Claim:
Method for calibration, controlled by measurement technology, of at least one device unit of a device system ( 1 ), which comprises at least a monitor ( 3 ) for image processing and a standard light device ( 5 ), comprising the method steps: a) first, the monitor is calibrated using a color and light measurement device ( 4 ) as well as an evaluation program stored in the memory of an evaluation unit ( 2 ); b) the luminance is measured, in cd/m 2 , at the calibrated monitor ( 3 ), and this actual value is stored in the memory of the evaluation unit ( 2 ) as a reference value for the calibration of the standard light device ( 5 ); c) using said color and light measurement device ( 4 ), the luminance is then measured at the standard light device ( 5 ), and the actual value is also passed to the evaluation unit ( 2 ), by way of a signal line ( 4 a ); d) in the evaluation unit ( 2 ), the actual value of the luminance at the standard light device ( 5 ) is compared with the value for the luminance of the monitor ( 3 ) stored in the memory of the evaluation unit ( 2 ) as a reference value for the standard light device ( 5 ); e) if there is a difference between the actual value of the measurement at the standard light device ( 5 ) passed to the evaluation unit ( 2 ) and the stored reference value, the standard light device ( 5 ) receives a control signal from the evaluation device ( 2 ), to change the brightness or the contrast; f) this regulation is continued until no difference exists any longer between the measured actual value at the standard light device ( 5 ) and the reference value stored in the memory of the evaluation unit ( 2 ).
