Another type of CCD imaging device in which the rows of charge are stepped down one at a time and processed straight away.

Also referred to as 2:1 interlaced video, interline transfer devices combine two fields to make up each video. If each field is scanned at 60Hz, the frame rate is necessarily 30Hz. (There are other interlacing schemes, but they are not used in standard industrial cameras.)

See interline-transfer CCD imager.

A technology of CCD design, where rows of pixels are output from the camera. The sensor's active pixel area and storage register are both contained within the active image area.
