f Pressing the <聚焦> button on the remote control for at least three seconds will also display the confirmation screen for lens calibration
execution.
[ACTIVE FOCUS OPTIMIZER]
Enable/disable the active focus optimizer function.
By enabling this function, the shift in focus caused by the temperature change of the projection lens or the change
in brightness of the image, which occurs after the projector is turned on and the projection is started, can be
reduced. It will also reduce the shift in focus right before enabling the shutter function (shutter: closed) and right
after disabling the shutter function (shutter: opened).

Note
f When [ACTIVE FOCUS] is set to [ON], the focus adjustment (adjustment of the projection lens focus position) is automatically performed
by one of or both of the following correction methods. Correction method that will be performed and the factory default setting of [ACTIVE
FOCUS] differ based on the type of the projection lens displayed in the [PROJECTOR SETUP] menu → [LENS] → [LENS TYPE].
Information about [LENS TYPE] is automatically acquired after the projection lens is attached.
Temperature detection correction: Automatically adjusts the focus based on the temperature change of the projection lens.
Brightness detection correction: Automatically adjusts the focus based on the change in brightness of the image.
f Temperature detection correction adjusts the focus by detecting the temperature change of the projection lens for a specific time from each
of the following points.
g When pressing the power on <b> button while the projector is in the standby mode
g When pressing the <快门> button on the remote control or the control panel to disable the shutter function (shutter: opened)
g When switching the setting in the [DISPLAY OPTION] menu → [SHUTTER SETTING] → [STARTUP] from [CLOSE] to [OPEN]
g When the light source is turned off by the no signal lights-out function, and then the light source is turned on again
f Some projection lenses that have the periphery focus adjustment function also automatically adjust the focus balance in the center and
periphery of the projected image.
f Note following especially when constructing multi-display using multiple projectors such as using the edge blending function by setting the
[ADVANCED MENU] menu → [EDGE BLENDING].
g Position of the projected image may slightly shift due to the amount of focus adjustment.
g The projected image may slightly undulate during the focus adjustment.
f When [ACTIVE FOCUS] is set to [ON], driving sound of the focus adjustment motor may be audible at the time of automatic adjustment.
f Even when the [PROJECTOR SETUP] menu → [LENS] → [ACTIVE FOCUS OPTIMIZER] → [ACTIVE FOCUS] is set to [ON], the active
focus optimizer function will not operate if [---] is displayed in the [PROJECTOR SETUP] menu → [LENS] → [LENS TYPE].
f The operation of the temperature detection correction of the active focus optimizer function will stop in the following cases even if [ACTIVE
FOCUS] is set to [ON].
g When focus adjustment, periphery focus adjustment , zoom adjustment, and lens calibration is executed
g When the lens position is loaded
g When pressing the <快门> button on the remote control or the control panel to enable the shutter function (shutter: closed)
g When switching the setting in the [DISPLAY OPTION] menu → [SHUTTER SETTING] → [STARTUP] from [OPEN] to [CLOSE]
g When the light source is turned off by the no signal lights-out function
g When the lens temperature sensor error is detected
f When the [DISPLAY OPTION] menu → [SHUTTER SETTING] → [STARTUP] is set to [CLOSE], the temperature detection correction of the
active focus optimizer function will not operate when the projector is turned on next time, even if [ACTIVE FOCUS] is set to [ON].
f The active focus optimizer function operates within the range of focus adjustment. It may not operate properly when used close to the limit
value for the focus adjustment.
f Execute [LENS CALIBRATION] when the projection lens is replaced.
The active focus optimizer function will not operate correctly if [LENS CALIBRATION] is not executed.
