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
Register CORE_RATE; 1/2, 1/4, 1/8 and 1/16 for 00, 01, 10 and 11, respectively.
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
Register HUE can be adjusted between -180 degree and +180 degree. The value can be a 2's complement
between -512 and +511. Register SATURATION is applied after adjustment of Register HUE.
