  • Patent number: 8320642
    Abstract: A face collation apparatus has a storage that stores a feature quantity of at least one registrant, the feature quantity being extracted from a registration image of the registrant, a feature quantity extractor that extracts a feature quantity from a collation image of a collation object person, a score calculator that calculates a score indicating an analogy degree between the feature quantity of the registrant and the feature quantity of the collation object person, a score adjuster that adjusts the score using a score adjustment parameter so that any one of a stranger acceptance rate indicating a probability that a stranger is accepted at the time of collation, a principal rejection rate indicating a probability that a principal is rejected at the time of collation, and an equal error rate, which is a probability that the stranger acceptance rate and the principal rejection rate are equal, becomes substantially constant regardless of a registration condition and/or a collation condition, and a determinatio

  • Patent number: 7853052
    Abstract: A face feature value vector extracting section extracts a feature value from a registered image of a registrant to generate a face feature value vector. A virtual face feature value vector generating section converts the face feature value vector using a feature value converter which performs a conversion in a feature value space. Then, a registration information generating section generates face definition information of the registrant based on a face feature value vector before conversion and a virtual face feature value vector after conversion and registers this information in a registration information storing section.

  • Patent number: 7852356
    Abstract: To provide an apparatus capable of easily displaying a magnified image of a subject intended for by the user. An intended subject such as the face of a man is detected from the image displayed on the screen, and in accordance with the position and size of the intended subject detected, the display area and the magnification rate for magnified display of the intended subject are determined. In accordance with the display area and the magnification rate thus determined, the magnified display is conducted on the screen. In the case where a plurality of intended subjects exist in the image, the intended subjects are classified into a plurality of masses and the magnified display may be conducted for each mass.

  • Publication number: 20060115235
    Abstract: A technique by which whole and close-up high-quality moving pictures can be easily photographed, recorded and reproduced. An imaging unit picks up an image at a higher resolution than a resolution of pixels for moving picture recording. An image processing unit converts the resolution of an original image obtained by picking up the image into a whole image of the pixels for moving picture recording, while generating a partial image of the pixels for moving picture recording from a part of the original image. A whole moving picture comprising the whole images and a partial moving picture composed of the partial images are recorded in association with each other.
