Equipped with the world's first "intelligent lamp control system" based on a
combination of the newly-developed "lamp control" and "color shift correction
technologies".By automatically adjusting the lamp output *

in accordance with
the brightness of the projected image, the newly-developed "lamp control"
technology greatly expands the lamp control (brightness adjustment) range,
while at the same time reducing the power consumption by up to 69% compared
to conventional model*
1
and achieving a high contrast of 2000:1.The "color shift
correction" technology maintains color reproducibility by performing real-time
corrections of color balance (red (R), green (G), blue (B)) shifts which occur at
low lamp outputs resulting from the power consumption reduction.Moreover, in
addition to the "AUTO" adjustment mode, "Normal", "Eco1", and "Eco2" modes are
also available to enable the optimal projection brightness for any occasion.
