Interlaced video 隔行扫描

（重定向自Interlaced scanning）
A screenshot from HandBrake, demonstrating the difference between deinterlaced and interlaced images.[6]

Picture of a moving car tire, interlace combing reduced by realigning the even and odd field on the X axis. The other field has been moved 16 pixels right, reducing the combing on the bumper and the tire outline, but the hub cap that has turned between the fields has notable combing.

Interlaced video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured at two different times. This enhances motion pe****tion to the viewer, and reduces flicker by taking advantage of the phi phenomenon.
