BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a portable terminal device according to an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a mobile phone will be described as an example of a mobile terminal device.
[0010]
1 to 3, reference numeral 1 indicates a mobile phone as one embodiment of the present invention.
In the mobile phone 1, a first housing 2 and a second housing 3 are arranged so as to overlap each other, and the first and second housings 2 and 3 are arranged in the thickness direction of each of the housings 2 and 3. It is connected so as to be rotatable around the extending shaft 5. The mobile phone 1 has a position between a closed position where the inner surfaces 6 and 9 of the first and second housings 2 and 3 face each other and an open position where each of the inner surfaces 6 and 9 is exposed to the outside. The positions of the housings 2 and 3 can be changed. A display unit such as an LCD connected to a built-in board 16 is provided on the outer surface (surface opposite to the inner surface 6) 8 of the first housing 2 when each of the housings 2 and 3 is placed in the closed position. 12 and a speaker unit 17 are provided.
[0011]
At one end of the inner surface 6 of the first housing 2 in the longitudinal direction, an imaging window 13 of a built-in imaging device 11 is provided so as to be exposed to the outside, and a flash window 14 for use as a flash is provided. , Are arranged adjacent to the imaging window 13 in the width direction of the first housing 2. The imaging device 11 includes a zoom function (imaging range switching unit) that can continuously change the imaging range from telephoto to wide-angle.
Further, on the inner surface 9 of the second housing 3, various operation keys 19 such as numeric keys and a microphone section 18 are provided.
[0012]
In the mobile phone 1 according to the present embodiment, a rectangular mirror 15 (reflecting plate) is installed on the inner surface 6 between the imaging window 13 and the flash window 14 and the shaft 5. The mirror 15 is provided at a position depressed from the inner surface 6 of the first housing 2 by a certain dimension, for example, about 0.1 to 0.5 mm. Further, the mirror 15 is configured as a half mirror, and its surface is provided with a total of eight marks 27a and 27b (display means) at four corners and four near the center. The area surrounded by the four marks 27a at the four corners and the area surrounded by the four marks 27b near the center indicate a two-stage imageable range. The marks 27a and 27b are illuminated by light from behind, so that their indications become clear. When no light is irradiated, the marks 27a and 27b are inconspicuous.
[0013]
Behind the mirror 15 on which the marks 27a and 27b are provided, LEDs (display means) 25a and 25b connected to the substrate 16 are separately arranged to face the respective marks 27a and 27b. Thus, when the LEDs 25a and 25b are driven to emit light, the light is applied to the marks 27a and 27b, so that the display of the marks 27a and 27b stands out. Therefore, by driving and controlling the predetermined LEDs 25a and 25b, the marks to be distinguished can be switched to the marks 27a at the four corners or the marks 27b near the center.
[0014]
Further, the mobile phone 1 is configured such that an imaging function, a telephone function, and other various functions are controlled by the control device 20. The control device 20 includes a control unit (display control unit) 21 that switches between the LEDs 25a and 25b to be driven, that is, the area defined by the mark according to the shooting range of the zoom function. The control unit 21 controls the marks 27 a and 27 b indicating the area of the image reflected on the mirror 15 in accordance with the setting of the zoom function of the imaging device 11. Further, the mark 28 is also displayed on the display surface 12a of the display unit 12 under the control of the control unit 21.
[0015]
Next, the operation of the mobile phone 1 according to the present embodiment thus configured will be described.
From the state where the first and second housings 2 and 3 are placed in the closed position, for example, when a call is received by receiving an incoming call signal, the operator of the mobile phone 1 operates the first and second housings. The call is started by disposing the housings 2 and 3 at the open position, pressing a predetermined operation key 19, and bringing the speaker unit 17 close to the user's ear and the microphone unit 18 close to the user's mouth.
[0016]
Further, when the imaging device 11 is used to photograph a distant scenery, a person, or the like as a subject from a state where the first and second housings 2 and 3 are placed in the closed positions, the first and second cases are used. Are arranged at the open position. Then, by pressing the predetermined operation key 19 while pointing the display unit 12 and the operation key 19 toward the user and the imaging window 13 toward the subject, and visually recognizing the captured image displayed on the display surface 12a, the imaging device 11 is started to perform photographing. In this case, since the mark 28 is displayed on the display surface 12a, it is possible to confirm whether the subject is placed in an appropriate imaging range. Further, when the zoom function is used, the display area for displaying the mark 28 and the imaging range by the zoom function are appropriately set in advance, so that the display area of the mark 28 is changed according to the imaging range by the zoom function. Therefore, an appropriate range of the subject can be always photographed.
[0017]
Further, when the operator takes his or her own subject as a subject, for example, to photograph his / her own face, the operator presses a predetermined operation key 19 so that the operator faces the four corner marks 27a under the control of the control unit 21. The disposed LED 25a is driven. Then, the light emitted from the LED 25a irradiates the mark 27a with light from behind the mirror 15, and the display becomes clear via the mirror 15. In this state, the inner surface 6 of the first housing 2 and the outer surface (the surface opposite to the inner surface 9) 7 of the second housing 3 are directed to themselves, and the imaging window 13 is made to face the operator's face. Place in position. Then, in order to confirm the imaging range, the user captures his / her face on the mirror 15 and adjusts the angle at which the mobile phone 1 is gripped so that the user's face is placed in the area indicated by the mark 27a. In a state where the face is arranged in the area, a predetermined operation key 19 is pressed to perform photographing.
[0018]
When the zoom function is driven to reduce the imaging range, the driving of the LED 25a is turned off under the control of the control unit 21, and the LED 25a is arranged at a position facing the mark 27b near the center. The LED 25b is driven appropriately, and the display of the mark 27b becomes clear via the mirror 15. In this state, a face or the like is photographed in the area indicated by the mark 27b and photographed. Thereby, appropriate shooting can be easily performed according to the imaging range. Further, since the marks 27a and 27b that stand out according to the imaging range can be switched, it is possible to prevent the image projected on the mirror 15 from being difficult to see due to unnecessary marks.
[0019]
Even when the mobile phone 1 is not used as a telephone or the like, the mirror 15 is disposed on the inner surface 6 of the first housing 2 and the mirror 15 functions as a normal mirror. , 3 can be used as a hand mirror by holding them in the open position. Since the mirror 15 is provided so as to be buried by a predetermined dimension from the inner surface 6, the surface of the mirror 15 is not damaged by the rotating operation when the two housings 2 and 3 are opened mutually. . In a state where both the housings 2 and 3 are in the closed position, the surface of the mirror 15 is covered by the inner surface 9 of the second housing 3 and the mirror 15 itself is hidden inside. The mirror 15 can be protected from external impact even if it is stored in a portable device.
[0020]
Note that, in the above embodiment, the case where the zoom function capable of switching the imaging range can be changed continuously has been described. However, instead of this configuration, the telephoto and wide angle are configured to be switched stepwise. You may.
In addition, the number of marks 27a and 27b is eight in total, but is not limited to this, and may be changed as appropriate.
Further, the imaging range is switched in two stages, but is not limited to this, and may be switched in three or more stages, or may be switched continuously by another configuration. In this case, switching is possible. The number of marks and LEDs provided on the mirror 15 may be set appropriately according to the number.
Also, instead of performing the half mirror processing on the entire area of the mirror 15, only the mark part may be subjected to the half mirror processing. By doing so, the reflectance of the mirror is close to the total reflection, and the visibility is improved.
Furthermore, although the lens portion 13 and the flash window 14 are provided on the first housing 2, the invention is not limited to this, and they may be provided on the outer surface 7 of the second housing 3.
In the present embodiment, the rotary type mobile phone 1 has been described as an example, but a slide type in which the first housing 2 slides upward with respect to the second housing 3 from the state of FIG. It is needless to say that the present invention is not limited to the mobile phone 1 but can be applied to other mobile terminal devices such as PDAs.
[0021]
