Motion-Compensating Field Interpolation From Interlaced And Non-Interlaced Grids

Effects caused by sampling and motion compensating interpolation of television sequences containing translatory motion in the image plane are analyzed in the frequency domain. As a velocity-adapted lowpass filter possesses a "velocity passband", a precise motion-compensation is not required. Schemes for motion-compensating interpolation from non-interlaced and interlaced grids are proposed and investigated experimentally by means of moving zoneplate patterns. A novel scheme for interpolation from an interlaced grid preserves the full vertical resolution of the picture contents over a wide range of velocities.
