Clamp operation can be set to a mode where only the post-stage brightness clamp does not operate even if
a clamp pulse is input to the CLPIN (Pin 113). At this time, all three channels of the CLP pins
high impedance simultaneously, and the signal black level can be varied in an analog manner by setting the
voltages externally. However, the voltage value set here is not related to the VRT (Pin 17) and VRB (Pin
93) voltages or the OUT
monitoring the ADC data output or the data after that.
The two monitor signal outputs ( OUT pins
amplifier output signal immediately before input to the ADC, and other is after switching between the two
lines of select switch.
The RGB channel gains can be set collectively by an 8-bit DAC setting.
The Rch contrast (R amplifier gain) can be adjusted independently within the range of ±21% relative to the
main contrast by an 8-bit DAC setting.
The Gch contrast (G amplifier gain) can be adjusted independently within the range of ±21% relative to the
main contrast by an 8-bit DAC setting.
The Bch contrast (B amplifier gain) can be adjusted independently within the range of ±21% relative to the
main contrast by an 8-bit DAC setting.
