[Concept of using Cycle Buffer]
The greatest feature of this function is the imaging of the predetermined number at a constant
time interval unrelated to reading processing time. Set the number of imaging within the
MAXIMG
setting (16 sheets maximum) for the imaging at regular intervals. Otherwise the
imaging interval will vary depending on the reading processing time after the number of
imaging.
Shortening the capture time by reducing the capture resolution (number of pixels) can shorten
the imaging interval.
[Configration Example]
The relation among Shutter Time (SHUTT) , Capture Time (CAPIMG), Imaging
Interval (WAITIMG) and Total Imaging Cycle (CAPCYC) are as follows.
CAPCYC
＝
SHUTT + WAITIMG
Set the Moving Time T = L / V < (16 × CAPCYC)
when the moving object's speed is V and the object's moving distance is L.
Within 16 Images
Moving Speed
Moving Distance L
MAXIMG=16
、
SHUTT=1/1000s=1ms
、
CAPIMG=16ms
、
WAITIMG=10ms
Imaging Cycle is CAPCYC=SHUTT+WAITIMG=1ms+16ms+10ms=27ms.
(1)Moving speed V when the imaging range is L=100mm is:
L/V < 16×CAPCYC
⇒
V > L/(16×CAPCYC) = 100mm/(16×27ms) = 0.231mm/s = 14(m/min.)
∴
V > 14m/min.
(2)Imaging range L when the moving speed is V=30m/min.( = 500mm/s = 0.5mm/ms)is:
L/V < 16(CAPCYC)
⇒
L < 16×CAPCYC×V = 16×27ms×0.5mm/ms = 216mm
∴
L < 216mm
