Maximum Line Rate Calculations
The maximum line rate in the camera is limited by either the Camera Link row time or the sensor row
line time. The following calculations are used to determine the maximum line rate.
Variables for calculations:
•
User.SOT = 80 | 160 | 320 | 640
•
User.CLM = 2(3) | 15(16) | 21
•
User.SBH = 1 | 2 | 4
•
User.SDH = 1 | 2 | 4
•
User.SBV = 1 | 2 | 4
•
User.SDV = 1 | 2 | 4
•
User.TDI = 0 | 1
•
User.STG = 16 | 64 | 128 | 192 | 240 | 256
CL_Taps
•
If User.CLM = 2(3) then CL_Taps = 2
•
If User.CLM = 15(16) then CL_Taps = 4
•
If User.CLM = 21 then CL_Taps = 8
Hor_Bin = User.SBH * User.SDH
CL_Row_Time = ( ( 8192 / Hor_Bin / CL_Taps ) + 8 ) / ( ( User.SOT / CL_Taps ) * 1e6 )
HN_Row_Time = ( 3 + ( ( 36 * User.SBV ) + 545 ) ) / 20e6
HN_Adjust
•
If HN_Row_Time > CL_Row_Time then HN_Adjust = 0
•
Else HN_Adjust = Ceiling ( ( CL_Row_Time - HN_Row_Time ) * 20e6 )
HN_Rows
•
If User.TDI = 1 then HN_Rows = User.SDV
•
If User.TDI = 0 then HN_Rows = ( ( User.STG / User.SBV ) + 7 )
HN_Time = ( 3 + ( ( ( 36 * User.SBV ) + 545 + HN_Adjust ) * HN_Rows ) ) / 20e6
Max_Line_Rate = 1 / HN_Time
