Abstract: Various embodiments are directed to apparatuses for inspecting an on-line product web moving relative to the apparatus in a machine direction. The apparatuses may comprise a line-scan camera defining a field of view and positioned such that the field of view includes a portion of the product web. A camera control system may be in electronic communication with the camera and may be configured to receive from the web velocity sensor web velocity data indicating a velocity of the product web and convert the web velocity data to a line trigger signal. The line trigger signal may indicate a temporal frequency of camera image captures necessary to achieve a constant machine direction pixel resolution. Additionally, the camera control system may be configured to receive product position data and generate a frame trigger signal considering the product position data. The frame trigger signal may indicate a break between image frames.
