Abstract
A bar code reader particularly useful in a photographic film scanner of the type employing a light source and CCD array for sensing the bar code elements. Lateral location of the bar code pattern is established by analyzing the output of the CCD array within a bar code detection window to determine the location of a longitudinal edge transition of the line of clock elements in the bar code pattern and then to use clock and data element detection windows at spaced locations from the line of clock edge transition to read the encoded values of the bar code. In one embodiment, the line of transition between the clock and data elements is used as the line of longitudinal edge transition of the line of clock elements. In another embodiment, the longitudinal clock edge transition remote from the data elements and adjacent the central image frame region is used.
