• The shaded parts of the tables are items that you set or input yourself.
• 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 = Tv – Tb
where Tb: BLKG interval [line]
Tw: External VD width [line]
Tv: VD interval [line]
Note that there is no difference in the number of effective lines between
Bining ON and Bining OFF.

* 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)
