Paper Abstract

Conventional color TV pick-up systems, which have interline CCD image sensors with color filter array, have poor picture fidelity, due to factors such a luminance/chrominance spurious signals, image lag, and so on. In this paper, a new color coding method (improved line sequential complete color difference signal method) combined with a new CCD operation (quasi-field integration mode) is proposed to realize a single-chip color camera with well-balanced performance; no visible horizontal spurious color and no image lag. To certify the advanced performance, the single-chip color camera was experimentally fabricated using a 384(H)><490(V) pixel CCD sensor with complementary color filter array. The high fidelity reproduced images with no visible spurious color, a 56 dB signal-to-noise ratio, and low image lag, comparable to that for the field integration mode, were achieved. The newly proposed technologies are attractive for use with electronic still cameras for such application fields as office automation document readers, as well as to use with video cameras.
