Database Production Method, Database Production Program, Database Production Apparatus and Image Content Recording Apparatus

A database production program for causing a computer to execute:

• a representative image selection step of selecting certain images each as a representative image which represents an image content from the image content;
• a display processing step of causing a display apparatus to display the representative image;
• an operation inputting step of allowing a user to input image text information corresponding to the representative image;
• and
• a database production step of registering representative characteristic information extracted from the representative image in accordance with a predetermined extraction method and the image text information inputted at the operation inputting step in an associated relationship with each other to produce a database for acquiring, using arbitrary image characteristic information for each image extracted from an arbitrary image content in accordance with the extraction method, substance character information corresponding to an image which the arbitrary image content has.

A database production apparatus, comprising:

• a representative image selection section configured to select certain images each as a representative image which represents an image content from the image content;
• a display processing section configured to cause a display apparatus to display the representative image;
• an operation inputting section configured to allow a user to input image text information corresponding to the representative image;
• and
• a database production section configured to register representative characteristic information extracted from the representative image in accordance with a predetermined extraction method and the image text information inputted by said operation inputting section in an associated relationship with each other to produce a database for acquiring, using arbitrary image characteristic information for each image extracted from an arbitrary image content in accordance with the extraction method, substance character information corresponding to an image which the arbitrary image content has.

An image content recording apparatus, comprising:

• a recording section configured to record an image content;
• a representative image selection section configured to select certain images each as a representative image which represents the image content from the image content;
• a display processing section configured to cause a display apparatus to display the representative image;
• an operation inputting section configured to allow a user to input image text information corresponding to the representative image;
• and
• a database production section configured to register representative characteristic information extracted from the representative image in accordance with a predetermined extraction method and the image text information inputted by said operation inputting section in an associated relationship with each other to produce a database for acquiring, using arbitrary image characteristic information for each image extracted from an arbitrary image content in accordance with the extraction method, substance character information corresponding to an image which the arbitrary image content has.
