  • the user Y inserts the hand Y1 into the opening section 20C from below, and so holds as to cover the gripping portion 20A and a part of the enclosure 10a of the camera body 10 with the palm of the hand Y1 (refer to Figs. 7C and 20A).
  • a thumb of the hand Y1 is put on a part of an external surface of the grip 20 or a part of a back side surface of the camera body 10.
  • Stable high-angle shooting is enabled by extending an arm (a right arm) Y2 upward in a state in which the image pickup unit 1 is held with the hand Y1 in such a manner.
  • the grip 20 since the grip 20 is equipped with the projector 21, image display by projection mapping is allowed to be performed.
  • the projector 21 may be used as illumination; therefore, shooting in a dark place is enabled.
  • the user Y is allowed to change from this high-angle shooting to low-angle shooting without holding the image pickup unit 1 in another way (in a state in which the hand Y1 remains inserted in the opening section 20C of the grip 20).
  • the user Y extends the arm (the right arm) Y2 upward, and gradually lowers the arm Y2 (refer to Fig. 20B) from a state in which the grip 20 is held (refer to Fig. 20A).
  • the grip 20 is allowed to be rotated (rotated about the shaft A2 in Figs. 10A and 10B) by tilting a wrist downward without releasing the palm from the gripping portion 20A of the grip 20.
  • the user Y is allowed to perform low-angle shooting while holding the image pickup unit 1 (the camera body 10) with the hand (the right hand) Y1.
  • the user Y may change from the high-angle shooting to the low-angle shooting, or the hand Y1 may be inserted into the grip 20 in the position P2B.
  • the user Y may so hold the grip 20 as to hold the gripping portion 20A from above the grip 20 (refer to Figs. 7C and 20A).
  • the thumb may be put on a part of the enclosure 10a of the camera body 10. Accordingly, stable low-angle shooting is allowed to be performed.

  • the accessory 110 has an adjustment mechanism 110a that is allowed to change an angle of the smartphone 120.
  • an image picked up by the camera body 10 is allowed to be displayed on, for example, a display surface 120a of the smartphone 120. Therefore, for example, during handheld shoot, the user Y is allowed to perform shooting while checking an image being shot on the display surface 120a of the smartphone 120.
  • the smartphone 120 is supported by and fixed to the accessory 110 to allow the display surface 120a to face toward the back side of the image pickup unit 1.
  • the smartphone 120 is supported by and fixed to the accessory 110 to allow the display surface 120a of the smartphone 120 to face toward a top side of the image pickup unit 1.
  • the angle of the adjustment mechanism 110a is adjusted depending on a shoot angle to change the direction of the display surface 120a of the smartphone 120. Accordingly, the user easily sees an image displayed on the display surface 120a both during high-angle shooting and during low-angle shooting.
  • the grip 20 is rotatable about the shaft A1; therefore, for example, a change from the place-and-shoot style (the position P1) to the handheld shoot style (the position P2A) is allowed to be easily performed. Therefore, the user is allowed to easily change the shoot angle with use of the grip 20, and shooting at various angles is allowed to be achieved.
  • hand movement during shooting easily affects an image.
  • hand movement is reduced by the connection section 10c (a hinge portion) (vibration is absorbed in the hinge portion) by holding not only the camera body 10 but also the grip 20. Therefore, in the handheld shoot style, deterioration in image pickup quality caused by hand movement is allowed to be reduced in the image pickup unit 1.
  • the camera body 10 is not directly held with the hand (only the grip 20 is held); therefore, compared to a case where the camera body 10 is directly held, the camera body 10 is less likely to be dropped.
