The present invention relates to a bar code reading device in which there is derived image data in a plurality of different formats. In one embodiment, first and second image data formats can be derived simultaneously from a video signal. Also, both of the first and second image data can be subject to decoding processes. The first image data can be stored in a first memory space and the second image data can be stored in a second memory space. In one embodiment, the first and second memory spaces can each include a two dimensional representation of a substrate on which a bar code symbol is disposed.
