A plurality of linear sensors sense a beam spot and the results of sensing the beam spot are corrected. The electronic image pickup apparatus is thereby achieved as having a well-balanced configuration where the body is neither increased in thickness nor too long in a lateral dimension. The ETL extension plan includes one or more ETL plan elements that indicate extensions on ETL metadata objects. When a person is captured in the image, the method includes identifying a human head in the image and assigning the human head a head location in the coordinate space. The fasteners include mounting holes on the margin of the tag body or on the elongated attachment band. The injecting method consists in adding to the ATM cell a switch routing label and a protocol engine correlator by the control point of the injection switching node before injecting the cell into the connection.
