  • Character and pattern mixing apparatus for use in a video equipment
    Patent number: 5499054
    Abstract: A video mixing apparatus for use in a video equipment capable of providing a mixed image luminance signal comprises a synchronization ("sync") separator for providing a horizontal sync, vertical sync and composite sync signals from an input image luminance signal; a character/pattern controller, in response to the horizontal and vertical sync signals, for generating a character luminance and a pattern luminance signals; a character mixer for mixing the composite sync signal with the character luminance signal to produce a mixed character signal; a pattern mixer for mixing the composite sync signal with the pattern luminance signal to produce a mixed pattern signal; and switching apparatus for mixing the mixed character signal and the mixed pattern signal with the image luminance signal to thereby provide the mixed image luminance signal.
