Figure 10. Sharpness I/O Characteristic Curve

The Sharpness block applies "0" for any value smaller than two times of Register CORE_L shown in Figure 10,

applies a certain gradient for the value smaller than two times of Register CORE_H, and bypasses edge value for

the area bigger than two times of Register Core_H. Any value which is bigger than Register EDGE_LIM is limited

to Register EDGE_LIM. The gradient between Register CORE_L and Register CORE_H is determined by

BLACK/BRIGHTNESS/CONTRAST can be adjusted as following, after EDGE is reflected.

YOUT = (YIN – YCP_BLACK) * YCP_CONTRAST + YCP_BRIGHTNESS

Where, Register YCP_BRIGHTNESS is a 2's complement, and can be a negative number.

5.4.2 HUE & SAT

between -512 and +511. Register SATURATION is applied after adjustment of Register HUE.
