A speaker 25 is provided next to the camera 22 at the top of the terminal main body 20a, and functions as a sound output unit. A microphone 26 is provided at the bottom of the terminal main body 20a. Sound is input to the microphone 26, and the sound of the other party's voice, sound notifying an in-corning call, alarms, and the like, are output from the speaker 25. An extendable antenna 27 is provided on top of the terminal main body 20a. A built-in RF section 48 (explained later) transmits and receives image data and sound data via the antenna 27.
An outside power connecting section 28 is provided on the other side of the terminal main body 20a, and connects via an adaptor to an AC power source such as a wall socket. An outside sound output section 29 is similarly provided on the other side of the terminal main body 20a, and is connected to an ear-phone or the like.
A battery lid 24 is provided in the rear side of the terminal main body 20a, and can be removed and attached to a storing section in which a battery is accommodated. A stand 24a is joined to the battery lid 24 and can be turned withiri a predetermined angle. By turning the stand 24a so as to increase the angle, the mobile communication terminal 20 can be supported in a sloping position on an installation surface.
Subsequently, the functions of the mobile communication terminal 20 having the visual telephone function described above will be explained based on the block diagram of Fig. 4.
As shown in Fig. 4, a simple-format information termina120 comprises an image sensor 36 included in the camera 22 which converts an image formation object into an electrical signal (pixel signal), an A/D converter 37 which converts the output of the image sensor 36 to digital signals, a processor 38 comprising a dither image processing section 39 which converts the output from the A/D converter 37 to dither image data and a sound processing section 40, a CPU 43 which forms a control unit for controlling the telephone function using a communication unit such as a PHS and data conununication functions, an application registering section 44 which forms a registering unit for storing a first application program for executing the telephone function, a second application program for executing the data communication function, and a thir<i application program for executing a visual telephone function, a memory 45 which stores call information data, such as text transmitted and received by data communicat:ion, and image data, a display driver 46 which drives a display section comprising the monitor 21 for displaying images and the like, a key input interface 47 which connects control section comprising the control key 23 for telephone and data communication, capturing, reproducing and transferring images, to the CPU 43, and an RF section 48 which the antenna 27 is connected to for telephone and data communication with ithe terminal of another party by using a PHS line.
The CPU 43 includes an information identifying section 43a comprising an data type identifying unit which identifies types of data based on the data type information appended as headers to the received data.
Subsequently, the operations and controls of the niobile communication terminal which a telephone function is appended to, as described in the above constitution, will be explained based on the flowchart shown in Fig. 5.
The mobile communication terminal 20 receives data via the antenna 27 and the RF section 48 (step (hereinafter termed "S") 301).
When the CPU 43 determines that the received information is a call-up to itself, the CPU 43 carries out call-up and uses its information identifying section 43a to identify the type of data which is appended as a header to the received data (S302).
The CPU 43 controls the display driver 46 so as to display the type of the in-coming telephone communication, data communication or visual telephone communication on the display section comprising the monitor 21 (S303).
Since the user can learn the type of in-coming communication from the display, he can handle the communication appropriately when he ansvvers.
The user answers by pressing a communication key among the control key 23 (S3024, S308, or S309). In the case of sound data, the CPU 43 activates an application for telephone communication from the application registering section 44 (S305). In the case of text data, the CPU 43 activates an application for data communication (S307).
Consequently, telephone conversation and data reception can be smoothly controlled.
In the case of image and sound data, the CPU 43 activates an application for visual telephone from the application registering section 44 (S309).
After an application appropriate to the information type has been activated in this way, the user can control the communication smoothly.
According to the visual telephone system using the mobile communication terminal 20, when a call is received, the CPU 43 activates an application which is suitable to the type of data based on the data type information appended as a header to the received data. Therefore, it is not necessary to activate functions of' a mode or the like in correspondence with the information type. Consequently, the visual telephone system for visual communication can be smoothly controlled, and the amount of control executed by the user can be greatly reduced.
The above embodiment described an example in which the display can be viewed on the monitor 21 of the mobile communication terminal 20, but the type display can be identified audibly. For example, the audio features and patterns of the sound notifying that there is an in-coming call can be set to correspond separately to data communication and visual telephone.
In the embodiment described above, the mobile coarnmunication terminal 20 which a visual telephone function is appended to comprises a moinitor 21 and a camera 22, provided together in a single body. Alternatively, a unit for appending the visual telephone function may be separately provided to the mobile communication terminal.
One example of this type of mobile communication terminal will be explained.
Figs. 6A and 6B are diagrams showing the outside of a mobile communication terminal 20. Fig. 6A is an external perspective view of a detachable imaging unit, and Fig.
6B is an external perspective view of a visual telephone system in which the detachable imaging unit has been provided in a single body with the miobile communication terminal.
As shown in Figs. 6A and 6B, the detachable imaging unit 52 is attached to the mobile communication termina151, and comprises a camera unit 54 for capturing an image of the object. The camera unit 54 is provided above a PC card slot 56, and can be rotated around a supporting section 55 so as to change its capturing direction in the direction of the arrow. An electronic circuit is provided in the PC card slot 56 portion, and a battery storage section 53 is provided therebelow.
The mobile communication terminal 51 has a data communication function and a telephone function using a communication unit, such as a P'HS, and as above comprises a top flip comprising a monitor 57 as a display section, a speaker 63, an antenna 60, and the like; and a bottom flip comprising a control section which comprises control key including having ten-key, selection key, and function keys such as a communication key 58 and an attachment decision key 59 for determining whether the user has decided to attach. The top and bottom flips can be folded together.
The visual telephone system is realized by attaching the PC card slot 56 of the detachable imaging unit 52 to a slot connection terminal, provided at the lower end of the bottom flip of the mobile communication terminal 51.
As shown in Fig. 7, in the visual telephone system =which comprises the detachable imaging unit 52 attached to the mobile communication terrninal 51 in the manner described above, the PC card slot 56 is provided on the detachable imaging unit 52 side and a slot connection terminal 64 is provided on the mobile communication terminal 51 side.
By attaching the PC card slot 56 of the detachable imaging unit 52 to the bottom flip of the mobile communication terminal 51, the PC card slot 56 of the detachable imaging unit 52 becomes connected to the slot connection terminal 64 of the mobile communication terminal 51, enabling signals to be exchanged between the processor 38 of the detachable imaging unit 52 and the CPU 43 of the mobile communication terminal 51.
The CPU 43 of the mobile communication terminal 51 further comprises an attachment status detector, comprising an attachment status detecting section 43b, which detects whether or not the detachable imaging unit 52 is attached.
As shown in Fig. 8, in this type of visual telephone system, when the data type information comprises image and sound data, the processes executed from S308 onwards are different from those in the case of the single-body mobile communication terminal 20 described earlier.
When the data type information comprises image and sound data, the CPU 43 uses the attachment status detecting section 43b to determine wllether the detachable imaging unit 52 is attached (S310).
When it is determined that the detachable imaging unit 52 is attached from the start, an application for visual telephone is activated from the application registering section 44 (S311).
On the other hand, when the detachable imaging unit 52 is not attached, a message suggesting attachment is visually or audibly informed and iit is determined whether the user has decided to attach (S312).
When the user decides not to attach and manipulates the attachment decision key accordingly, the line is disconnected (S313). When the use;r has decided to attach, the CPU 43 grants a delay and waits for a predetermined period of time. In addition, the CPU
43 transmits information, stating that the detachable imagii:ig unit 52 is being attached, to the terminal of the other party.
The attachment status detecting section 43b once again determines whether the detachable imaging unit 52 has been attached (S3 10). The line is disconnected when the predetermined delay time has elapsed.
In the case where the user has not manipulated the attachment decision key 59 at all, the line is disconnected after the predetermined period of time has elapsed.
When the detachable imaging unit 52 has been attached, the application for visual telephone is activated from the application registering section 44 in the same way as when the detachable imaging unit 52 was attached from the start (S311).
According to the visual telephone system using the mobile communication termina151, when a call is received after the visual telephcrne function has been appended by attaching the detachable imaging unit 52, the CPU 43 activates an application which corresponds to data type information, appended as the header of the received data.
Therefore, there is no need for controls such as activating a mode in accordance with the type. Consequently, controls in the visual telephone systern using visual communication can be executed smoothly, and the amount of control which must be executed by the user can be greatly reduced.
The visual telephone function can be appended to the mobile communication terminal 51 extremely easily by attaching the detachable inaaging unit 52 to the mobile communication termina151. This detachable imaging unit therefore has excellent general versatility, and can be used easily in various types of mobile communication terminal.

Subsequently, the operations and controls of the niobile communication terminal which a telephone function is appended to, as described in the above constitution, will be explained based on the flowchart shown in Fig. 5.
The mobile communication terminal 20 receives data via the antenna 27 and the RF section 48 (step (hereinafter termed "S") 301).
When the CPU 43 determines that the received information is a call-up to itself, the CPU 43 carries out call-up and uses its information identifying section 43a to identify the type of data which is appended as a header to the received data (S302).
The CPU 43 controls the display driver 46 so as to display the type of the in-coming telephone communication, data communication or visual telephone communication on the display section comprising the monitor 21 (S303).
Since the user can learn the type of in-coming communication from the display, he can handle the communication appropriately when he ansvvers.
The user answers by pressing a communication key among the control key 23 (S3024, S308, or S309). In the case of sound data, the CPU 43 activates an application for telephone communication from the application registering section 44 (S305). In the case of text data, the CPU 43 activates an application for data communication (S307).
Consequently, telephone conversation and data reception can be smoothly controlled.
In the case of image and sound data, the CPU 43 activates an application for visual telephone from the application registering section 44 (S309).
After an application appropriate to the information type has been activated in this way, the user can control the communication smoothly.
According to the visual telephone system using the mobile communication terminal 20, when a call is received, the CPU 43 activates an application which is suitable to the type of data based on the data type information appended as a header to the received data. Therefore, it is not necessary to activate functions of' a mode or the like in correspondence with the information type. Consequently, the visual telephone system for visual communication can be smoothly controlled, and the amount of control executed by the user can be greatly reduced.
The above embodiment described an example in which the display can be viewed on the monitor 21 of the mobile communication terminal 20, but the type display can be identified audibly. For example, the audio features and patterns of the sound notifying that there is an in-coming call can be set to correspond separately to data communication and visual telephone.
In the embodiment described above, the mobile coarnmunication terminal 20 which a visual telephone function is appended to comprises a moinitor 21 and a camera 22, provided together in a single body. Alternatively, a unit for appending the visual telephone function may be separately provided to the mobile communication terminal.
One example of this type of mobile communication terminal will be explained.
Figs. 6A and 6B are diagrams showing the outside of a mobile communication terminal 20. Fig. 6A is an external perspective view of a detachable imaging unit, and Fig.
6B is an external perspective view of a visual telephone system in which the detachable imaging unit has been provided in a single body with the miobile communication terminal.
As shown in Figs. 6A and 6B, the detachable imaging unit 52 is attached to the mobile communication termina151, and comprises a camera unit 54 for capturing an image of the object. The camera unit 54 is provided above a PC card slot 56, and can be rotated around a supporting section 55 so as to change its capturing direction in the direction of the arrow. An electronic circuit is provided in the PC card slot 56 portion, and a battery storage section 53 is provided therebelow.
The mobile communication terminal 51 has a data communication function and a telephone function using a communication unit, such as a P'HS, and as above comprises a top flip comprising a monitor 57 as a display section, a speaker 63, an antenna 60, and the like; and a bottom flip comprising a control section which comprises control key including having ten-key, selection key, and function keys such as a communication key 58 and an attachment decision key 59 for determining whether the user has decided to attach. The top and bottom flips can be folded together.
The visual telephone system is realized by attaching the PC card slot 56 of the detachable imaging unit 52 to a slot connection terminal, provided at the lower end of the bottom flip of the mobile communication terminal 51.
As shown in Fig. 7, in the visual telephone system =which comprises the detachable imaging unit 52 attached to the mobile communication terrninal 51 in the manner described above, the PC card slot 56 is provided on the detachable imaging unit 52 side and a slot connection terminal 64 is provided on the mobile communication terminal 51 side.
By attaching the PC card slot 56 of the detachable imaging unit 52 to the bottom flip of the mobile communication terminal 51, the PC card slot 56 of the detachable imaging unit 52 becomes connected to the slot connection terminal 64 of the mobile communication terminal 51, enabling signals to be exchanged between the processor 38 of the detachable imaging unit 52 and the CPU 43 of the mobile communication terminal 51.
The CPU 43 of the mobile communication terminal 51 further comprises an attachment status detector, comprising an attachment status detecting section 43b, which detects whether or not the detachable imaging unit 52 is attached.
As shown in Fig. 8, in this type of visual telephone system, when the data type information comprises image and sound data, the processes executed from S308 onwards are different from those in the case of the single-body mobile communication terminal 20 described earlier.
When the data type information comprises image and sound data, the CPU 43 uses the attachment status detecting section 43b to determine wllether the detachable imaging unit 52 is attached (S310).
When it is determined that the detachable imaging unit 52 is attached from the start, an application for visual telephone is activated from the application registering section 44 (S311).
On the other hand, when the detachable imaging unit 52 is not attached, a message suggesting attachment is visually or audibly informed and iit is determined whether the user has decided to attach (S312).
When the user decides not to attach and manipulates the attachment decision key accordingly, the line is disconnected (S313). When the use;r has decided to attach, the CPU 43 grants a delay and waits for a predetermined period of time. In addition, the CPU
43 transmits information, stating that the detachable imagii:ig unit 52 is being attached, to the terminal of the other party.
The attachment status detecting section 43b once again determines whether the detachable imaging unit 52 has been attached (S3 10). The line is disconnected when the predetermined delay time has elapsed.
In the case where the user has not manipulated the attachment decision key 59 at all, the line is disconnected after the predetermined period of time has elapsed.
When the detachable imaging unit 52 has been attached, the application for visual telephone is activated from the application registering section 44 in the same way as when the detachable imaging unit 52 was attached from the start (S311).
According to the visual telephone system using the mobile communication termina151, when a call is received after the visual telephcrne function has been appended by attaching the detachable imaging unit 52, the CPU 43 activates an application which corresponds to data type information, appended as the header of the received data.
Therefore, there is no need for controls such as activating a mode in accordance with the type. Consequently, controls in the visual telephone systern using visual communication can be executed smoothly, and the amount of control which must be executed by the user can be greatly reduced.
The visual telephone function can be appended to the mobile communication terminal 51 extremely easily by attaching the detachable inaaging unit 52 to the mobile communication termina151. This detachable imaging unit therefore has excellent general versatility, and can be used easily in various types of mobile communication terminal. The detachable imaging unit can be attached extremely easily to communication terminals such as a personal computer comprising a communication unit, thereby appending the visual telephone function thereto.
The above example described a PHS communication unit. However, the communication unit is not limited to PHS, and can be applied to a great variety of communication units such as PDC, CDMA, GSM, WCDMA, and CDMA2000.
As described above, according to the visual telephone system using the mobile communication terminal of the present invention, when a call is received, a controller activates an application which corresponds to data type information, appended as the header of the received data. Therefore, there is no need fo:r controls such as activating a mode in accordance with the type. Consequently, controls in the visual telephone system using visual communication can be executed smoothly, and the amount of control which must be executed by the user can be greatly reduced.
