The data configuration shown in FIG. 2 sets the packet length 20, the index 21, the reference count 22, the telephone number 23 and the compressed video data 24 to one frame.

The present invention constructed in the above-described form is described in detail below with reference to FIGS. 1, 2 and 3.

First, the memory operation will be described. The memory operation compresses the image information input from the video camera 1 through the image encoder 4 according to the adjustment of the system control unit 11 to form the packet length 20 as shown in FIG. The memory 10 stores the memory. Then, the erasing operation deletes the packet length 20 corresponding to the image information displayed on the monitor 2 from the image data memory 10 during the searching operation described later. Next, the search operation examines the index area 21 of the packets in the image data memory 10 to determine whether the user corresponds to the range selected by the search range button commonly used with the numeric buttons 0 to 9, and then only the corresponding packet is checked. After the collection, the reference count area 22 is reviewed in each packet, the data is restored to the monitor 2 from the referenced packet to the compressed image information area 24, and the reference count 22 is output once. Increase.

Next, if the telephone number area 23 of the packet contains the telephone number information, the user is notified of the number, and when the dialing start command is received through the start button shown in FIG. 3, a DTMF signal is generated to generate a telephone call. Hang.

In this case, if there is no information in the telephone number area 23, the video data is stored but the call has not been made. Therefore, the user is required to select the telephone number directly.

Thereafter, the system control unit 11 records the input telephone number in the telephone number area 23 of the packet so that the user can dial only by using the start button. In addition, the up (↑) and down (↓) buttons shown in FIG. 3 are buttons used to continuously search the video data, and the up button selects the order in which the number of search times decreases and the video data is displayed on the monitor (2). The down button is a button for reversing the video data searched so far.

The process of storing, erasing or searching the above-described video data will be described in more detail as follows.

First, in the process of storing (or storing), first, the user presses the memory button shown in FIG. 3 to cause the video telephone to operate in the storage mode. Next, a name stored in the index area 21 shown in FIG. 2 is input using the button shown in FIG. If this step is omitted, the index area 1 is left blank. Next, the reference count 22 in FIG. 2 is set to zero.

Next, the telephone number stored in the telephone number area 23 of FIG. After capturing the video information to be stored with the video camera 1, the storage button is pressed again. At this time, the system control unit 11 reads the video signal captured by the video camera 1 through the multiplexer and demultiplexer 8 and compresses the video information compressed by the video encoder 4, and reads the packet as shown in FIG. After formation, the data amount (ie, bytes) of the entire packet is calculated. Thereafter, it is placed in the packet length area 20, and is subsequently stored in the last video data stored in the video data memory 10. FIG. In this case, in the preferred embodiment of the present invention, one frame is 30 bytes in order to combine the size of the packet length area 20 with 2 bytes, the index 1 is 10 characters in Korean, and the reference count area 22 is 2 bytes, The telephone number area 23 is set to 15 bytes for storing 15 characters, and the compressed video information area 24 is set between 1K bytes and 3K bytes.

Second, in the search process, first, the user presses the search button shown in FIG. 3 to operate the image data search mode. Press the button corresponding to the initial name (or name) of the neutral, i.e. a for Kim, or o for Lee. And for a, press the button of 1 once, in the case of o press the button of 3 twice. As described above, the search range can be selected by selecting a button, or it can be omitted and executed by referring to the whole. When searching for both the range and the range, the system control unit 11 searches for the reference number area 22 having the highest number. When the above-mentioned up and down buttons are selected and execution of the search is required, the system controller 11 reads the length of the packet from the image data, and multiplexes and demultiplexes the index 21 of each packet through the demultiplexer 8. The decoder 5 restores the image and outputs the image to the monitor 2. Then, when the desired image information is output, the user presses the start button shown in FIG. Then, the system control unit 11 connects to the corresponding counterpart phone by using the telephone number of the telephone number area 23 of the video information packet currently being output.

Lastly, in the process of erasing, when the image data installed in the same procedure as the above-described search process is output to the monitor 2, when the erase button shown in FIG. 3 is pressed, a packet corresponding to the image data is stored in the image. It is erased by the system control unit 11 in the data memory 10. Thereafter, the system control unit 11 rearranges the image data by moving an address to the image data memory 10 of the subsequent packets by the packet length of the erased packet.

In the above-described embodiment of the present invention, the video data memory 10 is limited to the case where the video data memory 10 is fixed in the telephone. However, the PCMCIA / JEIDA standard interface can be used to carry the video data with the memory card. It may be.

As described above, according to the present invention, since the telephone number is searched using the image data, it has a visual effect and is convenient to use. In addition, business cards, photographs, or pictures that can represent the phone number of the other party are adopted as video data, so that the phone can be stored in the memory with the automatic dialing. In addition, in order to increase the efficiency of the search, the scope of the search is designated for each video data, and since the search is performed from the video data with a high frequency of search, there is a big advantage that a high speed search is possible.
