Abstract
A video sequence control system comprising: a video frame sequence component for providing video frames for display by a projector, the video frames having a sequence of at least one crosstalk reduction frame followed an image frames; and a synchronization control component, the synchronization control component communicatively coupled to an image capture device the synchronization control component providing a timing signal to synchronize image capture with the occurrence of the at least one crosstalk reduction frame in the video frame sequence.

A video sequence control system comprising:
- a video frame sequence component for providing video frames for display by a projector, the video frames having a sequence of at least one crosstalk reduction frame followed an image frames;
- a synchronization control component, the synchronization control component communicatively coupled to an image capture device the synchronization control component providing a timing signal to synchronize image capture with the occurrence of the at least one crosstalk reduction frame in the video frame sequence;
- and
- a signal converter communicatively coupled to the synchronization control component and the image capture device, the signal converter for modifying the timing signal provided by the synchronization control component.
A method of controlling the capture of video frames in a video frame sequence comprising the steps of:
- producing video frame sequences for display by a projector, wherein the video frame sequence include at least one crosstalk reduction frame followed by an image frames;
- producing a synchronization control signal, wherein the synchronization signal is communicatively coupled to an image capture device, wherein the synchronization control signal provides information regarding the occurrence of the at least one crosstalk reduction frame, wherein responsive to the synchronization control signal an image is captured by the image capture device;
- and
- modifying the timing signal provided by the synchronization control component.
A non-transitory computer readable storage medium having computer readable program instructions stored thereon for causing a computer system to perform instructions, the instructions comprising the steps of:
- capturing a first image of a display and a scene in front of a display, the image capture occurring when a projector for projecting a video frame sequence including at least one crosstalk reduction frame followed by n image frames on the display is projecting a crosstalk reduction frame;
- blending the captured first image with a corresponding image frame;
- and
- producing a synchronization control signal, wherein the synchronization control signal provides information regarding the occurrence of the at least one crosstalk reduction frame that is used to determine the time the first image is captured by an image capture device.
