-> Interlaced scan is a method of television scanning in which the transmitted image on the target of the television camera tube and the television frame on the screen of the picture tube are produced by a single scanning of two frame fields.

-> The odd lines are scanned and reproduced for the first field, and the even lines, which are positioned in the spaces between the lines of the first field, make up the second field.

-> When scanning of the second field has been completed, the beam is returned to the point where the scanning of the first field begins.

-> Drawbacks to interlaced scanning compared to progressive scanning include flicker, lower resolution and quality issues.

Interlaced scan is one of two methods used for "painting" a video image on an electronic display screen by scanning or displaying each line or row of pixels.
