Abstract
An optical information reading apparatus includes a two-dimensional image pickup apparatus having a number of photoelectric conversion elements arranged in a plane for capturing an image of optical information on a read object. The optical information reading apparatus detects a bar code contained in the captured information image and derives an area of each of bars and spaces of the bar code in the captured information image. The optical information reading apparatus recognizes and decodes the bar code using a ratio of the derived areas of the bars and the spaces of the bar code.
