Abstract

PURPOSE: To obtain the vertical contour correction signal (V-DTL) containing the signal component equivalent to 2 channels through a simple constitution by forming the signal generator with the delay line and the arithmetic circuit and with 2 signals of the color TV three primary color signals used as the input.
CONSTITUTION: Non-delayed TOP signal 2 among the G signals supplied to terminal 1 plus MAIN signal 4 delayed via 1-line delay line 3 are turned to MG-TG signal 6 through operator 5. While the R signal and signal 4 which are supplied to terminal 7 are turned to MG+R signal 9 through operator 8. Furthermore, signal 9 and BTG+R signal 11 delayed by 1-line delay line 10 of the BOTTOM side are changed into MG+R-BTG+R signal 13 through operator 12. Signal 6 is added to signal 13 at operator 14, and the V-DTL signal containing the 2-channel signal components of MG- TG+MG+R-BTG+R can be obtained through terminal 15. In addition, signal 9 is supplied to horizontal contour correction (H-DTL) signal generator 16 to produce the H-DTL signal.
