Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to an interactive communication apparatus suitable for home use. 
   2. Description of Related Art 
   With the spread of personal computers, the gap between people who know how to use computers and those who do not is widening. This widening gap might well be due to the fact that most personal computer applications, in an effort to improve performance, are equipped with so many functions, including those that novice users never learn to use, that they invite confusion in their operation. 
   Despite the expansion of opportunities to access the internet afforded by advances in broadband and other technologies, in which communication lines are always connected, since there is no personal computer available designed specifically to be usable by virtually anyone, there are people who have been left behind by advances in technology. 
   For example, attempts to achieve a combined TV phone, answering phone, home security system, shopping center, motion picture distribution and medical consultation center in a single integrated personal computer for home use requires selecting the necessary hardware and software and installing the hardware and the software. 
   Not only does such construction require specialized knowledge, but also, because post-installment operation differs depending on the individual hardware and software components, the resulting configuration lacks integration and is so complicated that the average user cannot hope to operate it. 
   In such a situation, mistakes in operation occur and people never learn to use some needed functions because the operation of such functions is too complicated. 
   Moreover, there is no effective combination of individual functions, and as a result it sometimes happens that it is impossible to acquire needed data smoothly.

   Moreover, as shown in  FIG. 1  and  FIG. 2 , the PC unit is of a removable type, in which the above-described input-output devices can be connected just by insertion, for easy removal from and installation in the interactive communication apparatus  1  for repair or expansion. 
   Using the above-described input-output devices connected to the respective interfaces, the interactive communication apparatus  1  is programmed to carry out the functions of a TV phone, an answering phone, a facsimile machine, e-mail, internet, home shopping, home security, movie distribution service and postal service. 
   A communications device for communicating externally is connected to the typical interfaces with which a PC unit is equipped, such as a USB interface, an RS232 interface, a PCI bus, a PCMCIA bus, etc. 
   In the present embodiment, the communications device MDM 1  is an ADSL modem, connected to the USB interface of the PC unit. It should be noted that the type of communications device MDM 1  can be freely selected according to the type of line used. Thus, for example, if a LAN is used, then the communications device MDM 1  may be a LAN card, and if an ISDN line is used then the communications device MDM 1  may be an ISDN modem. Naturally, the communications device selected is connected to the interface on the PC unit that fits that device. 
   The communications device MDM 1  becomes a means of acquiring external image data as well as externally captured image data, as well as a means of transmitting internal data and internally captured image data. The acquisition of external data and externally captured image data as well as the transmission of internal data and internally captured image data described in the present embodiment involve the communications device MDM 1  operating as a physical interface. 
   Acquisition of external data and externally captured image data includes processing data transmitted from the outside into a usable form at the PC unit. Transmission of internal data and internally captured image data externally to the outside includes processing the data at the PC unit into a form that can be received and processed by the receiver. 
   The speaker SP 1  is connected to the USB interface and outputs audio external data as well as audio generated internally at the PC unit. Audio is output and audio communications can be performed through the speaker SP 1  when carrying out the functions of the TV phone, answering phone, facsimile machine, e-mail, internet, home shopping, home security, movie distribution service and postal service. 
   The microphone MIK 1  is built into a telephone receiver  2  provided on a side part of the interactive communication apparatus  1 , and is connected to a USB interface. Audio from the user of the interactive communication apparatus  1  is input as internal data and audio communications can be performed through the speaker SP 1  when using the TV phone, home shopping, home security, movie distribution and other service functions. 
   The image sensor camera CAM 1  is comprised of a CCD camera, and is disposed at a front corner of the interactive communication apparatus  1 and connected to the USB interface. 
   In addition, a detachable cap  3  covers the camera CAM 1 .

   The image sensor camera CAM 2 , which is disposed at a building entrance and the like, is connected to a USB interface, and, in the home security function, senses the image of a visitor to the entrance and reads the sensed image as internally captured image data. 
   In addition, the sensor SNC 1 , which is also disposed at a building entrance or the like and connected to a USB interface, and the home security function detect a visitor at the entrance. When the sensor SNC 1  detects a visitor, the camera CAM 2  is activated and senses the image of the visitor. 
   Moreover, if the sensor SNC 1  detects an intruder after a security lock has been engaged, the user can also address the intruder through a microphone provided on the sensor SNC 1 , contact a security center or the police, and so forth. 
   The liquid crystal display LCD 1  is disposed front and center on the interactive communication apparatus  1  and connected to a video interface. Then, menu choices, external data and externally captured image data acquired by the communications device MDM 1 , internal data acquired from the input devices, and internally captured image data acquired by the camera CAM 1  and the camera CAM 2  can be displayed on the display screen of the liquid crystal display LCD 1 . 
   The facsimile FAX 1  is disposed on the front top of the interactive communication apparatus  1  and connected to a USB interface. The facsimile FAX 1  performs fax data input and-data output, and can also output liquid crystal display LCD 1  display screen data as well as input image data. 
   The touch panel TP 1  is connected to a RS232 interface. The touch panel TP 1  overlays the liquid crystal display LCD 1  display screen, and enables the user to perform a selection by touching the choices, the selections pertaining to the choices, and the various marks. 
   The mouse MUS 1  is connected to a mouse-dedicated interface. Clicking the mouse selects the choices and the various marks displayed on the display screen. 
   The keyboard KB 1  is connected to a keyboard-dedicated interface. Using the keyboard enables the user to select the choices and the various marks displayed on the display screen and to input text. 
   The DVD drive DVD 1  is connected to an IDE interface and is used to install programs in the PC unit, to input files, and so forth. 
   The IC card reader/writer ICR 1  is connected to a USB interface, and inputs credit card data when home shopping. 
   Next, a description is now given of the interactive communication apparatus  1  operating steps and processing routines. 
     FIG. 4  is a flow chart showing a processing routine  1 . When activated, the interactive communication apparatus  1  performs STEP  1 - 01  in processing routine  1 . 
   In a STEP  1 - 01 , the interactive communication apparatus  1  displays items of functions of TV phone, answering phone, facsimile, e-mail, internet, home shopping, home security, movie distribution service and postal service on the liquid crystal display LCD 1  display screen as shown in  FIG. 14 . The display screen in  FIG. 14  displays the movie distribution service and the postal service as “On-Demand Theater” and as “My Post Office”, respectively. 
   A succeeding STEP  1 - 02  confirms that operation of the interactive communication apparatus  1  is finished. Termination of the operation of the interactive communication apparatus  1  can be selected at any time. 
   If termination of the operation of the interactive communication apparatus  1  is not selected, then the processing routine proceeds from STEP  1 - 03  through STEP  1 - 10  and one of the above-described choices is selected using the touch panel TP 1 , the mouse MUS 1  or the keyboard KB 1 . 
   In a STEP  1 - 03 , when “TV phone” is selected, the processing routine proceeds to STEP  1 - 12  and the TV phone function is enabled by the processing routine  2  shown in  FIG. 5 . 
   In a STEP  1 - 04 , when “answering phone” is selected, the processing routine proceeds to STEP  1 - 13  and the answering phone function is enabled by the processing routine  3  shown in  FIG. 6 . 
   In a STEP  1 - 05 , when “FAX” is selected, the processing routine proceeds to STEP  1 - 14  and the fax function is enabled by the processing routine  4  shown in  FIG. 7 . 
   In a STEP  1 - 06 , when “E-mail” is selected, the processing routine proceeds to STEP  1 - 15  and the e-mail function is enabled by the processing routine  5  shown in  FIG. 8 . 
   In a STEP  1 - 07 , when “Internet” is selected, the processing routine proceeds to STEP  1 - 16  and the internet function is enabled by the processing routine  6  shown in  FIG. 9 . 
   In a STEP  1 - 08 , when “Home Shopping” is selected, the processing routine proceeds to STEP  1 - 17  and the home shopping function is enabled by the processing routine  7  shown in  FIG. 10 . 
   In a STEP  1 - 09 , when “Home Security” is selected, the processing routine proceeds to STEP  1 - 18  and the home security function is enabled by the processing routine  8  shown in  FIG. 11 . 
   In a STEP  1 - 10 , when “On Demand Theater” is selected, the processing routine proceeds to STEP  1 - 19  and the movie distribution service function is enabled by the processing routine  8  shown in  FIG. 12 . 
   In a STEP  1 - 11 , when “My Post Office” is selected, the processing routine proceeds to STEP  1 - 20  and the postal service function is enabled by the processing routine  8  shown in  FIG. 13 . 
     FIG. 5  is a flow chart showing a TV phone function processing routine  2 . 
   When the TV phone is selected from among the list of choices displayed, first, in a STEP  2 - 01  it is confirmed that operation of the TV phone is terminated. When TV phone operation termination is selected, processing returns to STEP  1 - 01  of the processing routine  1 . 
   It should be noted that operation of the TV phone can be terminated both after TV phone communication has ended as well as during communication. 
   When in STEP  2 - 01  termination of the operation of the TV phone is not selected, processing proceeds to a STEP  2 - 02  and a list of previously stored e-mail addresses is displayed on the liquid crystal display LCD 1  as possible selections ( FIG. 15 ), so as to be able to select the other party&#39;s line. 
   The names and telephone numbers of other parties are previously matched and registered in the interactive communication apparatus  1 , and therefore the other party&#39;s line can be selected either from the other party&#39;s name or directly from the other party&#39;s phone number. 
   From the displayed list of recipient addresses, the user selects an arbitrary address using the touch panel TP 1 , the mouse MUS 1  or the keyboard KB 1  and connects the line, and the processing routine proceeds to a STEP  2 - 03 . 
   In STEP  2 - 03 , it is confirmed that selection of the other party&#39;s line is finished. If selection is not finished, processing returns to STEP  2 - 02 . If selection is finished, the processing routine proceeds to a STEP  2 - 04 . 
   In STEP  2 - 04 , it is confirmed whether or not the line has been properly connected. If the line has been connected, then the processing routine proceeds to a STEP  2 - 05 . 
   In STEP  2 - 05 , the interactive communication apparatus  1  displays a screen as shown in  FIG. 18  that enables the user either to select a line connection retry or to cancel the connection and terminate the TV phone. 
   When in a STEP  2 - 06  a connection retry is selected, then processing returns to after STEP  2 - 03  and a line connection retry is attempted. On the other hand, when the user elects to cancel the connection, the processing routine proceeds to STEP  1 - 01  of processing routine  1 , a list of choices is displayed on the display screen and operation of the TV phone is terminated. 
   In a STEP  2 - 07 , it is determined whether or not interactive communication apparatus  1  camera CAM 1  internally captured image data display has been selected. 
   If the cap  3  has been removed from the lens of the camera CAM 1 , the interactive communication apparatus  1  assumes that acquisition of internally captured image data has been selected and the interactive communication apparatus  1  acquires an image of the user taken by the camera CAM 1  as internally captured image data. 
   When internally captured image data display has been selected, or is selected, the processing routine proceeds to a STEP  2 - 08  and the internally captured image data is displayed on the display screen. 
   Then, in a succeeding STEP  2 - 09 , audio input via the microphone MIK 1  and the interactive communication apparatus  1  internally captured image data is transmitted to the other party and the processing routine proceeds to a STEP  2 - 10 . In the event that it is not desired to transmit an image of the user to the other party, the cap  3  may be left covering the lens of the camera CAM 1 . 
   Next, in STEP  2 - 10 , the audio transmitted from the other party is output by the speaker SP 1 . 
   Further, in a STEP  2 - 11 , a selection is made to display or not to display the externally captured image data. 
   When display of externally captured image data is selected, the processing routine proceeds to a STEP  2 - 12  and externally captured image data transmitted from the other party is displayed on the display screen. 
   The presence or absence of a display of internally captured image data and externally captured image data is determined by selection of a sensed image data display selection mark  4  ( FIG. 15  and  FIG. 16 ) using the touch panel TP 1 , the mouse MUS 1  or the keyboard KB 1 , so that the user can switch between display and non-display with each selection of the mark  4 . 
   The interactive communication apparatus  1  makes it possible to terminate the display screen display of internally captured image data and externally captured image data at any time. That is, even if the internally captured image data and externally captured image data display screen display termination is selected while the TV phone is in use, display of the internally captured image data and the externally captured image data is terminated. Then, as is described later, when a function other than TV phone is selected and the user shifts to the TV phone function while using that other function, the interactive communication apparatus  1  automatically returns to a display of the display screen in use immediately prior to shifting to the TV phone function. 
   It should be noted that, when internally captured image data and externally captured image data are displayed on the display screen, the interactive communication apparatus  1  can be returned to the display screen displayed immediately prior to shifting to the TV phone function by selecting not the sensed image data selection mark  4  but the marks of the choices displayed on the same display screen. 
   Returning to the display screen displayed immediately prior to shifting to the TV phone function means that it is possible to use the various functions of the interactive communication apparatus  1  and the TV phone function in parallel. 
     FIG. 16  is a diagram showing the display screen displayed when only display of externally captured image data is selected.  FIG. 17  is a diagram showing the display screen displayed when display of both externally captured image data and internally captured image data is selected. In  FIG. 17 , the small image in the upper right corner of the display screen is the internally captured image data and the large image in the lower left of the display screen is the externally captured image data. Moreover,  FIG. 17  is a diagram showing a case in which, by selecting a mark for a choice displayed on the display screen, the interactive communication apparatus  1  is returned to the display screen displayed immediately before shifting to the TV phone function, and therefore the sensed image data display selection mark  4  is not displayed on the display screen. 
   When the user has finished use of the TV phone, in a STEP  2 - 13  the line is disconnected and the processing routine returns to STEP  2 - 01 . 
     FIG. 6  is a flow chart showing an answering phone function processing routine  3 . 
   When the answering phone function is selected from among the choices displayed on the display screen, first, in a STEP  3 - 01 , it is confirmed whether or not termination of the operation of the answering phone function has been selected. 
   Termination of the answering phone function can also be selected at any time after the answering phone function has been selected and under any and all circumstances, whether after message reproduction or during message reproduction. 
   When termination of the answering phone function is selected, the processing routine proceeds to STEP  1 - 01  in processing routine  1 , a list of choices for selecting the functions of the interactive communication apparatus  1  is displayed on the display screen and operation of the answering phone function is terminated. 
   When termination of the answering phone function is not selected, the processing routine proceeds to a STEP  3 - 02  and the interactive communication apparatus  1  displays for selection on the display screen a list of several of the most recent messages received as shown in  FIG. 19 . 
   As display of the record of messages received the name of the other party, the date and time of the call, the telephone number and so forth can be displayed from a previously registered correspondence between telephone numbers and other party names, from which any one record can be selected and the received data reproduced. 
   Next, in a STEP  3 - 03 , it is confirmed whether or not any one of the records of messages received has been selected, and if not, the processing routine proceeds to a STEP  3 - 04  and one of the records of messages received is selected. 
   When selection is finished, in a STEP  3 - 05  the interactive communication apparatus  1  acquires audio data from the reception data corresponding to the record of messages received that has been selected and reproduces that audio data at the speaker SP 1 .
