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.

A scanning method and apparatus. The method comprising the steps of: measuring an ambient video level using an area sensor under the control of a processor means; and calculating a gain and/or a exposure time and/or light source power for an actual flash video level using a stored reference flash video level and the measured ambient video level such that a summation of the actual flash video level and the ambient video level yields a desired video level in a scan image of the document using the calculated gain and/or exposure time and/or light source power.

In an actively illuminated imaging system (240), illumination of a segmented scene (260A-D) is synchronized with an image sensing period. A scene is segmented into a plurality of scene portions (260A-D) utilizing a segmented lens (256). In an aspect, a first scene portion (260A) is illuminated when an imager (254) is actively collecting photogenerated charge from the first scene portion (260A), and a second scene portion (260B) is illuminated when an imager (254) is actively collecting photogenerated charge from the second scene portion (260B). The sensitivity of an image sensor (254) is maximized, while simultaneously minimizing the amount of light that must be supplied to illuminate a scene. An irradiance pattern is varied allowing a more uniform distribution of light. Bands of varying wavelength, polarization, and light intensity may be variously applied to illuminate individual scene segments, as needed to enhance an identification of an object in the scene. The present invention is particularly useful with high frame rate imaging systems.
