10.5.5 Smearless mode
This function can be used to reduce the smear coming from bright areas or objects within the
image. This is effective for both EPS and PWC trigger modes. Before the accumulation starts,
any charge that is stored in the pixel is dumped by a high-speed transfer. This can reduce the
smear that is visible directly above a bright object in the image, but the smear showing below
the object is unaffected.
At the falling edge of the trigger pulse the high speed transfer starts. This period is 6.34ms
which is 196L. Thereafter the residual charge in the horizontal CCD register is read out in 1L
and the new exposure starts. This function is available for both full scan and partial scan.
This function can be set if Smearless Enable in JAI Acquisition Control is set at True.
