DEFINITION

Classification: 235/462.41

Using an imager (e.g., CCD):

(under subclass 462.01) Subject matter wherein an image of the bar code is focused onto an image sensor such as a charge coupled device.

(1) Note. A charge coupled device (CCD) is a semiconductor storage device in which an electrical charge is moved across the surface of a semiconductor by electrical control signals.

(2) Note. The sensor normally has a set of discrete photosensitive cells or pixels.
