Calibration
In many cases, calibration is the remedy for a display
that is no longer conform to its Preset.
The calibration routine restores the black luminance, the
white luminance and the display function.
Display Function
A Display Function describes how a display device
converts the voltages at the inputs into light.
In the context of a medical viewing station, a display
device is the combination of imaging board (display
controller) and display.
The display function is a graph that shows how the light
from the display panel evolves from minimum to
maximum luminance while the data levels at the input of
the display controller go from 0 to maximum.
Display Controller head
An imaging board or graphics board converts the digital
data from the computer into digital or analog video
voltages.
Most of the common imaging boards contain just one set
of video and sync outputs. However, some high-end
boards, like some of the BarcoMed boards, contain two
sets of video and sync outputs. This is called a dual head
imaging board. It is like two complete imaging boards
implemented on one single unit.
A dual head board in the computer behaves exactly as if
two separate boards were installed.
