摘要： A pixel array system for high accuracy detection of displacement, speed and acceleration includes: an array comprising m columns and n rows, wherein at least every other row is offset with respect to a preceding row of the array. In a first embodiment, every other row is offset with respect to a preceding row of the array by 25% of a pixel width. In a second embodiment, every two rows are offset with respect to a preceding two rows of the array by 25% of a pixel width.

摘要： A media tracking sensor (MTS) apparatus for performing a calibration procedure to determine a resolution calibration factor includes: a full sensor array including: a first virtual array, having a first width, for capturing a calibration reference image; and a second virtual array having a third width equal to the first width, for capturing a plurality of images and comparing the captured images with the calibration reference image. The MTS apparatus further includes a print media positioned below the full sensor array; and a host system for moving the print media below the full sensor array. When the first virtual array captures the calibration reference image, motion data of the full sensor array will be set to zero, and when an image captured by the second virtual array matches the calibration reference image, total motion data will be recorded and used to determine the resolution conversion factor.
