Patent ID: 6842196

Claim:
A method for automatic correction of motion artifacts in an interlaced video image captured by an image recording camera comprising: capturing a complete frame of an interlaced video image, the complete frame having a first raster field and an interlaced second raster field, the first and second raster fields each having a plurality of pixels and pixels in the first raster field are offset from pixels in the second raster field; automatically correcting for camera motion, comprising determining whether the captured frame contains camera motion artifacts; performing auto-correlation on the first raster field with respect to the second raster field by locating optimal correlation values for X/Y coordinates for each pixel in the first raster field relative to a reference pixel in the second raster field using a repeating 3×3 convolution search to create a two-dimensional motion vector between each pixel in the first raster field and the reference pixel in the second raster field; automatically correcting for subject motion; and displaying an image corrected for camera motion and subject motion.
