Typical value
*
2
Calculated from the ratio of the full well capacity and the readout noise.
•
The frame rates in the table above are the output frame rates from the camera.
•
Since the frame rates of image acquisition by software depend on the PC performance and
the application software, they may be slower than the frame rates in the table above without
sufficient PC performance and application software. The slower frame rates mean the lost
frames.
•
The lost frames will be reduced by using Frame bundle function of DCAM-API software that
transfers multiple frames at once.
