抄録

Composite video signal being digitized, it is always affected by voltage gain and offset of the accompanying analog circuitries. Further, because of non-ideal low pass and band Pass filters., signal coupling exists between luminance and chrominance signals. Therefore, the data obtained from A-to-D converters should be compensated by some means. This paper deals with four incremental models of the digitizing process. They are tested by experiments. The degree of precision is expressed by the three kinds of color differences, including a measure of the just noticeable color difference based on the MacAdam' s ellipses, in order to evaluate the models and to get the most reasonable one.
