Description

Stereoscopic-monoscopic filming system with recording up to 360 ° horizontally and 360 ° vertically, and corresponding rotating lens camera. The sector of the technique of this patent is that of the image industry obtained by direct recording of reality, possibly intervened by digital means, for the search for effects, and in order to obtain images in a 360 ° spectrum or a angle close to it, vertically and horizontally. Indication of the prior art state:

The inventors of this patent are those of the ES P9200907 patent, for "Comprehensive recording system, projection-visualization-hearing of images and / or perfected virtual reality", consisting of the projection of previously recorded images individually for each viewer, so that each one has a relative position detector and a pair of screens before their eyes, which according to said detector display the images corresponding to the point of view chosen according to the head rotation or angle sought by the eyes, with the effect of total immersion in the scene.

The ES P 9100194 by "Procedure for the projection of images with stereoscopic / monoscopic effect using projectors of the conventional type" which is based on the alternative reception of images also emitted alternately and synchronized on a screen, determining by the obturation of glasses the reception of the images for each eye belonging to each point of view. The known recording media for stereoscopic movies are limited by the need for the two lenses to capture the scene, and on the other hand because they are both in the frontal position of that scene they capture; in this way it is practically impossible to capture an area greater than 180 °; This is only possible with multiple cameras that sectorize the reading of the scene. However, a recording in these conditions, with stereoscopic effect, has many technical difficulties to the time to be both performed and subsequently displayed.

The present invention aims at a filming system and a camera intended to obtain a real filming which is provided with means to obtain said filming, by printing the set of frames that make up each image in 360 °.

The system uses cameras that can store the image in a photographic film or electronically digitized on any medium that allows it (magnetic stripe, optical support, etc.).

It is capable of capturing the scene at a horizontal angle of 360 ° so that the viewer obtains a stereoscopic view, although it also allows the recording of monoscopic images at the same horizontal angle. The possibility of capturing stereoscopic images is limited by the type of lens used. The ideal objectives for this purpose are those that cover an angle such as the human or greater visual angle.

Stereoscopic filming is achieved, covering a horizontal angle of 360 ° by means of two objectives that maintain a rotation with respect to a common axis.

It allows a perfect stereoscopic vision in the whole image and therefore avoids the phenomena of visual fatigue that occur when observing stereoscopic images captured with conventional systems.

With the system that we detail below, 360 ° can be captured horizontally and with a perfect stereoscopic vision, with a single camera equipped with two objectives that by means of an angular rotation effect a sweeping that covers 360 ° horizontal of the scene.

The vertical angle captured depends on the objective used; This is due to the fact that the objectives make a rotation and therefore an objective that captures 180 ° vertical when performing the rotation captures the 360 ° horizontal and vertical that form the scene.

As we have said, the camera captures the scene through two lenses that register a horizontal angle Minimum of the scene. The vertical angle they capture depends on their optical characteristics.

These objectives are separated from each other at a certain distance that depends on their optical characteristics and that is the one in which the best stereoscopic vision is obtained. They are fixed on a platform that rotates with respect to an axis located in the center of the distance of separation of the two objectives. The objectives are mounted on the platform so that its optical axes are practically parallel; however, the optical axes of the lenses are not exactly parallel but are provided with a convergence such that the intersection of the optical axes occurs at a distance from the camera that coincides with the horizon line at the location of the camera. The maximum convergence would be that necessary for the distance at which the horizon line lies at sea level and from the average height of the human being. If the camera is placed at a higher height, the horizon line is farther away and therefore the necessary convergence is smaller. For this reason the camera is equipped with a device for regulating the convergence of said optical axes so that it can be adapted to the particular conditions of the place where the shooting takes place. As the platform rotates, each objective is sweeping the scene that the light-receiving support captures in the form of segments

As the two objectives are sweeping the scene, they capture the elements of it with an angular difference. Thus they are recorded in the frames in different positions according to their distance from the camera. If we take as an example the previous case where the scene is formed by a tree and we add a sphere closer to the camera, two frames (one for each objective) would be obtained as shown.

The closer the objects are to the camera, each lens records them with a greater angular difference and this translates into the positions they occupy in Each frame is further away. Objects located in the visual infinity occupy the same position in both frames.

If we superimpose the two frames, the objects that are in the infinite occupy the same relative position, instead the closest ones are displaced on both sides of the previous ones. In fact, if we make the objects located in the infinity coincide with the optical axes of each eye, the closest objects occupy positions located inside the parallel lines that form the optical axes. Therefore, if the viewer wishes to focus on them, he must carry out an ocular convergence just like in reality. In order for this to be possible, all objects must be recorded clearly in the frame, that is to say, objectives of great depth of field must be used. The direction of rotation described by the platform is according to the hands of the clock, so each objective registers a frame in which the positions occupied by the objects are identical to those of human vision. If the turn is the opposite, the image obtained by the right eye is obtained on the left target and vice versa.

In this way it is achieved that the brain can the three-dimensional image of any object registered by the camera.

The minimum number of frames per second that each lens should capture is the usual one in cinematography, that is, 25 images per second (ips). To register a frame the platform, on which the objectives are located, must perform a 360 ° rotation, therefore to register 25 ips it must rotate at 1500 revolutions per minute (r.p.m.).

In case you want to slow down the image, we just have to rotate the platform to more r.p.m. , for example to capture 80 ips you must turn the platform to 4800 r.p.m ..

The horizontal angle covered by the target while the platform is still and the rpm at which it rotates when filmed, they determine the exposure time of the light capture medium. If for example the objective covers 10 °, it covers the 360 ° that form the scene with 36 segments of 10 °. Filming at 25 ips the exposure time is (1/25) * (1/36) = 0.0011 seconds. Filming at 80 ips would be (1/80) * (1/36) = 0.00034 seconds.

These short exposures force, when filmed with photographic film, to use luminous lenses and sensitive film. In the case of using electronic support, the problem with exposure is minor since these elements are extremely sensitive to light.

Filming can be done with photographic film or electronic support. In this type of camera the image that is registered by means of a rotary movement, is stored sequentially in a support that can be photographic or electronic. Therefore, it is possible to use continuous roll film or electronic support where the information is stored sequentially (magnetic strip, optical support etc.).

There can be five modalities: A) Filming with a single band of photographic film, two lenses. B) Filming with two films, two objectives.

C) Filming with a single film and a single objective.

D) Filming with two films and a single objective.

E) Continuous filming according to alternative system.

A) Filming with a single film band, two objectives.

Using film as a support allows, after filming, an electronic image processing for those systems that require it. The fact that the lenses are in continuous rotation prevents the film from being impressed in the place where the lens forms the image. Therefore, to record the scene recorded on the film, the image captured by each lens is sent, through an optical system, to the base on which the platform rotates and on which the film is located.

The optical system projects the image on the inner or outer wall of the rollers on which the film is placed. This forms a loop that wraps the rollers on which the film is dragged.

The optical system sends the one that captures the objective and makes it reach the film reaching it perpendicular to the tangent, at that point, of the rollers on which the film is dragged.

The optical systems of each lens differ in their length. This is because each lens records the image it records in a different portion of the movie. Likewise the optical systems reach the film in the same vertical of the drag rollers. In this way, and using a single film, practically the 360 ° that make up the scene can be recorded except for those necessary for the film to form the loop.

The dimensions of the frame depend on the definition you want to achieve. The length of the frame has to be equal to the width of the light segment that the objective projects on the film by the number of segments that the objective needs to cover the image. Thus, if, for example, the objective covers 10 ° of the scene, 36 segments are needed to cover 360 °. If this segment when projected on the film covers a width A the length of the frame is A * (360) / (10).

The width of the frame would be necessary to capture the vertical degrees covered by the lens without distortion.

The rollers on which the film is coupled have a larger diameter and separation the larger the definition that is to be achieved.

At the time of exposure of the frame the film must be completely still and before the exposure of the next frame must advance to prevent the new image from being impressed on the previous one. This forces, in the event that they want to register 360 °, to feed the number of revolutions per minute that the platform makes and the existence of a shutter system that prevents printing of the frame already recorded and is moving to give way to the next frame. Once the frame has been impressed, the film cannot be reached by means of the shutter. The platform makes a revolution without impressing the film and at this time the film is advanced one frame. Then the passage of the and so on is allowed. Therefore the rpm number must be doubled.

The shutters can be mechanical or electronic (eg liquid crystal) and are located between the lens and the film. In the previous example to get 25 ips should turn to 3000 r.p.m. and for 80 ips at 9600 r.p.m. With an objective that covers 10 ° and filming at 25 ips the exposure time is (1/50) * (1/36) = 0.00055 seconds. Filming at 80 ips would be (l / 160) * (l / 36) = 0.00017 seconds. These exposures are very small and therefore in rotating cameras that record the image on a single film, the most logical thing would be to reduce the angle to be covered of the scene, so that in the time that the objectives travel the blind angle is advanced the movie.

B) Filming with two films, two objectives.

There is another option, with film support, to record 360 ° and that the camera rotates at a number of revolutions per second equal to the number of images recorded at that time: Use instead of a movie two.

In this case the films are on two pairs of independent but overlapping rollers that alternately advance, that is, while one is exposed the other advances. The optical system of each lens can project the image on either of the two films.

In addition, each optical system has two light shutters (which can be liquid crystal), that is, one for each movie and acting alternately:

Left lens shutter for movie 1

Left lens shutter for movie 2 Right lens shutter for movie

Right lens shutter for the movie

A cycle would be as follows:

During the first revolution the image of the left and right lenses is recorded on the first film and for this purpose, the 012 and 0D2 are closed, preventing the film 2 from reaching. On the other hand, the 011 and 0D1 are open allowing the passage of the movie 1. While movie 1 is being exposed, movie 2 is advanced one frame, so that it is ready for exposure. In the next revolution, 011 and 0D1 are closed, preventing the arrival of the film 1. However, 012 and 0D2 are open, recording the image on film 2.

While the image is being recorded in movie 2, movie 1 is advanced one frame, so that it is ready for the second exposure.

In the next cycle, while the image is recorded on film 1 and with 012 and 0D2 closed, film 2 is advanced and so on. This cycle is repeated successively and thus we obtain the sequence of images of each objective recorded alternately in two different films.

In this case and since the sequence of each eye is recorded in two different films, a numerical code must be recorded at the same time so that phase errors are not possible.

Electronic support

The CCD is in the place where the objective form the image:

In this case, the camera's objectives project the segments of the scene directly onto an electronic CCD type sensor that is located in the place where each lens forms the image. This allows the elimination of the optical system that in the case of film filming was necessary to bring the image to the film.

This ensures that the information of the digitized image is stored as a sequence of segments. The image of each segment is stored digitized, that is, by a numerical sequence. This information can be used directly to form images in dynamic perception helmets without having to perform, as a previous step, any computer processing of the image.

The CCD is located below the platform that supports the objectives:

The CCD can be, as in the case of film filming, under the platform on which the objectives are located, thereby achieving a larger capturing surface and therefore greater definition. This option would require the optical system that carries the image without distortion to the base. The dimensions of this surface are determined in the same way as we have previously specified for the frame dimensions.

In this case the existence of dead times between the exposure of one frame and the next is not necessary. This reduces the number of r.p.m. , eliminates the need for shutters and allows to capture 360 ° getting reasonable exposures.

It is also not necessary that the optical systems differ in their length, nor the fact that they must record on the same vertical of the capture surface. In addition, the CCDs can be placed without any problem on the outer wall of the cylinder that supports them. In this way the optical systems are outside the cylinder that supports the CCDs. C) Filming with a single movie and a single lens.

It is a modification of the one described above. The most significant difference is that instead of having two objectives, separated at a certain distance, and covering 360 ° horizontal by an angular turn, it is endowed with a single objective that also covers 360 ° by an angular turn.

D) Filming with two films and a single objective.

It is a means of facilitating, as in the case of B) previously described, the drag, because it is an alternative, thus being able to obtain lower camera rotation speeds to obtain the same number of frames.

E) Continuous filming.

It consists of a periscopic system that has a light inlet that is lowered towards a film that is arranged horizontally through an optical system and mirrors that rotate internally in the same direction and at half the speed of the upper mirror that has the periscopic system.

It is formed by a 45 ° inclined mirror with respect to the optical axis that collects the light information located in the surrounding 360 °, due to its rotation at a suitable continuous speed with respect to said optical axis.

This information is collected by an optical image-forming system, and sent to an element or vehicle, which projects said image to a solidarity set of mirrors, an oblique first that receives the image and reflects it to a second, preferably parallel to the axis. optical, and a third, also oblique, that collects the information received from the second and returns it to the projection axis. The correct position in the printing of the film, or any other means of image registration, is obtained by means of the adequate rotation speed of the periscopic capture system with respect to that of the mirror assembly. In order to make clearer the explanation that will follow, twelve sheets of drawings are attached which in twenty-one figures represent the essence of the present invention.

Figure 20 shows a profile view of the camera of Figure 19. Figure 21 shows a diagram of the periscopic continuous film camera.

Figure 1 shows a diagram of the camera in plan. In it we can see indicated by the left objective, with 2 the right objective, with 3 the axis of rotation, with 4 the platform of rotation, with 5 the direction of rotation that the camera adopts, and with 6 the optical axes that are represented Parallel although later it will be seen they have a certain convergence The distance between the objectives is determined according to their focal length, and also according to the stereoscopic effect to be projected.

Figure 2 shows an outline of the camera in profile. It shows an example of the arrangement of objectives 1 and 2 on platform 4 with possible movement around the axis of rotation 3.

Figure 3 shows a camera scheme focusing an object on the visual horizon. In this figure it can be seen that the optical axes 6 are convergent, in an exaggerated manner in this representation, on the object located in the visual horizon indicated by 7.

Figure 4 shows a diagram of the scanning of the camera according to its turning movement 5. In it we can see that in position 8, objectives 1 and 2 focus a point located in a position sequentially before object 7 that is on the horizon. In position 9, the objectives here expressed as 1 'and 2', have exceeded in their angular sweep the object located on the horizon. The capture of this scene takes place by taking each of the segments of which it is composed according to the turn 5 of the camera.

Figures 5 and 7 show a diagram of the camera's focus according to the right and left lenses respectively. In them it can be seen that objective 2 in its sequences 2, 2 "and 2 'carries out a scan that determines the previous initial vision (more to the left) of point 11 by the right objective in its sequences 2 and 2", that in the case of the left objective, in which in positions 1 'and 1 "of this one in which an initial vision (more to the left) of the object of horizon 7 is appreciated. In this way the difference between the points of view of the objectives 1 and 2 that the spectator will then see with each of their eyes Figures 6 and 8 show the frame obtained for each objective according to each of the points of view explained in Figures 5 and 7.

Figure 9 shows a schematic view of the optical system and the film drive roller. The drag rollers of the film are indicated by 12, and constitute a moving drag part independent of that of the rotating platform 4, in which the projections of the different sectors taken by the objectives 1 and 2 of the chamber and driven by the optical systems of each of the objectives indicated by 13, to film 12. With 29 the shutter corresponding to the left objective is indicated and with 30 the shutter corresponding to the right objective.

Figure 10 shows a sectional view of the scheme of the optical recording system on the frame located between the drag rollers of the film for a single film, in which the details explained in Figure 9 can be seen on this different perspective. Figure 11 shows a diagram view of the film-bearing roller and the loop that forms it, so that it is possible for the film to advance when the reader system is at the blind angle of filming 16, being determined said angle by the position of the rollers 14; This scheme will not allow the image to be read in 360 °, but in a single film system it reduces the number of revolutions required and the camera system. Furthermore, said blind angle 16 functions as a light shutter.

Figure 12 shows a schematic of the result of the frames recorded by a camera using simple film indicating with II the left frame 1, 12 the left frame 2, 13, the left frame 3, etc; and with DI the right frame 1, D2 the right frame 2, D3 the right frame 3, etc.

Figure 13 shows a scheme of the double film recording system, in which 18 drag rollers of film 1 can be seen, with 19 drag rollers of film 2, with 20 the right optical system, and with 21 the left optical system, so that each optical system alternately, according to the also alternative displacements of each of the films by the drag rollers, sends the image captured by each lens alternately to each of the films, determining a uptake according to the sequence set forth in Figure 14. The shutter of the first film of the left objective is shown with 31, with 32 the shutter of the first film of the right objective, with 33 the shutter of the second film of the objective left and with 34 the shutter of the second film of the right lens.

Figure 14 shows an outline of the result of the frames recorded by a camera using double film, in which the left objective 1 frame is recorded in film 1 with II and the right objective 1 frame with DI; the film 1 moves and at the time of this movement the film 2 is recording the frame 12 with the left objective and D2 with the right objective, switching to film 1 as long as the dragging of this film 2 occurs, and so on.

Figure 15 shows a scheme of the image capture objective electronically with the flat CCD, indicated by 24. The vertical angle 25 that is capable of capturing the camera, determines on a flat projection of a spherical reality, a less deformation appreciable to the extent that the angle of capture is smaller. Figure 16 shows a schematic of the image capture objective electronically with the curved CCD indicated by 35. To avoid deformation caused by the vertical angle 25 being very wide, the curved CCD is radial to the focus, by what collects the images in real structure, that when reproduced do not produce the effect of "fisheye" that originates in the objectives of short focal length.

Figure 17 shows a diagram of the image capturing device arranging the CCD under the platform around the axis of rotation, between the optical systems of both objectives, in order to produce a recording according to electronic means in which the CCD is located in the outer part of the cylinder that supports it indicated with 26, near and around the axis of rotation indicated by 3. Figure 18 shows a diagram of the image capturing device arranging the CCD under the platform in the inner part of a cylinder arranged below said platform, around the optical systems of the objectives, in which the CCD is located inside the cylinder 27.

These two figures, which have both been represented with two objectives, determine the CCD scheme external to the optical systems or located between them; therefore they are compatible with single objective cameras. Figure 19 shows a diagram of the single-objective camera scanning 360 ° in a plan view, in which being the single objective, the acquisition is monoscopic, and the direction of rotation 28 is indifferent, determining through this camera the capture of reality in 360 °, although not in stereoscopic form, particularly useful to simplify the procedure of recording and reproduction. In addition, although they are not represented, the camera that has a single lens can be equipped with a single and double film, according to the necessary features.

Figure 20 shows a profile view of the camera of Figure 19, which, as stated above, constitutes a simplification of the double objective lens with the same viewing range benefits.

Figure 21 shows a view of the periscopic continuous film camera, in which it can be seen indicated by 36 the light information that comes through the lens, with 37 the 45 ° inclined flat rotating mirror with respect to the optical axis is indicated, which is indicated by 38. Said visual information is projected through two optical systems, one 39 imager, and another 40 which is only a vehicle of said image. Said image is projected to a solidarity set of mirrors 41,42,43 which is also rotatable; however, this assembly rotates at a speed of 1/2 with respect to the rotation of the upper mirror 37 and in the same direction. In this, a third mirror that forms an oblique angle to the upper one is indicated with 41, so that its image projects it along an acute triangular path, to an external flat mirror that is indicated with 42, and to a lower flat mirror 43 that determines the recovery of the light rays towards the bottom where the film 44 is located. The film is placed in a plane perpendicular to the optical axis determined by the imaging systems, which is located behind the mirror 43, according to the direction of light . The advance of said film is continuous, and its speed will be determined by the size of the finite fields captured by the mirror 37, and, consequently, the number of finite fields necessary to capture a horizon of 360 ° the appropriate number of times by second. The chosen pickup speed is 25 complete horizons per second. The stereoscopic camera must have a binocular system of this type.

In the practical embodiment it is possible to combine dual-lens cameras, as single-purpose cameras with one or two films, so that although the camera has a double lens and double film capability, it can record with single lens and single film, or double lens and simple film, as well as with single objective and double film and double objective and double film. The present invention is of industrial application in the film industry to obtain bi or three-dimensional images of natural scenarios especially, as well as sets, in which the capture takes place over the entire visible horizon, and in accordance with a purpose of being projected either individually by stereoscopic projection helmets, either by spherical screens, or other projection technologies.
