Video calling is attracting attention as a killer application that can make effective use of the data transfer speed of the 3G mobile phone service. To promote the appeal of the 3G mobile phone service to users, the video calling function has been pushed forward. There are many products. However, these portable videophone devices require an operation means for selecting whether to use a voice call or a videophone call, which is not necessary in a conventional telephone device using only a voice call.
[0004]
In a videophone device using a fixed communication network, operating means corresponding to each of a voice call and a videophone call are provided, and a user selects and operates an operating means corresponding to a voice call or a videophone call at the start of a call. Thus, there is a method in which a process of selecting whether to make a voice call or a video call and a process of starting a call are performed simultaneously (for example, see Patent Document 1).
[0005]
As another conventional example, the function of each key is changed according to the situation, and the current function of each key is set to a position corresponding to the position of the key on the liquid crystal display screen or a position where it can be intuitively linked. In some cases, a method called a soft key for displaying is used to realize an operation of selecting whether to make a voice call or a video call. Specifically, instead of simply pressing the key used to start a call, the key can be pressed and a direction can be entered. The selection status is displayed on the screen, and a call start process is started by pressing a key. There is also a configuration in which a voice call or a video call is selected depending on the operation state of the camera unit at the time of a call start operation.

FIG. 2 is a flowchart showing a calling procedure (first example) of the mobile videophone device of the first embodiment. Hereinafter, the operation of the first example will be described with reference to this flowchart.
[0030]
In the first example, when a call start key (not shown) which is a part of the external input unit 16 is pressed for a predetermined time (for example, 2 seconds) or more, a videophone call is made. It is assumed that a call is set.
[0031]
During standby (step S200), the control unit 12 of the portable videophone device 1 sets a destination telephone number by the user using the external input unit 16 (step S201), and performs the external input for calling operation. It is determined whether the call start key, which is a part of the unit 16, has been pressed (step S202). When the call start key is pressed, the control unit 12 determines whether or not the key has been pressed for 2 seconds or more by using the time measuring unit 13 (step S203). Here, if the call start key is pressed for 2 seconds or more, a call is made with a video call (step S204), and if not, a call is made with a voice call (step S205).

[0043]
In the first example, when a call start key is pressed for a specified time (for example, 2 seconds) or more when a video call is received, a normal video call for transmitting and receiving a voice and a moving image is performed. It is assumed that video communication is set up so that video communication is received but transmission is performed only by voice (moving image transmission from the camera is off).
[0044]
When a videophone call is received (step S400), the control unit 12 of the portable videophone device 1 determines whether the user has pressed a call start key, which is a part of the external input unit 16, for a call start operation (step S400). Step S401). When the call start key is pressed, the control unit 12 determines whether or not the key has been pressed for 2 seconds or more by using the time measurement unit 13 (step S402). Here, if the button is pressed for 2 seconds or longer, a normal videophone call for transmitting and receiving a voice and a moving image is performed (step S403). Otherwise, the voice and the moving image are received but only the voice is transmitted (from the camera). (The transmission of the moving image is off) is performed (step S404).
[0045]
FIG. 5 is a flowchart showing a receiving operation procedure (second example) of the portable videophone device of the second embodiment.
[0046]
In the second example, when a videophone call is received, when a call start key is pressed a specified number of times (for example, twice) within a specified time (for example, 2 seconds) or more, a normal videophone call for transmitting and receiving a voice and a moving image is performed. If there is no second pressing operation within 2 seconds after the button is pressed, the voice and video will be received, but the voice will only be transmitted (the video transmission from the camera will be off). It is assumed that it has been set.
[0047]
When a videophone call is received (step S500), the control unit 12 of the portable videophone device 1 determines whether the user has pressed a call start key, which is a part of the external input unit 16, for a call start operation (step S500). Step S501). When the call start key is pressed, the control unit 12 determines whether or not the second pressing operation has been performed within two seconds by using the time measuring unit 13 (step S502). Here, if the second press operation is performed within two seconds, a normal video call for transmitting and receiving voice and moving image is performed (step S503). Otherwise, voice and moving image are received but transmission is not performed. A video call with only audio (transmission of a moving image from the camera is off) is performed (step S504).
[0048]
According to the portable videophone device of the second embodiment, there is no need to increase the number of keys and menu operation procedures required for selecting on / off of moving image transmission when a videophone call arrives, and only the conventional voice is used. The mode selection operation at the time of an incoming call can be performed by using the same key as the call start operation of the portable telephone device. For this reason, it is possible to switch between a mode for transmitting and receiving both voice and moving image by a simple and easy-to-understand operation, and a mode for receiving both voice and moving image and transmitting only voice.
[0049]
Note that, similarly to the case where the user sets the wallpaper, the ringtone, and the like from the normal setting menu, the configuration may be such that the specified time and the specified number of times in the above procedure can be set. Similarly, a configuration may be adopted in which it is possible to set whether the pressing time is used or whether a condition combining the number of times of pressing and the like such as pressing twice or more within a specified time is used as the determination condition in the above procedure. Further, instead of not transmitting the moving image from the camera in step S404 and step S504, a still image, a moving image, or the like stored in the memory of the portable videophone device 1 may be transmitted. The still image and the moving image may be set in advance from a setting menu.
[0050]
In a similar manner, the configuration may be such that the determination condition of the video call / video call only for voice can be switched in the setting menu.
[0051]
