Description

  The present invention relates to video shooting (hereinafter referred to as stereoscopic shooting) having depth information when a stereoscopic view is to be obtained in combination with a lenticular, a dedicated liquid crystal monitor, or the like.

Conventional stereoscopic photography is performed by linearly arranging cameras and lenses on a rod-shaped jig as shown in FIG.
The elements that realize stereoscopic viewing are pluralistic, but the most important element is left-right parallax. Stereoscopic imaging creates a video with left-right parallax from an actual subject. The obtained video is played back for stereoscopic viewing. There are a method of using special glasses and a playback method of realizing stereoscopic viewing with the naked eye using an image barrier such as a lenticular lens or liquid crystal.
Autostereoscopic viewing uses a lenticular lens and an image barrier to distribute the images that enter the left and right eyes. For the distribution, the captured images are processed and arranged according to the characteristics of the lenticular and the image barrier.
In order to obtain natural and good stereoscopic vision with autostereoscopic viewing, the number of cameras to be photographed is better, and multi-lens or super-multi-angle photographing is desired.

However, according to the above technique, the distance between the lens centers is defined by the camera / lens width. Since the upper limit of FIG. 21 is defined in relation to the subject, it was not possible to shoot at fine intervals.
Accordingly, an object of the present invention is to provide means for enabling photographing at a narrow pitch and realizing multi-view stereoscopic viewing.

In order to solve the above problems, the first invention is a photographing method in which lens portions are arranged in a “W” shape in photographing for obtaining a stereoscopic view.
In the second invention, the image obtained by the first invention is not an image from a horizontal row of viewpoints, but a viewpoint wavy in the vertical direction. General lenticular and image barriers are premised on a horizontal row of images. The second invention is an image processing for reproducing the image of the viewpoint wavy up and down in the “W” shape obtained by the first invention as it is without performing any special work.
The third invention is a lenticular product created using an image obtained by the previous processing.
4th invention is fixing jigs, such as a camera for the 1st term photography.

According to the first invention, since the lens interval is not defined by the width of the camera lens, a captured image with a narrower pitch can be obtained. As a result, multi-view stereoscopic viewing is realized.
According to the second invention, the resolution of the human eye is maximized in the horizontal direction and gradually decreases in the vertical and diagonal directions, and the video of the viewpoint shifted in the vertical direction is also arranged horizontally and reproduced. To do. The vertical displacement is not only perceivable, but the viewpoint image shifted in the vertical direction is input to the eyes at the same time, so that smooth motion parallax is generated and a good stereoscopic view is obtained.

One embodiment of the present invention is shown in FIG.
The camera 2 is arranged obliquely upward with respect to the camera 1 so that the maximum width of the main body does not overlap. Depending on the shape of the camera used, it is possible to shoot at a narrow pitch that is approximately twice that of the conventional method.

"Other embodiments"
In the embodiment of FIG. 1, the cameras are arranged in two rows vertically, but in other embodiments, the number of cameras may be three or more as shown in FIG. The “W” shape is a symbolic description of the diagonal arrangement, and the same applies to the “N” arrangement as shown in FIG. 3-2.

It is an example of the camera arrangement | positioning by the 1st and 4th invention, and its jig | tool. It is an example of the stereoscopic imaging method by a prior art. It is another Example of 1st invention and 4th invention.
