Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus for picking up a still image or a moving image by using an image pickup element for photoelectrically converting a subject image.

[0002]

2. Description of the Related Art Conventionally, an image pickup apparatus has been put into practical use in which a subject image is formed on an image pickup device such as a CCD to obtain a still image or a moving image of the subject.

In such an image pickup apparatus, it is difficult to lengthen the exposure time for both moving images and still images. For example, when shooting a moving image, a long time of 1/60 seconds or more is impossible. In addition, even when taking a still image, the CCD accumulates a slight electric signal that is not caused by exposure, so-called dark current, and disturbs the image. Therefore, it is difficult to take a long time like a silver salt film for 1/30 second. The exposure time is limited. Therefore, when photographing a low-brightness subject with such an image pickup device, there is a high need for the auxiliary light emitting means, and a built-in auxiliary light source,
Many external auxiliary light emitting means can be attached, which have been put into practical use.

The auxiliary light emitting means may also be used as means for enriching the expression of a subject. For example, by taking a so-called bounce emission, which intentionally shifts the emission direction of the auxiliary light emission means upward or leftward or rightward from the optical axis direction of the image pickup system to reflect it on a wall or the like, so-called bounce light emission Images can be obtained. Therefore, as the auxiliary light emitting means, one that can change the emitting direction has been put into practical use.

On the other hand, in such an image pickup apparatus, since an image pickup system, a processing system, a recording system, etc. are electrically connected to each other, suitable layout setting of the entire apparatus is easy and various apparatus forms are available. is there.

[0006] For example, in a camera-integrated VTR with a monitor disclosed in Japanese Patent Laid-Open No. 6-98210, an image pickup system is configured to be relatively rotatable independently of the main body so that the monitor screen of the main body can be seen from the front. There has been proposed an image pickup apparatus capable of shooting an image at various angles by rotating an image pickup system as it is.

Further, in another conventional image pickup apparatus shown in FIG. 8, the image pickup system 5 and the main body section 1 are connected via the vertical section 3, so that the image pickup system 5 is 360 ° about the vertical axis 3. It is configured to be rotatable. Therefore, the imaging system 5 is set to 180 °
By rotating the photographer, the photographer can photograph himself / herself while looking at the monitor screen from the front.

[0008]

However, in the above-mentioned conventional example, the image pickup system and the auxiliary light emitting means are independently constructed and rotated with respect to the apparatus main body, and are arranged in the optical axis direction of the image pickup system. No particular consideration has been given to moving the light emitting direction of the auxiliary light emitting means integrally with respect to the apparatus main body.

Further, the bounce light emitting function of the auxiliary light emitting means is also set on the assumption that light emission is made to the subject existing in front of the photographer, and therefore there is a limit to the rotation range, and the entire rotation range of the image pickup system is limited. I couldn't cover it.

As described above, in the conventional image pickup apparatus, even if it has the auxiliary light emitting means, it may interfere with the image pickup depending on the position condition of the object. Especially, in the image pickup apparatus provided with the monitor in the main body, the image pickup is convenient. Therefore, the high performance having the above is lost.

The present invention has been made in order to solve the above-mentioned problems of the prior art. It is possible to directly emit auxiliary light to a subject or bounce light emission, and it is possible to take a picture by an easy operation. It is an object of the present invention to provide an image pickup device in which the image pickup means and the auxiliary light emitting means are provided on the main body so as to enable the above.

[0012]

Therefore, an image pickup apparatus according to the present invention is an image pickup apparatus which is provided with an image pickup device for photoelectrically converting a subject image and which takes a still image or a moving image, and which is provided with an image display means. And a head portion rotatably connected to the main body portion through a rotation mechanism, and the head portion is provided with an image pickup means having the image pickup element and an auxiliary light emitting means for emitting auxiliary light. The optical axis of the image pickup means and the light emitting direction of the auxiliary light emitting means integrally rotate with respect to the main body when the head section is rotated with respect to the main body. In addition to the above configuration, the head unit has a shift mechanism capable of relatively changing the light emitting direction of the auxiliary light emitting unit with respect to the optical axis direction of the image pickup unit. Achieve the purpose of It is Utosuru thing.

[0013]

With the above construction, when the photographer operates the head portion, the optical axis direction of the image pickup means and the light emitting direction of the auxiliary light emitting means can be integrally rotated with respect to the main body portion. It is possible to easily carry out the image pickup in which the auxiliary light is emitted in conformity with.

Further, according to the above-mentioned structure having the shift mechanism,
In addition to the direct irradiation of the auxiliary light matched with the imaging direction, the bounce emission angle can be easily set in the reflector direction.

[0015]

1 is a perspective view showing the structure of a photographing camera according to an embodiment of the present invention.

Reference numeral 1 is a head portion, and 2 is a main body portion. The head part 1 is connected to the main body part 2 via a vertical shaft 3 and a horizontal shaft 4, and is rotatable about the vertical part 3 by 360 °.
Further, it is configured to be rotatable up to 90 ° about the horizontal shaft 4. An image pickup system 5 and auxiliary light emitting means 6 are set in the head unit 1, and another operation system 8, a monitor 9, and a control system, a recording system, a power supply, etc., which are not shown, are set in the main body unit 2.

The image pickup system 5 is housed in the head unit 1,
An imaging lens that forms a subject image on the image sensor, a diaphragm that adjusts the amount of light to the image sensor, a shutter that opens and closes the imaging optical path, and an image that converts the formed subject image from light to electricity and outputs an image signal. Equipped with elements.

The auxiliary light emitting means 6 is fixed on the head portion 1 via the platform 7, and when the platform 7 is moved, the light emitting direction 6
1 can be rotated upward or leftward and rightward with respect to the optical axis direction 51 of the imaging system 5.

The operation system 8 has a switch for instructing the camera to start photographing and various switches for inputting various information.

The monitor 9 displays the subject image that has been converted from light to electricity through the image pickup device. The photographer operates the operation system 8 while observing the subject image from the direction facing the monitor 9 to perform photographing.

A photographing operation according to the embodiment of the present invention having the above configuration will be described.

First, in normal photographing, as shown in FIG. 2, the subject 10 is present in front of the photographer. Therefore,
The photographer is to take the optical axis direction 51 of the imaging system 5 and the auxiliary light emitting means 6
The light emitting direction 61 of is directed to the front of the image pickup apparatus, the operation system 8 is operated, and the subject 9 is photographed while observing the subject image on the monitor 9.

Next, as shown in FIG. 3, when a subject 10 such as a tall tree exists diagonally above the photographer, the photographer operates the head unit 1 to move the optical axis direction 51 of the image pickup system 5 in the direction. Aim diagonally above the imaging device. At this time, the light emitting direction 61 of the auxiliary light emitting means 6 is also rotated integrally with the optical axis direction 51 of the imaging system 5 and is directed obliquely upward. Therefore, the photographer can shoot while observing the subject image on the monitor 9 by illuminating the auxiliary light toward the subject 10 diagonally above while keeping the natural posture facing the front. Even when the subject 10 exists in the left-right direction of the photographer, it is sufficient to operate the head unit 1 in the same manner to direct the optical axis direction 51 of the imaging system 5 to the subject.

Especially, in so-called "face-to-face photography" in which the photographer photographs while observing himself on the monitor 9,
As shown in FIG. 4, the photographer only needs to rotate the head unit 1 by 180 degrees. At this time, the auxiliary light emitting means 6
It goes without saying that the light emitting direction 61 of is also directed to the photographer himself who is the subject 10.

Next, a case where the auxiliary light emitting means emits a bounce light to take an image will be described.

First, as shown in FIG. 5, when the subject 10 is in front of the photographer, the photographer places the head unit 1 in front of the image pickup device so that the optical axis direction 51 of the image pickup system 5 faces the subject 10. Turn. Then, the platform 7 is operated to direct the light emitting direction 61 of the auxiliary light emitting means 6 to the wall 11. In this state, the operation system 8 is operated to photograph while observing the subject image on the monitor 9. Then, the auxiliary light is bounced on the wall 11 and the subject 1
It can reach 0, and a captured image with a more natural feeling can be obtained.

Next, as shown in FIG. 6, when the subject 10 moves to a high position, the photographer operates the head unit 1 to direct the optical axis direction of the image pickup system 5 obliquely above the image pickup apparatus. At this time, the light emitting direction 61 of the auxiliary light emitting means 6 is also rotated integrally with the optical axis direction 51 of the image pickup system 5, and is directed diagonally upward of the image pickup device while keeping the bounce angle toward the left.

Therefore, the photographer can take a picture while observing the subject image on the monitor 9 in a natural posture facing the front while maintaining the bounce angle.

Also, in the case of "face-to-face photography" in which the photographer takes a picture while observing himself / herself on the monitor 9, as shown in FIG. If the auxiliary light is reflected from the wall surface 11 or the ceiling by changing the light emitting direction 61 of the light emitting means 6, it is possible to perform the face-to-face shooting with the bounce light emission. In this case, the auxiliary light emitting means 6
Since the light emission direction 61 of does not directly face the photographer himself who is the subject 10, the photographer does not have to be dazzled by the light, and it is possible to perform better face-to-face photographing.
