DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0010]
(First embodiment)
FIG. 1 is a perspective view of the imaging apparatus of the present embodiment, and shows a view when a display unit 7 having a display screen such as an LCD is accommodated. 2 and 3 are perspective views of the imaging apparatus according to the present embodiment, and show a use state of the display unit 7. FIG. As shown in FIGS. 1 to 3, the imaging apparatus according to the present embodiment has a substantially rectangular parallelepiped shape that is long in the height direction (perpendicular to the horizontal plane).
[0011]
FIG. 4 is a block diagram of the imaging apparatus of the present embodiment. In FIG. 4, the lens unit 1 is for entering a subject image as described above, and the image sensor 2 photoelectrically converts the subject image received from the lens unit 1. The control unit 8 is configured by a CPU or the like, and performs overall control of the entire imaging apparatus. The camera signal processing unit 3 generates a luminance signal and a color difference signal by performing matrix processing on the output signal from the image sensor, and performs processing such as gamma processing and A / D conversion.
[0012]
The image storage unit 4 stores a signal processed by the camera signal processing unit 3 and is configured by a magnetic tape or a semiconductor memory. The display unit 7 has a substantially rectangular display screen configured by an LCD or the like as described above, and displays an image captured by the image sensor 2 or an image stored by the image storage unit 4. The display signal generation unit 5 converts the signal from the camera signal processing unit 3 or the image storage unit 4 into a predetermined format and generates a signal for causing the display unit 7 to display an image. The display drive unit 6 causes the display unit 7 to display an image based on the signal generated by the display signal generation unit 5.
[0013]
The detection SW 9 is a switch for detecting whether or not the display unit 7 is in a state as shown in FIG. 7 to be described later, and detects a rotation angle by the hinge unit 10 and the hinge unit 11 of the display unit 7.
[0014]
1 to 3, the hinge unit 10 is rotatable about an axis X substantially parallel to the incident optical axis of the lens unit 1, and is rotated about 90 degrees about the axis X from the state of FIG. 1. As shown in FIG. In FIG. 2, the hinge portion 11 is rotatable about an axis Y that is substantially perpendicular to the incident optical axis of the lens portion 1 (which is also substantially perpendicular to the axis X). Further, the state shown in FIG. 3 is obtained by sliding the display unit 7 in the vertical direction from the state shown in FIG. In the state of FIG. 3, the photographer can perform stable photographing by grasping the opposite side surface on which the display unit 7 is installed. Further, since the longitudinal direction of the display screen of the display unit 7 and the longitudinal direction of the video camera main body can be accommodated in a substantially parallel manner, the display unit 7 having a large display screen can be mounted.
[0015]
Here, the structure of the hinge part 11 is demonstrated using FIG. 5 and FIG.
[0016]
FIG. 5 is an enlarged view of the hinge portion 11 when the display portion 7 is at the position shown in FIG. The hinge portion 11 that can rotate around the axis Y is constituted by a slide member 11a and a rotation member 11b. The slide member 11 a is fixed to the imaging device main body, is slidable with respect to the guide member 7 a of the display unit 7, and connects the imaging device main body and the display unit 7. The rotating member 5b is located at the center of the lateral side surface of the display unit 7, and when the slide member 11a and the rotating member 11b are fitted and integrated as shown in FIG. The display unit 7 can be rotated about the axis Y.
[0017]
FIG. 6 is an enlarged view of the hinge portion 11 when the display portion 7 is at the position shown in FIG. In FIG. 6, the slide member 11a and the rotation member 11b are separated, and the slide member 11a has moved to the other end surface of the guide member 7a. At this time, since the connecting portion between the imaging apparatus main body and the display unit 7 is only the slide member 11a, the display unit 7 does not rotate. That is, in the state suitable for image capturing as shown in FIG. 3, the display unit 7 is fixed without rotating in the Y-axis direction, so that the image is always captured while confirming the captured image in a stable state. Can do. Further, in the state of FIG. 6, since the position of the display unit 7 and the lens unit 1 for entering the subject light is close as shown in FIG. 3, the optical axis shift is improved and appropriate photographing is executed. Can do. It can also be placed on the ground or fixed on a tripod.
[0018]
FIG. 7 is a view showing a state in which the display unit 7 is rotated 180 degrees from the state shown in FIG. 1 using the hinge unit 11 and the display screen is directed outward. This state is suitable when the image stored in the image storage unit 4 is reproduced and displayed. When it is detected that the display unit 7 is in the state of FIG. 7 because the detection switch 9 is ON, the control unit 8 causes the display signal generation unit 5 to display the display unit 7 as shown in FIG. The display of the image on the display screen is rotated 90 degrees from the normal display state (display state where the horizontal plane of the image is displayed corresponding to the longitudinal direction of the display screen) displayed in FIG. A command to display the image at a reduced size is issued.
[0019]
On the other hand, when the display unit 7 is in the state as shown in FIG. 3, that is, when the detection switch 9 is OFF, the control unit 8 performs normal display on the display signal generation unit 5 (the horizontal plane of the image is the display screen). The display state is displayed corresponding to the longitudinal direction).
[0020]
Thus, when the display unit 7 displays an image in the state of FIG. 7, the image is displayed in accordance with the horizontal direction of the upright state of the imaging apparatus main body, so that it is not unsightly.
[0021]
In the present embodiment, the display means corresponds to the display unit 7. The first member corresponds to the hinge 10. The second member corresponds to the hinge 11. The control means corresponds to the control unit 8.
[0022]
【The invention's effect】
As described above, according to the present invention, a large display unit can be mounted even in an imaging device that is long in the height direction. In addition, it is possible to provide an imaging apparatus that can fix the display unit to perform imaging and can perform appropriate imaging by improving the optical axis deviation.
