## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the priority of Korean Patent Application No. 2004-34382, filed on May 14, 2004 and 2004-58847, filed on Jul. 27, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety and by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present general inventive concept relates to a printer, and more particularly, to an image reprinting apparatus and method.
2. Description of the Related Art
A conventional method of printing an image using a photoprinter is as follows. A photoprinter reads a memory unit where an original image is stored and retrieves the original image. The original image is displayed on a display, and a user processes the original image into a desired image. For example, a user may adjust the contrast or brightness of the original image, enlarge, reduce, or move the original image, or change the tone of the original image while looking at the original image on the display. Once the original image is processed into an image desired by the user, the desired image is printed.
After a certain period of time, when the user desires to re-print the desired image that has already been printed, the user must reconnect the memory unit where the original image is stored to the photoprinter, retrieve the original image, and process the original image into the desired image again.
However, it is difficult to process the original image into the desired image exactly as it was printed the first time. Further, if complicated image-processing was involved previously, it takes a lot of time and effort for the user to produce the same image.
SUMMARY OF THE INVENTION
The present general inventive concept provides an image reprinting apparatus and method of a printer, in which it is possible to store information regarding the processing of an image and display the image as it was processed previously when a user desires to reprint an image that has been printed before, thereby enabling the user to reprint the image without reprocessing the image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
FIG. 1 is a block diagram of a photoprinter including an image-reprinting apparatus according to an embodiment of the present general inventive concept. Referring to FIG. 1, the photoprinter includes a CPU 10, a memory unit 20, a printing unit 30, a PC interface 40, an image storage medium interface 50, an operating panel (OPE) 60, a display 70, and an image storage medium 80.
The CPU 10 controls the photoprinter according to set programs. The memory unit 20 stores operation programs and general control programs of the CPU 10 as well as data created by the CPU 10 as a result of executing programs. The printing unit 30 prints data stored in the image storage medium 80 or data transmitted to a printer driver 110 of a host PC 100.
The PC interface 40 transmits data in the host PC 100 to the printing unit 30 using the printer driver 110 such that the printing unit 30 can print the data. The OPE 60 includes a plurality of keys. When a key is pressed, the OPE 60 transmits data related to the key to the CPU 10. The display 80 receives an image and displays the image on an LCD at the command of the CPU 10.
The image storage medium interface 50 reads data stored in the image storage medium 80 and transmits the data to the display 70 at the command of the CPU 10. In addition, the image storage medium interface 50 reads an image from the image storage medium 80 and transmits the image to the printing unit 30.
FIG. 2 is a block diagram of an image-reprinting apparatus according to an embodiment of the present general inventive concept. The image-reprinting apparatus includes an image-processing information storage unit 200, a print history search unit 210, a display unit 220, an image-printing unit 230, and a print determiner 240. The image-reprinting apparatus may further include a user interface 260 and an image-processing journal output unit 270.
The image-processing information storage unit 200 stores information regarding the processing of an image when the image is processed and printed. As illustrated in FIG. 3, the image-processing information storage unit 200 may include an image index unit 300 and an image-processing information list 320. The image index unit 300 indexes image-processing information. The image-processing information list 320 is linked to each of the indexes of the image index unit 300 and stores image-processing information.
FIG. 4 illustrates in detail and example of an image index unit 300 and an image-processing information list 320 illustrated in FIG. 3. Referring to FIG. 4, an image index unit 400 stores a list of first through Nth image-processing information indexes. An image-processing information list 420 includes specific image file information and image-processing information for each index. The image file information may include information needed to identify an image file, such as a filename, a file generation date, and a file size. The image-processing information may include resolution, information regarding a selected frame, image enlargement/reduction, and the contrast, brightness and position of an image. A set value of the image-processing information can be changed, and the changed set value can be stored in the image-processing information storage unit 200. Therefore, the image-processing information storage unit 200 can store image-reprocessing information when an image is reprocessed and printed.
When an image is input, the print history search unit 210 (FIG. 2) searches the image-processing information storage unit 200 to determine whether the image has been printed before. The image can be input by reading the image from the image storage medium 250.
If the print history search unit 210 determines that the image has been printed before, the display unit 220 processes the image using previous image-processing information and displays the processed image.
The print determiner 240 determines whether a user desires to print the image as displayed on the display unit 220.
The user interface 260 provides a user with an image-processing journal output menu stored in the image-processing information storage unit 200. The image-processing journal includes the image file information and the image-processing information.
Referring to FIG. 9, the output menu of the user interface 260 may include at least two of a “Display” option to display the image-processing journal, a “Print” option to print the image-processing journal, and a “Create File” option to create a file for the image-processing journal.
The image-processing journal output unit 270 outputs an image-processing journal according to an output option selected by a user in the user interface 260. In other words, if a user selects the “Display” option, the image-processing journal output unit 270 displays the image-processing journal. If the user selects the “Print” option, the image-processing journal output unit 270 prints the image-processing journal. If the user selects the “Create File” option, the image-processing journal output unit 270 creates a file for the image-processing journal.
The image-printing unit 230 prints an image based on information regarding the previous processing of the image if a user chooses to reprint the image through the print determiner 240.
FIG. 5 is a flowchart illustrating a method of reprinting an image using a printer, according to an embodiment of the present general inventive concept. The operation of the image-reprinting apparatus included in the photoprinter and the method of printing an image will now be described.
An image-processing information storage unit 200 in which image-processing information is stored is prepared (operation 500). The image-processing information storage unit 200 can be prepared according to a method illustrated in FIG. 6. Referring to FIG. 6, when a user selects an image to process (operation 600), the image is displayed on a screen (operation 610). While looking at the image displayed on the screen, the user inputs desired image-processing information (operation 620). Then, the image is processed based on the image-processing information input by the user (operation 630). When the image is processed, the processed image is displayed. If the user desires to print the processed image (operation 640), the processed image is printed (operation 650). Then, the image-processing information is stored in the image-processing information storage unit (operation 660).
If the user desires to process the processed image again (operation 640), operation 620 is re-performed. That is, the user inputs new image-processing information. When the processed image is reprocessed, image-reprocessing information can be stored. In other words, after an image is processed, the processed image is printed and displayed based on stored image-processing information. Then, when the processed image is reprocessed, image-reprocessing information can be stored.
FIG. 7 illustrates results of image processing. Specifically, FIG. 7A is an image selected by a user. FIGS. 7B and 7C are images obtained as a result of image-processing information, i.e., image enlargement/movement, input by the user.
Referring back to FIG. 5, while the image-processing information storage unit 200 is prepared, when an image is input (operation 510), for example, when an image is input from an image storage medium 250, the image-processing information is read from the image processing information storage unit to determine whether the image has been printed before (operation 520). The image storage medium 250 may be a recording medium, such as a memory card or a flash memory, on which images can be recorded. If the image was printed before (operation 530), the image is processed based on previous image-processing information and displayed (operation 540). While viewing the displayed image, the user decides whether to print the displayed image or process the displayed image (operation 550).
If the user decides to print the displayed image, the displayed image is printed (operation 560), and the image-processing information is added to a print history (operation 570). If the user decides to process the displayed image, the user inputs image-processing information in operation 620 (FIG. 6) and reprocesses the displayed image. When the reprocessed image is displayed and printed, reprocessing information regarding the reprocessed image is stored in the image-processing information storage unit 200. Whether the user desires to print the displayed image may be determined before printing the displayed image.
If the image has not been printed before (operation 530), the user inputs image-processing information (operation 620 of FIG. 6). Then, the image is processed based on the image-processing information.
FIG. 8 is a flowchart illustrating a process of outputting the image-processing journal. Referring to FIG. 8, if the image-processing journal output menu is provided by the user interface 260 (operation 800), the user selects an output option (operation 810). As illustrated in FIG. 9, the output menu includes the “Display” option, the “Print” option, and the “Create File” option.
If the user selects the “Display” option, the image-processing journal output unit 270 displays the image-processing journal (operation 820). If the user selects the “Print” option, the image-processing journal output unit 270 prints the image-processing journal (operation 830). FIG. 10 illustrates an example of the image-processing journal. If the user selects the “Create File” option, the image-processing journal output unit 270 creates a file for the image-processing journal (operation 840).
The image reprinting apparatus and method according to various embodiments of the present general inventive concept may be included in and used by a printer, and preferably, a photoprinter. In addition, the reprinting apparatus can be included in a host computer that is connected to the printer.
The present general inventive concept can also be implemented as computer-readable code on a computer-readable recording medium. The computer-readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices.
In an image reprinting apparatus and method of a printer according to various embodiments of the present general inventive concept, information regarding the processing of an image is stored. When a user desires to reprint an image that has been printed before, the image is displayed as it was processed previously. Therefore, the user can reprint the image without reprocessing the image, which enhances user convenience.
Further, a user can view an image-processing journal displayed on an LCD or printed on a sheet of paper. Hence, there is no need for a user to remember items that the user has processed before. Moreover, when an image-processing setting is incorrect, it can be corrected easily by looking at the image-processing journal, which also enhances user convenience.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
