(1092 CLK + 2568 CLK x Shutter Speed) / 72 MHz
<For example, when you set shutter speed in 1/200 s (at
All pixel readout, Partial scan
)>
(1092 CLK + 1920 CLK x Shutter Speed) / 72 MHz = 1/200 s
1092+1920 x Shutter speed = 36x10

/ 200
1920 x Shutter speed = 72x10
6
/ 200 - 1092
∴ ∴ ∴ ∴Shutter speed = (72x10

/ 200 – 1092) / 1920 = 186.931...

when you set shutter speed in 1/200 s, Please send a write command as follows.
(1) to write data 0xBB to address 0x68, to write data 0x00 to address 0x69.
(2) to write data 0x01 to address 0x6E
