Abstract:
A method for processing two fields of interlaced video, comprising:computing motion vectors describing motion of image characteristics from a field to another field of opposite sense; removing from the motion vectors an offset corresponding to one half of a line and having a sign according to an orientation of the y-axis of the image space and which field includes the top line; using the motion vectors to generate a sampling region at a desired output time; transforming the sampling region using the motion vectors to a sample time at one of the fields; transforming the sampling region using the motion vectors to a sample time at the other of the fields; determining a field sense of an output field to be generated at the desired output time; translating the transformed sampling region for the field with a field sense opposite the field sense of the output field by an offset of one half of a line and having a sign determined by an orientation of the y-axis of the image space and which field includes the top line; and generating the output field using the transformed and translated sampling regions and the input fields.
