Claim 10:
11. An object recognition method implemented in an object recognition device for recognizing an object captured on a query image serving as a recognition subject, comprising:
acquiring, by an acquire, from the query image, an increased-resolution image, which is acquired by increasing the resolution of the query image, by performing pre-learned acquisition processing for increasing the resolution of an image;
extracting, by a feature extractor using the increased-resolution image as input, a feature vector of the increased-resolution image by performing pre-learned extraction processing for extracting a feature vector of an image; and
recognizing, by a recognizer, an object captured on the increased-resolution image on the basis of the feature vector of the increased-resolution image and outputs the recognized object as the object captured on the query image, wherein the acquisition processing of the acquirer is acquisition processing learned at least by associating an arbitrary image on which the object is captured with an image acquired by increasing the resolution of a low-resolution image corresponding to the arbitrary image, and during learning, the acquisition processing is optimized at the same time as the extraction processing.
