Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verändern der Leuchtdichte und des Farbortes eines LCD-Displays, welchem Videoausgangssteps einer Look-Up-Tabelle zuführbar sind. Darüber hinaus betrifft die Erfindung eine Schaltungsanordnung zur Durchführung des Verfahrens.The The invention relates to a method for changing the luminance and the color locus of an LCD display, which video output steps a Look-up table feedable are. About that In addition, the invention relates to a circuit arrangement for carrying out the Process.
Insbesondere im medizinischen Bereich sind die Anforderungen an ein Bild wiedergebendes System oder an benachbart angeordnete Bild wiedergebende Systeme im Hinblick auf einen Gesamteindruck der Systeme recht hoch. Beispielsweise ist gewünscht, dass eine Farbe oder ein Grauwert auf benachbarten LCD-Displays einheitlich dargestellt wird. Ohne geeignete Maßnahmen ist eine derartige einheitliche Darstellung nicht möglich, da aufgrund von Fertigungstoleranzen Farb- und Grauwertabweichungen unvermeidbar sind.Especially In the medical field, the requirements for a picture are reproducing System or adjacently arranged image reproducing systems quite high in terms of the overall impression of the systems. For example is desired, that one color or a gray scale on adjacent LCD displays is displayed uniformly. Without suitable measures is such uniform presentation not possible because due to manufacturing tolerances color and gray scale deviations are unavoidable.
Ein LCD-Display wird gewöhnlich in der Art und Weise abgeglichen, dass zunächst mit einer geeigneten Messeinrichtung Farborte und Leuchtdichten des Displays in Abhängigkeit von Videoeingangswerten erfasst werden. Die erfassten Werte werden schließlich mit Sollwerten verglichen, wobei aus den Abweichungen Videoausgangswerte ermittelt und in der Look-Up-Tabelle hinterlegt werden. Ein derartiger Abgleich kann nur durch geschultes Personal erfolgen.One LCD display becomes ordinary adjusted in the way that initially with a suitable measuring device Color locations and luminance of the display as a function of video input values be recorded. The recorded values are finally with Setpoints are compared, wherein from the deviations video output values determined and in the look-up table be deposited. Such a comparison can only by trained Staff.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein vereinfachtes Verfahren zum Verändern des Farbortes und/oder der Leuchtdichte eines LCD-Displays auf gewünschte Werte anzugeben. Darüber hinaus ist eine geeignete Schaltungsanordnung zur Durchführung des Verfahrens anzugeben.Of the present invention is based on the object, a simplified Method for changing the Color location and / or the luminance of an LCD display to desired values specify. About that In addition, a suitable circuit arrangement for carrying out the Specify method.
Diese Aufgabe wird im Hinblick auf das Verfahren durch die im Anspruch 1 angegebenen, im Hinblick auf die Schaltungsanordnung durch die im Anspruch 2 angegebenen Maßnahmen gelöst.These Task is in terms of the method by the in the claim 1 specified, with regard to the circuit arrangement by the specified in claim 2 measures solved.
Vorteilhaft ist, dass auch ungeschultes Personal vor Ort auf einfache Art und Weise das Display im Hinblick auf Farbort und/oder Leuchtdichte einstellen kann. Ein Messgerät vor Ort ist dazu nicht erforderlich.Advantageous is that even untrained staff on site in a simple way and Make the display in terms of color location and / or luminance can adjust. A measuring device on site is not required.
