Abstract
A method of taking pictures of a quick-moving object by means of a video apparatus, whereby the quick-moving object, e.g. a paper web, is exposed to a short light impulse and a light impulse reflected from the object is used to produce an image on an image sensor of semiconductor type in the camera. The light impulse brings dot detectors of the image sensor into a detection state corresponding to the light intensity of each dot, where they remain after the end of the light impulse, whereby the image remains in the storage of the image sensor and can in a normal way by read and recorded on a video tape in the video tape recorder.
