E. GAMMA BLOCK
If ISP input image is too dark, INPUT GAMMA exists for compensation.
In order to compensate the GAMMA characteristics of the display device, OUTPUT GAMMA exists.
Simple compensation of INPUT GAMMA is achieved through GAIN CONTROL.
Compensation is achieved in a way that directly controls the conversion function with a 16-point
OUTPUT GAMMA.
F. APERTURE BLOCK
This block strengthens the composition of the image by increasing the image resolution.
In order to prevent noise increase in low light, the differential of APERTURE GAIN shall be applied
accordingly. THRESHOLD interval is divided according to the Y-level, GAIN settings may be different
from one another.
Adaptive Directional Filter improves vertical, horizontal edge components.
G. HUE CONTROL BLOCK
As the R-Y, B-Y signals, output from CCD do not have ideal spectral characteristics, HUE CONTROL
BLOCK provides Error Controls.
Chrominance signal GAIN and HUE can be adjusted.
GAIN, HUE configuration can be controlled in all 8 directions. Also, control area is divided into 4 sections
of chrominance signals in order to control only certain areas of the chrominance signal.
8-way GAIN / 8-way HUE / 4 Area Control.
