Chrominance Moire Reduction Using CCM(Correlative Coefficient Multiplying) Signal Interpolation in Single-Imager Color video Camera.
Naoki Ozawa · The Journal of The Institute of Image Information and Television Engineers · 1992
A signal interpolation method forchrominance moire reduction in images from a singleimager color video camera has been developed.This method (Correlative Coefficient Multiplying : CCM) interpolates one color signal using a second color signal multiplied by a correlation coefficient related to the ratio of low frequency components of the two color signals.It produces excellent quality video images with reduced chrominance moire and high resolution, reducing the harmonic component of the chrominance signal.An effective application of the CCM interpolation method is explained, and still images reproduced by the CCM interpolation from a color imager with normal complimentary filter are evaluated.
