Abstract
According to an example, an apparatus for controlling a media scan operation may include a first scan module to scan a section of a media, a tracking mechanism to track the media as the media is moved past the first scan module, and a controller. The controller may receive signals corresponding to the media movement from the tracking mechanism, determine, based upon the received signals, a current position of the media, and vary a timing at which the first scan module collects a scan of the section of the media based upon the determined current position of the media.
Claims15
An apparatus comprising:
- a first scan module to scan a section of a media;
- a tracking mechanism to track the media as the media is moved past the first scan module;
- a controller to:
- receive signals corresponding to the media movement from the tracking mechanism;
- determine, based upon the received signals, a current position of the media;
- and
- vary a timing at which the first scan module collects a scan of the section of the media based upon the determined current position of the media.
A method comprising:
- receiving, in a controller, signals corresponding to a movement of media from a tracking mechanism that directly tracks movement of the media;
- determining, by the controller, based upon the received signals, a current position of the media;
- determining, by the controller, whether the determined current position of the media matches a predefined position;
- and
- in response to a determination that the determined current position of the media does not match the predefined position, varying, by the controller, a timing at which a scan bar collects a scan of a section of the media.
A system comprising:
- a controller;
- a plurality of scan modules to concurrently scan different sections of the media;
- a tracking mechanism to track the media as the media is moved past the plurality of scan modules, wherein the tracking mechanism is to directly track movement of the media;
- wherein the controller is to receive signals corresponding to the media movement from the tracking mechanism, determine, based upon the received signals, a current position of the media, and in response to a determination that the determined current position of the media is behind a predefined position, delay collection of scans of sections of the media by the plurality of scan modules.
