A method and a device for recognizing a document image, and a photographing method using the same are provided. The method includes extracting, from an input image, a primary feature, including information on feature points, by determining each pixel that is not similar to comparison pixels to be a feature point through a comparison of the pixel to the comparison pixels spaced a predetermined distance apart from the pixel, and classifying the input image as a document image or a non-document image by applying preset primary classification criteria, including criteria for the total number of the feature points to the primary feature.
