Abstract
We have developed an experimental progressive-scanning HDTV color camera system that has three 2/3-inch-2.2M-pixels-CCDs. This CCD has a Frame-Interline-Transfer (FIT) structure and was for interlaced-scanning, but we successfully drive it in a progressive mode by means of "M-FIT" and "FIT-IT" driving method, where "M-FIT" transfers pixel charges separately in two groups of odd lines and even lines, and "FIT-IT" stores the even lines in its vertical-transfer-CCD after transferring the odd lines into its frame memory. We drive it in 148.5 MHz to reproduce sixty frames a second of a progressive-scanned picture. The limiting resolution was 1,000 TV lines in both the horizontal and vertical directions.
