Abstract
Apparatus for determining at least one edge of an object having a plurality of openings with respective edges. An imaging device generates an image signal of the object to represent light intensity values of a plurality of pixels, the image signal being processed to estimate a linear relationship derived from the light intensity values of a predetermined number of the pixels. A determining device determines whether the linear relationship includes at least one light intensity value corresponding to an edge.
