In recent years, interest in radio recognition (RFID) technology is increasing as a core technology of ubiquitos and next-generation distribution systems.

RFID is a radio frequency recognition that reads or records information of a tag wirelessly by using a specific frequency band. RFID technology using this method has less information damage than a barcode and does not have to directly access a tag in a reader. This has many advantages, such as being able to read a large number of tags simultaneously at a high speed. For these reasons, RFID technology has been applied to various fields such as electronic identification, electronic money, credit cards, including distribution and logistics.

Such RFID technology is composed of an RFID tag (T), an RFID reader 31 and an antenna (32).

The RFID tag T is a small chip in which information is stored. When an RF signal is received from the RFID reader 31 through the antenna 32, the RFID tag T modulates the phase or amplitude to store the information stored in the tag. Through the RFID reader 31 is returned.

The folder name, the image included in the directory name, and the like.

For example, assume that "Kim Gap-dong", the owner of an electronic ID, enters a branch with an electronic ID. In this case, the personal information of the RFID tag T included in the electronic ID is "Kim Gap-dong". At this time, the sales office is an image of “Kim Gap-dong” recorded as the image taker in the MakerNote area of the image file of the Exif structure among the images stored in the customer management database, which is the storage unit 23, or related images. When there is an image in which "Kim Gap Dong" is recorded as information (for example, Kim Gap Dong's preferred fashion style), the image may be detected and displayed as an image related to the personal information of the received RFID tag T.

In addition, when the images of the storage unit 23 are managed in the album format, when the folder name or directory name of the album is "Kim Gap-dong", the images included under the corresponding folder name or directory name are stored in the received RFID tag T. It may be detected as an image related to human information. In this case, when there are a plurality of images included in the corresponding folder name or directory name, the detected images may be displayed on the display unit 24 in a slide manner.

On the other hand, when the personal information of a plurality of different RFID tags is received in the RFID reader 31, an image related to all the personal information of the received RFID tag is detected (step 304). For example, if the owners of the electronic identification cards "Kim Gap-dong" and "Kim Eul-dong" enter a certain branch at the same time, for example, if they are family members, an image of two people recorded as a photographer or a folder containing two people. You can search for and display images contained in names or directory names.

On the other hand, referring to Figure 4, before the step (304) of detecting the image associated with the human information of the received RFID tag (T), the control unit 25 receives the received RFID tag among the images stored in the storage unit (23) First, a step (303) of checking whether there is an image related to the human information of (T) is performed.

If there is no image associated with the personal information about "Kim Gap-dong" in the above-described step, the default image may be displayed (step 306). On the other hand, the user may set the time for displaying the image on the display unit 24 in advance.

On the other hand, when the RFID reader 31 receives the personal information of the RFID tag different from the previous step (step 301) for a predetermined time (step 307), the image associated with the personal information of the other RFID tag is detected. do.

For example, when the owner of the newly received RFID tag is "Kim Eul-Dong", the controller 23 detects an image related to "Kim Eul-Dong" (step 303) and stops displaying the image for the previous "Kim Gap-Dong", The image for "Kim Eul Dong" is displayed (step 304).

If no personal information is received by the RFID reader 31 for a predetermined time period (for example, "3 minutes"), the control unit 25 automatically turns off the power of the digital image reproducing apparatus ( OFF) to automatically stop the operation of the digital image reproducing apparatus (step 308).

According to the digital image reproducing apparatus having the RFID reader according to the present invention described above, even if the user does not manually designate the display screen, the image associated with the personal information of the RFID tag can be automatically searched and displayed among the stored images. .

In addition, even when the personal information of the RFID tag is changed, the user may automatically search for and display an image associated with the changed personal information without having to manually change the screen.

In addition, the automatic power on / off function may operate the digital image reproducing apparatus only when the personal information of the RFID tag is received for a predetermined time, thereby minimizing power loss.
