Abstract: An endoscope system includes a radiation source which emits a modulated radiation and is applied in a manner such that an object to be examined by an endoscope may be illuminated with the radiation. A sensor is provided for detecting the radiation reflected by the object, at least one picture point. An evaluation device obtains readings of the detected radiation from the sensor, determines phase differences on the basis of these readings, and computes the distance of the object to the sensor device on the basis of these phase differences. A corresponding supplementary module for an endoscope and endoscope optics with these features are also provided.

Abstract: A method for representing a composite image on a screen of a screen device, the image being composed of a plurality of natural and/or synthetic sub-images generated by diferent sources, is characterized in that the sub-images are composed of a line-by-line representation on the screen by (a) reading out at video rate a pluralaity of pixels, the number of which corresponds to that of the respective sub-image from said storages line by line and (b) repeating step (a) line by line. Furthermore, there is set forth a device for carrying out the method according to the invention.
