1. A method of providing primitive visual knowledge performed by a primitive visual knowledge providing apparatus, the method comprising: receiving an image video in a form of a digital image sequence; dividing the received image video into scenes; extracting a representative shot from each of the scenes; extracting objects from frames which compose the representative shot; extracting action verbs based on a mutual relationship between the extracted objects; selecting a frame best expressing the mutual relationship with the objects, which are the basis for the extracting of the action verbs, as a key frame; generating the primitive visual knowledge based on the selected key frame; storing the generated primitive visual knowledge in a database; and visualizing the primitive visual knowledge stored in the database to provide the primitive visual knowledge to a manager, wherein the extracting of the representative shot includes: calculating an entropy in a section while moving along sections of separate scenes; and extracting a section having the highest entropy as the representative shot.
