Patent ID: 7102554

Claim:
A method for setting an A/D converter which can be fed an analog image signal from which the A/D converter generates a digitized image signal, wherein an offset point of the A/D converter can be set in such a way that the A/D converter generates a minimum video step of the digitized image signal from a minimum video level of the analog image signal, wherein an amplification of the A/D converter can be set in such a way that the A/D converter generates a maximum video step of the digitized image signal from a maximum video level of the analog image signal, wherein a look-up table evaluates the digitized image signal and transmits output values assigned to the video steps to a panel via an interface, causing image information to be visually displayed, the method comprising: setting the offset point of the A/D converter by loading the look-up table with values which produce a first item of image information if the offset point is correctly set and which produce a second item of image information different from the first item if the offset point is incorrectly set; feeding the A/D converter an analog image signal with predefinable video levels whose digitized values correspond to the first item of image information if the offset point of the A/D converter is correctly set; and adjusting the offset point until the first item of image information is displayed.
