IMAGE CALIBRATION AND CORRECTION
Some applications require very precise color reproduction of the images. In addition,
depending on application, different color standards are applied. When preparing for
correct color reproduction, both the source and the projector must be considered.
The projector offers several ways to calibrate colors, as well as correction of the input
signal.
The source may need correction because it is usually not calibrated from the factory,
which leads to higher or lower signal levels than nominal. In addition, R, G and B may
be slightly different (not balanced), adding a tint to the image. Correcting the input signal
means adjusting the gain (contrast) and offset (brightness) of R, G and B individually.
This is in addition to the normal brightness and contrast controls.
The projector may also need calibration regardless of the source signal, because there
may be slight differences in optical coatings, as well as the spectral distribution of
individual lamps, which can even change over time. Calibrating the projector can be
done in different ways, either by changing the color temperature, by defining the x and
y color coordinates or by R, G and B adjustment.
See the MENU system, ADVANCED sub menu, for details on how to correct and
calibrate.
