FIG. 4 is a block diagram of an image forming apparatus 400 having a device for managing images, according to an exemplary embodiment of the present invention. The image forming apparatus 400 includes a storage medium managing unit 430, a control unit 440, a user input unit 450, a hard disk 460, a display unit 470, and a print unit 480. The operation of the image forming apparatus 400 of FIG. 4 will be described with reference to FIG. 10 which is a flowchart of a method of managing images, according to an exemplary embodiment of the present invention.
When a USB memory stick 410 and a memory card 420 are connected to the image forming apparatus 400, the storage medium managing unit 430 initializes the USB memory stick 410 and the memory card 420 under the control of the control unit 440, and initializes the file system of the USB memory stick 410 and the memory card 420 using information on the storage media. The initializing operations may be performed concurrently.
The control unit 440 determines the identification names of the hard disk 460, the USB memory stick 410, and the memory card 420, which are included in or connected to the image forming apparatus 400 (step 1000). The identification names may be determined using a manufacturer's name, a product name, or other information on the storage media.
The storage medium managing unit 430 searches the hard disk 460 to read image files stored in the hard disk 460 (step 1010), searches the USB memory stick 410 to read image files stored in the USB memory stick 410 (step 1020), and searches the memory card 420 to read image files stored in the memory card 420 (step 1030). As illustrated in FIG. 10, the steps 1010, 1020, and 1030 may be concurrently performed.
The control unit 440 determines a display order of the image files read from the storage media (step 1040). The display order may be determined according to an image date, a file format, a file name, or Exif information. For example, if ten image files are read from the hard disk 460, the display order of the ten image files may be displayed in the order of the image date. Image attribute information determining the display order may be included in the image files or may be read from each storage medium, along with the image files.
Under the control of the control unit 440, the display unit 470 displays identification names of storage media 410, 420, and 460 (step 1050), links images read from the storage media 410, 420, and 460 with the displayed identification names of each storage medium, and displays the images in the order determined as described above (step 1060). The displayed images may be thumbnail images included in image files read from the storage media. Also, image data read form the storage media may be reduced or enlarged according to the size of an image display area. The size of the image display area varies according to the number of images which are concurrently displayed on the display unit 470. Thus, the control unit 440 may estimate the size of a display area for one image and then enlarge or reduce the thumbnail images or the images read from the storage media according to the estimated size of the display area.
FIG. 5 illustrates a method of displaying images stored in the storage media according to the identification names of the storage media 410, 420, and 460, according to another exemplary embodiment of the present invention. Here, product names of storage media are horizontally displayed as identification names, and images stored in the storage media corresponding to the displayed identification names are vertically displayed.
FIG. 6A illustrates a method of displaying images stored in a storage medium which is selected by the user input unit 450 and included in or connected to the image forming apparatus, according to an exemplary embodiment of the present invention. A user selects an identification name 500 through the user input unit 450 corresponding to the USB memory stick 410 from the identification names of the storage media of FIG. 5. As illustrated in FIG. 6A, when the user selects the identification name 500 corresponding to the USB memory stick 410, images stored in the USB memory stick 410 are displayed. If a plurality of directories are created in the USB memory stick 410, and image files are stored under the plurality of directories, then the display unit 470 may display the plurality of directories, and then display images stored in the corresponding directories.
When the user selects any one of images displayed on the display unit 470 through the user input unit 450, the selected image is displayed on the whole screen of the display unit 470. For example, as illustrated in FIG. 6B, if the user selects an image A-2 510, the image A-2 is displayed on the whole screen of the display unit 470.
The storage medium managing unit 430 reads the selected image file from the storage media and the print unit 480 prints the selected image using the read image file if printing is requested after any one of the displayed images is selected as described above.
When a new storage medium is connected to the image forming apparatus 400, the storage medium managing unit 430 initializes the new storage medium under the control of the control unit 440, and initializes a file system of the storage medium using information on the storage medium. When the initializing operation is completed, the control unit 440 determines an identification name of the new storage medium, and reads stored image files from the new storage medium through the storage medium managing unit 430. The control unit 440 determines a display order of the read image files using the image attribute information. To update a display, the control unit 440 controls the display unit 470 so the identification name of the new storage medium and the images stored in the new storage medium are displayed along with the identification names of the displayed storage media and the images stored in the storage media.
FIG. 7A illustrates a method of updating an image display when a storage medium is connected to an image forming apparatus, according to an exemplary embodiment of the present invention. According to an exemplary implementation, a card reader is additionally connected to the image forming apparatus 400 of FIG. 4. As illustrated in FIG. 7A, the “card reader” that is an identification name of the new storage medium is added in a row for displaying identification names, and the images stored in a card inserted in the card reader are vertically displayed in the column corresponding to the “card reader”. When the display is updated due to the new storage medium, the size of the display area decreases by as much as one image. Thus, the control unit 440 reduces the displayed images to adjust them to the decreased size of the display area and be redisplayed.
When the storage medium connected to the image forming apparatus 400 is disconnected, the storage medium managing unit 430 deletes a file system of the removed storage medium and all stored information on the storage medium, under the control of the control unit 400. To update the display, the control unit 440 controls the display unit 470 so the identification name of the removed storage medium and the corresponding images are removed from the identification names of the displayed storage media.
FIG. 7B illustrates a method of updating an image display when a storage medium is disconnected from an image forming apparatus, according to an exemplary embodiment of the present invention. According to an exemplary implementation, the USB memory stick 410 is disconnected from the image forming apparatus 400 of FIG. 4. As illustrated in FIG. 7B, an identification name of the USB memory stick 410 and images corresponding to the identification name are removed from the display. When the display is updated due to disconnection of the storage medium, the size of the display area increases by as much as one image. Thus, the control unit 440 enlarges the displayed images to adjust them to the increased size of the display area and to be redisplayed.
The identification names of the displayed storage medium and information on the images corresponding to the storage medium may be stored in and managed by a temporary storage medium (not shown) included in the image forming apparatus 400. FIG. 8 illustrates a data structure for managing identification names and image information of a plurality of storage media in the temporary storage medium (not shown). According to an exemplary implementation, the identification names of the storage media are linked using heads, and the information on the images corresponding to the identification names are linked using tails connected to the heads. As illustrated in FIG. 8, the storage media included in or connected to the image forming apparatus 400 has its head at the same location. In each head, information on the images stored in the corresponding storage media is linked using tails. In addition, adjacent tails linked to different heads may be linked with each other. A link between image information stored in the same storage media is indicated by a solid line, and a link between image information stored in the different storage media is indicated by a dotted line.
The image information stored in the different storage medium may be promptly transferred via the link between the image information stored in the different storage media. For example, when information (tail 1-3) 810 on the image A-3 is accessed while information (tail 2-2) 800 on the image B-2 is accessed, the information (tail 1-3) 810 on the image A-3 can be accessed via the tail 1-2 840 through the dotted lined link, without accessing the tail 1-3 810 via a head-2 820 and a head-1 830.
Although the identification names of the storage media are horizontally displayed, and the information on the images stored in the storage media are vertically displayed in the aforementioned description, the identification names of the storage media and the information on the images may be displayed in an opposite way. The user may choose whether the identification names of the storage media will be horizontally or vertically displayed.
In order to manage the images stored in the plurality of storage media included in or connected to the image forming apparatus through one display screen, the plurality of storage media may be concurrently controlled. Namely, the image data of the plurality of storage media may perform read/write operations at the same time.

The user interface unit 1120 receives an input of a specific function or value, and displays a screen for providing information through a display unit such as a liquid crystal display (LCD). The DSP 1130 performs image processing for image data read from a storage medium, and coverts the image data into a desired format of printable image data. The print unit 1140 prints the converted image data.
The USB control unit 1110 controls external storage media which use the USB memory stick connected to the image forming apparatus, so that a USB storage medium is powered and initiated, and data read/write operations are then performed with respect to the USB storage medium.
The first and second memory card control units 1150 and 1160 verify whether a memory card is inserted into the first and second card slots 1170 and 1180. This facilitates the initialization of the memory card and the performance of the data read/write operations with respect to the memory card. The memory card connected to the image forming apparatus through the first and second card slots 1170 and 1180 may be a compact flash (CF) memory card, a smart media (SM) memory card, an extreme digital (XD) memory card, a memory stick (MS), a secure digital (SD) memory card, and a multimedia card (MMC).
The hard disk control unit 1190 controls the hard disk 1195 included in the image forming apparatus, so that the hard disk 1195 is initialized, and data read/write operations are then performed with respect to the hard disk 1195.
As described above, the plurality of storage media included in or connected to the image forming apparatus are respectively controlled by independent control units. The control units controlling the storage media are also operated in response to independent control signals without interference. The plurality of storage media included in or connected to the image forming apparatus may be concurrently controlled due to these independent control units.
Referring to FIG. 11, the USB storage medium connected to the image forming apparatus, a first memory card connected to the first card slot 1170, a second memory card connected to the second card slot 1180, and the hard disk 1195 are respectively controlled by independent control units including the USB control unit 1110, the first memory card control unit 1150, the second memory card control unit 1160, and the hard disk control unit 1190. Control signals for controlling the control units 1110, 1150, 1160, and 1190 are independently generated by the central processing unit 1100.
FIG. 12 is a block diagram of control units for concurrently controlling the plurality of storage media, which are the USB control unit 1110, the first memory card control unit 1150, the second memory card control unit 1160, and the hard disk control unit 1190, according to an exemplary embodiment of the present invention. The control units 1110, 1150, 1160, and 1190 each have a file system, a driver, and a controller. The USB control unit 1110 includes a first file system 1205, a first driver 1210, and a first controller 1215. The first memory card control unit 1150 includes a second file system 1220, a second driver 1225, and a second controller 1230. The second memory card control unit 1160 includes a third file system 1235, a third driver 1240, and a third controller 1245. The hard disk control unit 1190 includes a fourth file system 1250, a fourth driver 1255, and a fourth controller 1260.
The control units 1110, 1150, 1160, and 1190, and the file systems, the drivers, and the controllers included in the control units are independently operated.
When the USB storage medium is connected to the image forming apparatus, the first driver 1210 verifies device information of the connected USB storage medium through the first controller 1215. The first driver 1210 then initializes the USB storage medium. In the initiating process, the driver 1210 analyses attribute information on the USB storage medium, such as capacity, write protect, sector size, manufacturer, and serial number. When read/write operations are facilitated in the USB storage medium, the driver 1210 provides an application programming interface (API) through which the USB storage medium is controlled and which has the attribute information on the storage medium.
An application 1200 initiates the first file system 1205 through the API. In the initiating process, the first file system 1205 stores a file system configuration. For example, the first file system 1205 stores necessary information, such as file location, memory card capacity, and sector size, for controlling the storage media.
When the initializing process is completed for the USB storage medium and the first file system 1205, a desired operation of the application 1200 is performed with respect to the USB storage medium. Specifically, the first driver 1210 generates instruction signals for performing operations requested from the application 1200 according to a control sequence or a protocol of the connected USB storage medium. The first controller 1215 also performs the requested operations, such as power supplying, initializing, and data read/write operations in response to the generated instruction signals.
When a memory card is inserted into the first card slot 1170, the second driver 1225 supplies power to the inserted memory card, and performs the initializing process so that the card can be accessed, as in the case of the aforementioned USB storage medium. The second file system 1220 is initialized by the application 1200. When the initializing process is completed, the desired operation of the application 1200 can be performed with respect to the inserted memory card through the second driver 1225 and the second controller 1230, as in the case of the USB storage medium.
When the memory card is inserted into the second card slot 1180, power is supplied, the memory card and the third file system 1235 are initialized, and then the read/write operations are performed with respect to the memory card.
