However, for example, a display device using EL (Electro Luminescence) may be used. In addition, a display device having an arbitrary resolution can be used as the upper LCD 22.

  The upper LCD 22 is a display device capable of displaying a stereoscopically visible image. In the present embodiment, the left-eye image and the right-eye image are displayed using substantially the same display area. Specifically, the upper LCD 22 is a display device in which a left-eye image and a right-eye image are alternately displayed in a horizontal direction in a predetermined unit (for example, one column at a time). Alternatively, the upper LCD 22 may be a display device in which the left-eye image and the right-eye image are alternately displayed in a time division manner. In the present embodiment, the upper LCD 22 is a display device capable of autostereoscopic viewing. Then, a display device of a lenticular method or a parallax barrier method (parallax barrier method) is used so that the left-eye image and the right-eye image that are alternately displayed in the horizontal direction appear to be decomposed into the left eye and the right eye, respectively. . In the present embodiment, the upper LCD 22 is a parallax barrier type. The upper LCD 22 uses the right-eye image and the left-eye image to display an image (stereoscopic image) that can be stereoscopically viewed with the naked eye. That is, the upper LCD 22 uses the parallax barrier to visually recognize the left-eye image for the user's left eye and the right-eye image for the user's right eye, thereby producing a stereoscopic image (stereoscopically viewable) having a stereoscopic effect for the user. Can be displayed. Further, the upper LCD 22 can invalidate the parallax barrier. When the parallax barrier is invalidated, the upper LCD 22 can display an image in a planar manner (in the sense opposite to the above-described stereoscopic view, the planar LCD is planar). Visual images can be displayed). As described above, the upper LCD 22 is a display device capable of switching between a stereoscopic display mode for displaying a stereoscopically viewable image and a planar display mode for displaying an image in a planar manner (displaying a planar view image). . This display mode switching is performed by a 3D adjustment switch 25 described later.

  The outer camera 23 is a stereo camera that is provided on an outer surface (back surface opposite to the main surface on which the upper LCD 22 is provided) 21D of the upper housing 21 and has a normal direction of the outer surface 21D as an imaging direction. The outer camera 23 includes two cameras, a left-eye camera 23a and a right-eye camera 23b. The left-eye camera 23a and the right-eye camera 23b are arranged so that their imaging directions are parallel to each other. The left-eye camera 23a and the right-eye camera 23b each include an imaging device (for example, a CCD image sensor or a CMOS image sensor) having a predetermined resolution and a lens.

  As shown by a broken line in FIG. 2, the left-eye camera 23 a and the right-eye camera 23 b constituting the outer camera 23 are arranged in parallel with the horizontal direction of the screen of the upper LCD 22. That is, the left-eye camera 23 a and the right-eye camera 23 b are arranged so that a straight line connecting the two cameras is parallel to the horizontal direction of the screen of the upper LCD 22. In FIG. 2, the broken lines representing the left-eye camera 23 a and the right-eye camera 23 b mean that the left-eye camera 23 a and the right-eye camera 23 b exist on the outer surface opposite to the inner surface of the upper housing 21. As shown in FIG. 2, when the user views the screen of the upper LCD 22 from the front, the left-eye camera 23a is located on the left side, and the right-eye camera 23b is located on the right side. The distance between the left-eye camera 23a and the right-eye camera 23b is set to be approximately the distance between both human eyes, and may be set, for example, in the range of 30 mm to 70 mm. The interval between the left-eye camera 23a and the right-eye camera 23b is not limited to this range. In another embodiment, the interval between the two cameras 23a and 23b may be variable.

  The left-eye camera 23a and the right-eye camera 23b are respectively arranged at positions that are symmetrical from the center with respect to the left-right direction of the upper LCD 22 (upper housing 21). That is, the left-eye camera 23a and the right-eye camera 23b are respectively arranged at positions symmetrical with respect to a line that bisects the upper LCD 22 into left and right. Further, the left-eye camera 23 a and the right-eye camera 23 b are disposed on the upper side of the upper housing 21 and on the back side above the upper end of the screen of the upper LCD 22 when the upper housing 21 is opened. That is, the left-eye camera 23a and the right-eye camera 23b are arranged on the outer surface of the upper housing 21 and above the upper end of the projected upper LCD 22 when the upper LCD 22 is projected onto the outer surface.

  As described above, the two cameras of the outer camera 23 are arranged at symmetrical positions from the center with respect to the left-right direction of the upper LCD 22, so that when the user views the upper LCD 22 from the front, the imaging direction of the outer camera 23 is set by the user. It can be matched with the line-of-sight direction. Further, since the outer camera 23 is disposed at a position on the back side above the upper end of the screen of the upper LCD 22, the outer camera 23 and the upper LCD 22 do not interfere inside the upper housing 21. Therefore, it is possible to make the upper housing 21 thinner than in the case where the outer camera 23 is disposed on the back side of the screen of the upper LCD 22.

  The inner camera 24 is a camera that is provided on the inner surface (main surface) 21B of the upper housing 21 and has the normal direction of the inner surface as the imaging direction. The inner camera 24 includes an imaging element (for example, a CCD image sensor or a CMOS image sensor) having a predetermined resolution, and a lens.

  As shown in FIG. 2, the inner camera 24 is disposed above the upper end of the screen of the upper LCD 22 in the state in which the upper housing 21 is opened, with respect to the left-right direction of the upper housing 21. Arranged at the center position. Specifically, as shown in FIG. 2, the inner camera 24 is an inner surface of the upper housing 21, and is a back side intermediate between the left and right cameras (the left-eye camera 23 a and the right-eye camera 23 b) of the outer camera 23. It is arranged at the position. That is, when the left and right cameras provided on the outer surface of the upper housing 21 are projected on the inner surface of the upper housing 21, the inner camera 24 is provided in the middle of the projected left and right cameras.

  Thus, the inner camera 24 images in the opposite direction to the outer camera 23. The inner camera 24 is provided on the inner surface of the upper housing 21 and on the back side of the intermediate position between the left and right cameras of the outer camera 23. Thus, when the user views the upper LCD 22 from the front, the inner camera 24 can capture the user's face from the front. In addition, since the left and right cameras of the outer camera 23 and the inner camera 24 do not interfere with each other inside the upper housing 21, the upper housing 21 can be made thin.

  The 3D adjustment switch 25 is a slide switch, and is a switch used to switch the display mode of the upper LCD 22 as described above. The 3D adjustment switch 25 is used to adjust the stereoscopic effect of a stereoscopically viewable image (stereoscopic image) displayed on the upper LCD 22. As shown in FIGS. 2 and 3, the 3D adjustment switch 25 is provided at the ends of the inner side surface and the right side surface of the upper housing 21, and when the user views the upper LCD 22 from the front, the 3D adjustment switch 25 is visually recognized. It is provided at a position where it can be made.

  A concave portion is formed in the right end portion of the inner surface of the upper housing 21, and the 3D adjustment switch 25 is provided in the concave portion. The 3D adjustment switch 25 is disposed so as to be visible from the front and right sides of the upper housing 21. The slider of the 3D adjustment switch 25 can be slid to an arbitrary position in a predetermined direction (vertical direction), and the display mode of the upper LCD 22 is set according to the position of the slider.

  The 3D indicator 26 indicates whether or not the upper LCD 22 is in the stereoscopic display mode. The 3D indicator 26 is an LED, and lights up when the stereoscopic display mode of the upper LCD 22 is valid. As shown in FIG. 2, the 3D indicator 26 is provided on the inner surface of the upper housing 21 and is provided near the screen of the upper LCD 22. For this reason, when the user views the screen of the upper LCD 22 from the front, the user can easily view the 3D indicator 26. Therefore, the user can easily recognize the display mode of the upper LCD 22 while viewing the screen of the upper LCD 22.

  A speaker hole 21 </ b> E is provided on the inner surface of the upper housing 21. Sound from a speaker 43 described later is output from the speaker hole 21E.

The CPU 311 of the information processing section 31 executes processing according to the program (for example, shooting processing, image display processing described later, and the like) by executing the program. Note that the program executed by the CPU 311 of the information processing unit 31 may be acquired from another device through communication with the other device. The information processing unit 31 includes a VRAM (Video RAM) 313. The GPU 312 of the information processing unit 31 generates an image in response to a command from the CPU 311 of the information processing unit 31 and draws it on the VRAM 313. Then, the GPU 312 of the information processing unit 31 outputs the image drawn in the VRAM 313 to the upper LCD 22 and / or the lower LCD 12, and the image is displayed on the upper LCD 22 and / or the lower LCD 12.

  A main memory 32, an external memory I / F 33, a data storage external memory I / F 34, and a data storage internal memory 35 are connected to the information processing section 31.

  The main memory 32 is a volatile storage unit used as a work area or a buffer area of the information processing unit 31 (the CPU 311). That is, the main memory 32 temporarily stores various data used for the processing based on the program, or temporarily stores a program acquired from the outside (such as the external memory 44 or another device). In the present embodiment, for example, a PSRAM (Pseudo-SRAM) is used as the main memory 32.

  The external memory 44 is a nonvolatile storage unit for storing a program executed by the information processing unit 31. The external memory 44 is composed of, for example, a read-only semiconductor memory. When the external memory 44 is connected to the external memory I / F 33, the information processing section 31 can read a program stored in the external memory 44.

The acceleration sensor 39 detects the magnitude of linear acceleration (linear acceleration) along the three-axis (xyz-axis) direction. The acceleration sensor 39 is provided inside the lower housing 11. As shown in FIG. 1, the acceleration sensor 39 is configured such that the long side direction of the lower housing 11 is the x axis, the short side direction of the lower housing 11 is the y axis, and the inner side surface (main surface) of the lower housing 11. With the vertical direction as the z axis, the magnitude of linear acceleration on each axis is detected. For example, the acceleration sensor 39 may be of the type available from Analog Devices, Inc. or ST Microelectronics NV. The acceleration sensor 39 is, for example, an electrostatic capacitance type acceleration sensor, but other types of acceleration sensors may be used. The acceleration sensor 39 may be an acceleration sensor that detects a uniaxial or biaxial direction. The information processing unit 31 can calculate the posture and movement of the mobile device 1 using data (acceleration data) indicating the acceleration detected by the acceleration sensor 39.

  Further, the mobile device 1 may include a gyro sensor instead of the acceleration sensor 39 or together with the acceleration sensor 39. The gyro sensor detects an angular velocity around a predetermined axis (for example, the xyz axis). Data representing the angular velocity detected by the gyro sensor is output to the information processing unit 31. The information processing unit 31 can calculate the attitude and movement of the mobile device 1 using data (angular velocity data) indicating the angular velocity detected by the gyro sensor.

  Further, the RTC 38 and the power supply circuit 40 are connected to the information processing unit 31. The RTC 38 counts the time and outputs it to the information processing unit 31. The information processing unit 31 calculates the current time (date) based on the time counted by the RTC 38. The power supply circuit 40 controls power from a power source (the rechargeable battery housed in the lower housing 11) of the mobile device 1 and supplies power to each component of the mobile device 1.

  In addition, an I / F circuit 41 is connected to the information processing unit 31. A microphone 42 and a speaker 43 are connected to the I / F circuit 41. Specifically, a speaker 43 is connected to the I / F circuit 41 via an amplifier (not shown). The microphone 42 detects the user's voice and outputs a voice signal to the I / F circuit 41. The amplifier amplifies the audio signal from the I / F circuit 41 and outputs the audio from the speaker 43. The touch panel 13 is connected to the I / F circuit 41. The I / F circuit 41 includes a voice control circuit that controls the microphone 42 and the speaker 43 (amplifier), and a touch panel control circuit that controls the touch panel. The voice control circuit performs A / D conversion and D / A conversion on the voice signal, or converts the voice signal into voice data of a predetermined format. The touch panel control circuit generates touch position data in a predetermined format based on a signal from the touch panel 13 and outputs it to the information processing unit 31. The touch position data indicates the coordinates of the position where the input is performed on the input surface of the touch panel 13. The touch panel control circuit reads signals from the touch panel 13 and generates touch position data at a rate of once per predetermined time. The information processing unit 31 can know the position where the input is performed on the touch panel 13 by acquiring the touch position data.

  The operation unit 14 includes the operation buttons 14 </ b> A to 14 </ b> L and is connected to the information processing unit 31. From the operation unit 14 to the information processing unit 31, operation data indicating an input status (whether or not the button is pressed) for each of the operation buttons 14A to 14I is output. The information processing unit 31 acquires the operation data from the operation unit 14 to execute processing according to the input to each operation button 14A to 14I.

  The lower LCD 12 and the upper LCD 22 are connected to the information processing unit 31. The lower LCD 12 and the upper LCD 22 display images according to instructions from the information processing unit 31 (the GPU 312). In the present embodiment, the information processing section 31 causes the upper LCD 22 to display a stereoscopic image (a stereoscopically viewable image) using the right eye image and the left eye image.

  Specifically, the information processing unit 31 is connected to an LCD controller (not shown) of the upper LCD 22 and controls the parallax barrier on / off for the LCD controller. When the parallax barrier of the upper LCD 22 is on, the right-eye image and the left-eye image stored in the VRAM 313 of the information processing unit 31 are output to the upper LCD 22. More specifically, the LCD controller alternately repeats the process of reading pixel data for one line in the vertical direction for the image for the right eye and the process of reading pixel data for one line in the vertical direction for the image for the left eye. Thus, the right-eye image and the left-eye image are read from the VRAM 313. As a result, the image for the right eye and the image for the left eye are divided into strip-like images in which pixels are arranged vertically for each line, and the strip-like images for the right-eye image and the strip-like images for the left-eye image are alternately arranged. The image arranged on the upper LCD 22 is displayed on the screen. Then, when the user visually recognizes the image through the parallax barrier of the upper LCD 22, the right eye image is visually recognized by the user's right eye and the left eye image is visually recognized by the user's left eye. As a result, a stereoscopically viewable image is displayed on the screen of the upper LCD 22.

  The outer camera 23 and the inner camera 24 are connected to the information processing unit 31. The outer camera 23 and the inner camera 24 capture an image in accordance with an instruction from the information processing unit 31 and output the captured image data to the information processing unit 31.

  The 3D adjustment switch 25 is connected to the information processing unit 31. The 3D adjustment switch 25 transmits an electrical signal corresponding to the position of the slider to the information processing unit 31.

  The 3D indicator 26 is connected to the information processing unit 31. The information processing unit 31 controls lighting of the 3D indicator 26. For example, the information processing section 31 turns on the 3D indicator 26 when the upper LCD 22 is in the stereoscopic display mode. The above is the description of the internal configuration of the mobile device 1.

[3. Peripheral device configuration]
Hereinafter, the configuration of the peripheral device 2 will be described. First, an outline of the peripheral device 2 will be described. In the present embodiment, the peripheral device 2 includes an additional function unit, an infrared communication unit, and a support unit. That is, the peripheral device 2 supports the portable device 1 by the support unit, communicates with the supported portable device 1 by the infrared communication unit, and adds a predetermined function by the additional function unit to the portable device 1. It is.

  The additional function unit is a member having a predetermined function to be added to the mobile device 1. The predetermined function of the additional function unit may be any function.

That is, the infrared communication unit 62 receives data obtained by the predetermined function (for example, operation data representing an operation on the operation unit 57, data detected by the sensor unit, data received by the reception unit, etc.). It transmits to the portable device 1 by infrared communication. Alternatively, the infrared communication unit 62 receives data (for example, image data to be displayed on the display unit) for executing the predetermined function from the portable device 1 by infrared communication. In other embodiments, one of the mobile device 1 and the peripheral device 2 may have only a transmission function, and the other may have only a reception function. That is, the infrared communication unit 62 may have only one of a transmission function and a reception function.

  The said support part is a member which supports the portable apparatus 1 so that attachment or detachment is possible. The support unit supports the mobile device 1 in a fixed manner (so that the positional relationship between the mobile device 1 and the peripheral device 2 is constant). The specific configuration of the support portion for supporting the portable device 1 may be any configuration. Although details will be described later, the support unit is positioned such that the infrared light receiving and emitting unit 27 in the portable device 1 is positioned at a position where infrared rays can be transmitted to and received from the infrared communication unit 62 of the peripheral device 2. Support. Therefore, according to the present embodiment, by attaching the peripheral device 2 to the portable device 1, infrared communication can be performed between the portable device 1 and the peripheral device 2. As a result, the function of the additional function unit in the peripheral device 2 can be added to the portable device 1. That is, according to this embodiment, the peripheral device 2 can be connected to the portable device 1 with a simple configuration without using a connector.

  Hereinafter, a detailed configuration of the peripheral device 2 will be described with reference to FIGS. 8-10 is a figure which shows the external appearance of the peripheral device 2. FIG. 8 is a plan view of the peripheral device 2, FIG. 9 is a perspective view of the peripheral device 2 viewed from the lower right front, and FIG. 10 is a perspective view of the peripheral device 2 viewed from the upper left rear.

(Description of support part)
The peripheral device 2 includes a support unit for supporting the mobile device 1. In the present embodiment, the support portion includes a wall portion 51 and a bottom surface portion 52. As shown in FIGS. 8 to 10, the bottom surface portion 52 is a member formed in a substantially planar shape. The wall portion 51 is provided at an edge around the bottom surface portion 52. Specifically, the wall 51 includes a first wall 51a, a second wall 51b, and a third wall 51c. The first wall portion 51a is provided on the upper side of the bottom surface portion 52 (the side on the y-axis positive direction side shown in FIG. 9). The second wall portion 51b is provided on the right side (the x-axis positive direction side shown in FIG. 9) and the right side of the lower side of the bottom surface portion 52. The third wall portion 51 c is provided on the left side and the left side of the lower side of the bottom surface portion 52. Hereinafter, the details of the support portion will be described.

That is, the support portion is configured to be able to support the lower housing 11. Specifically, the bottom surface portion 52 is formed in the same size as the plate-like lower housing 11. Further, the wall 51 is formed in a frame shape, and is configured such that a space surrounded by the frame-shaped portion (a space in which the lower housing 11 is inserted) has a size corresponding to the lower housing 11. That is, the wall 51 is configured such that the space is the same as or slightly larger than the lower housing 11.

  Thus, in the present embodiment, the support unit supports the housing (lower housing 11) in which the operation unit (the operation button 14 or the slide pad 15) is provided in the foldable portable device 1. In the present embodiment, when the peripheral device 2 is attached to the portable device 1, the user holds the peripheral device 2, and when the peripheral device 2 is not attached to the portable device 1, the user The lower housing 11 is gripped. Therefore, according to the present embodiment, the user grips the lower side of the mobile device 1 regardless of whether the peripheral device 2 is not attached or not. Therefore, even when the peripheral device 2 is attached, the user can use the portable device 1 in the same manner as when the peripheral device 2 is not attached, so that the peripheral device 2 becomes easier to use. In other embodiments, the support unit may support the upper housing 21 of the mobile device 1 or may support both the lower housing 11 and the upper housing 21.

  Moreover, although a support part may support any position of the lower housing 11, in this embodiment, it supports the side surface of the lower housing 11.

(See FIG. 12). Specifically, the first wall portion 51 a supports the upper side surface of the lower housing 11. The second wall portion 51 b supports the left side surface and the lower side surface of the lower housing 11. The third wall portion 51c supports the right side surface and the lower side surface of the lower housing 11. Thus, in this embodiment, since each wall part 51a-51c supports the four side surfaces of the lower housing 11, the peripheral apparatus 2 can support the portable apparatus 1 more firmly, and the portable apparatus 1 can be supported. Can be positioned more accurately.

  In the present embodiment, the wall 51 is formed so as to face only a part of the entire side surface of the lower housing 11 (see FIG. 8). That is, the wall 51 is formed so that a part thereof is opened. In the present embodiment, the wall 51 is formed by opening a position corresponding to a predetermined member provided on the side surface of the mobile device 1. The “position corresponding to the predetermined member” is a position facing the predetermined member in the mounted state. Specifically, the wall 51 in the present embodiment is open at the following positions. That is, the wall 51 is open at the left end of the upper side surface of the lower housing 11, which is a position corresponding to the L button 14 </ b> G of the mobile device 1. The wall 51 is open at the upper portion of the left side surface of the lower housing 11, which is a position corresponding to the volume adjustment switch 14 </ b> I of the mobile device 1. The wall 51 is open at the right end of the upper side surface of the lower housing 11, which is a position corresponding to the R button 14 </ b> H of the mobile device 1. The wall 51 is open at the center of the lower side surface of the lower housing 11, which is a position corresponding to the audio output terminal 29 of the mobile device 1. Therefore, according to the present embodiment, the user can use the predetermined member of the mobile device 1 even in the mounted state. That is, in the present embodiment, the user can press the L button 14G, the R button 14H, and the volume adjustment switch 14I even in the wearing state, and can insert and remove the earphone and the like to the audio output terminal 29. .

  In other embodiments, the wall 51 may be formed by opening other positions. For example, the central portion of the upper side surface of the lower housing 11, which is the position corresponding to the cover portion 11 </ b> D of the external memory 44, may be open. In addition, for example, the wall 51 may be open at the lower side of the left side surface of the lower housing 11, which is a position corresponding to the cover 11 </ b> C of the external data storage memory 45. Furthermore, in other embodiments, the wall 51 may have a shape in which no opening is formed.
