Definitions

  • the present design relates to the projection of stereoscopic images, and in particular to reducing the effects of image leakage between left eye and right eye views, also referred to as crosstalk or “ghosting.”
  • Stereoscopic images are created by supplying the viewer's left and right eyes with separate left and right eye images showing the same scene from respective left and right eye perspectives. This is known as plano-stereoscopic image display.
  • the viewer fuses the left and right eye images and perceives a three dimensional view having a spatial dimension that extends into and out from the plane of the projection screen.
  • Good quality stereoscopic images demand that the left and right eyes are presented independent images uncorrupted by any bleed-through of the other eye's image.
  • stereoscopic selection or channel isolation must be complete. Stereoscopic selection can be accomplished to perfection using isolated individual optical paths for each eye, as in the case of a Brewster stereoscope. But when using temporal switching (shuttering) or polarization for image selection, the left channel will leak to some extent into the right eye and vice versa. The effect of this leaking is referred to as ghosting or crosstalk.
  • the present design seeks to address the issue of ghosting or crosstalk in a projected plano-stereoscopic motion picture environment. It would be advantageous to offer a design that enhances or improves the display of projected plano-stereoscopic motion pictures or images by reducing the crosstalk associated with such motion picture or image displays over designs previously made available.
  • a method for reducing ghost images in plano-stereoscopic image transmissions comprises establishing a plurality of expected ghosting profiles associated with a plurality of predetermined regions on a screen, and compensating for leakage in each predetermined region of a projected left eye image and a projected right eye image by removing an amount of ghost images leaking from the projected left eye image into the projected right eye image and from the projected right eye image into the projected left eye image.
  • a system for reducing ghost images in plano-stereoscopic image transmissions comprising a processor configured to receive the quantity of ghost artifacts and compute ghost compensation quantities for left eye images and right eye images.
  • the processor is further configured to remove an amount of actual image ghost artifacts leaking from a projected left eye image into a projected right eye image and from the projected right eye image into the projected left eye image.
  • the processor is configured to compute ghost compensation quantities for each of a plurality of zones, each zone corresponding to a region on a screen having an expected ghosting profile associated therewith.

  • FIG. 16 is a flowchart overview of operation of the present design.
  • FIGS. 17A-17F illustrate a segmented approach to ghost or ghost artifact compensation.
  • Preferred embodiments of the present design focus on large screen projection for entertainment, scientific, and visual modeling applications.
  • Such projection alternates the left and right image on the same screen area using temporal switching or polarization to select the appropriate images for each eye.
  • temporal switching which may be combined with polarization modulation
  • the display alternately transmits left and right eye images, and an electro-optical or similar polarization modulator is employed as part of the selection system to direct the appropriate image to the appropriate eye.
  • the modulator is best located at the projector and used in conjunction with analyzer glasses worn by audience members.
  • An alternate method is to use shuttering eyewear and dispense with the polarization switching approach. Selection devices are synchronized with the frame or field output of the projector to ensure that the frame or field can be perceived by the appropriate eye.
  • crosstalk results from a variety of sources, including the imperfect polarization modulation of the displayed image, a timing mismatch between polarization switching and the frame or field output of the display, the imperfect phase of the switch, allowing the wrong eye to leak through at the beginning or end of the frame, imperfect or leaking analyzers for viewing the polarized light, polarization state contamination caused by projection screen depolarization; polarization state contamination caused by airborne dust or dust on the port glass or modulator surface, and, in a linear polarizer selection system, relatively slight rotation of the analyzer glasses.
  • the present design addresses these sources of crosstalk in projection applications through an empirical calibration process characterizing the crosstalk specific to the projection equipment, image polarization or shuttering equipment, projection screen, viewer image selection equipment, and environment of a given installation. This process yields “ghosting coefficients” that characterize the measured crosstalk and are used to compensate image data at the projection site to provide installation-specific crosstalk cancellation.
  • Crosstalk is a linear phenomenon that affects each part of the image to the same proportion.
  • Crosstalk may be color dependent in so far as the primary colors that make up the image may have different crosstalk characteristics. In such cases each color may be compensated individually.
  • the present design may be applied to the class of displays in which the entire image area is addressed or displayed simultaneously.
  • the predicted ghosting is uniform across the entire screen, and characterization of crosstalk is preferably done by making a single measurement of crosstalk for each primary color to obtain a complete characterization with a single coefficient for each primary color.
  • Alternative embodiments may utilize displays in which the display is written to the screen in lines, segments, or blocks. Where the image is displayed in segments, the ghosting depends on the timing of the display of the segment, related to the switching speed of the modulator or shutter and their temporal characteristics. For segmented displays, characterization may be done for each segment, or for a sample of segments and then interpolated for the other segments.
  • the present design may also be applied in systems where the level of ghosting is different in different areas across the screen.
  • the system creates a segmented ghosting map where different ghost coefficients are applied in different areas of the screen. This is particularly applicable with polarized projection on silver screens, where the level of ghosting tends to be highly dependent on the projection angle and the viewing angle of the images.
  • Linear polarization has higher extinction but greater angular dependency of the polarizer with respect to the analyzer and shows degradation when the viewer tips his head to one side
  • circular polarization selection has lower extinction but is far more forgiving with regard to head tipping.
  • Using circular polarization for image selection can exhibit low crosstalk comparable to crosstalk obtained when employing linear selection.
  • Using linear polarization for image selection in accordance with the present design can provide an improved head tilting range comparable to that obtained when circular polarization selection is employed.
  • FIGS. 1A, 1B and 1 C show drawings of typical systems for stereoscopic projection. Aspects of each system contribute to the crosstalk as described below.
  • FIG. 1A is a two-projector system in which projectors 101 , 102 independently project left and right eye images modulated by corresponding linear or circular polarizers 103 , 104 .
  • One source of ghosting in this system is incomplete conservation of polarization that allows a residual component to leak to the eye whose channel is nominally blocked.
  • Light is reflected from a projection screen 105 .
  • Projection screen 105 preferably conserves the polarization of the light projected thereon. In actual practice the screen will to some extent depolarize the incident light, resulting in further ghosting.
  • Glasses 106 that are used to analyze the polarized light are imperfect and also contribute to ghosting.
  • FIG. 1B shows a single projector system employing a polarization modulator 108 , such as a Projector ZScreen® by StereoGraphics®, located in the projected beam.
  • a stereoscopic source drives projector 107 and provides parallel left eye and right eye channels or left and right eye channels in sequence on a single input. However formatted, the end result is frames projected in a sequence of left-right-left-right, and each particular frame may be sequenced to repeat (e.g. L 1 , R 1 , L 1 , R 1 , L 2 , R 2 , L 2 , R 2 , L 3 , etc.).
  • the projected beam passes through modulator 108 which switches polarization states in synchrony with the frame rate of the projector.
  • the system images the projected beam on the viewing screen 109 and the viewer observes the screen through passive polarized analyzer glasses 110 .
  • a primary cause of ghosting is imperfect polarization of the analyzer glasses 110 .
  • the depolarization artifact exhibits a color dependency, resulting in more ghosting in one color than another.
  • imperfect synchronization or phasing of the modulator with respect to the field rate may result in ghosting.
  • a switching time on the order of hundreds of microseconds may be required for a change in state. If a field or frame is projected during this transitional period, ghosting will be introduced.
  • FIG. 1C shows a variation of the single projector system.
  • the projector 111 projects left and right frames in sequence to the projection screen 113 as described above.
  • No modulator is used in the optical path at the projector and instead of switching polarization the viewer wears active glasses 114 , such as CrystalEyes® by StereoGraphics.
  • the active glasses 114 switch a liquid crystal shutter worn over each eye between a transmissive and a blocking state in synchrony with the projected left and right eye images. Switching is controlled by a wireless sync signal emitter 112 that communicates with the glasses via a communication medium, such as infrared or radio frequency, to switch them in sync with the frame output.
  • a communication medium such as infrared or radio frequency
  • FIG. 2A shows another system somewhat similar to that of FIG. 1C , using a direct view display 201 instead of a projected display.
  • the viewing screen alternately displays left and right eye views, and the system synchronizes active shuttering glasses 202 by a wireless or wired communication link 203 with the frame rate of the display.
  • FIG. 2B illustrates a system similar to that of FIG. 1B using a polarization modulator, such as the Monitor ZScreen® by StereoGraphics, covering the display.
  • the display 204 is viewed through the modulator 205 synchronized with the frame rate of the display 206 .
  • Passive polarized glasses 207 are used to select the appropriate image for each eye.
  • FIGS. 3A-3E illustrate the effect of ghosting and the basic principle of its correction.
  • FIG. 3A shows original uncompensated left eye and right eye images that form an image pair for creating a stereoscopic perception.
  • FIG. 3B shows the images actually perceived by the viewer's eyes when crosstalk creates ghost images during viewing of the image pair using one of the systems as described above, or the uncompensated views received by the viewer's eyes.
  • FIG. 3C shows the isolated ghost components, where the isolated components are to be subtracted from each eye's image from FIG. 3B .
  • the right eye image of FIG. 3B shows a left side image and a right side image, and the left side image is the image desired to be retained/transmitted.
  • FIG. 3A shows original uncompensated left eye and right eye images that form an image pair for creating a stereoscopic perception.
  • FIG. 3B shows the images actually perceived by the viewer's eyes when crosstalk creates ghost images during viewing of the image pair using one of the systems as described above,
  • FIG. 3C shows the isolation, in the right eye image, of the ghosted image, here the right side image, that is to be subtracted from the right eye total image of FIG. 3B .
  • FIG. 3D shows compensated images, where the ghost image perceived at each eye is subtracted from the original image to be provided to the opposite eye.
  • FIG. 3E shows the left eye image and right eye image actually perceived when the compensated images of FIG. 3D are projected and viewed through the same system that originally caused perception of the images of FIG. 3B through the display of the images of FIG. 3A .
  • the systems identified in FIGS. 1A, 1B , 1 C, 2 A and 2 B introduce different degrees of ghosting, depending on the quality and implementation of the components used in the system.
  • the amount of ghosting produced by a given installation of a given system is preferably measured empirically to characterize the unique ghosting characteristics of that system.
  • measurements are preferably made for each primary color (i.e. each individual subpixel color) of the projection system. In a conventional display system, this involves characterizing each of the three color channels (red, green, blue) that combine to form the color image.
  • analogous processes apply. Because the factors that produce ghosting are linear effects, single point per color characterizations may be made to predict the ghosting of the image as a whole.
  • the basic process for characterizing the ghosting or crosstalk in a given system is to use test patterns that provide a full luminance (white or a primary color) image for one eye and a zero luminance (black) image for the other eye. These images are displayed or projected by the system in L-R-L-R sequence. While a test pattern is displayed, the amount of light passing through the left and right eye portions of a pair of analyzer glasses located in a normal use position can be measured. The amount of light arriving at each eye location in response to the test patterns empirically characterizes the effects of all sources of crosstalk in the optical path between the projector and the viewer's eyes.
  • FIGS. 4A and 4B illustrate a process for characterizing ghosting using test patterns as described above.
  • FIG. 4A shows the use of a test pattern that provides full luminance to the left eye and zero luminance to the right eye.
  • a luminance meter 400 may be placed behind a pair of analyzer glasses 402 to measure the luminance at each respective eye position.
  • the luminance meter 400 may be a hand-held device that has a photosensing element for receiving light input and measuring circuitry for measuring and displaying or outputting data characterizing the luminance received by the photosensing element. Examples include the Photo Research PR650 and the Minolta CL-100. Since the left and right eye images of the test pattern are displayed in an alternating fashion, the luminance meter value represents an average over time of the luminance received over many projection cycles.
  • the left eye will receive full luminance and the right eye will receive zero luminance.
  • the right eye will receive some light from the full luminance left eye image as a result of the various crosstalk factors discussed above. Consequently the luminance at the right eye image will typically be a non-zero value. This is referred to herein as the leakage luminance.
  • the luminance measured at the left eye provides a baseline full luminance measurement to be used as described below.
  • FIG. 4B shows the use of a test pattern that provides zero luminance to the left eye and full luminance to the right eye. Using the luminance meter, measurements are made again at both the left eye and right eye positions. In response to this test pattern, a non-zero leakage luminance is typically measured at the left eye, while a baseline full luminance value is measured at the right eye.
  • the full luminance images are primary color images, and measurements as described above are made for each separate primary color, a feature available in various photosensing devices.
  • the system may calibrate using a model of a specific theater or other computer simulation, or may simply make assumptions about the proposed environment and create GCs based on expected viewing conditions.
  • a ghosting coefficient (GC) for each eye channel may be calculated by dividing the leakage luminance by the full luminance.
  • the ghosting coefficients GC provide a characterization of the crosstalk from one eye to the other that is created by the particular equipment used in the particular installation where the measurements were made. Where ghosting is color dependent, a separate ghosting coefficient is calculated for each primary color.
  • leakage luminance may be computed in each of the red, blue, and green color realms as 10, 15, and 5, respectively, with total or full luminance values of 100, 100, 100.
  • the GC for red (GCR) would be 0.10, or 10 per cent, representing 10 leakage luminance divided by 100 full luminance values.
  • Blue and green ghosting coefficients in this example would be a GCB of 0.15 and a GCG of 0.05.
  • the ghosting coefficients are used to compensate images in a manner that reduces the inherent crosstalk of the display system through cancellation, such that the final images perceived by the eyes exhibit reduced or imperceptible ghosting. More specifically, the ghosting coefficients are used to calculate ghosting components of the type illustrated in FIG. 3C , which are then subtracted from original images to yield compensated images as illustrated in FIG. 3D . When displayed, these images are perceived in the manner illustrated in FIG. 3E .
  • R f is the final compensated image for the right eye
  • R i is the original image for the right eye
  • L f is the final compensated image for the left eye
  • L i is the original image for the left eye
  • GC is the ghosting coefficient
  • the system calculates compensated sub-images for each primary color using the ghosting coefficient corresponding to each color.
  • a ghosting coefficient may be employed that is slightly larger than the coefficient measured using analyzer glasses that are aligned in a non-tilted position, as a certain amount of overcompensation can increase the acceptable head tilt range without creating perceptible negative ghosting.
  • FIG. 5 shows a process flow for producing right and left eye images that are compensated for the ghosting effects of a given system.
  • the process receives left eye image data 500 and right eye image data 501 as inputs.
  • Most digital image representations are non-linear, using either a power law (gamma) representation or a log representation, whereas the ghosting factors operate in the linear realm. Therefore, at point 502 , the process initially transforms the left and right eye image data by applying a linear transformation. In general, the linear transformation is preceded by an offset and normalization of the pixel values.
  • a black level offset (usually 64 in 10 bit representation) may be subtracted from the image received, followed by application of an exponential value (usually between 2.2 and 2.6) to the resultant image, and then multiplication by a scaling factor to fill the usable range (bitdepth) of the processor performing the calculations.
  • the system computes the ghost contribution from each eye image at point 504 using the formulas and coefficients discussed above.
  • the ghost contribution calculated for each images is then subtracted at point 506 from the original opposite eye image to yield compensated linear image data.
  • the compensated linear images may be converted back into a non-linear form by applying the inverse of the linear transformation applied above at point 508 .
  • Application of the inverse to convert back to non-linear form involves setting the range of representation and applying the non-linear transformation and offset.
  • the output of this processing is compensated right and left eye images 510 and 511 .
  • the display device may not be required to put the image representation back into a non-linear representation since the linear image data may be fed directly to the image display elements of the display device.
  • blocks 508 may not be needed and the output of blocks 506 may be applied directly to the image display elements of the display device and may be displayed.
  • ghost compensation may be performed in both real-time and non-real-time implementations. Examples of each are provided in FIG. 6 , which shows a postproduction environment where stereoscopic content is finished for viewing at other locations (e.g. cinemas).
  • FIG. 6 shows a postproduction environment where stereoscopic content is finished for viewing at other locations (e.g. cinemas).
  • One approach illustrated in FIG. 6 takes the original, uncompensated two-view or plano-stereoscopic images from a postproduction finishing system 600 and performs real-time ghost compensation 602 between the postproduction finishing system 600 and the reviewing projector 604 . This provides the ability to review the results of ghost compensation in real-time, and allows the reviewer to experiment with various levels of compensation.
  • a second approach for mastering is to use a non real-time process to render the ghost compensation into the images.
  • This system provides an off-line processor 606 that saves a ghost compensated master 608 which may be supplied later for viewing.
  • the ghost compensated master may be used for internal review or may be used as a master for producing distribution copies of the content.
  • the ghosting coefficients used in the compensation processing are typically selected to be an average of the estimated ghosting coefficients present in various viewing installations, as opposed to a value optimized for a specific installation.

To perform this, particularly when three components such as red, green, and blue are employed and ghost removal occurs for each component of every pixel.

  • the computing device executes a calibration application that automates the test pattern display and analysis and the setting of ghosting coefficients described herein.
  • FIG. 14B illustrates a high level process flow of the calibration application and its interaction with other system devices.
  • the calibration application sends a command to the video server to initiate the first eye test pattern, i.e. either the pattern that provides full luminance to the left eye or the pattern that provides full luminance to the right eye. While it is assumed here that the test pattern image data is resident in the video server, in alternative embodiments the calibration application may also supply the test pattern image data to the video server along with any commands necessary to cause the server to execute the test pattern.
  • luminance signals are received from the luminance meters. From these signals, the system takes and stores luminance readings.
  • the calibration application then issues a command to the video server to initiate the second eye test pattern, i.e. the test pattern for the eye opposite to that of the first test pattern.
  • Luminance signals are again received from the luminance meters and readings are taken and stored. The process of initiating test patterns and taking readings is repeated as necessary to obtain readings for all primary colors of the projector or all pertinent parameters employed in the ghost compensation, such as luminance/chrominance, etc.
  • the calibration application computes the ghosting coefficients of the left eye and right eye channels in the manner described above.

For example, if a region, including a pixel, has a red GC of 0.3, the value of 0.3 and the coordinate of that pixel may be transmitted to the compensation module, and similar red coefficients for all regions or pixels in the image are transmitted, typically indexed by region or pixel numbers or locations. Similar GC values may be transmitted for green and blue in the manner discussed.
  • FIGS. 15A and 15B illustrate an improvement in head tilting range that may be achieved in a system using linearly polarized images.
  • Uncompensated linear polarized systems allow only a small head tilt before unacceptable ghosting occurs. For example, in a system where the linear polarizers have extinction of greater than 1000:1 and the screen maintains polarization to 99%, just 3 degrees of head tilt can induce ghosting of 75:1, and the ghost component becomes objectionable. This level of head tilt is difficult to maintain for many viewers. Using ghost compensation, it is possible to extend this range of tilting that results in acceptable viewing to approximately 8 degrees.
  • FIG. 15A shows the extinction versus head tilt for an uncompensated system.
  • the curve shows that an extinction ratio of 75:1 is achievable only at tilt angles of less than 3 degrees in either direction.
  • FIG. 15B shows the performance when moderate ghost compensation is applied.
  • the curve shows the effect of overcompensating, resulting in good extinction at zero degrees, and maintenance of at least a 75:1 extinction ratio within a head tilt range of 8 degrees in either direction. Note that when ghosting is overcompensated, negative ghosts are produced (dark ghosts). The absolute value of the ghost has been plotted for clarity of explanation.
  • ghost compensation in accordance with embodiments disclosed provides enhanced performance for circular polarization applications, enabling dynamic ranges comparable to those of linear polarization systems to be achieved.
  • FIG. 16 illustrates general operation of the current design.
  • point 1601 represents calibration of the system, wherein at a particular site implementation the methodology of measuring the ghosting for the setup is employed as discussed above, namely measuring the ghosting in the specific environment, modeling the environment, or employing other ghosting measurement techniques.
  • the result of the calibration 1601 may be termed a ghosting profile or expected ghosting profile.
  • the system begins processing by computing at least one ghost coefficient or ghost artifact coefficient based on the screen segments, regions, or zones, which may be based on the results from point 1601 calibration.
  • Each ghost artifact coefficient represents ghost artifacts leaking from the left eye image into the right eye image and from the left eye image into the right eye image.
  • Point 1603 represents applying at least one ghost artifact coefficient for a left eye projected image to a right eye projected image to form a compensated right eye projected image, and applying at least one ghost artifact coefficient for the right eye projected image to the left eye projected image to form a compensated left eye projected image.
  • Point 1604 signifies removing the compensated right eye projected image from the right eye projected image, and removing the compensated left eye projected image from the left eye projected image. The result is transmitted to the screen and represents a projected image having ghosting or ghost artifacts removed therefrom.
  • FIGS. 17A-17F illustrate the general approach to segmented ghost correction, wherein the screen area or a hypothetical/theoretical screen area is divided into a plurality of segments, regions, or zones.
  • FIG. 17A shows a typical projection layout in a movie theatre environment with the projector 1701 perpendicular to the screen 1702 . From a central viewing point, i.e. a seat located at the centerline of the theatre, the ghosting will be roughly symmetrical about the center point on the screen.
  • FIG. 17B shows a screen with a typical distribution of the intensity of the ghost image. These are shown in the figure as contour lines 1703 representing edges of regions or zones having equal ghost intensity. If the projector is not projecting perpendicular to the center of the screen, but off axis, the distribution of ghosting will shift on the screen, as shown in FIG. 17C , with the contour lines 1704 shifted off center.
  • the optimum correction for the theatre is created by characterizing the ghosting factor across the area of the screen, generally by sampling or modeling the amount of ghosting in each part of the screen and creating a segmented correction map. For example, if Red/Green/Blue components are treated separately, blue ghosting may be significant at an edge or all edges of the screen.
  • the blue GC at an outer region or zone, toward the edge of the image, may be 0.4, while at the center of the screen blue ghosting may not be as significant and may therefore have a smaller GC, such as 0.15.
  • Each zone may have different GCs or may employ different ghosting properties depending on the particular environment.
  • FIG. 17D illustrates how a screen may be broken into a grid 1705 for characterizing the ghosting, with sample points 1706 in the grid.
  • This grid may have a small number of sample points, or a very large number of points as might be captured by a digital camera or modeled by a sophisticated computer model.
  • the ghost factor map or GC map may be a set of constants or may be reduced to a mathematical equation or family of equations that characterize the ghost factor (intensity of the ghost) against each segment, or the calibration data may be stored as a table.
  • FIG. 17E illustrates a sample plot of the ghost correction factors generated by a sampling procedure such as that illustrated in FIG. 17D , where sample points 1707 make up the graph. The appropriate factor is applied to the corresponding area of the image.
  • the points may be characterized by the row in which the pixels reside, such as Rows A and C of FIG. 17D exhibiting the same profile in FIG. 17E .
  • Other profiles may be realized, such as groups of rows, columns, zones, or regions having similar or identical profiles, or all profiles may differ.
  • FIG. 17F illustrates the screen broken into vertical regions, zones, or strips 1708 where the same factor is applied on each strip.
  • the plot 1711 shows an example of how the ghost factor might vary across each vertical strip. The end result is a cleaner picture viewed in the specific environment, with less ghosting apparent to viewers in the theatre.
  • circuits, devices, processes and features described herein are not exclusive of other circuits, devices, processes and features, and variations and additions may be implemented in accordance with the particular objectives to be achieved.
  • devices and processes as described herein may be integrated or interoperable with other devices and processes not described herein to provide further combinations of features, to operate concurrently within the same devices, or to serve other purposes.
