High-definition television cameras show an increased amount of noise compared with conventional television cameras. This refers to the high bandwidth of an HDTV-camera. Different known filter structures are described. However, these methods cannot be used in a future HDTV system with its high quality requirements because they only remove noise for filtering in moving and nonmoving parts which decreases visibility of noise.
