Abstract:
1. A barcode reading apparatus to read a barcode image from image data of a taken image, the apparatus comprising: a capturing section to, in capturing a one-frame image, (i) divide the one-frame image into a plurality of image areas so that the image areas with different focus positions exist in the one-frame image, and (ii) change a focus position with respect to each of the image areas so as to capture images of the image areas with the different focus positions; and a generating section to combine the images of the image areas captured by the capturing section so as to generate image data of the one-frame image, wherein the barcode reading apparatus has multiple types of focus position patterns with each of which the capturing section changes the focus position with respect to each of the image areas, wherein the capturing section selects a focus position pattern from among the focus position patterns, and, in accordance with the selected focus position pattern, (i) divides the one-frame image into the plurality of image areas and (ii) changes the focus position with respect to each of the image areas so as to capture the images of the image areas with the different focus positions, and wherein the barcode reading apparatus further comprises:
