Method and apparatus for video signal resolution enhancement |
摘要 |
The resolution of relatively low resolution type information signals is enhanced by inserting black level signals between adjacent picture elements at predetermined positions in each odd horizontal scanning line, and inserting black level signals between adjacent picture elements at different predetermined positions in even horizontal scanning lines. The black level signals are inserted by extinguishing a CRT beam in accordance with phase displaced clock signal trains, preferably phase displaced by 180 DEG .
