Abstract
There are provided a comparison device and a comparison method including determining whether or not a comparison target person is a subject of a registered face image by comparing an imaged face image to the registered face image, determining whether or not a blocking object is provided in the imaged face image, determining whether or not removing the blocking object is required, by calculating a partial similarity score between the imaged face image and the registered face image in a partial area corresponding to the blocking object, and urging the blocking object to be detached based on the partial similarity score.
