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, Mono10Packed, Mono12Packed, Mono10 or Mono12.
GIGE_H_Count_Max = ( Width / 2 + 32 )
Sensor_H_Count: 1041
■
When [PixelFormat] is BayerRG8, BayerRG10Packed, BayerRG12Packed, BayerRG10
or BayerRG12.
GIGE_H_Count_Max = ( (Width + 8) / 2 + 32 )
Sensor_H_Count: 1041
■
When [PixelFormat] is RGB8, RGB10V1Packed or RGB10p32.
GIGE_H_Count_Max = ( (Width + 8) / 2 + 32 )
Sensor_H_Count: 2082
H_Count = Max(Sensor_H_Count, GIGE_H_Count_Max)
H_Period = H_Count / PixelClock
PixelClock: 74.25 (MHz)
■ 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 = 920 × 1000000 / (Height_s × Width × Pack value)
Height_s : [SP-12401M-PGE]
When [VerticalBinning] is [1]. Height_s = Heigh
When [VerticalBinning] is [2]. Height_s = Height x 2
[SP-12401C-PGE]
Height_s = 8
For a full image, the PackValue are as follows for each PixelFormat.
• 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}
