Digital video system for assembling video sequences
View Patent ↗An image processing system ( 10 ) obtains image sequences and assembles a presentation therefrom. The system has a camera ( 12 ) for capturing image sequences, a random-access electronic memory ( 16 ) for temporary storage of the image sequences, an input reader for accepting pre-programmed instructions from a first storage medium, a control panel with a display ( 18 ) for viewing image sequences ( 64 ) and presenting pre-programmed instructions to the operator and an operator interface for accepting responses to the pre-programmed instructions. A control logic processor ( 20 ) executes pre-programmed instructions and arranges the presentation from the captured image sequences stored in random-access electronic memory ( 16 ), according to operator responses. An output writer records the presentation onto a storage medium.
1. A digital video camera for producing composite motion video frames, comprising:
an image sensor for capturing user-captured motion video frames which do not include camera motion;
a processor for processing the user-captured motion video frames to produce the composite motion video frames,
a memory for storing pre-stored background motion video frames and control information which defines the camera motion of the background video frames, wherein the pre-stored motion video frames and the control information were stored prior to capturing the user-captured motion video frames; and
the processor responsive to the user-captured video motion frames, the control information and the pre-stored motion video frames to automatically process the user-captured motion video frames to produce processed user-captured motion video frames having digitally simulated camera motion and to produce the composite motion video frames by combining the processed user-captured motion video frames and the pre-stored motion video frames so that the composite motion video frames include subject content from the user-captured motion video frames and background content from the pre-stored motion video frames.
2. The digital video camera according to claim 1 wherein the simulated camera motion provides an apparent pan and zoom effect.
3. The digital video camera according to claim 1 wherein the simulated camera motion provides camera rotation.
4. The digital video camera according to claim 1 wherein the control information further include instructions to enable the processor to process the user-captured motion video frames to provide time-reversal.
5. The digital video camera according to claim 1 wherein the control information further include instructions to enable the processor to process the user-captured motion video frames to provide slow motion image frames.
6. The digital video camera according to claim 1 wherein the control information further include instructions to enable the processor to process the user-captured motion video frames to provide accelerated motion image frames.
7. The digital video camera according to claim 1 wherein the control information further include instructions to enable the processor to process the user-captured motion video frames to provide slow-motion forward frames followed by slow-motion time-reversal frames.
8. The digital video camera according to claim 1 wherein the control information further include instructions to enable the processor to process the user-captured motion-video frames to provide special effects including auto-rotoscope, image mirroring, or geometric distortions.
9. The digital video camera according to claim 1 wherein the memory stores a plurality of presentation themes that can be selected using an operator interface, each presentation theme having at least one associated pre-stored motion video frames.
10. The digital video camera according to claim 9 , wherein the operator interface is a touchscreen.
11. The digital video camera according to claim 1 , wherein the camera includes an integrated stand.
12. The digital video camera according to claim 1 , further including a wireless communication mechanism for receiving the pre-stored motion-video frames.
13. The digital video camera according to claim 1 , wherein the pre-stored motion video frames are event or theme based.
14. The digital video camera according to claim 13 , wherein the control information includes at least one prompt for the user to provide selections that identify the event or theme.
15. The digital video camera according to claim 1 , wherein the control information further includes prompting the user with suggestions for capturing the motion-video frames.
