Nowhere else is precise image representation as essential as in the medical environment, for example in radiology or surgery. To guarantee a constant image display, it needs to be calibrated property.
Calibration is the adjustment of two values to a defined value. Important parameters to be calibrated are brightness, gamma, colour temperature and colour space. These must correspond to a fixed value and be kept constant. The brightness is measured for white and is called Lmax. Integrated ALS (Automatic-Luminance-Stabilization) ensures that brightness settings remain stable. Another parameter is the display gamma. This measures the relationship of input signal to brightness. Gamma is the brightness correction for the grey values of the monitor, i.e. the steps between black and white.
