Abstract
A control unit controls an image searching system which performs a high quality search for a desired image in an image database by using color information. A sample image determined by an operator is used as a key to the search, and is input to a sample image input unit. A sample color information extraction unit extracts HSV color space data from the sample image, and an image color information extraction unit extracts HSV color image data from a plurality of images stored in the image database. A contribution factors deciding unit decides a contribution factor for each component in the HSV color space, and a candidate image deciding unit calculates a similarity between the plurality of images stored in the database and the sample image. Image candidates are determined based on the calculated similarity, and the image candidates are displayed on a display unit. The desired image is then selected from the displayed image candidates.
