Video structuring device and method
A video structuring device includes: character string extraction means for determining whether or not a character string is present in a frame image, and if it determines that a character string is present, generating character string position information for the character string present in a character string present frame image in which the character string is present, and outputting the character string position information, frame identifying information for identifying the character string present frame image, and the character string present frame image; video information storage means for storing frame identifying information, character string present frame image and character string position information in an index file all associated with one another; and structure information presentation means for associating character string display in the form of an image which is produced by cutting an area where the character string is present based on the character string present frame image and character string position information stored in the index file and displaying them on display means.
1. A video structuring device, comprising:
video input means for receiving a video signal and outputting a frame image of a video and frame identifying information which identifies the frame image;
character string extraction means for receiving said frame image and said frame identifying information from said video input means to determine whether or not a character string is present in the frame image, and if it determines that a character string is present in the frame image, generating character string position information for the character string present in the frame image as a character string present frame image, and outputting the character string position information, frame identifying information for identifying said character string present frame image and said character string present frame image;
video information storage means for obtaining said frame identifying information, said character string present frame image and said character string position information from said character string extraction means, and storing the obtained pieces of information associated with one another in an index file; and
structure information presentation means for reading out said index file from said video information storage means, cutting out an area in which a character string is present from said character string present frame image based on said character string position information, and displaying a character string display in a form of said cut-out image on display means being associated with frame identifying information for identifying said character string present frame image.
