Abstract

A portable video animator device for creating a real-time animated video signal by combining a real-time video signal with animation data includes a video input device for inputting a real-time video signal, an image input device for inputting animation image data, a host processor for selecting animation image data representing an animated image from the input animation image data and a real-time processor for rendering the selected animation image data with the real-time video signal to produce a real-time video signal.

Claims

1. A portable video animation device for creating a real-time animated video signal by combining a real-time video signal with animation image data, comprising:

video input means for inputting a real-time video signal;

image input means for inputting animation image data, said animation image data including object outline data;

host processor means for selecting animation image data representing an animated image from said input animation image data; and

real-time processor means for rendering object outline data of said selected animation image data and combining said rendered object outline data with said real-time video signal to produce a real-time animated video signal.

2. A portable video animation device according to claim 1, wherein said real-time image processor means comprises real-time processor means for rendering animation image data, and colour transformation means, connected to said real-time processor means, which receives said rendered animation image data and creates said real-time animated video signal from said rendered animation image data and said real-time video signal.

3. A portable video animation device according to claim 2, wherein said colour transformation means is connected to said host processor means and setup and control information for said colour transformation means is alterable by said host processor means.

4. A portable video animation device according to claim 3, wherein said colour transformation means comprises a RAMDAC device.

5. A portable video animation device according to claim 1, wherein said animation image data comprises quadratic polynomial fragments.

6. A portable video animation device according to claim 1, wherein said image input means for inputting animation image data includes a plurality of memory storage housing means, each of which is adapted to receive a detachable memory storage device containing animation image data representing an animated image.

7. A portable video animation device according to claim 6, wherein said detachable memory storage device comprises a non-volatile memory card.

8. A portable video animation device according to claim 6, wherein said detachable memory storage device stores a system code used in the operation of said host processor means.

9. A portable video animation device according to claim 6, wherein said image input means for inputting animation image data further comprises detection means for detecting the presence of said detachable memory storage device.

10. A portable video animation device according to claim 6, further comprising a touch panel for inputting animation image data which is sensitive to a user'"'"'s touch and which transmits data relating to a location of said input animation image data to said host processor means.

11. A portable video animation device according to claim 10, wherein said touch panel is mounted over one of said plurality of memory storage housing means.

12. A portable video animation device according to claim 1, wherein said real-time processor means comprises a video coder means for converting said rendered animation image data to a real-time video signal.

13. A portable video animation device according to claim 1, wherein said real-time processor means comprises a video selector means for selecting between said real-time video signal and said rendered animation image data.

14. A portable video animation device according to claim 13, wherein said selector means determines said selection based on the colour of said rendered animation image data.

15. A portable video animation device according to claim 1, further comprising a genlocking means for producing synchronization signals from said real-time video signal, wherein said real-time processor means is connected to said genlocking means and uses said synchronization signals to produce said rendered animation image data.

16. A portable video animation device according to claim 1, further comprising data input means connected to said host processor means, said data input means comprising:

fade out signal input means which, upon activation, causes progressively greater portions of rendered animation image data to be included in said real-time animated video signal;

fade in signal input means which, upon activation, causes progressively lesser portions of rendered animation image data to be included in said real-time animated video signal; and

over signal input means which, upon activation, eliminates the animated portion of said real-time animated video signal at the beginning and end of said real-time animated video signal.
