Abstract

A new device and method allows simple transformation of a high resolution video image, still or full motion, into a number of segments, each of which can be converted to a standard NTSC or PAL television frame. Each frame can be encoded with information such as segment location and possibly time or other information and then stored or transmitted as a standard television signal. The original high resolution video image can be reconstructed by selecting each television frame and using the encoded information to reassemble the segments. The reconstructed image has full original resolution but, depending on the image, may not be able to reproduce motion at full speed.

Claims

1. A video image system comprising:

means for dividing a high resolution video image into a selectable plurality of segments,

means for converting each said segment to a standard television frame, and

means for encoding information about the relative position of each said segment in the high resolution video image,

wherein said means for dividing a high resolution video image into a selectable plurality of segments comprises a zooming scan converter.

2. The video image system of claim 1 further comprising means for selecting a number of segments comprising said selectable plurality of segments.

3. A video image system comprising:

means for dividing a high resolution video image into a selectable plurality of segments,

means for converting each said segment to a standard television frame, and

means for encoding information about the relative position of each said segment in the high resolution video image, and

a means for scaling each said segment to fit a standard television frame.

4. The video image system of claim 3 further comprising a means for interpolating adjacent pixels as part of said means for scaling.

5. The video image system of claim 3 further comprising a means for selectively scaling each said segment independently in a selected one dimension of horizontal and vertical dimensions.

6. A method of converting a high resolution video image, said method comprising:

providing a high resolution video image,

dividing said high resolution video image into a selectable plurality of segments,

converting each said segment into a standard television frame,

encoding information about the relative position of each said segment in said high resolution video image,

wherein said dividing a high resolution video image into a selectable plurality of segments comprises using a zooming scan converter.

7. The method of claim 6 wherein said selectable plurality of segments comprises a first number of segments for a first image of a high resolution video image, and further comprising providing means for providing a second image of a high resolution video image with a second number of segments where said second number of segments differs from said first number of segments.

8. A method of converting a high resolution video image, said method comprising:

providing a high resolution video image,

dividing said high resolution video image into a selectable plurality of segments,

converting each said segment into a standard television frame,

encoding information about the relative position of each said segment in said high resolution video image, and

scaling each said segment to fit a standard television frame.

9. The method of claim 8 further comprising interpolating adjacent pixels as part of said scaling.

10. The method of claim 8 further comprising selectively scaling each said segment independently in a selected one dimension of horizontal and vertical dimensions.
