In the device and corresponding process for the lifelike, three-dimensional representation of speaking people, the face of a doll (2) is used as a projection screen. By means of a sound and image projection device (26), a film taken of the person concerned is projected on parts of the face of the doll (20) from inside and/or outside. At the same time an audio signal recorded by the same person is emitted in synchronism therewith.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur lebensnahen Darstellung von sprechenden Personen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for the realistic representation of speaking people according to the preamble of claim 1.

Derartige Vorrichtungen sind aus der US-A-3,053,144, der US-A-1,653,180 und der US-A- 3,973,840 bekannt. Bei diesen vorbekannten Vorrichtungen ist die Aufstellung am Einsatzort nicht ohne Spezialkenntnisse möglich.Such devices are known from US-A-3,053,144, US-A-1,653,180 and US-A-3,973,840. With these previously known devices, installation on site is not possible without special knowledge.

Hier setzt nun die Erfindung ein. Sie hat es sich zur Aufgabe gemacht, möglichst lebensechte Darstellungen von Personen, vorzugsweise bekannten, zur Zeit noch lebenden Persönlichkeiten, anzugeben. Die dabei eingesetzten Vorrichtungen und Verfahren sollen preisgünstiger zu erstellen und aufzubauen sein als animierte Puppen aus Freizeitparks und sollen einen möglichst täuschend echten Eindruck für einen unvoreingenommenen Betrachter bewirken. Dieser soll spontan den Eindruck haben, nicht einem Abbild der Person, sondern der Person selbst gegenüber zu stehen. Die Erfindung bezweckt somit eine möglichst täuschend mit der Wirklichkeit ähnliche Vorrichtung für die Darstellung einer Person.This is where the invention begins. It has set itself the task of providing life-like representations of people, preferably known, still living personalities. The devices and methods used should be cheaper to build and assemble than animated dolls from amusement parks and should give the most deceptive impression possible for an unbiased observer. This should spontaneously have the impression that it is not an image of the person, but of the person himself. The invention thus aims at a device for the representation of a person that is as deceptively as possible similar to reality.

Gelöst wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1.This object is achieved by a device with the features of patent claim 1.

Erfindungsgemäß wird somit eine lebensgroße, mit der darzustellenden Person möglichst identische Puppe erstellt, beispielsweise von der Qualität einer Schaufensterpuppe. Diese wird auch so gekleidet, wie die darzustellende Person üblicherweise gekleidet ist. Die Puppe wird an einem bevorzugten Darstellungsort, beispielsweise im Eingang eines Verkaufsbereiches, in einer Ausstellung, in einem Schaufenster oder dergleichen aufgestellt und so gut beleuchtet, daß sie das Auge des Betrachters auf sich zieht. Die Projektionsvorrichtung für Licht und Ton ist möglichst versteckt, für das Auge des Betrachters nicht sichtbar angeordnet. Sie befindet sich im Fuß der Puppe, oder sie ist unterhalb dieser angeordnet. Auch das Lichtbündel, das bei der Projektion von außen auf das Gesicht der Puppe eingesetzt wird, wird über den Spiegel so geführt, daß es möglichst - zumindest anfänglich - für einen unvoreingenommenen Betrachter nicht ins Auge fällt.According to the invention, a life-size doll that is as identical as possible to the person to be represented is thus created, for example of the quality of a mannequin. This is also dressed in the way the person to be depicted is usually dressed. The doll is placed at a preferred location, for example in the entrance of a sales area, in an exhibition, in a shop window or the like, and is illuminated so well that it draws the eye of the beholder. The projection device for light and sound is hidden as far as possible, not visible to the eye of the beholder. It is located in the foot of the doll or it is arranged below it. Even the beam of light, that is used for the projection from the outside onto the face of the puppet is guided over the mirror in such a way that it is as obvious as possible - at least initially - for an impartial observer.

Die Puppen nach der Erfindung benötigen keine sich mechanisch bewegenden Teile. Die Projektion eines Filmes des sich bewegenden Gesichts erfolgt auf das in Ruhe befindliche Gesicht der Puppe. Anders ausgedrückt bildet das Gesicht der Puppe den Projektionsschirm für den Film, der von der Person während des Sprechens aufgenommen wurde. Unter Sprechen wird in der vorliegenden Anmeldung dabei auch ein Singen, Pfeifen oder dergleichen, also jede lautliche Äußerung eines Menschen, verstanden.The dolls according to the invention do not require any mechanically moving parts. A film of the moving face is projected onto the resting face of the doll. In other words, the face of the doll forms the projection screen for the film that was recorded by the person while speaking. In the present application, speaking is also understood to mean singing, whistling or the like, that is to say every sound uttered by a person.

Das Gesicht der Puppe ist von sich aus lebensnah nachgebildet, die Puppe hat also vorzugsweise selbst Augen und einen Mund, in einer geänderten Ausführung können diese aber auch nur projiziert werden. Die Projektion des Films erfolgt nun dergestalt, daß das Lichtbild exakt auf das vorhandene Gesicht paßt und die Änderungen im Gesicht hervorruft, die beim Sprechen auftreten. Dabei werden Bewegungsfalten auf das Gesicht projiziert, es findet eine Bewegung der Augen statt, die Lippen bewegen sich im Rhythmus der Sprache.The face of the doll is naturally reproduced, so the doll preferably has eyes and a mouth, but in a modified version these can only be projected. The film is now projected in such a way that the light image fits exactly on the existing face and causes the changes in the face that occur when speaking. Wrinkles of movement are projected onto the face, the eyes move, the lips move in the rhythm of the language.

Die Erfindung ist also insbesondere und vorzugsweise dazu geeignet, bekannte Persönlichkeiten, die derzeit, zumindest zum Zeitpunkt der Aufnahme des Films, noch leben, täuschend ähnlich wiederzugeben. Die Puppe wird der bekannten Persönlichkeit möglichst entsprechend nachgebildet. Weiterhin wird von der bekannten Persönlichkeit mindestens ein Film des Gesichts bei einem Sprechvorgang aufgenommen. Diese Aufnahme erfolgt vorzugsweise auf gleicher Achse wie die spätere Wiedergabe. Gleichzeitig wird der Ton aufgezeichnet. Puppe und Tonfilm können beliebig oft hergestellt werden. Eine Installation ist im Vergleich zu einer mechanisch bewegten Puppe wesentlich preisgünstiger.The invention is therefore particularly and preferably suitable for portraying well-known personalities who are still alive at least at the time the film was recorded. The doll is modeled according to the known personality as possible. Furthermore, the known personality records at least one film of the face during a speaking process. This recording is preferably made on the same axis as the later playback. At the same time, the sound is recorded. Doll and sound film can be made as often as you like. Installation is much cheaper than a mechanically moved doll.

Derartige Puppen können in verschiedensten Bereichen eingesetzt werden, beispielsweise von Gestaltung von Messeständen, im Lehrmittelbereich, im Theater und Film. Beim Theater können beispielsweise Veränderbarkeit von Makeup und Erscheinungsbild eines Künstlers durch Transformation, d. h. Wechsel verschiedener Makeups erreicht werden.Such dolls can be used in a wide variety of areas, for example designing exhibition stands, teaching aids, theater and film. In theater, for example, the make-up and appearance of an artist can be changed by transforming, ie changing, different make-ups.

Weiterhin ist die Erfindung günstig einsetzbar im medizinischen Bereich als Lehrmittel.Furthermore, the invention can be used favorably in the medical field as a teaching aid.

Ein weiterer bevorzugter Bereich für die Erfindung ist im Bereich von Freizeitparks zu sehen, hier beispielsweise in Geisterbahnen.Another preferred area for the invention can be seen in the area of amusement parks, here for example in ghost trains.

Es können auch Phantasiefiguren als Puppe verwendet werden.Fantasy figures can also be used as a doll.

In vorzugsweiser Weiterbildung werden nicht nur Teilbereiche des Gesichts, beispielsweise Mund oder Augen, sondern wird eine Vollprojektion auf das ganze Gesicht durchgeführt. Dadurch treten Unterschiede zwischen Bildbereichen der Projektion und projektionsfreien Zonen des Gesichts weniger deutlich hervor.In preferred further training, not only partial areas of the face, for example mouth or eyes, but a full projection on the entire face is carried out. As a result, differences between image areas of the projection and projection-free zones of the face become less clear.

Die erfindungsgemäße Vorrichtung ist transportabel und variabel. Sie kann rasch am jeweiligen Einsatzort aufgestellt werden, ohne dap hierfür Spezialkenntnisse notwendig sind. Sie kann im Sinne eines Baukastens aus einzelnen Komponenten, beispielsweise den optischen Komponenten, der Komponente Puppe usw. aufgebaut werden. Dabei ist es vorteilhaft, bei den Puppen den Kopf austauschbar zu machen, um durch Aufsetzen unterschiedlicher Köpfe auf einen Rumpf mit Gliedmaßen verschiedene Personen darstellen zu können.The device according to the invention is portable and variable. It can be quickly set up at the respective site, without special knowledge being required. In the sense of a modular system, it can be built up from individual components, for example the optical components, the doll component, etc. It is advantageous to make the head of the dolls interchangeable so that different people can be represented by placing different heads on a trunk with limbs.

Ein motorischer Antrieb der Glieder der Puppe oder des Körpers ist zunächst nicht vorgesehen, in einer vorteilhaften Weiterbildung können aber die Körperteile motorisch angetrieben sein, um auf diese Weise den Täuschungseffekt noch zu verbessern.A motor drive of the limbs of the doll or of the body is initially not provided, but in an advantageous further development the body parts can be motor-driven in order to improve the deception effect in this way.

Die Projektion des Lichtsignals von außen auf das Gesicht der Puppe erfolgt mit einer Tiefenschärfe, die ausreicht, um alle Bereiche des Gesichts scharf auf dem als Projektionsschirm wirkenden Gesicht der Puppe abzubilden.The projection of the light signal from the outside onto the face The doll is made with a depth of field that is sufficient to sharply image all areas of the face on the doll's face, which acts as a projection screen.

Bei der Projektion können Verzerrungen auftreten, beispielsweise durch den Umlenkspiegel. Diese lassen sich dadurch ausgleichen, daß der Kamerastandort (bei der Aufnahme) weitgehend dem Projektionsstandort bei der Wiedergabe bzw. dem Standort des letzten Umlenkspiegels entspricht. In anderer Ausführung können aber auch gezielt im Film Vorverzerrungen, beispielsweise elektronische Vorverzerrungen, eingebracht werden, durch die der Wölbung der Projektionsfläche Rechnung getragen wird. Schließlich sind auch optische und mechanische Verzerrungen durch Einsatz von Spezialobjektiven möglich.Distortion can occur during projection, for example due to the deflection mirror. These can be compensated for by the fact that the camera location (when recording) largely corresponds to the projection location during playback or the location of the last deflecting mirror. In another embodiment, however, predistortions, for example electronic predistortions, can also be introduced specifically in the film, by means of which the curvature of the projection surface is taken into account. Finally, optical and mechanical distortions are also possible through the use of special lenses.

Bei der Lichtprojektion von außen auf das Gesicht der Puppe ist das Gesicht der Puppe entweder lichtundurchlässig oder zumindest bereichsweise transparent, vorzugsweise milchig-transparent ausgebildet. Das zur Projektion verwendete Lichtbündel kommt vom Spiegel her zumindest teilweise aus der selben Richtung, aus der ein Betrachter sich üblicherweise bei der Erstbegegnung der Puppe nähert. Der Betrachter sieht aber nicht unmittelbar die Projektionsvorrichtung, die im Fuß oder unterhalb der Puppe versteckt ist. Hierzu hält vorzugsweise die Puppe den Spiegel in der Hand, über den die Projektion auf das Gesicht gelenkt wird, oder es ist ein entsprechender Spiegel an irgendeiner versteckten Stelle vorgesehen.When the light is projected onto the face of the doll from the outside, the face of the doll is either opaque or at least partially transparent, preferably milky transparent. The light beam used for the projection comes at least partially from the mirror in the same direction from which a viewer usually approaches the puppet at the first encounter. However, the viewer does not immediately see the projection device which is hidden in the foot or below the doll. For this purpose, the doll preferably holds the mirror in his hand over which the projection is directed onto the face, or a corresponding mirror is provided at some hidden location.

Als besonders vorteilhaft hat es sich erwiesen, die Projektionsfläche des Gesichts mit speziellen Effektkörpern zu versehen. Hierzu gehören aktiv leuchtende Pigmente, beispielsweise Fluoreszenzfarbstoffe, die bei geeigneter Projektion sichtbares Licht abgeben. Weiterhin durch Temperatur in ihrer Farbwirkung veränderbare Farbstoffe usw. Als sehr vorteilhaft hat es sich auch erwiesen, die Oberfläche der Projektionsbereiche, des Gesichts, mit einer polarisierenden Projektionsoberfläche zu versehen. Dadurch wird zwar das polarisierte Projektorlicht reflektiert, störendes Fremdlicht wird jedoch weitestgehend zurückgehalten.It has proven to be particularly advantageous to provide the projection surface of the face with special effect bodies. These include actively glowing pigments, for example fluorescent dyes, which emit visible light when they are appropriately projected. Furthermore, dyes that can be changed by temperature, etc. It has also proven to be very advantageous to provide the surface of the projection areas, of the face, with a polarizing projection surface. Although this reflects the polarized projector light, disturbing extraneous light is largely retained.

Puppen, die nicht alle Merkmale des Erfindung darstellen, werden im folgenden beschrieben. Die Beschreibung erfolgt unter Bezugnahme auf die Zeichnung und ist als nicht einschränkend zu verstehen. In der Zeichnung zeigen:

Von einer vollständigen, lebensnah darstellten, dreidimensionalen Puppe 20 ist in Fig. 1 lediglich der Oberteil des Rumpfes 22 und der Kopf 24 gezeigt. Die Puppe ist nach den Originalmaßen im Maßstab 1 : 1 einer allgemeiner bekannten Persönlichkeit, beispielsweise aus dem Unterhaltungs- oder Sportbereich, gefertigt. Kopf 24 und Rumpf 22 sind innen hohl. Im Rumpf 22 ist eine Projektionsvorrichtung 26 für Ton und Bild angeordnet. Ihr Tonausgang ist mit einem Lautsprecher 28 verbunden, der in der hier gezeigten Darstellung sich im Brustbereich befindet und nach vorn abstrahlt. Er kann auch im Kopf 24 angeordnet sein. Das Ausgangslicht der Projektionsvorrichtung 26 fällt auf einen Spiegel, der sich im Bereich des Hinterkopfes befindet und so angeordnet ist, daß das Ausgangslicht der Projektionsvorrichtung 26 von innen auf den dünnwandig ausgebildeten Gesichtsbereich des Kopfes 24 fällt. Dort findet auch die Abbildung statt. Der Gesichtsbereich des Kopfes 24 ist aus milchigem, transparentem Kunststoff erstellt. Die Augen sind transparent außen aufgemalt, ebenso die Mundpartie und weitere Einzelheiten des Gesichtes. Die Abbildung eines von der dargestellten Persönlichkeit aufgenommenen Filmes erfolgt nun derart, daß die projizierten Gesichtsbereiche, insbesondere Augen, Backen und Mund, mit den entsprechenden Gesichtsbereichen der Puppe 20 vollständig übereinstimmen und durch die optische Projektion der Eindruck hervorgerufen wird, als bewege sich das Gesicht der Puppe 20, also als könne der Kopf sprechen.Of a complete, three-dimensional doll 20 that is depicted in real life, only the upper part of the torso 22 and the head 24 are shown in FIG. 1. The doll is made according to the original dimensions on a scale of 1: 1 by a generally known personality, for example from the entertainment or sports sector. Head 24 and body 22 are hollow on the inside. A projection device 26 for sound and image is arranged in the fuselage 22. Its sound output is connected to a loudspeaker 28 which, in the illustration shown here, is located in the chest area and radiates to the front. It can also be arranged in the head 24. The output light of the projection device 26 falls on a mirror which is located in the area of the back of the head and is arranged such that the output light of the projection device 26 falls from the inside onto the thin-walled face area of the head 24. The mapping also takes place there. The face area of the head 24 is made of milky, transparent plastic. The eyes are painted transparently on the outside, as is the mouth area and other details of the face. The depiction of a film recorded by the person portrayed is now carried out in such a way that the projected facial areas, in particular eyes, cheeks and mouth, completely match the corresponding facial areas of the doll 20 and the optical projection creates the impression that the face of the puppet is moving Doll 20, so as if the head could speak.

Die Puppe selbst ist so hergestellt, daß das Gesicht sich in einer Normalstellung während des Sprechens befindet. Die Lippen sind leicht geöffnet, ebenso die Augen, die Pupillen befinden sich in einer Normalstellung. Auslenkungen aus dieser Normalstellung im Bereich der Lippen, der Faltenbildung im Bereich der Backen und der Augen werden nun durch optische Projektion bewirkt. Hinzu kommt das synchrone Tonsignal, das über den Lautsprecher 28 abgestrahlt wird. Es ist vorzugsweise von der Person selbst gesprochen, kann aber auch von einem Synchronsprecher stammen.The doll itself is made so that the face is in a normal position while speaking. The lips are slightly open, as are the eyes, the pupils are in a normal position. Deflections from this normal position in the area of the lips, the formation of wrinkles in the area of the cheeks and the eyes are now brought about by optical projection. In addition, there is the synchronous audio signal which is emitted via the loudspeaker 28. It is preferably spoken by the person himself, but can also come from a voice actor.

Die Projektionsvorrichtung 26 ist in Videotechnik ausgeführt, ein Videoband (nicht dargestellt) wird in ein optisches Bild umgesetzt und dieses mittels einer Beleuchtungsquelle auf die Innenfläche des dünnwandigen Gesichts des Kopfes projiziert. Der Kopf 24 ist in seinen sonstigen Bereichen nicht durchlässig, um zu vermeiden, daß Streulicht unerwünschte Lichteffekte hervorruft. So kann beispielsweise auch der Bereich der Nase weniger transparent, vorzugsweise nicht transparent ausgebildet sein, um hier unerwünschte Lichteffekte zu vermeiden. Derartige, nicht transparente Gesichtsbereiche gehen fein abgestuft in die transparenten Gesichtsbereiche über, so daß keine Lichtsprünge entstehen. Das Ausgangsstrahlenbündel der Projektionsvorrichtung 26 ist dargestellt. Die Puppe 20 wird auch von außen angestrahlt. Die Außenbeleuchtung des Gesichts erfolgt dabei so, daß die bekannte, von innen erfolgende Abbildung nicht als Lichtquelle wirkt.The projection device 26 is implemented in video technology, a video tape (not shown) is converted into an optical image and this is projected onto the inner surface of the thin-walled face of the head by means of an illumination source. The head 24 is not permeable in its other areas, in order to avoid that stray light causes undesired light effects. For example, the area of the nose can also be made less transparent, preferably not transparent, in order to avoid undesirable light effects here. Such non-transparent facial areas merge into the transparent facial areas so that no light jumps occur. The output beam of the projection device 26 is shown. The doll 20 is also illuminated from the outside. The external illumination of the face takes place in such a way that the well-known, internal image does not act as a light source.

Fig. 2 zeigt eine Projektion von außen auf das Gesicht einer Puppe 20. Hier laufen im wesentlichen dieselben Vorgänge ab, wie sie für die erste Puppe beschrieben wurden. In diesem Fall erfolgt jedoch die optische Projektion durch die Projektionsvorrichtung 26 auf die Außenfläche des Gesichts, wobei auch wiederum nur Teilbereiche ausgenutzt werden. Die Außenfläche des Gesichts ist entsprechend als Projektionsschirm ausgeführt, hat also für sichtbares Licht ein ausreichendes Reflexionsvermögen.2 shows a projection from the outside onto the face of a doll 20. Here, essentially the same processes take place as those described for the first doll. In this case, however, the optical projection is carried out by the projection device 26 onto the outer surface of the face, again only partial areas being used. The outer surface of the face is designed as a projection screen, so it has sufficient reflectivity for visible light.

Bes der Puppe nach Fig. 2 erfolgt die Projektion von schräg unten. Um verzerrungsbedingte Abweichungen zu vermeiden, kann im Lichtweg der Projektion, vorzugsweise am Ausgang der Projektionsvorrichtung 26, eine verzerrende Optik angeordnet sein, die die aufnahme- und projektionsbedingten Verzerrungen ausgleicht.Bes the puppet of FIG. 2, the projection takes place obliquely from below. In order to avoid deviations due to distortion, a distorting optical system can be arranged in the light path of the projection, preferably at the output of the projection device 26, which compensates for the distortions caused by the recording and the projection.

Die beiden bekannten Projektionsverfahren nach Fig. 1 und Fig. 2 können auch kombiniert werden. Die Projektionsvorrichtung 26 kann mit einem Rechner verbunden sein, der Eingangsbefehle durch ein Mikrofon, das an eine entsprechende Elektronikkarte angeschlossen ist, erhält. Auf diese Weise ist eine Kommunikation in begrenztem Umfang mit der Puppe möglich.The two known projection methods according to FIGS. 1 and 2 can also be combined. The projection device 26 can be connected to a computer that receives input commands from a microphone that is connected to a corresponding electronic card. In this way, communication with the doll is possible to a limited extent.

In einer Weiterbildung können bei beiden Projektionsarten (innen und/oder außen) Pigmente in den projizierten Bereichen des Gesichts angeordnet sein, die UV-Licht in farbiges, sichtbares Licht umsetzen, derartige Pigmente mit Weißlichtausstrahlung sind beispielsweise als sogenannte Weißmacher bekannt. Die optische Anregung erfolgt dann durch UV-Licht, das den Vorteil hat, nicht für das menschliche Auge sichtbar zu sein. Das UV-Licht regt die Pigmente an, in der ausgewählten Farbe, beispielsweise rot für Lippen, zu strahlen, und zwar an den Stellen, die jeweils belichtet werden.In a further development, with both types of projection (inside and / or outside) pigments can be arranged in the projected areas of the face, which convert UV light into colored, visible light, such pigments with white light radiation are known, for example, as so-called whiteners. The optical excitation is then carried out by UV light, which has the advantage of not being visible to the human eye. The UV light stimulates the pigments to radiate in the selected color, for example red for lips, at the locations that are exposed in each case.

Die Puppe kann größer und/oder kleiner als das Original sein, ein 1:1 Verhältnis wird allerdings angestrebt.The doll can be larger and / or smaller than the original, but a 1: 1 ratio is desirable.

Unter Film wird jeder mögliche Aufzeichnungsträger für optische Informationen verstanden, z. B. Videoband, photographischer Film.Film is understood to mean every possible record carrier for optical information, e.g. B. videotape, photographic film.
