Abstract
PURPOSE: To enable to make visible the fine color change, by limiting the upper limit of the frequency band of blue color signal to about 0.6 MHz, in the composite color television signal composite system synthesizing the three primary color signal and superimposing the carrier chroma signal to the luminance signal.
CONSTITUTION: The blue signal EB is fed to the matrix A via the LPFFb having the cut off frequency fb with the and green color signal R and G. The output of the matrix A is lack in the high band component EB' of blue EB, then the dark and bright component Br changes with the change in E(y-b) component at low band, but at high band, E(y-b) and E(r-g) components are all 0 and only the dark and bright component Br is changed. Accordingly, even with fine stripes, the change in color is not visible but it is visible as the stripes of darkness and brightness.
