10-5 READOUT TIME OF HORIZONTAL LINE
Readout time of the horizontal line is varied depending on the horizontal pixel number set in the
Sub-array readout mode.
Readout time = (Vn+2) × 4H
Vn = number of vertical lines
4H = readout time of one line
The readout time per one line (4H) can be calculated by the following formula:
(1) In Normal Area Mode
Standard Full Well
Capacity mode
4H = MAX
（
Number of horizontal pixel / 365.25, 6.304
）
[µs]
High Full Well
Capacity mode
4H = 50.432
[µs]
(2) In Light Sheet Readout Mode
The readout time in the lightsheet mode is adjustable from the calculated value in the normal area
mode as the minimum value upto 200 µs.
10-6 EXPOSURE TIME SETTING
The exposure time setting can be done by the units of seconds.
The actual exposure time setting is defined by the following formula, and the camera automatically
calculates a longer and closest value from the specified exposure time setting.
(1) In Normal Area Mode
4H × roundup (Exp1 / 4H)
Exp1 = 4H to 1 s (input in units of seconds)
roundup () = round up to integer
(2) In Light Sheet Readout Mode
4H × roundup (Exp1 / 4H)
Vn = number of vertical line
Exp1 = 4H to Vn / 4 × 4H (input in units of seconds)
roundup () = round up to integer
