Abstract:
1. A display control device comprising: clustering means configured to subject each frame of a content to clustering into any of a plurality of clusters; scene classifying means configured to classify, regarding each of said plurality of clusters, a frame belonging to said each of said plurality of clusters into a scene that is a group of one or more frames that temporally continue; thumbnail creating means configured to create a thumbnail of said scene; and display control means configured to display the thumbnail of said scene on a display device configured to display an image, wherein said clustering means use a state transition model including a state and state transition to subject a frame of said content to clustering into a cluster corresponding to said state, wherein said display control means generate a model map that is a two-dimensional map where states are disposed so that the states of which the state transition can mutually be performed approximate to each other, and perform display control of 2D map display for disposing and displaying, in the position of each state of said model map, the thumbnail of said scene including a frame belonging to a cluster corresponding to the state thereof, and wherein said display control means obtain distance between states from one state to another state of said state transition model based on state transition probability of state transition from said one state to said another state, obtain state coordinates that are the coordinates of the positions of said states on said model map so that difference between Euclidean distance from said one state to said another state is small, and generate said model map where said states that correspond to each other are disposed in the positions of said state coordinates.
