  In step S105, the display control unit 225c causes the rear display unit 217 to display a live view image corresponding to the image data generated by the image sensor 203.

  FIG. 5A is a diagram schematically illustrating a situation when framing a subject while viewing a live view image displayed on the rear display unit 217 of the imaging apparatus 1. FIG. 5B is a diagram schematically illustrating a situation when framing a subject on the wide-angle side of the lens unit 3 while viewing a live view image displayed on the rear display unit 217 of the imaging device 1. FIG. 5C is a diagram schematically illustrating a situation when the subject is photographed while viewing the live view image displayed by the rear display unit 217 of the imaging device 1. In FIG. 5A, a region Z1 indicates the maximum field angle that can be captured by the lens unit 3, and a region Z2 indicates the current field angle of the lens unit 3.

  As shown in FIG. 5A, when the photographer intends to photograph a subject A1 such as a bird with a composition such as an image W1 with the imaging device 1, the photographer first starts the lens operation unit 310 as shown in FIG. 5B. To move the imaging direction of the imaging apparatus 1 while viewing the live view image W2 so that the subject A1 falls within the angle of view of the lens unit 3 and gradually moves the lens. The composition of the subject A1 is determined while the angle of view of the section 3 is narrowed down to the telephoto side, and shooting is performed. In this case, the photographer tries to shoot while adjusting the angle of view of the lens unit 3 and the imaging direction of the imaging device 1 in accordance with the flight course or moving speed of the subject A1, but the flight course of the subject A1 is random and the subject A1 When the moving speed is fast, it is difficult to adjust the angle of view of the lens unit 3 to the subject, so the subject A1 escapes outside the angle of view of the lens unit 3, and only the image W3 shown in FIG. 5C can be taken. In the worst case, the subject A1 was lost. This is because the live view image displayed on the rear display unit 217 is displayed at the current angle of view (imaging angle of view) of the lens unit 3, and the rear display unit 217 generates image data after the image sensor 203 generates image data. This is a time lag until the image is displayed or a time lag from the operation of the photographer until the image is reflected on the imaging apparatus 1.

  In step S106, the display control unit 225c stops the display of the built-in display unit 215a. Accordingly, when the photographer performs framing of the subject while viewing the live view image displayed by the rear display unit 217, power consumption by the built-in display unit 215a can be suppressed.

  Thereafter, when the inside of the screen of the rear display unit 217 is touched via the touch panel 211g (step S107: Yes), the imaging control unit 225b causes the imaging device 1 to perform still image shooting (step S108). At this time, the imaging control unit 225b records the position information detected by the position information detection unit 212, the direction information detected by the direction detection unit 213, and the date / time information input from the clock 218 on the recording medium 219 in association with the image data. To do.

  Subsequently, when the power switch 211a is operated and the power supply of the imaging apparatus 1 is turned off (step S109: Yes), the imaging apparatus 1 ends this process. On the other hand, when the power switch 211a is not operated and the power of the imaging device 1 is not turned off (step S109: No), the imaging device 1 returns to step S101.

  In step S107, when the inside of the screen of the rear display unit 217 is not touched via the touch panel 211g (step S107: No), when the release signal is input from the release switch 211b (step S110: Yes), the imaging device 1 moves to step S108.

  In step S107, when the inside of the screen of the rear display unit 217 is not touched via the touch panel 211g (step S107: No), when the release signal is not input from the release switch 211b (step S110: No), imaging is performed. The apparatus 1 moves to step S109.

  In step S111, the display control unit 225c stops the rear display unit 217. Accordingly, when the photographer performs framing of the subject via the eyepiece display unit 215, power consumption by the rear display unit 217 can be suppressed.

  Subsequently, the view angle calculation unit 225a calculates the current view angle of the lens unit 3 based on the lens information of the lens unit 3 (step S112).

  Thereafter, the display control unit 225c displays a live view image corresponding to the image data generated by the image sensor 203 on the built-in display unit 215a (step S113), and a frame corresponding to the view angle calculated by the view angle calculation unit 225a. Is superimposed on the live view image and displayed on the built-in display unit 215a (step S114). After step S114 in FIG. 4, the imaging device 1 proceeds to step S110.

And the frame T1 corresponding to the angle of view calculated by the angle of view calculation unit 225a is displayed on the built-in display unit 215a. At this time, the display image displayed on the built-in display unit 215a is projected onto the optical element 215b so that the display image displayed on the built-in display unit 215a forms a virtual image of the frame T1 in the field of view of the imaging device 1 or in the vicinity of the field of view. Can be generated. Thus, by aiming the frame T1 at the desired subject A1, desired framing can be performed on the subject A1 shown in FIG. Further, as shown in FIG. 8, the photographer confirms a wide field of view through the eyepiece unit 215c and the optical element 215b, and the image M11 that can be actually photographed while aiming the subject A1 with the frame T1. You can also check the composition. Thereby, even when the imaging apparatus 1 performs telephoto shooting, it is possible to perform framing on the subject A1 while aiming at the desired subject A1.

  In step S101, when the imaging device 1 is not set to the shooting mode (step S101: No), when the imaging device 1 is set to the reproduction mode (step S115: Yes), the imaging device 1 is a recording medium. A reproduction display process for reproducing the image data recorded in 219 is executed (step S116). After step S116, the imaging apparatus 1 proceeds to step S109.

  In step S101, when the imaging device 1 is not set to the shooting mode (step S101: No), when the imaging device 1 is not set to the reproduction mode (step S115: No), the imaging device 1 performs step S109. Migrate to
