Title:
METHOD AND DEVICE FOR THE STROBOSCOPIC RECORDING AND REPRODUCTION OF REPETITIVE PROCESSES
Document Type and Number:
WIPO Patent Application WO2001064096
Kind Code:
A3
Abstract:
The invention relates to a method and to a device for the stroboscopic recording and reproduction of images of a repetitive process (12), especially of moving vocal chords (larynx diagnostics). The aim of the invention is to improve image quality, especially the brightness and definition of the images while requiring little lighting equipment. According to the inventive method, the process (12) to be observed is illuminated with a steady light source (14). Trigger pulses STrigger are generated to trigger exposures to record the image information of the process (12) by an image sensor (16). The image information from a plurality of subsequent exposures is added in a background memory of the image sensor (16) to produce image information sums. The image information sums thus obtained are stored in the background memory (18) of the image sensor (16) and the background memory (18) is read and deleted, and the image information sums are processed to give a video signal.
