Abstract

Bei einem Verfahren zum Erfassen und/oder Auswerten von Bewegungsabläufen unter Verwendung eines digital aufzeichnenden optischen Aufnahmegeräts werden Eigenschaften eines oder mehrerer Bildpunkte (Pixel) der digitalen Kamera, wie z.B. die Koordinaten in der Bildebene, die Farbe, die Intensität und/oder der Kontrast benachbarter Bildpunkte zur Erfassung und/oder Auswertung herangezogen, wobei die Koordinaten von Bildpunkten in Zeitintervallen miteinander verglichen werden und bei einer Abweichung von einem Vorgabewert als Ereignis und/oder bei einer nachfolgenden unveränderten Position des oder der Bildpunkte als Ereignisdauer gezählt und/oder ausgewertet werden.In a method of acquiring and / or evaluating motion sequences using a digitally recording optical pickup device, characteristics of one or more pixels of the digital camera, e.g. the coordinates in the image plane, the color, the intensity and / or the contrast of adjacent pixels used for detection and / or evaluation, wherein the coordinates of pixels in time intervals are compared with each other and a deviation from a default value as an event and / or at a following unchanged position of the pixel or pixels counted as event duration and / or evaluated.
