Abstract
According to one embodiment, a code symbol reading apparatus includes a decoder, a candidate area detection unit, a direction determination unit, and a direction notification unit. The decoder decodes a code symbol attached to an article, based on an image picked up by a camera. The candidate area detection unit detects an image area to be a candidate of the code symbol from the image of the article picked up by the camera. The direction determination unit determines such a direction that a decoding rate of the code symbol becomes higher based on the image area detected by the candidate area detection unit when the decoder cannot decode the code symbol. The direction notification unit notifies of the direction determined by the direction determination unit.
