DIGITAL TITLER FOR VIDEO CAMERA

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital title apparatus of a video camera. In order to synthesize a title, such as a character, in a conventional video signal, a character is generated in a character generator and synthesized with a video signal in a synthesizer. In the present invention, the luminance signal Ye (Yg) (Yb) and the color signal (Tr) (Tb) (Tg) are not generated and input to the title signal generator (2). The digital signal Ya / d at once and use the simple analog switches SW1 to SW5 and the negative gates G1 and G2 to directly control the luminance signal Ty 'and the color difference signal Tr-y' for the title. By creating (Tb-y ') and combining it with the original signal (Y) and the color difference signal (RY) (BY), it can be used more widely when inserting a title on any screen, and smoothly adjust the color of the title. So that we can Invention.
