DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present embodiments of the present invention, 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 invention by referring to the figures.

FIG. 1 is a flowchart illustrating a method of printing full images using a device according to an embodiment of the present invention. As shown in FIG. 1, print target information is determined according to transmission conditions between the device and an image forming device in response to a request of the device, and the determined print target information is transmitted to the image forming device in operation 10. The transmission conditions include a transmission rate of a transfer protocol, a data size of selected contents, and the number of the selected contents. The transfer protocol may be one of wired protocols (i.e., a universal serial bus (USB) protocol), and of wireless protocols (i.e., a Bluetooth protocol and a wireless USB (WUSB) protocol. The transmission rate depends on the type of transfer protocol used. The data size of the selected contents indicates the size value obtained by summing a data size of each of the selected contents. The number of the selected contents indicates the number of the files of the selected contents. The print target information may be a list of contents, thumbnail images, and full images. Once the determined print target information is transmitted to the image forming device in operation 10, the selected contents are printed in operation 12 which will be discussed in greater detail below.

FIG. 2 is a flowchart illustrating operation 10 of FIG. 1, according to an embodiment of the present invention. As shown in FIG. 2, in operation 30, a transfer protocol between the device and the image forming device is determined. In addition, the particular contents to be transmitted to the image forming device are also determined. If various transfer protocols to transmit the contents exist, a transfer protocol having a relatively high characteristic transmission rate is determined to be the protocol to be used. In addition, the transfer protocol can be determined with consideration given as to whether the image forming device is able to print the contents by displaying whether the contents to be transmitted may be printed by the image forming device.

In operation 32, print target information is determined according to transmission conditions. Table 1 illustrates a lookup table used to determine print target information according to transmission conditions.

	TABLE 1
	Data size of contents [in MB]
	0 to 1	1 to 3	3 or more
Transmission	0 to 1	Full image	Full image	Thumbnail
rate of transfer				image
protocol [in	1 to 2	Full image	Thumbnail image	List
minutes]	2 or more	Thumbnail	List	List
		image

For example, among the transmission conditions, when the data size of contents is less than 3 MB and the transmission rate of a transfer protocol is less than 1 minute, or when the data size of contents is less than 1 MB and the transmission rate of a transfer protocol is less than 2 minutes, the full image format to transmit full images of contents is determined as the print target information. When the data size of contents is less than 1 MB and the transmission rate of a transfer protocol is greater than 2 minutes, when the data size of contents is between 1 MB and 3 MB and the transmission rate of a transfer protocol is between 1 minute and 2 minutes, or when the data size of contents is greater than 3 MB and the transmission rate of a transfer protocol is less than 1 minute, the thumbnail image format to transmit thumbnail images is determined as the print target information. Lastly, when the data size of contents is greater than 3 MB and the transmission rate of a transfer protocol is greater than 1 minute, or when the data size of contents is greater than 1 MB and the transmission rate of a transfer protocol is greater than 2 minutes, the list format to transmit a list of contents is determined as the print target information.

Although Table 1 illustrates that print target information is determined using the data size of contents and a transmission rate of a transfer protocol, print target information may be determined using the number of contents files as the transmission conditions. That is, print target information may be determined using a lookup table that comprises a combination of the number of contents and transfer protocols or a combination of the number of contents and the data size of the contents.

In operation 34, a list of contents or thumbnail images is created. If the list format has been determined as the print target information in operation 32, a list of contents to be transmitted is created in operation 34. If the thumbnail image format has been determined as the print target information in operation 32, thumbnail images are created by reducing full images of contents to be transmitted into thumbnails of those images in operation 34.

In operation 36, according to the determined print target information, the contents determined for transmission are transmitted to the image forming device. For example, if the list format has been determined for use with the print target information, a list of the contents determined for transmission is transmitted to the image forming device, if the thumbnail image format has been determined for use with the print target information, thumbnail images of the contents determined for transmission are transmitted to the image forming device, and if the full image format has been determined for use with the print target information, full images of the contents determined for transmission are transmitted to the image forming device.

Referring back to FIG. 1, as noted above, in operation 12, contents selected from the transmitted contents are then printed.

FIG. 3 is a flowchart illustrating operation 12 of FIG. 1, according to an embodiment of the present invention. As shown in FIG. 3, in operation 50, the contents transmitted from the device are displayed in correspondence with the determined print target information. That is, if the list format has been determined for use with the print target information, a list of the contents is displayed, and if the thumbnail image format has been determined for use with the print target information, thumbnail images of the contents are displayed, and if the full image format has been determined for use with the print target information, full images of the contents are displayed. When the contents are displayed, whether the transmitted contents are printable may be displayed.

In operation 52, contents to be printed are determined from the displayed contents. That is, the contents selected by a user from the contents displayed on the image forming device are determined to be contents to be printed. In operation 54, requests for the determined contents are made to the device, and, in response, the requested contents are received from the device and printed. If the displayed contents are either the list or the thumbnail images, a request for the contents determined for printing is made to the device. If the requested contents are received from the device in response, the received contents are printed using a printing engine. If the displayed contents are full images, the contents determined for printing are directly printed.

FIG. 4 is a flowchart illustrating operation 12 of FIG. 1, according to another embodiment of the present invention. As shown in FIG. 4, in operation 70, the image forming device senses the print target information of the transmitted contents. If the sensed print target information is formatted as a list, the image forming device displays a list of the contents transmitted in the list format in operation 72. In operation 74, a list to be printed is determined from the displayed list. That is, if the user selects a list of contents to be printed from the displayed list, the selected list is determined as the list of contents to be printed. In operation 76, the image forming device sends a request to the device for the thumbnail images or the full images corresponding to the determined list. In operation 78, the device determines whether the requested contents are thumbnail images or full images.

If thumbnail images have been requested from the device, the image forming device receives the requested thumbnail images from the device in operation 80. If full images have been requested from the device, the image forming device receives the requested full images from the device in operation 82.

If the sensed print target information is formatted as thumbnail images in operation 70, the image forming device displays thumbnail images of the contents transmitted in the thumbnail image format in operation 84. In addition, after operation 80, the image forming device displays the thumbnail images received from the device in operation 84.

In operation 86, thumbnail images to be printed are determined from the displayed thumbnail images. In operation 88, the image forming device sends a request to the device for full images corresponding to the determined thumbnail images. In operation 90, the image forming device receives the requested full images from the device in response.

If the sensed print target information is formatted as full images in operation 70, the image forming device displays full images of the contents transmitted in the full image format in operation 92. In addition, after operation 82, the image forming device displays the full images that were received from the device in operation 92.

In operation 94, full images to be printed are determined from the displayed full images. In operation 96, the full images to be printed are edited using an image editing application. In operation 98, the edited full images are printed.

FIG. 5 is a signaling diagram illustrating a process of exchanging information between a device and an image forming device according to an embodiment of the present invention. When the device transmits a signal as part of a search for an image forming device, the image forming device, which is being searched for, responsively transmits a response signal to the device. The device then checks a transmission rate of a transfer protocol for data transmission with the image forming device and determines print target information of contents to be printed according to the checked transmission conditions. The device then transmits a list, thumbnail images, or full images to the image forming device according to the determined print target information. If a list is transmitted, the image forming device displays the transmitted list and requests the device for thumbnail images or full images corresponding to a determined list. If thumbnail images are requested, the device transmits the requested thumbnail images to the image forming device. The image forming device displays the transmitted thumbnail images and requests the device for full images corresponding to determined thumbnail images. The device transmits the requested full images to the image forming device. The image forming device displays the transmitted full images and edits a layout of the determined full images. The image forming device then prints the edited full images.

The embodiments of the present invention may be written as codes/instructions/programs and may be implemented in general-use digital computers that execute the codes/instructions/programs using a computer readable recording medium. Examples of the computer readable recording medium include magnetic storage media (e.g., ROM, floppy disks, hard disks, etc.), optical recording media (e.g., CD-ROMs, or DVDs), and storage media such as carrier waves (e.g., transmission through the Internet). The computer readable recording medium may also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. Also, functional programs, codes, and code segments to accomplish the present invention may be easily construed by programmers skilled in the art to which the present invention pertains.

FIG. 6 is a block diagram of a system to print full images using a device according to an embodiment of the present invention. As shown in FIG. 6, the system includes a device 100 and an image forming device 200.

The device 100 determines print target information of contents according to transmission conditions and outputs at least one set of contents according to the determined print target information. To this end, the device 100 includes a first user interface unit 110, a print target information determiner 120, a content processing unit 130, and a first data interface unit 140. The first user interface unit 110 determines a transfer protocol between the device 100 and the image forming device 200, determines contents to be transmitted to the image forming device 200, and outputs the determined result to the print target information determiner 120.

When various transfer protocols used to transmit contents exist, the first user interface unit 110 makes a determination of a transfer protocol to be used based on which available transfer protocol has a relatively high transmission rate. In addition, the first user interface unit 110 makes a determination of a transfer protocol to be used based on consideration of whether the image forming device 200 is able to print contents when the transfer protocol is determined. To do this, the first user interface unit 110 displays whether the image forming device 200 is able to print the contents to be transmitted. When the contents to be transmitted to the image forming device 200 are determined, the first user interface unit 110 displays icons replacing contents which cannot be supported by the image forming device 200.

The print target information determiner 120 determines print target information according to transmission conditions that indicate a transmission rate of the determined transfer protocol, a data size of the determined contents, and the number of the determined contents, and outputs the determined print target information to the content processing unit 130 or the first data interface unit 140.

The print target information may be formatted as one of a list for transmitting a list of contents, as a thumbnail image for transmitting thumbnail images of contents, and as a full image for transmitting full images. As illustrated in Table 1, although print target information may be determined using the data size of contents and the transmission rate of a transfer protocol as the transmission conditions, print target information may also be determined using the number of contents files as the transmission conditions.

When the determined print target information is formatted as the list or the thumbnail images, if the contents to be transmitted do not have a list or thumbnail images corresponding to the determined print target information, the print target information determiner 120 outputs the determined print target information to the content processing unit 130. If the contents to be transmitted have a list or thumbnail images corresponding to the determined print target information, or if the determined print target information is the full image format, the print target information determiner 120 outputs the determined print target information to the first data interface unit 140.

The content processing unit 130 creates a list of the contents to be transmitted or thumbnail images by reducing full images of the contents to be transmitted according to the determined print target information and outputs the thumbnail images of the reduced full images of the contents to the first data interface unit 140.

The first data interface unit 140 transmits contents to the image forming device 200 according to the determined print target information. If the list format has been determined for use with the print target information, the first data interface unit 140 transmits a list of contents determined for transmission to the image forming device 200, if the thumbnail image format has been determined for use with the print target information, the first data interface unit 140 transmits thumbnail images of contents determined for transmission to the image forming device 200, and if the full image format has been determined for use with the print target information, the first data interface unit 140 transmits full images of contents determined for transmission to the image forming device 200.

The image forming device 200 prints contents determined among the contents transmitted from the device 100. To do this, the image forming device 200 includes a second data interface unit 210, a second user interface unit 220, a controller 230, a content editing unit 240, and a printing unit 250. The second data interface unit 210 exchanges data with the device 100. That is, the second data interface unit 210 receives the contents transmitted from the device 100 and transmits a content request signal, which is input from the controller 230, to the device 100.

The second user interface unit 220 displays the contents received from the second data interface unit 210 to correspond to the print target information determined by the device 100. That is, the second user interface unit 220 displays full images of the contents transmitted in the full image format, thumbnail images of the contents transmitted in the thumbnail image format, or a list of the contents transmitted in the list format. In addition, the second user interface unit 220 displays whether the transmitted contents can be printed. Icons replacing contents which cannot be printed are displayed.

The second user interface unit 220 determines contents to be printed among the displayed contents and outputs the determination result to the controller 230.

The controller 230 controls the second data interface unit 210 to send a request for the determined contents to the device 100 and to receive the requested contents from the device 100 in response.

The controller 230 controls the second data interface unit 210 to send a request for full images corresponding to the thumbnail images determined by the second user interface unit 220 to the device 100 and to receive the requested full images from the device 100. Alternately, the controller 230 controls the second data interface unit 210 to send a request for thumbnail images or full images corresponding to the list determined by the second user interface unit 220 to the device 100 and to receive the requested thumbnail images or full images from the device 100.

The controller 230 outputs the received full images to the content editing unit 240 or to the printing unit 250. The content editing unit 240 edits full images to be printed using an editing application and outputs the editing result to the printing unit 250. The printing unit 250 prints the contents received from the controller 230 or the content editing unit 240.

As is described above, in a method and system for printing full images using a device according to the present invention, by transmitting a file list, thumbnail images, or full images according to a data size of contents or a transfer protocol state, before images stored in the device are transmitted to a printer, a transmission rate may be higher and the amount of memory space used in the printer may be reduced.

Although a few embodiments of the present invention have been shown and described, it would 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 invention, the scope of which is defined in the claims and their equivalents.
