Instead of providing the two shutter buttons 13a and 13b, one shutter button may be provided on the side of the mobile phone 100 so that input is possible even when the mobile phone 100 is folded or opened. .

  The open / close detection unit 14 is detection means for detecting whether or not the mobile phone 100 is folded. As shown in FIG. 2A, a small protrusion 14a is formed in the vicinity of the hinge 32 at the lower part of the first casing 30, and a small hole 14b is formed in the vicinity of the hinge 32 at the upper part of the second casing 31. Yes. A switch 20 having the structure shown in FIG. 3 is provided inside the hole 14b. The open / close detection unit 14 includes a protrusion 14a, a hole 14b, and a switch 20.

  FIG. 3A is a cross-sectional view of the switch 20. The switch 20 includes a conductive portion 21, a contact portion 22, and a support portion 23. A conductive material such as a conductive rubber is used for the conductive portion 21, and the support portion 23 made of an elastic material is spaced from the contact portion 22 by a predetermined distance. Is supported. As shown in the plan view of FIG. 3B, comb-shaped electrodes 22 a and 22 b are used for the contact portion 22. The comb electrodes 22 a and 22 b are formed on the substrate 24 inside the second housing 31 at positions corresponding to the holes 14 b, and are connected to the control unit 1. When the cellular phone 100 is folded, the protrusion 14 a of the first housing 30 enters the hole 14 b of the second housing 31, and the protrusion 14 a presses the conductive portion 21 against the contact portion 22. At this time, the conductive portion 21 is in contact with a portion indicated by a two-dot chain line in FIG. 3B, and the comb electrodes 22 a and 22 b are electrically connected via the conductive portion 21, whereby a current flows between the comb electrodes 22 a and 22 b. Flows. The controller 1 determines that the mobile phone 100 is folded by detecting this current. When the cellular phone 100 is not folded, since the protrusion 14 a is not in the hole 14 b, the conductive portion 21 is separated from the contact portion 22 by the elastic force of the support portion 23. At this time, since no current flows between the comb electrodes 22a and 22b, the control unit 1 determines that the mobile phone 100 is not folded. Note that the switch 20 is not limited to the above-described structure, and the open / close detection unit 14 is not limited to the above-described configuration, and may be any configuration that can detect whether the cellular phone 100 is folded.

  The antenna 15 transmits and receives voice data, character data, image data, and the like when performing wireless communication with the base station via wireless radio waves. The radio unit 16 demodulates data received from the base station via the antenna 15 at the time of reception, and modulates and amplifies character data and image data sent from the communication control unit 17 at the time of transmission, It transmits to the base station via the antenna 15. The communication control unit 17 sends received data such as character data and image data demodulated by the wireless unit 16 to the control unit 1 based on a predetermined communication protocol. Received data from the other party received via the wireless unit 16 and the communication control unit 17 is stored in the second memory 5.

  Control of the 1st and 2nd display parts 8 and 9 is demonstrated. The control unit 1 switches the display unit that displays an image based on the image data temporarily stored in the first memory 4 based on the detection result of the open / close detection unit 14. When the opening / closing detection unit 14 detects that the cellular phone 100 is folded, the control unit 1 outputs the image data from the first memory 4 to the second display driver unit 7, and the second display unit 9. Display an image on. When the open / close detection unit 14 detects that the cellular phone 100 is not folded (opened), the control unit 1 outputs the image data from the first memory 4 to the first display driver unit 6. An image is displayed on the first display unit 8.

  As described above, the imaging unit 2 is provided outside when the mobile phone 100 is folded. Therefore, when imaging a subject other than the user of the mobile phone 100, the user opens the mobile phone 100. Then, the imaging unit 2 is imaged toward the subject on the side opposite to the user. In this state, the open / close detection unit 14 detects that the mobile phone 100 is open, that is, is not folded, and an image based on the image data output from the imaging unit 2 is displayed on the first display unit 8. . As a result, the user can use the first display unit 8 as a viewfinder during imaging.

  On the other hand, when the user himself / herself is imaged as a subject, the user images the imaging unit 8 toward the user side with the cellular phone 100 folded. In this state, the open / close detection unit 14 detects that the mobile phone 100 is folded, and an image based on the image data output from the imaging unit 2 is displayed on the second display unit 9. Thus, the user can use the second display unit 9 as a viewfinder at the time of shooting.

  As described above, since the display units 8 and 9 used as a finder at the time of imaging are appropriately switched when the user only folds or opens the mobile phone 100, the user can switch between the display units 8 and 9 as in the prior art. There is no need to operate the switching button, the user's trouble when switching the display units 8 and 9 used as a finder can be saved, and operability and convenience are improved.

  Note that the mobile phone 100 may include a switching button for switching the display units 8 and 9 used as a finder. The switching button is arranged in the vicinity of the key operation unit 12 or is assigned to any key of the key operation unit 12. When the user operates the switching button while the mobile phone 100 is open, the display units 8 and 9 used as a finder are switched. For example, when the display unit used as the finder is the first display unit 8, when the user presses the switching button, the display unit is switched to the second display unit 9, and when the display unit used as the finder is the second display unit 9, When the user presses the switching button, the display is switched to the first display unit 8.

  The control of the first and second shutter buttons 13a and 13b will be described. Based on the detection result of the open / close detection unit 14, the control unit 1 switches the shutter button whose input is valid. When the opening / closing detection unit 14 detects that the cellular phone 100 is folded, the control unit 1 validates the input of the second shutter button 13b. When the opening / closing detection unit 14 detects that the mobile phone 100 is open, the control unit 1 validates the input of the first shutter button 13a and invalidates the input of the second shutter button 13b. In order to invalidate the input of the first and second shutter buttons 13a and 13b, for example, the first and second shutter buttons 13a and 13b are fixed so that the user cannot operate the first and second shutter buttons 13a and 13b. The instruction signal from the first and second shutter buttons 13a and 13b is controlled by the control unit 1 so that the instruction signal from the first and second shutter buttons 13a and 13b to the control unit 1 is not output without fixing the 13b. It can be realized by a method such as not processing.

  As described above, the imaging unit 2 is provided outside when the mobile phone 100 is folded. Therefore, when imaging a subject other than the user of the mobile phone 100, the user opens the mobile phone 100. Then, the imaging unit 2 is imaged toward the subject on the side opposite to the user. In this state, the open / close detection unit 14 detects that the mobile phone 100 is open, and the instruction from the first shutter button 13a becomes valid. The user operates the first shutter button 13a disposed on the same side as the first display unit 8 while looking at the first display unit 8 as a finder.

  On the other hand, when imaging a subject other than the user, the user images the imaging unit 2 toward the user with the cellular phone 100 folded. In this state, the open / close detection unit 14 detects that the cellular phone 100 is folded, and the instruction from the second shutter button 13b is valid. The user operates the second shutter button 13b disposed on the same side as the second display unit 9 while looking at the second display unit 9 as a finder.

  In this way, the instruction from the first or second shutter button 13a, 13b located on the same side as the first or second display unit 8, 9 used as a viewfinder is valid simply by folding or opening the mobile phone 100. Therefore, the user can input while looking at the first or second shutter button 13a, 13b, and the operability is improved.

  In general, since the shutter button located on the opposite side of the display unit used as a finder is difficult to see from the user, it is erroneous when the user grips the mobile phone 100 or performs an operation other than the shutter button input. May be entered. In the present embodiment, since the instruction from the second shutter button 13b located on the opposite side of the first display unit 8 used as a viewfinder is invalidated simply by opening the mobile phone 100, an erroneous operation by the user can be prevented. .

  Note that when it is detected that the mobile phone 100 is open, the input of the second shutter button 13b may be validated without being invalidated. In this case, the user can operate both the first and second shutter buttons 13a and 13b. In addition, since the first shutter button 13a is disposed inside when folded, the user cannot operate when the cellular phone 100 is folded. Therefore, the input of the first shutter button 13a when the open / close detection unit 14 detects that the cellular phone 100 is folded may be either invalid or valid.

  The control of the first and second backlights 10 and 11 will be described. The control unit 1 switches on and off the first and second backlights 10 and 11 based on the detection result of the open / close detection unit 14. When the open / close detection unit 14 detects that the mobile phone 100 is folded, the control unit 1 turns on the second backlight 11 and increases the luminance of the second display unit 9. When the open / close detection unit 14 detects that the mobile phone 100 is open, the control unit 1 turns on the first backlight 10 and increases the luminance of the first display unit 8.

  As described above, when the user captures an image of a subject other than the user himself / herself, the first display unit 8 is used as a finder, and the image data captured from the imaging unit 2 is displayed on the first display unit 8. At this time, the first backlight 10 is turned on, and the luminance of the first display unit 8 is increased.

  On the other hand, when the user images the subject as the user himself / herself, the second display unit 9 is used as a viewfinder, and the image data captured from the imaging unit 2 is displayed on the second display unit 9. At this time, the second backlight 10 is turned on, and the luminance of the second display unit 9 is increased.

  As described above, when the cellular phone 100 is folded or opened, the backlight for supplying light to the display unit used as a finder is turned on, so that the displayed image is easy to see and visibility is improved.

  FIG. 4 is a flowchart showing the imaging process of the mobile phone 100. Note that the cellular phone 100 can be set to a so-called imaging mode in which imaging can be performed by a predetermined operation from the folded state or the opened state.

  First, in step S <b> 1, the control unit 1 determines whether or not the mobile phone 100 is folded based on the detection result of the open / close detection unit 14. If it is opened without being folded, the process proceeds to step S2, and if it is folded, the process proceeds to step S8. In step S2, the first backlight 10 is turned on. In step S3, the image data captured from the imaging unit 2 is displayed on the first display unit 8, and the process proceeds to step S4.

  In step S <b> 4, the control unit 1 determines whether or not the mobile phone 100 is folded based on the detection result of the open / close detection unit 14. If it is open, the process proceeds to step S5. If it is folded, the first backlight 10 is turned off and the image display on the first display unit 8 is stopped, and the process proceeds to step S8.

  In step S5, the control unit 1 invalidates the input of the second shutter button 13b and detects whether or not the first shutter button 13a is pressed. If it has been pressed, the process proceeds to step S6, and if not, the process proceeds to step S7. In step S6, the image data temporarily stored in the first memory 4 is stored in the second memory 5, and the process proceeds to step S7. In step S7, the control unit 1 determines whether or not a predetermined operation for ending the imaging mode has been performed by the user. If the operation has been performed, the process ends.
