Abstract
A method and apparatus for time multiplexing and demultiplexing two channels (102, 103) of picture information within a standard video channel (1726). The method is specifically designed for field sequential stereoscopic display applications, but may used for non-stereoscopic applications where conservation of bandwidth is desired.
Claims
1. A method for forming a flickerless, field- sequential stereoscopic image from first and second analog video signals, each analog video signal being encoded with sychronization information and color information, comprising: digitizing the video signals; decoding the digitized video signals; storing a first portion of each decoded digitized video signal in an odd video field and storing a second portion of each decoded digitized video signal in an even video field; multiplexing the video fields so as to generate a flickerless stereoscopic video image.
2. The method of claim 1, further comprising genlocking the analog video signals with respect to each other.
3. A method for time multiplexing a first analog video source signal and a second analog video source signal, including the steps of: synchronizing the horizontal and vertical relationship of said first analog video signal and said second analog video signal generating a first and a second digitized video signal from the first and second analog video source signals, respectively; separating horizontal and vertical sync timing edges from the first and second digitized video source signals; generating a first luma signal and a second luma signal by removing the chroma components of the first and second digitized video signals, respectively; generating a first pair and a second pair of chroma signals by decomposing the chroma components of the first and second digitized video signals, respectively; combining the first pair of chroma signals and combining the second pair of chroma signals; storing the first luma signal and the first pair of chroma signals in a first field memory, wherein each unit of storage in the first field memory comprises a single video field in which even and odd video fields are alternately stored; and storing the second luma signal and the second pair of chroma signals in a second field memory, wherein the second field memory comprises separate storage for even and odd video fields.
4. The method of claim 3, further comprising: filtering each of the first and second luma signals to eliminate noise and peak the luminance; increasing the bandwidth of each of the first and second pair of chroma signals; and converting each of the first and second luma signals and each of the first and second pair of chroma signals to analog signal levels.
5. The method of claim 4, further comprising generating a four fold interlaced video field sequence, wherein two of the interlaced fields correspond to odd and even video fields of the first field memory, respectively, and two of the interlaced fields correspond to odd and even video fields of the second field memory, respectively, and wherein the sequence is chosen so as to generate a flickerless video image.
6. The method of claim 5, wherein the signals stored in the first field memory correspond to a left perspective image and the signals stored in the second field memory correspond to a right perspective image, and wherein the sequence of video fields is left-odd, right-odd, left-even, right-even.
7. The method of claim 5, wherein the sequence is chosen to maximize vertical image size.
8. The method of claim 5, further comprising centering the video image within a viewing area.
9. The method of claim 8, wherein the centering step comprises incrementally shifting one image then incrementally shifting the other image so as to alternately adjust the relative positions of the images.
10. The method of claim 9, further comprising storing the amount of relative adjustment of the images in non-volatile storage.
11. The method of claim 9, wherein the shifting of images generates fringe areas in the viewing area having no stereoscopic video signal content, and further comprising blanking the fringe areas.
12. The method of claim 4, wherein each of the storing steps are suspended so as to generate a still image from the analog signal levels.
13. The method of claim 3, wherein the each of the storing steps comprises writing data to the field memory in ascending address order.
14. The method of claim 3, wherein the each of the storing steps comprises writing data to the field memory in descending address order.
15. An apparatus for processing analog video source signals from a first camera and a second camera in order to generate a real time display output and composite and component record outputs, wherein the first camera provides a first source signal and the second camera provides a second source signal, each source signal being encoded with sychronization information and color information, comprising: means for digitizing the source signals,- means for decoding the digitized source signals,- means for storing a first portion of each decoded digitized source signal in an odd video field; means for storing a second portion of each decoded digitized source signal in an even video field; means for multiplexing the video fields so as to generate a flickerless stereoscopic video image.
16. An apparatus as in claim 15, further comprising means for synchronizing the horizontal and vertical relationship of the source signals.
