Definitions
- the present invention relates to a method and apparatus for producing stereoscopic images, in particular a method of displaying stereoscopic images on a standard TV or Computer monitor without apparent flicker.
- a method of displaying stereoscopic images on a standard TV or Computer monitor without apparent flicker In order to view the stereoscopic images the viewer wears a pair of glasses that substantially enable the full colour spectrum to be seen by each eye.
- BACKGROUND OF THE INVENTION In order for a viewer to see stereoscopic images it is necessary for the viewers eyes to view the subject matter from a slightly different perspective such that each eye sees a different view of the image.
- Several methods are currently used to display stereoscopic images on a TV or Computer monitor.
- the anaglyph system as practiced in the current art, depends upon the use of complementary colour filters placed in front of each eye.
- a red transmitting filter may be used for the left eye, and a blue and green (cyan) transmitting filter used for the right eye.
- a blue and green (cyan) transmitting filter used for the right eye.
- a current technique is to produce on a TV or Computer monitor full colour images of the left and right perspective's alternately.
- the screen is viewed through spectacles which permit each eye to receive only the image of the appropriate perspective.
- the spectacles typically consist of Liquid Crystal elements that alternately "shutter" each eye, hence the generic term shutter glasses.
- the problem with this system is that when used at the standard field rate of 50Hz for PAL and 60Hz for NTSC television images, substantial flicker is produced because the image received by each eye alternates with periods of darkness. In order for this system to be acceptable to a viewer the image needs to be electronically processed to double the frame rate to a minimum of 100Hz. At this speed the flicker is not noticeable. However, the video image is now no longer produced at a standard speed and can not be displayed on a normal TV or Computer monitor.
- An object of the invention is to provide a method and apparatus for producing a stereoscopic image in which the viewer is provided with a image which may include a substantially full range of colour information for each eye substantially without flicker, and preferably when viewed on a standard, unmodified, PAL or NTSC TV or Computer monitor. Another object of the invention is to provide such an apparatus which may be produced in a fully electronic form rather than the electromechanical configurations of the prior art. Another object of the invention is to provide such an apparatus at relatively low cost.
- the present invention provides: a method for displaying a stereoscopic image on a display apparatus having a predefined field frequency wherein: a first perspective of an image to be viewed by a viewers left eye is passed through a first filter having a first spectral component of a colour spectrum; a second perspective of an image to be viewed by a viewers right eye is passed through a second filter having a second spectral component of a colour spectrum; and said first and second spectral components are caused to alternate at a rate equal to an odd multiple of the field frequency of the display apparatus.
- the present invention utilises first and second spectral components that are complementary to each other. That is, a combination of the first and second spectral components would produce white light.
- the first spectral component may be red
- the second spectral component cyan or a combination of blue and green.
- the present invention will be further discussed with reference to this red and cyan combination, however, any colour and its complement could also be used. For example, blue and yellow, or alternatively green and magenta, may also be used.
- Figure 2 shows the progressive switching over two fields.
- Figure 3 shows the relationship between the driving voltage and colour transmission of a Chiral Smectic (CS) LCD Cell.
- CS Chiral Smectic
- Figure 4 shows a practical implementation of a stereoscopic viewing system using CS LCD Cells constructed as spectacles.
- Figure 5 shows the stereoscopic video format required to drive a decoder of the present invention.
- Figure 6 shows a possible configuration to enable a CS LCD cell to be driven at odd multiples of the field frequency.
- Figure 7 shows a possible decoder for use with the present invention.
- Figure 8a shows a possible switching means, in this case a multiplexer configured to transmit the red complement of the image to the left eye, and the cyan complement of the image to the right eye.
- Figure 8b shows the next instance following Figure 8a, wherein the multiplexer is configured to transmit the cyan complement of the image to the left eye, and the red complement of the image to the right eye.
- Figure 9a shows a typical frequency spectra of two complementary spectral components.
- Figure 9b shows a graph of a notch filter to address the cross talk of two complementary spectral components.
- Figure 9c shows a resultant frequency spectra of two complementary spectral components after application of a notch filter.
- the present invention could be combined with 2D to 3D conversion systems, it is primarily directed towards a system for receiving a 2D signal together with 3D data, whereby the 3D data enables a decoder to convert the 2D signal into respective left and right eye images for stereoscopic viewing by a viewer.
- FIG. 7 An example block diagram of a decoder in accordance with the present invention suitable for converting conventional analogue field sequential 3D, into a format suitable for use with colour sequential glasses is shown in Figure 7.
- the operation of this decoder is as follows:
- Incoming video which may be in composite or S-Video format is converted into 24bit RGB format using a video Analogue to Digital converter. Alternate fields are stored in two 256k x 24bit field stores such that field store 1 contains odd fields and field store 2 contains even fields.
- the 24bit RGB outputs from each field store are selected by a triple 8bit multiplexer that, assuming Red/Cyan encoding has been used, selects the outputs as shown in Figure 8. That is, at one instance the red component of an image is directed towards the left eye, whilst the cyan component of the image is directed towards the right eye, as can be seen in Figure 8a.
- the multiplexer switches such that the cyan component is fed to the left eye and the red component to the right eye, as can be seen in Figure 8b.
- the output from the multiplexer is fed into a video Digital to Analogue encoder, the resultant composite or S-Video output being displayed on a standard Television or computer monitor.
- a decoder for example a 16bit YUV with a colour space conversion into and out of the triple 8bit multiplexer could also be used.
- the timing generator can operate to switch the multiplexer at an odd multiple of the field rate, thereby enabling both eyes of the viewer to receive a substantially full colour spectrum and the image in 3D. That is, each eye views two spectral components of each field.
- the choice and type of decoder is not important. What is required is that the decoder be able to receive and process the 2D image and 3D data, spectrally filter both the left and right eye images with two distinct spectral components, whilst effectively switching the spectral components at an odd multiple of the field frequency, such that the alternate filtering of both spectral components results in a substantially full colour stereoscopic image.
- phase A the red component of the left perspective view is presented to the left eye and the cyan component of the right perspective view to the right eye.
- phase B the cyan component of the left perspective view is presented to the left eye and the red component of the right perspective view to the right eye.
- phase C the red component of the left perspective view is presented to the left eye and the cyan component of the right perspective view to the right eye.
- the three phases of the second video field are indicated in figure 2.
- Electro-optic switchable colour filters come in two basic varieties: birefringent colour filters and dichroic colour filters. Both types operate by linearly polarising light in a particular way that then allows the electro-optic means to manipulate those polarisations and transmit one colour at a time. The polarisation manipulation required entails either rotating the polarisation direction by 90° or leaving the direction unchanged. Both birefringent and dichroic filters were originally constructed with Kerr cells or Faraday rotators to control the polarisation, but today liquid crystal retarders provide the electro-optic function more conveniently.
- CS Chiral Smectic
- CS devices are switchable half-wave plates with a rotation angle of 45°. They are binary devices capable of switching between two orthogonal polarisation states. For an application of the present invention they may be constructed to switch between either red or cyan transmission. Transition times, between red and cyan, are small compared with the field flyback period of PAL and NTSC television standards.
- the cells are typically driven with bipolar +/- 5V DC balanced waveforms as illustrated in figure 3.
- transition CS LCD cells become available it is possible to reduce the visibility of the transitions to the viewer by changing the video line number that the cell switches from red to cyan or cyan to red on each field.
- the line number, and hence the physical position on the TV or Computer monitor screen the colour transition will not be so noticeable to the viewer. That is, assuming that switching of the cell from one spectral component to the other spectral component for each frame would normally take place on line x. Then to reduce the transition effect, the line on which switching occurs for each frame can be varied to take place on one or more adjacent lines, for example lines x, x+1 , x+2, ...x+n, may be used. Ideally, 5 to 10 different video lines can be used to switch the cell and thereby reduce the effect of the transitions.
- the video line numbers that the transitions take place on every field can be varied in a fixed sequence or on a pseudo random basis.
