The present disclosure relates generally to systems and methods to capture, display, and share images captured by an optical device. More particularly, the present disclosure relates to capturing and sharing images captured by a scope for a rifle.
Optical devices such as telescopes, binoculars, and hunting scopes have long been used to magnify images seen at a distance. The magnification of objects at a distance allows the user of the optical device to make more informed decisions about what they are looking at. For example, Galileo used a telescope to help establish that the sun was indeed the center of the solar system.
Hunting scopes attached to rifles and other weapons also provide advantages to hunters and marksmen. A hunting scope may be coupled to rifle to improve the accuracy of the marksman and may effectively increase the usable range of the rifle. Because distant objects appear to be closer when looking through a hunting scope, a marksman may find it easier to precisely target an object with the hunting scope.
One typical drawback of optical devices is that only one user may view an object through the optical device at a time. There is a need to be able to share images captured by an optical device with others, without distorting the image observed by the user of the optical device. Another drawback of optical devices is that the user of the optical device cannot analyze any additional information while looking through optical device. The optical device tends to fill the user's entire field of view. There is a need to be able to display supplemental information to a user of the optical device through the optical device.

A further understanding of the nature and advantages of the embodiments may be realized by reference to the following drawings. In the appended figures, similar components or features may have the same reference label.
While the embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the exemplary embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
The present disclosure is generally directed toward technologies for capturing images seen through an optical device, such as a scope, without distorting or obscuring the view of the user of the optical. The technologies may also share the images with a computing device in real-time such that another person using the computing device may view what the user sees in real-time. The technologies may also obtain and display information via the optical device to the user. The technologies described herein describe apparatus and methods that may be used to integrate an optical device with the other devices.
In the proposed design, a digital input/output (“I/O”) system may include a camera, a beam splitter, optics (e.g., lenses, mirrors, etc.), and a housing that encloses circuitry used to capture and communicate the image seen through the scope. The digital I/O system may also include electronic circuitry for processing the image and for communicating the image to other devices, such as a mobile computing device. A beam splitter may redirect a first portion of a beam traveling through an optical device toward the camera. The beam splitter may also allow a second portion of the beam to pass through the beam splitter and continue on to the user's eye. In this way, both the user and the camera may be configured to observe the image being presented by the optical device.
In the hunting context, a hunting scope may be equipped with the image capture/display device. A marksman may desire to share the image being seen through the hunting scope with another person. For example, during marksman training, a student or teacher may desire to view what the other sees through the hunting scope.
In this way, the teacher may be able to offer more specific advice to the help the student improve or the student may be able to observe first-hand the proper way to use the hunting scope. The marksman may desire to evaluate other information without interrupting the use of the hunting scope. For example, the marksman may desire to know the wind speed or the range to the objective without taking his or her eyes away from the hunting scope. In some instances, the situation is not well suited for audible communication.

In some instances, another computing device may combine the support data and the indicators with the image captured by the imaging device 315 to generate a composite image. The composite image being a replica of the image presented at the exit pupil 935.
As discussed above, the data display components 210 may be utilized with the image capture components 205. In some examples, the side of the beam splitter 805 facing the user may be utilized to project information from one or more display elements to the user, such that the information is laid over part or all of the incoming image in such a manner that it allows the user to see the incoming image from the optical device 110, but presents either visible data (e.g., digital information, such as, compass heading, range, wind speed, time, etc.) or a see-through regional overlay such that the digital image component accents the image from the optical device 110 with highlights (i.e. low light level image, thermal image, image processed components (e.g., marking of objects in motion, colorimetry data, object shape analysis, etc.). The user may have the ability to choose which display options are being used and where they are presented on the field of view.
The beam splitter(s) 805 may be positioned in a primary optical path 910 of the optical device 110 between the objective optics 125 and the ocular optics 135. The housing 120 of the optical device 110 may be modified to allow the various beams to enter and exit the housing 120. For example, an opening 915 may be formed in the housing 120 to allow a display beam 835 from the data display components 210 to enter the housing 120 and an opening 925 may be formed in the housing 120 to allow an imager beam 845 to exit the housing 120. Because the beam splitter(s) 805 are positioned between the objective optics 125 and the ocular optics 135, the image of the objective 330 split by the beam splitter(s) 805 may not be in focus. In such embodiments, the optics of the image capture components 205 and the data display components 210 may modify the images such that user of the optical device 110 observes indicators that are in focus after passing through the ocular optics 135 and the user of the computing device observes a useful image. In some examples, housings are positioned in and around the image capture components 205 and the data display components 210.
The optical device 110 may also define an exit pupil 935 and an eye relief 940. The exit pupil 935 is the image-forming light the optical device 110 presents to a user's eye 340. To use an optical device, an entrance pupil of the user's eye 340 should be aligned with and be of similar size to the exit pupil 935. This properly couples the optical system o the eye 340 and avoids vignetting. The position of the exit pupil 935 relative to the last surface of the optical device 110 determines the eye relief 940 of the optical device 110. The eye relief 940 is the distance between the last surface of the optical device 110 at which the user may observe a full viewing angle. An exit pupil 935 may have a diameter approximating the eye's apparent pupil diameter. If the exit pupil diameter is larger than the eye's pupil, light will be lost instead of entering the eye; if smaller, the view will be vignetted. If the exit pupil 935 is positioned too close to the last surface of the eyepiece, the eye may be uncomfortably close for viewing; if too far away, the user may have difficulty maintaining the eye's alignment with the exit pupil 935.
The I/O device 905 may be positioned to within the optical device 110 and prior to the eyepiece such that it diverts an image prior to passing through the eyepiece. In this manner, the user may utilize the optical device 110 without adjusting the eye relief 940 relative to the ocular optics 135. In this embodiment, optics for the imaging device may be modified to compensate for the optical elements that the image misses in the optical device 110 and thereby provides the imaging device with a comparatively similar viewing scene to the original optical device as viewed by the user.
The beam splitter(s) 805 may be positioned between in a primary optical path 1010 defined by the optical device 110 between the ocular optics 135 and the exit pupil 935. In some examples, the I/O device 1005 is contained within an I/O housing 160, In some examples, the I/O device 1005 may include additional optics that alter the position of the exit pupil 935. For example, if an attachment is added to the second end 140 of the optical device 110, the eye relief 940 may become uncomfortably small for the user. In such examples, the I/O device 1005 may include optics to move the eye relief such that it is a comfortable distance from the last optics of the I/O device 1005.
The I/O device 1005 may be positioned at the second end of the optical device 110. The I/O device 1105 may utilize the beam splitter(s) 805 placed between the eyepiece lens (e.g., ocular optics 135) and where the user would place their eye 340 to view the scene through the optical system (e.g., exit pupil 935). The beam splitter 805 may deflect part of the image light away from the observer position and direct it to an imaging device (either directly or via a folding mirror). The imaging device may be designed to accommodate the incoming image (or work with a correction lens) and bring it into focus on a digital imaging sensor. This allows a user of the optical device 110 to continue using the system in a normal manner, except for a slight increase in the distance from the eyepiece lens to their eye which provides the space needed for the beam splitter 805. It may also allow the image that the user sees through the optical device 110 to be imaged by the imaging device sensor and recorded in a digital memory, and/or transmitted to other devices. The use of a folding mirror in the design may allow for the imaging device and electronics package to be placed along the side of the housing 120 or near to an optical axis.
The network 1125 may be a wired or wireless network, or any combination thereof, For example, the network 1125 may be embodied as Ethernet, Wi-Fi, cellular, LTE, Bluetooth, local area network, public network, optical network, the Internet, and/or any other type of network. The network 1125 may include more than one type of connection (e.g., wired and wireless connections) in a single implementation. In some examples, the network 1125 is an ad hoc network.
The network 1125 may be connected to one or more other networks 1135, such as the internet. From these other networks 1135, the I/O device 115 may send or receive data (e.g., the I/O device 115 may receive support data from these other networks). In some examples, the computing device 1110 acts as a gateway device for the I/O device 115. Meaning, the I/O device 115 may not connect to the other networks 1135 directly, but sends and receives data to and from these other networks 1135 through another device such as the computing device 1110.
The system 1100 may enable the I/O device 115 to be used in a number of applications. For example, by allowing the I/O device 115 to communicate through the network 1125 with other devices, images from a spotting scope, thermal imaging system, etc. may be shared, on-demand, with the I/O device 115, such that the user can switch between the image from the spotting scope 1115 and the optical device 110 coupled to the firearm 410. In a similar manner, support data from an electronic compass, GPS, range finder and/or other peripheral device may be shared via the network 1125. The data may be presented to the user through the I/O device 115 incorporated into the optical device 110. Network communication between the I/O device 115 and the peripheral products (e.g., mobile phones or other optical scopes), may be done in an encrypted format for security to prevent intrusion or interference from outside systems that could falsify or destroy the information.
In other examples, the I/O device 115 may incorporate image processing capabilities to utilize range, wind speed and other support data from various sensors and peripheral device to calculate an adjustment position from the crosshair point to the position of where a bullet will strike the target. The adjustment position may be presented to the user as the shot correction indicator 760 shown in
In other examples, the I/O device 115 and the system 1100 may be configured to perform other applications. The system 1100 may be configured to capture and record still images or video of animals, targets, scenes, etc. while hunting, or nature watching through a rifle scope, spotting scope, telescope, binoculars, or other optical devices 110. The system 1100 may be configured to share in real-time what the user of an optical device is seeing through the optical device 110. The system 1100 may be configured to allow a student or a teacher to view what the other sees and how they are aligning sights or centering an object of interest in the scene for image capture, shooting, etc. The system 1100 may be configured to observe animals and record identifying marks along with location and additional information via peripherals devices or the internal electronics of the I/O device 115. The system 1100 may be configured to display information pertinent to shooting a target or animal as accurately as possible. Such information can include wind speed and direction, range, altitude, etc. The information may be selectable based on the users requirements and the peripheral devices and sensors that are linked to the I/O device 115.
The system 1100 may be configured to integrate data from networked tools such as a range finder, wind speed and direction, and altitude are combine them with data on the type of weapon and shell being fired to provide corrected targeting information to accurately place a shot on target. Calculations may include the explosive type and number of grains and grain size being used in the shells being fired to provide accurate ballistic information. Some of this data may be input by a user into the system 1100. The system 1100 may be configured to display an electronic crosshairs where the position of the displayed crosshairs has been moved to match the data from calculations based on information from networked sensors, stored data and from the scope image. The system 1100 may be configured to use of data from sensors such as GPS and eCompass to identify the direction of fire that the user is planning, and comparing that with information from a maps application to indicate and warn the user of potential safety risk from firing in that position. This can include updated information of the presence and location of other hunters and observers.
The system 1100 may be configured to aid in competitions. For example, the system 1100 may record the location of a shot, video and/or still image of the shot to hit a target or animal. The eCompass and range data showing the location on a map of both the user and the target may also be recorded. This data may be used in target and/or hunting competitions. The information can then be compiled for each participant in the competition to indicate who made the most accurate shot, the longest shot, the most difficult shot, the size and class of the animal, and many more items of information. This opens a wide variety of competitive applications. These competitions can be applied to a variety of nature watching as well as hunting. In some embodiments, the system 1100 may determine a targeting skill parameter for a user based at least in part on a position of the objective in the image obtained by the optical device or based at least in part on a location of a projectile as it moves past the objective, compare the targeting skill parameter of the user to one or more other targeting skill parameters of other users of other optical devices, and indicate which of the users had a best targeting skill parameter.

Referring now to the other computing devices 405, 1110 of
The optical device housing 1320 may be sized to receive the housing 120 of the optical device 110. The optical device housing 1320 may also be configured to secure the I/O device 1300 in a fixed position relative to the optical device 110 using some type of fixation means. For example, the optical device housing 1320 may couple to the optical device 110 via a friction fit, a fastener such as a screw, strap, or adhesive, or some other type of fastener. In some examples, the I/O housing 1305 may include only the electronics housing 1315 because the beam splitter and the other optics may be integrated into the optical device 110 such that the beam splitter and the other optics are positioned in the housing 120 (e.g., I/O device 905).
In use, the beam 1425 of light may be received into the I/O housing 1405 through an opening 1455 formed in the I/O housing 1405. Once inside the cavity of the I/O housing 1405, the beam 1425 may be redirected according to the position and configuration of the imaging device 1415 and the auxiliary optics 1410. For example, the beam 1425 may be redirected by a folding mirror 1460. The auxiliary optics 1410 are configured to adjust the beam 1425 on the optics 1435 of the imaging device 1415. In some examples, this is done by altering the position and/or the diameter of the auxiliary exit pupil 1430. The beam 1425 is then received into the imaging device 1415. The imaging device generates an image based at least in part on the beam 1425. The image is then communicated by communication circuitry 1445 or other electronics 1420 to another computing device 405 via a network. In some examples, the components positioned in the I/O housing 1405 (e.g., 1410, 1415, 1420) may be similarly embodied as the image capture components 205.
In some examples, a link 1465 may be established between the communication circuitry 1445 and the other electronics 1420.

The imaging device may include optics 1550, imaging circuitry 1555 or communication circuitry 1560. These components 1550, 1555, 1560 may be similarly embodied as the components described in relationship to the image capture components 205. The optics 1550 may be any type of lens or other optic used by the imaging device 1515. The imager housing 1530 may be configured to adjust a position and orientation of the imaging device 1515 relative to the auxiliary optics 1510. In addition, the auxiliary optics 1510 may be configured to adjust a position, orientation, and size of the auxiliary exit pupil 1545 to better align with the optics 1550 of the imaging device 1515.
In some examples, a link 1565 may be established between the communication circuitry 1560 and the other electronics 1520.

In such an example, the imaging device 1515 may connect to the other electronics 1520 via a wired link or a wireless link (e.g., link 1565), and the other electronics 1520 may connect to the network.
