  Based on the detection result of the pop-up detection unit 900, the flash control unit 25a causes the flash light emitting unit 300 to emit illumination light toward the visual field region of the imaging device 1. Specifically, the flash control unit 25a detects whether or not the flash light emitting unit 300 is in a usable position by detecting the result of the pop-up detection unit 900, and a position where the flash light emitting unit 300 can be used, for example, a leg portion. When 17 is detected as a pop-up state from the main body unit 100, the flash light emitting unit 300 is caused to emit illumination light toward the visual field region of the imaging device 1. In addition, the flash control unit 25 a causes the flash light emitting unit 300 to emit light based on the luminance component included in the image data generated by the image sensor 8 and the brightness of the subject. Further, the flash control unit 25a causes the flash light emitting unit 300 to emit light when the flash mode is set in the imaging apparatus 1.

  The aiming control unit 25b controls the light beam emitted by the optical aiming unit 400 and the light amount of the light beam by controlling the driving of the optical aiming unit 400. Specifically, the aiming control unit 25b causes the optical aiming unit 400 to emit a light beam continuously or intermittently, and controls the light amount of the light beam. The aiming control unit 25b determines whether the mode of the imaging device 1 is in a usable position, whether the optical aiming unit 400 is in a usable position, a state in which the imaging device 1 preferably uses the optical aiming unit 400, and the like. It judges and controls the optical sighting part 400. FIG. For example, the aiming control unit 25 b causes the optical aiming unit 400 to emit a light beam according to the focal length of the imaging optical system 2. Further, the aiming control unit 25b causes the optical aiming unit 400 to emit a light beam based on the detection result of the pop-up detection unit 900.

  Subsequently, when the power switch 16a is operated and the power of the imaging device 1 is turned off (step S109: Yes), the imaging device 1 ends this process. On the other hand, when the power supply of the imaging device 1 is not turned off (step S109: No), the imaging device 1 returns to step S101.

  In Step S106, when the second release signal is not input from the release switch 16b (Step S106: No), the imaging device 1 proceeds to Step S109.

  In step S110, when the optical aiming unit 400 is being driven (step S110: Yes), the aiming control unit 25b stops the optical aiming unit 400 (step S111). After step S111, the imaging apparatus 1 proceeds to step S106.

  In step S110, when the optical sighting unit 400 is not being driven (step S110: No), the imaging device 1 proceeds to step S106.

  In step S101, when the imaging apparatus 1 is not set to the shooting mode (step S101: No), when the imaging apparatus 1 is set to the reproduction mode (step S112: Yes), the imaging apparatus 1 is a recording medium. A reproduction display process for displaying an image corresponding to the image data recorded in 19 on the display unit 18 is executed (step S113). After step S113, the imaging apparatus 1 proceeds to step S109.

  In step S101, when the imaging apparatus 1 is not set to the shooting mode (step S101: No), when the imaging apparatus 1 is not set to the reproduction mode (step S112: No), the imaging apparatus 1 performs step S109. Migrate to

The light source unit 821 is provided below the leg unit 810 and emits irradiation light with the aiming light directed obliquely upward on the subject side.

  The reflective optical element 822 is configured by a half mirror or a mirror provided with a dielectric multilayer film that reflects only light of a specific wavelength, for example, red. The reflective optical element 822 reflects the aiming light emitted by the light source unit 821 toward the back side and transmits light from the visual field region of the imaging device 1.

Furthermore, the opening 824 protects the optical sighting part 820 from external force from the outside when the leg part 810 is accommodated in the main body part 100 (pop-down state).

  FIG. 15 is a top view schematically showing the state of the cover member 824a when the leg portion 810 is accommodated in the accommodating portion 110. FIG. FIG. 16 is a top view schematically showing the state of the cover member 824a when the leg portion 810 is separated from the accommodating portion 110. FIG.

  As shown in FIGS. 15 and 16, the cover member 824 a is provided so as to be openable and closable toward the subject side with respect to the opening 824, and toward the subject when the leg 810 is separated from the accommodating portion 110.

  The optical sighting unit 820 configured in this manner projects the sighting light (aiming point) onto the reflective optical element 822 by driving the light source unit 821 in a state where the leg 800 is popped up from the main body 100. . Specifically, the reflective optical element 822 generates a virtual image of the aiming light emitted from the light source unit 821 in or near the subject area. In this case, the aiming light is projected almost at infinity with respect to the reflective optical element 822 (see the parallel light in FIG. 14). Even if the position is moved, it does not deviate from the aiming light. As a result, the photographer can frame the subject in the approximate center of the visual field region (in the image) by adjusting the aiming light to the desired subject. Furthermore, even if a desired subject is a moving subject, the photographer can easily keep the aiming light within the visual field region (in the image) of the imaging device 1 by keeping the aiming light at the subject. Further, the light source unit 821 can be moved electrically by using an element having a light emitting unit divided in a linear or planar shape without mechanically moving.

The parallax between the optical axis O of the imaging optical system 2 and the virtual image of the aiming light displayed on the reflective optical element 822 of the optical aiming unit 820 can be further reduced. For example, as shown in FIG. 17, the tip of the leg portion 800 does not retract from the field of view of the photographer, so that the sighting light displayed on the optical axis O of the imaging optical system 2 and the reflective optical element 822 of the optical sighting portion 820 The parallax L1 with the virtual image increases. On the other hand, as shown in FIG. 18, the tip of the leg portion 800 is displayed on the optical axis O of the imaging optical system 2 and the reflective optical element 822 of the optical sighting portion 820 by retracting from the field of view of the photographer. The parallax L2 with the virtual image of the aiming light can be made smaller than the parallax L1 in FIG. 17 (parallax L2 <parallax L1). Thereby, even if the focal length of the imaging optical system 2 is telephoto, the subject caused by the parallax between the optical axis O of the imaging optical system 2 and the virtual image of the aiming light displayed on the reflective optical element 822 of the optical sighting unit 820 Displacement of the sighting due to the distance up to the distance can be reduced, and the sighting light can be more reliably focused in or near the desired subject region.

  Further, when the leg portion 810 is accommodated in the accommodating portion 110, the leg portion 800 is such that the support portion 823 bends the first link 823a and the second link 823b around the third axis R3 to the photographer side. And accommodated in the accommodating portion 110 of the main body portion 100 (see FIG. 15).

  According to the fifth embodiment of the present invention described above, a desired subject can be easily framed even during telephoto shooting or super-telephoto shooting without increasing the size of the imaging apparatus 1. .

  Further, according to the fifth embodiment of the present invention, even when the photographer slightly shifts the line of sight from the position of the eye that can be aimed at the optical aiming unit 820, the live view image displayed on the display unit 18 is viewed. Therefore, it is possible to follow the subject while confirming the captured image.

  Further, according to the fifth embodiment of the present invention, since at least a part of the leg portion 800 or the main body portion 100 is retracted outside the field of view of the optical aiming portion 820 when the optical aiming portion 820 is driven, the optical aiming is performed. The field of view visible through the unit 820 is widened, the optical axis O of the imaging optical system 2 and the arrangement of the optical sighting unit 820 can be brought close to each other, and the captured image data and the parallax of the optical sighting unit 820 are reduced. be able to.
