DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention will be described in detail by explaining embodiments of the invention with reference to the attached drawings.

FIG. 1 is a block diagram of an example of an image printing apparatus 100 according to an embodiment of the present invention. Referring to FIG. 1, the image printing apparatus 100 according to an embodiment of the present invention includes a power supply unit 10, a storage unit 20, a paper feeder 30, a display unit 40, a printing engine 50, a connector 60, an input unit 70, and a signal processing unit 80. The power supply unit 10 supplies predetermined power to drive the image printing apparatus 100.

The storage unit 20 can be divided into a first storage unit 22, a second storage unit 24, and a third storage unit 26. For example, the first storage unit 22 can temporarily store an image file including a personal image comprising at least one person and face recognition information of the person, and the second storage unit 24 can store an individual information database according to the image file or the face recognition information. The first storage unit 22 temporarily stores data for signal processing or display, whereas the second storage unit 24 is an internal storage unit, which can store data unless an external signal is input by a user. The third storage unit 26 stores a program for driving the image printing apparatus 100.

The image file basically includes a personal image comprising at least one person and face recognition information of the person. The face recognition information may comprise geometric factors, such as a position and size of each component of a face and a distance between any two of the components of the face, e.g. feature points of the face such as eyes, nose, and mouth. A face can be recognized by matching the geometric factors with a previously stored database, or the face recognition can be performed by projecting an input facial image onto the geometric factors and extracting features by means of comparison or correlation of the input facial image with a projected object of each stored facial image. In another manner, a face can be recognized by comparing the input facial image with a template image showing the entire face and analyzing a correlation diagram according to the comparison. In addition, the face recognition information does not necessarily comprise geometric factors, and may further include information regarding learning and recognition of a neural network for a learning-type recognition method using an artificial neural network. The face recognition information can be stored in a header of the image file.

The image file can include individual information corresponding to the face recognition information or location information of the time the personal image was captured. The individual information can be directly input by the user during generation of the image file after the image is captured, or may be extracted through connection with any suitable device, such as a Personal Computer (PC), a cellular phone, or a server and stored with the image file. In the current embodiment, the individual information may comprise a name, address, e-mail address, cellular phone number, and telephone number of the person. If the individual information is included in the image file, the individual information database according to the face recognition information may not be stored in the second storage unit 24 or an external storage unit 200 to be described later. The individual information can be obtained from the image file and printed on a second side of a sheet of printing paper. This will be described in more detail when the external storage unit 200 or the signal processing unit 80 is described.

The image file may include location information, and the location information can be automatically generated using, for example, a GPS receiver during generation of the image file and included in the image file. According to another embodiment of the present invention, the location information can be directly input by the user during generation or editing of the image file. According to another embodiment of the present invention, the location information can be obtained from a PC, a cellular phone, or a server using the Internet. For example, a name of a place may be obtained from a map providing site based on latitude and longitude. The location information is information regarding an environment in which a personal image of at least one person is captured and may include a name, an address, a latitude, a longitude, and weather such as temperature and humidity, of a place and the time at which the personal image is captured. For example, the location information such as latitude, longitude may be obtained using Global Positioning System (GPS).

The paper feeder 30 feeds printing paper. The display unit 40 displays printing related information, such as a power on/off status of the image printing apparatus 100 and a printing paper existence status and can comprise a Liquid Crystal Display (LCD) or an Organic Light Emitting Diode (OLED). In particular, the display unit 40 can display an image or information to be printed on printing paper before printing is performed. The display unit 40 can be included in the image printing apparatus 100 but not limited thereto. That is, the display unit 40 may be a separate display device.

For example, the display unit 40 can display in advance a personal image to be printed on a first side of a sheet of printing paper or individual information of the person or location information to be printed on a second side of the sheet of printing paper. Furthermore, when the personal image is displayed on the display unit 40, a first icon indicating that the individual information of the person exists can be displayed with the personal image. If the first icon is selected, the display unit 40 can display the individual information corresponding to the person. According to another embodiment of the present invention, a second icon indicating that the location information exists can be displayed with the personal image on the display unit 40, and if the user selects the second icon, the location information can be displayed. The individual information or the location information can be displayed in a pop-up window. The user can select the first or second icon by means of the input unit 70, and the input unit 70 provides a selection function using various function keys or a touch screen.

If face position information is included as the face recognition information, the display unit 40 can further display a contour of a face corresponding to the face position information. According to another embodiment of the present invention, the display unit 40 can further display a map corresponding to the location information. The map corresponding to the location information can be obtained from the second storage unit 24, which is an internal storage unit, or the external storage unit 200. However, since the map is variable, it is preferable that the map corresponding to the location information be obtained from a server 220 of the external storage unit 200, such as a map providing site.

The printing engine 50 prints a personal image on a first side of a sheet of printing paper and individual information of the person or location information on a second side of the sheet of printing paper. The printing engine 50 may further print a first symbol and/or a second symbol, which indicates that the individual information or the location information has been printed, on the first side of the sheet of printing paper. The printing engine 50 may further print a contour of a face or a map associated with the individual information or the location information on the second side of the sheet of printing paper. The printing engine 50 can print the first side and then the second side or simultaneously print both sides by arranging a print head at a front side and a rear side of the printing paper, or arrange a print head on only one side of the printing paper and print both sides by rotatably feeding the printing paper.

The connector 60 is connected to the external storage unit 200. The external storage unit 200 can store an image file or an individual information database according to face recognition information. Thus, the image file or the individual information can be obtained from the external storage unit 200 via the connector 60. According to the storage unit 20, if an image file includes individual information according to face recognition information, the database may not be stored in the external storage unit 200. The connector 60 can be divided into a first communication unit 61 transmitting and receiving information to and from a storage unit 210 of the external storage unit 200, a second communication unit 62 connected to the server 220, and an interface 63 connected to a storage medium 230 to read information.

The storage unit 210 can include any of a plurality of devices in which an image file or a database is stored even if a major function of the devices is not a function of storing the image file or the database. For example, the storage unit 210 may be a digital capturing device generating and storing an image file by capturing a person and recognizing a face of the person, a PC receiving and storing the image file from the digital capturing device, or a cellular phone. The storage unit 210 can transmit the image file or individual information according to face recognition information to the image printing apparatus 100 via the first communication unit 61 using a wired method, such as cable, or a wireless method, such as Radio Frequency Identification (RFID) or Bluetooth.

The server 220 is also an example of the external storage unit 200 and may be a personal mail server or an information providing server. For example, if an image file is stored in the mail server, the image file can be read into the image printing apparatus 100 by accessing the mail server via the second communication unit 62. The individual information according to face recognition information also can be read by accessing the information providing server in which the database is stored.

In addition, the connector 60 includes the interface 63. The interface 63 is connected to the storage medium 230, such as a memory card, a Hard Disc Drive (HDD), or a Floppy Drive (FD), in which the image file or the individual information database is stored. Desired information can be read from the storage medium 230 via the interface 63.

When the icon is selected or when individual information or location information is incorrect and modified, the selection or modification can be performed by means of the input unit 70. The input unit 70 also can be used to input an external signal for operating the image printing apparatus 100. The input unit 70 may comprise buttons or a touch screen. The signal processing unit 80 controls a general operation of the image printing apparatus 100 according to the program stored in the third storage unit 26.

If first individual information according to face recognition information is included in an image file, second individual information according to the face recognition information is stored in the second storage unit 24, which is an internal storage unit, and third individual information according to the face recognition information is stored in the external storage unit 200, the signal processing unit 80 determines the latest information from among the first individual information, the second individual information, and the third individual information included or stored in the image file and extract the determined information, the second storage unit 24, and the external storage unit 200. The non-extracted information can be updated to the latest information.

The image printing apparatus 100 described above acquires individual information using face recognition information or location information included in an image file and prints the individual information or the location information on a rear side of printing paper on which a personal image is printed, helping the user to easily recall the capturing situation. Hereinafter, an example of an image printing method according to an embodiment of the present invention will now be described with reference to the attached drawings.

The image file includes a personal image including at least one person. The image file is analyzed in operation S22, and it is determined in operation S23 whether the image file includes face recognition information. If it is determined in operation S23 that the image file includes face recognition information, it is determined in operation S24 whether the image file includes first individual information corresponding to the face recognition information.

If it is determined in operation S24 that the image file includes first individual information, the first individual information is extracted in operation S25. Referring to FIG. 3B, it is determined in operation S26 whether an internal storage unit includes an individual information DB according to the face recognition information. The internal storage unit comprises a storage unit installed in the image printing apparatus. If it is determined in operation S26 that the internal storage unit includes an individual information DB, second individual information corresponding to the face recognition information is extracted from the individual information DB in operation S27.

It is determined in operation S28 whether an external storage unit is connected to the image printing apparatus. The external storage unit is disposed outside the image printing apparatus and may be a PC, a cellular phone, or a server, which can store the individual information DB. If it is determined in operation S28 that the external storage unit is connected to the image printing apparatus, it is determined in operation S29 whether the external storage unit includes the individual information DB, and if it is determined in operation S29 that the external storage unit includes the individual information DB, third individual information corresponding to the face recognition information is extracted from the individual information DB in operation S30.

The latest individual information is determined among the first individual information, the second individual information, and the third individual information and the latest individual information is extracted in operation S31. The non-extracted individual information is updated in operation S32, and the personal image is printed on a first side of the sheet of printing paper and the extracted, i.e. latest, individual information is printed on a second side of the sheet of printing paper in operation S33.

After extracting the first individual information and the second individual information in operations S25 and S27, if the external storage unit is not connected or the external storage unit does not include the individual information DB, the latest individual information is determined among the first individual information and the second individual information and extracted in operation S31. The non-extracted individual information is updated in operation S32, and the personal image is printed on a first side of the sheet of printing paper and the selected (e.g., the latest) individual information is printed on a second side of the sheet of printing paper in operation S33.

Referring to FIG. 3A, if it is determined in operation S24 that the image file does not include first individual information, it is determined in operation S34 whether the internal storage unit includes the individual information DB. Referring to FIG. 3C, if it is determined in operation S34 that the internal storage unit includes the individual information DB, the second individual information is extracted from the DB in operation S35.

It is determined in operation S36 whether an external storage unit is connected to the image printing apparatus. If it is determined in operation S36 that the external storage unit is connected to the image printing apparatus, it is determined in operation S37 whether the external storage unit includes the individual information DB, and if it is determined in operation S37 that the external storage unit includes the individual information DB, the third individual information is extracted from the individual information DB in operation S38. Referring to FIG. 3B, the latest individual information is determined among the second individual information and the third individual information and extracted in operation S31. The non-extracted individual information is updated in operation S32, and the personal image is printed on the first side of the sheet of printing paper and the extracted (e.g, the latest) individual information is printed on the second side of the sheet of printing paper in operation S33. After extracting the second individual information from the internal storage unit, since the image file does not include the first individual information and the internal storage unit includes the individual information DB, if the external storage unit is not connected or the external storage unit does not include the individual information DB, the personal image is printed on the first side of the sheet of printing paper and the second individual information is printed on the second side of the sheet of printing paper in operation S33.

Referring to FIG. 3A, if the image file does not include the first individual information in and the internal storage unit does not include the individual information DB, it is determined in operation S39 whether an external storage unit is connected to the image printing apparatus. Referring to FIGS. 3A and 3C, if it is determined in operation S39 that the external storage unit is connected to the image printing apparatus, it is determined in operation S40 whether the external storage unit includes the individual information DB, and if it is determined in operation S40 that the external storage unit includes the individual information DB, the third individual information is extracted from the DB in operation S41. Referring to FIG. 3B, the personal image is printed on the first side of the sheet of printing paper and the third individual information is printed on the second side of the sheet of printing paper in operation S33. When the image file does not include the first individual information and the internal storage unit does not include the individual information DB if an external storage unit is not connected or the external storage unit does not include the individual information DB, the user can directly input individual information in operation S42.

Referring to FIGS. 3A and 3C, if it is determined in operation S23 that the face recognition information does not exist, the user can directly input individual information in operation S42. The personal image is printed on the first side of the sheet of printing paper and the input individual information is printed on the second side of the sheet of printing paper in operation S33.

Referring to FIGS. 3A and 3B, after extracting the first individual information in operation S25, if it is determined in operation S26 that the internal storage unit does not include the individual information DB, it is determined in operation S43 whether an external storage unit is connected. If it is determined in operation S43 that an external storage unit is connected, it is determined in operation S44 whether the external storage unit includes the individual information DB, and if it is determined in operation S44 that the external storage unit includes the individual information DB, the third individual information is extracted from the DB in operation S45. Thus, the latest individual information is determined among the first individual information and the third individual information and extracted in operation S31. The non-extracted individual information is updated in operation S32, and the personal image is printed on the first side of the sheet of printing paper and the extracted (e.g., the latest) individual information is printed on the second side of the sheet of printing paper in operation S33.

Referring to FIGS. 3A and 3B, after extracting the first individual information in operation S25, if it is determined in operation S26 that the internal storage unit does not include the individual information DB, and if an external storage unit is not connected or the external storage unit does not include the individual information DB, only the first individual information is extracted as a result. Thus, the personal image is printed on the first side of the sheet of printing paper and the first individual information is printed on the second side of the sheet of printing paper in operation S33.

In the embodiment described above, since individual information can be obtained from at least one of an image file, an internal storage unit, and an external storage unit, correct individual information can be printed by extracting the latest individual information by comparing the individual information and updating the non-extracted individual information. Thus, a person in a printed matter can be easily recalled, and since the latest individual information is printed on a rear side of printing paper, correct information can be obtained in order to show or transmit the printed matter to the person in the future.

The kiosk 300 is a device for printing a photograph easily and any time, and by applying the image printing method according to an embodiment of the present invention to the kiosk 300, information regarding captured image(s) or information regarding a capturing place can be easily recalled by means of a rear side of the photograph.

As described above, according to the embodiments of the present invention, by printing a personal image on a first side of a sheet of printing paper and individual information or location information on a second side of the sheet of printing paper using an image file including the personal image, face recognition information, and the individual information according to the face recognition information or location information, the memory of the time at which the image of the person was captured can be easily recalled with only the printed matter. For example, if a long time elapses after an image of a plurality of people is captured, information regarding the people or the memory of the time at which the image of the people was captured is not clearly recalled; however, by printing a personal image of the people on a first side of a sheet of printing paper and individual information of the people or location information of the capturing time, the memory of the capturing time can be maintained.

In addition, an image file including a personal image and face recognition information may further include individual information according to the face recognition information, or the individual information according to the face recognition information is stored in a database and stored in an internal storage unit of an image printing apparatus or an external storage unit, such as a storage device such as a PC or a cellular phone, a server, or a storage medium such as a memory card, and then the individual information can be obtained from the internal storage unit or the external storage unit. The latest individual information can be determined and selected, and non-selected individual information can be updated. Thus, by printing correct individual information on a second side of a sheet of printing paper, latest information of captured images can be provided.

In addition, an image, individual information, or location information to be printed on a first or second side of a sheet of printing paper can be confirmed before printing is performed. Thus, it can be determined whether an image or information to be printed is correct, and if it is determined that the image or information to be printed is incorrect, the image, the individual information, or the location information can be modified before printing is performed. For example, if a personal image to be printed on the first side of the sheet of printing paper is displayed as a preview, at least one of an icon indicating the existence of the individual information and the location information can be further displayed, and by selecting the icon, at least one of the individual information and the location information can be confirmed or modified before the printing is performed.

In addition, by printing the personal image and a symbol, which indicates that at least one of the individual information and the location information was printed on the second side of the sheet of printing paper, on the first side of the sheet of printing paper, it can be determined by checking only the first side that the individual information exists. Furthermore, at least one of the individual information and the location information can be obtained by viewing the second side of the printed matter.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by one of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
