Patent number: 9245168Abstract: An authentication apparatus performs identity authentication by comparing and matching image information of a palm captured by a sensor unit with a preliminarily registered template. A surface information correcting unit corrects concavity/convexity of a palm surface for surface information that allows the concavity/convexity thereof to be evaluated. The surface information is extracted by a surface information extraction unit from the image information obtained by capturing the palm. When the surface information is not corrected by the surface information correcting unit or not used for authentication by an authentication unit even after correction, the authentication apparatus newly obtains image information of the palm. Correction by the surface information correcting unit reduces opportunities for the authentication apparatus to perform notification to guide the palm to a proper posture.Type: GrantFiled: July 26, 2013Date of Patent: January 26, 2016Assignee: FUJITSU FRONTECH LIMITEDInventors: Tomoharu Suzuki, Takehiro Sekikawa, Maki Yabuki, Shinichi Eguchi

Patent number: 9197416Abstract: In a verification apparatus, a biometric information acquisition unit acquires a plurality of biometric information pieces from an object. A first verification unit calculates, as a verification score, the similarity between the biometric information piece and a verification information piece, and compares the calculated verification score with a first determination value to determine whether the biometric information piece matches the verification information piece. When the verification fails, a second verification unit performs verification on the plurality of biometric information pieces having a predetermined relationship, using the verification information piece and a second determination value which defines a less stringent criterion than the first determination value.Type: GrantFiled: August 8, 2013Date of Patent: November 24, 2015Assignee: FUJITSU FRONTECH LIMITEDInventor: Shinichi Eguchi

Authentication apparatus, image capture apparatus, authentication method, and authentication program
Patent number: 8649569Abstract: In an authentication apparatus, an input section acquires a living body image which an image capture apparatus generates by capturing an image of a living body that is an object of authentication, and outputs the living body image to an operation section. When the operation section acquires the living body image from the input section, the operation section calculates, on the basis of the living body image acquired and a registered image stored in a registered image storage section, the difference between the relative position of the living body with respect to the image capture apparatus at the time of acquiring the living body image and the relative position of the living body with respect to the image capture apparatus at the time of acquiring the registered image. The output section outputs guidance information for prompting a reduction in the difference in the relative position calculated by the operation section.Type: GrantFiled: July 19, 2011Date of Patent: February 11, 2014Assignee: Fujitsu Frontech LimitedInventors: Tatsuo Shindo, Tatsuo Kamimura, Naoko Suzuki, Kazuya Ogawa, Shinichi Eguchi, Michitaro Manabe -
Patent number: 8606012Abstract: An image processing method extracts line segment elements from grayscale captured images, so that line segments are extracted at high-speed without being influenced by contrast ratio, even if morphology processing is used. A selection processing select an area where continuous line segments possibly exist from the captured image and a morphology processing detect line segment elements in the selected area by scanning an operator. Line segments can be extracted in a plurality of directions at high-speed. Also by an extraction target area selection processing, an area of which contrast ratio is low, continuing from an area of which contrast ratio is high in the line segment growth direction is also extracted as one line segment.Type: GrantFiled: August 25, 2006Date of Patent: December 10, 2013Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Tomoharu Suzuki, Shinichi Eguchi

Patent number: 8577147Abstract: An objective is to eliminate dotted lines in a character box in image data to increase the character recognition rate. There are some cases in which a dotted line candidate cannot be extracted due to many overlapping parts of dotted lines and characters or due to a blurry part in a dotted line. In such cases, the position of a dotted line candidate is estimated referring to features such as the interval, length, width, etc. of a dotted line candidate in the same character box (or in a character box for another relevant item), and image data of the estimated position and image data of a previously extracted dotted line (or a reference dotted line) are compared to determine whether or not they are an identical dotted line.Type: GrantFiled: June 1, 2011Date of Patent: November 5, 2013Assignee: Fujitsu Frontech LimitedInventors: Shohei Hasegawa, Shinichi Eguchi, Hajime Kawashima, Koichi Kanamoto, Hiroki Inoue, Maki Yabuki, Katsutoshi Kobara

Patent number: 8270680Abstract: A body part guidance control is performed in a non-contact biometrics authentication device which performs individual authentication utilizing characteristics of a body part which is a portion of a human body, for guiding the body part so as to capture images without contact. The future position at the time of message display is predicted by using body part positions of n times in the past and the guidance message can be selected according to this predicted position to output an appropriate message. Hence the time for guidance into an appropriate image capture region can be shortened, the output of messages for movement in the direction opposite the body part movement can be prevented, and inducement of confusion in the user can be prevented, so that the speed of authentication can be improved.Type: GrantFiled: November 20, 2008Date of Patent: September 18, 2012Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Michitaro Manabe, Hiroyuki Takamatsu, Shinichi Eguchi, Kazuhiro Komura, Takayuki Maeta

Patent number: 8229250Abstract: A pattern alignment method performs alignment of the comparison source pattern or the comparison target pattern that has been subjected to the angle-scale conversion with the comparison source pattern. Angular deviations and scale factors between the comparison source pattern and the comparison target pattern are computed separately, after angle and scale conversion, the measured template matching is performed. Therefore, parallel-displacement alignment can be made faster and precise alignment is possible. Template matching processing can be minimized, and aligning can be performed precisely and rapidly.Type: GrantFiled: February 10, 2009Date of Patent: July 24, 2012Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Tomoharu Suzuki, Shinichi Eguchi
