Abstract: A frame-rate conversion system having an interpolation mode and a synchronization mode. The synchronization mode is selected when temporal interpolation confidence is and images can be retimed without dropping or repeating of images. The interpolation mode is selected when the measure of temporal interpolation confidence is high or repeating of images. Images are exchanged between a temporal interpolator and a buffer at an exchange rate which is varied in the interpolation mode to optimise the buffer occupancy for retiming of images without dropping or repeating of images in s subsequent synchronization.

Abstract: A frame-rate conversion system having an interpolation mode and a synchronisation mode. The synchronisation mode is selected when temporal interpolation confidence is and images can be retimed without dropping or repeating of images. The interpolation mode is selected when the measure of temporal interpolation confidence is high or repeating of images. Images are exchanged between a temporal interpolator and a buffer at an exchange rate which is varied in the interpolation mode to optimise the buffer occupancy for retiming of images without dropping or repeating of images in s subsequent synchronisation.

Abstract: To detect the presence of the two constituent images of a stereoscopic image within an image frame, a row of vertically-averaged pixels is derived from the upper half of the frame and compared with a second row of vertically-averaged pixels derived from the lower half of the frame. Similarly, a column of horizontally-averaged pixels is derived from the left half of the frame and compared with a column of horizontally-averaged pixels derived from the right half of the frame.
