  FIG. 1 is an external view of a first embodiment of a mobile phone according to the present invention. FIG. 1A is a side view showing a state where the operator is operating the mobile phone in the first videophone mode, and FIG. 1B is a side view showing a state where the mobile phone is folded when not in use. In the drawings, the same parts are denoted by the same reference numerals.

  FIG. 1A illustrates a state in which the telephone body 2 and the flip 3 that are connected to each other by the connecting portion 1 so as to be foldable are opened at a maximum angle. In the state of FIG. 1A, the operator 4 can operate the mobile phone operation unit 6 such as a numeric keypad while looking at the display unit 5. Further, in the state of FIG. 1A, it is possible to make a videophone call while looking at the face of the other party displayed on the display unit 5 while photographing the face of the operator 4 with the inner camera 7. In addition to the image captured by the inner camera 7, the display unit 5 can also display an image captured by the outer camera 10 described later, and an image transmitted from the other party through communication in the videophone mode. .

  In the first videophone mode, the voice of the operator 4 is collected by the voice input unit 8 such as a microphone provided in the telephone body 2, and the other party from the voice output unit 9 such as a speaker provided in the flip 3. Can hear the voice of In the first videophone mode, switching is performed so that the sensitivity of the voice input unit 8 is higher and the volume of the voice output unit 9 is higher than in the normal telephone mode described later.

  Due to the switching described above, the voice input unit 8 includes a first voice input device (not shown) for collecting voice emitted from the vicinity of the voice input unit 8 and a position away from the voice input unit 8. There is provided a second voice input device (not shown) for collecting voice emitted from the voice. The audio output unit 9 includes a first audio output device (not shown) for listening to audio by positioning the audio output unit 9 in the vicinity of the ear, and the audio output unit 9 at a location away from the ear. A second sound output device (not shown) is provided for listening to the sound by positioning.

  Instead of the configuration as described above, a common voice input device and voice output device are used for the voice input unit 8 and the voice output unit 9, respectively, and the input signal and the output signal are electrically switched. In particular, the first and second audio input devices and the first and second audio output devices may be respectively configured.

In the first videophone mode, if the inner camera 7 is switched to the outer camera 10, the outside world viewed by the operator 4 can be photographed instead of his / her face and transmitted to the other party. The outer camera 10 is provided for use in main camera shooting, and is disposed in the vicinity of the connection portion 1 and has a more enhanced optical performance than the inner camera 7. Further, the direction of the optical axis 10a is variable. The direction of the optical axis 10a is switched by rotating the outer camera 10 about the short direction of the telephone body 2 as a rotation axis, and the angle formed by the audio input unit 8 and the audio output unit 9 with the connection unit 1 interposed therebetween. Automatically controlled according to the For example, as in the state of FIG. 1A, when the mobile phone is naturally tilted away from the ear, the angle of the outer camera 10 is controlled so that the optical axis 10a is horizontal. As a result, the angle theta ₁₀ formed by the optical axis 10a and the plane of the portable telephone operation section 6 of the outer camera 10 becomes an obtuse angle. In this state, the optical axis 10 a of the outer camera 10 is not parallel to the normal line of the display unit 5. Note that the vertical direction of the images taken by the inner camera 7 and the outer camera 10 coincides with the vertical direction when the mobile phone is held. Therefore, the image information captured by the outer camera 10 in this state is handled in the vertical direction during subsequent display, transfer, and recording. In the operation state of FIG. 1A, it is assumed that the operator holds the mobile phone with one hand while holding the phone body 2 as indicated by an arrow.

  In the mobile phone in FIG. 1A, in addition to the display unit 5, a look-in type display unit 11 is provided in the vicinity of the voice input unit 8. In the view-type display unit 11, as with the display unit 5, it is possible to display an image taken by the outer camera 10 and an image transmitted from the other party through communication in the videophone mode. This peep-type display unit 11 is in a position where the operator 4 cannot easily peek when the mobile phone is held in the state of FIG. 1A, and its use is not assumed. The function of the view-type display unit 11 will be described later.

  FIG. 1B shows a state in which the mobile phone is folded when not in use, and the mobile phone has such a non-use position and a first videophone mode position shown in FIG. It is foldable so that the relative positional relationship between the telephone main body 2 and the flip 3 changes between three positions with a second videophone mode position, which will be described later, using the view-type display unit 11. Note that the angle of the outer camera 10 at the non-use position in FIG. 1B is different from the angle at the first videophone mode position shown in FIG. 1A and is the same as the second videophone mode position. It is at an angle. As will be described later, the angle formed by the audio input unit 8 and the audio output unit 9 across the connection unit 1 is in the order of the unused position, the second videophone mode position, and the first videophone mode position. Accordingly, in order to avoid frequent changes in the angle of the outer camera 10, the angle of the outer camera 10 is fixed between the unused position and the second videophone mode position. Is.

  Instead of the above configuration, the angle of the outer camera 10 is changed between the unused position and the second videophone mode position, and the outer camera 10 at the unused position in FIG. It is also possible to make the optical axis 10a perpendicular to the surface of the telephone body 2 and to make the lens surface of the outer camera 10 flat with respect to the back surface of the telephone body 2 when not in use. .

  In any of the above cases, at the first videophone mode position or the second videophone mode position, the outer camera 10 does not have the optical axis 10a perpendicular to the back surface of the telephone body 2, and The angle is inclined with respect to the normal direction of the back surface.

  FIG. 2 shows the cellular phone of the first embodiment in the normal telephone mode together with the operator. FIG. 2 (a) is a front view thereof, and FIG. 2 (b) is a top view thereof. In each figure, the same parts as those in FIG.

  In the normal telephone mode in FIG. 2, the telephone main body 2 and the flip 3 which are connected to each other by the connecting portion 1 so as to be foldable are opened at the maximum angle, and the angle of the outer camera 10 is also shown in FIG. Same as 1 (a). In the normal telephone mode shown in FIG. 2A, as indicated by the arrow, the operator 4 can hold the mobile phone with one hand while holding the telephone body 2 as in the operation state of FIG. Assumed.

  Further, in the normal telephone mode of FIG. 2, the use of the peep-type display unit 11 is not assumed. As can be seen from FIG. 2A, the peep-type display unit 11 is not in front of the operator 4 when holding the mobile phone in the normal telephone mode. Further, as can be seen from FIG. 2 (b), in the normal telephone mode, even if the way of holding the mobile phone is changed and the view-type display unit 11 is brought near the eyes, the visual axis of the operator 4 Since A and the optical axis 11a of the peep-type display unit 11 do not coincide with each other, the peep-type display unit 11 cannot be easily peeped from the operator 4.

  FIG. 3 shows the cellular phone of the first embodiment used in the second videophone mode position together with the operator. FIG. 3 (a) is a front view thereof, and FIG. It is the top view. In each figure, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals.

  In the second videophone mode position in FIG. 3, the opening angle of the telephone body 2 and the flip 3 that are foldably connected to each other by the connecting portion 1 is narrower than in the state of FIG. 2. Hereinafter, this angle is referred to as “center opening angle”. Note that the connection unit 1 employs a mechanism for giving the operator 4 a click feeling for facilitating the setting of the center opening angle. As indicated by the arrows, it is assumed that the operator 4 holds the mobile phone with one hand holding the flip 3 at the second videophone mode position in FIG.

  As can be seen from FIG. 3A, in the mobile phone in the second videophone mode position, the telephone body 2 is lifted in front of the face, and the peep-type display unit 11 is looked into in a natural lower eye state. It is possible. As can be seen from FIG. 3 (b), the positional relationship between the peep-type display unit 11 and the eyes of the operator 4 at the second videophone mode position is as follows. The axis A is in a positional relationship that easily matches.

The angle of the outer camera 10 differs from the FIG. 2 (b), the in FIG. 3 (b), the angle theta ₁₀ formed between the optical axis 10a and the plane of the mobile telephone operating part 6 is an acute angle, the optical axis 10a is The angle is set to be substantially parallel to the optical axis 11 a of the viewing type display unit 11. For this reason, the direction of the screen shot by the outer camera 10, the direction seen by the eyes of the operator 4, and the viewing direction of the viewing type display unit 11 are all substantially the same. Therefore, when an image photographed by the outer camera 10 is displayed on the peep-type display unit 11, the center of the image and the center of the field of view seen by the eyes of the operator 4 substantially coincide.

  The angle of the outer camera 10 is configured to be finely adjusted according to the focus adjustment position of the outer camera 10. For example, when focusing on a long distance, the optical axis 10 a is the eye of the operator 4. Although it is set to be parallel to the visual axis A, when focusing on a short distance, the optical axis 10a is set to be inclined toward the visual axis A of the operator 4's eyes.

  Also, the vertical direction of the screen shot by the outer camera 10 at the second videophone mode position in FIG. 3B is when the mobile phone is held vertically at the first videophone mode position in FIG. The upper and lower directions of the screen shot by the outer camera 10 are different. Specifically, the image information is approximately 90 degrees different, and the image information captured by the outer camera 10 in the second videophone mode is handled in the vertical direction during subsequent display, transfer, and recording.

  The outer camera 10 has a focus adjustment mechanism (not shown). In the first videophone mode position of FIG. 1A, the focus adjustment position of the outer camera 10 is an area centered on a long distance. In contrast to the automatic setting, in the second videophone mode of FIG. 3B, the focus adjustment position of the outer camera 10 is automatically set to be an area centered on a short distance. This assumes that in the second videophone mode position, an object scene such as a document or a sample, which is in the vicinity of the operator 4, is often photographed. Of course, even in the second videophone mode position of FIG. 3 (b), since the far side may be photographed by the outer camera 10, if necessary, it is manually adjusted so that the focus adjustment position is an area centered on the far distance. It is possible to switch the focal position by adjustment or autofocus means.

  FIG. 4 is a front view of the mobile phone of the first embodiment at the second videophone mode position. In FIG. 4, the mobile phone operation unit 6 is illustrated as being divided into a numeric keypad 6a and a direction instruction key 6b. However, the same parts as those in FIGS. Will not be described.

  The numeric keypad 6a is an input interface for inputting a telephone number of a call destination, and the direction instruction key 6b is an input interface for menu selection, release operation of the outer camera 10 and the inner camera 7, zoom operation, and the like. It is.

  In this embodiment, the display unit 5 is not used in the second videophone mode position and is not displayed. However, in order to explain the function of the view-type display unit 11, the display is not performed in FIG. The screen is displayed with a broken line. When the vertical direction of the screen displayed on the display unit 5 is compared with the vertical direction of the image 12 seen when looking into the sight-type display unit 11, they are not parallel to each other and are almost 90 degrees different from each other. In addition, the vertical direction of the image 12 that can be seen when looking into the viewing type display unit 11 is longer than the lateral direction. This corresponds to the fact that the vertical direction of the screen displayed by the display unit 5 is also longer than the horizontal direction. For this reason, the aspect ratio of the screen is the same both when the display unit 5 is used and when the view type display unit 11 is used.

  As already described, at the second videophone mode position, it is assumed that the operator 4 holds the mobile phone with one hand holding the flip 3. In the second videophone mode position, when the operator 4 takes the flip 3 with the right hand and looks into the peeping display unit 11 with the right eye, the operator 4 takes the flip 3 with the left hand and peeks with the left eye. It is assumed that the user is looking into the display unit 11. For this reason, the mobile phone of the first embodiment is provided with a right-hand operation unit and a left-hand operation unit symmetrically on both sides of the flip 3 as a video phone function operation unit in the second video phone mode position. .

  Specifically, as the right-hand operation unit, the right-hand image for switching the display of the peeping display unit 11 between an image sent from the other party and an image taken by the outer camera 10 is displayed. A switching button 13, a right-hand release button 14 for performing shutter release, and a right-hand instruction destination switching for switching between performing these operations on one's own mobile phone or the other's mobile phone. A button 15 is provided. On the other hand, a left-hand image switching button 16, a left-hand release button 17, and a left-hand instruction destination switching button 18 are provided as positions on the left-hand operation unit with the display unit 5 interposed therebetween. When one of the right-hand operation unit and the left-hand operation unit is enabled, the other is disabled, and the switching is automatically performed by the gravity detection unit.

  The zoom operation dial 19 for the outer camera is configured to be rotatable about a direction perpendicular to the display unit 5 as a rotation axis, and the end of the flip 3 can be rotated with the thumb in either the right hand operation or the left hand operation. Provided in the department. However, switching processing is internally performed in a circuit so that the direction of the rotation operation toward the tele side is reversed between the case where the operation is performed with the right hand and the case where the operation is performed with the left hand. This switching is also automatically performed by the gravity detector.

  The right-hand function button 19R and the left-hand function button 19L are for switching the function of the zoom operation dial 19, and the left-right switching is the same as the relationship between the right-hand image switching button 13, the left-hand image switching button 16, and the like. . When the zoom operation dial 19 is operated while pressing the right-hand function button 19R or the left-hand function button 19L, the function of the zoom operation dial 19 is switched to the on-screen cursor operation. When operated while pressing the right-hand function button 19R or the left-hand function button 19L, the zoom operation dial 19 is slidable not only in the rotation direction but also in the pushing direction into the flip 3, and further in a direction orthogonal to the rotation direction. Can also be tilted. When the right-hand function button 19R or the left-hand function button 19L is pressed, a cursor mark appears on the screen of the peep-type display unit 11.

  When the zoom operation dial 19 is rotated or the zoom operation dial 19 is tilted in a direction orthogonal to the rotation direction in a state where the cursor is switched for the on-screen cursor operation, the screen is displayed on the screen of the peep-type display unit 11. The cursor mark to be moved moves up / down / left / right. The direction of movement of the cursor mark in the vertical and horizontal directions is reversed depending on whether the right hand function button 19R is pressed or the left hand function button 19L is pressed. In addition, when the zoom operation dial 19 is operated to be pushed into the flip 3 while the cursor is over the menu or button displayed on the screen of the view-type display unit 11, the menu or button is clicked. It becomes operation.

  The above cursor movement also appears on the screen of the other party who is talking in the second videophone mode. Therefore, it is possible to visually designate a desired portion for a partner communicating with a shared field of view.

  The detection information of the right hand operation and the left hand operation by the gravity detection unit is transmitted not only to the switching of the operation unit as described above but also to the display control unit of the look-in display unit 11, and the top and bottom of the displayed image is operated by the right hand operation. Switching is performed so as to be reversed between the case of and the case of left-hand operation.

  The operation unit 13 or zoom operation dial 19 provided on the flip 3 for the second videophone mode, and the right-hand function button 19R and the left-hand function button 19L are in the normal phone mode or the first videophone. It is inactive in mode.

  FIG. 5 is a side sectional view of the telephone main body 2 in the first embodiment, and shows the details of the configuration of the viewing display section 11. The same parts as those in FIGS. 1 to 4 are denoted by the same reference numerals, and the description thereof is omitted unless particularly supplemented.

  In FIG. 5, the peep-type display unit 11 includes a display element 111 including a liquid crystal display device and an eyepiece optical system 112 including an eyepiece for viewing an enlarged virtual image. As shown in FIG. 4, the view-type display unit 11 is arranged so that the longitudinal direction thereof is orthogonal to the longitudinal direction of the telephone body 2, and therefore, in FIG. I can see it. On the other hand, in FIG. 4, assuming that the peep-type display unit 11 is arranged so that the longitudinal direction thereof is parallel to the longitudinal direction of the telephone body 2, in FIG. The cross section can be seen, resulting in a need for more space in the thickness direction of the telephone body 2. As can be seen, as in the first embodiment, the peek type display unit 11 was arranged so that the longitudinal direction thereof was orthogonal to the longitudinal direction of the telephone body 2 and the peep type display unit 11 was peeked. The configuration in which the image 12 that is sometimes visible is vertically long leads to a reduction in the thickness of the telephone body 2, and is effective in arranging the view-type display unit 11 in a compact manner.

  The eyepiece optical system 112 is provided in the vicinity of the surface of the telephone body 2, and its optical axis 11a indicates the direction of the pupil of the operator 4 at the second videophone mode position, as shown in FIG. It is inclined toward the connecting portion 1 side with respect to the normal direction of the surface of the telephone body 2 so as to face. In addition, in the vicinity of the eyepiece optical system 112, the eyepiece optical system 112 is placed in the direction of the optical axis 11a so that the operator 4 can easily observe the image displayed on the peep-type display unit 11 even in nearsightedness or farsightedness. A diopter adjustment mechanism 113 that adjusts the diopter by moving the diopter is provided.

Further, the view-type display unit 11 is provided with a reflection optical system 114 such as a mirror for bending the optical axis 11a of the eyepiece optical system 112. As a result, the eyepiece optical system 112 reaches the display element 111. The optical path is bent toward the end of the telephone body 2 on the voice input unit 9 side (left side in FIG. 5). The angle theta ₁₁ to the optical axis 11a of the eyepiece optical system 112 forms a reflection optical system 114 is set to be an acute angle, it is preferably set to be _{0 ° <θ 11 <45 °} . The above configuration is also effective in arranging the view-type display unit 11 in a compact manner.

  The display element 111 is a transmissive element, and an illumination unit 115 is provided behind it. As described above, since the optical path from the eyepiece optical system 112 to the display element 111 is bent toward the end of the mobile phone, the illumination unit 115 is positioned closer to the end of the phone body 2 on the voice input unit 8 side. Therefore, the arrangement is effective in dissipating heat from the illumination unit 115 accompanied by heat generation.

  The illumination unit 115 has a brightness control unit (not shown) that controls the brightness, and the brightness control unit is based on the average value of the level of the image signal output from the outer camera 10. The power supplied to the illumination unit 115 is controlled. As a result, the display brightness of the peep-type display unit 11 changes according to the brightness of the object field captured by the outer camera 10, and the peep-type display is performed with the right eye as shown in FIG. Even when looking into the display unit 11 and looking at the object scene with the left eye, the intensity of light entering both eyes of the operator 4 is prevented from becoming unbalanced. Since the scene viewed by the left eye of the operator 4 and the scene captured by the outer camera 10 are in the same direction, such a configuration enables extremely rational brightness control.

  FIG. 6 is a functional block diagram of the first embodiment of the mobile phone according to the present invention. In FIG. 6, the right-hand function button 19 </ b> R and the left-hand function button 19 </ b> L are present in the right-hand / left-hand operation unit 28, although they are not shown for the sake of space. In addition, the same parts as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof is omitted unless particularly supplemented.

  In FIG. 6, the control unit 20 controls the entire functions of the mobile phone, and each functional block is connected. When not in use, when the mobile phone is folded as shown in FIG. 1B, the bending angle detection unit 21 detects this and sends a detection result signal to the control unit 20. In response to this, the control unit 20 controls the input / output switching unit 22 to place the input / output unit 23 in a non-operating state.

  When the mobile phone is opened at the maximum angle as shown in FIG. 1A in order to set the normal telephone mode, the bending angle detection unit 21 detects this, and the control unit 20 responds accordingly by changing the input / output switching unit. 22 is controlled to set the input / output unit 23 to the normal telephone mode. Specifically, the voice input unit 8 is set to low sensitivity, the voice output unit 9 is set to a low volume, and suitable for a call with the mobile phone positioned near the face as shown in FIG. Set to In addition, the display unit 5 is set in an operating state, and the view-type display unit 11 is set in a non-operating state. In this state, if the mobile phone operation unit 6 is operated while looking at the display unit 5 and the telephone number of the other party is input to make a call, the communication unit 24 functions and a normal call can be made.

  In the normal telephone mode, the camera switching unit 25 controls the outer camera 10 of the camera unit 26 and sets its optical axis angle to the state shown in FIG. Therefore, if the mobile phone operation unit 6 is operated to switch to the camera mode, a photograph can be taken. In the camera mode, the camera unit 26 operates. Normally, the outer camera 10 captures the scene and displays an image signal on the display screen of the input / output unit 23. Since the outer camera 10 has a zoom function, zooming can also be performed by operating the mobile phone operation unit 6. When the composition is determined by looking at the display unit 5 and the release is performed by operating the cellular phone operation unit 6, the image signal from the camera unit 26 is recorded in the recording unit 27. The image of the recording unit 27 can also be reproduced and displayed on the display unit 5 by operating the mobile phone operation unit 6.

  On the other hand, when the cellular phone operation unit 6 is operated to make a call in the first videophone mode, the input / output switching unit 22 controls the input / output unit 23 and sets the voice input unit 8 to high sensitivity. The sound output unit 9 is set to a high volume, and is set to be appropriate for making a call with the mobile phone away from the face as shown in FIG. Even in the first videophone mode, the display unit 5 is in an operating state and the view-type display unit 11 is in a non-operating state. The display unit 5 normally displays both an image taken by the outer camera 10 or the inner camera 7 and an image transmitted from a partner communicating in the first videophone mode. The displayable area of the display unit 5 is divided into a main display area for main display and a sub display area having a smaller display area than the main display area. The captured image is displayed, and an image transmitted from the communicating party is displayed in the sub display area. Note that the display state of the display unit 5 can be switched by operating the mobile phone operation unit 6. For example, only the image captured by the outer camera 10 or the inner camera 7 is displayed or communicated. It is also possible to display only images transmitted from the other party.

  Further, when a call is made in the first videophone mode, the optical axis angle 10a of the outer camera 10 is set to the state shown in FIG. The control unit 20 controls the camera unit 26 by an operation for making a call in the first videophone mode, and usually makes the inner camera 7 in an operating state so that his / her face is imaged, and the outer camera 10 is turned off. Set to operating state. However, it is possible to arbitrarily switch the operation so that the outer camera 10 is in the operating state and the inner camera 7 is in the non-operating state by operating the mobile phone operation unit 6.

  When the mobile phone is set to a middle opening angle as shown in FIG. 3 in order to make a call in the second videophone mode, the bending angle detection unit 21 detects this, and the control unit 20 inputs / outputs accordingly. The switching unit 22 is controlled to set the input / output unit 23 to the second videophone mode. Specifically, the voice input unit 8 is set to low sensitivity, the voice output unit 9 is set to a low volume, and the mobile phone is positioned near the face as shown in FIG. Set to Further, the view type display unit 11 is set in an operating state, and the display unit 5 is set in a non-operating state. In the view-type display unit 11, similarly to the display unit 5, the display state can be switched by operating the right-hand image switching button 13 or the left-hand image switching button 16.

  When making a call in the second videophone mode, the control unit 20 controls the camera unit 26 to bring the outer camera 10 into an operating state and set the optical axis angle 10a of the outer camera 10 as shown in FIG. Set to state.

  To start communication in the second videophone mode, first, in the first videophone mode, the mobile phone operation unit 6 is operated while looking at the display unit 5, and the telephone number of the other party is input to make a call. When the communication unit 24 functions and the telephone is connected, the opening angle of the mobile phone is set to the middle opening angle in order to switch to the second videophone mode.

  As described above, the switching operation to the second videophone mode is performed immediately after the start of communication as described above, and also when the telephone call is initially started in the first videophone mode and then switched to the second videophone mode. It is the same. The same applies when starting a call in the normal telephone mode and switching to the second videophone mode on the way. That is, in any case, when the line is connected, the switching to the second videophone mode is performed by changing the opening angle of the telephone body 2 and the flip 3 from the maximum angle to the middle opening angle.

  Operations during a call in the second videophone mode are performed by the right-hand / left-hand operation unit 28. The right hand / left hand operation unit 28 includes the right hand image switching button 13, the right hand release button 14, the right hand instruction destination switching button 15, the left hand image switching button 16, the left hand release button 17, and the left hand. An instruction destination switching button 18 is included. When one of the right-hand operation unit and the left-hand operation unit is enabled, the other is disabled, but this switching can be automatically performed by the gravity detection unit 29. Specifically, when the operator brings the mobile phone close to the face, the gravity detection unit 29 detects which one of the right hand operation unit and the left hand operation unit is located above, and the detection result is the control unit. 20 is sent. Thereafter, the left / right switching unit 30 is controlled by the control unit 20, and the operation unit for the right hand / left hand is operated so as to validate the operation unit on the upper side and invalidate the operation unit on the lower side. The unit 28 is set.

  Further, based on the detection result of the gravity detection unit 29, the control unit 20 internally circuitizes so that the rotation operation direction of the zoom operation dial 19 toward the tele side is reversed between the right-hand operation and the left-hand operation. Process and control the zoom mechanism of the outer camera 10. Further, the control unit 20 controls the display control unit of the peep-type display unit 11 based on the detection result of the gravity detection unit 29, so that the displayed image is reversed between the right-hand operation and the left-hand operation. The setting of the view-type display unit 11 is switched so that

  As described above, the switching to the second videophone mode is normally performed by changing the opening angle of the telephone body 2 and the flip 3 from the maximum angle to the middle opening angle. When the other party switches to the second videophone mode, the reception is switched to the second videophone mode even if the telephone body 2 and the flip 3 are opened at the maximum angle as shown in FIG. And the display of the peeping type display part 11 also starts. However, if the receiving side is not aware of this, the input / output unit 23 is provided with a warning unit 31 such as a lamp, and when this is blinking, the switching to the second videophone mode has been performed. Warning. The warning unit 31 is provided on the outer wall of the mobile phone near the voice input unit 8, and the blinking thereof enters the eyes of the operator 4 who is talking in the state of FIG. If the operator 4 notices this and sets the opening angle of the telephone body 2 and the flip 3 to the middle opening angle, the warning unit 31 stops blinking. Note that switching to the second videophone mode during normal telephone calls is performed not only by the warning unit 31 but also by emitting a warning sound from the audio output unit 9 for a short time.

  The warning unit 31 also functions when the caller makes a call with the second videophone mode set while the telephone body 2 and the flip 3 are not in the second videophone mode position. In this case, the operator 4 who has seen the warning unit 31 understands that the incoming call is in the second videophone mode, and performs reception by setting the opening angle of the telephone body 2 and the flip 3 to the middle opening angle. . At first, even if the user does not notice the flashing of the warning unit 31 and erroneously starts reception at a position other than the second videophone mode, as described above, as in the case of switching to the second videophone mode from the middle, This can be noticed because the warning section 31 blinks.

  The direction detection unit 32 detects which direction the optical axis 10a of the outer camera 10 is directed, and the result is transmitted to the control unit 20 and is also transmitted from the communication unit 24 to the other party of the call as necessary. It is done.

  FIG. 7 is a flowchart showing the function of the control unit 20 of FIG. 6, for explaining the operation when the power is turned on. When the flow starts, it is checked in step S1 whether the mobile phone is opened from a non-use state or if any of the operation units is operated to turn on the power. If the flow is on, step S2 is performed. Proceed to and start resetting the no-operation timer. It should be noted that this non-operation timer is reset again at that time when any operation is performed by the operator in a later step, and counting is started therefrom. In step S3, the audio input unit 8 is set to low sensitivity input, and the audio output unit 9 is set to low volume output so as to be compatible with the normal telephone mode or the second videophone mode.

  In step S4, it is checked whether or not the detection result of the bending angle detection unit 21 is the angle of the second videophone mode (center opening angle). If it is the angle of the second videophone mode, the process proceeds to step S5, and the view-type display unit 11 is selected as the display unit to function. That is, the peep-type display unit 11 is set in an operating state and the display unit 5 is set in a non-operating state. At this time, the illumination unit 115 of the view-type display unit 11 is set in an operating state, and the backlight of the display unit 5 is set in a non-operating state.

  Next, in step S6, the optical axis 10a of the outer camera 10 is set to the angle at the second videophone mode position, that is, the angle shown in FIG. 3B, and the focus adjustment position is centered on a short distance. Set to be the area. Further, in the state of FIG. 3A, the handling of the image data is set so that the vertical direction of the image information captured by the outer camera 10 is the vertical direction in the subsequent display, transfer, and recording.

  In step S7, the right-hand / left-hand operation unit 28, the tele-side operation rotation direction of the zoom operation dial 19 and the top-and-bottom display unit 11 are set to be right-handed. In step S8, whether the left hand is held or not is determined. To check. If it is left-handed, in step S9, all the settings in step S7 are changed to those for the left hand, and the process proceeds to step S10. On the other hand, if it is not left-handed in step S8, the setting in step S7 is left as it is and the process proceeds to step S10.

  In step S10, each operation of the mobile phone after the power is turned on can be accepted. Next, the process proceeds to step S11, where it is checked whether or not the no-operation timer has expired. If the timer has expired, the power is automatically turned off in step S12, and the process returns to step S1. On the other hand, if the no-operation timer has not timed out in step S11, the process returns to step S3, corresponding to mode change and left / right change.

  As a result of the check of the bending angle detection unit 21 in step S4, if it is not the angle at the second videophone mode position (medium opening angle), it means that the mobile phone is opened at the maximum angle. From step S13, the display unit 5 is selected as a display unit to function. That is, the display unit 5 is set in an operating state, and the peeping display unit 11 is set in a non-operating state. At this time, the backlight illumination of the display unit 5 is set in an operating state, and the lighting unit 115 of the view-type display unit 11 is set in a non-operating state.

  Further, in step S14, the optical axis 10a of the outer camera 10 is set to the angle at the first videophone position, that is, the angle shown in FIG. 1A, and the focus adjustment position is an area centered on a long distance. Set to be. Further, in the state of FIG. 1A, the handling of the image data is set so that the vertical direction of the image information captured by the outer camera 10 is the vertical direction for subsequent display, transfer, and recording.

  Next, in step S15, it is checked whether the videophone mode is set. When the mobile phone is in the video phone mode when it is opened at the maximum angle, it means that the mobile phone is in the first video phone mode, so that the process proceeds to step S16 and the voice input unit 8 is set to high sensitivity input. Then, the audio output unit 9 is changed to a high volume output, and the process proceeds to step S10. On the other hand, if the video phone mode is not set in step S15, the normal phone mode is set, and the process proceeds to step S10 without changing the input / output levels of the voice input unit 8 and the voice output unit 9.

  FIG. 8 is a flowchart showing communication processing in the video phone mode or the normal phone mode. This flow starts when the operator presses the call button and tries to talk to the other party.

  When the opening angle of his / her mobile phone is set to the middle opening angle and communication is performed with the other party in the second videophone mode, first, in step S20, the state of his / her mobile phone and the other party's mobile phone are mutually Make preparations for notification. In this step, in the subsequent steps, when the user operates the mobile phone or the other party operates the mobile phone, preparations for communicating with each other are performed. For this reason, when there is a change in the setting of the mobile phone in a later step, this is immediately transmitted to the calling party.

  Next, in step S21, it is checked whether or not the mobile phone of the user is set to the normal phone mode. Here, since the second videophone mode is set, the process proceeds to step S22 to check whether or not a warning is given by the warning unit 31. At this point, since no warning is given, the process proceeds to step S23, and it is checked whether or not the mobile phone is set to the middle opening angle.

  When communicating in the second videophone mode, since the mobile phone is set to the middle opening angle, the process proceeds to step S24, and the mobile phone is set to the second videophone mode to the other party. Notify that it is set.

  Next, in step S25, communication in the second videophone mode is started. Thereafter, the second videophone mode is continued until the user or the other party switches the operation mode of the mobile phone or the call is terminated and the line is disconnected. Communication by is continued.

  Next, in step S26, it is checked whether or not the mobile phone has been set to the middle opening angle while communication is continued. When communication is started in the second videophone mode, the process proceeds to step S26 with the intermediate opening angle set, so that the process proceeds to step S27 and the warning by the warning unit 31 is turned off. At this time, since the warning by the warning unit 31 is not made, the state where the warning is turned off is continued, and the process proceeds to step S28.

  In step S28, it is checked whether or not the call is terminated and the line is disconnected. If the line is disconnected, the communication process in the second videophone mode is terminated. On the other hand, if the line has not been disconnected, the process returns to step S21, and the processes of steps S21 to S27 are repeated as long as communication in the second videophone mode is continued. In this way, communication processing in the second videophone mode is executed.

  On the other hand, when you set the operation mode of your mobile phone to normal phone mode and communicate with the other party in normal phone mode, first, as in the case of communicating with the other party in the second videophone mode, In step S20, preparations are made for notifying each other of the state of the mobile phone of the user and the mobile phone of the other party.

  Next, in step S21, it is checked whether or not the mobile phone of the user is set to the normal phone mode. Here, since the normal telephone mode is set, the process proceeds to step S29 to notify the other party that his / her mobile phone is set to the normal telephone mode.

  Next, in step S30, communication in the normal telephone mode is started. Thereafter, communication in the normal telephone mode is continued until the user or the other party switches the operation mode of the mobile phone or the call is terminated and the line is disconnected. The

  Next, in step S31, it is checked whether or not the opening angle of the other party's mobile phone is set to the middle opening angle while communication is continued. If the opening angle of the other party's mobile phone has not been changed to the middle opening angle, the process proceeds to step S28 to check whether or not the line has been disconnected.

  On the other hand, when the opening angle of the other party's mobile phone is changed to the middle opening angle, that is, when the other party desires to switch to the telephone call in the second videophone mode, the process proceeds to step S32, The warning unit 31 of the mobile phone is operated to give a warning and notify the operator (self) that the other party wishes to make a call in the second videophone mode.

  If the warning is given, the process proceeds to step S25, and the operation mode of the own mobile phone is switched to the second videophone mode. At this time, the opening angle of his / her mobile phone is still set to an angle other than the middle opening angle. However, in step S25, the opening angle of his / her mobile phone is an angle other than the middle opening angle. Even if it exists, the operation mode of the mobile phone is forcibly switched to the second videophone mode, and communication in the second videophone mode is started.

  Next, in step S26, it is checked whether or not the opening angle of his / her mobile phone has been set to the middle opening angle. If the opening angle has been changed to the middle opening angle, the process proceeds to step S27 to stop the warning by the warning unit 31. To do.

  On the other hand, if the angle is not changed to the middle opening angle, the process proceeds to step S28 to check whether or not the line is disconnected. If the line has not been disconnected, the process returns to step S21, and in subsequent step S22, it is checked whether a warning is given by the warning unit 31. At this time, since the warning by the warning 31 is continued, it is not checked whether or not the mobile phone of step 23 is set to the middle opening angle, and the process proceeds to step S24. Thereafter, the warning by the warning unit 31 is continued until the opening angle of the mobile phone of the user is set to the middle opening angle, and communication with the call partner is performed until the line is disconnected. As described above, the communication process in the normal telephone mode is executed.

  Also, when you set your mobile phone's operation mode to the first videophone mode and communicate with the other party in the first videophone mode, you must first communicate with the other party in the second videophone mode. Similarly, in step S20, preparations for notifying each other of the state of the mobile phone of the user and the mobile phone of the other party are performed.

  Next, in step S21, it is checked whether or not the mobile phone of the user is set to the normal phone mode. Here, since it is set to the first telephone mode, through steps S22 and S23, it is sequentially determined whether or not a warning is being made and whether or not the opening angle of one's mobile phone is set to the middle opening angle. To check.

  When calling in the first videophone mode, the opening angle of one's mobile phone is set to the maximum angle, so that the process proceeds to step S33 and the first videophone is sent to the other party. It is notified that the mode is set, and communication in the first videophone mode is started in step S34.

  Next, in step S35, it is checked whether or not the opening angle of the other party's mobile phone is set to the middle opening angle while communication is continued. If the opening angle of the other party's mobile phone has not been changed to the middle opening angle, the process proceeds to step S28 to check whether or not the line has been disconnected.

  On the other hand, if the other party wishes to switch to the telephone call in the second videophone mode and the opening angle of the other party's mobile phone is changed to the middle opening angle, the process proceeds to step S36, where the warning unit of his / her mobile phone is set. The warning by 31 is performed.

  After that, until the opening angle of the other party's mobile phone is changed to the middle opening angle while talking in the normal phone mode, until the opening angle of your mobile phone is set to the middle opening angle The warning by the warning unit 31 is continued and communication with the calling party is performed until the line is disconnected.

  FIG. 9 is a flowchart showing the contents of the second videophone mode communication process in step S25 and the first videophone mode communication process in step S34 shown in FIG.

  In executing the communication processing in the videophone mode, first, in step S40, an image captured by the outer camera 10 or the inner camera 7 of the own mobile phone is transmitted to the other mobile phone, and the other mobile phone is also transmitted. Send the image you shot with and receive it on your mobile phone. As a result, both the image photographed with his / her mobile phone and the image photographed with the other party's mobile phone are displayed on the display unit 5 or the peep-type display unit 11 of his / her mobile phone.

  Next, in step S41, it is checked whether or not the user has performed an operation for changing the display screen of the display unit 5 or the peep-type display unit 11 of his / her mobile phone. For example, an operation for scrolling the display screen of the display unit 5 or the peep-type display unit 11, an operation for moving a cursor displayed in the display screen, or an enlargement of the display screen, When zoom processing for reduction is performed, this corresponds to the case where an operation for changing the display screen is performed, and the process proceeds to step S45.

  If it progresses to step S45, according to operation content, the screen process for changing the display content of the display part 5 of one's mobile telephone or the peek type display part 11 will be performed, and it will progress to step S46. Step S45 will be described in detail later with reference to FIG.

  In step S46, communication processing in the second videophone mode or the first videophone mode is executed to make a call possible state. In this way, when the call-ready state is set, the call-ready state is maintained until it is detected in step S28 in FIG. 8 that the line has been disconnected.

  On the other hand, if it is determined in step S41 that the user has not performed an operation for changing the display screen of the display unit 5 or the peek-type display unit 11 of his / her mobile phone, the process proceeds to step S42. It is checked whether or not an operation for changing the display screen of the display unit 5 or the peep-type display unit 11 of the mobile phone has been executed. If the operation has been executed, the process proceeds to step S45. If the operation has not been executed, the process proceeds to step S43.

  In step S43, it is checked whether or not the user has performed an operation for changing the display screen of the other party's mobile phone. If the operation has been performed, the process proceeds to step S45.

  On the other hand, if the operation has not been executed, the process proceeds to step S44, and it is checked whether or not the other party has performed an operation for changing the display screen of the other party's mobile phone. In the present embodiment, in step S20 in FIG. 8, since preparations for notifying the states of the mobile phone of the other party and the mobile phone of the other party are executed, the operation is not directly involved. However, information indicating the operation content is transmitted from the other party's mobile phone. Therefore, in step S44, based on the transmitted information, it can be checked whether or not the partner has performed an operation for changing the display screen of the partner's mobile phone.

  In step S44, if the partner performs an operation for changing the display screen of the partner's mobile phone, the process proceeds to step S45. If the operation is not performed, the process proceeds to step S47.

  In step S47, it is checked whether or not the user has operated the outer camera 10 or the inner camera 7 of his / her mobile phone. For example, when the release operation or zoom operation of the outer camera 10 or the inner camera 7 is executed, this corresponds to the case where the outer camera 10 or the inner camera 7 of the own mobile phone is operated, and the process proceeds to step S50.

  In step S50, a camera operation process for operating the outer camera 10 or the inner camera 7 of the mobile phone is executed according to the operation content, and the process proceeds to step S46. Step S50 will be described in detail later with reference to FIG.

  On the other hand, if the user has not operated the outer camera 10 or the inner camera 7 of his / her mobile phone, the process proceeds to step S48, and whether or not the other party has operated the outer camera 10 or the inner camera 7 of his / her mobile phone. Check. When the operation is executed, the process proceeds to step S50, and when the operation is not executed, the process proceeds to step S49.

  In step S49, it is checked whether or not the user has operated the camera of the other party's mobile phone. If the operation has been executed, the process proceeds to step S50. If the operation has not been executed, the process proceeds to step S46. move on.

  FIG. 10 is a flowchart showing the contents of the screen processing in step S45 shown in FIG.

  In executing the screen process, first, in step S61, it is checked whether an operation for changing the display screen has been executed by the user or by the other party. If the user has operated, the process proceeds to step S62. If the other party has operated, the process proceeds to step S63.

  In step S62, it is checked whether the operation target is an image displayed on the display unit 5 or the peep-type display unit 11 of the user's own mobile phone or an image displayed on the display unit of the other party's mobile phone. . When the operation target is an image displayed on the display unit 5 or the peep-type display unit 11 of the own mobile phone, the process proceeds to step S63.

  In step S 63, an image (hereinafter referred to as “outside camera 10 of his / her mobile phone” captured by the outer camera 10 or the inner camera 7 of his / her mobile phone is displayed on the display unit 5 or the view-type display unit 11 of his / her mobile phone. Alternatively, it is checked whether or not an operation for displaying “an image photographed by the inner camera 7” is sometimes referred to as “photographed image of own mobile phone”). If an operation for displaying a photographed image of his / her mobile phone is being executed, the process proceeds to step S64.

  In step S64, if the photographed image of the mobile phone is not displayed on the display unit 5 or the peek-type display unit 11 of the mobile phone, the image is displayed. On the other hand, at the time of reaching step S64, both the photographed image of the cellular phone and the transmission image from the other party are displayed on the cellular phone display unit 5 or the peep-type display unit 11. If so, maintain that state. When a transmission image from the other party is displayed in the main display area and a captured image of his / her mobile phone is displayed in the sub display area, these displays are switched in reverse.

  On the other hand, if an operation for displaying a transmission image from the other party's mobile phone is being executed in step S63, the process proceeds to step S65, where the transmission image from the other party is displayed on the display unit 5 of the own mobile phone or a peek. If it is displayed on the embedded display unit 11 and direction information is transmitted from the other party's mobile phone, the direction information is also displayed. Even in this step S65, when both the photographed image of the mobile phone and the transmission image from the other party are displayed, the state is maintained, and the captured image of the mobile phone is displayed in the main display area. Is displayed, the display mode is switched to display a transmission image from the other party.

  Next, in step S66, display screen change processing is executed in accordance with the operation content. When the change process is completed, the process proceeds to step S67, and it is checked whether or not direction information indicating the direction in which the outer camera 10 or the inner camera 7 of the mobile phone is facing can be acquired.

  If the azimuth information can be acquired, the process proceeds to step S68, and the azimuth information of the outer camera 10 or the inner camera 7 of the own mobile phone is displayed on the display unit 5 or the peep-type display unit 11 of the own mobile phone. On the other hand, if the azimuth information cannot be acquired due to the influence of geomagnetism or the like, the azimuth information display processing is not executed and the process proceeds to step S69. In step S69, it is checked whether or not the information transmitted from the mobile phone of the other party can be used. Here, “the information transmitted from the mobile phone of the other party can be used” means that, for example, when the information “scrolled” is transmitted from the mobile phone to the other mobile phone, This means that the mobile phone can correctly recognize the transmitted information as “scrolled” information. Usually, since identification information for identifying each mobile phone is given, in step S69, the identification information transmitted from the other party's mobile phone uses the information transmitted from his / her mobile phone. A check process is performed by determining whether the model can be used.

  If the other party ’s mobile phone ca n’t take advantage of the information sent from their mobile phone, it ’s not possible to correctly recognize this even if they send information that shows the changes to the display on their mobile phone. End screen processing.

  On the other hand, when the other party's mobile phone can utilize the information transmitted from his / her mobile phone, the process proceeds to step S70, and the display status of the display unit 5 or the peek-type display unit 11 of his / her mobile phone is displayed. In step S71, screen operation information indicating how the display screen is scrolled, how the cursor is moved, or whether the display screen is enlarged or reduced is transmitted. In step S72, the mobile phone orientation information is transmitted. As for the direction information in step S72, the transmission process is executed only when the direction information has been acquired in step S67.

  When the display status, screen operation details, and orientation information are transmitted to the other party's mobile phone, the other party's mobile phone is based on the transmitted display status, screen operation details, and orientation information. The display mode of the display unit is changed. Thus, when the same display content as the display unit 5 or the peep-type display unit 11 of the user's mobile phone is displayed on the display unit of the other party's mobile phone, the screen processing ends.

  On the other hand, in step S62, when the operation target is an image displayed on the display unit of the other party's mobile phone, the process proceeds to step S73, and the other party's mobile phone corresponds to his / her mobile phone. Check whether or not the operation is compatible. Here, “the other party's mobile phone corresponds to his / her mobile phone” includes that the other party's mobile phone can use information transmitted from his / her mobile phone, and by operating his / her mobile phone, It means that the other party's mobile phone can be operated.
