Notes:
1.
In Interlaced Mode, there are even/odd field different (t8). When In Progressive Scan Mode, only frame timing same as Even
field(t8).
After VSYNC falling edge, OV6630 will output black reference level, the line number is T
VS
, which is the line number be-
tween the 1st HREF rising edge after VSYNC falling edge and 1st valid data CHSYNC rising edge. Then valid data, then
black reference, line number is T
VE
, which is the line number between last valid data CHSYNC rising edge and 1st CHSYNC
rising edge after VSYNC rising edge. The black reference output line number is dependent on vertical window setting.
When in default setting, T
VE
