| titleOfInvention | Method and device for automatically checking a video signal |
| abstract | A method for automatically checking the video signal supplied by a monitoring television camera for changes in its picture content is disclosed, in which the digitally processed information of a frame is compared with the corresponding information of a preceding frame, the field of view being divided into a predetermined number of part-fields, the video signal is differentiated, band limited and sampled by an analog/digital converter in each of the part-fields at a predetermined number of points uniformly distributed in the relevant part-field, a first computing unit forms the sum of the amounts of the amplitude values of the points of each part-field in each case arranged in a row, subtracts this sum from a stored row sum, formed in the same manner, of a preceding frame and stores the amount of the difference as measure of row change, and a second computing unit forms the sum of all measures of row changes of the relevant part-field and compares the sum of each part-field in each case with a stored threshold value. |
