ABSTRACT:
A video inspection device using a field mode CCD camera. In order to inspect the printing on a moving web, a field mode CCD camera is provided with a zoom lens and strobe light. The image obtained is processed so that only alternate pixels of the image are stored. When reading out the stored image, the image is blown up by a factor of two and the missing pixels are interpolated horizontally and vertically. The resultant image is displayed in a monitor for the operator to inspect.
