About DCMS
3About DCMS
3.1 What is DCMS?
The Barco Display Consistency Management Software (DCMS) is a software tool
to calibrate displays in terms of luminance, gamma and gray tracking*. DCMS is
able to calibrate displays to a predefined set of parameters or match displays to
each other. The software uses a USB color sensor to measure color and
luminance.
The term Display Consistency applies to the consistency of color throughout the
gray scale and the consistency of color and luminance between multipl e displays
of the same or different type.
*
Gray tracking means that the color of every gray level from black to white is
constant, and equal to the white point target. In practice, because of LCD
limitations, this holds for gray levels higher than 20% drive.
3.2 Why using DCMS?
Because of spread in backlight, color filter and liquid crystal properties, all LCDs
have different native white points and gamma. The same user settings will
effectively produce different images, visible when the displays are put next to
each other. Appropriate calibration can solve this by matching the luminances,
gammas and white points.
This calibration requirement is general for all markets that use tiled LCD
displays. More specifically, broadcasters must be able to trust the color they are
seeing, so as good as possible absolute calibration (to an absolute, defined
target) is also necessary. This is a matter of cost – used sensor, bit-depth of
display and electronics, cost of color correction software and cross-talk removal,
spread of color filters etc.
DCMS consists of software and sensor performing the given calibration.

3.3 Key components
3.3.1 Calibration system
Calibration with internal test pattern generation (without disconnecting
the display from its source)
The calibration can be done without disconnecting the display. In this case, a
laptop or desktop PC is needed to run the DCMS software. This laptop/PC needs
to be connected to the RS232 service port of the display. The USB color sensor
should be connected to the l apto p/PC . Th e int ernal tes t pat tern generator of the
display is used to create the colored fields needed for the calibration.

DVI
RS232
Figure 1: External calibration system
Calibration with external computer graphics (by using the input source
as calibration system)
Another way of setting up the calibration system is by using the input source as
calibration system. The computer is connected to the display via RS232 and the
color sensor is connected via USB. In this scenario, the colored test fields are
generated as computer graphics.
For this, the display needs to be connected through DVI and driven at native
resolution at 24 bits per pixel color depth.

About DCMS
IMPORTANT
When calibration is done with external computer graphics, please restore all color settings of
the host’s graphics controller to their default value and disable any host services that may
affect the color of the output picture.
3.3.2 Display
Each pixel of the display has 3 sub-pixels. These sub-pixels each have a color
that corresponds with the three wavelengths for which the human eye is the
most sensitive. These colors are red, green and blue (RGB). Each of these subpixels typically has 256 discrete levels. Colors are reproduced by combinations
of these three primary colors.
Gamma is the perceptual linearity of light. Gamma is expressed by a power
function.
Color temperature (or white point) is the ‘color’ of white. We say that the display
has a warm white point or color temperature if the white of the display is
reddish. The display has a cold or cool white point or color temperature if the
white of the display is bluish. The color temperature or white point is expressed
as coordinates in a color space (for example: xy values in CIE1931xyY space) or
the temperature in degrees Kelvin at which a black body gets this color.
Contradictory, we speak of warm white when the color temperature is low (for
example: 3200K) and cold white when the color temperature is high (for
example: 9300K). Daylight has a color temperature of 6500K.
Gray tracking is keeping the color temperature constant for all gray levels
between black and white.
The brightness (light intensity of full white) is also calibrated as the power
applied to the backlights. If the brightness target is set lower than the dimming
capabilities of the backlight driver then additional dimming can be applied in the
video if the display supports this function.
:
3.3.3 Sensor
The sensor used for calibration is the Barco USB color sensor (not sold
separately). This sensor has a USB interface to the host PC running the DCMS
application. Accuracy of the sensor is < 0.005 xy in CIE1931xyY color space.
Luminance accuracy is < 5%. The sensor is shipped with a suction cap to attach
the sensor to the monitor and a pod for dark current calibration of the sensor.
