Abstract
The symbol data read apparatus comprises a two-dimensional image pick-up device for picking up a bar-code symbol consisting of bars and spaces, as a two-dimensional image. A frame memory stores the two-dimensional image from the two-dimensional image pick-up device, as bar-code symbol data. A condition detect section detects a bar-code condition of the bar-code symbol from the bar-code symbol data stored in the frame memory. A decode section performs decode-processing to obtain original bar-code symbol data on the basis of bar-code condition data from the condition detect section and the bar-code symbol data from the frame memory. An output select section selectively outputs at least data other than the original bar-code symbol data out of the original bar-code symbol data and the other data than the original bar-code symbol data. The other data than the original bar-code symbol data includes inclination data concerning the bar-code symbol and a weighting value for every block.
