ABSTRACT:
An image retrieving apparatus that can suitably retrieve a similar image of image data whose density has changed. Image data is inputted from image input unit12. Image feature amount extraction unit14divides normalized image data to plural regions, and extracts a feature amount in units of region. Feature amount label matrixing unit15generates a feature amount matrix. The feature amount matrix and image data are stored in image management DB18in association with each other. When query image data is designated, pattern matching unit16determines a similarity level between a feature amount matrix of the query image data and the feature amount matrix of the image data stored in the image management DB18.
