BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup device having a monitor display.

[0002]

2. Description of the Related Art Generally, an image pickup device such as a video camera has
A subject confirmation part called a viewfinder is provided, but this viewfinder is usually configured so that the display of a small display element with a small screen can be seen through the eyepiece, which makes it difficult to see the display. I have

On the other hand, recently, an image pickup apparatus has been proposed which has a monitor display and is capable of taking an image while looking at the screen of the monitor display. FIG. 4 is a perspective view showing an example of what is conventionally considered as an image pickup device having a monitor display.

In this image pickup device, a monitor display 1 is detachably attached to an image pickup device main body (handy type video camera in the figure) A.
By engaging the shoe engaging member 2 provided on the lower side surface thereof with the monitor mounting shoe 3 provided on the upper surface of the image pickup apparatus main body A, the screen 1a is moved to the rear side of the image pickup apparatus main body A (viewfinder a). Is attached to the image pickup apparatus main body A in a state in which the image pickup apparatus A is oriented in the direction of looking at.

The captured image of is displayed on the monitor display 1.

The image pickup apparatus shown in FIG. 4 has the monitor display 1 mounted on the upper portion of the image pickup apparatus main body A. As this type of image pickup apparatus, a rear portion or a side portion of the image pickup apparatus main body is provided. It is also considered that the monitor display is mounted with its screen facing the rear of the main body of the image pickup device.

Further, as an image pickup apparatus having a monitor display, conventionally, one side edge portion of the monitor display is pivotally supported on a side surface of the image pickup apparatus main body by a rotary shaft, and the monitor display is arbitrarily set with respect to the image pickup apparatus main body. A structure provided so as to be rotatable at an angle has also been proposed (Actual exploitation 61-103).
968 gazette).

[0008]

However, a monitor display such as the image pickup device shown in FIG. 4 mounted on a monitor display with its screen facing the rear of the image pickup device main body is a monitor display for the image pickup device main body. Since the posture of the monitor is always constant, it may be necessary to look at the screen of the monitor display from an oblique direction depending on how the camera is held with respect to the subject (how the camera is held). There was a problem that the display on the display became difficult to see.

As a monitor display of a handy type image pickup device, it is desirable to use a liquid crystal display for displaying an image using a liquid crystal panel in order to reduce its weight, but the TN currently widely used. As is well known, since the (twisted nematic) type liquid crystal panel has a narrow viewing angle, when the monitor display is a liquid crystal display, the display on the display becomes almost invisible from an oblique direction.

On the other hand, in an image pickup machine in which the monitor display is rotatably provided at an arbitrary angle with respect to the image pickup apparatus main body, the attitude of the monitor display with respect to the image pickup apparatus main body can be arbitrarily adjusted. If the attitude of the monitor display is adjusted accordingly, the screen of the monitor display can be viewed from the front side in an easy-to-see state.

However, this image pickup device has a problem that if the attitude of the monitor display is changed during image pickup, the shake of the image pickup device, which is generally called "hand shake", causes a blur in the imaged image.

That is, the above-mentioned image pickup device can be operated by holding the image pickup device main body with one hand, but in order to obtain a good image pickup without blurring, the image pickup device main body is supported by the other hand and the image pickup device is held by both hands. It is preferable to stably hold and image.

However, in this image pickup device, the posture of the monitor display cannot be changed while the image pickup device is held by both hands. Therefore, in order to change the posture of the monitor display during image pickup, one hand should be used. The monitor display has to be rotated away from the main body, so that the camera body is held by one hand and "hand shake" occurs while the attitude of the monitor display is adjusted.

The present invention has been made in view of the above situation, and its purpose is to stably hold both hands and perform good image pickup without blurring, and moreover, to hold both hands. An object of the present invention is to provide an imaging device in which the attitude of the monitor display can be adjusted while being held at, and the screen can be oriented in a direction that is easy to see.

[0015]

According to another aspect of the present invention, there is provided an image pickup apparatus in which an image pickup apparatus main body for picking up an image of a subject and a monitor display are rotatably connected to each other and the monitor display side has the image pickup apparatus main body. And a handle part for supporting the monitor display side with another hand and for rotating the monitor display in an arbitrary direction with respect to the imaging device main body.

[0016]

In other words, the image pickup device of the present invention can hold the image pickup device body with one hand and the handle portion on the monitor display side with the other hand, and the image pickup device body and the monitor display can be rotated. Since they are movably connected, by holding the image pickup device main body with one hand and holding the handle part with the other hand, it is possible to stably hold the image pickup device with both hands and perform good image pickup without blurring. Also, since the attitude of the monitor display can be easily adjusted by using the handle part, the attitude of the monitor display can be adjusted while holding the imaging device with both hands, and the screen can be oriented in a direction easy to see. .
