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.
