Description

[0001] The invention relates to a sighting device with a telescopic sight and an attachment, as well as a method for adjusting a sighting device.

[0002] The conjunction “and / or” is to be understood here and in the following in particular in such a way that the features linked by means of this conjunction can be formed both together and as alternatives to one another.

[0003] A long-range optical device within the meaning of the invention is a device capable of displaying an object located at a distance significantly greater than an arm's length, preferably significantly greater than one meter, from an observer, larger than the observer would see it from the same vantage point without the long-range optical device. Such a long-range optical device can, for example, be from the group of riflescopes, monoculars, telescopes, spotting scopes, binoculars, and cameras with telephoto lenses, but is not limited to this.

[0004] Although the use of a hunting or sporting riflescope is particularly well suited for the purpose of the invention as an example of a long-range optical device, the invention is equally applicable to the use of any other conceivable long-range optical device. The invention explicitly encompasses the use of the inventive features of all embodiments in all conceivable long-range optical devices, even if the invention is explained below using hunting riflescopes.

[0005] For the accurate use of hunting or sporting handguns, special long-range optical devices, so-called telescopic sights, are often used. Such telescopic sights are mechanically connected to the hunting or sporting handgun, so that when looking through the telescopic sight, the user is looking in the direction in which a projectile travels after a shot from the handgun is fired.

[0006] The term "handgun" here includes, in particular, hunting weapons, but also all sporting weapons, as well as other firearms. This includes, in particular, rifles, but also other weapons such as automatic and semi-automatic rifles, pistols, submachine guns, and the like.

[0007] Long-range optical devices, especially rifle scopes, often have an optical structure comprising at least two optical groups. A first optical group forms a so-called rifle scope objective, through which light coming from the object is projected into a first real image in an objective-side image plane. A second optical group, here called the rifle scope eyepiece, serves to enable a user to observe the first real image or another real image of it. For this purpose, the first real image of the object or another real image of it is projected through the rifle scope eyepiece into a great distance, preferably into infinity. The eyepiece is positioned so that the eyepiece-side image plane coincides with the objective-side image plane or another conjugate image plane, or is at least very close to it, so that an image is created into infinity or into a distant plane.

[0008] Riflescopes very often also have at least one additional optical group, a so-called "reversing system." The reversing system has at least one optically active component such as a lens and / or a prism, but preferably several optically active components. The reversing system is often arranged between the riflescope objective and the riflescope eyepiece. It serves to project the image from the objective-side image plane onto another plane within the riflescope, thereby optically reversing it. The riflescope eyepiece is then arranged such that it projects the image plane of the reversing system to infinity. This can ensure that the image observed by the user is upright, whereas without the reversing system it would be "upside down."Often, the riflescope objective lens and riflescope eyepiece are arranged in such a way that their respective optical axes are located on the central axis of a tube, here called the “outer tube”.

[0009] The optical groups riflescope-objective and riflescope-eyepiece are optically characterized, among other things, by the respective focal length f Objektiv or f Okular For a simple long-range optical device, for example a simple riflescope, which consists only of these two groups, the optical magnification is then given by V=f Objektiv / f Okular . If a long-range optical device also includes an inversion system with a magnification of β Umkehrsystem , the total magnification is given by V=fLens*|βInverting system| / fEyepiece.

[0010] Riflescopes often have the ability to continuously adjust the optical power of one of the optical groups, thereby achieving a continuous change in the optical magnification provided by the riflescope. Such optical groups are referred to as "pancratic" groups or "zoom" groups, or generally as a "zoom system." The optical group of the reversing system is often designed as such a zoom group, but it is also conceivable that they are separate optical groups.

[0011] Riflescopes with variable magnification are often designed so that the image planes of the riflescope objective and eyepiece are at a fixed distance from each other and remain at this distance even when the magnification is changed. In this case, the zoom system is designed to project the real image from the image plane of the riflescope objective into the image plane of the riflescope eyepiece, whereby the image scale of the image can be changed.

[0012] Preferred magnification ranges for hunting riflescopes are in the low range, for example, in the range from 1.1x magnification to 8x magnification, as in the ZEISS V8 1.1-8x24 riflescope. In the higher range, preferred magnifications are, for example, in the range from 4.8x magnification to 35x magnification, as in the ZEISS V8 4.8-35x60 riflescope. These magnifications and magnification ranges are, of course, only examples and should not be understood as limiting. The method according to the invention can also be applied to riflescopes with other magnifications and magnification ranges.

[0013] Riflescopes often have an aiming mark, known as a reticle. This is a marking, such as a crosshair or a ring. A reticle is arranged in the optics in a true image plane so that the user can observe both the object and the reticle sharply at the same time, with the reticle superimposed on the object. The reticle is usually arranged either in the objective-side image plane or in the eyepiece-side image plane. The reticle serves the purpose of enabling the user to aim. Ideally, the reticle is adjusted so that the reticle marks the point of impact of the projectile when the user looks through the riflescope.

[0014] Often, the relative spatial relationship between the reticle and a real intermediate image can be shifted in two dimensions using a mechanism. In particular, a horizontal shift and, independently of this, a vertical shift are often provided. This causes the image of the observed object to be shifted relative to the reticle. The reticle and inversion system are often mounted in an inner tube, which is located within the outer tube and can be shifted and / or tilted relative to it. This allows a real intermediate image of an object to be shifted laterally relative to the reticle.

[0015] A projectile fired from a hunting or sporting weapon does not follow a straight line, but rather follows a ballistic trajectory due to gravity. This trajectory is also affected by other external influences, such as wind. By shifting the real intermediate image of an object relative to the reticle by operating the mechanism, the riflescope can be adjusted so that the reticle overlays the image of the projectile's point of impact.

[0016] Riflescopes are preferably purely optical devices, but it is also conceivable to implement part of the image transmission path electronically. For this purpose, for example, an image pickup or sensor can be arranged in the image plane of the objective lens, which can generate an electronic image of the real image. This electronic image can be displayed on an image generator, a screen, or a display located in the image plane of the eyepiece. With such an arrangement, it is particularly possible to perform image inversion, variable magnification, and / or the insertion of a reticle electronically.

[0017] The invention is therefore expressly not limited to an application in purely optical long-range optical devices, but also includes the application in those which include electronic image transmission.

[0018] An attachment within the meaning of the invention is, for example but not exclusively, a thermal imaging device or a residual light intensifier or a comparable device that is particularly suitable for observing poorly visible objects with modified and / or improved contrast and / or increased brightness. For example, a thermal imaging device can convert different heat levels of an object into a visible brightness contrast and / or a visible color contrast. This can be achieved by detecting the long-wave radiation emitted by the object being observed. This radiation is often in the infrared range of the electromagnetic spectrum, which is invisible to the human eye.

[0019] A low-light intensifier at least increases the brightness when observing an object, but can also increase and / or change the contrast. With such a device, at least a portion of the observed light typically lies in the range of the electromagnetic spectrum visible to the eye. A low-light intensifier, in particular, but also another attachment, can fundamentally correspond in design to a long-range optical device with an electronic image transmission link, or at least be similar to it, as explained above. The invention therefore particularly encompasses, but is not limited to, the use of a combination of two long-range optical devices with an electronic image transmission link.

[0020] An attachment according to the invention comprises an "attachment lens" which images light of a suitable wavelength range onto an electronic image recorder, referred to here as an "attachment sensor." The attachment lens typically contains one or more optically active elements, frequently optical lenses. For imaging long-wave infrared light, the lenses are often made at least predominantly of germanium or chalcogenide. The attachment generates an optical image which can be recorded with the attachment sensor, frequently but not exclusively of the "bolometer" type. The attachment sensors used frequently contain amorphous silicon and / or vanadium oxide. The attachment sensor is suitable for generating a first sequence of digital images which can be processed and modified using a data processing unit. The resulting, possibly modified images form a second sequence of digital images.

[0021] For example, the data processing unit can increase the visual contrast compared to the first sequence of images. To do this, the data processing unit can execute one or more data processing algorithms in the form of computer program code. The visibility of details in the recorded image sequence is often increased by the processing of the data by the data agreement unit. The second sequence of digital images can, in particular, be generated taking certain color modes into account. It is possible to use algorithms that incorporate a type of automatic exposure control, in the sense that the individual images are modified in such a way that they are adapted to changing environmental conditions, such as ambient temperature.

[0022] The second sequence of digital images is displayed on an electronic imager or screen, referred to here as the "attachment display." The overall brightness of such an attachment display can often be adjusted by the user, particularly to accommodate ambient brightness. A "attachment eyepiece" is arranged downstream of the attachment display in the optical path, through which the image displayed on the attachment display can be viewed by an observer. The "attachment eyepiece" can be optically constructed to resemble a commonly used eyepiece for visual observation, but can also, preferably, be constructed to resemble a collimator.For the sake of clarity, the term "attachable eyepiece" is used here, but it is intended to encompass all optical groups capable of converting light from a real image and / or an object into a parallel beam path and / or projecting it at a long distance. A "parallel beam path" is understood here and below as one in which the light from a focused object point is converted into a parallel or nearly parallel light beam.

[0023] The magnification of an attachment is often at or close to 1x. This makes it possible to achieve a geometric visual impression when viewing an image on the attachment's display through the riflescope that approximately corresponds to the geometric visual impression when viewing the same object without the attachment, because the total magnification of a sighting device in the sense of the invention results precisely from the product of the magnifications of the attachment and riflescope components.

[0024] Since an attachment is an electronic device, it often has displays for operating parameters or other information. These can include magnification, distance, angle, level indicator, battery charge level, operating mode, display profile, selected contrast setting, connectivity indicator (e.g. for Bluetooth) and / or similar information. This information can be text, graphical information or even icons. This information is often shown in a peripheral area of ​​the attachment display to keep the central area of ​​the attachment display free for observing the objects to be observed.

[0025] To control an attachment, there are often operating elements on the attachment, for example one or more control knobs, one or more buttons, one or more switches, one or more control wheels and / or one or more other operating elements.

[0026] A long-range optical device and an attachment are often similar in terms of their optical design in that both have a lens capable of projecting distant objects, up to "infinity," into a lens image plane. Furthermore, both have an eyepiece capable of projecting an image plane into a distant virtual image, up to "infinity" away.

[0027] It is known to arrange attachments in front of riflescopes or other long-range optical devices such that they are optically aligned, and the optical axis of the eyepiece of the attachment and the optical axis of the riflescope objective coincide, or at least approximately coincide. Then, the parallel output beam path of the eyepiece of the attachment and the parallel input beam path of the riflescope objective coincide, and the images displayed on the display of the attachment can be observed by the user via the riflescope. Such a combination, called a "sighting device," of a riflescope and attachment is known, for example, from DE 10 2004 047 576 A1.

[0028] For optimal interaction between the attachment and riflescope, it is advantageous if the exit pupil of the attachment's eyepiece coincides with the entrance pupil of the riflescope's objective. This has been shown to achieve advantages such as minimal vignetting, maximum light output, and / or a maximum field of view.

[0029] For optimal interaction between the attachment and the rifle scope, it is also advantageous if the magnification of the attachment is approximately 1x, because then the magnification of the rifle scope when using the attachment corresponds exactly to the magnification of the direct view of the object through the rifle scope without the attachment.

[0030] Attachments are known that are suitable for being mounted in front of a riflescope and mechanically secured. In other words, the long-range optical device that sees "infinity" can be optically arranged in series behind the eyepiece of the attachment that images "infinity," so that the display of the attachment can be observed with the long-range optical device.

[0031] Many long-range optical devices offer the option of adjusting the magnification, known as "zooming." This is particularly the case with many hunting riflescopes. If the riflescope is mounted in line behind the attachment, as described, changing the riflescope's magnification will result in a different area of ​​the attachment display being observed depending on the riflescope's magnification. The following applies: the higher the magnification, the smaller the observable screen area. For example, if in one configuration with a riflescope magnification of 1.1x the entire attachment display is observable, at a magnification of 2.2x only a portion of the attachment display is observable. At a magnification of 4.4x, only half the area of ​​the attachment display is observable compared to 2.2x magnification.In other words, at double magnification, an image section with half the width and half the height, i.e., a quarter of the area, is observable. For other configurations and magnifications, the observable sections of the attachment display are different in detail, although the basic principle remains the same.

[0032] Because the attachment and the riflescope or other long-range optical device are optically coupled by an at least approximately parallel beam path, the focus of the long-range optical device remains intact when zooming, and only the observable section of the attachment display changes as described. Since a smaller portion of the attachment display is imaged when selecting a higher magnification of the riflescope, this appears to an observer as if a narrower image section is being observed with the entire observation device. The effect of zooming is thus identical to the effect of zooming without an attachment: the higher the magnification, the smaller the observed area and the larger the representation of the observed area.

[0033] If the mechanical attachment of the attachment to the riflescope is not absolutely precise, the optical axis of the riflescope and the optical axis of the attachment's eyepiece may diverge, resulting in the display center point not being observed on the optical axis of the long-range optical device. It is also possible that, for example, due to manufacturing tolerances, the display center point is not aligned with the eyepiece's optical axis. In this case, the display center point is usually not aligned with the riflescope's optical axis. It is also possible that the display center point of the attachment's sensor is not aligned with the optical axis of the attachment's lens. This means that the optical axes of the riflescope and the attachment's lens may diverge. In all of these cases, the scene observed with an attachment will shift compared to when observed without an attachment.

[0034] Depending on the magnification and adjustment, a different area of ​​the attachment display can be observed. This can result in certain information being displayed on the screen, for example but not exclusively at least one of the icons, symbols, status displays and / or system parameters, but this information cannot be observed by the user because the section of the screen visible through the riflescope is too small and / or is in the wrong place. In other words, it can happen that the information displayed is outside the currently observable section of the attachment display. This problem occurs particularly frequently for information such as icons, status displays, menu items and / or one or more other similar pieces of information, since this type of information in particular is often intended to be displayed in a peripheral zone of the riflescope's field of view.

[0035] US 2014 / 0110483 A1 discloses a sighting device consisting of a thermal imaging device and a telescopic sight. However, no method for adjusting the sighting device to different magnification levels of the telescopic sight is described.

[0036] DE 10 2019 132 858 A1 discloses connecting a thermal imaging device to a riflescope. While it explains that the information displayed on the thermal imaging device's screen can be adjusted to the area observed by the riflescope, it does not describe a method for adjusting the display to different magnification levels of the riflescope.

[0037] US 2016 / 0356573 A1 discloses connecting a riflescope to an additional device, such as a laser rangefinder, and enabling wireless communication between these devices. However, no sighting device with a thermal imaging device is described, and no method is shown for adjusting such a sighting device to different magnification levels. Other known systems, such as the one described in DE 10 2004 047 576 A1, also do not provide a solution for overcoming the described disadvantages of the prior art.

[0038] Therefore, the primary object of the invention is to provide a method which avoids the described disadvantage by making it possible to adjust the attachment in such a way that continuous observation of such information is ensured, regardless of the magnification setting of the riflescope.

[0039] The object is achieved by the features of claim 1. The subclaims dependent on claim 1 describe advantageous developments of the method according to the invention.

[0040] It is a further object of the invention to provide a device which is suitable for carrying out the method for solving the primary problem and in which the described disadvantage is avoided that information displayed on the screen of the attachment device cannot be observed through the telescopic sight because it lies outside the observable section of the screen.

[0041] This object is achieved by the features of independent claim 12. The claims dependent on claim 12 describe advantageous developments of the device according to the invention.

[0042] Due to the rotationally symmetrical design of optical systems common in long-range optics, which also applies to conventional riflescopes, it is assumed below that a circular field of view is observed with a long-range optical device, in particular a riflescope. The explanation of the invention and the exemplary embodiments therefore refer to such optics with a rotationally symmetrical arrangement and a circular field of view. However, the invention can be applied to any other form of optical observation device, for example, to long-range optical devices with a rectangular or oval field of view. The inventive solution therefore includes such other geometries.

[0043] A "circular marking" within the meaning of the invention represents a plurality of display elements displayed on a screen, in particular an "attachment display," which are suitable for allowing a user to recognize an at least largely circular structure "all around" a center. In other words, the surrounding structure encloses this center. The circular structure can, for example, be a solid circle, a segment of a circle, a regularly or irregularly dashed circle, or a regularly or irregularly dotted circle consisting of at least three dots. Instead of the dots, other small, arbitrarily shaped display structures are also conceivable.In principle, any displayed arrangement of arbitrarily shaped display structures that are arranged essentially around a center, preferably rotationally symmetrically, and / or any other geometric arrangement of display structures that is suitable for allowing an observer to recognize an underlying circular arrangement or a circular boundary is suitable. The individual display structures can differ from one another. These can also be icons, symbols, letters, digits, numbers, and / or menu items. An analogous arrangement of the display structures can also be found for target geometries other than circular ones.

[0044] Such a circular marker can be displayed on an attachment display at a predefined position. The circular marker has a center corresponding to the center point of the circle to be indicated or displayed, as well as a display size corresponding to the radius of the circle to be indicated or displayed. The display of such circular markers represents an adjustment aid in the method according to the invention. In other words, the circle indicated or displayed by such a circular marker runs around a center. It goes without saying that this center does not necessarily have to lie within a polygon formed by the individual display elements of the circular marker; it is entirely sufficient for the center to lie within the indicated or displayed circle itself.For example, the center of a circle indicated by a dotted third of a circle does not lie within the "pie-shaped" polygon formed by the points of such a circle marking. Nevertheless, such an arrangement of individual display elements on a third of a circle makes the indicated circle unmistakably recognizable to an observer.

[0045] In the event that the circular arrangement is not observed centered with the telescopic sight, or at least it cannot be assumed that such a centered observation is taking place, at least three displayed display structures are preferred, particularly preferably more than three displayed display structures. If it is ensured that the circular arrangement is observed centered with the telescopic sight, at least a single displayed display structure is sufficient to clearly define the circle. In this case, the center marking is preferably also displayed. However, in this case too, more than one display structure of the circular marking is preferably displayed, particularly preferably three or more display structures of the circular marking are displayed.

[0046] To perform the adjustment method according to the invention, the riflescope should initially be in or at least close to its lowest magnification position to allow observation of the largest possible image section of the attachment display. The adjustment method is activated by the user, for example, by pressing a button, control knob, switch, or similar device, or by selecting a menu item on the attachment. This initiates the method according to the invention.

[0047] In a first step according to the invention, the attachment can display a center marker on the attachment display. Any screen display suitable for marking a position, referred to here as the "center position," on a screen in such a way that the position and / or its immediate surroundings are recognizable to a viewer of the screen is possible as such a center marker. This can be, for example, one or a few pixels located close to one another, a circle, preferably with a small radius, a cross, a star, and / or any other geometric figure suitable for prominently highlighting a position on a screen.According to the invention, as part of the first step, the attachment switches to a first interaction mode such that the actuation of one or more specific operating elements on the attachment leads to a shift of the center marking in one or two dimensions, whereby different positions are highlighted on the attachment display. In this case, a shift can preferably take place in the horizontal direction and / or preferably a shift in the vertical direction, whereby shifts in all other directions are of course also included according to the invention. A suitable operating element is preferably one from the group of control buttons, buttons, switches, rotary wheels, joysticks and / or touchpads, but all other conceivable operating elements such as voice recognition are also included.Also included is that operating elements are designed in such a way that they are displayed and operable by means of a program and / or an “app” on a mobile digital device, for example a mobile phone, a tablet, a laptop, a remote control or a similar device, and the interaction commands are transmitted from the mobile digital device to the attachment display via an interface, for example a cable, Bluetooth, WLAN or a similar data transmission option.

[0048] In other words, the operation of control elements on the attachment itself or on a digital device with subsequent transmission of the information to the attachment is generally to be regarded as equivalent and should be understood in this text as the operation of control elements.

[0049] The displacement of the center marker in the first interaction mode can be made possible in two dimensions, preferably in the horizontal and vertical direction. In other words, a displacement can be carried out independently in two dimensions as desired. However, a division into two phases is also conceivable, with a displacement in one dimension being possible in the first phase and a displacement in a different dimension being possible in a second phase. It is also possible to run through the two phases several times in succession to enable even more precise adjustment. The individual phases or even the first interaction mode can be ended using a control element of the type mentioned above. According to the invention, the first interaction mode can also be ended automatically by the attachment device automatically ending this mode after a certain period of time without user interaction.Preferably, the length of this time period can be adjusted by the user in the configuration of the attachment.

[0050] In any case, according to the invention, ending the first interaction mode results in the storage of position information about the new position of the center marker, i.e., the new center position, in a non-volatile memory. After the position information has been stored, the first step according to the invention ends.

[0051] The described first step according to the invention allows the user of the attachment to optically overlap the center position of the center mark with the reticle of the riflescope attached to the attachment. The position information obtained in this way regarding the center position of the center mark can be used to enable information to be displayed on the attachment display centered on the view through the riflescope. For this purpose, the last center position can be stored in a volatile or non-volatile memory in the attachment.

[0052] In a second step according to the invention, the attachment displays a circular marking of the type described above such that it is arranged all the way around the last center position of the center marking. For example, the circular marking can be centered around the center position by the display structures of the circular marking being at a substantially equal distance from the center position of the center marking. If the circular marking is indicated by only a single display structure, the distance of the display structure from the center position of the center marking corresponds to the radius of the circular marking, which is arranged all the way around the center position with the radius of the distance between the center marking and the individual display structure. The circular marking can preferably be initially selected to be large enough that it can be easily recognized by the observer.The center marking from the first step can remain displayed, but can optionally also be hidden. According to the invention, the attachment switches to a second interaction mode such that the actuation of one or more operating elements leads to a change in the size of the circular marking. In other words, the actuation of one or more operating elements on the attachment results in the distance of the display structures of the circular marking from the center position of the center marking changing. Preferably, the size is changed equally in two dimensions. Mathematically, this corresponds to a centric stretching, with the center position of the center marking being preferred as the stretching center. However, the invention also includes a change in only one dimension, which leads to a deformation of the circular marking. For example, the circular marking can be linearly deformed into an elliptical shape in one dimension.When resizing, the display structures and / or lines of the circle marker may preferably retain their own symbol size and / or line thickness, but it is also conceivable that their symbol size and / or line thickness scales accordingly.

[0053] A suitable control element is preferably one from the group of buttons, keys, switches, rotary wheels, joysticks and / or touchpads, but other control elements such as voice recognition are also included.

[0054] According to the invention, an enlargement of the circle marking is effected by one operating element and a reduction of the circle marking is effected by another operating element. It is also encompassed that a different operation of an operating element optionally causes an enlargement or a reduction of the circle marking. Examples of this can be a single or double button press, or a short or long button press. It is also encompassed that the repeated actuation of a single operating element causes a multiple, step-by-step change in the size of the circle marking in one direction up to an extreme value. After the extreme value is reached, a further actuation of the operating element can cause a sudden, one-off change in size in the other direction.In other words, this operating mode results in a gradual, cyclical switching of the size of the circle marking through a predetermined number of size steps. A change in the switching direction can be achieved, for example, by pressing and holding a control element. All of these described operating concepts are purely exemplary and should not be considered exhaustive. Other – sometimes similar – operating concepts can be imagined that lead to the same result and are also intended to be encompassed by the invention.

[0055] The second interaction mode can be ended by activating a control element of the type mentioned above. According to the invention, the second interaction mode can also be ended automatically by the device automatically ending this mode after a certain period of time without user interaction. This time period can preferably be set by the user in the configuration of the attachment.

[0056] Ending the second interaction mode always results in the acquired size information being saved in non-volatile memory. The display of the attachment can be adjusted at this point according to the saved display information, namely position information and size information.

[0057] The described second step according to the invention allows the user of the attachment to adjust the size of the circular marking so that it is just barely visible at a previously set magnification level of the riflescope connected to the attachment. The size information obtained in this way regarding the size of the circular marking correlates directly with the size of the display area observable through the riflescope. This can be used to display overlays, such as icons, at positions within the size of the circular marking, so that they can be recognized during normal operation of the attachment at the selected magnification of the riflescope.

[0058] According to the invention, the first and / or second steps according to the invention can optionally be followed by a third step in which the attachment switches to an interaction mode that allows the obtained values ​​of the center position of the center marking and the size of the circle marking to be saved in a non-volatile memory. This ensures that the obtained display information from the position information and size information is available again for later use of the attachment. In a simple embodiment, only these values ​​can be saved in the non-volatile memory. In this case, the display of the attachment can preferably be adjusted directly. In a more complex, particularly preferred embodiment, the values ​​can be saved in one of several "profile memory locations" of the non-volatile memory.It is possible for the display information to be stored as a "profile" in an assigned profile memory location alongside other similar display information of other "profiles" in other correspondingly assigned profile memory locations in the non-volatile memory, so that the user has the option of storing position information on center positions and size information for several magnification levels of the riflescope and / or for several riflescopes and retrieving them at a later time.

[0059] Preferably, at least three pieces of numerical information are stored per profile memory location. These can include, for example, a horizontal and a vertical coordinate of the center position of the center marker as position information, and a radius of a circular marker as size information. Of course, any other equivalent numerical information is conceivable for storage, which essentially carries the same information or supplements it. In other words, the invention encompasses all combinations of numerical data from which the required sizes can be derived using mathematical operations.

[0060] The display information can preferably be stored in so-called flash memories as non-volatile memory. This can be a storage medium permanently integrated into the attachment, but it is also conceivable for the storage medium to be removable, for example in the form of an SD card or a USB stick or a similar medium. It is also conceivable for the display information to be stored on an external medium, such as a mobile phone, and to be retrieved from the attachment when needed via a suitable wired interface, for example but not limited to USB or Thunderbolt, or via a wireless interface, for example but not limited to Bluetooth or WLAN.

[0061] According to the invention, a riflescope can be equipped with a sensor, here called a "zoom sensor", which converts the magnification set by the user into an electrical, digital, or similar signal. The zoom sensor can, for example, comprise a potentiometer, a rotary encoder, or a similar component. The zoom sensor can contain a controller suitable for converting the physical measured value into digital or similar information. This zoom information generated by the zoom sensor, here called zoom information, can be transmitted to the attachment via an interface. This can be achieved by electrical contact, for example a plug-socket combination or pin contact in the area of ​​the mechanical interface between the riflescope and the attachment. Another possible data transmission option is wireless data transmission, for example, but not limited to, via Bluetooth or WLAN.For this purpose, the riflescope can be equipped with a radio unit, a transmitter, and the attachment with another radio unit, a receiver. It is also conceivable and preferred for the riflescope and attachment to each be equipped with a radio unit capable of both transmitting and receiving.

[0062] According to the invention, the attachment can select a suitable profile based on the zoom information transmitted from the riflescope to the attachment via the zoom position and adjust the attachment's display accordingly. For example, with a zoom position for 3x magnification, a profile can be selected that is at least approximately twice the size of the displayed area of ​​the attachment display compared to the riflescope setting for 6x magnification. In other words, in this example, a profile is selected in which the previously determined radius of the circular marking for 3x magnification of the riflescope is at least approximately twice as large as the radius of the circular marking of the best-fitting profile for 6x magnification.

[0063] When adjusting the magnification, the currently set magnification of the riflescope, determined by the zoom sensor, can be transmitted to the attachment via the designated data interface. A processing unit in the attachment can then compare the set magnification with the stored profiles. If one of the profiles stored in a profile memory matches the set magnification, this profile can be selected and the attachment display can be adjusted accordingly, so that any information and / or icons that may be displayed are shown in the area of ​​the attachment display that can be seen by the riflescope at the set magnification.

[0064] Alternatively, by executing an algorithm in the attachment, a mathematical correlation can be generated from at least two stored profiles, each containing a magnification of the riflescope. This correlation can be, for example, but not exclusively, a linear or quadratic function or another polynomial. Using this correlation, the attachment can quasi-continuously determine an ideal size for a circular marker for any magnification setting of the riflescope and adjust the size of the display used so that the information and / or icons and / or similar information to be displayed are always within the area observable with the riflescope.

[0065] Alternatively or additionally, in a further embodiment, profile memory locations in the non-volatile memory can be pre-populated with display information corresponding to known magnifications of known riflescopes. Such information can also be transmitted from a mobile device, preferably via wireless communication, to the attachment, thus pre-populating one or more profile memory locations with display information.

[0066] The invention is explained in more detail with reference to the figures. The figures show: Fig. 1 a rifle scope in side view Fig. 2 a sectional image through a riflescope with fixed magnification Fig. 3a a sectional image through a riflescope with variable magnification in a first zoom position Fig. 3b a sectional image through a riflescope with variable magnification in a second zoom position Fig. 4 a sectional view of a sighting device consisting of an attachment and a telescopic sight Fig. 5a a sectional view through a sighting device consisting of an attachment and a telescopic sight with variable magnification in a first zoom position Fig. 5b a sectional view through a sighting device consisting of an attachment and a telescopic sight with variable magnification in a second zoom position Fig. 5c a cross-sectional view of a sighting device with wireless communication Fig. 6 examples of different observed fields of view due to different magnifications of the riflescope Fig. 7a Examples of center markings Fig. 7b Example of shifting the center mark Fig. 8 examples of circle markings

[0067] Fig. Figure 1 shows an example side view of a riflescope 1. The riflescope has one or more rotary adjustment knobs, for example, a reticle adjustment 12 and / or a focus adjustment 13. The focus adjustment is often referred to as "parallax compensation." The focus adjustment moves a focusing lens 15.

[0068] Fig. 2 shows an exemplary sectional image through a riflescope with fixed magnification 1a. In the "objective-side" part of the riflescope 1a, which faces the object 2 to be observed, an optical assembly "riflescope objective" 101 is arranged. This optical assembly can consist of a single lens, but preferably two or more than two optical lenses and / or other optically active elements are included. On the opposite side of the riflescope 1a, facing away from the object, another optical assembly "riflescope eyepiece" 102 is arranged. This optical assembly can consist of a single lens, but preferably two or more than two optical lenses or other optically active elements are included.

[0069] The optical assemblies riflescope objective lens 101 and riflescope eyepiece 102 are arranged in series such that their optical axes are at least approximately parallel; ideally, the optical axes coincide. The assemblies are held by a structure, referred to here as the "outer tube" 10. This outer tube 10 can have the shape of a rotationally symmetrical tube, but this is not required. In other words, a rotationally symmetrical tube is one with a circular cross-section. The outer tube 10 can be constructed in one piece or in multiple pieces. In particular, the optical assembly riflescope eyepiece 102 is often housed in a separate tube section 10b, which can be attached to another section of the outer tube 10 in an axially aligned manner. This separate tube section 10b can be designed to be displaceable along the optical axis for diopter adjustment.Often, the separate pipe section 10b is arranged at least partially within the outer pipe 10.

[0070] An inversion system 104 is often mounted between the riflescope objective lens 101 and the riflescope eyepiece 102. It consists of at least one optical lens, but preferably more than one optical lens or other optically effective components. The inversion system 104 is often mounted within an inner tube 11, which can be tilted and / or displaced relative to the outer tube 10 using the reticle adjustment 12. The spring 108 counteracts this movement by restoring the reticle 14. The reticle 14 is often also mounted within the inner tube. Furthermore, the inner tube can contain further optical elements, for example, one or more field lenses 103 and / or one or more Barlow lenses 109.

[0071] The light coming from an ("infinitely") distant object 2 forms an approximately parallel beam path. The riflescope objective 101 images this light into a first image plane 201 of the riflescope objective 101. The inversion system 104 images the image from the first image plane 201 of the riflescope objective 101 into a second image plane 202 of the riflescope eyepiece 102. Frequently and preferably, the reticle 14 is arranged in this image plane, but it can also be arranged in another optically conjugate plane. The observer 3 observes through the riflescope eyepiece 102 an image in the second image plane 202, which is imaged by the riflescope eyepiece 102 into a distant plane, "infinity." In other words, the riflescope eyepiece 102 produces a largely parallel beam path that can be observed by the observer 3 with a relaxed eye.

[0072] Fig. 3a and Fig. 3b shows another example of a cross-sectional view of a riflescope 1b with variable magnification. The basic design corresponds to the riflescope 1a from Fig. 2, however, here the lens group of the reversing system 104 is designed to be movable in the inner tube 11, and an additional movable lens group of the reversing system 105 is provided. Together, they form both a reversing system and a zoom system 106. Fig. 3a shows a first position of the combined reversing and zoom system 106, Fig. Figure 3b shows a second position. The individual lenses of the zoom system 106 can travel different distances during zooming and can also be moved in opposite directions.

[0073] Fig. 4 shows an exemplary sectional view through a sighting device 5 consisting of a telescopic sight 1a and an attached attachment 4. The attachment contains an attachment lens 111, which is suitable for projecting light from a distant object 2 onto an attachment sensor 113. The light projected by the attachment lens 111 and detected by the attachment sensor 113 can be visible light, but it can also be light invisible to the human eye. Such devices are often equipped to project light in the infrared spectral range. For this purpose, optical components, such as lenses, may be used which exhibit high transparency in the required spectral range. For infrared light, for example, optical components made of germanium are often used. It goes without saying that the attachment sensor must also be matched to the spectral range of interest.An image captured on the attachment sensor 113 is converted into a data set, which can be processed and modified in a data processing unit 115. For example, a contrast increase and / or a change in the image colors can be computationally performed here. The thus modified data set is displayed on an attachment display 114 by emitting light in the visible spectral range. The attachment display 114 can be observed via an attachment eyepiece 112. The attachment eyepiece 112 is equipped to exhibit high transparency in the visible spectral range of light. The attachment eyepiece projects an optical plane from the attachment display onto a very distant virtual plane, toward "infinity," thereby optically creating a so-called parallel beam path.Since a telescopic sight 1a coupled to the attachment 4 is in turn capable of allowing the observation of a distant or "infinite" object 2, which is carried out via light in a likewise parallel beam path between object 2 and telescopic sight 1a, the telescopic sight 1a is also capable of allowing the observation of the parallel beam path generated by the attachment 4.

[0074] The attachment 4 can contain one or more operating elements 116, 117. An operating element 116, 117 can be one of the following: a push-button, a control knob, a switch, a touch-sensitive element, a rotary dial, a rotary dial with integrated button function, a joystick, a microphone, a light-sensitive sensor, a light-sensitive sensor with coupled lighting. According to the invention, an operating element can also be a different element than one of those listed. The only important thing is that the element enables a user to interact with the data processing unit 115. According to the invention, the attachment can contain several similar operating elements, but also different types of operating elements.An interaction of a user, for example by pressing a button or turning a rotary wheel or the like, generates a signal to the data processing unit 115, which can be used to control the attachment 4, in particular also to carry out the method according to the invention.

[0075] Fig. 5a and Fig. 5b show another exemplary sectional image through a telescopic sight 1b and a coupled attachment 4, wherein in this example the telescopic sight 1b is equipped with a zoom system 106. The attachment 4 corresponds in its properties to those of the Fig. 4 explained. Fig. 5a shows a first zoom position of the zoom system 106 of the riflescope 1b, Fig. Figure 5b shows a second zoom position of the zoom system 106 of the riflescope 1b. The different zoom positions can be identified by the different positions of the optical components of the zoom system 106.

[0076] In the first zoom position from Fig. 5a, a first outermost light beam 221 can be observed by the observer 3. This light beam is generated on the attachment display 114 at a first pixel position 225 as a first emitted light beam 223. The light of the first emitted light beam 223 is identical to the first outermost light beam 221 on the eyepiece side. In the second zoom position from Fig. 5b, a second outermost light beam 222 can be observed by the observer 3. This light beam is generated on the attachment display 114 at a second pixel position 226 as a second emitted light beam 224. The light of the second emitted light beam 224 runs on the eyepiece side identically to the second outermost light beam 222. It is clearly visible that the light of the outermost light beams 221, 222 takes the same course on the eyepiece side and thus on the observer side, in other words, comes from the same field angle, whereas in the examples, however, these are light beams with different origins on the attachment display 114, namely from the pixel positions 225, 226. The first pixel position 225 is closer to a center 227 of the attachment display 114 than the second pixel position 226, since the Fig. 5a shows a zoom position of the zoom system 106 higher magnification than Fig. 5b. The center 227 of the attachment display 114 is considered to be the location on the attachment display 114 which lies in the center of the area observable through the attachment eyepiece 112 and the riflescope 1b.

[0077] An observer 3 is only able to see all pixels of the attachment display 114 in Fig. 5b, whose distance to the center 227 of the front-end display 114 is smaller than the distance of the pixel position 226 thereto.

[0078] Analogously, the pixels of the attachment display 114 are in Fig. 5a, which lie radially outside the pixel position 225, are in principle not observable by the observer 3 due to the high magnification of the zoom system 106 there. In other words, at a high magnification of the riflescope 1b, only a smaller section of the attachment display 114 is observable than at a low magnification.

[0079] This is illustrated by the representations in Fig. 6. The Fig. Figure 6 schematically shows, for two zoom settings of the riflescope 1b, which section of the display area of ​​the attachment display 114 can be observed through the riflescope 1b in the respective zoom position. Fig. 6 I shows the situation for a low magnification of the riflescope 1b: a subjective field of view 121 of the riflescope 1b covers a relatively large area of ​​a display surface 123 of the attachment display 114, so that the indicators 310 are observable through the riflescope 1b at a first position near the edge of the display surface. Fig. Figure 6 II shows the situation for a higher magnification of the riflescope 1b: the subjective field of view 121 of the riflescope 1b covers a relatively smaller area of ​​the display surface 123 of the attachment display 114, so that the indicators 310 at the first position 311 near the edge of the display surface are not observable through the riflescope 1b. If the indicators are displayed at a second, more inward position 312, they can be located within the subjective field of view 121 of the riflescope 1b and can be observable again.

[0080] The method according to the invention is started by operating an operating element 116, 117 of the attachment. The telescopic sight 1b should be in the zoom position to which the display structures of the attachment are to be set. The data processing unit 115 of the attachment 4 switches to the first step of the method according to the invention and displays a center marker 301a, 301b, 301c, 301d, 301e, 301f on the attachment display 114. The center marker 301a, 301b, 301c, 301d, 301e, 301f can be one of the Fig. 7 shown as examples and / or one of the following: a point, a circle, a star, a cross, a crosshair or a similar marking. Fig. Figure 7a shows six possible embodiments of the center marker 301a, 301b, 301c, 301d, 301e, 301f by way of example. The center marker 301a, 301b, 301c, 301d, 301e, 301f is suitable for identifying a center position 301 for a user. In other words, any screen display suitable for marking such a center position, called 301, on a screen in such a way that the position and / or its immediate surroundings are identified by a viewer of the screen is possible as such a center marker 301a, 301b, 301c, 301d, 301e, 301f.

[0081] The data processing unit 115 of the attachment 4 switches to a first interaction mode. The data processing unit 115 waits for the control elements 116, 117 to be activated and, upon activation, executes a corresponding action. Such an action can be: - Moving the center position 301 of the center marker 301a, 301b, 301c, 301d, 301e, 301f in a first direction and displaying the center marker 301a, 301b, 301c, 301d, 301e, 301f at a new center position 303 - Moving the center position 301 of the center marker 301a, 301b, 301c, 301d, 301e, 301f in a direction opposite to the first direction and displaying the center marker 301a, 301b, 301c, 301d, 301e, 301f at a new center position 303 - Shifting the center position 301 of the center marking 301a, 301b, 301c, 301d, 301e, 301f in a second direction and displaying the center marking 301a, 301b, 301c, 301d, 301e, 301f at a new center position 303 - Shifting the center position 301 of the center mark 301a, 301b, 301c, 301d, 301e, 301f in a direction opposite to the second direction and displaying the center mark 301a, 301b, 301c, 301d, 301e, 301f at the new center position 303 - End the first interaction mode

[0082] It is understood that for the next interaction step, the new center position 303 is to be considered the center position 301 for a next step, thus enabling a multi-stage shift of the center position 301, regardless of the direction. In other words, the center position 301 can be shifted step by step by repeatedly applying one or more of the above steps, with the new center position 303 simultaneously forming the starting position of the center position 301 for a next step.

[0083] The shift of the center position 301 to the new center position 303 is shown schematically in Fig. 7b.

[0084] According to the invention, the first interaction mode can also be terminated by the data processing unit 115 terminating it automatically after a predetermined time has elapsed without actuation of a control element 116, 117.

[0085] A further action of the data processing unit 115 can be to switch between the first displacement direction and the second displacement direction, preferably also to switch back and forth, so that the displacement in the first direction and in the second direction can be carried out by actuating the same operating element 116, 117, depending on the currently set displacement direction.

[0086] After the first interaction mode has been completed by the data processing unit 115, the value of the center position 301, 303 of the center marking 301a, 301b, 301c, 301d, 301e, 301f is stored in a non-volatile memory 122. This non-volatile memory 122 may be part of the data processing unit 115 or it may be electronically connected to the data processing unit 115.

[0087] After completing the first step of the method according to the invention, the data processing unit 115 of the attachment 4 switches to the second step of the method according to the invention and displays a circular marker 302a, 302b, 302c, 302d on the attachment display 114. According to the invention, the circular marker 302a, 302b, 302c, 302d is displayed such that it is centered around the last center position 301, 303 of the center marker 301a, 301b, 301c, 301d, 301e, 301f. According to the invention, the display of the center marker 301a, 301b, 301c, 301d, 301e, 301f can be switched on or off in this step. The circular marking 302a, 302b, 302c, 302d may be one of the Fig. 8 shown by way of example and / or by way of example one of the following selection: a solid circle, a segment of a circle, a regularly or irregularly dashed circle, a regularly or irregularly dotted circle consisting of at least three points. Fig. Figure 8 shows examples of this: a circle marking as a dashed circle (top left), a circle marking consisting of two circular segments (bottom left), a circle marking consisting of geometric figures and numbers arranged on a circular line (top right), and a circle marking consisting of a dotted-dashed line (bottom right). The data processing unit 115 of the attachment 4 switches to a second interaction mode. The data processing unit 115 waits for the operating elements 116, 117 to be activated and, upon activation, executes a corresponding action. Such an action can be: - Enlargement of the radius of the circle marker 302a, 302b, 302c, 302d in two dimensions and display of the circle marker 302a, 302b, 302c, 302d in the new size - Reducing the radius of the circle marker 302a, 302b, 302c, 302d in two dimensions and displaying the circle marker 302a, 302b, 302c, 302d in the new size - Enlarging the radius of the circle marking 302a, 302b, 302c, 302d in a first dimension and displaying the circle marking 302a, 302b, 302c, 302d in the new size - Reducing the radius of the circle marking 302a, 302b, 302c, 302d in a first dimension and displaying the circle marking 302a, 302b, 302c, 302d in the new size - Enlargement of the radius of the circle marking 302a, 302b, 302c, 302d in a second dimension and display of the circle marking 302a, 302b, 302c, 302d in the new size - Reducing the radius of the circle marker 302a, 302b, 302c, 302d in a second dimension and displaying the circle marker 302a, 302b, 302c, 302d in the new size - Changing the radius of the circular marking 302a, 302b, 302c, 302d to a new size of a discrete list of fixed sizes stored in the data processing unit 115 and displaying the circular marking 302a, 302b, 302c, 302d in the new size - End the second interaction mode

[0088] According to the invention, the second interaction mode can also be terminated by the data processing unit 115 automatically terminating it after a predetermined time has elapsed without actuation of a control element 116, 117.

[0089] A further action of the data processing unit 115 may be to switch between the first dimension of the change and the second dimension of the change, preferably also to switch back and forth, so that the change of the size in the first dimension and in the second dimension can be carried out by actuating the same control element 116, 117, depending on the currently set direction.

[0090] After the second interaction mode has been completed by the data processing unit 115, the value or values ​​of the size of the circular marking 302a, 302b, 302c, 302d are stored in the non-volatile memory 122. The non-volatile memory 122 may be part of the data processing unit 115 or it may be electronically connected to the data processing unit 115.

[0091] Preferably, the attachment 4 directly after completion of the second step according to the invention adjusts the display of information on the attachment display 114 such that such displayed information is only displayed within an area of ​​the attachment display 114 that lies within the radius of the size of the circular marking 302a, 302b, 302c, 302d selected in the second step.

[0092] Optionally, after completion of the second step, a third step according to the invention can follow, in which the data processing unit 115 switches to a third interaction mode. In this interaction mode, the data processing unit 115 waits for the actuation of the operating elements 116, 117 to define a profile storage location in the non-volatile memory 122. A menu and / or similar information that may be required to select the profile storage location are preferably displayed in an area of ​​the attachment display 114 that lies within the radius of the circular marking 302a, 302b, 302c, 302d selected in the second step. This ensures that the required information and / or menus can be observed with the current magnification setting of the riflescope 1b.

[0093] The third step, like the first two steps, is also terminated according to the invention either by actuating a control element 116, 117 and / or automatically after a predetermined period of time without user interaction. In particular, according to the invention, selecting a profile storage location from a variety of profile storage locations offered to the user by actuating a control element 116, 117 can lead to the termination of the third step and thus the third interaction mode after the profile data, in particular the data on the center position 301, 303 of the center marking 301a, 301b, 301c, 301d, 301e, 301f and the size of the circular marking 302a, 302b, 302c, 302d, have been stored in the selected profile storage location of the non-volatile memory 122.

[0094] When using the sighting device 5, for example during hunting, it can be provided that a user selects a profile memory location by actuating one or more operating elements 116, 117, whereupon the attachment 4 switches to a display mode such that the further display of information and / or menus and / or icons and / or symbols are only displayed within the radius stored in the selected profile memory location around the center point stored in the selected profile memory location.

[0095] Fig. 5c shows as a further embodiment the Fig. 5a and Fig. 5b shown sighting device 5 in the zoom position of the Fig.5b, wherein this sighting device 5, in addition to the features of the previous embodiments, is equipped with a zoom sensor 118 for detecting the zoom position or magnification of the riflescope with variable magnification 1b. The zoom sensor can contain a controller that converts the physical measured value into digital or similar zoom information. This zoom information can, for example, be information about the magnification of the riflescope 1b, but also, for example, information about the image scale of the optical group provided for the zoom. Furthermore, the sighting device 5 has means for wireless communication for exchanging data between the riflescope 1b and the attachment 4. The means for wireless communication consist of at least one first radio unit 119 on or in the riflescope 1b and at least one second radio unit 120 on or in the attachment 4.The first radio unit 119 and the second radio unit 120 can each be designed as a transmitter and / or a receiver. Particularly preferably, both the first radio unit 119 and the second radio unit 120 have the ability to both transmit and receive, so that bidirectional communication is possible. However, it is also conceivable for only one of the units 119, 120 to be a transmitter and the other a receiver, so that unidirectional communication is possible. To ensure full functionality, a second pair of radio units 119, 120 is used in this case, which has swapped roles with the first pair and allows unidirectional communication in the other direction. The first radio unit 119 and the second radio unit 120 can exchange digital signals, for example via Bluetooth or WLAN or using another comparable technology for wireless data transmission.The zoom sensor 118 detects the magnification set by the user 3 on the rifle scope and converts this into digital zoom information. This digital zoom information can be transmitted wirelessly from the first radio unit 119 to the second radio unit 120. Such transmission can take place both during implementation of the method according to the invention and during (hunting) use of the sighting device. To query the zoom position, the attachment 4 can send a trigger signal to the rifle scope 1b via the wireless communication means, second radio unit 120 and first radio unit 119. Triggered by this trigger signal, the zoom sensor 118 determines the magnification or zoom position set on the rifle scope 1b. The zoom information thus determined about the set.

[0096] Magnification is then transmitted to the attachment 4 via the wireless communication means, the first radio unit 119 and the second radio unit 120. The zoom information about the set magnification or zoom position can be stored in a profile memory location of the attachment 4 in order to be used for optimal adjustment of the display in the manner described during subsequent use of the riflescope 1b.
