DISPOSITIVO REDIRECCIONADOR DE IMÁGENES PARA APARATOS ELECTRÓNICOSIMAGE REDIRECTING DEVICE FOR ELECTRONIC DEVICES

CON CÁMARA WITH CAMERA

Sector de la técnica Technical sector

La presente invención está relacionada con la industria dedicada a aparatos electrónicos con cámara, y más concretamente con la industria dedicada a dispositivos para ser empleados en relación con las cámaras de los aparatos electrónicos. The present invention is related to the industry dedicated to electronic devices with cameras, and more specifically to the industry dedicated to devices to be used in relation to the cameras of electronic devices.

Estado de la técnica State of the art

En la actualidad aparatos electrónicos tales como tabletas, denominadas "tablets" en inglés, y teléfonos móviles, incluyen cámaras que permiten tanto sacar fotos como grabar videos. Sin embargo, el uso de las cámaras no se limita a sacar fotos o grabar videos a paisajes o personas dispuesta frente a dichos aparatos electrónicos. Currently electronic devices such as tablets, called "tablets" in English, and mobile phones, include cameras that allow both take pictures and record videos. However, the use of the cameras is not limited to taking photos or recording videos to landscapes or people willing in front of such electronic devices.

Actualmente, mediante las cámaras también se capta una imagen para después ser empleada en aplicaciones denominables de entretenimiento. Estas aplicaciones requieren captar la imagen de acuerdo a una localización angulada, por ejemplo según un ángulo próximo a los 90° con respecto al aparato electrónico de acuerdo con una superficie horizontal de apoyo de los mismos. Es decir, las aplicaciones no se limitan a emplear las imágenes captables únicamente de manera frontal con respecto al aparato electrónico correspondiente. Currently, through the cameras an image is also captured and then used in denominable entertainment applications. These applications require capturing the image according to an angled location, for example at an angle close to 90 ° with respect to the electronic device according to a horizontal support surface thereof. That is, the applications are not limited to using the images that can only be captured frontally with respect to the corresponding electronic device.

Estos requerimientos por parte de las actuales aplicaciones dejan al descubierto limitaciones de las cámaras. Si bien estas limitaciones pueden ser solventadas estando las cámaras y los aparatos electrónicos especialmente configurados para ello, los costes de los aparatos electrónicos se incrementarían substancialmente. These requirements from current applications expose camera limitations. Although these limitations can be solved with the cameras and electronic devices specially configured for this, the costs of the electronic devices would be substantially increased.

Una solución empleable consiste en sustentar una superficie reflectante de forma que reflecta a la cámara la imagen de lo dispuesto en un plano de reposo del aparato electrónico. Sin embargo, esta solución presente graves inconvenientes puesto que frente a desajustes en su posicionamiento con respecto al propio aparato electrónico, derivados por ejemplo por vibraciones, la imagen reflejada a la cámara resulta alterada. Así, la imagen resulta desvirtuada, lo cual resulta altamente indeseado en el uso de las aplicaciones. An employable solution consists in supporting a reflective surface in a way that reflects the image of the disposition in a resting plane of the electronic device to the camera. However, this solution has serious drawbacks, given that there are mismatches in its positioning with respect to the electronic device itself, derived from example by vibrations, the image reflected to the camera is altered. Thus, the image is distorted, which is highly unwanted in the use of applications.

Frente a este inconveniente, se tiende a proveer la superficie reflectante con unos medios de acoplamiento configurados para ser dispuesta de manera removible en el aparato electrónico correspondiente, siendo dichos medios altamente rigidizados a fin de tratar de evitar movimientos o vibraciones de la superficie reflectante con respecto al aparato electrónico en el que se encuentra dispuesta. Faced with this drawback, the reflective surface tends to be provided with coupling means configured to be removably disposed in the corresponding electronic apparatus, said means being highly stiffened in order to try to avoid movements or vibrations of the reflective surface with respect to to the electronic device in which it is arranged.

Esta configuración completamente rígida de los medios de acoplamiento tampoco acaba aportando una solución efectiva puesto que, además de no evitar por completo dichas vibraciones, por un lado reduce significativamente la flexibilidad de ajustarse a los aparatos electrónicos existentes en el mercado, los cuales varían ampliamente en espesor, y por otro lado dañan los aparatos electrónicos por esfuerzos de compresión generados en éstos con el objeto de evitar los citados e indeseados movimientos de las superficies reflectantes. This completely rigid configuration of the coupling means also does not end up providing an effective solution since, in addition to not completely avoiding such vibrations, on the one hand it significantly reduces the flexibility of adjusting to the electronic devices existing in the market, which vary widely in thickness, and on the other hand they damage the electronic devices by compression efforts generated in them in order to avoid the aforementioned and unwanted movements of the reflective surfaces.

A la vista de las descritas desventajas que presentan las soluciones existentes en la actualidad, resulta evidente que es necesaria una solución que permita reflejar la imagen contenida en el plano de apoyo de los aparatos electrónicos de manera efectiva a la cámara a pesar de sufrir vibraciones, sin dañarlos y sin alterar la configuración de los aparatos electrónicos existentes en el mercado. In view of the described disadvantages that present solutions presently present, it is clear that a solution is necessary to reflect the image contained in the support plane of the electronic devices effectively to the camera despite suffering vibrations, without damaging them and without altering the configuration of existing electronic devices in the market.

From In this way, simplicity is also provided, a care in the removable arrangement in electronic devices.

El dispositivo redireccionador de imágenes adicionalmente comprende un prisma de Littrow (8). El prisma de Littrow (8) se denomina también prisma de dispersión o prisma de dispersión Littrow. El prisma de Littrow (8) tiene una primera cara (8.1) dispuesta para entrada y reflexión de una imagen; una segunda cara (8.2) dispuesta para reflexión de la imagen; una tercera cara (8.3) dispuesta para salida de la imagen. La primera cara (8.1) y la segunda cara (8.2) están anguladas entre sí de acuerdo a un ángulo menor preferentemente de entre 25° y 35°, y más preferentemente de 30°. Adicionalmente, la primera cara (8.1) y la tercera cara (8.3) están anguladas entre sí de acuerdo a un ángulo mayor preferentemente de entre 65° y 55°, y más preferentemente de 60°. Asimismo, el prisma de Littrow (8) adicionalmente tiene dos caras laterales (8.4), con forma triangular, cada una de las cuales uniendo la primera cara (8.1), la segunda cara (8.2) y la tercera cara (8.3). The image redirector device additionally comprises a Littrow prism (8). The Littrow prism (8) is also called the dispersion prism or Littrow dispersion prism. The prism of Littrow (8) has a first face (8.1) arranged for input and reflection of an image; a second face (8.2) arranged for reflection of the image; a third face (8.3) arranged for image output. The first face (8.1) and the second face (8.2) are angled together according to a smaller angle preferably between 25 ° and 35 °, and more preferably 30 °. Additionally, the first face (8.1) and the third face (8.3) are angled together according to a greater angle preferably between 65 ° and 55 °, and more preferably 60 °. Likewise, the Littrow prism (8) additionally has two lateral faces (8.4), triangular in shape, each of which joining the first face (8.1), the second face (8.2) and the third face (8.3).

El prisma de Littrow (8) es dispuesto encajado en la carcasa (1). La carcasa (1) incluye unos nervios (9) para establecer contacto con las caras laterales (8.4) en disposición de encaje del prisma de Littrow (8) en la carcasa (1). The prism of Littrow (8) is arranged embedded in the housing (1). The housing (1) includes ribs (9) to establish contact with the lateral faces (8.4) in arrangement of the Littrow prism (8) in the housing (1).

El dispositivo redireccionador de imágenes adicionalmente comprende un espejo (10). El espejo (10) tiene una cara reflectante la cual queda dispuesta enfrentada con la segunda cara (8.2) cuando el prisma de Littrow (8) y el espejo (10) son conjuntamente dispuestos en contacto entre sí en la disposición de uso del dispositivo redireccionador de imágenes. Esta descrita disposición del espejo (10) mejora notablemente la reflexión de la segunda cara (8.2) al impedir el paso de luz a través de la misma y reflejar la imagen que recibe. The image redirector additionally comprises a mirror (10). The mirror (10) has a reflective face which is arranged facing the second face (8.2) when the Littrow prism (8) and the mirror (10) are jointly arranged in contact with each other in the use arrangement of the redirecting device of pictures. This described arrangement of the mirror (10) significantly improves the reflection of the second face (8.2) by preventing the passage of light through it and reflecting the image it receives.

El panel (7) incluye unos brazos (1 1) para, de acuerdo con la disposición de uso, ejercer una presión sobre el espejo (10), estando el espejo (10) apoyado contra el prisma de Littrow (8) y el prisma de Littrow (8) retenido en la parte interna de la carcasa (1) por el marco (1.3). The panel (7) includes arms (1 1) for, in accordance with the use arrangement, to exert pressure on the mirror (10), the mirror (10) being supported against the Littrow prism (8) and the prism Littrow (8) retained on the inside of the housing (1) by the frame (1.3).

Con el objeto de optimizar la transmisión y reflexión de las imágenes mediante el prisma de Littrow (8), la carcasa (1) es opaca y cubre las caras laterales (8.4) para evitar que a través de dichas caras laterales (8.4) incida luz con un efecto negativo, tal como perdida de nitidez y/o creación de aberraciones cromáticas, en la calidad de la imagen a ser transmitida y redireccionada intencionadamente a través del prisma de Littrow (8). In order to optimize the transmission and reflection of the images by means of the Littrow prism (8), the housing (1) is opaque and covers the lateral faces (8.4) to prevent light from entering through said lateral faces (8.4) with a negative effect, such as loss of sharpness and / or creation of chromatic aberrations, in the quality of the image to be transmitted and intentionally redirected through the prism of Littrow (8).

Asimismo, la ventanilla (5) evita el paso de luz, concretamente de manera lateral, a la cámara del aparato electrónico a ser dispuesta en correspondencia con dicha ventanilla (5). De esta manera, se optimiza la calidad de la imagen captable mediante la cámara transmitida y redireccionada intencionadamente a través del prisma de Littrow (8). Likewise, the window (5) prevents the passage of light, specifically laterally, to the chamber of the electronic device to be arranged in correspondence with said window (5). In this way, the quality of the captivable image is optimized by means of the camera transmitted and intentionally redirected through the Littrow prism (8).

El dispositivo redireccionador de imágenes es colocable en el aparato electrónico correspondiente mediante encaje, siendo la extensión (6) elásticamente deformable para ser dispuesta adaptándose al espesor del aparato electrónico. Esta disposición del dispositivo redireccionador de imágenes se da de forma que la cámara del aparato electrónico queda enfrentada a la tercera cara (8.3). El dispositivo redireccionador de imágenes incluye un elemento elástico (12), tal como una goma, unido a la extensión (6), y más concretamente al cuarto tramo (6.4) de la extensión (6), para apoyo contra el aparato electrónico a ser dispuesto encajado entre el cuarto tramo (6.4) y la ventanilla (5). De acuerdo con esto, es captable la imagen localizada en un plano angulado, perpendicular o entre 70° y 110°, al plano de contención del aparato electrónico, correspondiéndose dicho plano angulado con la superficie de reposo del aparato electrónico por un canto del mismo. La imagen captada por la cámara inicialmente incide por la primera cara (8.1) al interior del prisma de Littrow (8), esta imagen es transmitida hasta la segunda cara (8.2). En esta segunda cara (8.2) la imagen es reflejada, siendo esta reflexión altamente efectiva por la contribución efectuada por el espejo (10). Posteriormente, la imagen reflejada por la segunda cara (8.2) y el espejo (10) alcanza de nuevo la primera cara (8.1), siendo esta vez la imagen reflejada en vez de pasar a través de dicha primera cara (8.1). La imagen reflejada en la primera cara (8.1) es dirigida esta vez a la tercera cara (8.3). El ángulo de incidencia de la imagen al alcanzar la tercera cara (8.3) es tal que la imagen pasa a través de la misma en vez de resultar reflejada para alcanzar la cámara del aparato electrónico correspondiente. The image redirector device can be placed in the corresponding electronic device by means of fitting, the extension (6) being elastically deformable to be arranged adapting to the thickness of the electronic device. This arrangement of the image redirecting device occurs in such a way that the camera of the electronic device faces the third face (8.3). The image redirecting device includes an elastic element (12), such as a rubber, attached to the extension (6), and more specifically to the fourth section (6.4) of the extension (6), for support against the electronic device to be arranged embedded between the fourth section (6.4) and the window (5). Accordingly, the image located in an angled plane, perpendicular or between 70 ° and 110 °, can be captured to the containment plane of the electronic device, said angular plane corresponding to the resting surface of the electronic device by a song edge thereof. The image captured by the camera initially strikes the first side (8.1) inside the Littrow prism (8), this image is transmitted to the second side (8.2). In this second face (8.2) the image is reflected, this reflection being highly effective due to the contribution made by the mirror (10). Subsequently, the image reflected by the second face (8.2) and the mirror (10) again reaches the first face (8.1), this time the image being reflected instead of passing through said first face (8.1). The image reflected on the first face (8.1) is directed this time to the third face (8.3). The angle of incidence of the image upon reaching the third face (8.3) is such that the image passes through it instead of being reflected to reach the corresponding electronic device chamber.

La reflexión o el paso a través de la primera, segunda y tercera cara (8.1 , 8.2, 8.3) del prisma de Littrow (8) es debido a que cuanto más perpendicular es la dirección de la imagen en su transmisión mayor grado de paso a través de la cara (8.1 , 8.2, 8.3) correspondiente y menor grado de reflexión; y por el contrario, cuanto más paralelamente incide la imagen contra una de las caras (8.1 , 8.2, 8.3), menor es el grado de paso y mayor el de reflexión. The reflection or passage through the first, second and third faces (8.1, 8.2, 8.3) of the Littrow prism (8) is because the more perpendicular is the direction of the image in its transmission greater degree of passage through the corresponding face (8.1, 8.2, 8.3) and lower degree of reflection; and on the contrary, the more parallel the image strikes one of the faces (8.1, 8.2, 8.3), the lower the degree of passage and the greater the reflection.

El empleo del prisma de Littrow (8) permite corregir movimientos de cabeceo del dispositivo redireccionador de imágenes con respecto al aparato electrónico. Esta corrección se da mediante la doble reflexión que realiza en su interior, primero con la segunda cara (8.2) junto al espejo (10) y después con la primera cara (8.1). Las angulaciones de las caras (8.1 , 8.2, 8.3) entre sí están definidas con esta finalidad también. De esta manera, ante cabeceos del dispositivo redireccionador de imágenes en el aparato electrónico la imagen percibida o captada por la cámara resulta inalterada. The use of the prism of Littrow (8) allows to correct movements of head of the device redirector of images with respect to the electronic device. This correction is made through the double reflection inside, first with the second face (8.2) next to the mirror (10) and then with the first face (8.1). The angulations of the faces (8.1, 8.2, 8.3) with each other are defined for this purpose as well. In this way, before headings of the redirecting device of images in the electronic device the image perceived or captured by the camera is unaltered.
