    • The present invention relates to an apparatus and a method of content retrieval and a program which facilitate recognizing content details of a moving image by displaying a retrieval result for each of a plurality of images.A metadata extracting unit 22 extracts metadata such as information of a representative image from content which is supplied from a content input unit 21 and stores the metadata in a metadata database 24. An image feature quantity extracting unit 23 extracts image feature quantity from content and stores the image feature quantity in an image feature quantity database 25 while extracting image feature quantity from a retrieval image as well. A retrieving unit 27 compares the image feature quantity of the retrieval image with the image feature quantity stored in the image feature quantity database 25 and specifies a still image which is similar to the retrieval image. An output unit 28 reads metadata of the content, generates display data to be necessary for performing timeline displaying, and further, generates display data for displaying a retrieval result on a timeline.
    • 本发明涉及内容检索的装置和方法以及通过显示多个图像中的每个图像的检索结果来便于识别运动图像的内容细节的程序。 元数据提取单元22从内容输入单元21提供的内容中提取诸如代表图像的信息的元数据,并将元数据存储在元数据数据库24中。图像特征量提取单元23从内容中提取图像特征量并存储 同时从检索图像中提取图像特征量的图像特征量数据库25中的图像特征量。 检索单元27将检索图像的图像特征量与存储在图像特征量数据库25中的图像特征量进行比较,并且指定与检索图像相似的静止图像。 输出单元28读取内容的元数据,生成执行时间线显示所必需的显示数据,并且还产生用于在时间轴上显示检索结果的显示数据。
