## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method and a system for printing images photographed by a portable communication apparatus provided with an imaging device.
2. Background Arts
A mobile phone provided with a camera, having an imaging function as well as functions for voice communication and data communication such as sending and receiving e-mail, has been popular recently. Such mobile phone with the camera may store images photographed by the imaging device as image data. For example, Japanese Patent Laid-Open Publication Number 2002-132923 discloses a method for printing image data, stored in the mobile phone with the camera, by sending them to a printing device via telecommunication network and printing them by means of the printing device.
Concerning the speed and the cost for the communication, however, it is not preferable to send image data via telecommunication network. As an example of other methods, a print system disclosed in Japanese Patent Laid-Open Publication Number 2001-309106 prints images by using a print unit of stand-alone type. In order to print images in this print unit, a user directly sends image data stored in the mobile phone with the camera to a printer, incorporated in the print unit, via wire or infrared communication and operates the printer to print images.
Nevertheless, that print system has a problem of increasing the size and the cost of the print unit, since a charging system and a cash insertion equipment must be mounted within a print unit along with devices for receiving image data and for printing them. Furthermore, the user must prepare cash in advance, as the print system requires it to be inserted in every printing.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a method and a system for printing images being convenient for a user, with reducing cost for a print unit.
In order to achieve the above object, an image print system of the present invention comprises a portable communication apparatus for communicating via telecommunication line by a communicating device and for storing images photographed by an imaging device as image data, a charging server connected to the portable communication apparatus via the telecommunication line for charging the portable communication apparatus for telecommunication charge based on the communicating duration or volume of communicated data, and a print unit for reading out the image data from the portable communication apparatus by connecting to the portable communication apparatus by means of a connecting device, printing images on recording paper based on the image data, and controlling the communicating device of the portable communication apparatus to communicate/cut off the communication with the charging server.
In order to achieve the above object, an image printing method of the present invention is as follows. A print server reads the image data, stored in the portable communication apparatus, into itself when the portable communication apparatus is connected to the print server. Then, the print server controls the portable communication apparatus to connect with charging server via telecommunication line and displays the images on a display according to the image data read into the print server. A user arbitrarily selects images for printing among the images displayed on the display and specifies the number of prints of each selected image. Subsequently, when the user operates a print command, the print server drives a printer in response to the print command to print the selected images as many as each specified number of prints. When printing is completed, the print server controls the portable communication apparatus to disconnect from the charging server. Based on connecting duration with the portable communication apparatus, the charging server charges the portable communication apparatus for telecommunication charge.
According to the method and the system for printing images of the present invention, since the printing charge is charged to the portable communication apparatus as telecommunication charge, there is no need for the print unit to collect cash as the printing charge from the user and for the user to prepare cash in advance for the printing. Thus, the print unit does not need either a charging system or a cash insertion equipment to be incorporated therein, and that enables the print unit to reduce its size and the cost.
Furthermore, the user tends to take time to select the images for printing carefully in the conventional method and system for printing, as the printing charge is based on the number of prints. However, since the method and the system for printing image of the present invention may charge the telecommunication charge based on the time for operation including selecting the images, the user tends to operate the print unit quickly for trying to save time in an attempt to be charged less, and it may speed up the rotation of customers and collect more of them efficiently.

PREFERRED EMBODIMENTS OF THE INVENTION
An image print system of the present invention shown in FIG. 1 is administrated by a mobile phone company, which operates a communication system for a mobile phone with a camera. A mobile phone with a camera (referred to as the mobile phone hereinafter) 10 is provided with an imaging part 13. When a taking button (not shown) is pushed, a subject image taken through a taking lens 15 is captured by a CCD 17 as image pickup signals. The image pickup signals are converted into image data and stored in a memory 19.
The mobile phone 10 is also provided with a communication part 20 for sending and receiving various data and is connected to a communication network 22 of a telecommunication line administrated by the mobile phone company, via an antenna 21. Via the communication network 22, the mobile phone 10 is connected to external devices such as another mobile phone 27 or a personal computer. The mobile phone 10 may communicate with the external devices by voice through a microphone 23 and a speaker 24 or by sending and receiving e-mail and the image data stored in the memory 19.
The mobile phone 10 is also provided with a communication terminal 25 connected to the communication part 20. The communication terminal 25 is exposed when a bottom lid of the mobile phone 10 is opened, for example. The communication terminal 25 may send the image data to external devices such as a personal computer and an adapter device 35 of a print unit 30, which is described later, by being connected to them.
The communication network 22 has a plurality of base stations for relaying data communication operated by the communication part 20 between the mobile phone 10 and other devices. The communication network 22 is also connected to a charging server 26 that calculates telecommunication charge based on the volume of communication of the mobile phone 10 such as duration of voice communication and volume of communicated data by e-mail with referring to a table, in which user IDs (phone number, for example) and their telecommunication charges are related each other. Since the charging server 26 is provided with a predetermined phone number, it is possible to communicate with the charging server 26 by calling the phone number.
The print unit 30 comprises a printer 33 and the adapter device 35, which is a print server, and both of them are connected to each other by a connecting line such as a USB cable or by wireless. Such print units 30 are placed at station kiosks, restaurants, convenience stores, game halls, and the like.
For example, an inkjet printer or a thermal printer is applied as the printer 33. The printer 33 is driven by the adapter device 35 and prints the images on recording paper based on the image data sent from the adapter device 35. The adapter device 35 is provided with a connecter 39 that is connectable with the communication terminal 25 of the mobile phone 10. The image data may be read out from the mobile phone 10 and sent to the printer 33 when the communication terminal 25 is connected with the connector 39.
The adapter device 35 is also provided with a liquid crystal display (LCD) 41 and an operating section 48, which is connected to the controlling section 49 and comprises a cursor key 43, a determination button 45, and a print button 47. The controlling section 49 controls the adapter device 35, the printer 33, and the mobile phone 10 based on a control program stored in a ROM 51. When the controlling section 49 detects that the mobile phone 10 is connected with the connector 39, it controls the mobile phone 10.
When the mobile phone 10 is connected to the connector 39, the controlling section 49 reads the image data, stored in the memory 19 of the mobile phone 10, and stores them in a first memory 53 within the controlling section 49 of the adapter device 35. Subsequently, the controlling section 49 drives the communication part 20 of the mobile phone 10 to start communicate with the charging server 26 and the LCD 41 to display a print image selection screen.
FIG. 2 shows the print image selection screen displaying thumbnail images 54 stored in the first memory 53 and number bars 55 disposed next to each of the thumbnail images 54 for showing the number of prints of each thumbnail image 54. Each of the number bars 55 includes boxes 56 indicating the number of prints. One of the boxes 56 is framed by a cursor 57, which is shown as a thick frame in FIG. 2 and moves among the boxes 56 as the cursor key 43 is operated. When the determination button 45 is pushed, the number in the box 56 framed by the cursor 57 and the image 54, corresponding to the number bar 55 having the framed box 56, are stored in a second memory 59.
The print button 47 is operated to print the images stored in the second memory 59. When the print button 47 is operated, the controlling section 49 drives the printer 33 to start printing the images stored in the second memory 59. After the images stored in the second memory 59 are printed as many as each specified number of prints, also stored in the second memory 59, the controlling section 49 cuts off the communication with the charging server 26. At this point, the controlling section 49 displays a printing completion screen on the LCD 41 to inform that printing is completed, as shown in FIG. 3.
An operation of the above embodiment of the present invention is explained now with using a flow chart shown in FIG. 4. In order to print the image data photographed by the mobile phone 10, a user needs to connect the communication terminal 25 of the mobile phone 10 to the connector 39 of the print unit 30. Thereby, the image data stored in the mobile phone 10 is read out by the adapter device 35.
Subsequently, the mobile phone 10 starts to communicate with the charging server 26, and the LCD 41 displays the print image selection screen. The user operates the cursor key 43 for shifting the cursor 57 and pushes the determination button 45 for determining images for printing and the number of prints of each image. Then, printing is started by pushing the print button 47. After the printing of the selected images as many as each specified number of prints is completed, the communication between the mobile phone 10 and the charging server 26 is cut off, and the printing completion screen shown in FIG. 3, informing that printing is completed, is displayed on the LCD 41.
Note that the present invention is not limited in the above embodiment in which the communication from the mobile phone 10 to the charging server 26 is started after the print unit 30 reads out the image data from the mobile phone 10, and is cut off after the printing is completed. For example, it is possible to arrange that the mobile phone 10 starts communication with the charging server 26 when printing is started or after the mobile phone 10 is connected to the connector 34. In addition, it is also possible to charge the telecommunication charge based on the number of prints of images after completing printing the images, though the telecommunication charge is based on the time from selecting the print images to completing printing the selected images, in the above embodiment.
Note that the type of communication from the mobile phone 10 to the charging server 26 may be either voice communication or data communication such as e-mail, for example. In case of that the telecommunication charge is charged by voice communication based on the number of prints, the mobile phone 10 calls the charging server 26 for the duration corresponding to the number of prints such that the telecommunication charge is charged as duration of call. In case of that the telecommunication charge is charged by data communication, data having a volume corresponding to the number of prints is sent to the charging server 26 by the mobile phone 10 such that the telecommunication charge is based on the volume of the data.
Note that it is also possible to arrange for the mobile phone 10 to send data of the number of prints to the charging server 26 such that the charging server 26 calculates the telecommunication charge based on the data of print number. Thereby, it may minimize the duration of the communication between the charging server 26 and the mobile phone 10.
Note that it is also possible for the user to select the print images within the mobile phone 10, though the user selects the images by the adapter device 35 in the above embodiment. In this case, for example, the user selects the print images within the mobile phone 10, and then sends the selected images from the mobile phone 10 to the adapter device 35 by connecting them each other. Then, the adapter device 35 starts communication from the mobile phone 10 to the charging server 26 and prints the selected images simultaneously. When printing is completed, the adapter device 35 cuts off the communication between the mobile phone 10 and the charging server 26. This is an efficient way, as only the images for printing are sent to the adapter 35.
Though the adapter device 35 controls the mobile phone 10 to communicate with the charging server 26 in the above embodiment, note that it is also possible to provide the adapter device 35 with a communication part 60 that is able to communicate with the charging server 26, as shown in FIG. 5. In this case, the adapter device 35 gains an ID data such as phone number, which is unique to the mobile phone 10, when the mobile phone 10 is connected to the connector 39. The adapter device 35 sends data of the number of prints and the ID data to the charging server 26 after printing is completed, such that the telecommunication charge is charged based on the data of the number of prints to the mobile phone 10. Otherwise, it is also possible that the user operates the mobile phone 10 to communicate with the charging server 26 and that printing is executed only when the communication between the mobile phone 10 and the charging server 26 is detected by the adapter device 35.
Note that, though the mobile phone with the camera is applied as the portable communication apparatus in the above embodiment, other portable communication apparatus such as PDA (Personal Digital Assistance), for example, may be also applied to the present invention.
Although the present invention has been described with respect to the preferred embodiments, the present invention is not to be limited to the above embodiments but, on the contrary, various modifications will be possible to those skilled in the art without departing from the scope of claims appended hereto.
