10-9 HIGH FULL WELL CAPACITY MODE
The High Full Well Capacity Mode can increase a full well capacity from 1000 electrons to 38 000
electrons and enable 16 bit digital output.
•
Switching Standard Full Well Capacity mode / High Full Well Capacity mode is done by
HighDynamicRange Mode Off/On in DCAM property.
10-10 REFERENCE: FRAME RATE CALCULATION METHOD
The following is a calculation formula and an example for calculating the frame rate value.
Camera operation modes
Calculating formula
Free running mode
Exp > Vn/4+2
1 / ( ( E x p + 2 ) x 4 H )
Exp
≤
Vn/4+2
1 / ( ( V n / 4 +4 ) x 4 H )
External trigger mode
Edge trigger mode
1 / ( ( E x p + Vn / 4 +6 ) x 4 H )
Level trigger mode
Synchronous readout trigger mode
1 / ( ( E x p + Vn / 4 +3 ) x 4 H )
Global reset Edge trigger mode
1 / ( ( E x p + Vn / 4 +7 ) x 4 H )
Global reset Level trigger mode
Lightsheet Readout Mode
1 / ( ( E x p + Vn / 4 +6 ) x 4 H )
Start trigger mode
Same as the Free running mode
Hn : Number of horizontal pixel (128 to 4608, multiples of 128)
Vn : Number of vertical line (4 to 2592, multiples of 4)
4H : [Standard Full Well Capacity mode]
MAX(Hn / 365.25, 6.304) [µs]
[High Full Well Capacity mode]
50.432 [µs]
MAX(A,B) = the larger value in A and B
In Lightsheet Readout Mode, it can changed up to maximum 200 µs
Exp : roundup(Exposure time setting / 4H) [µs]
roundup( ) = round up to integer
