Abstract
PURPOSE: To ensure expression of the minute detail variation with reduced change of the gradation levels in case the black/white TV signal undergoes the pseudo color display by giving the color display of an optional width at an optional level of the black/white TV signal.
CONSTITUTION: In case the pseudo color display is given to the black/white TV signal, the reference current flowing to resistances 9∼11, variable resistances 18 and 19 plus resistance 17 is made constant via constant current diode 16 connected to power terminal 2. And then voltage VM and VL applied to wind comparators 12∼ 14 are made constant. Variation of voltage VM and VL is secured by resistance 18 and 19, and thus optional level VL is decided by resistance 19. At the same time, optional level width VM-VL is decided by resistance 18. The black/white TV signal is applied to each of comparators 12∼14 from input terminal 1, the output of 12∼14 are applied to color encoder 15, and the color TV signal of an optional width is delivered at an optional level of the black/white TV signal to output terminals 4∼ 5 of encoder 15.
