Abstract
The endoscopic arrangement (10) is provided with a plurality of image sensors (11), a distal end (10a) and a proximal end (10b). Each of the image sensors is arranged to generate a proper sensor clock, which can be influenced by control electronics at the proximal end of the endoscope arrangement so that such sensor, or a plurality of such sensors, can be operated synchronously with each other or synchronously with a clock set externally. The control electronics is provided with mechanism for detecting the sensor clock and/or the sensor frame rate and/or the sensor image phase and adjusting the detected information to a reference clock.
