PROBLEM TO BE SOLVED: To provide an information terminal device capable of precisely correcting an imaging target from an imaged image.SOLUTION: An extraction part 2 extracts a feature region of an extraction target which is already known from an image that is inputted from an imaging part 1. A correction part 3 selects a feature candidate from the feature region, corrects distortion of the imaged image by making correspondence to the extraction target, discriminates an optimum feature candidate by comparing the correction image with the extraction target, for outputting a correction image corresponding to the optimum feature candidate. Here, a feature candidate of which difference between the correction image and the extraction target is minimum is discriminated as optimum one. |
