Description

The invention relates to a mobile phone that is equipped with a digital camera, wherein the image sensor and its optical accompanying elements, within the mobile phone, are electromagnetically driven movable and allow shooting from both the back and front of the mobile phone with only one camera.

The digital camera is mounted in a compact ball-shaped housing and placed in a statically mounted in the mobile phone chamber, which is designed as a ball socket / hollow sphere. The ball housing is able to rotate in almost any direction within the mobile phone controlled quickly and thus also to detect fast moving targets, without the need to move the entire case of the mobile phone in which the digital camera is installed , The invention finds application in mobile phones of all kinds, among others in so-called smartphones. The system is capable of moving or rotating the digital camera sensor and its optics, controlled in any direction. Not the mobile phone is being moved or rotated, just the camera (complete with the image sensor and its optics) inside the mobile phone, almost like a human eye.

Almost every mobile phone / smartphone today has a built-in digital camera, usually even two. Two digital cameras are necessary to take pictures of one's surroundings or make videos, and with the other digital camera to make a video conversation via providers offering such services (eg Facebook, Skype, Tanga or Viber, X8, Aquila, etc.). to enable. Because the installation of a digital camera is complex and also because the parts are not very cheap, usually a weaker, inferior front camera for video conversations and self-portraits (so-called selfies) and a better rear camera for image motif or video recordings built. The installation of two digital cameras brings with it even more disadvantages. The space in a smartphone is getting pretty tight for more extensions or technical news. As a rule, most of the space in a smartphone occupies the battery. But the digital cameras and their control are not completely negligible. The installation of a weaker, inferior front camera has other disadvantages. The transmitted video quality via video chat programs is pretty bad on the front camera. While the rear camera can usually take good photos or videos, the front camera can usually take inferior images. With the internet getting faster and faster nowadays, it is in the interest of the user to transfer high quality images or videos, even those made with the front camera. In addition, many people photograph themselves (so-called selfies), a good image quality of the front camera is desirable. For the film / video or image recording, a mobile phone uses an image sensor, which also determines the image resolution. Due to the small dimensions of the optical lens as well as very small sensors, the image acquisition is particularly susceptible to image noise. Even in good lighting conditions, only moderately high-quality images can be generated, compared to conventional digital cameras. It is also clear that in such extremely small image sensors and mini lenses only little light from the environment, or image motif arrives and the lack of light information is compensated by electrical paths. In addition, the sensor micro-components are arranged in a very small space, resulting in field interactions and in the data-signal transfer interference, so no "clean transport" can be guaranteed, resulting in image noise. Only when organic photo sensor technology on the rise, then the pictures are largely better.

The incorporation of two digital cameras in a smartphone requires not only the incorporation of two camera image sensors, but also the optical accompanying elements included in an image-taking optical system, such as the optical lenses, image correction elements, image stabilizers, and a controller to. The software must be able to control the two digital cameras separately, which also makes the operation of a smartphone more or less complicated.

This invention, incorporated in a smartphone (mobile phone with PC features), virtually completely replaces the second digital camera because it is electromagnetically rotatable and can take pictures or record video from both the back and the front. Thus, manufacturers can install a high quality camera instead of two inferior at similar cost.

There are numerous drive systems that are suitable for moving a digital camera. Mostly electric motors (usually stepper motors) and often also small gears are used, which can swing the digital camera back and forth. However, the electric motors and transmissions are associated with some disadvantages. These are not infinitely small in size, carry corresponding weight, may be susceptible to interference (eg, dust or moisture), are not absolutely silent, and are not super fast moving when a quick turn of the digital camera is to be achieved , In addition, as an image stabilizer These systems are absolutely unsuitable anyway because the reaction rate is very low.

The registration GB 2439346 describes a suspension (gimbal) for a ball, which takes place without mechanical contact, purely electromagnetic. There, a ball is held in a solenoid cage, which can then be rotated. In the ball, a digital camera can be installed. Both the rotatable body and the stator shell are here equipped with a large number of electromagnetic coils that need to be powered. Due to the interactivity between the fields of the coils, a rotational movement is generated. The digital camera image sensor and electromagnets are coupled to electrical leads, which in turn are coupled to the stator, resulting in susceptibility to movement of the digital camera and electromagnets. This arrangement is too complicated and economically uninteresting for small devices, such. B. mobile phones. To turn a ball, numerous methods are described.

The registration JP 080272446 describes a device used to move figures on a sphere. The movement can take place in any direction, within physical constraints or fixed parameters.

The application US5413010 describes an electric motor having a spherical rotor.

The application US5280225 describes an apparatus which is designed as a drive system for a spherical body. Here, a sphere is rotated in several axes in the principle of a stepper motor. Rather, this method is used in robotics.

Application U.S. Pat. Pat. 3178600 indicates a structure with spherically arranged coils, allowing rotation of a body on an axis.

Application U.S. Pat. Pat. No. 3260475 shows a special electric motor whose rotor is spherically built and designed for spacecraft. The resulting torque can be deployed in different directions, thus driving in different directions, without special steering devices or gear possible.

In all of these applications, where a bullet is rotated, the systems described therein are quite complicated, not easily scalable and also relatively vulnerable.

Creating a rotating magnetic field is no longer an art nowadays. Rotary-field electric motors have been around for more than a century.

It describes digital camera systems for smartphones, even those that are rotatable, but almost all are operated mechanically. Several smart phone manufacturers have designed smartphones that have a rotatable digital camera that can be mechanically turned by hand, making it possible to take pictures from behind or front images. Such digital cameras were previously used in some laptops, such. B. older series from ASUS (model ASUS W5000). The digital camera here is mounted on a rotatable frame and is rotated by hand backwards or forwards. This digital camera can only be rotated on one axis. You could theoretically also design a multi-directional digital camera that would be mounted in a gimbal. An electrically rotatable digital camera in the conventional sense for notebooks but in the case associated with several problems: z. As the conventional drive (usually via stepper motors and gearbox) would be too crude, vulnerable and would ruin the aesthetics of the mobile phone.

A type of webcam (IP webcam), which is already on the market, can move electrically, but is powered by electric motors and a small gear. Such a principle is also used. used numerous models of surveillance cameras. The motion reaction rate is not particularly high. There are similar principles that would theoretically be transferable even on a mobile phone, laptop, tablet PC, and so on.

There are known methods of slightly swiveling an image sensor into a digital camera electromagnetically in it, slightly shifting the field of view. The optical elements remain static. Image stabilization is done with such methods, but the field of view change is very small, so no great effects can be expected. In addition, physical limits are set here: the further the image sensor moves, the more distorted the image becomes, because the sensor moves on the field of view or focus point of the incident light rays. The optical elements do not follow the sensor movement. Similarly, a method works where only one of the lenses (or a group of them) can pivot back and forth. Again, there are disadvantages, in the form of image distortion at large swing amplitudes. Here, the incident light beam is more or less distorted, depending on how large the swinging amplitude of the lens is.

The well-known manufacturers (eg SONY, Panasonic, etc.) build electromagnetically movable Lenses in smartphone digital cameras or other high quality devices. The lens is movable back and forth along the optical axis. This is how the automatic auto focus setting works on high quality digital cameras.

As described, there are enough electric drives for digital cameras (surveillance cameras, IP webcams, etc.), but there are mainly used for the drive electric motors and transmissions. The drive systems are too coarse, too slow and it is almost impossible or very expensive to reduce these to rice grain size.

The object of the invention is based on the problem of providing a camera system for a mobile telephone equipped with a drive system which allows liquid movements of the camera, whereby the camera within the mobile telephone operates quickly and silently, With the effect almost like a human eye, it turns, taking pictures of both the back and the front of the phone, replacing a second camera.

This problem is solved with the features listed in the claims 1 to 4 and subclaims 5 to 56.

The invention is a camera system for a mobile telephone, wherein the image sensor and its optical accompanying elements, are fluidly movable and thereby able to track a target to be photographed, to make a video recording of a mobile object or person, or an automatic Rotation of the image sensor and its optics to take pictures or video recordings from different angles, preferably from behind and / or from the front (with only one image sensor to realize). It is an extremely small mobile digital camera system that can be integrated into a small mobile phone that is able to move like a human's eye or even faster and dynamically capture the field of view within existing parameters. The movement of the camera is very fast, silent, precisely controllable. The camera can rotate or rotate so that video / image capture is possible from different angles, even from the back and front of the mobile phone.

Incidentally, the invention can be designed so that the drive system is able to automatically detect whether the image sensor and its optical elements should be directed forward or backward within mobile phones.

Embodiments of the invention will be described with reference to FIGS 1 to 45 explained. Show it:

1 a variant that has a full gimbal suspension (3D axis rotation).

2 a variant with a spiral spring,

4 a fully automated tracking system that controls the motion of the image sensor

5 and 6 the operating principle of the drive,

8th to 45 various types and embodiments of this invention.

The image sensor 2 and its optical accompanying elements 5 are preferably in a small spherical housing 1 attached (from here the housing with the digital camera in it, just called ball housing or ball digital camera), that in a hollow spherical chamber (from now this is only ball socket / hollow sphere 8th called), which is only slightly larger than the globe digital camera is installed. The globe digital camera 1 can simply be placed loosely and freely rotatable in the hollow sphere, or it can have a simple gimbal or a coil spring with that of the hollow sphere 8th in this case, the bullet digital camera no longer (or only rarely) touches the hollow sphere wall. The hollow sphere is statically attached in some variants, so immobile, only the ball digital camera moves in it. In other embodiments, both the ball digital camera, and the hollow sphere is rotatable.

Specifically, a digital camera in an I-phone, smartphone or other mobile phone, can be installed so that it is electrically rotatable in the housing in it, non-contact and is suitable for both rear views and for front shots. Again, the digital camera is preferably constructed in the form of a sphere and placed in a ball socket / hollow sphere, much like the human eye places in its cavity, which is transparent or at least partially has a window through which the ball digital camera transmits the light from the environment gets. The ball digital camera is complete with image sensor 2 , Electronic components and accompanying optics elements (eg lenses, mini prism, etc.). The bullet digital camera is not rotated by conventional gear or electric motors (not manually by touch), but by one or more electromagnets 10 controlled by magnetic field interaction in targeted direction without contact rotated or pivoted. The pivoting or the rotation can take place in one or more axes. Multi-axis rotation can be achieved by a gimbal suspension 22 be realized, if the ball-digital camera should not touch the hollow sphere wall. However, the simplest version provides that the ball-digital camera, especially for small devices, in the ball socket / hollow sphere simply loose loose in it, which is electromagnetically rotated without contact. The ball digital camera does not necessarily have to be stored. It touches the walls of the ball cup / hollow sphere, however, its weight is very small and thus hardly friction arises when it is rotated back and forth by solenoid coils. The material that makes up the ball-digital camera case and the ball socket / hollow sphere should be scratch-resistant (at least the surface coatings that will rub against each other) and possibly also self-lubricating (at least in some areas). It is also conceivable to realize a non-contact magnetic field cage, which holds the digital camera ball floating in the hollow sphere, but is not absolutely necessary. The current signal transfer to the image sensor is effected by a flexible line 20 or by small induction coils also contactless. Although the digital camera can have other shapes (such as an egg, oval shaped) or provided with small edges, but the shape of a ball is best suited for it. The globe digital camera is with magnetic areas 15 provided this with the help of one or more electromagnetic coils 10 in the ball socket / hollow sphere 8th are incorporated, in any direction without contact, are pivotable / rotatable solely by magnetic field interaction force. As soon as a magnetic field is built up through the coils, the permanent magnet orients itself 13 into the globe digital camera 1 is located, automatically to the magnetic field of the electromagnetic coils. Depending on which of the coils is active, the permanent magnet also becomes the magnetic field lines 17 orient the active coils. The power signal line 20 for the ball digital camera (or its image sensor) may consist of fine twisted wires. Thus, the power supply and signal pickup can be done by the image sensor of the ball-digital camera. The ball digital camera is rotated by the electromagnets, depending on which of the solenoid coils is active in the hollow sphere, in any direction, fast and silent. Supported by the software (mainly that of the mobile phone), the target being photographed can be quickly captured and tracked, even if it moves quickly, with images always near the center of the video, including single-frame images. So-called face tracking can be easily realized because the digital camera could track the face of a moving person by their rotation and always place the face in the middle of the recorded images. The attempt to move the object to be photographed out of the center of the image is fully compensated for by pivoting the ball-digital camera until the end of the entire field of view is reached. It looks similar, just as a human pursues a moving object with his eyes without turning his head. Even when walking with a smartphone in your hand, you could talk to someone via video chat, without worrying about whether you are still in the picture or not. With the drive system, the user would always be seen in the center of the image or video when within the field of view radius. The images would be free of camera shake, no matter how hard the cellphone is panned back and forth. In a mobile phone 29 (Smartphone, for example, I-Phone) installed, at the point where the ball digital camera is located, a through hole in the form of a tunnel 28 must be installed, in which a ball socket / hollow sphere and the ball digital camera are placed, which allows a field of view to the rear and to the front. In that case, it is also possible to install the ball socket / hollow sphere movably. These can also be rotated by means of solenoid coils. However, only two positions would be necessary for the rotation of the hollow sphere: normal and rotated 180 ° backwards, thus also the number of solenoid coils on only one reducible. A permanent magnet in the hollow sphere would be based on the current magnetic field of the coil. A reversal of the magnetic field of the coil would then rotate the ball socket / hollow sphere backwards.

• – ein elektrostatisches Antrieb ist ebenso sehr effizient (der wird oft als Mikro-Aktor für Spiegel-Chips verwendet), allerdings erfordert er eine höhere Spannung, die durch elektronische Spannungs-Wandler 50 realisierbar ist. Hier werden spezielle Elektroden 49 unter Spannung gesetzt, die dann anziehende oder abstoßende Kräfte durch elektrische Felder generieren können.
• – ein Piezoelement-Antrieb ist sehr schnell und kann auch eingebaut werden. Die Frequenz der Piezoelemente 51 ist erstaunlich hoch und kann mehrere kHz bis MHz betragen, was allerdings nicht voll ausgeschöpft werden sollte, weil dann durch die Trägheit der Kugel-Digitalkamera erhebliche Schäden am Bildsensor verursacht werden können (41).
• – ein Antriebs-System mit Magnetostriktions-Elemente ist ebenso als Mikro-Aktor-System geeignet und ist recht schnell, wird aber hier nicht verwendet, weil die anderen Methoden weitgehend optimaler sind.
• – Zuletzt kommen auch elektroaktive Kunststoff-Streifen 52 oder elektroaktive Kunststoff-Spiralen 37 als Mikro-Aktoren in Frage. Diese sind ebenso effektiv in Erzeugung von Drehmomenten, die auf die Kugel-Digitalkamera übertragbar sind (42).

The drive for the image sensor and its optics can be designed not only electromagnetically but in other forms and principles:

• - An electrostatic drive is also very efficient (which is often used as a micro-actuator for mirror chips), however, it requires a higher voltage by electronic voltage converters 50 is feasible. Here are special electrodes 49 put under tension, which can then generate attractive or repulsive forces by electric fields.
• - A piezo element drive is very fast and can also be installed. The frequency of the piezo elements 51 is amazingly high and can be several kHz to MHz, but this should not be fully exploited, because then caused by the inertia of the ball digital camera significant damage to the image sensor ( 41 ).
• - A drive system with magnetostrictive elements is also suitable as a micro-actuator system and is quite fast, but is not used here, because the other methods are largely optimal.
• - Finally come electroactive plastic strips 52 or electroactive plastic spirals 37 as micro-actuators in question. These are equally effective in generating torques that are transferable to the ball digital camera ( 42 ).

The digital camera of the invention here has several advantages over the prior art. This digital camera is rotated contactlessly via electromagnetic fields within the mobile phone, the rotation being instantaneous and silent, which is also optimal for discrete surveillance purposes. The digital camera here is not only turned back and forth, but also a target tracking can be realized. Through software-controlled motion, automatic target tracking can be easily realized. Because not the whole mobile phone housing (digital camera carrier device) rotates, but only the part in which the image sensor and its optics are located, an extremely fast tilting is possible. This very fast response can also be easily used for image stabilization purposes (such as a kind of image stabilizer system). The bullet digital camera would look like an human eye back and forth, or lose sight of the observed target and also perform very small and extremely fast counter-rotating panning movements, thereby also small digit movements by the user during the image - or video recordings would be perfectly balanced. The drive system can rotate the ball digital camera back and forth very quickly, also impulsively and with very small movements. Counter-movements can be used very well to compensate for dithering during video or image capture. The conventional digital cameras in high-quality mobile phones use a movable lens for this purpose, which performs very small but very fast panning movements, which counteract the dithering, with the focal point of the image on the image sensor always remains in the same place, although the camera slightly back and forth It wobbles with the rhythm of the shaking movements of the camera user. Thus, conventional image stabilizers are usually built. The drive system for the ball camera can very well compensate for such dithering movements. Thus, an image stabilizer would not necessarily be necessary. This process can be controlled via a control unit similar to conventional digital cameras. If the focal point in the sensor image changes very quickly, this can be an indication that digit movements are taking place, with the drive system attempting to compensate for this with the rapid swiveling of the ball digital camera.

Through very small swings you can even take 3D images with just one camera. First a picture is taken, then the ball camera is only slightly and quickly panned, whereby another picture is taken. The object to be photographed would then have been taken from two different perspectives, albeit with only a few mm displacement, but software support could well create a 3D image afterwards. The same can also be used for video recordings. The bullet camera can be electromagnetically displaced in rapid dithering, with an image captured at each stop position, just prior to reverse motion. The dithering of the ball camera is easily accomplished with an electronic oscillator (eg, an electronic mono or bipolar flip-flop, an electronic multivibrator circuit, or a logic oscillator circuit) that generates an AC signal that is passed to the coils, to create. With software support, it would be possible to separate the images from the left and right stop positions into an overall video, which would then be passed to viewers by conventional 3D image playback methods.

The bullet digital camera will be rotated by electromagnets in any direction, much like a rotor in an electric motor. Of course, here does not take place over 360 ° rotation, which stops continuously, as in an electric motor, but rather these pivotal movements. In contrast to an electric motor, the movements of the ball-digital camera are not only in one axis, but in any direction.

In one variant, to realize a magnetic-field interaction between the externally mounted solenoid coils and the ball digital camera, is quite sufficient when the ball-digital camera 1 Meridial or Equatorial a magnet ring 14 having a magnet inside or having a magnetized area ( 6 ). With the help of electromagnetic coils outside, which are placed in the ball socket / hollow sphere at different locations and which are supplied with power by a control, the ball digital camera is rotated without contact. The more the number and the smaller the electromagnets are built into the ball socket / hollow sphere, the more precise is the rotation of the ball digital camera. By coordinating magnetic field intensity control of the coils, one can theoretically use only three or four coils to move the ball in any direction. Because the ball digital camera is rotatable within the ball socket / hollow sphere, it can be used both as a rear camera and a front camera. Of course, the ball-digital camera does not rotate uncontrolled, but this is very accurately positioned on the desired field of view via the control of the coils. Stopping in the desired position can also be done via the magnetic fields of the coils, by counter-field generation, counteracting the panning, but rapidly attenuated as the ball slows down. The counterforce should only slow the ball, but not immediately turn in the opposite direction, because then oscillating movements arise that make the picture blurry. The ball socket / hollow sphere can be built completely transparent, or it can be placed in certain places with large light windows 9 equipped, through which the light arrives from the image motifs, or environment in the digital camera ball and its sensor also reached. In a transparent ball socket / hollow sphere, the digital camera is mounted like a small ball in a transparent capsule and is moved without contact by electromagnets. Small additional optics elements (lenses) can successfully correct for slight image distortion caused by the spherical windows. The digital camera can also be driven more or less out of the mobile phone to increase the viewing angle. In the case would be another solenoid coil 10 necessary, which is the ball socket / hollow sphere 8th or a hollow cylinder in which the ball-digital camera would be mounted, more or less drives out of the mobile phone.

An advantage of the invention is the fact that no extra light deflecting elements need to be installed and this simplifies the matter enormously. The Conductor Link between the Bullet Digital Camera and the signal processing unit located outside the encapsulated sphere is a slightly longer, flexible conduit 20 that does not interfere with the movement of the camera. These conductors or micro-cables must withstand many swings and always allow a perfect signal transmission. Interweaving micro-cables, as known from loudspeaker membranes, can withstand a great many vibrations. Although the bullet digital camera not only vibrates here, but also turns it back and forth, such cables can withstand a few years of daily use. As described, the ball digital camera can be easily installed loosely in the ball socket / hollow sphere without any bearings. Optimal and easy would be a two-axis gimbal 23 (It is enough a much simplified gimbal, with only a small arm, as in the 7 is shown to install). Also a coil spring 25 , which allows any movements in all directions, which connects the ball digital camera and the ball socket / hollow sphere resilient, can be used ( 7a ). The movements are carried out without contact by electromagnetic drive. The unwanted further vibrations of the ball digital camera, if it is hung on a coil spring, can also be damped quickly by electromagnetic or eddy current technology. A control unit 21 can when reaching a certain rotational position of the ball digital camera 1 via solenoid coils 10 Generate counter-magnetic fields quickly, which counteract the ball-digital camera rotation or their oscillations. When using cardan suspension, or in variants where the ball-digital camera is simply loose in the ball socket / hollow sphere, no further oscillations are to be expected once the desired positioning is achieved and the active electromagnetic coils are switched off. Because the camera 1 can also rotate about the optical axis, the photographing or generation of perfect images even when tilting the mobile phone is possible. The picture would always be perfectly straight, no matter how you tilt the phone. Through the control unit and, of course, software support for the mobile phone, the digital camera image sensor can automatically be rotated to take widescreen pictures for video recordings. When shooting single frames, if desired, perfect vertical alignment of the photographs can be achieved, which is made possible by the 90 ° rotation of the image sensor.

The controller can divert the bullet digital camera so that with a relatively high frequency (eg several hundred Hz), this oscillates back and forth, so that simultaneous image or video recordings from motifs are far apart, different perspectives, very wide panorama Images or images from both the back and the front of the mobile phone are possible without the mobile phone must be swiveled by hand. Only the shutter speeds, or the image sensor inputs and shutdowns should be synchronized so that the images from different motifs that are far apart, images from the back and the front, are separated. For example, the first millisecond delivers an image from the image motif A, which is located on the right from the viewpoint of the mobile phone, the second millisecond will pivot the ball digital camera and the subject B in the field of view, which is located to the left of the mobile phone ( 8th ). The same can be done with the front and back images (because the bullet digital camera was rotated from front to back). When shooting video, the pan can be paced back and forth in sync with the picture frequency, so you can simultaneously create two videos from two different subjects. That would mean, for. B. in the first millisecond the subject A is recorded, the second millisecond is the pivoting to B, during the third millisecond, the image is taken from the subject B, then during the fourth millisecond, the pivoting from B to A, then during the the fifth millisecond, the motif A was taken, then in the sixth millisecond, the pivoting from A to B takes place and so on. The transition can be hidden by shutter speeds or sensor switching on and off. The autofocus function can make the settings once and then "remember" them in the different images, so no new readjustment is required. When rotating through 180 °, while traversing the light axis, the image is not blurred, but only the light-receiving field from the front or back changed ( 8th ).

Assisted with motion sensor support or software coupled with a gravitational sensor or combined with a conventional image stabilization device 7 , the system can be designed as a perfect stabilization system against blurred images.

In a variant that in the 10 is shown, the surface of a plastic window of the mobile phone that protects the visual field of the image sensor, from a special polymer / plastic 40 (eg, electroactive plastic) which is capable of temporarily forming a dome outwardly, either electrically or thermally controlled. Because the edge of the window dome with a non-stretchy ring 65 is limited, this will promote the formation of the dome, which results from the expansion of the electroactive polymer element. The voltage applied to the extension of the window tip can not extend over the ring. A slight mechanical bias, which tends to form a dome outwards, results in formation of the dome upon electrical irritation of the polymer. Because the window is slightly bent outwards even when inactive, an expansion will initiate the dome formation to the outside. In the window-top, the spherical camera can be driven by an electromagnetic coil, slip into it and thereby significantly expand the angle, which would be interesting, such as when the mobile phone is on the table and you want to monitor from this position the whole room. Once the monitoring is no longer required or interrupted by the user, the voltage to electroactive polymer element can be interrupted and the formed window tip regains the normal, almost flat shape again. In this case, the camera will also sink back into the normal position.

Due to the rotation of the digital camera and the creation of the window dome, the field of view would be monitored almost semi-spherically. With a sound control system coupled with the drive system, the digital camera could then be automatically directed to where the sound or voice comes from. In this case, the mobile phone should have a stereo microphone or directional microphone. An electronic coupling of the two systems, so audio and optical detection systems, the drive system can be controlled so that the movements of the digital camera are automated. In this way, the camera would be aligned exactly in the direction of the voice / sound source for image recording / video recording.

The electromagnetic drive of the ball digital camera, is relatively simple in construction. The basis for this is a permanent magnet body 13 inside the globe digital camera 1 , a magnetized area 15 on the globe digital camera plane 19 or a permanent magnet ring 14 Being mounted in the circumference of the globe digital camera like a meridian, the main thing outside of the field of view of the ball digital camera ( 11 ). This permanent magnet (regardless of whether it is a magnetized area, permanent magnet body, permanent magnet ring) is controlled in any direction by electromagnetic coils that are permanently installed in the wall of the ball socket / hollow sphere (can also be installed completely outside the ball socket / hollow sphere) turned. The damping of the vibrations that arise during rapid standstill in one position, are selectively attenuated by weaker magnetic pulses that counteract the vibrations. Damping can also be done by short circuiting (of course electronically by the controller) the electroless solenoid coils. According to Lorenz's law, the vibrations of the permanent magnet into the coils will cause electromagnetic induction, resulting in the generation of very small currents and voltages. Closing the coils short, these currents will exert a braking force on the permanent magnet, thus dampening the vibrations quickly. For the damping of vibrations, other methods can be used very effectively. For example, on the outer wall of the ball-digital camera or inner wall of the hollow sphere you can use small bristles 63 or small, light sponge body 30 or sponge coating, then lightly touch the hollow sphere wall and immediately stop the ball digital camera in the absence of torque.

The ball-digital camera can track a moving object after it has been optically detected, until the field of view is over, or the freedom of movement within the movement angle is exhausted. However, this is supported by software (similar to today's mobile phones, with a person's face being tagged and tracked as soon as it is detected). Often in such cases, the autofocus settings are always adjusted to the face of the subject so that a clear picture is taken of them.

The rotatable ball camera 1 can with a return spring 26 or an additional rest position permanent magnet which attracts a ferromagnetic region or ferromagnet body (preferably iron or nickel) in a rest position ( 12 ). The return actuator spring or the rest position permanent magnet 48 ensure that when the ball camera is rotated by electromagnetic force, a certain magnetic field force turns the ball to a certain position. Advantageous is the use of permanent magnets instead of the return spring, because the permanent magnet unfolds its effect contactless and does not hinder the rotation. By amplifying the magnetic field of the electromagnetic coil, the camera is rotated even further until the magnetic field force and the return spring force are balanced. The direction of rotation can be easily realized with at least three (or more preferably four) solenoid coils arranged in a triangular formation. Instead of a permanent magnet in the ball camera (ball digital camera), you can only with a small ferromagnet body 16 realize the rotation, which is installed in one place in the ball camera. This ferromagnet body is replaced by the three staggered solenoid coils 10 attracted and that in the direction determined by the magnetic force of the coils. Is the coil 1 active, the camera is rotated in direction A. Will the coil 2 activated, then the digital camera turns in direction B. Depending on how strong the magnetic field of the coil 2 is the ball camera, more or less rotated. But are z. B. at the same time the coils 1 and 3 Then, the camera is rotated in an intermediate direction, ie direction C. Depending on which of the coils is stronger, or is supplied with more power, then the rotation will be more in the direction of the stronger coil. Thus also the camera turned in any direction ( 13 ). A damping of the vibrations of the ball camera can be achieved electronically by the control of the coils, where several hundreds or even thousands of times per second, small impulses are given to the coils, which counteract the vibrations, with the aim of the vibrations of the ball To dampen the camera quickly. The real-time detection of the vibrations can be achieved by means of an additional control coupled to the coils or directly via the coil control. The tiny coil induction fluctuations indicate that the ball camera is vibrating ( 14 ). A digital detection of such induction fluctuations, realizes the vibrations of the ball camera in real time. Countermeasure with small current pulses can dampen these oscillations as fast as lightning and bring the ball camera to rest. Both for the detection, as well as counter-control, the same solenoid coils can be used, or even separate coils (in which case at least six coils would then be necessary). If separate coils are to be used then the detection coils can take on the role of induction fluctuations sensor coils.

As a vibration damper and small bristles or sponge pieces, which are placed between the rotatable ball camera and the hollow sphere, are optimally suitable. The bristles must be very wel and coupled at one end either to the ball-camera outer wall or to the hollow-sphere wall, leaving the other end free. As a result of the contact, a small mechanical resistance is exerted on the rotatable ball camera, thus achieving an immediate damping of the vibrations.

The electromagnetic drive is quite easy to implement and can work with relatively little power and low voltage, which benefits the battery. The frequency of the vibrations can be very high and amount to several KHz.

In the 15 the variant is shown with solenoid coils, with the ball camera 1 in a gimbal 22 or partial cardan suspension 23 is installed. The image sensor 2 and its optics elements 5 are ideally mounted in a ball housing which is movable in a hollow spherical chamber 8th attached, which is transparent, or Blicklichtfenster 9 having. The spherical housing (ball camera / ball digital camera) is placed in the transparent ball socket / hollow sphere. The sphere camera is slightly smaller than the hollow sphere, thus freely movable in it. The recording direction of the camera is through the electromagnetic coils 10 determined, which are installed on the hollow sphere wall. The electric and Signal transmission from the sensor to the evaluation unit is made by a very thin and extremely flexible cable 20 which is ideally shaped like a spring. The fine signal lines are intertwined, much like the leads of a magnetic coil in a speaker membrane. This method has proven itself for a long time to protect the lines from damage. It is well-known that the loudspeaker membrane during its entire "life" undergoes a very high number of oscillations (several hundreds of billions !!), whereby the power lines between the housing and the loudspeaker coil undergo innumerable movements and oscillations, even after years remain intact. The same technique could be used here as well. This would ensure long-lasting, flawless signal and power transmission between the image sensor and the mobile phone (eg, a smartphone) despite the movement of the image sensor. Using a longer conduit that is finely intertwined, and which is also more or less helically shaped like a spring, may allow for nearly complete rotation of the image sensor and its optical elements. The inner diameter of the ball socket / hollow sphere is only slightly larger than the ball camera 1 in which the image sensor and its accompanying elements are installed. Due to the magnetic field interaction between the magnetic fields of the electromagnetic coil 10 in the hollow sphere and the permanent magnet 13 in the rotatable sphere camera, one can achieve any rotation of the sphere camera. Likewise the lighting elements 53 Whether they emit radiation in the spectrum of visible light or in the infrared range, they can be moved with the ball camera. This allows optimal illumination that tracks the movement of the field of view of the ball camera. Also a flash, preferably as a light emitting diode 54 built into the bullet camera, can be used for this ( 5 ). It is also conceivable the use of laser diodes as lighting means. The laser diodes radiate very intensively and can perfectly illuminate the subject. A combination of three basic light colors (RGB), or the installation of at least three laser diodes, at least one of which emits a red, the second blue and the third green laser light, a total white light can be generated, which illuminates the field of view.

The 18 shows a variant that is a full gimbal 22 having. Here is a rotation of the ball camera in 3D possible, or all on three space axes, although a simplified version with a partial gimbal 23 with only two axes of rotation, would do well. The electromagnet system can be extremely fast, absolutely silent and precisely controllable. Mobile phones equipped with it can quickly detect and track moving targets. Whether used on mobile phones, wrist watches, tablet PCs, laptops, or other devices, it meets all the technical requirements for capturing fast moving targets. The camera housing can also be built in a cylindrical or other shape, which is held either by permanent magnet fields in a magnetic field cage, or by a small spring in the most central position in the capsule. Attached to the housing is a small flexible electrical micro cable or cable that is coupled to the camera sensor and its electrical companion elements. This electrical wire also serves as a signal line and connects the camera sensor to the power supply and signal processing components of the mobile phone that the camera incorporates.

In a variant that in the 19 is shown, the ball camera, in which the camera sensor and its optics are mounted on a spring 25 attached, with side solenoid coils 10 (At least three pieces arranged at 120 ° angle to each other), are attached, which can attract the ball camera tangentially in any direction. By putting on the ball camera 1 , the angle of view of the camera is changed and that in the direction of how the housing is pulled. The feather 25 , to which the ball camera is attached, provides a small resistance, which is overcome by small solenoid coils. The stronger the magnetic field of the corresponding coil, the stronger the inclination of the spring and thus also the angle of inclination of the ball camera. The solenoid coils are controlled by an electronic control, which in turn is controlled by software. The star arrangement of the three coils allows any pivoting direction of the camera housing. The tilt is even finer when more than three coils are installed. Absolutely necessary, however, are not more than three. In order to realize a fine turn to the rear, the hollow sphere can also be turned backwards ( 20 ). The rotation of the hollow sphere 8th One can with two fix positions through only one coil 38 outside the hollow sphere and a permanent magnet 39 determine in the wall of the hollow sphere. If the coil is reversed, then the ball socket / hollow sphere also rotates in the other direction in a flash, by 180 °. If the coil becomes inactive, then the hollow sphere retains this position until the coil is reversed, so that a continuous power supply to the coil is not necessary. In that case, the star-shaped solenoid coils that pivot the ball-type camera would always be located in the back of the hemisphere, and from there they would pivot the ball-point camera in any direction ( 21 ).

An electrostatic drive can also be well suited for this purpose. This drive would be similar to the a micro-mirror element. However, high voltages are required here because the ball-digital camera would then move by the interaction of electrostatic fields. A high voltage converter 50 and all electrodes 49 would be necessary. This method is already successfully used with DLP chips (Digital Light Processor), or as a drive for micro mirrors ( 43 ). To make the execution more economical, one can use the electrostatically fixed charged sphere 64 (similar to electrostatic films that adhere to windows alone with permanent electrostatic charge). By the electric field interaction between the traveling field of the electrodes 49 and the electrostatically permanently charged areas 69 in the ball, can realize a rotation of the ball camera with it.

The spherical shape of the camera housing may not necessarily be, but is optimal in the case. The ball camera can with a spring 26 equipped to keep them in a quiet position. The spring may be a helical spring having a plurality of turns that allow rotation of the ball in each direction yet exert a small spring force that tends to orient the ball to an initial position (US Pat. 19 ).

Another option is to hold the ball with the help of permanent magnets, floating in the hollow sphere. However, this method would be quite expensive and superfluous for small devices.

The variant with the cardan suspension 22 allows very precise execution of the rotation of the ball camera, on the other hand, the variant with the coil spring 25 is very simple and also economically very cheap. Here, behind the ball camera connected to another spring, which has the role of a spring and this always aligns in the starting position. Instead of this spring can also very well a permanent magnet, which is statically attached and a ferromagnet 16 , or portion of ferromagnetic material incorporated in or on the ball-type camera, or another permanent magnet mounted in the ball-type camera, which are attractively aligned with each other, or a ferromagnet portion or ferromagnet body ( eg iron or nickel) ( 16 ). The spring or the permanent magnet ensures that a tension force, which holds the ball in a certain position, is generated. With electromagnetic rotation of the ball camera, a magnetic field force will turn the ball to a certain position. By amplifying the magnetic field of the electromagnetic coil, the camera is rotated even further until the magnetic field force and the return spring force are balanced. The direction of rotation can be easily realized with only three solenoid coils arranged in triangular formation in the rear half-sphere region. A small ferromagnet body 16 standing in a spot in the bullet camera 1 is installed, is attracted by these three offset coils and in the direction that is determined by the magnetic force of the coils. Is the coil 1 active, the camera is rotated in direction A ( 17 ). Will the coil 2 activated, then the camera turns in direction B. Depending on how strong the magnetic field of the coil 2 is, the camera ball, more or less rotated. But are z. B. at the same time the coils 1 and 3 activated, then the camera is rotated in an intermediate direction, ie direction C ( 17 ). Depending on which of the coils generates a stronger magnetic field, or is supplied with more power, then the rotation will be largely in the direction of the stronger coil. Thus, the camera rotated in any direction. A damping of the vibrations of the ball camera can be achieved electronically by the control of the coils, where several hundreds or even thousands of times per second, small impulses are given to the coils, with the aim to dampen the vibrations of the ball camera quickly, or to brake the further rotation or oscillation. The detection of the vibrations can be achieved by means of an additional control, which is coupled to the coils, or directly via the coil control. The tiny coil-induction fluctuations indicate that the bullet camera is vibrating. A digital detection of such induction fluctuations, realizes the vibrations of the ball camera in real time. Countermeasure with small current pulses can dampen these oscillations as fast as lightning and bring the ball camera to rest. Both for the detection, as well as counter-control, the same solenoid coils can be used, or even separate coils (in which case at least six coils would then be necessary). If separate coils are to be used then the detection coils can take on the role of induction fluctuations sensor coils.

An ultra-thin and extremely flexible cable connects the sensor to the electronics and control of the main unit where the camera is installed. The line should not be too tight, because if the ball continues to turn, the length would have to reach, so as not to prevent them from turning. It is best if the line is shaped like a spiral spring. The opening of the hollow sphere 8th , or the viewing window 9 is large enough to the viewing angle of the camera sensor 2 not to be restricted even when turning.

The system is able to move the camera sensor so fast in real time the ball camera, so that a tracking of fast moving targets, or even an optical compensation for the Disturbing movements of the filmer is possible. Therefore, the system is also perfectly suited as an image stabilizer system. Conceivable is also suitable as a replacement for the steady-cam, because much smaller and lighter. The system does not necessarily need a cardanic suspension / gimbal or gyroscope outside again. Gyrosensors or vibration sensors and an evaluation unit can complement the stabilization. You can install a small flywheel or flywheel in the sensor, which would allow perfect stabilization. Above all, the components would be much smaller, and would hardly disturb. It would also be largely maintenance-free.

In the 22 is a simple representation of the principle whereby the system is constructed as follows: the sphere camera (image sensor housing and its optics) is with a very small ferromagnetic body 16 equipped (eg iron, nickel, or a magnetically attractable alloy) on the optical axis 55 is installed on the back. On the hollow sphere 8th are at least three small solenoid coils 10 built into the wall of the hollow sphere 18 are integrated, or are installed outside the sphere (because if they were inside, then they would prevent the free rotation of the sensor ball). The arrangement of the coils is also star-shaped here. Their task is to generate a magnetic field which exerts an attractive force on a point (in the future referred to as black dot here) in which the ferromagnetic part (eg small piece of iron) is located on the sensor ball. Depending on which of the coils is activated, so will the rotation of the ball. As a rule, only three coils are sufficient to effect all directions of rotation. In that case, three main directions would be feasible in the activation of the individual coils, but innumerable many directions of rotation, by the combination of all three coils. The coils are not only to turn on and off, but their magnetic field is controlled electronically stepwise or continuously. When the coils 1 and 2 are briefly activated, then the black dot is tightened so that it comes approximately into a connecting line between the two coils. Will the coil 3 activated, then the black dot moves there. On the opposite side of the ball camera simultaneously rotates with the optical axis and the detection range of the camera.

The 23 shows a variant, wherein instead of the ferromagnet, a permanent magnet 13 in the ball camera 1 is installed. Here, the permanent magnet depends on the magnetic field lines 17 the active coils 10 and thus turns the ball camera 1 , depending on which of the coils is active.

The 24 shows a variant, with many coils in the hollow sphere wall 18 are incorporated, which can be activated individually or in groups. With single activation, the permanent magnet is directed 13 in the ball camera 1 is installed, according to the magnetic field lines 17 the active coil and thus the camera is turning in the direction. Because the motion of the ball camera is sufficient in two axes, a partial gimbal can be used 23 be installed with minimal parts. Thus, only a quarter-circle-shaped arm would be 56 sufficient, the two joint points 24 has, the ball camera 1 to maintain their freedom of movement in two axes. This does not obstruct the view of the camera.

In the 25 a variant has been shown in which instead of the permanent magnet, a ferromagnetic (iron, nickel, etc.) coating is present in a small area, which is installed on the ball camera. The ferromagnetic region 57 can be applied in the form of a thin coating on the ball camera. The torque or forces necessary to turn the ball are very weak. For the device in a smartphone, you only need a power of about 2-6 mW on the coil to quickly turn the ball camera back and forth.

In the 26 The ball camera is shown using electromagnetic coils 10 is rotated in any direction. She has a magnetic ring 14 , a magnet inside or a magnetized area. The more and smaller electromagnets are installed on the outside, the more precise the rotation of the ball takes place. By coordinating magnetic field intensity control of the coils, one can theoretically use three or more coils to move the ball in any direction. Fine bristles 63 which are fixedly coupled either to the hollow sphere wall with free ends in contact with the outer wall of the ball camera or vice versa, fixedly coupled to the outer wall of the ball camera and with free ends touching the wall of the hollow sphere, keeping the distance between the Ball camera and the ball socket / hollow sphere constant and do not disturb the rotation of the ball.

The 27 shows a variant in a smartphone 29 (Mobile phone with PC features) is installed. The mobile phone camera (eg I-phone or smartphone camera) can be installed so that it is rotatable inside it and is suitable for both rear views and for front shots. Because the camera only moves from the inside, the phone looks aesthetically very good. The camera is also here in the form of a ball, z. B. installed in a hollow sphere, similar to how the human eye placed in a cavity that is transparent in at least one area and the camera by an electromagnet 10 is rotatable. The rotation takes place in one or more axes. Multi-axis rotation can also be characterized by loose Place in the hollow sphere, a gimbal suspension 22 , a spiral spring 25 , or be realized by a non-contact magnetic field cage. The current signal is taken off by a flexible cable 20 or by small electromagnets also contactless.

It is possible to install in a smartphone a simplistic mini-gimbal suspension in which the ball camera is attached and thus in each direction in three axes is pivotally ( 39 ). Face or person tracking can be easily realized because the camera could track the face through its rotation. In order to take pictures to the rear, the smartphone should then but at the point of a through hole / bore or tunnel have, in which the camera is installed, so that when the camera is directed backwards or forwards, has a clear view.

The hollow sphere, which forms the cage housing for the ball camera in a Smartphone, is only slightly larger than the ball camera itself and exhibits several electromagnetic coils. Due to the magnetic field interaction between the fields of the electromagnetic coils of the housing and permanent magnet of the ball camera, a precise controlled swinging will be achieved. Sure you can install instead of the permanent magnet, in the ball camera solenoid coils, but then you would have to ensure the power supply of this coil, which would be feasible by flexible lines, but the effort would be unnecessary, because a permanent magnet does its job very well would do. Using permanent magnets that are very small and sophisticated mounted on the ball camera, you can float the ball in the hollow sphere and reach a non-contact rotation controlled by the electromagnetic coils, relatively easy. Likewise the lighting elements 53 Whether they are in the visible light spectra or in the infrared range, they can be integrated into the ball camera and moved with the image sensors and its optics. This allows optimal lighting that tracks the movement of the image sensors. Also a flash, in this case because of the small size of the image sensors, preferably as laser diodes or LEDs 54 built-in, can be used for 5 or 15 ).

The drive for the camera from a smartphone (generally mobile phones), can be designed so that it can be gradually or completely electrically controlled from front to back electrically controlled and absolutely silent, non-contact and lightning fast. Lightning-fast back-to-front rotation and vice-versa can be performed so quickly that you can simultaneously take pictures or record videos from both sides. It is sufficient if the direction change takes place about 50 times per second, then the electronic shutter can record the video recording signals 25 times from the back and 25 times from the front, and thus 25 complete images per second from one side and just as much from the other side of the Record mobile phones. Even fast panoramic images or 360 ° images / videos would be easily feasible with this device. The horizontal tilt of the camera would be just as fast as the vertical. The ball camera is movable in it (whether on a gimbal or not) and can thus be pivoted in any direction. When using cardan suspension or partial cardan suspension (with only two motion-freedom axes), a viscous, gel-like fluid on the gimbal suspension axles can serve very well as a damper. This provides a bit of resistance during the pivoting of the ball camera and is quite sufficient to dampen the vibrations that arise during the electromagnetic positioning. Without the damper, the camera would swing at least a few times back and forth so that possibly unclear images would arise. With corresponding software or app (application, software application) you can make fast pictures from different perspectives. The speed with which the ball camera moves is extremely high. This also makes it possible to track the fast-moving targets. Also the braking of the ball camera succeed quite fast (can be initiated automatically by trigger button), so that crystal-clear single-frame shots are possible. For a 3D image capture, two such cameras and systems are needed, which are best built at a distance from each other ( 28 ). The rotation can be done by a single controller and should, of course, be synchronous, especially with 3D video recordings.

In all variants, the camera will be installed like an eye of a human in a ball socket / hollow sphere and also be equipped with a tracking mechanism that is controlled by a software that then automatically tracks the detected person or face. The camera can be designed to be easily lifted out of the cellphone electromagnetically or electrically, so it will look a bit out if the device stays somewhere ( 29 ). The cover lens or dome or a transparent hollow cylinder 58 in which the camera is located, can be easily moved out in this case. Ideal would be a transparent hollow cylinder with dome-shaped ends. That could be with a ferromagnetic ring 59 in the middle, which is attracted by an externally statically mounted electromagnetic coil, wherein the cylinder 58 , depending on how the mobile phone is, is raised, or the camera forward or to leaves behind. Instead of the ferromagnetic ring, can also be a permanent magnet or permanent magnet ring 14 installed, which then moves, depending on how the electromagnetic coil 38 is poled. The dome-shaped ends, of course, are transparent and each form a window through which the camera sensor "can look out". Through the knoll hardly arises, or a slight distortion of the image, which is predictable and software moderately easily correctable. The use of a correction lens in the optical system of the image sensor can also cancel the distortion.

The variant with the magnetic suspension is quite complicated, but also feasible. There, the image sensor will spin back and forth in any direction. The bullet camera here literally floats in the hollow sphere, which is made of a transparent material. The electrical and signal transmission from the sensor to the evaluation unit is also done here by very thin and extremely flexible cable, which is ideally built like a spring. Using a longer lead, which is finely intertwined, and which is also more or less spiral-shaped, can allow almost complete rotation of the image sensors.

The 30 shows a variant that is equipped with a sound source detection system. This is a directional microphone or a stereo microphone 60 used to locate the sound source. Once this is done, the drive system is controlled via a controller so that the camera is aimed directly where the sound source is located (the camera "looks in the direction of the sound source"). That would be handy if you record videos and the recorded person also speaks. The camera would automatically track the sound source in this case.

The tracking of fast objects can be supported by the software of the mobile phone. On the screen of the mobile phone, one can mark an object by finger-touch and this would then automatically track the camera, no matter how it moves or how the mobile phone is held. However, the main task is done by the drive system, which allows the non-contact, fast rotation of the image sensor.

When taking pictures or recording video using conventional mobile phones (smartphones), you notice that the objects that are on the edge are often slightly distorted. This is because the image sensor is built flat and the optics correction elements that could fix the problem barely find room in a smartphone. The image sensor should not necessarily be flat, but it can be slightly concave 46 be built to better imitate the retina of the human eye. In this case, hardly any distortions of the image motif would be perceptible ( 31 ). For the manufacturing process of such image sensors, a dome-shaped micro-mat made of plastic 47 , which has a memory effect, can be used very well. Once the doping is complete, and the physical strength of the sensor is reached, the dome-shaped plastic part will bend back flat and thus detach from the sensor ( 45 ).

On the 32 a variant has been shown, wherein the stopping of the ball camera in a certain position via an electromagnetically movable pen 61 he follows. Fast target tracking is via electromagnetic drive. Once the desired position of the ball is reached, it must then be stopped in the position and held so. The stopping also takes place electromagnetically, it can either by a small pin which is moved out electromagnetically from the hollow sphere wall in the direction of the ball camera and then touched

Also prove to be small electrically brakable ball bearings, the permanent magnet micro-spheres 42 exist between the hollow-sphere housing and the ball-camera housing ( 34 ). The micro-balls 42 Continue to roll unimpeded until it is electromagnetically from a coil 43 be attracted and arranged and thus stopped by increasing the frictional force. The balls may be made of a ferromagnetic material, e.g. As iron or nickel alloys, or even better, they are made of permanent magnets ( 34 ). As long as the underlying electromagnetic coil is inactive, these beads rotate almost smoothly and unhindered. The beads, which are magnetized or made of permanent magnets, have the advantage that can be stopped very quickly by the magnetic field interaction with the statically mounted coils on the hollow sphere wall, because the magnetic areas occupy a certain orientation on the solenoid coil fields , The balls can also have several magnetic poles, z. B. 4, 6, 8, or more. The micro-sphere will continue to roll unimpeded until it is electromagnetically attracted or placed. The micro-balls, which consist of a permanent magnet are easy to control. Once the control coil is activated, these take a magnetic arrangement based on the magnetic field lines of the control coil, which is directly below those and stop automatically. The control coil can be a ferromagnetic core 44 with a small tip, in which the magnetic field is built up concentrated. Once the electromagnetic control coil is activated, this will affect the movement of the micro-sphere and this at the Prevent further rotation. Thus, the ball camera is prevented from rotating. The braking takes place via extremely short current pulses at the brake coils. However, the controller may power the brake coils for a long time or permanently when rigid positioning of the rotary ball camera is desired. It should be mentioned that not all beads 42 must consist of permanent magnets. It is sufficient if one or two beads are electromagnetically controlled brakes, the others can be simple inactive plastic beads, which form a kind of camp in which slides the ball camera smoothly.

Also a mechanical switch 45 ( 35 ) can accomplish a braking of the rotary motion of the ball camera. In any case, the ball-camera rotation would thus not only be electronically but also manually controllable.

The ball camera does not necessarily have to turn completely, but it is sufficient for many applications, just a slight tilt in two axes (two-dimensional movement - up, down, right, left, and thus any combination between these four directions), on many Ways can be achieved.

The variant used in the 36 (A-side, b-plan view) is shown, shows a ball-camera, with several individually or groupwise controllable solenoid coils built very narrow and annular, include the hollow sphere and are installed several times, which are similar to earth meridians arranged , missing in the field of view of the ball camera. The electromagnetic coils overlap at least at two points. The imaginary line connecting these two points forms the axis of rotation of the sphere camera. In order to realize another axis of rotation around which the ball camera should turn, another group of electromagnetic coils must be installed, which are offset by 90 ° and also form a meridian arrangement. Thus, the electromagnetic coils are present in at least two groups each in two meridian arrangements, one meridian arrangement being arranged in a vertical axis and the other in a horizontal axis. The coils are very narrow and can be activated individually or in groups. Depending on which of the coils is active, the ball camera, which has a permanent magnet in it, to align their magnetic field lines. In order to achieve a smooth and precise rotation of the ball camera, by activating and deactivating the coils in order, a traveling magnetic field is generated which rotates the ball camera. The electromagnetic coils are arranged to be gradually tilted on the horizontal axis and pivoted on the vertical axis, the coils of the respective groups touching at least two points each. This arrangement 12 may be advantageous to precisely rotate the ball camera in any direction. The pivoting or rotation may be stepwise by single coil activation, or steplessly when multiple coils are activated, wherein in one order the coil initially located at full strength forms a magnetic field and then gently builds up the magnetic field to the second coil gets weaker during the first and so on. Through a magnetic field generation (similar to electric motors with rotating magnetic field, or rotating field technology), practically wanders the magnetic field, or turns and thus also the ball camera.

The variants in a smartphone 29 built-in, can be designed so that the ball digital camera 1 additionally in the optical axis 55 is rotatable. This variant is interesting, because no matter how straight or oblique one holds the smartphone when taking pictures, always good even images are created when this function is activated. In video mode, the ball digital camera is rotated so that the images are perfectly horizontal, so you make no more mistakes with the different attitudes of the Smartphone with video or picture taking. For rotation, a simple center of gravity shift down or a small electrically movable or tilting weight 62 (can also be a small permanent magnet), which is built directly into the ball digital camera, which always aligns the ball digital camera so that the images are perfectly recorded in a vertical position. If you want to record video as soon as the video mode is turned on, the additional weight is rotated electrically around the optical axis by 90 ° and then you can take video recordings with the video always taken in a horizontal position, even when turning the smartphone in any direction. For the pivoting of the weight body (or the permanent magnet) are one or more electromagnets 35 necessary, which are also installed in the ball camera in it this time. By reversing the polarity of the electromagnets, the weight can be moved 90 ° in one direction or the other ( 45 ).

39 shows a variant wherein the coils are very small and are made with doping or chemical etching processes (eg chemically or by the light). Here on the sketch, the ball camera has been taken out of the ball socket / hollow sphere for a better view. These coils 11 are very small, totally flat, because they are made of very thin wires and have a spiral shape. But they are available in a very large number. This allows you to create an almost punctual magnetic field that the ball digital camera then also put in rotation. A little Point at the back of the optical axis to the spherical digital camera, which has ferromagnetic properties, can serve perfectly for this. This small part is tightened from bobbin to bobbin until the desired position of the bullet digital camera has been reached. The magnetic traveling field is controlled by the controller 21 which removes and builds up the magnetic field from coil to coil by current control.

The 40 shows a smartphone 29 where the ball camera 1 is mounted on the edge or even better on the corner, with a rotation from front to back allows a more than 180 ° image recording. The detection angle can be over 320 °, considering that the camera can also be directed downwards, both front and back (for example, if you hold the smartphone vertical). The placement on the corner allows a perfect rotation and always a clear view of the camera's image sensor.

In the 41 is a variant with piezo elements 51 been presented. Here, the vibrations of the piezoelectric elements as a driving force for the rotation of the ball camera 1 used. They are mounted tangentially to the ball-mounted camera in the ball socket / hollow sphere and easily touch the ball camera, or are mounted so close to the camera that by the air pressure generated by vibrations alone, a rotation of the ball-less camera Of course, in the variant, wherein the piezo elements are to touch the ball, they are with a soft protective cover 32 wrapped (eg made of rubber), or at least protected at the point that touches the ball camera. The piezo elements are arranged in different directions so that, due to their vibrations, whichever of them is active, the ball can rotate in different directions. The vibrations are of a very small amplitude, but because they are generated at high frequency, their power is always sufficient to turn the sphere. Even in the non-contact variant, wherein the piezoelectric elements alone by air pressure during oscillatory phases, a slight torque can be generated, which rotates the ball. A signal generator 66 generates the necessary current signals that control the piezo elements.

A magnetostrictive drive system works the same way. Instead of piezoelectric elements here magnetostrictive elements are installed, which oscillate at a frequency of a current signal and touch the ball tangentially.

The 42 shows a variant, wherein instead of electromagnetic coils, electroactive polymer / plastic elements 37 are installed for the rotation of the ball camera. These elements are able to change their shape under power. They are here preferably designed in the form of coil springs and are coupled at one end to the ball camera and the other end to the hollow sphere wall. You can also have a partial or full gimbal suspension 22 / 23 Install, with their axes of rotation 24 the electroactive plastic coil spring 37 are attached. When the plastic coil spring is electrically energized, the electroactive elements deform, and because they are mounted in a spiral shape, they thus generate in the coil center a torque which causes rotation of the ball camera. Depending on how the current / voltage values are determined during the excitation of the electroactive elements, so is the torque effect. In this way, it is possible any, precisely controlled rotation of the ball camera.

Through very small swings you can even take 3D images with just one camera. First a picture is taken, then the ball camera is only slightly and quickly panned, whereby another picture is taken. The object to be photographed would then have been taken from two different perspectives, albeit with only a few mm displacement, but software support could well create a 3D image afterwards. The same can also be used for video recordings. The bullet camera can be electromagnetically displaced in rapid dithering, with an image captured at each stop position, just prior to reverse motion. The dithering of the ball camera is easily accomplished with an electronic oscillator (eg, an electronic mono or bipolar flip-flop, an electronic multivibrator circuit, or a logic oscillator circuit) that generates an AC signal that is passed to the coils, to create. With software support, it would be possible to separate the images from the left and right stop positions into an overall video, which would then be passed to viewers by conventional 3D image playback methods.
