The present invention relates to a portable bar code reading device that generates electronic representations of a substrate having a bar code symbol disposed thereon. A portable bar code reading device according to the invention can incorporate a solid state image sensor and can generate first and second electronic representations. The first and second electronic representations generated by a portable bar code reading device in one embodiment represent first and second regions of the substrate that are of different sizes. A portable bar code reading device having a memory and a trigger can be configured to attempt to decode a bar code symbol by processing of an electronic representation and further can be configured so that the first and second electronic representations are stored into the memory after a single depressing of the trigger. A portable bar code reading device can be configured so that the portable bar code reading device completes storing of the second electronic representation into the memory after completing storing of the first electronic representation.
