摘要

The present invention provides advertisement information pertaining to a subject in real time while imaging the subject. In the present invention, m first local feature quantities each comprising a one-dimensional to i-dimensional feature vector are recorded associated with the subject, n features are extracted from a video, n second local feature quantities are generated each comprising a one-dimensional to j-dimensional feature vector, the lower dimensionality is selected among dimensionality i and dimensionality j, and when it is determined that at least a predetermined fraction of the m first local feature quantities of the selected dimensionality correspond to the n second local feature quantities of the selected dimensionality, the subject is recognized as being present in the video and advertisement information pertaining to the subject is provided.
