Abstract

PURPOSE:To freely select a picture whose three-dimensional view is necessary by linearly decomposing plural video pictures to form a synthesized picture on one photosensitive film and joining a fine parallel line pattern or lenticular plate formed with the same pitch as the synthesized picture to the synthesized picture. CONSTITUTION:A video picture tape 11 of high definition is set to a video tape recorder 12 to observe a reproduced image. A proper frame is selected at this time, and the video signal of the selected picture is recorded. A required number of negative films 14 are obtained from the recorded video signal by a film converting device 13. Negative films are linearly decomposed through a lenticular plate 16 and are synthesized on another photosensitive film. In this case, at least a pair of negative films are synthesized into a negative film 15 on the photosensitive film, and the lenticular plate 16 used for synthesis is joined to this negative film 15. Thus, a three-dimensionally viewed picture is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for producing a three-dimensional image using parallel lines or a lenticular plate, and particularly to a method for obtaining a three-dimensional image from continuously photographed video images.

<Prior art> A motor drive mechanism is attached to a still camera to photograph a subject from inside a moving object such as a car or airplane. Since lateral parallax is necessary for stereoscopic viewing, multiple images are taken of cars, etc. while moving sideways.

This is possible with a movie camera, but with the commonly used 35mm and 16mm photosensitive films, the image of each frame is small, and when it comes to this product, the resolution is poor! (&, so it is better to use a larger film (e.g. 6 x 6 size).

Since we use filmed images and the number of such images is limited, images that have been carefully calculated can be used immediately, but images taken without such consideration will have a small number of frames. , making selection difficult and not getting a good product.

If the images are retaken, more photographic film will be used and costs will increase. Furthermore, the same problem occurs even if you try to select from many photographed frames.

<Problems to be Solved by the Invention> On the other hand, there is a video IN imitation (television image) as an image that can be recorded and saved on a magnetic tape, etc. However, the current video image is one frame i! The number of horizontal lines for copying is 525, which is actually only about 480 lines.

To be frank, creating a three-dimensional image using parallel lines or a lenticular plate with this level of image density would be unbearable to view. This is because the amount of information is insufficient to create a three-dimensional image.

<Means for solving vsm> In other words, the present invention provides a fixed amount of binocular parallax from a video image having 900 or more horizontal pixels and recorded iei* taken with a video camera or a moving subject. A plurality of video images are selected, and a parallel line or lenticular plate is used to separate the plurality of video images into lines, and a composite image is formed on a single photosensitive film, and the parallel line or lenticular plate is formed at the same pitch as above. This is a method for producing a three-dimensional image, the special feature of which is to create a three-dimensional image by combining a plate with a composite image.

In addition, the present invention is not limited to creating a three-dimensional image on a photosensitive film, but also involves making a three-dimensional image original image of the photosensitive film, using photolithography, and if the original image is a color image, separating the colors to create a printing plate. , reproduce a large number of composite images using printing methods,
This also includes creating a three-dimensional image by combining parallel lines or lenticular plates based on this.

<Detailed description of the invention> The present invention will be further described in detail below.

For example, if the subject is a landscape that includes mountains, as shown in Figure 1, there will be an airplane or helicopter in front of the landscape (1).
Fly a flying object (2) like .

The flying object (2) is equipped with a high-definition video camera (3) with 900 or more horizontal lines to continuously take pictures during flight. At this time, since the position of the flying object (2) moves with respect to the scenery (1), an image corresponding to the amount of binocular parallax is automatically obtained. Video IN imitation is
Generally, the rate is 30 frames per second, so if you take pictures continuously during a 10 minute flight, for example, 10,000 to 1,000 images will be obtained. Among them, any number of different sets of images corresponding to the amount of binocular parallax can be found. Since it is a high-definition video image, you can obtain sharp image quality. Moreover, since many images can be obtained, it is possible to select an image with the required amount of parallax without having to perform sufficient calculation settings for parallax in advance.

In practice, the speed of the flying object (2) does not need to be taken into consideration so much, and there are cases where the shooting may be done not continuously but intermittently.

After the shooting is completed, we select the images necessary for stereoscopic viewing and confirm the amount of parallax.

First, play back the images recorded on a magnetic tape, etc., check which images are flowing to the left (or right) at a constant speed without shaking up and down, and select the desired image from among those images. Select (frame). A set of two images with a known frame interval is selected, the images are stored in a frame memory, and then output as a film image by a hard copy device. If you repeat this process for another image, you will now have two images with parallax.

A certain amount of parallax exists between these two images.

The amount can be measured by stacking two sheets as shown in FIG.

In Figure 2, the amount of parallax of the closest object is 2a,
Assuming that the amount of parallax of the deepest object is 2b, as a specific example, it is determined that 2ax2b=1111rnm is set, and 10 images are interpolated and synthesized between them. Parallax amount Δ2 between each image
a is =2 (mm), and the three-dimensional effect (the amount of t$) at this time is the visual distance II
I! Assuming that the distance is 40 cm, the amount of parallax xl Δ2 a X2O3 interocular distance + amount of parallax 63+Δ2a X400 63+2 -12.3 (mm) is obtained, and an apparent float (stereoscopic effect) of 12.3 mm is obtained.

From this measured value, calculate the number of images required for compositing under the lenticular plate and the frame interval of the images to be extracted.For example, assuming that it is calculated that 10 images are required at a 2o frame interval, this video signal The film image used as a hard copy to confirm the parallax during film conversion could have been something like a black and white electronic image, but the film image here is the same as one taken with a regular camera. This is a high-quality image with various colors, and a high-definition image with 900 or more horizontal lines is an image that satisfies this. Specifically, a high-definition television called Hi-Vigilan has an effective horizontal pixel count of 1035 and a vertical pixel count of 1840, and a synthesis process that satisfies these will be described.

If possible, the video signals of the selected 10 frames are recorded on another tape (if necessary, the signal is converted to the format of the film forming device), and output as the above-mentioned beautiful color film through the film forming device. These films are separated linearly through a lenticular plate in the correct order, and then combined simultaneously. By placing the lenticular plate on top of the combined color film, it is possible to create a product that allows stereoscopic viewing without using glasses or anything else. It's done.

The process of creating a three-dimensional image will be explained in detail using the flowchart shown in FIG. A high-definition video image tape (11), such as a high-definition television (HDTV), is played on a video tape recorder (12), and the reproduced image is viewed. At this time, an appropriate frame is selected and the video signal of the selected image is recorded. From this recorded video signal, a required number of original films (14) are obtained by a film forming device F (13). This original film is separated into lines through a lenticular plate (16) and composited onto another sheet of photosensitive film. At this time, at least two original films are combined onto the photosensitive film. In reality, not one set, but several sets of original film are composited onto - sheets of photosensitive film.The composite film becomes the original film (15).
By combining the lenticular vi (16) used for synthesis with 15), an image that can be viewed stereoscopically is obtained.

Furthermore, if the original film (15) is reproduced in large quantities by printing techniques and lenticular sheets are attached to each copy, this also becomes a three-dimensional image.

FIG. 4 shows the principle of stereoscopic images according to the present invention.

According to the diagram, the right K
l! (1B) and left IN (19) are the synthesized H! Right WI copy (22) and left I! of the i-film (15) or the reproduced print (20). Imitation (21)
will be viewed separately. As a result, in the viewer's mind, the left and right (21
) (22) is only a set of two images, but it is not limited to a set of - and can be used as a plurality of sets to create a more realistic three-dimensional image.

<Effects of the Invention> The video image signal can be obtained with as many as 30 frames per second, making it possible to simplify complicated calculations in advance to create a stereoscopic image, and to freely create images that require stereoscopic viewing. can be selected. Further, in the present invention, since a high-definition image is specified as a video image, even if it is converted into a stereoscopic image, it is possible to make a high-quality product that looks good.

Furthermore, there is an advantage in that even if the video images of the frames are retaken or not, the cost is lower than that of the conventional method of preparing an original by taking a camera using film.
