3 is a flowchart illustrating an appointment time alarm processing procedure executed by a time alarm / background screen control device of a portable communication terminal according to the present invention.

First, the controller 40 of the portable communication terminal waits for setting of a call mode or a time alarm mode (that is, appointment time guide mode or schedule management mode) based on a program registered in the program storage 42. (Step 60).

When the time alarm mode item is selected from the menu displayed on the LCD panel 24 by operating the menu button 16 of the keypad 10 in the standby mode (YES in step 62), the controller 40 ) Sets the corresponding portable communication terminal to the time alarm mode.

In the time alarm mode, a voice input of alarm contents is enabled through the voice input unit 30, and the input voice is applied to the controller 40 through the voice / image compression processor 52. The control section 40 stores the compressed voice in the data memory 48 under flag setting (step 64).

Then, the controller 40 receives the setting of the alarm time set from the 10-key of the keypad 10 and stores it correspondingly in the data memory 48 (step 66).

Here, the registration order of the alarm contents input in step 64 and the alarm time in step 66 may be mutually changed.

In the state in which the data under the time alarm mode is registered by the above-described process, the control unit 40 controls the alarm time stored in the data memory 48 based on, for example, its own soft timer or time data by the time display unit 44. To determine if it is reached.

If it is determined that the alarm time has been reached (YES in step 68), the controller 40 preferentially notifies the arrival of the alarm time by the sound and / or vibration set for the call alert of the portable communication terminal. The alarm contents stored in the data memory 48 are read and applied to the voice / image restoration processing unit 54, and the alarm contents reproduced by the voice / image restoration processing unit 54 are stored in the voice output unit (2). 32), listening is possible.

According to the present invention, when the power is turned off while the time alarm mode is set for the corresponding portable communication terminal, it is impossible to notify the time alarm, and the controller 40 is set even if the power is turned off. It is preferable to add a battery of a corresponding portable communication terminal or an appropriate backup power source so that the minimum power is applied to achieve the time alarm function.

4A and 4B are flowcharts for explaining an example of a background screen registration process and an image call process applied to a video call executed by a time alarm / background screen control apparatus of a portable communication terminal according to the present invention.

First, the background registration mode will be described with reference to FIG. 4A. The background registration mode is set among various menus by the menu button 16 and the four-way button 22 on the keypad 10 (step 80).

When the background screen registration mode is set, the control unit 40 executes a background screen registration procedure (step 82). The registration of the background screen is an image captured by the imaging unit 26 (for example, the surrounding environment). Transfer images during a video call with an image or an image downloaded online from a website, for example, an image scanned from a scanner, or with a call partner under operation of the data communication button 18 under operation of the data communication button 18. The received specific image is selectively utilized to be changed, and the registered background image is stored in the image memory 46.

When the registration procedure of the background screen is completed (YES in step 84), the control unit 40 returns to the mode setting (especially the call waiting mode) standby state.

Therefore, when a call is generated from the corresponding portable communication terminal or a call signal arrives to the portable communication terminal and is applied through the call signal processing unit 50, the control unit 40 first sets the call mode (step 90). ).

In the state where the call mode is set, the controller 40 checks the background mode set in the corresponding portable communication terminal (step 92), and when the background mode is the caller image mode (YES in step 94). The control unit 40 proceeds to step 96 to execute control for transmitting an image captured by the imaging unit 26 during a call.

That is, when the background screen setting mode of the corresponding portable communication terminal is the caller image mode, the voice inputted from the voice input unit 30 and the image picked up by the image pickup unit 26 are transferred by the voice / image compression processor 52. It is compressed by a predetermined algorithm (MPEG) and transmitted through the antenna 58.

Then, the voice and / or image transmitted from the call partner are restored by the voice / image restoration processing unit 54 so that the voice is reproduced through the voice output unit 32 while the image is displayed on the LCD panel 24. Will be displayed.

On the other hand, if the caller image mode is not set as a result of the determination in step 94, the controller 40 proceeds to step 98 to determine whether it is a background mode registered in the image memory, and the background mode Is determined (YES in step 98), the controller 40 reads out a specific image set from various background images stored in the image memory 46 and provides the image to the image compression processor 52 through the audio input unit 30. The voice is input and compressed to be delivered.

If the registered background picture mode is not set as a result of the determination in step 98, the process proceeds to step 102 where the video call mode is turned off (i.e., only the voice call mode is operated by the operation of the video call mode setting button 20). If the video call mode is turned off, the process proceeds to step 104 where only the voice input from the voice input unit 30 is executed by the voice / image compression processing unit 52. It is compressed to be delivered to the other party.

5 is a flowchart for explaining another example of a video call process executed by the time alarm / background screen control device of the portable communication terminal according to the present invention.

That is, when the call mode is set (step 120), the control unit 40 first applies an image selected from various images stored in the image memory 46 to the voice / image compression processing unit 52, and the voice input unit. It is compressed by the voice input at 30 and a predetermined compression algorithm to be transmitted to the call partner.

If the identity of the call partner (i.e., the caller) is verified during the transmission of such a background image and the transfer is necessary in the video call mode, and the video call mode setting button 20 is operated (i.e., YES in step 124). The controller 40 activates and controls the imaging unit 26 so that the image captured by the imaging unit 26 is compressed by the audio / image compression processing unit 52 and transmitted to the call partner. (Step 126).

In the state where such a video call is executed, the controller 40 determines whether the call is terminated, and when the call is terminated, the controller 40 proceeds to step 130 and executes control to return to the registered background screen mode.

6 is a flowchart for explaining another example of a video call process executed by the time alarm / background screen control apparatus of the portable communication terminal according to the present invention.

First, when the call mode is set in step 150, the controller 40 proceeds to step 152 to determine whether the call is made from the portable communication terminal.

As a result of the determination, when the transmission is made from the corresponding portable communication terminal (i.e., YES in step 152), the control section 40 proceeds to step 154, whereby the video call mode is set by the operation of the video call mode setting button 20. It is determined whether it is set.

If the image call mode is set as a result of the determination, the flow advances to step 156 to activate the imaging section 26 so that the image captured by the imaging section 26 is applied to the audio / image compression processing section 52 to The voice from the voice input unit 30 is compressed and then transmitted to the call partner.

On the other hand, if the video call mode is not set in step 154, the process proceeds to step 158, in which a picture selected from a plurality of pictures registered in the image memory 46 reads out a background picture, and the audio / image compression processing section 52 to be delivered to the other party.

When the call arrives at the corresponding portable communication terminal as a result of the determination in step 152, the process proceeds to step 160 where the telephone number of the call counterpart (that is, the calling party) that caused the call is recognized ( That is, in step 160, the controller 40 controls the image picked up by the imaging unit 26 according to the operation of the video call mode setting button 20 through the audio / image compression processing unit 52. It is sent to the other party.

On the other hand, if the telephone number of the calling party is not recognized in the step 160, the control section 40 shifts the control to step 164 to read a specific picture selected from the pictures stored in the image memory 46 and the voice. / To the image compression processing unit 52, so that the call is made by setting the registered image as a background image in the state that the call partner is not recognized.

On the other hand, the present invention is not limited to the above examples and various changes and modifications can be made within the scope not departing from the technical gist and gist of the invention.

For example, in the time alarm mode, when the set time is reached, the alarm may be transmitted during a call. In the mode in which the current time is informed, the current time data is enlarged and displayed on the LCD panel to ensure better identification. Also preferred.

As described above, according to the time alarm / background screen control apparatus of the portable communication terminal according to the present invention, as the current time is informed by the portable communication terminal by voice, the need to check the LCD panel of the portable communication terminal is eliminated. For example, if a user registers a specific time and registers, the alarm is generated in the state that the time is reached, and the previously registered alarm contents can be listened to, thereby enabling schedule management.

Also, in the case of a video call, a selective video call can be made by selectively transmitting a background image according to a call partner or by controlling an image captured directly by the imaging unit to be transmitted.
