Description

The invention relates to a device that is equipped with a digital camera, wherein the image sensor and its optical accompanying elements, within the image or video recording device (carrier device), are movable.

The digital camera is mounted in a compact ball-shaped housing and placed in a chamber that is statically built into the carrier device and shaped like a hollow sphere. The ball housing is able to turn in almost any direction within the carrier device controlled quickly and thus also to detect fast moving targets, without the need to, the entire housing of the carrier device in which the digital camera installed is to move. The invention finds application in devices of all kinds, which have an image sensor, such. B. Digital cameras of all kinds (video cameras, digital Kleildildkameras, digital SLR digital cameras), notebook, smartwatch (a kind of wristwatch with PC-like or smartphone functions), tablet PC, as well as webcams, drone cameras, vehicle cameras or security cameras, data glasses, virtual reality Glasses, mobile phone, among other smartphone, endoscopy camera, other medical devices that have a digital camera, etc. The system is able to move or rotate the digital camera sensor and its optics in all these devices and controlled in any direction. Not all of the digital camera's carrier device is moved or rotated, just the image sensor with its optics within the carrier device, almost like a human eye.

In particular, the system is perfectly suited for small devices that have a digital camera, such as a digital camera. Mobile phones (smartphone), tablet PC's, notebooks / netbooks, data glasses, VR glasses (virtual reality glasses), smartwatch, unmanned remote-controlled drones, robots, endoscopes, etc. Almost any tablet PC, notebook or mobile phone / Smartphone today has a built-in digital camera, mostly even two. Two digital cameras are sometimes necessary for one to take pictures of the environment or to make videos, and for the other digital camera to make a video conversation about providers offering such services (eg Facebook, Skype, Tanga or, Viber, X8, Aquila, etc .). 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 electrically rotatable and can take pictures or record video from both the back and front. Especially for small devices, such. As mobile phones (smartphone), aircraft drones, smart glasses, tablet PC, notebooks, the invention is perfectly suitable.

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. As mobile phones, webcams, vehicle cameras, or drone cameras.

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.

Digital camera systems for tablet PC s, notebooks or smartphones are described, 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 coarse, vulnerable and would destroy the aesthetics of the carrier device.

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 in many 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. moreover Here are physical limits set: the further the image sensor moves, the more distorted the image, 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 invention recited in claims 1 to 56 is based on the problem of equipping an image or video recording device having a digital camera with a drive system that allows liquid movements of the digital camera, wherein the digital camera within the carrier device quickly and silently, with the effect almost like a human eye, turns.

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

For the sake of better understanding, in the description and claims, each device having a digital camera is called a carrier device. This can z. B. a video camera, Kleibildkamera, SLR digital camera, notebook, TV, PC screen, smartwatch, tablet PC, webcam, drone, vehicle, aircraft, rocket, robot, surveillance camera, data glasses, mobile phone - among other smartphone, extreme Sports Digital Camera, TV Studio / Cinema Film Digital Camera, SteadyCam, etc.

The invention is any device equipped with a digital camera, wherein the image sensor and its accompanying optical elements are fluidly movable and capable of tracking a target to be photographed, to take a video shot of a mobile object or person, or to achieve an automatic rotation of the image sensor and its optics in order to realize images or video recordings from different viewing angles, preferably from behind and / or from the front (with only one image sensor). An extremely small mobile digital camera system that even in a small digital camera carrier device, especially in a mobile phone (smartphone), tablet PC, webcam, wristwatch, TV, virtual glasses (VR glasses), robots , etc., 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 digital camera is extremely fast, silent, precisely controllable and can move, rotate or even rotate dynamically and quickly within the digital camera-carrier device, allowing video / image capture from different angles, even from the back and front of the camera Carrier device are possible.

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

8th to 45 various types and uses 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 sphere chamber (from now on this is only ball socket or 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 ball-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 a tablet PC, I-PAD, 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 and front. 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 conventionally by gears or electric motors (not manually by touch), but by one or more electromagnetic coils / solenoids 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 hollow sphere simply loose freely inserted therein, which is electromagnetically rotated without contact. The bullet digital camera can but 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 housing and the 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 spherical digital camera 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 Bullet Digital Camera is equipped with a permanent magnet 13 preferably in the center or near the center, or with magnetic areas 15 equipped with these by means of one or more electromagnetic coils / electromagnets 10 in the 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) can be made of finely twisted wires, the z. B. are formed spirally exist. Thus, the power supply and signal pickup from the image sensor of the ball-digital camera and this would hardly affect the rotation of the ball or disturb. The bullet digital camera is powered by the electromagnet, depending on which of the solenoid coils in the hollow sphere 8th is active, in any direction, fast and turned silently. Supported by the software (mainly that of the carrier device), 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. This is similar, just as a person 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 blur, no matter how hard the carrier device is panned back and forth, because the electromagnets can be controlled very quickly. The rotational speed is dependent on the magnetic field intensity of the electromagnets, which in turn is easily controlled by the current intensity conducted thereto. In a mobile phone 29 (Smartphone eg I-Phone) or tablet PC 30 (for example, I-PAD), a continuous hole in the form of a tunnel will be made at the location where the ball digital camera is located 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, one can also install the 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, the hollow sphere would then turn 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.
• – der 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 in addition to electromagnetically in other form and principle:

• - 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.
• - The 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 clear advantages over the prior art. This digital camera is rotated contactlessly via electromagnetic fields within the carrier device, the rotation being instantaneous and silent, which is also optimal for discrete monitoring 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 all the digital camera 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 ( 1 and 2 ). Counter-movements can be used very well to compensate for dithering during video or image capture. The conventional digital cameras use a movable lens for this purpose, which performs very small but very fast panning movements, which act against the dithering, with the focus of the image on the image sensor always remains in the same place, although the digital camera slightly wobble and that with the rhythm of the dithering of the digital camera user. Thus, conventional image stabilizers are usually built. The drive System for the ball camera can very well compensate for such digit 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 means of electromagnets in any direction, much like a rotor in an electric motor ( 1 ). 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 on the outside, which are placed in the hollow sphere at different locations and which are supplied with power by a controller, the ball digital camera is rotated without contact. The more the number and the smaller the electromagnets are built into the 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 bullet digital camera is rotatable within the hollow sphere, it can be used as a rear camera as well as 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 hollow sphere can be built completely transparent, or it can reach certain places with large windows of light 9 equipped, through which the light arrives from the image motifs or environment in the ball-digital camera and its sensor also reached. In a transparent 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 more or less moved out of the carrier device to increase the viewing angle. In the case would be another solenoid coil 10 necessary that the hollow sphere 8th or a hollow cylinder in which the ball digital camera would be mounted, more or less moves out of the carrier device.

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 digital camera's movements. 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 hollow sphere without any bearings. Ideal and easy would be a two-axle 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 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 gimbals, or in variants where the ball digital camera is simply loose in the 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 digital camera can also rotate around the optical axis, it is possible to photograph or create perfect images even when tilting the carrier device. The picture would always be perfectly straight no matter how weird the digital camera is. Using the control unit and, of course, the software support of the carrier device, 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 control can distract the ball-digital camera so that with relatively high frequency (eg several hundreds of Hz), this oscillates back and forth, so that simultaneous picture or video recordings from picture motives are far apart, from different perspectives, very wide Panorama images or images from both the back and from the front of the carrier device are simultaneously possible without the carrier device must be pivoted 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 provides an image from the image motif A, which is located on the right from the perspective of the carrier device, 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 carrier device ( 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 or perspectives. 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 rotated 180 ° while the light axis is panned, the image does not blur because the image sensor turns on and off, or the shutter opens only when the camera is stationary. In the case, it looks like the light-receiving panel is being changed from the front or back ( 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 digital camera-carrier device 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 expansion of the window tip can not extend over the ring, resulting in the formation of the dome. Because the window is already bent slightly outward, an expansion will initiate the dome formation to the outside. In the window-dome, the spherical digital camera can by a solenoid coil 38 driven, slip into it and thereby significantly broaden the viewing angle, which would be interesting, such as when the carrier device (eg 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 can be interrupted to electroactive polymer element and the formed window tip takes 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 digital camera-carrier device 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 digital camera would be aimed 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 (whether magnetized area, permanent magnet body, permanent magnet ring) is made by electromagnetic coils 10 in the wall of the hollow sphere 8th are permanently installed (can also be installed completely outside the hollow sphere), rotated in any direction controlled. 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 64 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 also 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 digital cameras, where a person's face is captured and tracked as soon as it is detected.) In such cases, the autofocus settings are always closely aligned with the subject's face, so that a clear picture is taken becomes.

The rotatable ball digital camera 1 can with a return spring 26 or even better with an additional resting position permanent magnet 48 that has a ferromagnet area 57 or Ferromagnet body (preferably iron or nickel) in a rest position, be equipped ( 12 ). The variant with return spring, a soft and spiral spring should be equipped, which does not prevent the pivoting movement of the ball camera. The method works better with the permanent magnet, which ensures the resting state. It does not prevent the rotation of the ball camera and can allow large swivels. The return actuator spring 26 or the rest position permanent magnet 48 ensure that when the ball digital camera turns electromagnetic, a certain magnetic field force turns the ball to a certain position. By amplifying the magnetic field of the electromagnetic coil, the digital camera continues to be rotated until the magnetic field force or the return spring force is 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 digital camera, you can also use a small Ferromagnet body 16 realize the rotation built into the ball digital camera in one place. 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. However, the variant with the permanent magnets also has some advantages, because it is with few electromagnets and more precisely controllable. When coil 1 is active, the digital camera is rotated in direction A. If the coil 1 is reversed or in addition the coil 2 is activated, then the digital camera rotates in the direction B. The polarity reversal of the coils only shows an effect with variant with the permanent magnets. Depending on how strong the magnetic field of the coil 2 is, the ball digital camera, more or less rotated. But are z. B. simultaneously activates the coils 1 and 3, then the digital 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 is more in the direction of the stronger Coil done. Thus, the digital camera rotated in any direction ( 13 ). An attenuation of the vibrations of the ball digital camera can be achieved electronically by controlling 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 Quickly dampen digital camera. 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 bullet digital camera is vibrating ( 14 ). A digital detection of such induction fluctuations, realizes the vibrations of the ball digital camera in real time. Countermeasure with small current pulses can dampen these vibrations as fast as lightning and bring the ball digital camera to rest. Both for the detection, as well as counter-control can use the same solenoid coils 41 or 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 soft and coupled at one end to either the bullet-camera outer wall or 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, the ball digital 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 hollow sphere. The ball digital camera is slightly smaller than the hollow sphere, thus freely movable in it. The recording direction of the digital camera is through the electromagnetic coils 10 determined, which are installed on the hollow sphere wall. The electrical 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 carrier device (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 hollow sphere is only slightly larger than the ball digital 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 ball digital camera, one can achieve any rotation of the ball digital 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 spherical digital camera. This allows optimal illumination that tracks the movement of the field of view of the ball-digital camera. Also a flash, preferably as a light emitting diode 54 built into the ball digital camera, can be used for 15 ). 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 digital camera in 3D possible, or all on three space axes, although a simplified variant with a partial gimbal 23 with only two axes of rotation 68 , rightly so. The electromagnet system can be extremely fast, absolutely silent and precisely controllable. Digital camera devices that are equipped with it, can quickly detect moving targets and follow. Whether it's for mobile phones, webcams, dashcams, tablet PCs, laptops, televisions, robots, vehicles, surveillance cameras, aerial drones, fighter jets, missiles, or other equipment, it meets all the technical requirements for capture of fast moving targets. The digital camera housing can also be built in 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 digital 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 digital camera carrier device that the digital camera incorporates.

In a variant that in the 19 is shown, the ball-digital camera, in which the digital camera sensor and its optics are mounted, on a spring 25 attached, with side solenoid coils 10 (At least three pieces arranged at 120 ° to each other), are attached, which can attract the ball digital camera in any direction tangentially. By donning the globe digital camera 1 The angle of the digital camera is changed and that in the direction of how the housing is pulled. The feather 25 , to which the ball digital 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 the angle of the tilt of the ball digital 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 swivel direction of the digital 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 hollow sphere also turns 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-digital camera would always be located in the back of the hemisphere and from there they would pivot the ball-digital camera in any direction ( 21 ).

An electrostatic drive can also be well suited for this purpose. This drive would be similar to that of 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 69 (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 digital camera case may not necessarily be, but is optimal in the case. The ball digital 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 digital camera, on the other hand, the variant with the coil spring 25 is very simple and also economically very cheap. Here, behind the ball digital 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 digital camera, or another permanent magnet mounted in the ball digital 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 digital camera, a magnetic field force is the Turn the ball to a certain position. By amplifying the magnetic field of the electromagnetic coil, the digital camera continues to be rotated 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 globe digital 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. When coil 1 is active, the digital camera is rotated in direction A ( 17 ). When coil 2 is activated, the camera will rotate in direction B. Depending on how strong the magnetic field of coil 2 is, the digital camera ball is turned more or less. But are z. B. simultaneously activates the coils 1 and 3, then the digital 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 digital camera rotated in any direction. An attenuation of the vibrations of the ball digital camera can be achieved electronically by controlling the coils, with several hundreds or even thousands of times per second, small impulses are given to the coils, with the aim to quickly dampen the vibrations of the ball digital camera, 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 digital camera is vibrating. A digital detection of such induction fluctuations, realizes the vibrations of the ball digital camera in real time. Countermeasure with small current pulses can dampen these vibrations as fast as lightning and bring the ball digital 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 that houses the digital camera. 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 digital camera sensor 2 not to be restricted even when turning.

The system is able to move the digital camera sensor so fast in real time the ball digital camera, so that 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, the system being constructed as follows: the ball-digital camera (image sensor housing and their 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 momentarily activated, the black dot is attracted so as to come close to a connecting line between the two coils. When the coil 3 is activated, 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 into the globe digital camera 1 is installed. Here, the permanent magnet depends on the magnetic field lines 17 the active coils 10 and thus turns the bullet digital camera 1 , depending on which of the coils is active.

The 24 shows a variant where many coils 10 into the hollow sphere wall 18 are incorporated, which can be activated individually or in groups. With single activation, the permanent magnet is directed 13 into the globe digital camera 1 is built according to the magnetic field lines of the active coil and thus the digital camera turns in the direction. Because the ball digital camera movement 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 digital camera 1 to maintain their freedom of movement in two axes. This does not obstruct the digital camera's view.

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 digital camera. The ferromagnetic region 57 Can be applied as a thin coating on the ball digital 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 digital camera back and forth.

In the 26 The globe digital 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 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) or tablet PC 30 is installed. The IPAD digital camera or I-phone or smartphone or mobile phone digital camera, can be installed so that it is rotatable inside it and is suitable for both rear and front. Because the digital camera only moves from the inside, the carrier device also looks very good aesthetically. The digital 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 at least in one area and the digital camera by an electromagnet 10 is rotatable. The rotation takes place in one or more axes. Multi-axis rotation can also be achieved by loose placement 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.

You can also install in a tablet PC or smartphone a simplistic mini-gimbal in which the ball-digital camera is attached and thus in any direction in three axes is pivotal. Face or person tracking can be easily realized because the digital camera could track the face through its rotation. In order to take pictures to the rear, the smartphone or tablet PC / iPad should then have a continuous hole / bore or tunnel in the place in which the digital camera is installed, so that when the digital camera is facing backwards or forwards , has a clear view.

The hollow sphere that forms the cage housing for the bullet digital camera in a smartphone is only slightly larger than the bullet digital camera itself and has several electromagnetic coils. Due to the magnetic field interaction between the fields of the electromagnetic coils of the housing and the permanent magnet of the ball-digital camera, a precise controlled pivoting will be achieved. Of course, instead of the permanent magnet, it is also possible to install solenoid coils in the ball-digital camera, but then one would also have to ensure the power supply of these coils, which would indeed be achievable by means of flexible cables, but the effort would be greater. The installation of electromagnetic coils in moving parts is not absolutely necessary because a permanent magnet can do its job very well. Using permanent magnets that are very small and sophisticated mounted on the ball digital 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 digital camera and moved with the image sensors and its optics. This allows for optimal lighting that the Tracked movement of the image sensors. Also, a flash, in the case because of the small size of the image sensors, preferably as light emitting diodes 54 built-in, can be used for 5 or 15 ).

The drive for the digital camera from a tablet PC, drone, webcam, or smartphone (generally mobile phones), can be designed so that gradually or completely from front to back the ball camera is electrically controlled rotated, which is absolutely noiseless, contactless 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 the video recording signals 25 times from the back and 25 times from the beginning and thus per second 25 take full pictures of one page and just as much from the other side of the phone. Even fast panoramic images or 360 ° images / videos would be easily feasible with this device. The horizontal tilt of the digital camera would be just as fast as the vertical. The ball digital 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 digital camera and is quite sufficient to dampen the vibrations that arise during the electromagnetic positioning. Without the damper, the digital camera would swing back and forth at least a few times, possibly creating unclear images. Also the previously mentioned bristles 63 or a few very small sponge bodies 64 do the job very well. The ball camera is thus stopped immediately, as soon as the electromagnet / solenoid coil inactive and their magnetic fields are reduced. With corresponding software or app (application, software application) you can make fast pictures from different perspectives. The speed at which the ball-digital camera moves is extremely high. This also makes it possible to track the fast-moving targets. Also the braking of the ball digital camera succeed quite fast (can be initiated automatically by release button), so that crystal-clear single-image recordings are possible.

For 3D image capture, two such digital 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 digital camera will be installed like an eye of a human in a 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 digital camera can be designed to be easily lifted out of the cellphone or tablet PC electromagnetically or electrically, so it will look a bit out if the device stays somewhere ( 29 ). The cover lens or dome 27 or a transparent hollow cylinder 58 in which the digital 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 lying, is lifted, or the digital camera moves forward or backward. 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 36 is poled. The dome-shaped ends, of course, are transparent and each form a window through which the digital 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 digital camera 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 that directs the digital camera directly where the sound source is located (the digital camera "looks in the direction of the sound source"). That would be handy if you record videos and the recorded person also speaks. The digital camera would automatically track the sound source in this case.

The tracking of fast objects can be supported by the software of the carrier device. On the control screen of the carrier device, one can mark an object by finger-touch and that would then always automatically track the digital camera, no matter how it moves or how the digital camera-carrier device 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 achieved, the dome-shaped plastic part will flex flat again and thus detach from the sensor.

In one variant, even an electrically bendable polymer or plastic part can always remain coupled to the image sensor in order to actively design the optical properties of the image sensor. In that case, the image sensor would be flexible and could sometimes be more or less electrically controlled by a controller built into the camera. In particular, this feature would be important when using different lenses / telephoto lenses in a camera. The electrically deformable polymer 70 is directly coupled to the back surface of the image sensor and by a special controller 71 controlled, can control the degree of bending of the image sensor ( 44 ). The manufacturer can make the bending values of the image sensor depending on the optical elements used, which is realized by automatic interchangeable lens recognition features.

On the 32 a variant has been shown, wherein the stopping of the ball-digital 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. Stopping is also done electromagnetically, it can either by a small pin, which is moved out electromagnetically from the hollow-sphere wall in the direction of the ball-digital camera and then touched on the 33 a variant has been shown, wherein the stopping of the ball-digital camera by simply pulling (electromagnetically) on the hollow sphere wall surface, wherein it touches the wall, takes place.

Also prove to be small electrically brakable ball bearings, the permanent magnet micro-spheres 42 exist between the hollow sphere housing and the ball digital 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. Although the control coil does not have to, it can have a ferromagnetic core 44 with a small tip, in which the magnetic field is built up concentrated. Once the electromagnetic control coil is activated, it will affect the movement of the micro-sphere and prevent it from rotating further. Thus, the ball digital 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 digital 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 can be braked by electromagnetic control, the others can be simple inactive plastic beads which form a kind of warehouse in which the ball camera glides smoothly.

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

The spherical digital camera does not necessarily 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-digital camera, with several individually or in groups controllable solenoid coils 10 built very narrow and ring-shaped, include the hollow sphere and are installed several times, which are similar to earth meridians arranged in the field of view of the ball digital camera but missing. The electromagnetic coils overlap at least at two points. The imaginary line connecting these two points forms the axis of rotation of the spherical digital camera. In order to realize another axis of rotation around which the ball-digital 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 digital camera, which has a permanent magnet in it, to align their magnetic field lines. To achieve a smooth and precise rotation of the ball-digital camera, by activating and deactivating the coils in order, a traveling magnetic field is generated which rotates the ball-digital 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-digital 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 digital 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 ).

On the 38 (a, b, c, d, e) a few examples of use of the invention are shown.

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 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 small dot on the back of the optical axis to the spherical digital camera, which has ferromagnetic properties, can serve perfectly. This small part is attracted from bobbin to bobbin until the desired position of the bullet digital camera has been achieved. 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 digital 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 digital camera can also be directed obliquely downwards, both front and back (for example, if the smartphone is held vertically). 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 arranged tangentially swinging to the ball-mounted camera in the hollow sphere and easily touch the ball-camera, or are attached so close to the camera, that alone by the generated air pressure by oscillations, a rotation of the ball-camera takes place without contact. Of course, in the variant where the piezo elements are to touch the ball, they are with a soft protective cover 66 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 67 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 digital camera. These elements are able to change their shape under current, or length or dimensions. They are here preferably designed in the form of coil springs and coupled at one end to the ball-digital camera and at the other end to the hollow sphere wall. You can also use a gimbal suspension 22 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, being mounted in a spiral shape, thus generate in the coil center a torque which causes rotation of the ball digital 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 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.
