Color temperature
The position along the black body curve on the chromaticity diagram, normally quoted in Kelvin. It takes into account the preset values for
color balance in the service set-up to take up the variations in the prism. The projector allows you to adjust this temperature (i.e. adjust the
picture color temperature).
Component video
A three or four wire video interface that carries the signal split into its basic
RGB
components or
luminance
(
brightness
) and two-
color-
difference
signals (
YUV
) and
synchronization
signals.
Composite video
A signal line that carries
luminance
,
chrominance
,
synchronization
pulses and
blanking
.
Contrast (electronic control)
The adjustment of the white point of the image without affecting the black point. This increases the intensity range of the displayed image.
Contrast (optical)
The intensity difference between the darkest and lightest areas of the screen.
Cr, Cb
Color difference
signals used with ‘
Y’
for digital
Component Video
inputs. They provide information about the signal color. Not to be
confused with
Pr, Pb
.
Crop
Remove part of the projected image.
Alternatively, fit an image into a frame with a different
aspect ratio
by removing part of the image. The image is resized so that either its
length or its width equals the length or width of the frame, while the other dimension has moved outside the frame; the excess area is then cut
out.
