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.

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.
