ENDOSKOP MIT FARBTREUER BILDDARSTELLUNG

摘要

In order to achieve faithfully coloured endoscopy images, in particular during medical examinations, colour references (4) provided on the endoscope tip are also co-recorded essentially at the same time as the surface region (1) to be examined. Computational comparison of the colour of these references (4) with colour values which the references exhibit under controlled illumination conditions is used to calculate that colour space transformation matrix by means of which the measured ACTUAL colour values can be recalculated into the DESIRED colour values. In this way, the pixels of the image sections of interest are retransformed before representation on a colour monitor (11) using this transformation prescription. If required, the retransformed pixels can be divided into previously determined, e.g. previously learned, colour classes and represented as a colour class image in order to facilitate the diagnosis.
