail.

The third print format of the following print sizes is preferably used: • The print format PDF;

• the print format EPS;

• Print Format JPEG;

• Print Format JPEG 2000th

When using JPEG or JPEG 2000 compression standard, ie as a second print format, a compression factor has been found greater than or equal to 0.8 as sufficient, thus ensuring that the information loss is not a recognizable to the human eye quality loss leads.

The digital image in the second print format and the fourth print format may also in the syntax predetermined different second textual data profiles be associated with optional usage right information, by means of which specifies the usage rights of users on the digitized image in the second print format and the fourth print format become.

According to one embodiment of the invention, the print format is Encapsulated PostScript used with a second color space representation in the RGB color space as the second print format.

The first textual data and / or the second textual data is encoded in accordance with an embodiment of the invention according to the IPTC (International Press Telecommunications Council and standard).

In the free-encodable areas of the IPTC standards fixed, the single digital image individually verschlagwortbare data sequences are predetermined by means of its own fixed profiles.

In this way it is possible in a uniform way to assign predetermined textual data in a simple manner the data stored in a database, digital images in the second print format and compressed in a compressed print format.

In addition, each can be assigned to data stored in the image database digital image in the second print format or in the fourth print format access rights, that is an indication of whether a user has read-only, only be written or read and write access to the respective digital image.

in one embodiment of the invention further is provided on a roll concept, for example with freely definable user groups, based control of access to the database in which the digital images are stored. The access rights can be transferred electronically from another, such as a corporate program. In this case, a user has within the database immediately the same access to the archived data in the database as any other in a local computer network (Intranet) of the company's stored data.

In the image database it is now possible in a simple manner, a user in any variety, for example, in an overview display with a plurality of other digital images or as a single image representation together with the first textual data and / or the second textual data for the digital images represent user selectable.

Further, the digital images can be selected and in a third print format, according to an embodiment of the invention in a print format with a third color space representation, preferably a color space representation in the CMYK color space, generally a color space representation in a color space of the actual physical printing of the digital image is used to convert. According to one embodiment of the invention, the color space of the second color space representation of the second print format and the fourth format is greater than the pressure actually available at the pressure used and thereby color space.

In this way, a continuous electronic, multimedia processing images to be printed according to the invention starting permits from a digital image creation in a lithography institution to a professional printing in a printing house, in the intermediate formats a very simple and thus efficient and cost-effective processing and animation digital images is made possible in the form of a three-dimensional animation of the digital images or an archiving in a database.

Due to the fully automated and continuous electronic processing of digital images no unwanted information and quality loss is longer given. This ensures a particularly compared to the known procedure significantly improved color authenticity of the digital images.

Further, the implementation of a generated digital image, particularly the image of a packaging up to the actual pressure in a catalog or the creation of a package of a product is considerably reduced, so that the degree of relevance of a product catalog considerably increased with respect to the actual current range becomes.

The method is suitable not only to himself

Packing pictures, but also on every digital and analog image. Except for printing the images are prepared in other digital media (Internet, Intranet) color and quality optimized and multimedia available. An apparatus for processing at least one digitized image which is present in a first print format with a first color-space representation, has a processor which is set up such that the method steps above described are feasible.

Further, a computer program element is provided, which comprises a computer-readable storage medium on which a program is stored which enables a computer after it has been loaded into a memory of the computer to perform the steps described above for processing at least one digital image ,

On a computer readable storage medium, a computer program is also stored which enables a computer after it has been loaded into a memory of the computer to perform the method steps described above.

In the block diagram 300, a lithography institution 301 is shown in which a digital image 302 in a first printing format with a first color space representation, as explained above, is generated. The digital image 302 in the first print format is transmitted to the server computer 303 in an electronic message, for example, by electronic mail (e-mail), and there received (step 304).

In a further step (step 305) using a format conversion program, which is stored in the program memory 111, the digital image from the first print format converted into a second print format.

In an alternative embodiment, the conversion of the digital images from the first print format in the second print format can already be carried out by the respective lithography institution itself. In this case, the digital images are transferred already in the second print format present on the server computer 303 in an electronic message, for example, by electronic mail (e-mail) and received there.

Supplied by the respective lithography institution 301 digital images associated with first meta data for describing the image content.

The first metadata encoded in this embodiment according to the IPTC standard.

According to this embodiment, the second print format is the print format EPS (Encapsulated Post Script), which in particular has the property that is coded with this pixel-based print format contour information contained in the digital image 302 contours.

The contours are used in accordance with this embodiment, in order from the information contained in the digital image objects, a 3D animation of the respective packaging, i.e., to generate a three-dimensional representation of the image (block 306) and this to a user on a display unit (not shown display).

Further, second metadata describing the image content to be the digital image in the second print format assigned (step 307).

The second meta data are also encoded in this embodiment according to the IPTC standard.

In other words, it means that predetermined database fields for each of a digital image that is an image of a package, are provided, wherein the instances of the database field, that is, the respective specific information for the respective database field with respect to the respective packaging and the respective product of each are assigned to digital image. For various types there are various preset metadata profiles corresponding to the IPTC standard.

• a product description 504;

• an indication of the spatial dimension of the package 505;

• an indication of the amount of content of the product in the package 506;

• a unique product number 507;

• a manufacturer-specified internal identification ILN 508;

TM TM

• a manufacturer-internal SAP SAP -number 509;

• a short mark-packaging unit 510; • the perspective from which the digital image is a perspective indication 511, with which is indicated the packaging;

• an information profile 512, that is more optional information about the represented in the digital image product and its packaging;

• a first validity indication 513, with which the time is indicated, from which the information for the respective packaging is valid;

• a second validity indication 514, with which the time is indicated, to which the information for the respective

Packaging is valid;

• an indication 515 of the author of the specification;

• an indication 516 over the rights to the digital image 502; • a source 517, is specified with the person from whom the digital image has been received; • an indication 518, with the date of creation of the digital image is specified;

• a Erstellungsortangabe 519;

• an indication 520 of the State in which the digital image was created;

• Aufgebercode, specified with the business associated with the manufacturer of the product companies are 521;

• a field 522 for more of the digital image characteristics;

• a field 523 for the digital image name;

• an indication of size 524 with the file size of the digital image is expressed in megabytes to plausibility check; • a document format specification with which the

is document format, according to Figure 5 EPS, so Encapsulated PostScript stated.

In this context it should be noted that the IPTC standard is designed for journalism / publishing data structures, that is, actually he is incompatible with related information like Packungsmaß, weight, EAN code.

However, the invention takes place according to an automatic assignment of packing and product data for specific IPTC fields. In this context, some information in natural-language expressions are converted.

For example, a data field called "weight" is provided with which the weight of a product is specified. In IPTC context of this data field is defined as a free text field. The free text field is automatically with the content of the word: Occupied plus the corresponding data field "weight". The conversion is made so that it is reversible and human readable. This semantic, partly manually or semi-automatically generated under the control of the user or an administrator of the image metadata to the IPTC For at, generally to data with a structurally defined target format ensures that in the context of

Database usage are important object-related data, and are automatically processed. Furthermore, the picture provides a significant advantage in securing copyright aspects of database user. Also, an efficient further processing, for example, as part of a content management system, a different image database, a production database, etc. is ensured according to the invention.

The selected image data is converted addition of the second print format in a fourth printing format according to this embodiment of the invention in JPEG or JPEG2000 and stored in the image database (Step 318).

According to the JPEG standard or the JPEG 2000 standard, it is possible, the digital image in the second print format or in the fourth print format in compression according to one of these compression standards assign additional metadata.

In this embodiment, each digital image are assigned as additional metadata usage rights 310 (step 311), with which are associated in terms of the digital image the usage rights of a particular user, for example, an indication of whether the user has no right of use, only be read usage right, or all use rights has in terms of the respective digital image.

In converting the digital image from the first printing format to the second print format at the same time a compression according to the JPEG standard, or in accordance with the JPEG2000 standard with a compression factor of, for example> 0.8 when using the printing format JPEG is performed.

The compressed digital images in the database archived (step 312).

In this context that the archiving, that is, the storage of the image data and the metadata is carried out separately from each other is noted. This is based also on different forms of metadata of an object.

The storage of the data, according to this

Embodiment distributed to different sub-components of the overall system:

• The object data, in other words the actual specific file, such as the particular digital image are stored in the file system of the host computer; • the metadata, including the information as to which files are associated with the respective metadata are stored in a relational database system;

• the separation (extraction of metadata from the actual file), administration and Z the total data reunification itself is made by the application program and by decisions of the corresponding object managers, for example, the administrator of the entire system affected.

In this way it is possible, regardless of the

Image files of archived media objects, to subject the media objects a separate search mechanism.

Storing the data in the file system of the host computer in a hierarchical and abstract form that is optimized for automatic search inquiries. When storing a file visual derivatives (so called renderings) are generated also automatically which clearly provide the graphical representation, a reduced color correct representation of the object in the application interface.

The linking of the respective object with metadata controlled by the file type, and is thus dependent on this, as well as the form of presentation in the application and assigned to the users access rights.

So can get assigned to a different standard object metadata. A graphics file type JPEG can be for example a picture of a product with this associated dimensions, capacity, weight, EAN etc as

Metadata. Just as a graphic file type JPEG can also be the figure of a person - with of course different distinct metadata which are associated with this file.

According to the invention an image of the potentially encoded according to different standards metadata using predefined mapping tables. So an automatic mapping of example, product mapping information defined on journalistically oriented data fields in the IPTC context in the mapping table, for example.

By mapping in different formats encoded textual information in other required format using the mapping table to add additional information to an object much easier.

If one or more digital images are selected from the database (step 313), the digital images from the JPEG-compressed EPS format (generally the second print format) transferred to a printing machine 316 and thus to a print shop. Now, the digital image in the second printing format after downloading, for example, at the printer (for example, in the EPS format or in the JPEG format) into a digital image in the third print format, this embodiment, in a PDF format, is converted in accordance with.

In the third printing format, a third color space representation is used with a CMYK color space, which the CMYK color space is usually used as the color space for professional printing an image in a print shop. At this time, the individual machine data (for example, the so-called dot gain) was added and the actual image there is physically printed.

The one or more digital images 315 in the third print format to a print shop computer 316 and transferred thereby to a print shop and there is the actual image printed physically 317th

The 4a to 4c show a representation of a plurality of digital images 400, each representing a picture of a package of a detergent. The digital images 400 each textual data 401 are assigned.

The digital images 400, which are illustrated in the 4a, Fig. 4c and b are stored in the image database and are provided to the user in the embodiment shown in 4a to 4c manner for selection.

The Figure 5 and Figure 6 show an enlarged view of a selected digital image 500, 600 with the digital image 500, 600 associated with textual data 501, 601 after the selection of the plurality of digital images, as shown in 4a are to Fig. c shown. 6 shows to the digital image 600, illustrating another package 600, the textual data to the digital image 600, and thus the packaging associated six hundred and first

In addition, some alternatives to the embodiment described above are explained in detail:

The system can be integrated in a browser application, for example, in an application that can display data encoded according to the HTML format and process. For the detailed representation of certain graphic-oriented objects for example in EPS, TIFF, JPEG is an interactive image processing of digital graphic objects, unlike the digital images expressed provided. In this case, interactively accessed by a user using the application program on graphic portions of the media object.

Further, it may be provided that one or more portions of the image may be cut by a user and can be processed individually on. In this way it is possible only to encode a representative and most characteristic and freely selectable by the user part of an object and to transfer the user and display there, which offers a significant reduction in the bandwidth required for data transmission is achieved without the user having a must accept him for essential use restriction.

Through an instantiation of the object and a user's session, as well as the encapsulation of the user sessions from each other, each user receives a resultant of its interaction view on the corresponding object.

The encapsulation takes place on the server side. By managing instances and sessions in cache the server computer ensures that the individual actions of different users, not influence each other to actually same object, but which is temporarily stored in multiple copies in the latches to the respective processing.

The actually contradictory views of the same object due to different arrangements of different users thus affect only the respective copies, so a user can, for example, create the presentation in a room bright, but another user darker.

Interactive thus the Web client / browser with an interactive part of the program of the application program temporarily come to the meeting controlled individual view is to allow an object and directly interactively (for example, by dragging and dropping elements, function buttons, pop-ups, calculating devices for image formats) in this case, to influence opinion.

By an additionally provided storage function, the user can also be transferred individual view on his workstation "his" and thus receives a copy of the edited object. In the context of ensuring consistency of the processed objects any suitable database synchronization protocol can be used according to the invention.

Furthermore, it is provided that a user can place an order of the product is shown in the respective image, automatically. To realize this feature, one based on an email mechanism Order functionality is built into the present system, where customers or employees by means of e-mails will be informed automatically when needed depending on predefined events. Since the processing of high resolution image data is available on many employed computing systems not possible in real time, however, the user needs immediate readiness of the application program for entering data or the assignment of data to a particular file object, in an alternative embodiment of the invention it is provided that the recording process an object is divided into a plurality of subregions and the subregions are separated in time in the sequence.

With a fast and reliable type and consistency check (clearly a zero Rendering) will also enables real-time, the technical review of einzuspeichernden file for correctness and correspondence of pre-defined entry criteria.

The user is then immediately able to work interactively with the file, even can search the system file. Only the time-consuming visual representation of the object through the system

Background while users can work with the file already provided. thus it increases the quality of the data provided in the application after setting a file.

Clearly computationally intensive tasks are decoupled using the time-slice system in a multitasking system of interactive processing level in this way.

Further, there is provided optionally to store additional data other type in the database and to link and with the metadata and the image data with each other. For example, audio data or video data can be stored. The video data may be saved as a video file which contains a complete movie, but alternatively or additionally may also be provided graphically create a storyboard of the film and to store. The storyboard including a plurality of, for example 9 or 16 pictures from the video data, wherein the images characterize the video data as well as possible in a sort of summary, that is, in other words, are significant for the video data. The selection of images can be done manually or by a producer of the storyboard automatically by means of a correspondingly set selector.

In another refinement, the knowledge is taken into account that for different applications, different arrangements and filtering present in the database information is required.

For example, working with a Web browser view with colors to categorize information or to prioritize.

In a presentation form that should be suitable for printing, for example, on a laser printer, the use of color, however, is cumbersome and detrimental in most cases readability. On the other hand, arise again different distribution possibilities.

According to the invention different, dedicated image forms a data set are provided for this reason, are automatically provided as a derivative from the existing data.

In addition, in the case that the database system is coupled to a plurality of client computers via a telecommunications network such as the Internet, can be provided that the screens, generally, the data display of the client machine to be calibrated in terms of their color and brightness representation properties and be transferred only after calibration, the image data to the client computer and there is shown a user.

In this case, a client computer data display unit parameters are adjusted manually on the data display unit by a user, wherein the data display unit parameters describe the respective data display unit of a client computer.

After setting the data display unit parameters, these respective of the client computer is transferred to the responsible for data transmission server computer and stored in a cookie file.

When a digital image is requested by a client computer that takes place before data transmission by reading out the image from the database on the server side an adaptation of the image to be transmitted information to the peculiarities of the respective data display unit of the client computer. The thus modified image information is transmitted to each client computer so that a shape adapted to the respective data display unit of the respective client computer and optimized image representation, in particular color reproduction and brightness display and contrast imaging is possible.

In this way, an automated, very easy and accurate and customize provisioned digital image information in a heterogeneous communications network is made possible with very different data display units.
