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 taking a three-dimensional video image as a so-called "stereophotograph (stereo pair)", and more particularly to a three-dimensional image used for positioning the image at the time of three-dimensional shooting. The present invention relates to a positioning device.

[0002]

2. Description of the Related Art A conventional stereoscopic image pickup / visual apparatus has been configured as shown in FIG. In FIG. 16, 10
Reference numeral 1 denotes a television camera, and a first prism means 102 is arranged in front of the television camera 101. The television camera 101 and the first prism means 102 constitute a photographing means 103 for photographing the same subject as two pairs of independent optical images having parallax between the left and right in the same screen. The video signal composed of the left and right optical images obtained by the photographing means 103 is temporarily recorded in, for example, a VTR 104 or directly introduced into a reproducing means 105 having one color television picture tube. The reproducing means 105 reproduces the left and right independent optical images 107L and 107R corresponding to the left and right sides of the independent subject on the common screen 106, respectively.

A second prism means 108 is provided in front of the screen of the reproducing means 105. The left and right reproduced optical images on the screen 106 of the picture tube of the reproducing means 105 are provided through the prism means 108. 107L, 10
7R are simultaneously observed independently and separately by the corresponding left and right eyes. In this manner, the left and right eyes allow the subject to observe an optical image having a required right and left parallax, thereby allowing the user to observe the image. The brain allows these images to be viewed as a synthesized stereo image.

[0004] In the above-described apparatus, the shooting of a stereoscopic image has been performed based on the experience and intuition of the photographer. The same applies to the case of photographing with two cameras for the right eye and the left eye and processing these images.

[0005]

As described above, in the conventional photographing, the right-eye image and the left-eye image are taken based on the experience and intuition of the photographer when photographing. For this reason, although a stereoscopic video visual device such as a stereoscopic television can be confirmed by bringing the device to the shooting site, there is a problem that the image capturing device alone does not know how the stereoscopic image looks when actually viewed stereoscopically.

[0006] Specifically, a point to be aware of at the shooting site is a shift in the height direction between the two left and right images. If there is a difference between the heights of the right-eye image and the left-eye image, it becomes difficult to associate the left and right images, and it becomes extremely difficult to view stereoscopically when viewed with a stereoscopic image visual device. This is surprisingly difficult to understand at the time of shooting, and it often happens that the shooting is done in a state where it can not be seen later. That is, there is a problem that the photographing is performed without noticing the vertical displacement.

[0007] Also, when a photographed image is viewed with a stereoscopic image visual device, what is seen in the context is, in particular, whether the photographed image is in front or behind the screen of the stereoscopic television, that is, the screen surface. Is unknown at the shooting site, so experienced photographers can take pictures with intuition, bring in a monitor that can actually view stereoscopically, or adjust the amount of deviation between the two images later It was very difficult to edit. That is, it is very difficult for ordinary people to easily take a stereoscopic image because of the above-described confirmation and processing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and an object thereof is to make it possible to capture a three-dimensional image very easily and accurately without causing a shift in the height direction between the left and right images. It is an object of the present invention to provide a stereoscopic image positioning device capable of performing the operation.

2a turns into a video signal. Here, how the image is captured can be confirmed by the small monitor (LCD monitor) 4.

The position of the left and right images is adjusted by changing the distance of the video camera 3 to the subject, changing the zoom ratio of a zoom device (not shown) of the imaging lens 11, or moving the knob 20. Then, when confirming with the stereoscopic video photographing template 1 arranged on the screen of the small monitor 4, a part of the main subject coincides with each center (intersection of lines) of the left and right crosses of the template 1 at the same time. After the adjustment, stereoscopic photography is started.

For example, as shown in FIG. 4 (A), when photographing a woman with the sea in the background, the center of the left and right crosses is adjusted so as to fit the right eye of the woman at the same time, and then this adjustment is performed. Next, as shown in FIG. 4 (B), the composition is taken into account when taking a picture.

The video thus captured is input to the three-dimensional stereoscopic video signal converter 40 shown in FIG. 3 and is first converted into an RGB signal, and then converted by the A / D signal conversion circuit 44 into an A / D signal.
It is D-converted and stored in the two-dimensional memory 45. Then, from among these, the image is temporarily enlarged by the timing controller 48 at an arbitrary timing and at an arbitrary magnification, and then cut out.

The left-eye video signal and the right-eye video signal cut out from the original video and enlarged to fill the screen are alternately left-field video signals and right-eye video signals for each field.

Assume that the input signal is processed.

That is, referring to FIG. 4, the signal input from the video camera 3 to the three-dimensional stereoscopic video signal converter 40 is shown in FIG. 4C, in which the dL and dR portions are respectively cut out and enlarged. 4D and 4E are converted into a left-eye video signal and a right-eye video signal, and the video shown in FIG. 4D and FIG. In this way, the output is output from the three-dimensional stereoscopic video signal converter 40. At this time, the position where the input video is cut or enlarged is usually processed with a preset value.

FIG. 4 shows an image captured by the video camera 3 using the stereoscopic system including the video camera 3, the three-dimensional stereoscopic video signal converter 40, the VTR 50, the television receiver 60, and the glasses 70 with shutters. In the case of trying to view the scene a stereoscopically as shown in FIG. 1A, first, as shown in FIG. 1, the mounting portion 16 of the stereoscopic imaging adapter 2 is fitted to the filter mounting screw portion of the imaging lens of the main body of the video camera 3. And attach them together.

Then, a scene a (image of a woman against the sea) as shown in FIG. 4A is photographed. At this time, as described above, the horizontal axis line 7 of the stereoscopic imaging template 1 is used.
And the right vertical axis line 8R and the left vertical axis line 8L are adjusted at the same time, for example, to the right eye of a woman at the same time as shown in FIG. I do. This adjustment is performed by changing the distance of the video camera 3 to the subject, changing the zoom ratio of a zoom device (not shown) of the imaging lens, or moving the knob 20 of the adapter for stereoscopic photography 2.

The image thus photographed is shown in FIG.
The main subject, the woman, is aligned with the left and right lines 8L and 8R as shown in the figure, but the background palm tree, yacht, clouds, etc. are slightly shifted due to the parallax of the left and right eyes depending on the distance. I have. This video is output as a video signal by the video camera 3 and is converted into a three-dimensional stereoscopic video signal converter 40.
Is processed according to the preset value described above, and is output as a stereoscopic video signal.

The stereoscopic video signal processed in this manner is projected on a television receiver 60, and the stereoscopic vision can be obtained by viewing the stereoscopic video signal with glasses 70 with shutters as shown in FIG. Here, as shown in FIG. 6, a three-dimensional stereoscopic video signal conversion device is used so that the video captured by the stereoscopic imaging template 1 at the center thereof can be seen from the cathode ray tube (screen) a little in front. Forty preset values are set. That is, when the two images on the left and right are displayed on the television receiver 60, if the shift amount L is zero, they can be seen on the cathode ray tube (screen). In the apparatus of the present invention, a main subject, that is, a “female” is displayed so as to be seen as a stereoscopic image at a position slightly before the cathode ray tube (screen).
