Patent Images

1. An imaging apparatus comprising:

  • an imaging assembly having an image sensor array and a lens assembly for focusing an image onto the image sensor array, the image sensor array comprising pixels arranged in a plurality of rows and columns of pixels, the imaging assembly defining a field of view;

    an illumination assembly for projecting an illumination pattern during an illumination period, wherein at least a portion of the illumination pattern is projected in an area within the field of view;

    wherein a plurality of pixels of the image sensor array, the plurality of pixels comprising a certain row, are exposed during a frame exposure period in which each row of the plurality of pixels has a common row exposure initiation time and a different, sequential exposure termination time;

    wherein the imaging apparatus is operative to process for attempting to decode decodable indicia image data representative of light incident on the image sensor array during the frame exposure period; and

    wherein the illumination period and the frame exposure period are coordinated so that at least a portion of the illumination period occurs during the frame exposure period and further so that the illumination period ends at a time in common with or earlier than an exposure termination time of the certain row.
