Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to the field of loupes. More particularly, the invention relates to a method and apparatus for capturing the visual field of a jeweler&#39;s loupe and transmitting this capture to a remote user. 
       BACKGROUND ART 
       [0002]    A loupe or a magnifying lens is a device frequently associated with jewelers, usually taking the form of a simple positive lens. In use, the magnifier is held close to the eye, while the object to be viewed is brought to the focal point of the lens. In typical use to view gems the loupe is held almost against one eye and the gem is held with tweezers and inspected through the loupe. The viewer typically inspects the surface of the gem but far more emphasis is placed on looking inside the gem for imperfections that could affect the clarity grading. 
         [0003]    During a typical gem purchase, a buyer will inspect the gems at the seller&#39;s premises since it is very costly to ship the gems to the buyer. Further, the seller may not agree to ship the gems at all necessitating local inspection. The buyer may therefore need to send an agent to visit the seller and inspect the gems giving rise to a situation where the remote buyer does not see the gems and must rely on the inspection of the local agent. The agent may inspect hundreds or thousands of gems and the buyer might pay for the gems based on the agent&#39;s examination only to find that there are imperfections that the agent missed. 
         [0004]    A mechanism is therefore required that allows a remote buyer to view the gems as the local agent is inspecting them. Similarly, this mechanism is also required in other fields such as the inspection and purchase of fine art or antiques. 
         [0005]    US 20050024530 to Schuttinger teaches a magnifier for visually impaired individuals with a camera mounted on the side of the magnifier. The device of Schuttinger places the camera on the side of the magnifier and the camera does not capture the image seen through the magnifier. Further, the device does not conform to the form factor of a typical jeweler&#39;s loupe. 
         [0006]    One existing solution requires the addition of a clip-on magnification lens to a smartphone. The clip-on lens fits over the built-in camera of the smartphone and this camera is then used to capture a magnified image or movie of the analyzed gem. The captured image is viewed locally and may be transmitted to a remote party using standard image sharing applications. This solution is not favored by industry professionals who prefer the loupe as a more natural inspection tool and find the phone unwieldy due to its relative weight and the difficulty of positioning the device over the gem to be viewed. Further the local viewer does not view the gem directly but rather sees it on the screen of the device. Finally, the standard image sharing applications do not provide any mechanism to make specific comments about the viewed object, or calculate parameters related to the object, particularly in the field of gems. 
         [0007]    A further solution requires the local viewer to wear a head-mounted camera or camera mounted within a pair of glasses to capture the view of the gem as seen locally and then transmit this to a remote party. This approach is also not favored since the head-mounted camera does not capture the same image as seen through the loupe of the local viewer, which is held in front of the eye and not in front of the camera, and it is very difficult to line up the gem, loupe and camera to provide this view. 
       SUMMARY OF THE INVENTION

       DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0040]    The present invention is of a system and method for transmitting the magnified view seen by local viewer using a handheld loupe to a remote viewer. To capture the view seen by the local user, the loupe is equipped with a camera preferably mounted on, or proximal to, the standard loupe lens. The loupe preferably includes means for transmitting the image captured by the camera to a nearby computing device such as a smartphone or laptop computer. These computing devices in turn preferably transmit the images to a remote viewer so that this viewer can essentially see what the local user sees. 
         [0041]    The loupe is preferably equipped with a button or other means allowing the local user to initiate image capture. The user may also optionally capture video and the term captured view or capture as used herein may refer to either image or video. The captured view is optionally stored locally on the loop and can then be copied from the loupe. 
         [0042]    Optionally the camera is mounted on the proximal side of the loupe lens closer to the user such that the camera captures the view seen through the lens. Optionally the camera is mounted on the distal side closer to the object to be viewed where the camera includes optics that allow approximation of the view on proximal side of the loupe lens. Optionally, the loupe includes a beam splitter or similar optical component so that the camera and viewer are presented with identical views. Optionally, the loupe includes more than one camera to capture different views of the viewed object. Optionally the loupe is equipped with means for illumination on the distal side to illuminate the viewed object. 
         [0043]    Preferably, the capture is transferred to a computing device wirelessly. Optionally the capture is transferred manually using some form of portable media that is inserted or otherwise attached to the loupe. Optionally a cable may be used to connect the loop with a computing device to allow transfer of the captures from the loop to the computing device. 
         [0044]    Preferably, the computing device is running dedicated software herein referred to as an application or app. The app preferably includes capabilities such as; establishing a wireless connection to the loupe, receiving and displaying captures transmitted by the loupe, annotating captures, storing captures, and sharing captures. Preferably the remote user uses the same app running on a computing device to view the shared captures. 
         [0045]    Optionally the captures are shared using non-dedicated software running on the computing device. Non-limiting examples of non-dedicated software include email or other messaging applications or services such as instant messaging. 
         [0046]    In an exemplary and non-limiting usage scenario a user would activate the app on a smartphone and initiate a wireless connection to the loupe. The user would then initiate a connection to a remote user who is also running the app on a smartphone. The user then holds the gem or object to be analyzed in one hand and holds the loupe in the other hand and positions the loupe close to the eye. The object may also, for example, be of dimensions, or of value such that it is not possible to hold the object. Thus the loupe may for example be used to inspect works of art, or damage to an article or any other type of viewing requiring magnification. 
         [0047]    The gem or object is then held at the focal length of the loupe, or the loupe and viewer move to a focal length opposite the object, and the gem or object is examined. When the user sees a point of interest the capture is initiated. This capture is transmitted to the app on the local smartphone and transferred to the app on the smartphone of the remote user where the capture of the view seen by the local user is displayed on the screen of the device. 
         [0048]    Optionally the various embodiments and subembodiments of the below figures may also optionally be combined. Some non-limiting examples of such combinations are provided below, but these are only examples and any other combination may also be considered to fall within the scope of the present invention. 
         [0049]    Reference is now made to  FIG. 1  which is a simplified pictorial illustration of light rays passing through a prior art magnifying lens such as that found in a loupe. A prior art lens  70  is a convex lens. The typical distance of the viewed object  24  from lens  70  is the focal length  34  of lens  70 . Thus, lens  70  directs all the rays  46 A emanating from point  36 A of object  24  to be parallel one to the other, being rays  48 A; and lens  70  directs all the rays  46 B emanating from point  36 B of object  24  to be parallel one to the other, being rays  48 B. 
         [0050]    Parallel rays  48 A and  48 B emanating towards eye  38  provide relaxed focusing of the eye to the retina  44 . Thus, eye  38  imagines that rays  46 A emanating from point  36 A coming from an angle  40 A, emanate from an infinite object  42 A having an angle  44 A. 
         [0051]    The term “infinity rays” refers herein to parallel rays  48 A and  48 B, since they resemble rays emanating from a very distant object. Thus, the magnification that lens  70  provides is angle  44 A divided by angle  40 A. 
         [0052]    Reference is now made to  FIG. 2  which is a simplified pictorial illustration of light rays passing through a loupe according to some embodiments of the present invention. Loupe  10  includes a camera  26 , and lens  22 . Camera  26  may be an infinity-focus camera or may be an auto-focus camera including the mechanisms necessary to allow it to focus on the object examined through the loupe. In  FIG. 2  lens  22  directs parallel rays  48 A and  48 B to the eye  38  and also to camera  26 . A first portion  58  of infinite rays  48 A and  48 B emanate towards eye  38 , and a second portion  60  of infinite rays  48 A and  48 B emanate towards camera  26 . 
         [0053]    As shown in  FIG. 2  camera  26  includes a lens  52  disposed at a fixed distance from the image sensor thereof  54 , the distance being the focal length  56  of lens  52 . Camera  26  is preferably positioned on the proximal side of lens  22  and near the edge of lens  22  so that camera  26  does not obstruct the view of eye  38 . Preferably, camera  26  must be designed and positioned such that the view seen by camera  26  and the resultant capture is as close as possible to the view of eye  38  through the center of lens  22 . 
         [0054]    Reference is now made to  FIG. 3  which is a simplified pictorial side view illustration and  FIG. 4  which is a simplified pictorial top perspective illustration of a loupe with an attached camera according to some embodiments of the present invention. As shown, a gem  24  held by tweezers  28  is visible through lens  22 , directly by the viewer and also by camera  26  which is mounted on the edge of the proximal side of lens  22 . Lens  22  preferably provides 10× magnification. Optionally lens  22  provides magnification between 2× and 10×. Optionally lens  22  provides magnification between 10× and 30×. Optionally lens  22  comprises more than one lens. Lens  22  preferably has a diameter between 12 and 22 mm. Lens  22  preferably has a focal range between ⅛ of an inch to about 1¼ of an inch. 
         [0055]    Optionally camera  26  may be fixed at an angle where it is tilted to better face the object that is being examined. Camera  26  is positioned on the edge of lens  22  so as to capture the view through lens  22  without disrupting the view of the user through lens  22 . 
         [0056]    Lens  22  is surrounded by a frame  20 , pivotally connected to a handle  12 . Optionally, handle  12  includes a button  14  for activating the capture. Optionally, a short press on button  14  captures a still image, and a long press on button  14  captures a video. Optionally, a further press on button  14  stops video capture. 
         [0057]    Reference is now made to  FIG. 5  which is a simplified pictorial perspective view of the loupe with an attached camera partially folded into an associated handle according to some embodiments of the present invention. In the depicted embodiment a data connection port  16  and memory card slot  18  are provided. Captures from camera  26  are optionally stored on internal camera memory (not shown) or optionally on a memory card (not shown) inserted into slot  18 . Non-limiting examples of memory cards that may inserted into slot  18  and used to store captures include secure digital (SD), MiniSD, MicroSD, Memory Stick DUO, Memory Stick PRO-HG Duo, Memory Stick Micro M2, and others. Data connection port  16  allows the connection of a data cable for transfer of captures to a computing device (not shown) from the memory (not shown) of camera  26  or from the memory card (not shown) inserted into slot  18 . Non-limiting examples of data ports include Universal Serial Bus (USB), IEEE 1394 (FireWire), Thunderbolt, or others. 
         [0058]    Loupe  10  is shaped like a prior art loupe and may be folded similarly. For example, a depression  30  within handle  12  encasing lens  22 , may allow sliding camera  26  therewithin, for folding lens  22  within handle  12 . 
         [0059]    Reference is now made to  FIGS. 6A ,  6 B, and  6 C which are simplified pictorial top and bottom view illustrations of a loupe according to some embodiments of the present invention. As shown in  FIG. 6A , a loupe  110  comprises a lens  122  surrounded by a frame  120  is connected to a handle  112  via pivot  140 . Lens  122  may be folded into handle  112  when not in use.

Optionally lens  122  comprises more than one lens. Lens  122  preferably has a diameter between 12 and 22 mm. Lens  122  preferably has a focal range between ⅛ of an inch to about 1¼ of an inch. 
         [0061]    Camera  126  is mounted on the edge of the proximal side of lens  122  so as not to disrupt the view of the user through lens  122  while being positioned to capture the view that is almost the same as that seen by the loupe user. Optionally camera  126  may be positioned at a fixed angle to better face the object that is being examined. 
         [0062]    Button  114  is preferably mounted on frame  120 . Button  114  is pressed by the user of the loupe to activate the capture. Optionally, a short press on button  114  captures a still picture, and a long press on button  114  captures a video. Optionally, a further press on button  114  stops video capture. 
         [0063]    Raised enclosure  150  preferably houses data storage  152 , wireless communication interface  154 , controller  156 , and battery  158 . Data storage  152  stores captures from camera  126 . 
         [0064]    Wireless interface  154  preferably enables communication between loupe  110  and a nearby computing device that is within 10 meters of loupe  110 . Any type of short range wireless interface may be used. Non-limiting examples of interfaces include WiFi, Bluetooth, or Near field communication (NFC). Optionally, a wired interface port (not shown) is provided for connecting to the nearby computing device with a suitable data cable. 
         [0065]    Controller  156  manages the storage of captures and the transfer of these via wireless communication interface to an external computing device. Controller  156  also manages establishment of communications with an external computing device via interface  154 . Controller  156  is connected to button  114  and camera  126  so as to manage their functioning. 
         [0066]    Battery  158  provides power to storage  152 , interface  154 , and controller  156 . Battery  158  is preferably rechargeable and loupe  110  is provided with connection means (not shown) to recharge battery  158 . Alternatively battery  158  is not rechargeable and raised enclosure  150  may be opened to allow replacement of battery  158 . 
         [0067]    Optionally storage  152 , communication interface  154 , controller  156  and battery  158  may be enclosed or housed in any part of loupe  110  such that raised enclosure  150  is not needed. 
         [0068]      FIG. 6B  depicts the loupe described with reference to  FIG. 6A  with the addition of a second camera  160 . Second camera  160  may be positioned to capture an alternate view to that captured by camera  126 . Additional cameras (not shown) may similarly be added to loupe  110 . 
         [0069]      FIG. 6C  depicts the loupe described with reference to  FIG. 6A  shown from the distal side. In this embodiment camera  170  and second camera  172  are mounted on the distal side of lens  122 . Cameras  170  and  172  preferably combine optical components, such as camera lens  174 , and digital zoom to provide a capture that approximates the view seen by the user on the proximal side of lens  122 . Optionally, only one camera may be provided. Optionally, more than 2 cameras may be provided. 
         [0070]    Optionally, illumination source  176  is mounted on frame  120  to illuminate the object being examined through the loupe. Preferably illumination source  176  is a light emitting diode (LED). Optionally, multiple illumination sources may be provided. Optionally, illumination source  176  may emit ultraviolet light to aid in the detection of clarity enhanced gems. 
         [0071]    Reference is now made to  FIG. 7  which is a simplified pictorial cross sectional illustration of a loupe with a camera and beam splitter according to some embodiments of the present invention. The beam splitter  180  splits the rays from the viewed object  194  so that an incident ray  188  striking the splitter  180  both passes through the splitter  180  and is reflected off the splitter  180 . As shown, camera  184  is positioned to capture the reflected rays  190  while the rays that pass through  192  are magnified by lens  122  before being viewed by the user. 
         [0072]    This arrangement allows camera  184  to capture the identical view seen by the user. Optionally camera  184  is provided with optical components such as lens  186  and digital zoom to mimic the magnification provided by lens  122 . 
         [0073]    Beam splitter  180  may be based on any beam splitter type known in the art including but not limited to a cube formed from 2 prisms, a half-silvered mirror or similar flat surface, or a dichroic prism. 
         [0074]    The introduction of a beam splitter may reduce the light intensity from the viewed object and it may therefore be necessary to include an illumination source, such as illumination source  176  depicted in  FIG. 6C , to compensate for this reduction. 
         [0075]    Reference is one made to  FIG. 8A  which is a simplified pictorial top view illustration of a loupe with a camera positioned to view a gem and  FIG. 8B  which is an exemplary view of the screen of an application for capturing an image transmitted by the loupe with a camera according to some embodiments of the present invention. 
         [0076]    As shown in  FIG. 8A , gem  210  is examined using loupe  110 . Gem  210  is held by tweezers  212 . The purpose of examination is to determine to what extent the gem is flawed. Typically, the viewer looks for surface blemishes including but not limited to polish lines, grain boundaries, naturals, scratches, nicks, pits, chips, and breaks as well as internal inclusions including but not limited to clouds, feathers, included crystals or minerals, knots, cavities, cleavage, bearding, internal graining, pinpoint, and laser lines. 
         [0077]    Gem  210  is shown as including inclusions  214  and  215  which are visible after being magnified by lens  122 . Loupe  110  is in wireless communication with nearby mobile computing device  220  via communication interface  154 . When the loupe user presses button  114 , the view of the gem through lens  122  is captured by camera  126 . The captured image is optionally stored in storage  152  and then transmitted via communication interface  154  to mobile device  220 . 
         [0078]    Mobile device  220  is preferably running a dedicated app for receiving, editing and transmitting of the capture from loupe  110 . The screen  222  of device  220  is used to display the user interface  224  of the app. User interaction with the app is via the interface mechanism which depends on the interface capabilities of the device. Non-limiting examples of interface mechanisms include a touch screen, keyboard, pointing device or others. 
         [0079]    The exemplary app user interface  224  displays the capture  230  received from loupe  110 . The capture shows the gem  210  and its inclusions  214  and  215  which were seen directly through loupe  110 . The app preferably provides the following functionality based on virtual buttons presented in app interface  224 : 
         [0080]    Add marker button  240  preferably allows the user to annotate the capture with indicators such as indicator  242  and indicator  244  that are positioned to point out inclusions  214  and  215  respectively. Optionally the user may add text annotations to the capture (not shown); 
         [0081]    Add data button  246  preferably allows the addition of standard gem data such as the color, cut or weight, which is then combined with the capture—optionally by addition of fields to the EXIF headers of the capture; 
         [0082]    Transmit button  250  preferably allows the local user to establish a connection with a remote user who is also running dedicated app on a computing device. The connection is established over a network using any network technology including but not limited to a local area network, a wide area network, the Internet, a wireless data network including: a cellular network, a WiMAX network, an EV-DO network, an RTT network, a Flash-OFDM network, an iBurst network, an HSPA network, an EDGE network, a GPRS network, a GPS satellite network, a Wi-Fi network, a UTMS network, an LTE network, and/or any combination of the aforesaid networks, which may optionally be private or public networks. 
         [0083]    Once a transmit session has been initiated with a remote user, all captures will automatically be sent to the remote user for display on the remote device. Optionally, the session includes two-way audio transmission allowing the local and remote users to discuss the captures; 
         [0084]    Share button  252  preferably allows the user to share the capture with a third party. The sharing may optionally be to a user who is running the dedicated app on a different device. Alternatively the sharing may make use of messaging applications known in the art. Use of the dedicated app provides additional functionality over known sharing applications such as ability to easily view the added data that was provided using the add data button  246  as described above. 
         [0085]    Save button  254  preferably allows a user to save a copy of the capture on the local device  220 . Markers, such as markers  242  and  244  are also saved along with any data added using the add data button  246 . 
         [0086]    CLR or color button  255  provides an automatically assessed measure of the gem color. The color is assessed by comparing the color in the capture to a local or remote database of gem colors. The user can optionally override the suggested color and choose a different color. 
         [0087]    Clarity button  256  provides an automatically assessed measure of the gem clarity. In the case of a diamond the clarity grades include: Flawless (FL), Internally Flawless (IF), Very, Very Slightly Included (VVS1 and VVS2), Very Slightly Included (VS1 and VS2), Slightly Included (SI1 and SI2), and Included (I1, I2, and I3). Similarly, clarity grades for other types of gems cold be automatically assessed. 
         [0088]    Based on the inclusions pointed out by the user using markers, such as markers  242  and  244 , and based on size data provided using the add data button  246 , the app preferably suggests a clarity grade. The user can optionally override the suggested grade and choose a different grade. Optionally app scans capture  230  for inclusions and suggests a clarity grade without the need for the user to mark the inclusions. 
         [0089]    Optionally, app determines the size of the gem following selection of size button  253  based on markers on the tweezers  212  or based on a calibration determined by the size of lens  122  or based on distance of the gem from the lens  122  measured by the camera or based on a combination of these. Optionally, the cut and/or the weight are provided using the add data button  246 . Optionally, the cut is determined automatically by comparing the capture to a local or remote database of cuts after selecting cut button  257 . Optionally, the weight in carats is calculated based on the size and cut after selecting weight button  259 . Optionally, the assessment of clarity, color, cut, weight and size are all performed automatically based on the capture without the need for user input. 
         [0090]    In addition the app provides other indicators and data including: 
         [0091]    The date  258  and time  260  of the local viewer which are optionally displayed on the capture and which may be stored with the capture to validate the capture date and time; 
         [0092]    Loupe connection indicator  262  provides confirmation that loupe  110  is wirelessly connected to mobile device  220 . If loupe  110  is not connected then the user will optionally be guided through the process of connection. 
         [0093]    While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made
