Abstract
A method for calibration is controlled using measurement technology of at least one device unit of a device system which includes a monitor for image processing and a standard light device. The monitor is calibrated, and the luminance is measured at the calibrated monitor and at a standard light device. The actual value of the luminance at the standard light device is compared with the value for the luminance of the monitor. If there is a difference, the standard light device receives a control signal to change the brightness or the contrast. This regulation is continued until no difference exists between the measured actual value at the standard light device and the reference value stored in the memory of the evaluation unit.
