Digital charge-coupled device color TV system for endoscopy

The paper describes the system consisting of a highly sensitive remote CCD camera head and a processing/control module. Specially designed virtual phase CCD has staggered pixel arrangement ensuring the vertical and horizontal resolution about 250 TV lines with the chip size of 2, 8 X 3 mm2. The system utilizes successive field color encoding (field sequential color method). The signal processing/control module comprises a real-time digital interpolator and video-frame memory. The image processor hardware and software provide image acquisition, treatment, distribution, and other functions.
