CXD3009Q
(a) Auto Focus ($47)
Focus search-up is performed, FOK and FZC are checked, and the focus servo is turned on.
If $47 is received from the CPU, the focus servo is turned on according to Fig. 4-3. The auto focus starts
with focus search-up, and the pickup should be lowered beforehand (focus search-down). In addition, blind
E of register 5 is used to eliminate FZC chattering. In other words, the focus servo is turned on at the falling
edge of FZC after FZC has been continuously high for a longer time than E.
