DETAILED DESCRIPTION OF THE EMBODIMENTS
These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
Referring to FIG. 1, a network scan apparatus according to an exemplary embodiment of the present invention includes a scanner 20, an output device 30 and at least one host computer 40, which are interconnected through a network 10. The network 10 may be various types of networks and may be based on various types of connections, such as, for example, a LAN, the Internet, a wired network, a wireless network, a combination thereof, etc. The scanner 20 and the output device 30 are connected to the host computer 40 with a client program.
The scanner 20 includes a scanning unit 21 to scan a document, i.e, a manuscript, into an image file to be read, a transmitting unit 23 to transmit the read image file to the host computer 40, and an output selection unit 25 to select whether to output scan file information. The scanning unit 21 scans a document, such as a page of a book, a sheet of paper having text and/or images formed thereon, etc., positioned by a user, and reads a predetermined image file corresponding to the scanned document. Through the network 10, the transmitting unit 23 transmits the read image file to an object host computer 41 selected among the host computers 40. Here, the selection of the object host computer 41 is performed in an operation unit (not shown) provided in the scanner 20. However, the selection of the object host computer 41 may also be performed in operation units which are provided elsewhere, for example, in the object host computer 41. Also, it is understood that various components of the scanner 20 may be combined, such as, for example, the scanning unit 21 and the transmitting unit 23.
The scanner 20 may further include an option selection unit 27 allowing a scan option to be selected. The various types of scan options include, for example, at least one of a color option (color or black and white), a file format, such as .pdf, tiff, etc., and a scan size.
The output selection unit 25 is a scanner option user interface that allows a user to select whether to output information about the scanned image file, i.e., the scan file information generated when the document is scanned by the scanning unit 21. When a user selects the scan file information to be output through the output selection unit 25, the scanner 20 transmits a request to the client program installed in the object host computer 41 requesting scanning results of the document scanning operation.
According to aspects of the present invention, the scan file information includes at least one of a number of pages of a scanned document, a file name of the image file, a size of the image file, a location of the image file, e.g., a folder in which the image file is automatically stored, a resolution of the image file, a linked program to execute the image file, a name of an object host computer, an internet protocol of the network 10 used to transmit the image file from the scanner 20 to the object host computer 41, a thumbnail of the image file, a date and a time of a scanning operation, etc. At least one of these types of scan file information is selected to be output. It is understood that a combination of these types of scan file information may be output as well.
The object host computer 41 collects the scan file information based on image data transmitted from the scanner 20, and decodes and packets the collected scan file information, thereby transmitting the collected scan file information to the output device 30. For instance, when the scan file information is requested by a user, a scan program installed in the object host computer 41, which controls the scanner, creates the scan file information based on the completed scan image data transmitted through the transmitting unit 23. Then, the scan program converts the scan file information to be output through the output device 30, and transmits the scan file information to the output device 30 through the network 10.
The output device 30 outputs the scan file information when a scan file information output is selected through the output selection unit 25. According to an aspect of the present invention, the output device 30 includes at least one of a printer 31 having an output function which prints the scan file information received from the object host computer 41 on a printing medium, such as a sheet of paper, a transparency sheet, etc., and a display 33 having an output function which visually displays the scan file information. When a plurality of output devices 30 are connected to the network 10, a user selects one of the output devices 30 to output the scan file information by using a manipulating unit (not shown) of the scanner 20. It is understood that other output functions besides visual displays and printed media may be employed to output the scan file information according to other aspects of the present invention, for example, audio sounds, etc.
According to an aspect of the present invention, the output device 30 is disposed adjacent to the scanner 20.
