Title:
DEVICE AND METHOD FOR DETECTING IMAGE, DIGITAL CAMERA AND PRINTER
Document Type and Number:
Japanese Patent JP3438719
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To exactly detect whether or not an image similar to a prescribed retrieving image at least exists in an input image as a retrieval target even when there are a little image data.
SOLUTION: An HQ histogram preparing part 4 decides whether the number of pixels in a partial area and the retrieving image is less than a prescribed value or not and when it is less than the prescribed value, a color histogram, to which smoothing processing is applied, is prepared. An HQ histogram comparing part 5 compares the partial area of the input image with the color histogram of the retrieving image. A similarity deciding part 6 finds the similarity of compared color histograms, decides whether similarity thereof is higher than a prescribed level or not and defines the partial area higher than the prescribed level as a detection area, where the retrieving image exists.
