Color Correction
Color correction (CCR) enables input video color
correction (black balance/white balance adjustment,
gamma correction, knee correction, etc.).
Note
The following optional boards are required to use the color
correction function.
• MKS-2420M Color Corrector Board
• MKS-2440 Frame Memory Board Set
The MKS-2420M is mounted on the MKS-2440.
Selecting the Color Correction
Signal
To apply color correction to a signal, capture the signal
from the CCR1 bus or CCR2 bus.
The following signals can be selected from these buses.
• All primary inputs
• Frame memory video 1 to 3
• Frame memory key 1 to 3
•White
• Black
• Color background
To select a signal
1
Press the [CCR1] or [CCR2] AUX delegation button.
The cross-point button rows are assigned to the CCR1
bus or CCR2 bus.
2
Press a button in a cross-point button row to select the
desired signal.
The button lights in red (high tally) if the signal on the
CCR1 bus or CCR2 bus is included in the program
video (final output video). Otherwise it lights in amber
(low tally).
Output of Color Correction Results
You can assign signals to which color correction has been
applied to cross-point buttons, and output the corrected
signals by pressing those buttons.
For details of the assignment process, see “Selecting
