Description

  The present invention converts data (hereinafter referred to as “content data”) of an image and / or video (hereinafter referred to as “content”) into a video signal and has another device (hereinafter referred to as “hereinafter referred to as“ content data ”) having a display screen. The present invention relates to a portable terminal device that outputs to an external device), and particularly relates to a portable terminal device having a rotation mechanism.

  Some portable terminal devices such as mobile phones have a function of displaying content on a display screen of an external device by converting content data into a video signal and outputting the video signal to the external device.

  Specifically, when the video output terminal of the mobile terminal device and the video input terminal of the external device are connected by a video signal line, the mobile terminal device converts the content data into a video signal and converts the video signal to the external device. Can be output. When the video signal is input to the external device, the external device generates content data based on the input video signal and displays the content data on the display screen. Thereby, the portable terminal device realizes the above function.

  There are many types of portable terminal devices of this type in which the display unit is designed to be rectangular. In particular, in mobile phones, there are a large number of models in which the display unit is designed to be vertically long in a rectangular shape whose vertical length is longer than the horizontal length (hereinafter referred to as “vertically long”).

  The reason is as follows.

  That is, in the mobile phone, it is necessary to arrange the earpiece near the user's ear and the mouthpiece near the user's mouth. Therefore, in consideration of the size of the mobile phone, the mobile phone is generally designed to have a vertically long casing. Along with this, the display unit is preferably designed to be vertically long so that it can be suitably stored in a vertically long casing.

  On the other hand, the content is not limited to being vertically long, and there are many content that is horizontally long (a shape that is rectangular and whose vertical length is shorter than the horizontal length). Of course, it is appropriate to display the vertically long content on the vertically long display portion and the horizontally long content on the horizontally long display portion. Here, if the content is inappropriately displayed on the display unit (that is, the vertically long content is displayed on the horizontally long display unit, or the horizontally long content is displayed on the vertically long display unit), the content is the original size. There is a possibility that it is displayed on the display unit in a reduced state or partly disappears from the display unit.

  Therefore, in the mobile terminal device, it is necessary to appropriately display the content on the display unit (that is, display the vertically long content on the vertically long display unit or display the horizontally long content on the horizontally long display unit).

  By the way, in recent mobile terminal devices, there are models having a function of receiving a television broadcast (digital broadcast represented by analog broadcast and / or one-segment broadcast). Then, in order to appropriately display the TV broadcast video on the display unit, the mobile phone disclosed in Non-Patent Document 1 stores the display unit with the content display surface exposed, and is rotatable with respect to the apparatus main body. A rotating mechanism for maintaining the supported housing in a rotational state of at least two different angles;

In the mobile terminal device (mobile phone) disclosed in Non-Patent Document 1, the display unit is vertically long, but the received television broadcast is displayed on the display unit as a horizontally long image. Therefore, the portable terminal device disclosed in Non-Patent Document 1 makes the display unit substantially horizontally long by rotating only the housing portion including the display unit. Thereby, the received television broadcast video can be appropriately displayed on the display unit.
SoftBank Mobile 905SH Instruction Manual (May 2006, 2nd edition issued)

  By the way, in the portable terminal device disclosed in Non-Patent Document 1, when the video signal obtained by converting the content data is output to the outside, the video signal is displayed according to the attitude of the housing portion including the display unit. Cannot be changed from a predetermined state. In other words, in the portable terminal device disclosed in Non-Patent Document 1, when content is displayed on the display screen of the external device, the content is displayed on the display screen of the external device according to the attitude of the housing portion including the display unit. Content cannot be rotated automatically.

  Therefore, in the mobile terminal device disclosed in Non-Patent Document 1, when the content displayed on the display screen of the external device is rotated, a specific setting operation by the user (setting by setting menu, setting by setting button, etc.) Is done. In this case, in order to control the rotation of the content displayed on the display screen of the external device, the user rotates the content by a desired angle with respect to the mobile terminal device by the specific setting operation. It is necessary to instruct. For this reason, the control of the rotation of the content displayed on the display screen of the external device in the mobile terminal device disclosed in Non-Patent Document 1 becomes complicated for the user.

  In addition, when the user performs rotation control by giving the above instruction to the mobile terminal device, the user needs to perform rotation control after generally grasping the desired angle. In this case, the user cannot visually grasp the desired angle, and as a result, it is difficult to intuitively control the rotation of the content displayed on the display screen of the external device. Problem occurs.

  The present invention has been made in view of the above-described problems, and its object is to display content on a display screen of an external device when the content is displayed on the display screen of the external device in a portable terminal device having a rotation mechanism. It is an object of the present invention to provide a mobile terminal device that can easily and intuitively control the rotation of content.

  In order to solve the above-described problem, the portable terminal device according to the present invention stores display means for displaying at least one of an image and video as content, with at least the content display surface exposed, and rotates with respect to the device main body. A housing that is supported, a rotation mechanism that maintains the housing in a rotational state at at least two different angles, and a rotation state detection unit that detects a rotation state of the housing maintained by the rotation mechanism; The content rotation processing means for rotating the content displayed on the display means and the content rotated by the content rotation processing means are converted into a video signal according to the detection result by the rotation state detecting means. Video signal output means for outputting to an external device.

  Further, in order to solve the above problem, the display control method for a mobile terminal device according to the present invention stores display means for displaying at least one of an image and video as content, with at least the content display surface exposed, A display control method for a portable terminal device, comprising: a housing that is rotatably supported with respect to a device main body; and a rotation mechanism that maintains the housing in a rotation state at at least two different angles. The rotation state of the casing maintained by the control unit is detected, the content displayed on the display means is rotated according to the detection result of the rotation state of the casing, and the rotated content is converted into a video signal. It is characterized by being converted to, and output to an external device.

  According to the above configuration, the display means for displaying as content is stored with at least the content display surface exposed, and the rotation state of the casing supported rotatably with respect to the apparatus main body is detected, and the detection result is Accordingly, the content displayed on the display unit is rotated by the content rotation processing unit, and the rotated content is converted into a video signal and output to an external device by the video signal output unit. The external device displays the content that has been rotated according to the rotation of the housing.

  Thereby, when displaying the content to be displayed on the mobile terminal device on the display screen of the external device, the user can simply rotate the casing that stores the display unit of the mobile terminal device with respect to the apparatus main body. In addition, it is possible to control the rotation of the content displayed on the display screen of the external device.

  Therefore, when content is displayed on a display screen of an external device in a mobile terminal device having a rotation mechanism, the user can easily and intuitively control the rotation of the content displayed on the display screen of the external device. There is an effect that it is possible to do.

  In addition, the content rotation processing means is provided on the display means at the same rotation angle as the rotation angle from the reference position on the apparatus main body of the casing obtained from the rotation state of the casing detected by the rotation state detecting means. The displayed content may be rotated.

  According to the above configuration, the content rotation processing unit has the same rotation angle as the rotation angle from the reference position on the apparatus main body of the casing obtained from the rotation state of the casing detected by the rotation state detection unit. By performing the process of rotating the content displayed on the display means, the content is displayed on the display means as content rotated by the same rotation angle as the rotation angle of the casing according to the rotation state of the casing. The Further, the content is converted into a video signal as a content rotated by the same rotation angle as the rotation angle of the casing according to the rotation state of the casing, and the video signal is output to an external device. Therefore, the content displayed on the display screen of the external device can be erected in an intuitive and simple manner for the user.

  In the present application, “upright” means a state in which the vertical direction of the content matches the vertical direction recognized by the user, and the horizontal direction of the content matches the horizontal direction recognized by the user.

  When converting content into a video signal and outputting it to an external device, the video signal output means has a function of converting the content into a video signal, but has a function of converting the video signal into content. Do not mean. For this reason, the processing of the video signal by the video signal output unit can be performed only once every time content is input to the video signal output unit.

  In view of the above, content storage means for temporarily storing content corresponding to the video signal output to the external device by the video signal output means is provided, and the content rotation processing means is responsive to a detection result by the rotation state detection means. The content corresponding to the content displayed on the display means may be read from the content storage means, and the content may be rotated.

  In this case, the content rotation processing means reads out the content corresponding to the content displayed on the display means from the content storage means according to the detection result by the rotation state detection means, and rotates the content. The content to be rotated is stored in the content storage unit that temporarily stores the content corresponding to the video signal output to the external device by the video signal output unit.

  As a result, when the rotation state of the casing maintained by the rotation mechanism changes while the video signal is being output to the external device, the content that is the basis of the video signal currently output to the external device is again Input to the video signal output means. Then, the video signal output means performs the same processing as described above on the input content and outputs the video signal to the external device.

  Therefore, since the video signal output to the outside can be controlled each time the rotation state of the housing maintained by the rotation mechanism is changed, the content is substantially output to the external device. The video signal output to the outside can be dynamically controlled.

  The mobile terminal device according to the present invention preferably has a telephone function.

  As described above, the portable terminal device according to the present invention stores display means for displaying at least one of an image and video as content, with at least the content display surface exposed, and is supported rotatably with respect to the device body. A rotating mechanism for maintaining the casing in a rotating state at at least two different angles, a rotating state detecting means for detecting a rotating state of the casing maintained by the rotating mechanism, and the rotating state Content rotation processing means for rotating the content displayed on the display means according to the detection result by the detection means, and the content rotated by the content rotation processing means converted into a video signal and output to an external device And a video signal output means.

  Also, the method for controlling a portable terminal device according to the present invention stores display means for displaying at least one of an image and a video as content, with at least the content display surface exposed, and rotatably supports the device main body. A display control method for a portable terminal device, comprising: a housing that is arranged and a rotation mechanism that maintains the housing in a rotation state at at least two different angles, the rotation of the housing being maintained by the rotation mechanism Detecting the state, rotating the content displayed on the display means according to the detection result of the rotation state of the housing, converting the rotated content into a video signal and outputting it to an external device Is the method.

  Therefore, when content is displayed on a display screen of an external device in a mobile terminal device having a rotation mechanism, the user can easily and intuitively control the rotation of the content displayed on the display screen of the external device. There is an effect that it is possible to do.

[Embodiment 1]
A portable terminal device according to an embodiment of the present invention will be described with reference to FIGS.

  First, the configuration of the mobile terminal device according to the present invention will be described with reference to FIG.

  FIG. 2 is a diagram illustrating an appearance of the mobile terminal device according to the present invention, and is a diagram illustrating the mobile terminal device according to the present invention from the back side. 2A shows the portable terminal device according to the present invention before the rotation of the casing described later is performed, and FIG. 2B shows the case after the rotation of the casing is performed. 1 shows a portable terminal device according to the present invention.

  A mobile terminal (mobile terminal device) 100 shown in FIG. 2 has a shape including a display unit (display means) 2 and a rotation mechanism 3 in a housing 1. Note that examples of the mobile terminal device having such a shape include mobile phones mainly having a telephone function, but are not limited thereto. Incidentally, in the present embodiment, the description will be made assuming that the mobile terminal 100 is a mobile phone.

  The housing 1 includes an upper housing (a housing that is rotatably supported with respect to the apparatus main body) 1 a and a lower housing 1 b for storing the display unit 2, and housings of various members provided in the mobile terminal 100. As a role. The upper housing 1a and the lower housing 1b are rotatably connected by a hinge portion (not shown).

  The display unit 2 is stored in the upper housing 1a and includes a display device that displays content and a drive circuit for the display device.

  In the present application, content is a general term for images and videos. Examples of the content include still images or moving images recorded in a content memory 5 described later, received television broadcast images, and the like. In the present application, data obtained by converting content into data is referred to as content data.

  The display method of the display device that is the display unit 2 is not particularly limited, and various known display devices such as a liquid crystal display device, a plasma display, a CRT (Cathode Ray Tube), and an organic EL display device can be used. .

  The display unit 2 can display the vertically long content in the same state as the original content, and can display the horizontally long content while being laid down. In addition, when displaying the laid-down content on the display unit 2, the content is displayed on the entire screen of the display unit 2.

  In the present application, “side-down” means a process of rotating content by 90 degrees in a direction parallel to the display surface (content display surface) of the display unit 2. Further, in the present application, “initial content” means content that is not laid down.

  The rotation mechanism 3 can rotate and maintain only the upper housing 1a by a predetermined angle (for example, 90 degrees) in a direction parallel to the display surface of the display unit 2. That is, the rotation mechanism 3 maintains the upper housing 1a in a rotation state at at least two different angles (that is, 0 degrees and 90 degrees).

  Here, the rotation of the upper housing 1a by the function of the rotation mechanism 3 will be described in a little more detail.

  In the portable terminal 100 shown in FIG. 2A, the casing 1 portion excluding the upper casing 1a and the upper casing 1a is vertically long. In this case, the display unit 2 is vertically long like the upper housing 1a.

  Here, in the state of the portable terminal 100 shown in FIG. 2A, when only the upper casing 1a is rotated 90 degrees by the function of the rotation mechanism 3, the casing 1 portion excluding the upper casing 1a remains vertically long. Thus, only the upper housing 1a is horizontally long. That is, the mobile terminal 100 is in the state shown in FIG. Accordingly, the display unit 2 provided in the upper housing 1a is similarly rotated by 90 degrees, so that the display unit 2 changes from a vertically long shape to a substantially horizontally long shape.

  In the present application, the process of rotating only the upper housing 1a by 90 degrees by the function of the rotation mechanism 3 is referred to as “rotation of the housing”. In the present application, the case where the portable terminal 100 is not rotated and the display unit 2 is vertically long is referred to as “normal position”, and the state where the case is rotated in the normal position is referred to as “rotational position”. Called.

  FIG. 1 is a block diagram showing an internal configuration of a mobile terminal device according to the present invention.

  As shown in FIG. 1, a mobile terminal 100 which is a mobile terminal device according to the present invention includes a rotation sensor (rotation state detection means) provided in the rotation mechanism 3 in addition to the casing 1, the display unit 2, and the rotation mechanism 3 described above. 4) a content memory 5, a control unit 6, a video memory 7, a video signal output device (video signal output means) 8, a connector 9, an operation unit 10, and a wireless communication device 11.

  A display unit 2, a rotation mechanism 3 including a rotation sensor 4, a content memory 5, a control unit 6 (ie, a CPU (central processing unit)), a video memory 7, a video signal output device 8, a connector 9, an operation unit 10, and All of the wireless communication devices 11 are stored in the housing 1.

  The rotation sensor 4 is provided in the rotation mechanism 3 and detects whether the mobile terminal 100 is in the normal position or the rotation position.

  In addition, although the following method is mentioned as a method of detecting the state of the portable terminal 100 by the said rotation sensor 4, for example, It is not limited to these.

  That is, as the detection method, there is a method of detecting a rotation angle and a rotation direction by installing a rotary encoder on a rotation axis of rotation of the casing. In addition, as a detection method, a reed switch and a magnet are installed in the display unit 2 and the rotation mechanism 3, and only when the mobile terminal 100 is in a normal position (or a rotation position), a lead is generated by a magnetic force generated from the magnet. There is a method of turning on the switch. Further, as the detection method, a magnetic sensor and a magnet are installed in the display unit 2 and the rotation mechanism 3, and only when the mobile terminal 100 is in the normal position (or rotation position), the magnetic force generated from the magnet A method of operating a magnetic sensor is mentioned.

  When the rotation sensor 4 detects that the mobile terminal 100 is in the rotation position, the rotation sensor 4 notifies the rotation state detection unit 61 described later. The transmission is performed at all timings when the mobile terminal 100 is in the rotational position. That is, whenever the mobile terminal 100 is in the rotational position, the rotation sensor 4 performs the transmission.

  The rotation sensor 4 may be provided in the control unit 6.

  The content memory 5 is a recording medium for recording content data. The content memory 5 may be detachable from the portable terminal 100 or not. Examples of this type of content memory 5 include a recording device built in the mobile terminal 100, an SD (Secure Digital) memory card attached to the mobile terminal 100 from the outside, and the like, but are not limited thereto. .

  The control unit 6 includes, for example, a CPU, and includes a rotation state detection unit (rotation state detection unit) 61 and a content rotation processing unit (content rotation processing unit) 62. Details of the rotation state detection unit 61 and the content rotation processing unit 62 will be described later.

  The video memory 7 is configured by, for example, a DRAM (Dynamic Random Access Memory) and has a function as a content drawing target memory. That is, for example, content data from the content memory 5 is recorded in the video memory 7 for each pixel. As a result, the content is rendered in the video memory 7 by software.

  The video signal output device 8 converts the input content data into a video signal, and outputs it to the outside of the portable terminal 100 through the video cable 12 (see FIG. 3) connected to the connector 9.

  In addition, as a method for converting the content data input by the video signal output device 8 into a video signal, for example, the following methods may be mentioned, but the method is not limited thereto.

  That is, as the conversion method, a video signal processor (an integrated circuit that sequentially scans the content data drawn in the video memory 7 for each pixel, converts the scanned content data into a video signal, and outputs the video signal) is used. A method for performing the above conversion may be mentioned.

  The operation unit 10 mainly includes a plurality of operation button groups, and is an input device for the mobile terminal 100 used by the user to execute various operations on the mobile terminal 100. The control unit controls various operations (user operations) by the user. 6 is transmitted. The wireless communication device 11 includes a wireless circuit (not shown), a receiver (not shown), a transmitter (not shown), and the like, and is controlled by the control unit 6 based on a user operation input by the operation unit 10. Operates as a wireless phone.

  The wireless communication device 11 may be configured to include a television broadcast receiving device (not shown) that receives a television broadcast (digital broadcast represented by analog broadcast and / or one-segment broadcast).

  Here, the rotation state detection unit 61 and the content rotation processing unit 62 will be described.

  The rotation state detection unit 61 generates a control signal for controlling the content rotation processing unit 62 based on the detection result of the state of the mobile terminal 100 (whether the mobile terminal 100 is in the normal position or the rotation position) by the rotation sensor 4. It is sent to the content rotation processing unit 62.

  Specifically, when the rotation sensor 4 detects that the mobile terminal 100 is in the rotation position, the rotation state detection unit 61 sends a control signal for controlling the content rotation processing unit 62 to the content rotation processing unit 62.

  The content rotation processing unit 62 receives content data recorded in the video memory 7 and changes the display state of the content displayed on the display unit 2 in accordance with the control signal (that is, on the display unit 2). The content data is processed in order to rotate the displayed content. In addition, the content rotation processing unit 62 causes the video signal output device 8 to convert content data representing content whose display state has changed into a video signal.

  Specifically, the content rotation processing unit 62 receives the control signal when the mobile terminal 100 is in the rotation position. Accordingly, the content rotation processing unit 62 causes the content displayed on the display unit 2 to be displayed on its side. Further, in this case, the content rotation processing unit 62 causes the video signal output device 8 to convert the content data recorded in the video memory 7 into a video signal indicating content that satisfies the erection in the laid-down content.

  The content rotation processing unit 62 does not receive the control signal when the mobile terminal 100 is in the normal position. Accordingly, in this case, the content rotation processing unit 62 displays the content displayed on the display unit 2 as the initial content. Further, in this case, the content rotation processing unit 62 causes the video signal output device 8 to convert the content data recorded in the video memory 7 into a video signal indicating a content satisfying the uprightness in the initial content.

  In the present application, “upright in the original content” means that the vertical direction of the original content matches the vertical direction recognized by the user, and the horizontal direction of the initial content and the right and left recognized by the user. This means that the direction matches. In addition, in the present application, “upright in the content that is laid down” means that the vertical direction of the content that has been laid down coincides with the vertical direction that the user recognizes, and that the horizontal direction of the content that has been laid down and the right and left that the user recognizes This means that the direction matches.

  In addition, when the mobile terminal 100 is in the rotation position, the content rotation processing unit 62 satisfies the erection in the content in which the content data recorded in the video memory 7 is laid down with respect to the video signal output device 8. Examples of the method for converting into a video signal indicating content include the following methods, but are not limited thereto.

  That is, as the conversion method, the order in which pixels are scanned by the video signal conversion processor is changed (that is, in the specific content, the location indicated by the specific pixel in the content data drawn in the video memory 7) And the correspondence relationship between the video signal and the location indicated by the pixel are changed).

  Subsequently, the operation of the mobile terminal according to the present invention will be described with reference to FIGS.

FIG. 3 is a diagram illustrating how content is displayed on the display unit 2 of the mobile terminal 100 and the display screen 14 of the external device 13. In FIG. 3A, since the mobile terminal 100 is in the normal position and the content is vertically long, it is displayed on the display unit 2 of the mobile terminal 100 as the initial content. In FIG. 3 ( c ), the mobile terminal 100 is in the normal position and the content is horizontally long so that it is laid down and displayed on the display unit 2 of the mobile terminal 100. In FIG. 3 ( b ), the mobile terminal 100 is in the rotational position, and the content is horizontally long so that it is laid down and displayed on the display unit 2 of the mobile terminal 100.

  In FIG. 3, the mobile terminal 100 is connected to the external device 13 by the video cable 12. The external device 13 has a display screen 14. In this case, the mobile terminal 100 can convert the content data into a video signal and output it to the external device 13. When the video signal is input to the external device 13, the external device 13 generates content data based on the input video signal and displays the content data on the display screen 14. The external device 13 may be a television receiver or the like, but is not limited to this.

  In the case of FIG. 3A, the mobile terminal 100 is in the normal position. In this case, the content data is converted into a video signal indicating content that satisfies the erecting of the content at the time of initial acquisition, and is output to the external device 13. Moreover, since the content displayed on the display unit 2 of the mobile terminal 100 is vertically long, the content is displayed on the display unit 2 of the mobile terminal 100 as the initial content. Therefore, the content displayed on the display screen 14 of the external device 13 is displayed on the display screen 14 of the external device 13 because the content at the time of initial acquisition is displayed in a state that satisfies the erecting in the content at the time of initial acquisition. The content is upright.

In the case of FIG. 3C as well, as in the case of FIG. 3A, since the mobile terminal 100 is in the normal position, the content data is converted into a video signal indicating the content that satisfies the erecting in the initial content. It is converted and output to the external device 13. However, since the content displayed on the display unit 2 of the mobile terminal 100 is horizontally long, the content is displayed on the display unit 2 of the mobile terminal 100 as content that has been laid down. For this reason, the content displayed on the display screen 14 of the external device 13 is displayed on the display screen 14 of the external device 13 because the laid-down content is displayed in a state where the upright content in the original content is satisfied. Content is not upright.

If Figure 3 (b), the mobile terminal 100 is a rotary position. In this case, the content data is converted into a video signal indicating content satisfying the uprightness in the laid-down content, and is output to the external device 13. And since the content displayed on the display part 2 of the portable terminal 100 is horizontally long, it is displayed on the display part 2 of the portable terminal 100 as a laid-down content. Therefore, the content displayed on the display screen 14 of the external device 13 is displayed on the display screen 14 of the external device 13 because the content that has been laid down is displayed in a state in which the upright content in the laid-down content is satisfied. The content is upright.

  Thereby, the mobile terminal 100 changes the vertical direction and the horizontal direction of the content displayed on the display screen 14 of the external device 13 according to its own state (whether the mobile terminal 100 is in the normal position or the rotation position). Can be made.

  FIG. 4 shows changes in the vertical and horizontal directions of content displayed on the display screen 14 of the external device 13 according to the state of the mobile terminal 100 (whether the mobile terminal 100 is in the normal position or the rotational position). It is a flowchart which shows the flow of the process to perform. In the flowchart shown in FIG. 4, the acquisition of content data by the video signal output device 8 is usually performed between START and step S1 (that is, content recorded in the video memory 7 by the video signal output device 8). After the data is acquired, the rotation state detection unit 61 detects the state of the mobile terminal 100), but is not limited to this.

  First, the rotation state detection unit 61 detects the state of the mobile terminal 100 (whether the mobile terminal 100 is in the normal position or the rotation position) (S1).

  When the detection result in step S1 is the normal position, the rotation state detection unit 61 does not output the control signal. At this time, the content rotation processing unit 62 causes the video signal output device 8 to convert the content data recorded in the video memory 7 into a video signal indicating content satisfying the uprightness in the original content ( S2).

  On the other hand, when the result of the detection in step S <b> 1 is the rotation position, the rotation state detection unit 61 outputs the control signal to the content rotation processing unit 62. At this time, the content rotation processing unit 62 causes the video signal output device 8 to convert the content data recorded in the video memory 7 into a video signal indicating content satisfying the uprightness in the laid-down content ( S3).

  From the above, the mobile terminal according to the present invention can erect the original content in the normal position. In addition, the portable terminal according to the present invention can erect content that has been laid down in the rotational position. That is, in the portable terminal according to the present invention, the content displayed on the display screen of the external device can be erected only by rotating the casing. Therefore, the content displayed on the display screen of the external device can be erected in an intuitive and simple manner for the user.

[Embodiment 2]
A portable terminal device according to an embodiment of the present invention will be described with reference to FIG.

  FIG. 5 is a block diagram showing an internal configuration of a mobile terminal device according to another embodiment of the present invention.

  A mobile terminal (mobile terminal device) 101 illustrated in FIG. 5 includes a memory (content storage unit) 15 in addition to the configuration of the mobile terminal 100 illustrated in FIG. 1, and includes a video memory storage processing unit 63 in the control unit 6.

  When content data is recorded in the video memory 7, the video memory storage processing unit 63 reads the content data from the video memory 7 and records it in the memory 15. When predetermined content data is stored in the memory 15 during recording processing in the memory 15, the video memory storage processing unit 63 discards the content data stored in the memory 15 and then stores the content data in the memory 15. It is preferable to start the recording process.

  An example of the memory used as the memory 15 is a DRAM. In this embodiment, the memory 15 and the video memory 7 are provided as separate memories. However, the present invention is not limited to this. That is, the memory 15 and the video memory 7 may be provided as the same recording medium.

  The control signal sent from the rotation state detection unit 61 when the mobile terminal 101 is in the rotation position is input to the content rotation processing unit 62.

  When the input of the control signal to the content rotation processing unit 62 is started or stopped, the content rotation processing unit 62 reads the content data recorded in the memory 15 and displays the content displayed on the display unit 2 according to the control signal. The content data is processed in order to change the display state. In addition, the content rotation processing unit 62 causes the video signal output device 8 to convert content data representing content whose display state has changed into a video signal.

  That is, the content rotation processing unit 62 reads the content data recorded in the memory 15 every time the state of the mobile terminal 100 (whether the mobile terminal 101 is in the normal position or the rotational position) changes. And the content rotation process part 62 performs the process similar to embodiment mentioned above with respect to the said content data.

  Note that the mobile terminal 101 shown in FIG. 5 is connected to the external device 13 in the same manner as the above-described embodiment, that is, by the connection method shown in FIG. That is, the mobile terminal 101 shown in FIG. 5 is connected to the external device 13 by the video cable 12. The external device 13 has a display screen 14. In this case, the mobile terminal 100 can display the content on the display screen 14 of the external device 13 by converting the content data into a video signal and outputting the video signal to the external device 13. Examples of the external device 13 include a television receiver and the like, but are not limited thereto.

  When the content data is converted into a video signal and output to the external device 13, the video signal output device 8 has a function of converting the content data into a video signal, but a function of converting the video signal into content data. Does not have. For this reason, the video signal output by the video signal output device 8 according to the above-described embodiment can be performed only once every time content data is input to the video signal output device 8.

  For this reason, while content data is not input to the video signal output device 8, even if the casing is rotated, the vertical and horizontal directions of the content displayed on the display screen 14 of the external device 13 do not change.

  Therefore, mobile terminal 101 according to the present embodiment inputs content data recorded in memory 15 to content rotation processing unit 62 every time the housing is rotated. And the content rotation process part 62 can perform the process similar to embodiment mentioned above with respect to the input content data.

  In the memory 15, the content data input to the video signal output device 8 last time is displayed on the display screen 14 of the external device 13 lastly (currently displayed on the display screen 14 of the external device 13). Content data that is the basis of the content is recorded.

  Therefore, the mobile terminal 101 according to the present embodiment is currently displayed on the display screen 14 of the external device 13 when the casing is rotated while the content is displayed on the display screen 14 of the external device 13. The content data that is the basis of the current content is input to the video signal output device 8 again. Then, the video signal output apparatus 8 can display the content on the display screen 14 of the external device 13 by performing the same processing as the above-described embodiment on the input content data.

  Thereby, in a state where the content is displayed on the display screen 14 of the external device 13, the content displayed on the display screen 14 of the external device 13 can be erect every time the casing is rotated. That is, the video signal output to the outside can be controlled each time the own state (whether the mobile terminal 101 is in the normal position or the rotation position) is changed. Therefore, the video signal to be output to the outside can be dynamically controlled while the content is being output to the external device 13.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and the embodiments can be obtained by appropriately combining technical means disclosed in different embodiments. The form is also included in the technical scope of the present invention.

  The mobile terminal device of the present invention can be suitably used for a mobile phone or the like as a mobile terminal device that has, for example, a rotation mechanism, converts content data into a video signal, and outputs the video signal to an external device.
