ABSTRACT:
In an encoded symbol reader for decoding a two-dimensional encoded symbol having a matrix of cells, an image of the encoded symbol is formed on a CCD, and image data is generated. The encoded symbol reader has a plurality of operational modes, including an image inverse mode. The image data is stored in a memory. When the image data is read out of memory in order to decode the symbol, depending on whether or not the operation mode is an image reverse mode, the data stored in the memory is read out in different sampling orders.
