     SUMMARY OF THE INVENTION 
     Problems that the Invention is to Solve 
     In the case where an image to be displayed on a displaying portion of a portable terminal apparatus is output to an external displaying apparatus and is caused to be displayed thereon, when an event occurs such as arrival of electronic mail or a call, the image output to the external displaying apparatus is changed corresponding to the event. Therefore, viewers other than a user of the portable terminal apparatus can consequently view information on the event that is, for example, information on the transmission origin of the electronic mail or the call origin on the external displaying apparatus. 
     According to the technique described in Patent Document 1, when the large-size audio-visual apparatus (the external displaying apparatus) is caused to execute reproduction, a preliminary setting can be made to restrict data to be sent out to the external displaying apparatus such that display such as display of reception of electronic mail displayed on the display of the portable terminal apparatus is not displayed on an external display screen. 
     However, according to this technique, to distinguish open data to be displayed on the external displaying apparatus and viewed by the user with other viewers and private data that the user of the portable terminal apparatus would like to view by him/herself without displaying the private data on the external displaying apparatus from each other, a setting needs to be made to correlate in advance attribute information indicating whether each piece of data is private data or open data with the kind of the data (for example, received electronic mail, a reception event, or remaining battery power amount). Therefore, labor for this setting is necessary and the data to be sent out to the external displaying apparatus is automatically restricted based on the setting for the attribute information. Therefore, the user can not easily execute on site an operation to output or restrict an image corresponding to the circumstances where the other viewers are user&#39;s family members, user&#39;s friends, coworkers in user&#39;s workplace, or some other persons, or what image is currently displayed. 
     The present invention was conceived in view of the above circumstances and the object thereof is to provide a terminal apparatus that, in the case where an image is output to an external displaying apparatus and the external displaying apparatus is caused to display the image, is able to continue display of the same image on the external displaying apparatus even when the user executes an operation to cause another image to be displayed that the user does not want to show to the current viewers of the external displaying apparatus in response to arrival of a call, reception of electronic mail, etc. 
     Means to Solve the Problems 
     To solve the problems, a first technical means of the present invention is a terminal apparatus capable of outputting an image to an external displaying apparatus, comprising: a displaying portion; and a different-output control portion that, when the different-output control portion detects an operation signal of a main body of the terminal apparatus during display of the image on the external displaying apparatus, continues the display of the image on the external displaying apparatus and executes different-output control to display on the displaying portion another image that is different from the image. 
     A second technical means of the present invention is the terminal apparatus as defined in the first technical means, further comprising: an external operation signal receiving portion that receives an external operation signal from the external displaying apparatus; and an operation origin determining portion that determines an operation origin from a result of determining which one of the external operation signal and the operation signal is detected, wherein the different-output control portion executes the different-output control when an operation origin determined by the operation origin determining portion is the operation signal during the display of the image on the external displaying apparatus. 
     A third technical means of the present invention is the terminal apparatus as defined in the second technical means, wherein the external operation signal is a remote control operation signal received through the external displaying apparatus from a remote controller to control the external displaying apparatus. 
     A fourth technical means of the present invention is the terminal apparatus as defined in any one of the first to third technical means, wherein the different-output control portion executes the different-output control when the different-output control portion detects as the operation signal any one of an input signal of an operation key, a signal indicating detection of moving of the terminal apparatus, and a signal indicating detection of variation of a physical shape of the terminal apparatus. 
     EFFECT OF THE INVENTION 
     According to the terminal apparatus of the present invention, in the case where the terminal apparatus outputs the image to the external displaying apparatus and causes the external displaying apparatus to display the image, even when the user executes an operation to cause another image to be displayed that the user does not want to show to the current viewers of the external displaying apparatus due to arrival of a call, reception of electronic mail, etc., the display of the image on the external displaying apparatus is enabled to continue.

     MODES FOR CARRYING OUT THE INVENTION 
     A terminal apparatus according to the present invention is able to output an image to an external displaying apparatus. A portable terminal apparatus will be taken as the terminal apparatus. However, portability is not indispensable to the terminal apparatus. An apparatus capable of receiving a call and electronic mail will be taken as an example as the portable terminal apparatus. However, this apparatus may have no function of transmitting and receiving a call or electronic mail. The terminal apparatus will be described taking a television apparatus (hereinafter, simply “TV”) as an example of the external displaying apparatus. However, the external displaying apparatus only has to be provided with a displaying portion to display an image and a communicating portion to communicate with the portable terminal apparatus, and may be a simple monitor, a digital photo frame, etc. 
     A connection using an HDMI (High-Definition Multimedia Interface) cable will be exemplified as the connection to output an image. However, various connecting methods may be employed each capable of outputting an image from the portable terminal apparatus to the external displaying apparatus such as the TV, such as a cable connection using i.LINK (a registered trademark) and a wireless connection such as Bluetooth (a registered trademark) or a wireless LAN (Local Area Network). Even under the HDMI standard, etc., the terminal apparatus is able to be adapted to transmit image data or a CEC (Consumer Electronics Control) command as a wireless signal by simultaneously employing a wireless connection standard such as a wireless LAN standard. 
       FIG. 1  is a diagram of an exemplary configuration of a display system including the portable terminal apparatus according to an embodiment of the present invention and the TV connected to the portable terminal apparatus. The display system exemplified in  FIG. 1  includes the portable terminal apparatus  1  and the TV  4  that are connected to each other by an HDMI cable  3 . The TV  4  is attached with a TV remote controller  5  that is a remote controller for the TV  4 . 
     In addition to a control portion  10  that controls the whole portable terminal apparatus  1 , the portable terminal apparatus  1  includes a communicating portion  11 , a microphone  12 , a speaker  13 , a displaying portion  14 , an external AV output portion  15 , a ROM (Read Only Memory)/RAM (Random Access Memory) portion  16 , an operation input portion  17 , and an external operation input communicating portion  18 . 
     The communicating portion  11  executes communication with a base station or a relaying station. The microphone  12  inputs a sound from a user during a call, etc. The speaker  13  outputs a sound, etc., of the counterpart during a call received by the communicating portion  11 . The displaying portion  14  displays an image indicated by image data output from an internal output data producing portion  22  described later. The external AV output portion  15  is an interface (I/F) to output the image data to the TV  4  through a TMDS (Transition Minimized Differential Signaling) line of the HDMI cable  3 . The image data is data output from an external output data producing portion  23  described later. The ROM/RAM portion  16  has programs to be executed by the control portion  10 , setting information, etc., stored therein. 
     The operation input portion  17  has a group of operational keys and inputs an operation from the user by detecting pressing down of each operational key, transferring to the control portion  10  an operational signal that corresponds to the operational key, etc. The operational keys may be configured by a touch panel incorporated in the displaying portion  14 , and a key image displayed on the displaying portion  14 . 
     The external operation input communicating portion  18  is an I/F that receives a CEC command concerning an external operation transmitted from the TV  4  and transmits a CEC command to the TV  4  through a CEC line of the HDMI cable  3 . An “external operation” refers to a key operation on the TV remote controller or a key operation on an operation input portion disposed on the main body of the TV  4 . 
     The external operation input communicating portion  18  is an example of an external operation signal receiving portion that receives an external operation signal. An “external operation signal” is an operation signal such as a CEC command concerning the external operation from the TV  4  and is, for example, an operation signal such as a CEC command to change an image output by the portable terminal apparatus  1 . As above, the portable terminal apparatus  1  is able to receive the external operation signal from the TV  4  and is also able to change the image output according to the external operation signal. Not to mention, the external operation signal may be a signal transmitted to execute an operation other than that for changing the output image at the portable terminal apparatus  1 . 
     As described for the external operation, utilization of a remote control operation signal received from the TV remote controller  5  through the TV  4  to control the TV  4  as the external operation signal enables the user to execute the operation at hand. In addition to HDMI cable  3 , a connection method is applicable that enables an operation signal from the TV remote controller  5  to be received by the portable terminal apparatus  1  through the TV  4 , that is, that enables a command corresponding to so-called “remote control passing-through” to be transmitted from the TV  4  to the portable terminal apparatus  1 . 
     The control portion  10  includes an output destination determining/control portion  21 , the internal output data producing portion  22 , and the external output data producing portion  23 . The output destination determining/control portion  21  will be described later. 
     The internal output data producing portion  22  produces image data to be displayed on the displaying portion  14  and sound data to be output to the speaker  13 , reading the programs and the setting information from the ROM/RAM portion  16  when necessary, and outputs the image data and the sound data respectively to the displaying portion  14  and the speaker  13 . 
     The internal output data producing portion  22  produces: contents of a UI (User Interface) image to be displayed on the displaying portion  14  of the portable terminal apparatus  1 , other still images such as photographs stored in the portable terminal apparatus  1 , and moving images (video images); and image data such as a One-Seg video image acquirable using the portable terminal apparatus  1  through the communicating portion  11 , etc., and a WEB image, and the portion  22  outputs the contents and the image data to the displaying portion  14 . The internal output data producing portion  22  produces sound data such as sounds accompanying these images and music contents stored in the portable terminal apparatus  1 , and outputs the sound data to the speaker  13 . 
     The external output data producing portion  23  produces image data (and sound data) to be output to the TV  4  reading the programs and the setting information from the ROM/RAM portion  16  when necessary, and outputs the image data (and the sound data) to the external AV output portion  15 . In this manner, incorporation of mainly the external output data producing portion  23  and the external AV output portion  15  in the portable terminal apparatus  1  enables the portable terminal apparatus  1  to output an image (and a sound) to the TV  4  through the HDMI cable  3 . 
     Similarly to the objects for the internal output data producing portion  22  to output, the external output data producing portion  23  produces: contents of a UI image, other still images, and a moving image; and image data such as a One-Seg video image and a WEB image. The external output data producing portion  23  outputs the contents and the image data to the external AV output portion  15 . The external output data producing portion  23  produces sound data such as sounds accompanying these images and music contents stored in the portable terminal apparatus  1 , and outputs the sound data to the external AV output portion  15 . The TV  4  only has to additionally include a sound output apparatus such as a speaker or a connecting terminal to an external speaker to enable the TV  4  to also output the sound data. 
     The portable terminal apparatus  1  includes a following different-output control portion described below as a main characteristic of the present invention. When the different-output control portion detects an operation signal of a portable terminal apparatus main body (hereinafter, “internal operation signal”) such as a signal of an operation being input using an operational key on the operation input portion  17  during display of an image from the portable terminal apparatus  1  on the TV  4 , the different-output control portion continues the display of the image on the TV  4  and executes different-output control to display on the displaying portion  14  another image that is different from the image (an image presenting information that is different from the information displayed on the TV  4 ). In this different-output control, the different image to be displayed on the displaying portion  14  is basically an image that is applied with a process indicated by the internal operation signal, and is a different output from the image that is continuously displayed on the TV  4 . An easy operation enables an image corresponding to the operation to be instantly displayed on the displaying portion  14 , and enables the display on the TV  4  to have a content that is different from that of the display on the displaying portion  14 . 
     As above, in case the portable terminal apparatus  1  includes an external operation signal receiving portion (a portion corresponding to a receiving portion in the external operation input communicating portion  18 ) which is able to receive an external operation signal, the control portion  10  needs to determine an operation origin to execute the different-output control. 
     Therefore, the portable terminal apparatus  1  includes an operation origin determining portion that determines an operation origin by determining which one of an external operation signal and an internal operation signal is detected. An example will be taken for description where the operation origin determining portion determines an operation origin based on a signal input thereinto. However, the operation origin determining portion may be adapted to determine an operation origin based simply on an input path, etc., of the operation signal (for example, by separating input terminals of the output destination determining/control portion  21  and determining from which terminal the operation signal is input). 
     The output destination determining/control portion  21  is an example of a portion that includes the above different-output control portion and this operation origin determining portion. The output destination determining/control portion  21  determines whether an operation origin is the TV  4  or the portable terminal apparatus  1  main body based on whether the signal is an external operation signal or an internal operation signal, and executes the different-output control. When the operation origin determined is the main body such as the operation input portion  17 , the output destination determining/control portion  21  continues the display of the image on the TV  4  and displays on the displaying portion  14  another image that is different from the image. 
     As above, according to the portable terminal apparatus  1 , in the case where the portable terminal apparatus  1  outputs an image to the TV  4  and causes the TV  4  to display the image, even when an operation is executed to display another image that a user does not want to show to the current viewers of the TV  4  due to arrival of a call, reception of electronic mail, etc., the display of the image on the TV  4  is able to be continued. When the user changes an image to be output watching the TV  4 , the user is able to execute the change using an operation for the TV  4  on the TV remote controller  5 , etc. 
     Even when the portable terminal apparatus  1  is adapted to include no external operation signal receiving portion, that is, when the portable terminal apparatus  1  does not include the operation origin determining portion, the above different-output control is executable. Therefore, even in the case where the portable terminal apparatus  1  is adapted to be able to receive no external operation signal and to include no operation origin determining portion that is exemplified by the output destination determining/control portion  21 , when the portable terminal apparatus  1  outputs an image to the TV  4  and causes the TV  4  to display the image and a user has to execute an operation to display another image that the user does not want to show to the current viewers of the TV  4 , an easy and instantly executable operation on the portable terminal apparatus  1  enables only the displaying portion  14  to display the other image that corresponds to the operation continuing the display of the image on the TV  4 . 
     Specific examples of processes in the display system of  FIG. 1  will be described with reference to  FIGS. 2 to 8 . An overview of the specific examples will be first described with reference to  FIGS. 2 to 6 .  FIG. 2  is a diagram of an example of an operation and display of the time when a connection is started and that of the time when a television remote control is operated in the display system of  FIG. 1 .  FIG. 3  is a diagram of an example of an operation and display of the time when the portable terminal apparatus is operated and that of the time when the television remote control is operated in the display system of  FIG. 1 .  FIGS. 4 and 5  are flowcharts for explaining an example of a process procedure that corresponds to the examples of the operation and the display of  FIGS. 2 and 3 .  FIG. 6  is a schematic diagram of a frame structure of a CEC command transmitted and received between the portable terminal apparatus and the TV in the process procedures of  FIGS. 4 and 5 . 
     The portable terminal apparatus  1  and the TV  4  are connected to each other by the HDMI cable  3  as represented by a state I of  FIG. 2 . At this time, the portable terminal apparatus  1  detects the connection (step S 1 ). Next, the internal output data producing portion  22  automatically produces (or reads) a UI image  22   a  to select an output content and displays the UI image  22   a  on the displaying portion  14  of the portable terminal apparatus  1  (step S 2 ). Control may be employed for a predetermined user operation on the portable terminal apparatus  1  to display the UI image  22   a  on the displaying portion  14 . However, in this case, restriction is necessary to cause an operation signal generated by the predetermined user operation and the internal operation signal to differ from each other or to cause the different-output control to be not executed until the control by the predetermined user operation is completed. 
     At step S 2 , the external output data producing portion  23  automatically produces (or reads) a UI image  23   a  that is equivalent to the UI image  22   a  (a UI image formed from the UI image  22   a  by matching the size and the resolution of the UI image  22   a  with those of the displaying portion of the TV  4 ) and delivers the UI image  23   a  to the external AV output portion  15 . Thereby, the external AV output portion  15  outputs the UI image  23   a  to the TV  4  through the HDMI cable  3  (step S 3 ) and the TV  4  displays the UI image  23   a  on the displaying portion thereof. An image such as the UI image  23   a  produced by and input from the external output data producing portion  23  may be displayed after being applied with a scaling process such as enlarging by the TV  4 . At step S 2 , etc., an output state of the displaying portion  14  and the TV  4  (at step S 2 , an output state where the displaying portion  14  and the TV  4  are in their equivalently outputting states) is recorded in the ROM/RAM portion  16  and is managed such that the current state is able to be grasped. States to be recorded can be a differently outputting state described later in addition to the equivalently outputting state at step S 2 . 
     It is assumed that a remote control key is operated by the user on the TV remote controller  5  from the state I (step S 4 ). In this case, the procedure will be described assuming that a “Down” key for remote control passing-through is operated as in the state II. In CEC under the HDMI standard, in addition to the Down key, various remote control keys such as an Up key, a Left key, a Right key, and an Exit key are transferable to a CEC-supporting apparatus connected to the TV  4  by remote control passing-through. 
     The TV  4  receives using its receiving portion for the remote control a remote control signal transmitted by pressing down of the Down key for remote control passing-through, interprets the remote control signal to be the Down key for remote control passing-through, and transmits a CEC command &lt;User Control Pressed&gt; [Down] to the portable terminal apparatus  1  through the HDMI cable  3  (step S 5 ). Thereafter, when a finger leaves this Down key, the TV  4  also receives this leaving, interprets this leaving to be leaving from the Down key, and transmits a CEC command &lt;User Control Released&gt; to the portable terminal apparatus  1  through the HDMI cable  3  (step S 6 ). 
     A CEC command has a frame structure including a start bit (S)  31 , a header block (Header Block)  32 , and a control command (Opecode)  33 , and a parameter (Parameter)  34  is added after the control command  33  when necessary, as exemplified by a CEC command  30  of  FIG. 6 . The header block  32  has a message transmission address (Initiator)  32   a  and a message reception address (Destination)  32   b  described therein as logical addresses. When the TV  4  receives a remote control operation signal from the TV remote controller  5 , the TV  4  sets its own logical address to be the message transmission address  32   a , sets a logical address of another CEC-supporting apparatus currently connected thereto to be the message reception address  32   b , and transmits CEC commands like those of steps S 5  and S 6 . A CEC-supporting apparatus: is able to determine the transmission origin of the message based on the message transmission address  32   a ; compares the message reception address  32   b  with its own transmission origin; and, thereby, is able to recognize whether the control command  33  following the address  32   b  is a command directed to the CEC-supporting apparatus itself. 
     The portable terminal apparatus  1  compares the message reception address  32   b  with its own logical address and, when these addresses coincide with each other, receives the CEC commands of steps S 5  and S 6  using the external operation input communicating portion  18 . The output destination determining/control portion  21  interprets the message transmission address  32   a  of each of the CEC commands and detects that the CEC command indicates the external operation signal from the TV, that is, the pressing down of the TV remote control key (step S 7 ). 
     Next, the control portion  10  interprets from the control command  33  the signal to be an external operation signal indicating the pressing down of the Down key, and accordingly informs the output destination determining/control portion  21  therein. The output destination determining/control portion  21  determines the TV  4  to be the output destination based on the fact that the signal is an external operation signal, and instructs the external output data producing portion  23  to produce a UI image  23   b  pointed by a cursor that is moved downward by one row from the UI image  23   a . The external output data producing portion  23  produces the UI image  23   b  and delivers the UI image  23   b  to the external AV output portion  15  (step S 8 ). Thereby, the external AV output portion  15  outputs the UI image  23   b  to the TV  4  through the HDMI cable  3  (step S 9 ) and the TV  4  displays the UI image  23   b  on its own displaying portion. 
     At step S 8 , the output destination determining/control portion  21  determines the reception of the external operation signal and, therefore, also sends to the internal output data producing portion  22  an instruction to produce a UI image  22   b  that is equivalent to that of the TV  4 . The internal output data producing portion  22  produces the UI image  22   b  according to the instruction and outputs the UI image  22   b  to the displaying portion  14  to cause the displaying portion  14  to display the UI image  22   b . At step S 8 , the state of the above process (the equivalently output state) is managed as it is recorded in the ROM/RAM portion  16  such that the current state is able to be grasped. 
     It is assumed that an operation is executed on the operation input portion  17  of the portable terminal apparatus  1  from this state I or II (step S 10 ). In this case, the procedure will be described assuming that an operation to display an electronic mail reception box is executed as in the state III. This operation may be regarded as an operation automatically executed in response to the reception of the electronic mail, or may be an operation executed by the user who desires to check the past electronic mail. 
     When the operation input portion  17  receives the operation to display the electronic mail reception box, the operation input portion  17  delivers to the control portion  10  an internal operation signal that indicates its process content. Thereby, the output destination determining/control portion  21  detects that the signal is not an external operation signal and is an internal operation signal, that is, detects the pressing down of an operation key of the portable terminal apparatus  1  (step S 11 ). 
     The control portion  10  interprets the operation content (in this example, the displaying of the electronic mail reception box) from the internal operation signal and delivers the operation content to the output destination determining/control portion  21  therein. The output destination determining/control portion  21  determines that the output destination is the displaying portion  14  of the portable terminal apparatus  1  from the fact that the signal is an internal operation signal, and instructs the internal output data producing portion  22  to produce a UI image  22   c  that displays the electronic mail reception box. The internal output data producing portion  22  produces the UI image  22   c  and delivers the UI image  22   c  to the displaying portion  14  (step S 12 ). Thereby, the displaying portion  14  displays the UI image  22   c  that includes information handled by the user as confidential information. 
     At step S 12 , the output destination determining/control portion  21  determines the reception of the internal operation signal. However, the output destination determining/control portion  21  instructs the external output data producing portion  23  to output the image as before (the UI image  23   b ). Naturally, when a moving image is output, an instruction is issued to continue the output of the moving image. Thereby, the external output data producing portion  23  and the external AV output portion  15  continue outputting their previous images (step S 13 ). 
     At step S 12 , the state of the above process is recorded in the ROM/RAM portion  16  and is managed such that the current state is able to be grasped. Due to the transition from the state I or II to the state III, the state only has to be updated to the differently outputting state where the displaying portion  14  and the TV do not execute the equivalent outputting. 
     The case where the operation of the portable key is executed at step S 10  can be the time when viewing is shifted to viewing of data that the user does not want to show to other persons (private data). The private data can be, for example, (1) data to manage the user him/herself of the portable terminal apparatus  1 , (2) data related to the taste of the user him/herself, (3) data relating to the form of thought or the form of action of the user him/herself, (4) data only for the user him/herself to use, and (5) data of the record of past actions of the user him/herself (operation record/communication record). 
     The data of (1) can be the name, the telephone number, the electronic mail address of the user him/herself. The data of (2) can be, for example, specific photographs, specific moving images, specific music data, specific electronic book data, specific downloaded applications, data of a pedometer, a record of meals, a schedule, and specific documents. The data of (3) can be electronic mail and data folder names (mail box names). The data of (4) can be an address book and a record of calls and messages in a telephone answering portion. The data of (5) can be a call history, a use history and balance information of electronic money, etc., and a game record, in addition to a website browsing history, a shopping history, and book marks. 
     When the user desires to display such private data on the displaying portion  14 , the user executes the operation on the operation input portion  17  and, thereby, is able to display the private data only on the displaying portion  14  without displaying the private data on the TV  4 . For example, it is assumed that, when electronic mail reception occurs during viewing of the open data on TV  4  with the portable terminal apparatus  1  connected thereto, the user operates the portable terminal apparatus  1  main body to try to view electric mail received holding the portable terminal apparatus  1  in his/her hand. The operation of the portable terminal apparatus  1  main body causes only the displaying portion  14  to display the private data and maintains the display output to the TV  4 . Therefore, the private data is able to be prevented from being displayed on the TV  4  and viewed by other persons. 
     Whether a piece of data corresponds to private data differs depending on a viewer of the TV  4 . However, the user is able to determine the data to be private data and set the private data to be a different output when necessary. Therefore, a setting to determine whether a piece of data is private data does not need to be stored inside the portable terminal apparatus  1 . 
     On the other hand, when data that may be open is viewed, the user only has to operate the portable terminal apparatus  1  using the TV remote controller  5  as described at step S 4 . 
     It is assumed that an operation on the TV remote controller  5  is accepted from the state III (step S 14 ). In this case, when it is assumed that the pressing down of the Down key is accepted as in the state IV, the same processes as those at steps S 5  to S 9  (steps S 15  to S 19 ) are executed. 
     However, at step S 18 : the TV  4  displays a UI image  23   d  pointed by the cursor that is moved downward by one row from the UI image  23   b ; the displaying portion  14  also displays a UI image  22   d  pointed by the cursor that is moved downward by one row from the UI image  22   c ; and the state is updated from the differently outputting state to the equivalently outputting state. 
     Next, a flow of processes in the portable terminal apparatus  1  will be described with reference to  FIGS. 7 and 8 .  FIG. 7  is a flowchart for explaining an exemplary process executed for occurrence of an event of a connection or a disconnection to/from the TV and executed by the portable terminal apparatus in the display system of  FIG. 1 .  FIG. 8  is a flowchart for explaining an exemplary process executed for occurrence of an event of a user operation and executed by the portable terminal apparatus in the display system of  FIG. 1 . 
     The event of a connection or a disconnection to/from the TV  4  will be described with reference to  FIG. 7 . The control portion  10  of the portable terminal apparatus  1  detects whether the event of a connection or a disconnection occurs concerning the connection to the TV  4  (step S 21 ). When the event occurs, the control portion  10  determines whether the event is an event of an HDMI connection to the TV  4  (step S 22 ). When the event of a connection or a disconnection is an event that “a connection is detected of the external operation input communicating portion  18  to the TV  4  through the HDMI cable  3 ”, it is able to be determine that the event is an event of an HDMI connection to the TV  4 . 
     When the determination result is YES at step S 22 , it is recorded in the ROM/RAM portion  16  that the output destination determining/control portion  21  is in the equivalently outputting state (step S 23 ). The output destination determining/control portion  21  selects the TV  4  as an output destination. The external output data producing portion  23  and the external AV output portion  15  output an image (a video image) equivalent to the image on the displaying portion  14  through the HDMI cable  3  (step S 24 ). After step S 24 , the procedure returns to step S 21 . Due to these processes, the state becomes a display state like, for example, the state I of  FIGS. 2 and 4 . Any order of steps S 23  and S 24  may be employed. 
     On the other hand, when the determination result is NO at step S 22 , the control portion  10  determines whether the event is an event of a disconnection of the HDMI connection to the TV  4  (step S 25 ). When the event of a connection or a disconnection detected at step S 21  is an event that “the external operation input communicating portion  18  connected to the TV  4  through the HDMI cable  3  detects unplugging of the HDMI cable  3  at the portable terminal apparatus  1  or the TV  4 ”, it is able to be determined that the event is an event of HDMI disconnection from the TV  4 . 
     When the determination result is YES at step S 25 , no output of any image to the TV  4  is necessary and, therefore, according to an instruction of the output destination determining/control portion  21 , the external output data producing portion  23  and the external AV output portion  15  discontinue (stop) their output of the images through the HDMI cable  3  (step S 26 ). This makes no change to the content of the display on the displaying portion  14 . Thereafter, the procedure returns to step S 21 . 
     When the determination result is NO at step S 25 , the event is another event of a connection or a disconnection such as a connection or a disconnection to/from the TV  4  or another apparatus at a USB (Universal Serial Bus) cable. Therefore, the control portion  10  executes a process that corresponds to the event (step S 27 ) and the procedure returns to step S 21 . This makes no change to the content of the display on each of the displaying portion  14  and the displaying portion of the TV  4 . 
     Next, an event of a user operation will be described with reference to  FIG. 8 . The output destination determining/control portion  21  determines whether the portion  21  receives a remote control key (an external operation signal) (step S 31 ). When it is determined that the portion  21  receives the signal (when the determination result is YES), the output destination determining/control portion  21  determines whether the state is the equivalently outputting state based on the record in the ROM/RAM portion  16  (step S 32 ). When it is determined that the state is not the equivalently outputting state (when the determination result is NO), the output destination determining/control portion  21 : updates the state of the ROM/RAM portion  16  to the equivalently outputting state; issues to the internal output data producing portion  22  an instruction to discontinue the image (video image) that is displayed on the displaying portion  14  until this time point; and discontinues the production and the outputting of the image that is displayed until this time point (step S 34 ). 
     When the determination result is YES at step S 32  and after the process of step S 34 , the output destination determining/control portion  21  instructs the internal output data producing portion  22  and the external output data producing portion  23  to execute a process and outputting corresponding to the remote control key. The internal output data producing portion  22  executes the process and the outputting for the displaying portion  14 , and the external output data producing portion  23  and the external AV output portion  15  execute equivalent video image outputting through the HDMI cable  3  (step S 35 ). Any order of steps S 33  and S 34  may be employed. After the process of step S 35 , only when the determination result is NO at step S 32 , the process of step S 33  (the process of step S 34  is included in the process of step S 35 ) may be executed. After the process of step S 35 , the procedure returns to step S 31 . Due to these processes, the state becomes the display state like, for example, the state II of  FIGS. 2 and 4 . 
     On the other hand, when the determination result is NO at step S 31 , the output destination determining/control portion  21  determines whether an input of a key (a portable key) is executed on the operation input portion  17  (step S 36 ). When it is determined that no input is executed, the procedure returns to step S 31 . When it is determined that an input of a portable key is executed (when the determination result is YES at step S 36 ), the output destination determining/control portion  21  determines whether the state is the equivalently outputting state from the record in the ROM/RAM portion  16 , etc., (step S 37 ). When it is determined that the state is the equivalent outputting state (when the determination result is YES), the output destination determining/control portion  21  updates the state of the ROM/RAM portion  16  to the differently outputting state (step S 38 ). 
     When the determination result is NO at step S 37  and after the process of step S 38 , the output destination determining/control portion  21  receives the portable key and, therefore, the output destination determining/control portion  21  instructs the internal output data producing portion  22  to produce an image of the process and the outputting that correspond to the portable key (the internal operation signal). The displaying portion  14  displays the image (step S 39 ). In the process of step S 39 , the video image output to the TV  4  is maintained, that is, no video image reflecting the portable key is output to the TV. After the process of step S 39 , only when the determination result is YES at step S 37 , the process of step S 38  may be executed. After the process of step S 39 , the procedure returns to step S 31 . Due to these processes, the state becomes the display state like, for example, the state III of  FIGS. 3 and 5 . 
     According to the above processes, as a typical exemplary use, in the case where the content displayed on the displaying portion  14  of the portable terminal apparatus  1  is displayed on the display of the TV  4  connected to the portable terminal apparatus  1 , when the operation to display electronic mail received by the portable terminal apparatus  1  is executed on the operation input portion  17  of the portable terminal apparatus  1 , the displaying portion  14  of the portable terminal apparatus  1  at hand is able to be adapted to display the text of the electronic mail that is a new content and the display of the TV  4  connected thereto is able to be adapted not to display the text of the electronic mail that is the new content. Thereby, a user is able to refer to his/her secret information at hand (using the portable terminal apparatus  1 ) continuing showing the others the content originally displayed on the display. 
     As above, the portable terminal apparatus  1  according to the present invention has been described. However, the above different-output control portion may be adapted to execute the different-output control when the different-output control portion detects not only the input signal of the operation key but also either one of a signal indicating detection of moving of the portable terminal apparatus  1  and a signal indicating detection of variation of the physical shape of the portable terminal apparatus  1  as the internal operation signal. The different-output control portion may be adapted to execute the different-output control only when the different-output control portion detects any one of these three detections. Naturally, the different-output control portion may execute the different-output control only when the different-output control portion detects the moving or may execute the different-output control only when the different-output control portion detects the variation of the physical shape. 
     For the moving of the portable terminal apparatus  1 , a sensor such as, for example, an acceleration sensor, etc., is loaded thereon and only has to be adapted to detect the moving of the position, a disposition angle, etc. For example, a user is able to execute the different-output control by only taking up in the user&#39;s hand the portable terminal apparatus  1  put on a table by the user or by only an operation of holding the portable terminal apparatus  1  in the user&#39;s hand and shaking it. For the variation of the physical shape of the portable terminal apparatus  1 , a movable portion is disposed in the portable terminal apparatus  1  and only has to be adapted to be able to detect, for example, flip-opening, slide-opening, and a rotation of the displaying portion  14 . The different-output control is able to be executed when the user only causes such variation of the physical shape. 
     As above, the different-output control is executed in response to the moving of the portable terminal apparatus  1  or the variation of the physical shape thereof and, thereby: it is able to more easily and instantly be determined that the operation origin is the portable terminal apparatus  1 ; and the secret information (the private data) is able to be displayed on the portable terminal apparatus  1  maintaining the display on the TV  4  as it is. Furthermore, such an action of the user as holding the portable terminal apparatus  1  in his/her hand or causing a change to the physical shape to be able to see the screen of the displaying portion  14  is a natural action executed to view the data on the portable terminal apparatus  1 . Therefore, the display on the displaying portion  14  is able to be automatically executed by this natural action and display different from that on the displaying portion  14  is able to be executed on the TV  4 . Therefore, the present invention is highly beneficial. 
     As above, the present invention has been described on the premise that the TV  4  is one that is connected to the portable terminal apparatus  1 . However, even when a plurality of external displaying apparatuses such as the TV  4  are connected to the portable terminal apparatus  1 , the present invention is applicable thereto. 
     The present invention has also been described on the premise that the data output from the portable terminal apparatus  1  to the external displaying apparatus such as the TV  4  is the image data (and the sound data). However, the present invention is also applicable to the case where only the sound data is output from the portable terminal apparatus to an external sound output apparatus. In this case, control to mute the sound only has to be executed instead of the different-output control and, preferably, the portable terminal apparatus  1  is adapted to be able to change the sound to output in response to an external operation signal from the external sound output apparatus similarly to the case of the image. 
     As above, the portable terminal apparatus according to the present invention has been described. However, the portable terminal apparatus is able to be adapted to execute control to cause the display of an image on the TV  4  not to be displayed not maintaining the display of the image on the TV  4  as it is, as another example where the differently outputting is executed when an internal operation signal is detected. Such discontinuation control will be described taking an example of the display system of  FIG. 1  that transmits and receives the CEC command of  FIG. 6 . 
     The portable terminal apparatus  1  of the example includes a discontinuation control portion as follows. When the discontinuation control portion detects an internal operation signal such as an operation input using the key on the operation input portion  17  during display on the TV  4  of an image from the portable terminal apparatus  1 , the discontinuation control portion executes control to discontinue the display (not to display) on the TV  4  of the image from the portable terminal apparatus  1 . Hereinafter, this control is referred to as “non-display control”. This control will be described taking an example of an input using a key on the operation input portion as an internal operation signal. According to the non-display control, when accepting an operation of an operational key on the operation input portion  17 , the discontinuation control portion is able to cause the display on the TV  4  not to be displayed. An easy operation is able to instantly cause the display on the TV  4  not to be displayed. 
     Next, an example will be taken of a method of setting the image from the portable terminal apparatus  1  not to be displayed on the TV  4 . The discontinuation control portion may discontinue the output of the image from the portable terminal apparatus  1  to the TV  4  as the non-display control. The discontinuation of the output is able to be realized by an event such as producing no image data of the control portion  10  (the output destination determining/control portion  21 ) using the external output data producing portion  23 , causing the output to the external AV output portion  15  to be discontinued using the external output data producing portion  23 , or causing the output to the HDMI cable  3  to be discontinued using the external AV output portion  15 . Due to this discontinuation of the output, no image is transmitted from the portable terminal apparatus  1  to the TV  4  and, therefore, the image from the portable terminal apparatus  1  is not displayed on the TV  4 . 
     The discontinuation control portion outputs a control signal capable of causing the TV  4  to display no image from the portable terminal apparatus  1  (a control signal capable of discontinuing the display of the image) as the non-display control, as another method. Such a control signal can be, for example, a control signal to turn off the power of the TV  4  and a control signal to switch an input source of the TV  4  to a source other than the portable terminal apparatus  1 . The control portion  10  (the output destination determining/control portion  21 ) only has to produce such a control signal and output the control signal to the TV  4  through the external operation input communicating portion  18 . When this method is employed, preferably, the output of the image from the portable terminal apparatus  1  to the TV  4  is simultaneously discontinued as the non-display control. When two-way communication is enabled not through the HDMI cable  3  but through another path, the portable terminal apparatus  1  is able to transmit the control signal to the TV  4 . 
     As above, when the portable terminal apparatus  1  is provided with the external operation signal receiving portion (a portion corresponding to the receiving portion in the external operation input communicating portion  18 ) and the portable terminal apparatus  1  is able to receive an external operation signal, the control portion  10  needs to determine the operation origin to execute the non-display control. 
     To do the above, the portable terminal apparatus  1  includes the operation origin determining portion that determines the operation origin by determining which of the external operation signal and the internal operation signal is input thereinto. An example will be taken and described where the operation origin determining portion determines the operation origin based on the signal input thereinto. However, the operation origin determining portion may be adapted to determine the operation origin based simply on the input path of the operation signal (for example, by separating input terminals of the output destination determining/control portion  21  and determining from which terminal the operation signal is input). 
     The output destination determining/control portion  21  is an example of a portion that includes the above discontinuation control portion and this operation origin determining portion. The output destination determining/control portion  21  determines whether the operation origin is the TV  4  or the portable terminal apparatus  1  main body by determining whether the signal is an external operation signal or an internal operation signal, executes the non-display control, and executes control to realize the non-display on the TV  4  when the operation origin determined is the operation input portion  17 . 
     As described above, according to the portable terminal apparatus  1  in the example that is able to execute the non-display control, in the case where an image is output from the portable terminal apparatus  1  to the TV  4  and is displayed on the TV  4 , when another image that the user does not want to show to the current viewers of the TV  4  is displayed in response to arrival of a call, reception of electronic mail, or switching of the image, an easy and instantly executable operation on the portable terminal apparatus  1  is able to easily, quickly, and on site discontinue the display of the other image on the TV  4 . When the user changes the image to be output watching the TV  4 , an operation using the TV remote controller  5 , etc., for the TV  4  enables the execution of the change. 
     When the portable terminal apparatus  1  is configured to include no external operation signal receiving portion, that is, the above operation origin determining portion, the above non-display control is executable. Therefore, even with the portable terminal apparatus  1  adapted to be able to receive no external operation signal and to include no operation origin determining portion that is exemplified by the output destination determining/control portion  21 , in the case where an image is output from the portable terminal apparatus  1  to the TV  4  and is displayed on the TV  4 , when another image is displayed on the TV  4  that the user does not want to show to the current viewers of the TV  4 , an easy and instantly executable operation on the portable terminal apparatus  1  easily, quickly, and on site enables discontinuation of the display of the other image on the TV  4 . 
     A specific example of processes in the display system of  FIG. 1  adapted to be able to execute the non-display control will be described with reference to  FIGS. 9 to 12 . An overview of the specific example will first be described with reference to  FIGS. 9 ,  10 , and  6 .  FIG. 9  is a diagram of another example of the operation and the display of the time when a connection is started, that of the time when the TV remote control is operated, and that of the time when the portable terminal apparatus is operated in the display system of  FIG. 1 .  FIG. 10  is a flowchart for explaining an example of a process procedure that corresponds to the example of the operation and the display of  FIG. 9 .  FIG. 6  is also a schematic diagram of a frame structure of a CEC command transmitted and received between the portable terminal apparatus and the TV in the process procedures of  FIG. 10 . 
     The portable terminal apparatus  1  and the TV  4  are connected to each other by the HDMI cable  3  as represented by a state V of  FIG. 9 . At this time, the portable terminal apparatus  1  detects the connection (step S 51 ). Next, the internal output data producing portion  22  automatically produces (or reads) the UI image  22   a  to select output contents and displays it on the displaying portion  14  of the portable terminal apparatus  1  (step S 52 ). Control may be employed for a predetermined user operation on the portable terminal apparatus  1  to display the UI image  22   a  on the displaying portion  14 . However, in this case, a restriction is necessary for the non-display control not to be executed until the time of the predetermined user operation. 
     At step S 52 , the external output data producing portion  23  automatically produces (or reads) the UI image  23   a  that is equivalent to the UI image  22   a  and delivers the UI image  23   a  to the external AV output portion  15 . Thereby, the external AV output portion  15  outputs the UI image  23   a  to the TV  4  through the HDMI cable  3  (step S 53 ) and the TV  4  displays the UI image  23   a  on the displaying portion thereof. An image such as the UI image  23   a  produced by and input from the external output data producing portion  23  may be displayed after being applied with a scaling process such as enlarging by the TV  4 . At step S 52 , the state of this process (at least presence or absence of any output to the displaying portion  14  and presence or absence of any output to the TV  4 ) is recorded in the ROM/RAM portion  16  and is managed such that the current state is able to be grasped. States to be recorded can be a TV-connected state, a TV-outputting state, and portable-displaying state, etc. 
     It is assumed that a remote control key is operated by the user on the TV remote controller  5  from this state V (step S 54 ). In this case, the procedure will be described assuming that the Down key for remote control passing-through is operated as in the state VI. As above, in CEC under the HDMI standard, various remote control keys are transferable to a CEC-supporting apparatus connected to the TV  4  by remote control passing-through. 
     The TV  4  receives using its receiving portion for the remote control a remote control signal transmitted by pressing down of the Down key for remote control passing-through and executes the same processes as those of steps S 5 , S 6 , and S 7  of  FIG. 4  (steps S 55 , S 56  and S 57 ). 
     Next, the control portion  10  interprets from the control command  33  the signal to be an external operation signal transmitted by the pressing down of the Down key, and accordingly informs the output destination determining/control portion  21  therein. The output destination determining/control portion  21  determines the TV  4  to be the output destination based on the fact that the signal is an external operation signal, and instructs the external output data producing portion  23  to produce a UI image  23   b  pointed by the cursor that is moved downward by one row from the UI image  23   a . The external output data producing portion  23  produces the UI image  23   b  and delivers it to the external AV output portion  15  (step S 58 ). Thereby, the external AV output portion  15  outputs the UI image  23   b  to the TV  4  through the HDMI cable  3  (step S 59 ) and the TV  4  displays the UI image  23   b  on its own displaying portion. 
     At step S 58 , the output destination determining/control portion  21  determines the reception of the external operation signal and, therefore, sends to the internal output data producing portion  22  an instruction to discontinue the production of the image or an instruction to discontinue its output to the displaying portion  14 . The internal output data producing portion  22  discontinues the display of the UI image  22   a  on the displaying portion  14  according to the instruction. Thereby, a black screen  22   e  is displayed and, therefore, unnecessary display is able to be stopped. Therefore, saving of power is facilitated. At step S 58 , the state of this process is recorded in the ROM/RAM portion  16  and is managed such that the current state is able to be grasped. The state only has to be updated from the portable-displaying state to a portable-displaying discontinuation state in response to the transition from the state V to the state VI. 
     As described at step S 58 , the portable terminal apparatus  1  may be adapted to include a main-body discontinuation control portion that discontinues display of an image (that is not limited to a same image as the image being output to the TV  4 ) on the displaying portion  14  when the operation origin determined is the TV  4 . This main-body discontinuation control portion is also able to be exemplified by the output destination determining/control portion  21 . As above, this discontinuation process is able to be executed by issuance of a production discontinuation instruction by the output destination determining/control portion  21  to the internal output data producing portion  22  or by issuance of an output discontinuation instruction thereby to the displaying portion  14  (and the speaker  13 ). The main-body discontinuation control portion is also applicable in a form thereof including the different-output control portion described with reference to  FIGS. 2 to 8 . 
     It is assumed that an operation is executed by the user on the operation input portion  17  of the portable terminal apparatus  1  from the state V or VI (step S 60 ). In this case, the procedure will be described assuming that an operation to display an electronic mail reception box is executed as in the state VII. This operation may be regarded as an operation automatically executed in response to reception of electronic mail, or may be an operation executed by the user who desires to check the past electronic mail. 
     When the operation input portion  17  receives the operation to display the electronic mail reception box, the operation input portion  17  sends to the control portion  10  an internal operation signal that indicates its process content. Thereby, the output destination determining/control portion  21  detects that the signal is not an external operation signal and is an internal operation signal, that is, detects the pressing down of an operation key of the portable terminal apparatus  1  (step S 61 ). 
     The control portion  10  interprets the operation content (in this example, the displaying of the electronic mail reception box) from the internal operation signal and sends the operation content to the output destination determining/control portion  21  therein. The output destination determining/control portion  21  determines that the output destination is the displaying portion  14  of the portable terminal apparatus  1  from the fact that the signal is an internal operation signal, and instructs the internal output data producing portion  22  to produce the UI image  22   c  that displays the electronic mail reception box. The internal output data producing portion  22  produces the UI image  22   c  and delivers it to the displaying portion  14  (step S 62 ). Thereby, the displaying portion  14  displays the UI image  22   c.    
     At step S 62 , the output destination determining/control portion  21  determines the reception of the internal operation signal and, therefore, sends an instruction to discontinue the production of the image or an instruction to discontinue the output to the external AV output portion  15 , to the external output data producing portion  23 . Thereby, the external output data producing portion  23  or the external AV output portion  15  discontinues its image output (video image output) (step S 63 ). 
     At step S 62 , the output destination determining/control portion  21  also determines reception of an internal operation signal and, therefore, instructs the external operation input communicating portion  18  to produce and output a next CEC command (a CEC message). It is assumed that this CEC command is a command including the logical address of the portable terminal apparatus  1  itself (the external operation input communicating portion  18  itself) as the message transmission address  32   a  and the logical address of the TV  4  as the message reception address  32   b  and employing &lt;Stanby&gt; (a command indicating turning off of the power) as its control command. The external operation input communicating portion  18  produces this CEC command and transmits the CEC command through the HDMI cable  3  (step S 64 ). Steps S 63  and S 64  discontinue the output of the image and the TV  4  receives this CEC command and turns off its own power (brings itself into a standby state). The displaying portion of the TV  4  displays a black screen  40 . 
     At step S 62 , the state of the above process is recorded in the ROM/RAM portion  16  and is managed such that the current state is able to be grasped. The state only has to be updated to the portable-displaying state and TV-outputting discontinued state in response to the transition from the state VI to the state VII. 
     By using the processes of steps S 58  and S 62  in parallel to each other, the output destination determining/control portion  21  determines an input origin (that is, the operation origin) of the operation signal, discontinues (or maintains the discontinuation of) the output to an output destination that is different from the operation origin, and outputs (or maintains outputting) to an output destination that coincides with the operation origin. 
     When the pressing down of the Down key on the TV remote controller  5  is accepted in the state VII, the TV  4  only has to turn on its own power, and the TV  4  and the portable terminal apparatus  1  only have to execute the processes of steps S 55  to S 59 . In this case, an UI image pointed by the cursor that is moved downward by one row from the UI image  22   c  is displayed on the displaying portion of the TV  4  instead of the UI image  23   b.    
     The case where the operation of the portable key is executed at step S 60  can be the time when viewing is transitioned to viewing of data that the user does not want to show to others (private data). In addition to the above (1) to (5), the private data can also be (6) image data itself used when the content of the image being output to the TV  4  is switched. The data of (6) can be image data itself of the time when the image being viewed on the web is switched to an image that the user does not want to show to the viewers in response to an operation of the user, and that of the time when the video image being received by One-Seg, etc., is switched to an image that the user does not want to show to the viewers in response to switching of the program or a change of the scene. 
     When the user has or is about to have no choice but to display such private data on the TV  4 , the user is able to cause the display on the TV  4  not to be displayed by executing the operation on the operation input portion  17 . It is assumed that, for example, in the case where the TV  4  and the portable terminal apparatus  1  are connected to each other and open data is being viewed on the TV  4 , when electronic mail reception occurs, the user holds the portable terminal apparatus  1  in his/her hand and operates the portable terminal apparatus  1  main body to view the electronic mail received. This operation on the portable terminal apparatus  1  main body automatically discontinues the output to the TV  4  (and outputs to the displaying portion  14  of the portable terminal apparatus  1 ) and, thereby, the private data is prevented from being displayed on the TV  4  and viewed by the others. 
     Whether a piece of data corresponds to private data also differs depending on the viewers of the TV  4 . However, the user is able to determine the above according to the case and set the data not to be displayed when necessary. Therefore, a setting to determine whether a piece of data is private data does not need to be stored inside the portable terminal apparatus  1 . 
     On the other hand, when data that may be made open is viewed, the user only has to operate the portable terminal apparatus  1  using the TV remote controller  5  as described for step S 54 . 
     Next, a flow of processes in the portable terminal apparatus  1  will be described with reference to  FIGS. 11 and 12 .  FIG. 11  is a flowchart for explaining another exemplary process executed for the occurrence of the event of the connection or the disconnection to/from the TV, and executed by the portable terminal apparatus in the display system of  FIG. 1 .  FIG. 12  is a flowchart for explaining another exemplary process for the occurrence of the event of the user operation, and executed by the portable terminal apparatus in the display system of  FIG. 1 . 
     The event of the connection or the disconnection to/from the TV  4  will be described with reference to  FIG. 11 . The control portion  10  of the portable terminal apparatus  1  detects whether the event of the connection or the disconnection occurs concerning the connection to TV  4  similarly to step S 21  of  FIG. 7  (step S 71 ). When the occurrence is detected, similarly to step S 22 , the control portion  10  determines whether the event is an event of an HDMI connection to the TV  4  (step S 72 ). 
     When the determination result is YES at step S 72 , the output destination determining/control portion  21  selects the TV  4  as an output destination, and the external output data producing portion  23  and the external AV output portion  15  output the image (a video image) through the HDMI cable  3  (step S 73 ). Following step S 73  or prior to step S 73 , the output destination determining/control portion  21  also selects the displaying portion  14  as another output destination and determines whether the state currently is the video image outputting discontinued state for the outputting to the displaying portion  14  from the record in the ROM/RAM portion  16  (step S 74 ). When it is determined that the state is the video image outputting discontinued state (when the determination result is YES), the output destination determining/control portion  21  controls the internal output data producing portion  22  to display an image (a video image) having the same content on the displaying portion  14  (step S 75 ). After step S 75 , the procedure returns to step S 71 . When the determination result is NO at step S 74 , this image is already being displayed and, therefore, the procedure returns to step S 71  without executing any process. These processes set the state to be, for example, the display state like the state V of  FIGS. 9 and 10 . 
     On the other hand, when the determination result is NO at step S 72 , similarly to step S 25  of  FIG. 7 , the control portion  10  determines whether the event is an event of disconnecting the HDMI connection to the TV  4  or not (step S 76 ). When the determination result is YES at step S 76 , the same process as that of step S 26  (step S 77 ) is executed and, when the determination result is NO at step S 76 , the same process as that of step S 27  (step S 78 ) is executed and the procedure returns to step S 71 . 
     Next, an event of a user operation will be described with reference to  FIG. 12 . The output destination determining/control portion  21  determines whether the output destination determining/control portion  21  receives the remote control key (the external operation signal) (step S 81 ). When it is determined that the output destination determining/control portion  21  receives the remote control key (when the determination result is YES), the output destination determining/control portion  21  executes a process of selecting the TV  4  as an output destination. The output destination determining/control portion  21  determines whether a video image is being output to the TV  4  from the record in the ROM/RAM portion  16 , etc., (step S 82 ). When it is determined that no video image is being output (when the determination result is NO), the output destination determining/control portion  21  instructs the external output data producing portion  23  to output a video image, etc., and the external output data producing portion  23  and the external AV output portion  15  executes video image output through the HDMI cable  3  (step S 83 ). 
     When the determination result is YES at step S 82  and after the process of step S 83 , the output destination determining/control portion  21  receives the remote control key and, therefore, executes a process of excluding the displaying portion  14  as an output destination. And that is, the output destination determining/control portion  21  determines whether any video image is currently output to the displaying portion  14  or not from the record in the ROM/RAM portion  16 , etc., (step S 84 ). When currently outputting (when the determination result is YES), the output destination determining/control portion  21  instructs the internal output data producing portion  22  to discontinue the video image output, etc., and the video image output on the displaying portion  14  is discontinued (step S 85 ). 
     When the determination result is NO at step S 84  and after the process of step S 85 , a process is executed corresponding to the remote control key that is the origin for which it is determined at step S 81  that the remote control key is received from this origin (a process of changing the video image) (step S 86 ) and the procedure returns to step S 81 . Due to this process, the state becomes the display state like, for example, the state VI of  FIGS. 9 and 10 . 
     On the other hand, when the determination result is NO at step S 81 , the output destination determining/control portion  21  determines whether key (a portable key) inputting is executed on the operation input portion  17  or not (step S 87 ). When the portable key inputting is not executed, the procedure returns to step S 81 . When the portable key inputting is executed (YES at step S 87 ), the output destination determining/control portion  21  executes a process of excluding the TV  4  as an output destination. And that is, the output destination determining/control portion  21  determines whether any video image is currently output to the TV  4  from the record in the ROM/RAM portion  16  or not (step S 88 ). When currently outputting (when the determination result is YES), the output destination determining/control portion  21  instructs the external output data producing portion  23  to discontinue the video image output, etc., and the external output data producing portion  23  and the external AV output portion  15  discontinue the video image output through the HDMI cable  3  (step S 89 ). As above, simultaneously with this process of step S 89 , the output destination determining/control portion  21  may instruct the external operation input communicating portion  18  to issue a control signal to turn off the power of the TV  4  and the power of the TV  4  may be turned off. 
     When the determination result is NO at step S 88  and after the process of step S 89 , the output destination determination/control portion  21  receives a portable key and, therefore, executes a process of adding the displaying portion  14  as an output destination. And that is, the output destination determining/control portion  21  determines whether any video image is currently output to the displaying portion  14  or not from the record in the ROM/RAM portion  16  (step S 90 ). When not currently outputting (when the determination result is NO), the output destination determining/control portion  21  instructs the internal output data producing portion  22  to output a video image, etc., and the video image output on the displaying portion  14  is executed (step S 91 ). 
     When the determination result is YES at step S 90  and after the process of step S 91 , a process is executed corresponding to the portable key that is the origin for which it is determined at step S 87  that the portable key is input (a process of changing the video image, etc.) (step S 86 ) and the procedure returns to step S 81 . Due to this process, the state becomes the display state like, for example, the state VII of  FIGS. 9 and 10 . 
     As above, the portable terminal apparatus  1  that executes the non-display control has been described. However, the above discontinuation control portion may be adapted to execute the different-output control when the discontinuation control portion detects not only the input signal of the operation key but also either one of a signal indicating the detection of the moving of the portable terminal apparatus  1  and a signal indicating the detection of the variation of the physical shape of the portable terminal apparatus  1  as an internal operation signal. The discontinuation control portion only has to be adapted to execute the non-display control when the discontinuation control portion executes anyone of these three cases of detection. Naturally, the discontinuation control portion may execute the non-display control only when the discontinuation control portion detects the moving or may execute the non-display control only when the discontinuation control portion detects the variation of the physical shape. The detection of the moving and the detection of the variation of the physical shape are as above. 
     As above, the non-display control is executed in response to the moving or the variation of the physical shape of the portable terminal apparatus  1  and, thereby, it is more easily and instantly determined that the operation origin is the portable terminal apparatus  1 . Therefore, the display on the TV  4  is able to be discontinued of the image from the portable terminal apparatus  1 . Furthermore, such an action of the user such as holding the portable terminal apparatus  1  in his/her hand or varying its shape to be able to view the screen of the displaying portion  14  is a natural actin to be conducted for viewing the data on the portable terminal apparatus  1 . Therefore, highly benefit is obtained because the image display on the TV  4  is able to be automatically discontinued with this natural action. 
     As above, an explanation has been done on the premise that the TV  4  is one that is connected to the portable terminal apparatus  1  capable of executing the non-display control. However, even when a plurality of external displaying apparatuses such as the TV  4  are connected to the portable terminal apparatus  1 , the non-display control is applicable thereto. 
     And the explanation has been done on the premise that the data output from the portable terminal apparatus  1  capable of executing the non-display control to the external displaying apparatus such as the TV  4  is the image data (and the sound data). However, the idea of the non-display control is also applicable to the case where only the sound data is output from the portable terminal apparatus to an external sound output apparatus. In this case, control to mute the sound only has to be executed instead of the non-display control and, preferably, the portable terminal apparatus  1  is adapted to be able to change the sound to output in response, to an external operation signal from the external sound output apparatus similarly to the case of an image.
