Interlaced
Interlaced scanning refers to an electronic method of scanning video image devices in order to capture or display a 2 dimensional image. Its use reduces flicker without increasing frame rate. Video images are sliced up into a series of horizontal lines that are sequentially numbered. These lines are grouped into two sets called Fields. The Odd Field contains all the odd numbered lines while the Even Field contains all the even lines. Interlaced scanning creates a frame of video by scanning the odd, then the even field, and finally combining the two fields. When the two fields are combined, the result may contain distortions because subjects within the image may move during the time between the two field scans. Modern technologies do not rely on interlaced scanning and can avoid the resulting image distortion. These technologies rely on progressive scanning instead.
