4.1 Vertical Enhancer Function
By setting the VH pin (toggle SW2) to the L level, the vertical enhancer feature is enabled. The coring
parameter of the vertical enhancer can be set up every 1 LSB by the digital code that are input to
C0 – C3 (black level parameter), C4 – C7 (white level parameter), and D4 – D7 (noise slice level param-
eter.
The set up level of the coring parameter and characteristics are as follows.
