Fixed time exposure
( syn c=1, exp c=1 ,exp t=N ,exp lt= A)(s ync =3, expc =1, expt =N, expl t=A )
Exposure during the period of the equation below from the timing of leading edge of EXT.SYNC(CC1).
Exposure time
= 66.7 + (N ×256 + A)0. 033
( μse c)
Minimum exposure time
= 66.7 μs ec
* Note that the minimum period of EXT.SYNC is 133.4μsec in
Minimum period=66.7μsec+DATA output duration(66.7μsec)
