Description

CAPTURING AND RECORDING OF IMAGE AND SOUND

The purpose of the present invention is a device for the capture and recording of both image and sound that works automatically, reducing and even eliminating the need of staff for the equipment operation. Its aim is as well a system for the capture and the recording of both images and sound specially designed to be used in public places with minimum or even no need of staff to operate the equipment.

BACKGROUND AND APPLICATION FIELDS

The humanity is continuously looking for new ways of communication. The means to achieve them have been one of the pillars of the revolution that the man has been suffering since more than five hundred years, in an exponential evolution process. In this way, the telegraph has been the origin for the telephone and the latter one for the radio which has been the source for the television, etc, in a process of growing guiddiness.

Undoubtedly, what the electronics added to that process accelerated even more the results, creating a division between the communication media: actually, there are traditional media (such as papers, magazines, etc.) and electronic ones. In the last segment, it's concentrated the huge production mass of content. What is defining a new era in humanity are the electronic media: the one of Digital Convergence.

Each one of the eletronic media has had its speciality for years, but the digitalization of the production process made the barriers disappear. This process is called Convergence. This phenomenon is the central axis of the cultural revolution that we are living and the conducting thread for the merger, fusion, acquisition and alliances processes which the companies related to electronic media are experiencing. The interactivity as idea, and later as a social value, appears in the center of the electronic media which are going through the Convergence Process. As a concept, the interactivity summarizes a step ahead in the culture evolution, converting the communication receivers into living actors of a process. Internet is the maximum expression of this concept.

Nowadays, all of the electronic media redefine their contents from the point of view of an increase in the interaction with their receivers. The radios and the newspa- pers started this process, adding to their traditional communication channels (air and printed paper) the digital and interactive version in internet. However, the interaction levels in television are low because of the technical im^¬ possibility of this medium to adapt itself to the actual needs. There is, at present, an interaction need situation required by the public and a lack of response from the television media.

The present invention arises from the need described as a way to solve the communication return from the receivers in an unidirectional medium such as television.

Besides, the automation of the recording of public participation makes arise a new communication medium which is not limited to the television productions. The device of this invention can be useful, for example, in the following fields: tourist services, creation of audiovisual material for commercial use or private one in Internet, and, in general, in any circumstance which requires the audiovisual recording of one or more people who are using the device. The present invention will also be very useful for the interaction in a network connection of similar kind enabling the transmission on air between devices such as the one of the invention or towards other media. For instance, the transmission on air of records towards the central control of television channels may cause a new jump in the communication media evolution.

In relation to the technics status, when automatic devices of audiovisual records are looked for, the most recent background is a semi-manual videocamera placed in a containing structure such as a box which has controls on one of its sides. These controls are operated by the user who must press the recording start key, place himself in the point which considers the most approppriate to issue its record and then operate again the controls to turn off the videocamera. This makes that the records obtained in this way have a bad quality due to optical aberrations for the lack of distance and illumination control indications in the recording process. Besides, it's impossible to de- termine the duration of the recording. The recording is made directly in the VCR tape of the videocamera.

Another background is the images capture system represented by, for example, the small rooms placed in subway stations or other public places which take pictures automa- tically after paying the required amount. In addition to producing just photographical records, the fidelity of the images is far from being excellent because the same depends, between other factors, on the distance left between the camera and the person who is being photographed. At less than 80 cm, the recording of a face have a distortion, with optical aberrations due to the exaggerated perspective with which the lens must work. If the minimum distance is 2 meters (which is the minimum distance in which no optical deformations are perceived over a face), the monovolume gets too big, and it's almost impossible to place it in public places because it obtructs the circulation of people.

DESCRIPTION OF THE INVENTION

The purpose of the present invention is an automatic device for the capture and recording of both images and sound which produces records in an audiovisual format which operative features make it an autonomous product of individual use not requiring human resources. The present invention was conceived to make independent the OB vans, the news reporters and the cameramen from the job of recording people. With the device of this invention, the cost of immobility of the equipment required to that end is greatly lower.

The main innovation presented in this invention is the automation and integration of the features of audiovisual recording, illumination, instructions display and, optionally, the issuance of tickets when pressing a button, being able to get the whole sequence after introducing a token or a coin in the system. Traditionally, for the above mentioned jobs, it's necessary, at least, the work of 5 people, namely: the cameraman, the person in charge of the sound, another for the illumination, the news reporter and a promoter. In its most elemental way, the present invention is an automatic device for the capture and recording of both images and sound which comprises a containing structure of the whole set with the following parts:

a) a computer provided with a system which sinchronizes the operation and controls the automation, connected to a power supply.

b) a videocamera connected to the computer.

c) a monitor connected to the videocamera and to the com- puter.

d) a microphone connected to the videocamera and to the computer, and finally:

e) one or more illumination devices connected to the computer.

The containing structure of the set is the physical support which holds and offers a spatial cohesion to the different components of the device. Its shape can vary according to the needs of the particular use that will have. Figure 1 shows a special way of performance of the invention, in which the containing structure of the set (a) has a smooth shape at the front and at the back, more vertically than horizontally developed and having in its base a place for the computer (b) , over which supports are placed (c) for the illumination equipment (d) (two in this example, placed on each side of the camera) . Immediately above the supports (c) it s found the compartment (e) for the videocamera (f) . At the front, above the videocamera (f) it's placed the microphone (g) . At the top of the containing structure of the set (a), it's placed the return monitor (h) with the screen addressed to the front of the unit. Figure 2 shows the same performance but from a side-back perpective.

It is clear that the relative arrangement of the different components of the device and their place in the containing structure of the set can vary without modifying the inventive concept. For instance, the lighting equipment (d) can be three, two of them placed at the very top of the containing structure (a) and the third above the microphone (g) or below the videocamera (f) . Anyway, the computer (b) can be placed either laterally or at the front regarding the containing structure of the set (a) , and in a different location other than the base.

The materials used for the containing structure can be different, such as resins, plastic, metal, etc. For the invention, the containing structure of the set (a) is made of an internal framework of aluminium outlines and a plastic shell. The computer controls the automation of the device. To optimize its functions, it can be provided with a processing board to synchronize the electromechanical operations which act as interface of the system. As it can be neces- sary to have the audiovisual records in a different support other than the videocamera tape, the computer may be provided with a CD-ROM or DVD recording device or another one. This option is specially useful when the automatic device for the capture and recording of images and sound is lo- cated in a public place so that the person who is using it can take the record with him/her. Additionally, the information can be recorded in the hard disk of the computer or in another hard disks which are part of the automatic device for the capture and recording of sound and images that may have a connection to internet which allows to send the produced record to a distant location (as well as receiving information) . With the same purpose, the computer may be connected to a similar devices network.

The videocamera (f) can be of any kind of the ones that are available in the market. The one conceived for the invention is digital of the Mini DV type. In the same way, the monitor (h) which function is to provide the operation instructions and show the record which is being performed can be any of the models known. It's better to have a flat 15" monitor .

The microphone (g) has the function of capturing sounds, for example, the speech of the transmitter. Different types of microphones available in the market are suitable for this purpose. Since it could be necessary to reduce the environmental sounds, a particular type of microphone suitable for the present invention is the ultradirectional external one, which is the one appearing in Figure 1.

The purpose of the lighting equipment (d) is to improve the light which is available in the environment and get a better quality recording. Besides, and since it is turned on only during the recording, it's possible to know the recording time and its turning off indicates the end of the recording. There are different kinds of lamps suitable which are used for the audiovisual recordings, as well as, in the cinema and TV industries. Due to its properties, the lighting equipment which is preferred for this use is the cold light dimmer tubes.

Since one of the aims of the present invention is to increase the independence of the images and sound recording, in another example of performance, in the containing structrure of the set, it's available a start mechanism by means of introducing tokens or coins connected to the computer. This mechanism enables the user to introduce the payment amount and in the same act to start the recording. In a preferred performance of the invention, the start mechanism by introducing tokens or coins enables the operation of the device for the images and sound capture and recording for a preset time.

Additionally, in the containing structure of the set, it may be available a mechanism to issue a recording proof connected to the computer. This mechanism entitles the user to receive a bill for the use of the device, a number or a code to participate in a contest, etc.

The aim of this invention is to have as well a system for the capture and recording of both images and sound in public places. The system for this use is designed as mod- ules or units to be easily carried and makes it versatile as to place it occupies .This design feature in units is a real advantage with relation to the former system of mono- volumes for the photographs taking. Due to the system of the present invention, it's possible to achieve the neces- sary distance to produce an image of good quality without the need of building monovolumes of huge dimensions, and at the same time, it offers the user a better comfort because he/she is not confined to a reduced space. The system of image and sound recording and capture in public places com- prises at least a) a record unit composed of an automatic device for the capture and recording of images and sounds, as previously described, and b) a transmitter unit composed of a support which acts as a floor in which the following are fixed:

i) a seat for the individual acting as transmitter.

ii) A background panel, located behind the seat that is visually obstructing what's happening at the back, and

iϋ) Two acoustic isolating panels, located on each side of the seat for the transmitter, oriented to the front-back axis of each seat, fixed to the background panel that isolates the transmitter from the environmental sound.

Figure 3 represents a special example of the system performance in which it's shown the recording unit (x) and the transmission unit (y) . In the transmission unit (y) the seat (j) is fixed to. the support acting as floor (i), and behind the seat, the background panel (k) . The seat (j) is the place in which the transmitter will be located (1) so it must comply with the following requirements: it must allow the transmitter to be framed within the visual area that is being recorded and must be comfortable. For this reason, in one of the performances, the height of the seat can be adjusted and it has armrest. For a better durability, and due to the potential location of the system in public places, the seat is metallic.

The background panel (k) has a double function: on one side it obstructs visually either partially or totally what's happening at the back and, on the other side, it offers the transmitter a border. To achieve these goals, the background panel can be of different materials (such as plate, plastic, acrylic, polycarbonate, etc.) Preferably, as shown in Figure.3, it's an acrylic panel fixed to the floor by means of a non-rusting steel base-board (m) . That panel may have different shapes provided that it may accomplish its double function (for example: a square, oval, circular, triangular contour, etc.) and have a surface with different arrangements (flat, concave, convex). It's preferable, as shown in Figure 3, to have a rectangular or square background panel and, in a plant view, it presents a parabolic shape with the concavity oriented to the front. The background panel may have posting supports to join it to an interchangeable decoration in order to modify the transmitter environment. In Figure 3, the background panel (k) has at the top posting or support means for graphic advertising (n) . Additionally, the background panel (k) may have at the top illumination devices to improve the visualization of the graphic advertising and/or enhance the image of the transmitter.

The two isolating acoustic panels (o) , located one on each side of the transmitter's seat, are fixed to the background panel (k), oriented in a parallel way to the front-back axis of each seat (j) which isolate the transmitter (1) from the environmental sound. In a special per- formance of this invention, the isolating acoustic panels (o) are made of MDF wood covered by cloth. However, it's acceptable any other available isolating acoustic material.

In another preferred performance of the system for the capture and recording of image and sound in public places, a start mechanism by the introduction of token or coins is part of the transmission unit and in connected to the computer located in the recording unit. The advantage is that the transmitter needs not to move up to the recording unit to start the system. Evidently, in this way of performance, the recording unit may or may not have its own start mechanism by introducing tokens or coins. The connection between the start mechanism of the transmission unit and the computer of the recording unit may be by cable or wireless. The wireless methods are preferred, and, particularly the connections by infrared beams.

In another performance of the system for the images and sound capture and recording in public places, a mecha- nism to get a recording proof becomes part of the transmission unit and is connected to the computer located in the recording unit. The advantage of it is that the transmitter needs not to move up to the recording unit to get his/her ticket . , •

And in this performance, the start mechanism by the introduction of tokens or coins may be located either in the recording unit or in the transmission unit. The connection between the mechanism issuing a recording proof of the transmission unit and the computer of the recording unit may be by cable or wireless. The wireless method is preferred, and particularly the connections through infrared beams .

The system for the image and sound capture and recording in public places, as described before, may comprise, apart from the recording and transmission units, a promotion unit which consists in a portable support structure which has:

a) one or more TV or computer monitors connected to the power supply unit, located at the top of the support structure. b) One or more compartments for graphic advertising means such as a placard located at the back and being this support for the placard fixed to the support structure of the set or being the support structure the one which is designed for the placard.

c) a catalogs-bearer tray located below the compartment for the graphic advertising media of point (b) , and

d) a deposit for promotional material, composed of a compartment integrated to the main module with a door.

Figure 4 shows a view of the image and sound capture and recording system in public places composed of a recording unit (x), a transmission unit (y) and a promotion unit (z). In the promotion unit (z), it's located at the very top of the set support structure, the TV or computer monitor (q), which, in this particular case, there are 2, oriented one at the back of the other, to get a better visualization from the distance. Below those monitors (q), it's located on each side of the set support structure (p) the compartments for the graphic advertising media like placards (r) . Just below the compartment for the graphic advertising media (r), it's located a catalogs-bearer tray. This tray is positioned at an appropriate height so that the public can reach the promotional material contained therein in a com^¬ fortable way. The ideal distance from the floor is at least 65 cm. Finally, below the catalogs-bearer tray (s), it's located the deposit for promotional material (t) .

In a certain performance of the invention, the TV or computer monitors are 24" flat screen ones.

In another particular way of the invention, the deposit door for the promotional material has a lock to shut it.

As well as the set containing structure of the recording unit, the set support structure of the promotional unit can be made of different materials, such as plastic, acrylic, resins, metal, wood, etc. The preferred way for the invention is an internal structure of metallic outlines (for ex. Aluminium) recovered by a MDF plastic and/or wood shell.
