The present invention relates to a memo function processing method in an image processing system, and more particularly, to a memo function processing method capable of recording a phone number or memo contents using an IC card and displaying and confirming the data if necessary.

In general, when a person wanted to leave a note, they could express it as a note. However, the multifunctionalization of image processing systems such as VCRs and TVs is rapidly being promoted, and the development of information and communication systems is not only able to reproduce recorded contents, but also a trend of composite products of image information media is required.

However, in the conventional image processing system, there was no memo function, and when watching a TV, there was a problem in that it was not possible to quickly memo if there was no memo paper or writing utensils around when a call was received.

Accordingly, an object of the present invention is to provide a memo function processing method in which a memo function to be added to an image processing system can be stored on an IC card and displayed on a screen.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

When the memo output key is input in the third step, a sixth step of reading data stored in the active IC card and transmitting a character generation signal to the switching unit is performed.

Based on the above-described configuration, an embodiment of the present invention will be described in detail with reference to FIGS. 1-2.

First, the TV signal processed by the TV image signal processor 70 is transmitted to the display device 80 through the switching unit 60 and displayed by the switching control signal of the microcomputer 60.

At this time, when the memo mode selection key of the key input unit 10 is pressed to store the memo to be memorized, the microcomputer 20 recognizes an input key signal and applies a switching control signal to the switching unit 60. Therefore, the switching unit 60 blocks the TV video signal output from the TV video signal processing unit 70 and sends the R, G, B signals output from the OSD generator 50 to the display device 80.

In addition, the microcomputer 20 receives a memo data signal from the key input unit 10, receives a memo data signal, and reads character data from a ROM inside the microcomputer 20 to activate the first IC card reader ( 30).

The first IC card reader 30 stores text data received from the microcomputer 20, that is, memo contents. In addition, the microcomputer 10 transmits the text data to the OSD generator 50 to generate R, G, and B text data. The R, G, and B character data generated by the OSD generator 50 are applied to the switching unit 60 to display the character selected by the user through the display device 80. In this case, when the memo input is finished, when the memo input completion key of the key input unit 10 is pressed, the microcomputer 20 outputs a switching control signal to the switching unit 60, and the switching unit 60 generates an OSD. The R, G, and B signals output from the unit 50 are cut off, and the TV signals output from the image signal processor 20 are selected and displayed on the display device 80.

On the other hand, when the user wants to check the memo contents recorded, when the memo output key of the key input unit 10 is pressed, the microcomputer 20 outputs a switching control signal again so that the switching unit 60 receives the TV image signal processing unit ( The TV video signal output from 70) is interrupted and the R, G, and B signals output from the OSD generator 50 are selected. At this time, the microcomputer 20 sends the enable signal to the first IC card reader 30 or the second IC card reader 40, and stores the data stored in the active IC card 31 or the standby IC card 41. Is read and output to the OSD generator 50. The microcomputer 10 outputs the memo data to the OSD generator 50. The OSD generator 50 receiving memo data from the microcomputer 10 outputs R, G, and B text signals to the switching unit 60 to display the memo contents on the display device 80. Here, recording and accessing the memo data using the active IC card 31 and the standby IC card 41 may replace a battery built in the active IC card 31 or cause the active IC card 31 to fail. Therefore, the recorded memo data loss standby IC card 41 is driven in an active state so that the memo data can be prevented from being duplicated.

Referring to FIG. 1, the flowchart of FIG. 2 showing the above operation will be described. In step 2a, it is checked whether a memo mode selection key signal of the key input unit 10 has been input. That is, if the memo mode is selected and the memo mode is not selected, in step (2b), the switching control signal is output and applied to the switching unit 60 to display a general TV screen output from the TV image signal processing unit 70. do.

However, if the memo mode is selected in step (2a), if the active IC card 31 is inserted into the first IC card reader 30 in step (2c), and if it is inserted, the step (2d) is performed. Perform step (2e). In the step (2d), if the standby IC card 41 is inserted into the second IC card reader 40 by checking whether the standby IC card 41 has been inserted, the step (2e) is performed, and if not, it returns. In step (2e), if the memo input key signal is input and the memo input key signal is input, step (2f) is performed. If the memo input key signal is not input, step (2m) is performed. In step (2f), memo data is input from the key input unit 10, and step (2g) is performed. In the step (2g), the contents of the memo are read from the ROM (not shown) in the microcomputer 10 by the input memo data and sent to the first IC card reader 30 or the second IC card reader 40. Then, it stores in the active IC card 31 or the standby IC card 41 and performs step (2h). In step (2h), it is checked whether the memo contents input is completed. If the memo contents input is not completed, step (2f) is performed again. In step (2i), if the memo is stored in the active IC card 31 or the standby IC card 41, and if it is stored in the standby IC card 41, step (2W) is performed. If it is stored in the active IC card, step (2j) is performed. In the step (2W), the active IC card 31 is inserted into the first IC card reader 30, and is checked if it is not inserted, and if it is inserted, the step (2X) is performed. In the step (2X), the enable signal is sent to the second IC card reader 40 to read the memo contents stored in the standby IC card 41, and the step (2Y) is performed. In the step (2Y), the read memo is sent to the first IC card reader 30 and stored in the active IC card 31. Also, in the step (2j), if the standby IC card 41 is inserted into the second IC card reader 40, it is checked if it is not inserted, and if it is inserted, the step (2K) is performed. In the step (2K), the enable signal is sent to the first IC card reader 30 to read the memo contents stored in the active IC card 31, and the step (2) is performed. In the step (2), the read memo is sent to the second IC card reader 40 and stored in the standby IC card 41. On the other hand, if the memo input key signal is not input in step (2e), it is checked whether the memo output key signal is input in step (2m), and returns if the memo output key signal is not input, and if the memo output key signal is input (2n) Perform the steps. In step (2n), the microcomputer 20 outputs the switching control signal so that the switching unit 60 outputs the R, G, and B signals output from the OSD generator 50 to the display device 80. In step (20), if the active IC card 31 can be read, and if the active IC card 31 cannot be read, step (2S) is performed and if the active IC card 31 can be read (2P) Follow the steps. In step (2P), the enable signal is sent to the first IC card reader 30 to read the memo contents stored in the active IC card 31, and then step (2g) is performed. The memo data read in step (2g) is also sent to the OSD generator 50 so that the OSD generator 50 outputs the R, G, and B signals, and step (2r) is performed. In the step (2r), the R, G, B signals output from the OSD generator 50 are sent to the switching unit 60 to be displayed on the display device 80. If it is impossible to read the active IC card 31 in step (20), it is checked whether the standby IC card 41 can be read in step (2S). Perform the steps. In step (2t), the enable signal is sent to the first IC card reader 30 to read the memo contents stored in the active IC card 31, and then step (2u) is performed. In step (2u), the read memo data is sent to the OSD generator 50 so that the OSD generator 50 outputs the R, G, and B signals, and the step (2V) is performed. In the step (2V), the R, G, B signals output from the OSD generator 50 are sent to the switching unit 60 to be displayed on the display device 80.

As described above, by recording the phone number or memo contents by using an IC card in the image processing system and displaying and confirming them if necessary, the function improvement and reliability of the image processing system can be improved and the memo contents can be recorded without a writing tool. There is an advantage to that.
