■ Maximum frame rate period formula

About the H_Period
For a full image, the H_period values are as follows for each PixelFormat.
Calculate the H_Period using the following formulas when cutting out a portion of the
image using ROI.
■ When [PixelFormat] is Mono8, Mono10p, Mono12p, Mono10, Mono12, BayerRG8,
BayerRG10p, BayerRG12p, BayerRG10, BayerRG12 .
H_Period ＝ 14.02
■
When [PixelFormat] is BGR8/BGR10p.
H_Count = Max(2082, (Width + 8) / 8 + 32 )
H_Period = H_Count / 74.25
■ During continuous operation ([Frame Start] trigger is [Off] or [ExposureMode] is [Off])
• Maximum frame rate of sensor output
SensorFR ＝ 1 / ((Height_s ＋ 36)×Hperiod)
• Maximum frame rate by interface
InterfaceFR ＝ 3000 × 1000000 / (Height_s × Width × Pack value)
For a full image, the PackValue are as follows for each PixelFormat.
About the Height_s
[SP-12401M-USB]
When [VerticalBinning] is [1]. Height_s = Height
When [VerticalBinning] is [2]. Height_s = Height x 2
[SP-12401C-USB] Height_s = 8
• Maximum frame rate
FR_Cont ＝ Min ( ＜ SensorFR ＞ , ＜ InterfaceFR ＞）
• Exposure time possible within frames
MaxOverlapTime_longExp ＝ (1 / FR_Cont) － (14 × H_Period)
• Exposure time outside of frame interval
NonOverlapExposureTime ＝ ExposureTime － MaxOverlapTime_long
However, NonOverlapExposureTime_TrOloff calculation results that are 0 or below will be considered as 0.
For TriggerWidth, the trigger pulse is equivalent to ExposureTime.
• Maximum frame rate
FR_longExp ＝ 1 / { (1 / FR_Cont) ＋ NonOverlapExposureTime }
