Title: Systems and methods for improved production and presentation of video content

Description:
RELATED APPLICATIONS 
     The present application claims the benefit of U.S. Provisional Application Ser. No. 63/145,488 filed on Feb. 4, 2021, the entire disclosure of which is expressly incorporated herein by reference. 
    
    
     BACKGROUND 
     Related Art 
     Video content is an increasingly important communication medium for several fields including, but not limited to, academia (e.g., lectures, labs, distance education networks, etc.), business (e.g., meetings, trainings, etc.), and television (e.g., broadcasts). The production and presentation quality of video content can greatly impact the effectiveness of the video content in achieving desired goals. For example, a clear visual and audio representation of a presenter (e.g., a professor, a lab technician, an executive, a trainer, a news broadcaster, etc.) and the use of visual elements (e.g., text and graphics) can facilitate effective communication. However, the process of producing and presenting video content can be complex and require significant resources and time due to the required amount of audio/video equipment, coordination and editing time. Additionally, known approaches for producing video content utilize one or more light sources that can generate light reflections visible to video equipment (e.g., a camera). This can be problematic when light reflects from the eyes or eyeglasses of a presenter or any transparent material between the camera and the presenter. Conventional techniques for mitigating these reflections include moving the one or more light sources outside of a zone within which there is a reflection path from the one or more light sources, off a reflective surface and back to the camera or by diffusing the light emitted by the one or more light sources to soften a harshness or intensity of a reflection. However, these mitigation techniques can require additional studio space and video equipment. 
     As such, what is needed is a reduction in the current complexities, resources and time to produce and present video content. 
     SUMMARY 
     The present disclosure relates to systems and methods for improved production and presentation of video content. 
     Embodiments of the present disclosure can facilitate the production and presentation of video content by an efficient and intuitive workflow that adds visual elements to camera-shot video in real-time while providing visual feedback to a presenter to coordinate his/her interaction with these visual elements. Embodiments of the present disclosure can provide visual cues (e.g., a traceable element) that are only visible to a presenter to guide a presentation and/or eliminate light source reflections during video content production without the need for additional studio space and video equipment. Thus, embodiments of the present disclosure overcome the disadvantages of conventional video presentation and production technology by providing solutions in the form of systems and methods that, for example, can automatically, seamlessly and efficiently provide for the production and presentation of visually appealing and engaging video content that dynamically incorporates additional visual elements and/or visual feedback in real-time. 
     In one embodiment, a system is disclosed that includes a transparent panel. The system receives a camera signal indicative of image data of a scene that can include, for example, a user positioned behind the transparent panel, and receives an overlay signal having at least one visual element. The at least one visual element can be one or more of a text, a logo, an application window, a presentation slide, a drawing, a figure, a diagram, a chart, and a graph. The system processes the camera signal and the overlay signal to generate a first signal. In particular, the system flips the image data of the camera signal from left to right and transforms the at least one visual element utilizing, for example, a keying function. The keying function can be one of a chrominance keying function, a luminance keying function and shape keying function. The system displays a processed image of the first signal on a first display. The processed image is indicative of the at least one visual element overlaid on the image data of the scene. The system also displays an application window of a second signal on a second display. Based on a user input, the system relocates the application window from the second display to the overlay signal. The system displays the application window on the first display by transforming the application window utilizing the keying function and overlaying the transformed application window in the processed image of the first signal. 
     In another embodiment, the system comprises a transparent panel having an input responsive interface. The input responsive interface can be a capacitive system, a resistive system, an inductive system, an infrared beam system, and/or a gesture based sensor system. The system receives a camera signal indicative of image data of a scene that can include, for example, a user positioned behind the transparent panel, and receives, in response to a user input on the transparent panel, an input responsive signal indicative of user input data. The user input data can be one or more of text, a drawing, a figure, a diagram, a chart, and a graph. The system processes the camera signal and the input responsive signal to generate a first signal. In particular, the system flips the image data of the camera signal from left to right, generates a digital representation of the user input data and transforms the digital representation utilizing, for example, a keying function. The keying function can be one of a chrominance keying function, a luminance keying function and shape keying function. The system displays a processed image of the first signal on a first display. The processed image is indicative of the user input data overlaid on the image data of the scene. The system also displays an application window of a second signal on a second display. Based on a user input, the system relocates the application window from the second display to an overlay signal associated with the first signal. The system displays the application window on the first display by transforming the application window utilizing a keying function and overlaying the transformed application window in the processed image of the first signal. 
     In another embodiment, the system comprises a transparent panel, a sheet having a controllable opacity, and a projector having a shutter. The sheet can be fixed to a portion or an entirety of a surface of the transparent panel or can be integrally formed with the transparent panel. The system receives, from a camera positioned in front of the transparent panel, a camera signal indicative of image data of a user positioned behind the transparent panel. The system also receives an overlay signal having at least one visual element. The system controls a display of the at least one visual element, projected by the projector, on the sheet by controlling an opacity of the sheet and the shutter of the projector such that the at least one visual element is visible to the user positioned behind the transparent panel and not visible to the camera. In particular, the system drives a first state for a first predetermined period where the sheet is semi-opaque and the shutter is open to display the at least one visual element on the semi-opaque sheet, and drives a second state for a second predetermined period where the sheet is transparent and the shutter is closed to preclude displaying the at least one visual element on the transparent sheet. Further, the system cycles between the first state and the second state such that the at least one visual element is visible to the user in the first state and the camera captures an image without the at least one visual element in the second state. In particular, the system cycles between the first state and the second state at a rate to enable persistence of vision to yield an impression to the user that the at least one visual element is continuously displayed. 
     In another embodiment, the system comprises a transparent panel having a substrate and a projector that projects polarized light. The system receives, from a camera positioned in front of the transparent panel, a camera signal indicative of image data of a user positioned behind the transparent panel. The system also receives an overlay signal having at least one visual element. The system controls a display of the at least one visual element, projected by the projector, onto the substrate of the transparent panel such that the at least one visual element is visible to the user positioned behind the transparent panel and not visible to the camera. In particular, the system provides for coordinating the polarization of the projected polarized light with a polarizing filter of the camera such that the projected polarized light is not visible to the camera. 
     In another embodiment, the system comprises a transparent panel having a plurality of lighted pixels. The system receives, from a camera positioned in front of the transparent panel, a camera signal indicative of image data of a user positioned behind the transparent panel. The system also receives an overlay signal having at least one visual element. The plurality of lighted pixels can be oriented to provide light in a direction of the user that is not visible to the camera. The system controls a display of the at least one visual element on the plurality of lighted pixels such that the at least one visual element is visible to the user positioned behind the transparent panel and not visible to the camera. 
     In another embodiment, the system comprises a transparent panel having a first plurality of lighted pixels and a second plurality of lighted pixels. The system receives, from a camera positioned in front of the transparent panel, a camera signal indicative of image data of a user positioned behind the transparent panel. The system also receives an overlay signal having at least one visual element. The first plurality of lighted pixels can be oriented to provide light in a direction of the user that is not visible to the camera and the second plurality of lighted pixels can be oriented in a direction of the camera. The system controls the display of the at least one visual element on the first plurality of lighted pixels such that the at least one visual element is visible to the user positioned behind the transparent panel and not visible to the camera and a display of a different at least one visual element on the second plurality of lighted pixels.

     DETAILED DESCRIPTION 
     The present disclosure relates to systems and methods for improved production and presentation of video content as described in detail below in connection with  FIGS.  1 - 14   . 
     Turning to the drawings,  FIG.  1    is a diagram illustrating an embodiment of the system  10  of the present disclosure. The system  10  can include a central processing unit  12  (e.g. a hardware processor) of a computer system (e.g., a video content presentation system), a server  20  (e.g., a service for applications or services), and a database server  22 . The hardware processor  12 , the server  20  and the database server  22  can communicate via a communication network (not shown). The hardware processor  12  could include, but is not limited to, a personal computer, a laptop computer, a tablet computer, a smart telephone, a server, an embedded computer system (e.g., a processor of a presentation system), a microprocessor, and/or a cloud-based computing platform. 
     The system  10  also includes system code  14  (e.g., non-transitory, computer-readable instructions) stored on a non-transitory computer-readable medium and executable by the hardware processor  12  or one or more computer systems. The processor  12  executes the system code  14  which generates a presentation signal. In particular, the system code  14  could include various custom-written software modules that carry out the steps/processes discussed herein including, but not limited to, a controller  16  having a mirroring device  18   a , a video switcher  18   b , a signal duplicator  18   c  and a recording module  18   d . The system code  14  could be programmed using any suitable programming or scripting languages including, but not limited to, C, C++, C#, Java, JavScript, Python, Ruby, Swift, and/or any other suitable language. Additionally, the system code  14  could be distributed across multiple computer systems in communication with each other over a communication network, stored within hardware, and/or stored and executed on a cloud computing platform and remotely accessed by a computer system in communication with the cloud computing platform. As discussed in greater detail in connection with  FIGS.  3 - 7   , the system code  14  can communicate with the server  20  and the database  22  via a communication network, which could be stored on the same computer system as the system code  14 , or on one or more other computer systems in communication with the system code  14 . It should be understood that the controller  16  could be provided on the same system as the hardware processor  12  or be remote from the same system as the hardware processor  12 . 
     Still further, elements of the system  10  can be embodied as a customized hardware component such as a field-programmable gate array (“FPGA”), application-specific integrated circuit (“ASIC”), embedded system, or other customized hardware component without departing from the spirit or scope of the present disclosure. It should be understood that  FIG.  1    is only one potential configuration, and the system  10  of the present disclosure can be implemented using a number of different configurations. 
       FIG.  2    is a diagram illustrating another embodiment of the system  40  of the present disclosure. As shown in  FIG.  2   , the system  40  can include the hardware processor  12 , the controller  16 , a camera  54  having a first polarizing filter  70 , a microphone  55 , a light source  66  having a second polarizing filter  72 , first and second displays  44  and  46  within a view of a user such as presenter  42 , a transparent panel  68  having integrated light sources  74 , and first and second backdrops  62  and  64 . 
     The system  40  generates and transmits a plurality of signals including a monitor signal  48 , an overlay signal  52 , a camera signal  56 , a presentation signal  60 , a data signal  76  (e.g. a live audio and video output data signal), a projection signal  82 , a touch input data signal  84 , and a graphics signal  86  as described in further detail below in connection with  FIG.  7   . In particular, the hardware processor  12  can transmit an overlay signal  52  having at least one visual element (e.g., text or a figure) to the controller  16 . The hardware processor  12  can also transmit a monitor signal  48  to the second display  46 . The second display  46  can be a monitor and can allow the presenter  42  to interact with various computer applications, windows and controls displayed on the second display  46 . Alternatively, the second display  46  can be a display of a computer (e.g., a laptop). The camera  54  transmits a camera signal  56  to the controller  16  that corresponds to a scene imaged by the camera  54 , which can include, for example, the transparent panel  68 , the presenter  42 , and/or the backdrop  62 . The camera signal  56  can include an audio component provided by the microphone  55  or the microphone  55  can transmit an independent audio signal to the controller  16 . The camera  54  captures an image of the transparent panel  68  and the presenter  42  against the first backdrop  62 . The first backdrop  62  can comprise a material having a smooth pattern or solid color. Embodiments of the first back drop  62  can be a dark color, e.g., such as black. The controller  16  can transform image data of signals and merge signals in real time to generate a presentation signal  60 . For example, the controller can transform a visual element of the overlay signal  52  and overlay the transformed visual element on a signal  80  which is a left right mirrored version of camera signal  56  to generate the presentation signal  60 . The presentation signal  60  can be transmitted to and displayed on the first display  44 . The first display  44  can be a monitor and provides the presenter  42  with visual feedback of a presentation while presenting. Additionally, the presenter can interact with a visual element of the presentation signal  60  displayed on the first display  44  by gesturing to the visual element or annotating the visual element via the transparent panel  68 . 
     The presenter  42  can write and/or draw on the transparent panel  68  utilizing a writing utensil (e.g., a marker) and/or a stylus. The controller  16  left-right mirrors the camera signal  54  such that text and/or figures written in a normal orientation and legible to presenter  42  while writing on the transparent panel  68 , appear to the presenter  42  in the same orientation on the first display  44 . The transparent panel  68  can be comprised of a transparent material (e.g., glass or acrylic). As such, a presenter  42  can write and/or draw information (e.g., text, figures, and annotations) on the transparent panel  68  while being visible to and making eye contact with the camera  54 . The integrated light sources  74  of the transparent panel  68  can be positioned on two edges of the transparent panel  68  or extend around a perimeter of the transparent panel  68  and illuminate a presenter  42  positioned behind the transparent panel  68 . 
     It should be understood that the transparent panel  68  can include another light source or lighting system that emits light into one or more edges of the transparent material thereby causing the emitted light to travel through the transparent panel  68  via total internal reflection. As such, a presenter  42  can utilize a marker to mark a surface of the transparent panel  68  which disrupts this total internal reflection and causes light to escape from the transparent panel  68  at a location of a marking. Further, if the marker contains fluorescent dye, then a marking can glow brightly and provide an image contrast in front of the presenter  42 . 
     The presenter  42  can also utilize a touch-responsive system  69  (e.g., a touch-responsive interface) integrated into the transparent panel  68  to generate handwritten information (e.g., text, figures, or annotations). The touch responsive system  69  can be, but is not limited to, an inductive, resistive, infrared beam or gesture-based sensor system. Interactions between the presenter  42  and the touch-responsive interface are transmitted to the hardware processor  12  via a touch input data signal  84 . The touch input data signal  84  can be utilized by an application (e.g., a drawing or sketching program) as a control input (e.g., a mouse or stylus) to generate a digital representation of the handwritten information. Additionally, this control input can be utilized as a multi-touch input to move and resize an application window being executed on the hardware processor  12 . A digital representation of handwritten information can be edited, saved, deleted, recalled, and manipulated in various ways. A digital representation of handwritten information can also be transmitted via the overlay signal  52  for real time addition to the presentation signal  60  (as shown in  FIGS.  8 A-C ) or can be transmitted via a graphics signal  86  which is processed similarly to the overlay signal  52  for addition to the presentation signal  60 . 
     It should be understood that the system  40  need not include the transparent panel  68 . For example, the system  40  can include an alternate touch-input device (not shown) that can display the overlay signal  52  to a presenter  42 . A presenter  42  can utilize the touch-input device to draw over and annotate visual elements of the overlay signal  52  in the same way as described above in relation to a touch responsive system  69  of the transparent panel  68 . 
     The system  40  can eliminate light source reflections during video content production without the need for additional studio space and video equipment. For example, the integrated light sources  74  of the transparent panel can illuminate a presenter  42  and obviate a need for the light source  66  which can generate reflections off of eyeglasses worn by the presenter  42  and/or the transparent panel  68 . Additionally, the second backdrop  64  can eliminate reflections from one or more objects located behind the camera  54  (e.g., object  78 ). The second backdrop  64  can comprise a dark color material having a smooth pattern or solid color and can prevent noticeable reflections of differential contrast objects. Further, an enclosure can be constructed using the material of the first and second backdrops  62  and  64  to enclose a lens of the camera  54  up to a perimeter of the transparent panel  68  to eliminate external reflections. The enclosure simplifies a configuration and size of a studio. It should be understood that the enclosure can include the first and second displays  44  and  46 . The first and second displays  44  and  46  can emit light which can generate reflections on the transparent panel  68  that are visible to the camera  54 . As such, the light emitted from the first and second displays  44  and  46  can be polarized and the polarizing filter  70  of the camera  54  can remove the generated reflections. 
     If the transparent panel  68  is not utilized, or even when it is, light emitted by the light source  66  may still be desired to illuminate the presenter  42 . Light emitted by the light source  66  can be vertically polarized by passing through the polarizing filter  72 . The polarizing filter  70  is positioned in front of the camera  54  and can be oriented to block vertically polarized light to prevent reflections of the vertically polarized light from entering a lens of the camera  54 . Other orientations and types of polarization can be employed. 
     Additionally, the system  40  can control an orientation of polarization of light emitted from multiple sources. For example, the system  40  can orient the first and second displays  44  and  46  to emit light polarized in the same direction such that reflections of the first and second displays  44  and  46  off of the transparent panel  68 , the eyes or eyeglasses of the presenter  42  or other reflective surfaces can be eliminated by orienting the polarizing filter  70  of the camera  54 . Alternatively, the system  40  can polarize light emitted by the light source  66  in the same direction as the first and second displays  44  and  46 . The light source  66  allows for rotational adjustability of polarizing media such that the polarizing filter  70  of the camera  54  can remove the reflections of two or more sources (e.g., the light source  66  and first and second displays  44  and  46 ). 
       FIG.  3    is a flowchart  100  illustrating overall process steps carried out by the system of the present disclosure. Beginning in step  102 , the system processes a touch input data signal  84  (user input data) to generate a graphics signal  86  having at least one transformed digital representation (e.g., a graphic) of the touch input data (e.g., text or a figure). The touch input data signal  84  can be based on a touch input of the presenter  42 , can include an application or digital annotation, and can be partially transparent. Step  102  is discussed in greater detail in connection with  FIG.  4   . Then, in step  104 , the system processes the overlay signal  52  to generate a transformed overlay signal. The transformed overlay signal can be partially transparent. Step  104  is discussed in greater detail in connection with  FIG.  5   . In step  106 , the system processes a camera signal  56  to generate a mirrored camera signal (e.g., left-right mirrored). It should be understood that the system can modify a background of the mirrored camera signal. Step  106  is discussed in greater detail in connection with  FIG.  6   . 
     Then, in step  108 , the system  10  merges the graphics signal  86 , the transformed overlay signal, and the mirrored camera signal to generate a presentation signal  60 . The graphics signal  86 , the transformed overlay signal, and the mirrored camera signal can be merged via various techniques such as layering or adding color and luminance data of each signal. In step  110 , the system transmits the presentation signal  60 . The presentation signal  60  can be transmitted to be recorded, streamed, and/or displayed. For example, the presentation signal  60  can be output to the first display  44  and/or can be streamed or transmitted to other display devices and/or to a storage device via a communication network. It should be understood that the process  100  can include more or fewer steps and/or that one or more of steps  102 ,  104 , and  106  can be omitted and that these steps need not be executed sequentially in the order as shown in  FIG.  3    but may be executed sequentially in a different order or in parallel. 
       FIG.  4    is a flowchart illustrating step  102  of  FIG.  3    in greater detail. In step  120 , the system receives a touch input data signal  84 . Then, in step  122 , the system routes the touch input data signal  84  to a control or drawing application for processing. In step  124 , the control or drawing application generates a digital representation of the touch input data (e.g., text or a drawn figure) and that digital representation is transformed. For example, the control application can move, resize, or otherwise interact with the touch input data. In another example, one or more data components (e.g., a background color, a control menu, a color palette) of the drawing application can be modified or removed, such as being made transparent. The removal process can utilize a chrominance or luminance keying function or a shape key to omit an element based on a location thereof. In step  126 , the system generates a graphics signal  86  having a transformed digital representation (e.g., text or a figure). 
       FIG.  5    is a flowchart illustrating step  104  of  FIG.  3    in greater detail. In step  140 , the system receives an overlay signal  52 . The overlay signal  52  can include one or more visual elements (e.g., text, a logo, an application window, a presentation slide, a drawing, a figure, a diagram, a chart, and a graph) as an overlay and the one or more visual elements can be digitally added to a presentation signal  60 , which can then be recorded, streamed, and/or displayed. For example, the presentation signal  60  can be output to the first display  44  for display on the first display  44  and/or can be streamed or transmitted to other display devices or storage devices via a communication network. In step  142 , the system utilizes a luminance key function to transform particular pixels (e.g., black pixels) of the overlay signal  52  to be transparent. It should be understood that alternative key functions could be utilized such as a chrominance key or a shape key. In step  144 , the system  10  generates a transformed overlay signal including the one or more visual elements. 
       FIG.  6    is a flowchart illustrating step  106  of  FIG.  3    in greater detail. In step  160 , the system receives a camera signal  56  corresponding to the scene imaged by the camera  54 . In step  162 , the system generates a mirrored camera signal by flipping image data of the camera signal from left to right. Then, in step  164 , the system  10  utilizes a key function to remove and replace a background of the mirrored camera signal. The key function can be one of a chrominance key, a luminance key or a shape-based key to remove a specific background color or a specific section of a camera-captured image. A replacement background can be added to the background of the remaining image. In step  166 , the system generates a transformed mirrored camera signal. 
       FIG.  7    is a diagram  180  illustrating the controller  16  of  FIG.  1   . The controller  16  can be a video controller and can include a mirroring device  18   a , a video switcher  18   b , a signal duplicator  18   c , and a recording module  18   d . The controller  16  can receive, generate and transmit signals including the overlay signal  52 , the camera signal  56 , the presentation signal  60 , the data signal  76 , the mirrored camera signal  80 , the projection signal  82 , the touch input data signal  84 , and the graphics signal  86  as described in further detail below. The mirroring device  18   a  receives the camera signal  56  and mirrors the camera signal  56  horizontally (e.g., left to right) to generate a mirrored camera signal  80 . The mirroring device  18   a  transmits the mirrored camera signal  80  to the video switcher  18   b . It should be understood that the mirroring device  18   a  can be obviated by utilizing a mirror in front of the camera  54  such that the camera  54  is rotated 90 degrees from a viewing axis and the mirror is placed 45 degrees from an optical axis of the camera  54 . 
     The video switcher  18   b  receives and transforms the overlay signal  52 , the mirrored camera signal  80 , and the graphics signal  86  and generates and transmits the presentation signal  60  and the projection signal  82 . In particular, the video switcher  18   b  transmits the presentation signal  60  to the signal duplicator  18   c  and the projection signal  82  to a projector  264  (as shown in  FIGS.  10 A-B ) to be projected onto the transparent panel  68 . 
     As described in further detail below in connection with  FIGS.  10 A-B , the projection signal  82  and visual information (e.g., a visual element) thereof can be projected onto the transparent panel  68  such that the visual information can be visible or not visible by the camera  54  (e.g., the camera signal  56 ). The visual information can include, but is not limited to, text (e.g., notes), a cue (e.g., a presentation transition), and a traceable element (e.g., a figure stencil). For example, a presenter  42  can utilize notes or cues that are not captured by the camera  54  (e.g., not included in the camera signal  56 ) and are not visible to a presentation viewer, to control and guide a presentation. In another example, a presenter  42  can utilize a figure stencil projected onto the transparent panel  68  to draw the figure based on the projected figure stencil. Additionally, a presenter  42  can utilize a shape projected onto the transparent panel  68  to effectively annotate the shape which can be included in overlay signal  52 . As such, the projection signal  82  can be utilized as a guidance tool by the presenter  42  to efficiently and naturally reference and/or annotate visual information and draw figures on the transparent panel  68  compared to referencing the visual information as displayed on the first display  44  via the presentation signal  60 . Therefore, rather than relying on the presentation signal  60  displayed on the first display  44  for spatial awareness and/or on unguided movements, the projection signal  82  provides for building presenter  42  confidence and improving overall spatial awareness and use of the transparent panel  68 . It should be understood that the projection signal  82  can be simply a duplicate of the overlay signal  52  or can be based on a combination of signal  52 , a processed output of the graphics signal  86 , and additional visual elements, all after treatments such as luminance, chrominance, or shape keying are applied as discussed previously 
     The signal duplicator  18   c  duplicates the presentation signal  60  into identical signals which are respectively transmitted to the first display  44  and the recording module  18   d . The presentation signal  60  is displayed on the first display  44  and can be viewed by a presenter  42  while presenting. The recording module  18   d  records the presentation signal  60  to storage media (e.g., removable storage media or database server  22 ). 
     The controller  16  can include a source to receive and add audio input signals from an audio source (e.g., microphone  55 ) to the presentation signal  60 . It should be understood that the hardware processor  12  can comprise the controller  16  and the elements and features thereof into a single unit with a single power cord for efficient deployment and use. Additionally, components of the system  40  (e.g., the camera  54 , the microphone  55 , the light source  66 , the first and second displays  44  and  46 , and the transparent panel  68  having the integrated light sources  74 ) can be configured to power on to a ready-to-record state via a single power on and power off control action by the presenter  42 . For example, the hardware processor  12  or controller  16  can include a single button to initiate and stop recording. As such, a presenter  42  can record video content incorporating a variety of visual elements without interacting with the controls of the components of the system  40  (e.g., the camera  54 ). The controller  16  can also include a live audio and video output data signal  76  which can be utilized by the hardware processor  12  or transmitted to a separate computer for live streaming to one or more external streaming or recording services. A streaming or recording service can be in communication with the hardware processor  12  via a local area network, wireless transfer, or internet protocols. 
       FIG.  8 A  is a diagram  200  illustrating the generation of a presentation signal  60 . As shown in  FIG.  8 A , the mirrored camera signal  80  is merged with visual elements (e.g., butterfly  88  and application window  90 ) of the overlay signal  52  to generate the presentation signal  60  displayed on the first display  44 . In particular, the overlay signal  52  is transformed by removing the black background thereof such that the butterfly  88  and application window  90  are isolated and can be overlaid in a foreground of the mirrored camera signal  80 . 
       FIGS.  8 B-C  are diagrams illustrating an example application of the system of the present disclosure. In particular,  FIGS.  8 B and  8 C  are diagrams  210  and  215  illustrating the translation (e.g., using a click-and-drag function) of an application window  90  of a monitor signal  48  displayed on a second display  46  to a presentation signal  60  displayed on a first display  44 .  FIG.  8 B  illustrates the monitor signal  48  and the presentation signal  60  in a left-right arrangement as seen by a presenter  42  when presenting. As mentioned above, the second display  46  can be a monitor and can be utilized to display one or more applications containing notes (e.g., application window  90 ), a live application (e.g., a video conferencing application), etc. The first display  44  can also be a monitor and can be utilized as a confidence monitor by the presenter  42  to view the presentation signal  60 . The presentation signal  60  can include one or more visual elements as viewed by the camera  54  such as the presenter  42  and written information  92  and one or more additional visual elements (e.g., butterfly  88 ) from an overlay source (e.g., overlay signal  52 ). 
       FIG.  8 C  illustrates the monitor signal  48  and the presentation signal  60  in a left-right arrangement as seen by a presenter  42  and the partial translation of the application window  90  of the monitor signal  48  displayed on the second display  46  to the presentation signal  60  displayed on the first display  44 . As shown in  FIG.  8 C , the application window  90  is transformed and dragged and dropped in real time during the translation process. In particular, a dark background of the application window  90  is removed and made transparent prior to being dragged and dropped onto the presentation signal  60 . 
       FIG.  9    is a diagram  220  illustrating a relationship between a set of signals of the system of the present disclosure. In particular,  FIG.  9    illustrates a monitor signal  48 , an overlay signal  52 , a presentation signal  60 , and a mirrored camera signal  80 . The monitor signal  48  is displayed on a second display  46  and the presentation signal  60  is displayed on a first display  44 . As shown in  FIG.  9   , the system can generate the presentation signal  60  by transforming and merging the visual elements (e.g., butterfly  88  and application window  90 ) of the overlay signal  52  with the mirrored camera signal  80 . 
     The hardware processor  12  can consider each of the monitor signal  48  and the overlay signal  52  as an external monitor type signal. Additionally, the hardware processor  12  can configure a display arrangement of the signals  48  and  52  such that the monitor signal  48  is positioned on the left of a left-right monitor arrangement and the overlay signal  52  is positioned on the right of the left-right monitor arrangement. It should be understood that other display arrangements (e.g., a vertically stacked top-bottom array) can be configured and that the display arrangement configuration is indicative of a physical arrangement of the first and second displays  44  and  46  as viewed by a presenter  42 . The hardware processor  12  can also configure a background of the overlay signal  52  to be a specific color (e.g., black) to facilitate desired image processing via luminance and chrominance keying operations. For example, the hardware processor  12  can utilize a luminance key function to transform each black visual element of an overlay signal  52  to be transparent and overlay the remaining visual elements on top of the mirrored camera signal  80  to generate the presentation signal  60 . Additionally, the hardware processor  12  can set a default image having a visual element (e.g., grid lines or a logo) as the background of the overlay signal  52 . In this way, the grid lines or logo can be a default addition of the overlay signal  52  when not superseded by another image or application positioned in front of the grid lines or logo. 
     As mentioned above, a presenter  42  can write text and/or draw figures on the transparent panel  68 . The presenter  42  can also interact with the hardware processor  12  while the first and second displays  44  and  46  are within view of the presenter  42 . For example, during a presentation, a presenter  42  can interact with various applications, files, and functions as shown on the second display  46  but not visible in the mirrored camera signal  60  as shown on the first display  44 . 
     Further, a presenter  42  can instantaneously relocate (e.g., using a click-and-drag function) an application or file window from the second display  46  to the first display  44 , with previously described transformations upon the application or file window occurring instantaneously. As such, the system provides for an application image to be merged with a live (e.g., low latency) camera image via a seamless, efficient and presenter friendly control method. Additionally, the system allows a presenter  42  to utilize the first display  44  for visual feedback because the presentation signal  60  as displayed on the first display  44  includes a real time view of the camera  54  (e.g., mirrored camera signal  80 ) and visual elements (e.g., butterfly  88  and application window  90 ) of the overlay signal  52  added thereto. For example, a presenter  42  can utilize the first display  44  for feedback to gesture towards and/or effectively annotate using the transparent panel  68  as if the contents of the presentation signal  60  (e.g., butterfly  88  and application window  90 ) are displayed on the transparent panel  68 . Additionally, it should be understood that the presentation signal  60  is indicative of studio produced video content in real time and, as such, the presenter  42  can utilize the first display  44  as a reference to determine whether the content, quality and appearance of the video content (e.g., presentation) is acceptable. 
       FIG.  10 A  is diagram  260  illustrating a presentation arrangement of an embodiment of the system of the present disclosure. In particular,  FIG.  10 A  illustrates a first state of a controllable opacity sheet  262  fixed to a surface of or integrally formed with the transparent panel  68  and a projector  264  configured to receive a projection signal  82  and project an image thereof onto the sheet  262 . 
     The sheet  262  has a controllable opacity. In particular, a presenter  42  can control the opacity of the sheet  262  and can view and interact with the projected image including a visual element  266  thereof. The sheet  262  can be fixed to a portion of the surface of the transparent panel  68  (as shown in  FIGS.  10 A and  10 B ) or an entirety of the surface of the transparent panel  68 . The projector  264  includes a polarizing filter  268  and a shutter  270 . The projector receives a projection signal  82  and projects an image thereof onto the sheet  262 . The shutter  270  can be controlled to open and close to omit a projected image of the projection signal  82  for predetermined periods of time. The opening and closing of the shutter  270  can be synchronized with an integral or external shutter of the camera  54 . The shutter  270  can be mechanical or can be comprised of a material of controllable opacity (e.g., an LCD) or may be integral to the projector. 
     As mentioned above, the first and second displays  44  and  46  can emit light which can generate reflections on the transparent panel  68  that are visible to the camera  54 . As such, the light emitted from the first and second displays  44  and  46  can be polarized and a polarizing filter  70  of the camera  54  can remove the generated reflections. Additionally, the polarizing filter  70  of the camera  54  and the polarizing filter  268  of the projector  264  can be each oriented such that light polarized by the filter  268  does not pass through the polarizing filter  70 . This coordinated management of polarization provides for the projected image of the projection signal  82  to be visible to the presenter  42  while simultaneously not being visible by the camera  54  (e.g., projection signal  82  is omitted from the image of the camera  54 ). 
     As shown in  FIG.  10 A , in the first state, the sheet  262  can be controlled/driven into a state of increased opacity for a predetermined period. In particular, an opacity of the sheet  262  can be fixed in a semi-opaque state for a duration of a presentation with one or more images of the projection signal  82  projected onto the sheet  262 . The camera  54  can record the one or more projected images, the presenter  42  and written information (e.g., text  92  and/or drawings) made on the transparent panel  68  by the presenter  42 . The written information is partially visible through and fully visible around the semi-opaque sheet  262 . 
     It should be understood that a digital overlay of projection signal  82  or overlay signal  52  can be added to a presentation signal  60  to provide for greater visibility of the components with high fidelity. It should also be understood that the projection signal  82  can be projected directly onto the transparent panel  68  without a controllable opacity sheet  262  affixed thereto. A presenter  42  can determine an opacity of the transparent panel  68  to provide a desired balance of clarity in the camera-collected image of the presenter  42  and the vibrancy of the projected image. Particles can also be fixed on a surface of the transparent panel  68  or within the transparent panel  68 . These particles provide for an image projected onto a transparent panel  68  surface proximate to the presenter  42  to be visible to the presenter  42  without being visible to the camera  54 . Light projected on these particles can be cyclically pulsed relative to a phase of a shutter of the camera  54 . 
       FIG.  10 B  is diagram  280  illustrating a presentation arrangement of an embodiment of the system of the present disclosure. In particular,  FIG.  10 B  illustrates a second state of the sheet  262  fixed to the surface of the transparent panel  68  and the projector  264  configured to receive the projection signal  82  and project an image thereof onto the sheet  262 . As shown in  FIG.  10 B , after a predetermined period, the sheet  262  can return to a state of decreased opacity and the projector  264  ceases to project light. During the second state, the camera  54  captures one image or frame of a video. Subsequently, the sheet  262  and projector  264  revert to the first state as shown in  FIG.  10 A . This process can repeat indefinitely. Cycling between the first and second states provides for the capture of high quality video without the presence of projected images while allowing a presenter  42  to view reference information for visual guidance (e.g., where to gesture and write). Additionally, cycling between the first and second states can be executed at a high frequency such that any flicker is imperceptible to the presenter  42 . A global timecode can be utilized to synchronize the equipment required to maintain a proper timing of these mutually exclusive states. 
     It should be understood that the controller  16  can execute signal processing to allow a portion of visual elements of the overlay signal  52  to be included in the projection signal  82  while also excluding those visual elements from the presentation signal  60 . For example, the controller  16  can provide for tracing guides or notes to be included in the overlay signal  52  and visible to the presenter  42  while excluding the tracing guides or notes from the presentation signal  60  such that the tracing guides or notes are not visible to a viewer of the presentation. This type of signal processing can utilize transformations based on particular chrominance or luminance values of pixels of the overlay signal  52 . In particular, the controller  16  can assign a particular color to a visual element that a presenter  42  wishes to be visible on the transparent panel  68  but not visible in the presentation signal  60  (e.g., the controller  16  removes the particular color before merging the overlay signal  52  with the presentation signal  60 ). Alternatively, the projection signal  82  projected onto the transparent panel  68  could be entirely different from the overlay signal  52 . 
     As described in further detail below in connection with  FIGS.  11  and  12   , the transparent panel  68  can comprise a transparent or translucent liquid crystal display (LCD) or an organic light-emitting diode (OLED) display having lighted pixels to display information in a direction of a presenter  42 . The projection signal  82  can be displayed using these lighted pixels and the lighted pixels can provide light in the direction of the presenter  42  that is not visible to the camera  54  (e.g., the camera does not capture the image). A high-fidelity version of overlay signal  52 , transformed to remove or alter a particular visual element thereof, can be integrated into the presentation signal  60 . Alternatively, the transparent panel  68  can include lighted pixels to provide light in a direction away from the presenter  42  that is visible to the camera  54  and to an in-person viewer. These lighted pixels may or may not be separate and separately controlled from the lighted pixels proximately facing a presenter  42 . 
       FIG.  11    is a diagram  276  illustrating an example transparent panel  68  of the system of the present disclosure. As shown in  FIG.  11   , the transparent panel  68  includes a plurality of lighted pixels  280  and a plurality of lighted pixels  282 . The plurality of lighted pixels  280  is oriented to face the presenter  42  and project light in a direction of the presenter  42 . As such, the plurality of pixels  280  do not project light in a direction of the camera  54 . The plurality of the lighted pixels  280  can be illuminated to display an image of the projection signal  82  to the presenter  42  thereby allowing the presenter  42  to reference or interact with the image. The plurality of lighted pixels  282  is oriented to face the camera  54  and project light in a direction of the camera  54 . As such, the plurality of lighted pixels  282  do not project light in a direction of the presenter  42 . The plurality of lighted pixels  282  can be illuminated to display an image of signal  278  which can be imaged by the camera  54  or, alternatively, viewed by a viewer from a side of the transparent panel  68  opposite from the presenter  42 . The projection signal  82  and the signal  278  can be different from one another. For example, projection signal  82  can include and provide tracing guidelines to the presenter  42  which are not included in the signal  278 . The projection signal  82  can also include visual elements (e.g., butterfly  88  and application window  90  as shown in  FIGS.  8 A-C  and  FIG.  9   ) which can also be included in the signal  278 . Each of the projection signal  82  and the signal  278  can include a digital representation of touch input data (e.g., text or a drawn figure) generated from an interaction of the presenter  42  with the transparent panel  68  via a stylus or touch interface. Alternatively, the projection signal  82  and the signal  278  can be identical signals. The signal  278  can also be a left-right mirrored version of the projection signal  82  such that a gesture of the presenter  42  towards an image of the projection signal  82  is viewed by the camera  54  as a gesture to the same image. It should be understood that the transparent panel  68  is transparent, despite the inclusion of the pluralities of pixels  280  and  282  therein, such that the camera  54  can image a scene including the presenter  42 . A size of each pixel of the pluralities of pixels  280  and  282  as shown in  FIG.  11    is not intended to be to scale thereby providing for substantial interstitial space between the pluralities of pixels  280  and  282  and rendering the panel  68  transparent. 
       FIG.  12    is a diagram  284  illustrating a lighted pixel  280  of the transparent panel  68  of  FIG.  11   . The lighted pixel  280  includes a light emitting element  286  and an opaque shroud  288 . The light emitting element  286  can be a light-emitting diode (LED), an organic light-emitting diode (OLED) or any suitable light emitting element. The light emitting element  286  emits light  290  in a controlled geometric range such that the emitted light  290  is visible to a presenter  42  but not visible to a camera  54 . The opaque shroud  288  surrounds the light emitting element  286  to limit a direction from which the emitted light  290  can be visible. It should be understood that each lighted pixel  280  can be configured to emit light equally in a direction of a presenter  42  and a camera  54 . 
       FIG.  13    is a diagram  300  illustrating a light source  302  of an embodiment of the system of the present disclosure. The light source  302  includes a plurality of light emitting elements  304  and can be shaped like a ring. The light emitting elements  304  can be light-emitting diodes (LEDs) or any suitable light emitting elements. The light source  302  can be positioned concentric about a lens of the camera  54  and can have an opening sufficiently sized so as not to obstruct a field of view of the camera  54 . A donut shaped polarizing filter  306  can be positioned in front of the light source  302  and can be freely rotated about the light source  302  to yield a desired orientation relative to the polarizing filter  70  positioned in front of the camera  54 . For example, if filters  70  and  306  are linearly polarized, then the polarizing filter  306  can be oriented with polarization perpendicular to the polarization of the polarizing filter  70 . When the polarizing filters  70  and  306  are appropriately oriented, reflections of emitted light can be removed from a camera captured image. 
       FIG.  14    is a diagram  400  illustrating hardware and software components of a computer system  402  on which the system code  14  of the present disclosure can be implemented. The computer system  402  can include a storage device  404 , computer software code  406  (e.g., system code  14 ), a network interface  408 , a communications bus  410 , a central processing unit (CPU) or microprocessor  412 , a random access memory (RAM)  414 , and one or more input devices  416 , such as a keyboard, mouse, etc. It is noted that the CPU  412  could also be one or more graphics processing units (GPUs). The computer system  402  could also include a display (e.g., an LCD, a cathode ray tube (CRT), etc.). The storage device  404  could comprise any suitable, computer-readable storage medium such as a disk, non-volatile memory (e.g., read-only memory (ROM), erasable programmable ROM (EPROM), electrically-erasable programmable ROM (EEPROM), flash memory, FPGA, etc.). The computer system  402  could be a networked computer system, a personal computer, a server, a smart phone, a tablet computer, etc. It is noted that the server need not be a networked server, and indeed, could be a stand-alone computer system. 
     The functionality provided by the present disclosure could be provided by computer software code  406 , which could be embodied as computer-readable program code stored on the storage device  404  and executed by the CPU  412  using any suitable, high or low level computing language and/or executable files, such as Python, Java, C, C++, C#, etc. The network interface  408  could include an Ethernet network interface device, a wireless network interface device, or any other suitable device which permits the computer system  402  to communicate via a network. The CPU  412  could include any suitable single-core or multiple-core microprocessor of any suitable architecture that is capable of implementing and running the computer software code  406 . The RAM  414  could be any suitable, high-speed, RAM typical of most modern computers, such as dynamic RAM (DRAM). 
     Having thus described the system and method in detail, it is to be understood that the foregoing description is not intended to limit the spirit or scope thereof. It should be understood that the embodiments of the present disclosure described herein are merely exemplary and that a person skilled in the art can make any variations and modification without departing from the spirit and scope of the disclosure. All such variations and modifications, including those discussed above, are intended to be included within the scope of the disclosure. What is desired to be protected by Letters Patent is set forth in the appended claims.
