  In step S530, the CPU 2 determines whether or not a pressure larger than a predetermined pressure is detected based on the output of the sensor 8. When CPU 2 determines that a pressure larger than a predetermined pressure is detected (YES in step S530), CPU 2 switches control to step S532. If not (NO in step S530), CPU 2 executes control again in step S530. While the CPU 2 repeatedly executes the process of step S530, the monitor 10 displays a mail creation screen as a front screen and a shooting screen as a back screen. At this time, recording continues.

  In step S532, the CPU 2 ends the recording function. Typically, the CPU 2 ends the recording based on the fact that the user has selected a recording stop icon displayed on the operation screen 114. The monitor 10 displays a shooting screen as a front screen and a mail creation screen as a back screen.

  In step S540, the CPU 2 determines whether or not a pressure greater than a predetermined pressure is detected based on the output of the sensor 8. When CPU 2 determines that a pressure larger than a predetermined pressure is detected (YES in step S540), CPU 2 switches control to step S542. If not (NO in step S540), CPU 2 executes control again in step S540. Further, while the CPU 2 repeatedly executes the process of step S540, the monitor 10 displays the shooting screen as the front screen and the mail creation screen as the back screen.

  In step S542, the CPU 2 attaches a moving image obtained by photographing the subject to an email and transmits it to another smartphone. The monitor 10 displays a mail creation screen as a front screen and a shooting screen as a back screen.

  In addition, CPU2 does not necessarily need to perform step S540. For example, the CPU 2 switches the control from step S532 to step S542 based on the end of the recording function (step S532). That is, the CPU 2 switches the display from the shooting screen 110 to the mail creation screen 120 based on the end of the camera function.
