90 StudioPix™ Pixelation Luminaire User Manual
The following adjustments affect the boundaries between elements of an image. They
are especially useful for adjusting the borders of a figure moving against a
background.
Luminance /Distance Weight
The final LED colors in echo are calculated by a weighted average of the pixels surrounding the
LED area. Increasing the Luminance Weight, means that brighter pixels will contribute more to
the final LED color than darker pixels. Likewise, as Distance Weight is increased, pixels that are
closer to the center of the LED will contribute more than pixels that are further away.
Luminance Cutoff
Specifies the minimum brightness of a pixel for it to be taken into account when calculating the
final LED color. This allows you, for example, to keep bright or dark parts of an image from
effecting the LED color.
Cutoff Mode/Luminance
These controls effect how the Luminance Cutoff works. When the Cutoff Mode is set to Less,
then pixels that are darker than the specified Luminance Cutoff are ignored.
When the Cutoff Mode is Greater, then pixels that are brighter than the Luminance Cutoff are
ignored. The Luminance Invert control is used to invert the luminance value before it is tested
by the cutoff (it does not invert the final color).
