Song Lyrics Contour Processing Device Of Song Accompaniment Device

摘要

In the song accompaniment system of CDG disc, when the lyrics are subtitled with the external video signal as the background, the contour processing is implemented on the subtitle text, so that the clear character representation and the song lyrics contour processing device of the song accompaniment device can be recognized.In the existing song accompaniment system, words are displayed on the background screen through the background screen of external video signals, At this time, when the brightness and color of the external image surrounding the text maintain a similar level incompatible with the brightness and color of the text, it is possible that the background image and the text can not be recognized separately.In this study, we modulate the text color difference signal delayed by the first geo method (6) and the second geo method (7)The composite number end (10) of the character color signal output by the modulation tool (8) and the text brightness signal output by the third delay means (9),In the text brightness / collar signal output from the synthetic water end (10) and the contour processing tool (13), the output switching means (12) andFor the external video signal of the background, a contour line with a certain thickness is formed in the text outline with the text brightness signal (y) as the center, which is used as the contour processing device of the song lyrics of the song accompaniment device composed of the output contour processing tool (13),Through the outline of the words expressing the lyrics, the background picture and the words are easier to recognize.
