Abstract
A control unit for generating a timing signal for an imaging unit in an inspection system in which an image of an inspection target object is captured by the imaging unit while the inspection target object is caused to travel in a predetermined direction includes a traveling distance determination section configured to detect a traveling distance of the inspection target object based on a count value acquired as an integer value from a laser interferometer provided in the inspection system for detecting a traveling distance of the inspection target object, and configured to determine whether the detected traveling distance reaches a threshold, and a timing signal generation section configured to generate a timing signal when it is determined that the detected traveling distance reaches the threshold. The traveling distance determination section executes the determination by using a plurality of values selectively as the threshold.
