About
Smear Reduc tion Processing (SRP) is a custom -designed tem poral blanking solution used to reduce o r elim inate sm earing in high
motion im agery. Available settings are either SRP Half, S RP F ull or Off.
Both settings introduce 8.3333 ms Dark Time to the image @ 60 H z or 4.1666 ms @ 120Hz, however the color wheel sequencing
differs between the two mo des of operation to give a different visual e ffect. R espective c olor wheel sequenc es are RG B, blank for
SRP™ Half a nd RGB, RGB blank / blank for SRP ™ Full. R esults are subjective and therefore the mode se lected is entirely at the
discretion of the end user.
Increasing D ark Time has an adverse effect o n projector brightness. For example increasing Dark Time by 8.3333 ms represents
exactly half of the 16.6666 ms video frame interval at 60Hz , brightness subsequently reduced by 5
0% as a result. It is important to
note that full color bit depth is retained even when brightness is reduced. In order to recover s ome brightness color wheel spokes
are enabled by default when S R P™ Half and F ull settings are applied. This default setting can be ov erridden by enabling SRP at
Main menu — S ettings — Service — Enable advance d profiles if required.
Using SRP™ with the projector in AS3D mode is not supported.
Mode selection is from the O S D Main m enu — Picture — RealColor — BrilliantColor menu or via external control.
