* Because the CCD has 494 vertical effective pixels, 11 lines of invalid
pixels are output at the end of the image when high-rate scan is OFF.
(VD interval 525 - effective pixels 494 - BLKG segment 20 = 11 invalid
pixels)

• The shaded parts of the tables are items that you set or input yourself.
• The table is an example in external trigger shutter mode 1 where the
trigger pulse width is 100 µs, and the time from the trigger rising edge to
external VD falling edge is about 1 H (31.78 µs). In this case, about 3
lines at the end of the effective image segment are affected by trigger
input.
• The number of effective lines with high-rate scan set to ON is determined
by the formula shown below.
Under the condition that Tb = 20 when Tw 9, and
Tb = Tw + 11 when Tw > 9,
X = T – Tb – 2
where Tw: External VD width [line]
Tb: BLKG interval [line]
T: Trigger interval [line]
2: Ineffective interval [H] caused by trigger input
Note that there is no difference in the number of effective lines between
Binning ON and Binning OFF.
