Abstract:
An apparatus for scanning a bar code label, comprising:at least one CCD camera configured to provide a linear array of scan output corresponding to a particular region currently being scanned;a memory for storing the linear array of scan output from the at least one CCD camera;a controller connected to the at least one CCD camera and configured to output the linear array of scan output to a particular region of the memory;a signal processor connected to the memory and configured to output data from particular memory locations of the memory so as to create at least one virtual scan line; anda decoder configured to determine if data corresponding to the virtual scan line corresponds to a real bar code,wherein the virtual scan lines correspond to two 45 degree lines that intersect with each other so as to form an X-shape scan pattern, as well as a horizontal line that provides redundancy data for the decoder.
