[0067]
In the state S7, the display of the EVF 20 is off and the display of the LCD 10 is off. In this state S7, since the eyepiece is not detected by the eyepiece sensor 406 of the EVF 20, the LCD 10 and the EVF 20 are not displayed. Here, when an eyepiece is detected, the process proceeds to state S8, and when the menu button 34 is pressed, the process proceeds to state S9. When the display changeover switch 31 is set to “EVF”, the state shifts to state S1, and when the display changeover switch 31 is set to “LCD”, the state shifts to state S3.
[0068]
In the state S8, the display of the EVF 20 is on and the display of the LCD 10 is off. In this state S8, since the eyepiece is detected by the eyepiece sensor 406 of the EVF 20, the EVF 20 is displayed. That is, when the eyepiece is detected by the eyepiece sensor 406 from the state S7 in which no image is displayed on the LCD 10 and the EVF 20, only the EVF 20 is activated. When the eyepiece is no longer detected, the process proceeds to state S7, and when the menu button 34 is pressed, the process proceeds to state S9. When the display changeover switch 31 is set to “EVF”, the state shifts to state S1, and when the display changeover switch 31 is set to “LCD”, the state shifts to state S3.
[0069]
