Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking as an example a wireless portable terminal having a wireless communication function and an additional function of video reproduction.
Note that the communication (including telephone call) function may be wired, but in this example, a case where wireless communication is performed is illustrated. In addition, reproduction of information including video includes reproduction of only video (whether moving images or still images), reproduction of only audio, or both. However, in the following, moving image reproduction including audio and video is taken as an example.

FIG. 1 shows the configuration of the mobile terminal 1.
The portable terminal 1 includes a transmission / reception unit 101, an application execution unit 102, an audio control unit 103, a video processing unit 104, an earphone detection unit 105, a microphone 106, a speaker 107, an operation unit 108, a memory 109, an incoming call, in a casing 100. It has the alerting | reporting means 110 and the control part 120. Each of these units is connected to one or a plurality of buses 2 in the casing 100, and is controlled by the control unit 120 to execute necessary processing such as processing for a call and processing for video reproduction.

Although not shown in particular, the operation unit 108 is a key for image quality adjustment and function selection hierarchized by menus, a button for video or audio reproduction such as volume and reproduction, and a telephone number input, etc. It has a numeric keypad.
The incoming call notification means 110 is for informing the user that there has been an incoming call, for example, by outputting a ringtone, operating a vibrator or displaying an LED.
The control unit 120 is usually configured by computer-based control means such as a CPU (Central Processing Unit). The control unit 120 controls the functions of the entire mobile terminal 1 by appropriately executing the procedure described in the built-in program in accordance with the operation of the operation unit 108 by the user. The built-in program may be rewritten by a computer connected to the outside.

In the configuration shown in FIG. 1, the microphone 106 and the speaker 107 are for mutually converting the voice of the user or the other party and the call signal (transmission signal or reception signal). This corresponds to a specific example of “internal voice conversion means”. Note that the speaker 107 may be used for audio reproduction in addition to a call, or two large and small speakers may be provided for this purpose.
An earphone microphone 4 as an “external audio conversion unit” and a jack 105A as a “connection unit” to which a microphone or a speaker 5 can be arbitrarily connected are provided on the casing 100 of the portable terminal. The earphone microphone 4 can mutually convert voice and a call signal, and the earphone and the headphone 5 can convert a call signal or another voice signal into voice and output it.
The earphone detection means 105 is connected to the jack 105A, and it is detected by this earphone detection means 105 that the earphone microphone 5 or the like is inserted and connected, and that it is disconnected and disconnected. This detection signal is sent to the control unit 120.

The antenna 3 provided in the housing 100 is connected to the transmission / reception unit 101.
Although the transmission / reception unit 101 is not particularly shown in detail, the transmission / reception unit 101 is roughly divided into a front end unit, a reception side circuit, and a transmission side circuit in terms of circuit blocks. The transceiver 101 also has a reception processing function similar to that of a normal wireless communication device, that is, receives a radio frequency signal transmitted from the base station, sends it to the receiving side, and transmits it to an intermediate (or low) frequency. Various reception processing circuits for performing demodulation and signal processing suitable for the communication method. In addition, the transmission / reception unit 101 performs a function for transmission processing in the same way as a normal wireless communication device, that is, performs signal processing and modulation suitable for a predetermined communication method on a transmission signal such as a call signal, amplifies, and transmits It has various transmission processing circuits for converting it into a frequency signal and transmitting it from the antenna 3 to the base station.

  The application execution unit 102 reproduces and displays information including video. Further, the display unit 102A displays a video image from the application execution unit 102. The application execution unit 102 reproduces and displays video content (and audio) recorded on a built-in or externally inserted recording medium or downloaded via a wireless communication path and stored in the memory 109. Output to region 102A (and speaker 107).

  The sound control unit 103 controls the level (gain) of the sound output to the earphone microphone 4, the microphone 106, and the speaker 107, and the output destination. In this example, the control of the output destination realizes the function of the “switching unit” of the present invention. That is, when the detection result of the earphone detection unit 105 is input to the voice control unit 103 via the control unit 120, the voice control unit 103 indicates that the earphone microphone 4 is connected. Switches the input / output path of the call signal after gain adjustment for the transceiver 101 from the built-in microphone 106 and speaker 107 side to the connected earphone microphone 4 side. Note that the function of this switching unit may be provided to the control unit 120.

  In addition to normal image quality adjustment functions such as screen brightness and contrast, the video processing unit 104 displays an incoming state and a call display to be described later on video output from a playback unit (not shown) in the application execution unit 102. This is a circuit for realizing a function of synthesizing icons to be performed, source information or destination list. When necessary for this processing, the video processing unit 104 can appropriately use the memory 109 as an image memory. The video signal after image quality adjustment or image synthesis is sent to the display means 102 and displayed.

  The control unit 120 of this example is provided with a call processing control unit 121 and a call end control unit 122. These means execute "call processing" and "call end processing", respectively, and the processing procedures are described and implemented in a program in the control unit 120. In the “call processing” and “call end processing”, the control unit 120 controls the corresponding configuration (for example, the voice control unit 103 and the video processing unit 104) in accordance with the program location (subroutine) describing the procedure. Is specifically executed.

  Here, the “call processing” is not only off-hook processing, but also notifies the incoming call notification means 110 shown in FIG. 1 when there is an incoming call for a call, and the source of the incoming call signal. This includes displaying an incoming call display with information and icons on the display means 102A, updating the incoming call history, and the like. Furthermore, when the user tries to make a call, the “call processing” is information of the destination (display of a so-called address book or display of the incoming call history as a destination list), identification of the destination by the selection, and pressing the numeric keypad. Including the display of the assigned number. In these call processes, the information that is necessary when the user is playing back video, for example, combining incoming call display, call display, caller information (phone number) display, etc. with the video being played The processing unit 104 is instructed to display the combined image on the display unit 102A.

  The “call end processing” is a predetermined response, for example, automatically sending a message “cannot answer the phone at present” as a synthesized voice in the memory 110, or This includes actions such as sending and recording a call from the other party in the memory 109, sending an e-mail with a predetermined content such as asking about the other party's requirements, or forcibly terminating the call. In addition, before shifting to these correspondences, a predetermined time is counted in order to give a grace for the user to select a call, and after this time has elapsed, a predetermined correspondence is executed. Although not specifically shown in FIG. 1, a timer is provided in the control unit 120 for this purpose.

Further, in the program of the control means 120, when an incoming call is received during moving image reproduction, it is determined by default that the moving image reproduction mode is maintained. This control is also performed as one of the above “call processing”.
At this time, the user can select in advance whether the sound is to be paused (muted) or set to a very low volume. It is also possible to select stop or pause of the moving image playback mode from this default by user operation after the incoming call or by a change by the user in advance. As a premise at this time, state transition can be arbitrarily performed between the reproduction mode, the stop mode, and the pause mode. Some of these operation items are provided as menu items in the operation unit shown in FIG. 1, and pause and stop are operated by operation buttons.

Next, the operation of the portable terminal 1 having the above configuration will be described.
In the following description, an operation when an incoming call occurs during moving image reproduction will be described, and a detailed description of operations related to normal voice communication and data communication will be omitted.
FIG. 2 is a flowchart for explaining processing when an incoming call occurs during moving image reproduction. Unless otherwise specified, this processing is executed by each unit specified in the above description of the configuration under the control of the control unit 120 shown in FIG. 1, and the step transition is automatic or a request from the user via the operation unit 108. Is done by.
FIG. 3 is a diagram showing the transition of the display screen of the display means 102A shown in FIG. 1 in order to explain the notification method for incoming calls and the like. In the following description, FIG. 1 will be referred to in addition to FIGS.

In steps S1 and S2, a moving image reproduction process is executed.
First, when using a portable recording medium, a user attaches the medium to a slot (not shown) provided in the casing 100 of the portable terminal. In the case of downloading, it is assumed that the desired video content is stored in the memory 109 by performing the procedure. When such a necessary procedure is performed, a list of moving image data is automatically displayed on the display means 102A. When the user selects data including desired video content by key operation (step S1) and presses the play button, moving image reproduction is performed. Start (step S2).
At this time, the moving image is displayed on the display means 102A, for example, a liquid crystal or an organic EL panel as in the state A shown in FIG. In the display screen in this example, a moving image is displayed in the moving image reproduction region 102B, a received electric field strength bar and a clock are displayed in a pictogram (pictogram) display region 102C, and a reproduction state display region located below the moving image reproduction region In 102D, an indicator that moves to display a guide for the remaining time of content, a playback time, and an operation state are displayed.
The reproduced sound at this time is output from the speaker 107 shown in FIG. However, in the case of the headphone 5, it is inserted into the jack 105A and used.

In step S3, the presence / absence of incoming calls is constantly monitored, including during playback of moving images. This is executed by the control unit 120 monitoring the state of the transmission / reception unit 101. If there is an incoming call, the process flow proceeds to step S4, and if there is no incoming call, the process proceeds to the next step S11.
In step S11, the presence / absence of a reproduction end operation is monitored. If there is no operation to end reproduction, the process returns to step S3 again, and steps S3 and S11 are repeated at a predetermined short timing until there is either an incoming call or an operation to end reproduction. When the reproduction is completed, a predetermined reproduction termination process, for example, a process of returning to the moving image data list display is performed, and then the flow shown in FIG. 2 is terminated.

When an incoming call is detected in step S3, the user is notified of the incoming call in step S4 as part of the call process.
In this notification, as shown in the state B of FIG. 3, for example, a display indicating that a call is being received using a part of the playback state display area 102D and the communication source telephone number are displayed. For example, the display screen identifies the transmission source with reference to the received signal and the stored contents of the memory, and sends the telephone number and incoming display information to the video processing unit 104, where it is combined with the video being played back. Is generated. The display of information related to the incoming call may disappear in a certain time, or may be displayed while there is an incoming call. This can be selected by presetting by the user. If the display disappears after a certain period of time, as shown in state C of FIG. 3, a telephone icon or the like may be displayed in the pictograph display area 102C to notify the user that the incoming call continues.
At this time, it is desirable that each display area is adjusted to a position and size where the additional information does not interfere with the moving image. For example, when a moving image is played full screen while leaving the pictograph display area 102C, these additional information can be displayed in the pictograph display area 102C. Alternatively, the moving image reproduction area may be reduced as necessary, and a free area for additional information may be provided.

  It is desirable to notify the user that an incoming call has been received by the incoming call notification means 110 such as a vibrator or LED, at the same time as or after the incoming call notification by display.

In step S <b> 5, the insertion of the earphone microphone 4 is monitored by the earphone detection means 105.
When the earphone microphone 4 is inserted into the jack 105A when the user confirms the other party of the incoming call and makes a call, the plug of the earphone microphone 4 is electrically connected to the bus 2 and the earphone detection 105 indicates that the call can be made. It is confirmed. Then, the detection signal is sent to the control unit 120, whereby the control unit 120 shifts the processing flow to step S6, and executes the call processing necessary for the response in this step.

In the call processing at this time, for example, the moving image area is reduced and displayed to some extent so that the destination information can be selected from the destination list (address book) or the incoming call history. Further, since the display of the transmission destination is temporary, the moving image may be temporarily hidden and the transmission source may be displayed on the full display screen. At this time, the moving image reproduction is continued in order not to impose an extra key operation on the user later.
When the destination is selected by the user or the telephone number is pressed with the numeric keypad, it is displayed on the display means 102A. Thereafter, a call destination is specified, a call signal is transmitted by the transmission / reception unit 101, and when the other party answers, a communication channel for the call is established. After the user operation for establishing the communication path, unnecessary information is not displayed, and the display is mainly based on the moving image playback screen.
As for voice, the voice control unit 103 inputs / outputs the sound of the call to / from the earphone microphone 4, and the communication path on the microphone 106 and speaker 107 side is blocked.

  In the above call processing, information display and erasure are based on image synthesis by the video processing unit 104, as in the case described above.

In step S7 of FIG. 2, it is monitored whether the earphone microphone 4 has been removed. If the earphone microphone 4 is not removed, this determination is repeated in a short cycle.
When the earphone microphone 4 is removed, the processing flow proceeds to the next step S8, where off-hook processing, for example, closing of the communication path, recording of the call time, history update, etc. is performed. Further, as part of the call termination process, the display screen is returned to the initial state as shown by state D in FIG.
Thereafter, the process returns to step S11, and only the moving image reproduction is executed until the end.

  On the other hand, if the determination in step S5 described above is “No”, that is, if the insertion of the earphone microphone 4 is not detected, it is assumed that the user does not intend to make a call on the condition that a certain time has passed in step S9, and the call end process is For example, a message is transmitted by e-mail (step S10), and then the process proceeds to an on-hook process (step S8).

  In this example, the video playback mode is maintained by default. However, when the video playback mode is temporarily stopped by the user's selection, the video playback stop position at that time is recorded and stored in step S6 of the call processing in FIG. In addition, after the on-hook processing in step S8, as a part of the call end processing, the moving image playback stop position can be read from the memory and playback can be resumed therefrom.

  In addition, although it has been described that the moving image reproduction is performed, in the case of a still image, for example, it is conceivable to browse an image captured by a camera built in the mobile terminal. In such a case, it is desirable that normal operations such as image browsing, image registration, folder-to-folder deletion, and image deletion can be performed even during a call so that the user can perform these operations during the call. In this way, depending on the content of the call, there is also an advantage that consultation of image selection to be sent can be made.

According to the present embodiment, a call can be made while watching a moving image (or a still image) by making a call with the earphone microphone 4. If the user does not want to watch the movie, the information necessary for the call is displayed at a minimum, so that the user does not have to watch the movie.
In general, the call time is often short, and in such a case, it is inconvenient because the user is forced to perform a key operation for starting the moving image reproduction if the moving image reproduction is stopped every time an incoming call is received. Only when the call is long, it is preferable that the user can make a pause by user operation because the range of user selection is wide.
The portable terminal according to the present embodiment satisfies such a requirement.

Further, in the present embodiment, since the incoming call response can be made by inserting / removing the earphone microphone 4, there is no malfunction that the moving image reproduction is ended by an erroneous key operation.
In addition, display for notification of incoming calls and information for response such as a destination list can be displayed so as not to overlap the portion being played. Therefore, at this time, the user who is watching the moving image can easily be notified of an incoming call without disturbing the viewing, and the user can easily perform an operation for response processing while watching the moving image.
Furthermore, even when there is no intention to respond to the user, the call termination process is automatically executed, and thus such a user can continue watching the video without any operation.

  As described above, according to the present invention, it is possible to realize a portable terminal that is easy to use for a user and hardly causes a malfunction.

  INDUSTRIAL APPLICABILITY The present invention can be applied to the use of a portable terminal having an external voice conversion means (for example, an earphone microphone) that can be detachably connected and has a call function.

It is a block diagram which shows the structure of the portable terminal in connection with this Embodiment. It is a flowchart for demonstrating the process at the time of the incoming call having arisen at the time of video reproduction. It is a figure which shows transition of the display screen of the display means shown in FIG. 1, in order to demonstrate the method of notifications, such as an incoming call.
