What are the benefits of a Full Frame Transfer CCD versus an Interline CCD?
Interline CCD’s have traditionally been used in digital cameras and are either interlaced or progressive scan sensors. Interline chips are designed with a path or “highway” to move data. This highway takes up valuable real estate that could be used for image capture and reduces the size of the photodiode in each pixel. The E-1 Full Frame Transfer CCD transfers image data via a Vertical Charge Register that is a fraction of the size of an Interline highway. In fact, the active pixel area of the Full Frame Transfer CCD is about 1.5x larger than an Interline CCD of equal size. Using less of the pixel to transfer data means more space can be used to capture data for better image resolution. The Full Frame Transfer CCD uses more of the pixel area to actually act as a sensor with a wider aperture for the photodiode and larger pixel capture area. With its larger capacitor, a Full Frame Transfer CCD captures more electrons than a conventional Interline CCD to deliver higher sensitivity, higher
