(2b) shows an on-screen display form when the user wants to check the call rates up to now, and displays the total number of calls and the total call rates.

(2c) shows an on-screen display form when the user wants to check the call history, and displays the area code and the call rate in each call.

3 is a control flowchart for processing and displaying telephone usage information according to the present invention, and FIG. 4 is a flowchart of a telephone usage information processing routine in FIG.

The present invention will be described in detail based on the above configuration.

First, in step (3a), the microcomputer (2) performs an initialization operation and then proceeds to step (3b), and the area code and the counterpart according to the relative area inputted by the user using the remote control (8) and the panel switch (6). The basic call charge according to the designation and the additional charge information according to the timeout are received and stored in the nonvolatile memory 3. The storage form of the information is stored in a table form as shown in Table 1 below.

TABLE 1

In step (3b), after inputting information such as an area code according to the counterpart area, a base call fee according to the counterpart area, and an additional fee based on timeout, in step (3c), the microcomputer (2) is connected to port 3 and port 4; Check to see if the telephone bill reset signal is input from the remote controller (8) and the panel switch (6). When the telephone rate reset signal is inputted as a result of the check, the process proceeds to step 3d to clear the telephone rate details input up to that point in the nonvolatile memory 3 and loops to step 3c. In this case, as the nonvolatile memory 3, an esquare pyrom may be used.

If it is determined in step (3c) that the telephone rate reset signal is not input, the process proceeds to step (3e) and the microcomputer 2 determines whether the total call rate confirmation signal is input from the panel switch 6 and the remote controller 8. If it is checked that the total call rate confirmation signal is input, the process proceeds to step 3f to display the total call rate and loops to step 3c. At this time, the microcomputer 2 reads the total call rate information from the nonvolatile memory 3 and outputs it to the OSD chip 4. Then, the ODS chip 4 generates the corresponding text signal and applies the text signal to the OSD controller 9. The OSD controller 9 mixes the total call rate and the total number of calls on the TV screen 5 by mixing with the video signal. Displayed as shown in Figure 2b.

However, if the total call charge confirmation signal is not in step (3e), the process proceeds to step (3g) to check whether the total call history confirmation signal is input. At this time, when it is confirmed that the total call history confirmation signal is input, the total call history is displayed in step (3h) and looped to step (3c). At this time, the microcomputer 2 reads the total call history information from the nonvolatile memory 3 and outputs the total call history information to the OSD chip 4. Then, the OSD chip 4 generates the corresponding text signal and applies the text signal to the OSD controller 9, and the OSD controller 9 mixes the video signal with the video signal to display the region of each call on the TV screen 5 as shown in FIG. The number and call charge will be displayed.

However, if the total call history confirmation signal is not input in step (3g), the process proceeds to step (3i) to check whether the call is started. At this time, the call start check is confirmed by recognizing whether the other party's telephone 7 receives the call through the port 2 of the microcomputer 2 from the incoming detection circuit built in the user's telephone 200 of FIG. The microcomputer 2 detects a telephone number input from the user telephone 200 through port 1 from the built-in DTMF detection circuit to determine whether it is a local call or a long distance call. At this time, since the frequency is different according to the telephone number input by the user, it is converted into a pulse through the DTMF detection circuit to recognize the number according to the pulse period. For example, if it starts with "0", it is detected as a long distance call and the area is judged by the following number. If it starts with a number other than “0”, it is regarded as a local call.

Therefore, when the microcomputer 2 detects the call initiation state through the port 2 in the step (3i), the call usage routine is executed in the step (3i) to display the in-call rate calculation and the post-call rate save and each state. If it is not in the call start state, go to step (3k) to execute the general program and loop to step (3c). Here, the call usage information processing routine of step (3j) specifically describes the operation procedure of the call charge calculation, the post-call charge saving, and the display operation of each state. In the step (4a), the microcomputer 2 uses the port 2 Recognizes the start of the call and proceeds to step 4b to detect the telephone number input through port 1 and proceeds to step 4c. In step (4c), the microcomputer (2) detects the telephone number input by the user, reads the calling rate information corresponding to the area code already stored in the nonvolatile memory (3), and calls the call rate according to the passage of the call time. Calculate For example, if the user inputs the number 0342-40-1234, the microcomputer (2) recognizes that it is a long-distance call when the first “0” is input, recognizes the next number 342, and determines that it is Seongnam area. If you hang up after the call (usually within 3 minutes), you should read the information in 25, 26 of Table 1 and accumulate it in 5, 6, 7 to calculate the call charge and call history. Then, proceed to step (4d) to output the rate and time information that is changed according to the converted call rate to the OSD chip (4) to display on the TV screen (5) through the OSD controller (9) and to go to step (4e) Proceed. In step (4e), the microcomputer (2) checks whether the call is completed and displays the result of the charge calculation and the time which is converted by repeating the above operation by repeating the above operation in the step (4c) when the call is still in progress. Do it. However, when the call pigment is recognized through the port 2 of the microcomputer 2 in step (4e), the process proceeds to step (4e) and the call rates and area codes are tape type of the nonvolatile memory 3. Save to area 41, 42 and finish the operation.

As described above, by allowing the image processing apparatus to calculate and display various data and charges according to the use of the telephone on the screen, it is convenient to check the telephone charge and other usage information from time to time.

In addition, by displaying the result of the calculation of the fee, which is converted according to the passage of the call time and the passage of the city, users in the call can refer to this to reduce unnecessary calls. There is an advantage.
