Abstract: A more effective larynx or vocal fold examination is facilitated when an image recording device, preferably a color image recording device comprising three modes is made available, a face-recording recording mode with a low recording frequency or image repetition frequency, respectively, but with a high resolution, a further face-recording recording mode with a higher image repetition frequency but with a lower resolution, and a one-dimensional, for example, row-recording mode also having a higher image repetition frequency. By the switchability of the image recording device between those modes the examining doctor is capable of first getting an overview by means of the slower image recording mode, wherein this may also be done in color, as due to the slower recording frequency this mode is not subject to the illumination problems like the high-speed camera.
