Abstract

The control process involves passing sheets of paper bearing images (1) in front of a camera (2) which inspects them and passes the captured image to a unit (3) which is capable of measuring the misalignment. The measured value of misalignment is sent to a memory (4). The memory (4) contains all the pixel models which have acceptable misalignment and the model matching the measured value most closely is chosen and transmitted to comparator (5). The comparator compares subsequent images captured by the camera with the selected pixel model thus establishing automatic image control.
