As a method for displaying only a captured image in distinction from other images, the captured image is set in advance to be stored in a predetermined folder in the third memory of the mobile phone 1, and the image stored in the folder is stored. May be displayed sequentially, or a flag may be set for the image file when the camera unit 21 captures and stores the image file, and only the flagged image file may be displayed.

  The light amount mode is a mode for adjusting the light amount of the light unit 22. As shown in FIG. 11A, in the light quantity mode, the left and right arrows and an indicator showing the current quantity are displayed in the horizontal direction on the bottom of the second display unit 20. Each time the user presses the second operation button 24a (brighter) or 24b (darker), the length of the indicator becomes shorter or longer, and the light amount of the light unit 22 changes accordingly. Further, when the user presses the left button (second operation button 24b) for 1 second or longer, the light emission ends. As described above, by operating the second operation button 24a or 24b, the light amount of the light unit 22 can be adjusted in a folded state without opening the mobile phone, and the operability and convenience are improved.

  Next, a procedure for adjusting the light amount of the light unit 21 using the buttons 23, 24a, and 24b provided on the back surface of the first housing 2 will be described with reference to the flowchart of FIG. Here, a process from a state in which the light amount adjustment mode is selected from the menu screen on the second display unit 20 after entering a predetermined operation and the light amount adjustment mode is entered will be described.

  First, when the light amount adjustment mode is entered, the control unit 40 reads the light amount data LX from the third memory 52 and turns on the light with the light amount based on the light amount data LX (step S (hereinafter simply referred to as S) 10. ). At this time, when the light unit 21 is already lit, nothing is changed substantially. Next, it is detected whether or not the user presses the buttons 23, 24a, and 24b provided on the back surface (S11). If the button has been pressed, the control unit 40 detects which button the user has pressed and stores it in the memory (S12). Next, the counter value I is set to 0 in order to determine whether the user has pressed the button normally (short press) or long press (S13). The counter value I is incremented by 1 after 10 msec (S14). While the user is pressing the button, the counter value I is incremented by 1 every 10 msec (S15), and when the user releases the button, the process proceeds to the process corresponding to the pressed button (S16).

  If the user has pressed the right button, the time (counter value I) during which the button has been pressed is detected (S17), and if I is greater than 100, it is determined as “long press”. In this case, since the long press of the right button is not defined, the process proceeds to SLO via S27 (S21). If I is 100 or less, it is determined whether the light quantity LX is smaller than the maximum value LX = 10 (S18). If the light quantity LX is 10 or more, the light quantity cannot be increased beyond this, so the process returns to LOOP via S27 (S21). When the light quantity LX is smaller than 10, the value of the light quantity LX is increased by 1 (S19), a bar having a length corresponding to the value of the light quantity LX is displayed on the second display unit, and the light is turned on with the light quantity LX ( S20).

  If the user has pressed the enter button, the time (counter value I) during which the button has been pressed is detected (S22), and if I is greater than 100, it is determined as “long press”. In this case, since the long press of the decision button is not defined, the process proceeds to SLO via S27 (S21). When I is 100 or less, it means that the user ends the light amount adjustment, and the light amount adjustment mode is ended with the current light amount LX.

  If the user has pressed the left button, the time (counter value I) during which the button has been pressed is detected (S23), and if I is greater than 100, it is determined as “long press”. In this case, the long press of the left button means light OFF, and the light amount LX is set to 0 (S26). When I is 100 or less, it is determined whether or not the light quantity LX is 1 or more (S25). If the light quantity LX is 0, the light quantity cannot be reduced below this level, so that the process returns to LOOP via S27 (S21). When the light quantity LX is 1 or more, the value of the light quantity LX is decreased by 1 (S25), a bar having a length corresponding to the value of the light quantity LX is displayed on the second display unit, and the light is turned on with the light quantity LX ( S20).

  When the process proceeds to LOOP (S21), the process proceeds to LOOP (28), and the light quantity adjustment is repeated again.

  FIG. 11B shows a display example when a bar having a length corresponding to the value of the light quantity LX is displayed (S20). Each time the light quantity LX increases by one, the number of display blocks increases by one from the left, and all blocks are displayed with the maximum light quantity LX = 10. A display example actually displayed on the second display unit is shown in FIG. In this way, by arranging the second display unit 22 for visually displaying the adjustment amount and the adjustment button on the same plane, the user can operate the mobile phone 1 while looking at the adjustment amount while being folded, Operability and convenience are improved. In the various adjustment modes described below, the same bar display is performed, and the user can operate the mobile phone 1 while viewing the adjustment amount in a folded state.

  The light color mode is a mode for changing the light emission color of the light unit 22. Since the light unit 22 is composed of a red LED 22R, a green LED 22G, and a blue LED 22B, light emission other than white light, for example, red, green, blue, yellow, purple, and light blue, is possible by a combination of light emission of each LED. Each time the user presses the second operation button 24a (forward feed) or 24b (reverse feed), the light unit 22 switches the emission color. Further, when the user presses the left button (second operation button 24b) for 1 second or longer, the light emission ends. As described above, by operating the second operation button 24a or 24b, the light emission color of the light unit 22 can be changed in a folded state without opening the mobile phone 1, thereby improving operability and convenience. To do.

  The voice incoming call history mode is a mode for displaying a voice incoming call history. When there is an incoming voice call in the mobile phone 1, the history is stored in the third memory 52, and it is possible to display when and from whom the call is received. The second display unit 20 displays the incoming time and the caller's telephone number or name, and the second display unit 20 every time the user presses the second operation button 24a (new incoming call) or 24b (old incoming call). The incoming call history changes. In this way, the incoming call history displayed on the second display unit 22 can be switched by operating the second operation button 24a or 24b in a folded state without opening the mobile phone 1, which is easy to use and convenient. Will improve.

  The mail display mode is a mode for browsing received mail. The second display unit 20 displays the subject and the sender, and when the user presses the second shutter button 23, the mail text is displayed. Further, every time the user presses the second operation button 24a (new mail) or 24b (old mail), the incoming call history of the second display unit 20 is switched. To end the mail display mode, the user ends when the user depresses the second shutter button 23 for a long time. As described above, the contents of the received mail displayed on the second display unit 22 can be switched by operating the second operation button 24a or 24b in a folded state without opening the mobile phone 1, which is easy to use and convenient. Improves.

  Next, a procedure for displaying the mail contents on the second display unit 20 using the buttons 23, 24a, and 24b provided on the back surface of the first housing 2 will be described with reference to the flowchart of FIG. Here, a process from a state in which the mail content display mode is selected from the menu screen on the second display unit 20 through the predetermined operation and the mail content display mode is entered will be described. Note that. In addition to the selection from the menu screen, when the mobile phone 1 receives a mail, the mail content display mode may be entered by pressing the button within 5 seconds.

  First, when the mail content display mode is entered, the control unit 40 reads the first mail from the third memory 52 and displays the sender and title of the first mail on the second display unit 20. A value MX indicating a mail number is sequentially assigned to the mail box in the memory in order from the first mail. In this case, the mail number MX is set to 1 (S30). Next, it is detected whether or not the user presses the buttons 23, 24a, and 24b provided on the back surface (S31). If the button has been pressed, the control unit 40 detects which button the user has pressed and stores it in the memory (S32). Next, the counter value I is set to 0 in order to determine whether the user has pressed the button normally (short press) or long press (S33). The counter value I is incremented by 1 after 10 msec (S34). While the user is pressing the button, the counter value I is incremented by 1 every 10 msec (S35), and when the user releases the button, the process proceeds to the process corresponding to the pressed button (S36).

  If the user has pressed the right button, the time (counter value I) during which the button has been pressed is detected (S37), and if I is greater than 100, it is determined as “long press”. In this case, since the long press of the right button is not specified, the process proceeds to SLO via S47 (S41). If I is 100 or less, it is determined whether the mail number MX is smaller than the maximum number of stored mails (S38). If the mail number MX is equal to or greater than the maximum number of stored mails, the next mail does not exist, so the process returns to LOOP via S47 (S41). When the mail number MX is smaller than the maximum number of stored mails, the value of the mail number MX is incremented by 1 (S39), and the second display unit 20 writes the mail sender and title in the display memory so as to display them. (S40).

  If the user has pressed the enter button, the time (counter value I) during which the button has been pressed is detected (S42), and if I is greater than 100, it is determined as “long press”. In this case, the long press of the enter button means that the user ends the mail display, and the mail display mode ends. When I is 100 or less, the text of the mail with the mail number MX is displayed on the second display unit 20 (S43), and the process returns to LOOP through S47 (S41).

  If the user has pressed the left button, the time (counter value I) during which the button has been pressed is detected (S44), and if I is greater than 100, it is determined as “long press”. In this case, since the long press of the left button is not defined, the process proceeds to SLO via S47 (S41). If I is 100 or less, it is determined whether the mail number MX is greater than 1 (S45). If the mail number MX is 1 or less, this is the first mail, so the process goes back to LOOP via S47 (S41). If the mail number MX is larger than 1, the value of the mail number MX is decreased by 1 (S46), and the mail sender and title of the mail number MX are written in the display memory so as to be displayed on the second display unit 20 (S40). . When the process proceeds to LOOP (S41), the process proceeds to LOOP (48) and the mail display is repeated again.

  In this way, using the three buttons, it is possible to perform operations of sending / returning the mail sender / title display, displaying the text, and ending the mail display mode.

  In the voice call history mode and the mail display mode, in addition to selecting a selection item from the standby state and entering the mode, when there is a voice call or mail reception, by pressing the second shutter button 23, It is also possible to enter the mode. When a specific display is performed on the second display unit 20 for a predetermined time from the reception of a voice call or mail, and the user presses the second shutter button 23 only when there is the specific display, the above-mentioned selection items are displayed. Instead, it can enter the voice incoming call history mode or the mail display mode.

  In addition, since the mobile phone 1 includes the TV tuner 59, the second display unit 20 can display a TV. During television display, the user can perform channel switching and volume adjustment by operating the second operation buttons 24a and 24b. Switching between channel switching and volume adjustment can be switched by pressing the shutter button 23 by the user. As described above, even when viewing the TV on the second display unit 22, the second operation button 24a and the second operation button 24a can be folded in the folded state without opening the mobile phone 1 and operating with the numeric buttons or the like when changing the channel. Since the channel can be changed by operating 24b, operability and convenience are improved.
