ABSTRACT:
A postal materal reading apparatus is provided with a mechanism for obtaining an image signal which represents a visual image of the surface of postal material. A detector is provided responsive to that image signal for identifying an area of that image which contains an edge mark that may interfere with orientation analysis of the image. A detector is also provided responsive to the identification of that area for analyzing the image signal for only that portion of the image signal which represents the image outside the area in which the edge mark was detected, to determine the orientation of the postal material. In the preferred embodiment, a histogram is used to identify the area of the image which contains the potentially interfering edge mark.
