Abstract :
A progressive scan CCD (charge coupled device) that features multiple-frame interline transfer (M-FIT) operation is described. This 2/3-inch 500-k (948*486)-pixel M-FIT CCD is implemented on the basis of a conventional 2poly-Si process, and has a 16:9 aspect ratio (switchable to 4:3), an 80-dB dynamic range, and 25-nA/1*sensitivity. A schematic diagram of an experimental device developed for the next-generation widescreen TV camera system is shown. Measured photoconversion characteristics are shown together with those for a conventional progressive scan CCD. A reproduced image of a resolution chart in which 480 TV-line resolution is achieved by the progressive scan is also shown.<>
