WHAT IS CLAIMED IS:

1. A process for producing a video signal for compatible stereoscopic viewing, comprising combining a selected chrominance component of a past video field with the complementary chrominance component of a current video field to produce a composite video signal including both said selected and complementary chrominance components.

2. A process for producing a video signal according to claim 1 , including varying the synchronization of said selected component relative to said complementary component to produce a composite video signal corresponding to an image having background objects which include preselected color fringes.

3. A process for producing a video signal according to claim 1 or 2, wherein said composite video signal also includes the luminance component of said current video field.

4. Apparatus for processing video signals in real time comprising
means for storing a digital representation of an incoming video signal corresponding to at least one past field,
means for producing a digital representation of a video signal corresponding to a current field, and
means for combining at least a portion of said stored video signal corresponding to said past field with at least a portion of the video signal corresponding to said current field to produce a composite video signal.

5. Apparatus for processing video signals according to claim 4, including means for varying the timing of said video signal portions relative to each other to create a preselected visual effect.

6. Apparatus for generating a video signal for compatible stereoscopic viewing with appropriately filtered glasses, comprising
decoder means for separating an incoming video signal into its luminance and complementary chrominance components,
an analog-to-digital converter for converting said luminance and complementary chrominance components into digital signals at a predetermined sampling rate,
field storage means for storing the digital signals corresponding to at least one past video field, and
means for combining (A) one of the chrominance signals stored in said field storage means for a selected one of said past video signals and (B) the other chrominance signal and luminance signal for the current field to produce an output video signal.

7. Apparatus according to claim 5, including means responsive to a comparison of the image of said preselected field with the image of the current field for controlling the synchronization of the read-out of said field storage means to said combining means to control selectively the color fringing of a portion of the image.

8. Apparatus according to claim 6 or 7, wherein said full storage means stores at least two past video fields and said means for combining said one chrominance signal of a selected past field.
