1. A mobile terminal comprising: image capturing means; image obtaining means for obtaining a subject image captured by the image capturing means; image capturing mode determination means for determining, on a basis of a feature point in the subject image thus obtained by the image obtaining means, which one of a plurality of image capturing modes is applicable for the subject image, post-capturing processing means for performing post-capturing processing of the subject image captured by the image capturing means, the image capturing means capturing the subject image, and capturing the subject image again in an image capturing mode determined, on a basis of the subject image, to be applicable by the image capturing mode determination means, and the post-capturing processing means switching a post-processing mode to one corresponding to the image capturing mode determined to be applicable by the image capturing mode determination means and performing, in the post-processing mode, post-capturing processing of the subject image captured again by the image capturing means, if the image capturing mode determination means determines that the character reading mode is applicable, the post-capturing processing is the processing for reading out the character from the subject image, and if the image capturing mode determination means determines that the bar code reading mode is applicable, the post-capturing processing is the processing for reading out the bar code information from the subject image.
