Publication number: 20100066822Abstract: A processor-based system operating according to digitally-embedded programming instructions performs a method including identifying a group of pixels corresponding to a face region within digital image data acquired by an image acquisition device. A set of face analysis parameter values is extacted from said face region, including a faceprint associated with the face region. First and second reference faceprints are determined for a person using reference images captured respectively in predetermined face-portrait conditions and using ambient conditions. The faceprints are analyzed to determine a baseline faceprint and a range of variability from the baseline associated with the person. Results of the analyzing are stored and used in subsequent recognition of the person in a subsequent image acquired under ambient conditions.Type: ApplicationFiled: September 4, 2009Publication date: March 18, 2010Applicant: FotoNation Ireland LimitedInventors: Eran Steinberg, Peter Corcoran, Petronel Bigioi, Mihai Ciuc, Stefanita Ciurel, Constantin Vertran

Patent number: 7680342Abstract: An analysis and classification tool compares at least a portion of a captured image and a reference image of nominally the same scene. One of the captured and reference images is taken with flash and the other is taken without flash. The tool provides a measure of the difference in illumination between the captured image and the reference image. The tool compares the measure with a threshold and categorizes the scene as outdoor or indoor based on the measure.Type: GrantFiled: May 30, 2006Date of Patent: March 16, 2010Assignee: FotoNation Vision LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi

Patent number: 7676108Abstract: A digital image acquisition system includes a portable apparatus for capturing digital images and a digital processing component for detecting, analyzing, invoking subsequent image captures and informing the photographer regarding motion blur, and for reducing camera motion blur in an image captured by the apparatus. The digital processing component operates by comparing the image with at least one other image, for example a preview image, of nominally the same scene taken outside the exposure period of the main image. In one embodiment the digital processing component identifies at least one feature in a single preview image which is relatively less blurred than the corresponding feature in the main image, calculates a point spread function (PSF) in respect of such feature, and initiates a subsequent capture if determined that the motion blur exceeds a certain threshold.Type: GrantFiled: August 27, 2008Date of Patent: March 9, 2010Assignee: FotoNation Vision LimitedInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky

Patent number: 7676110Abstract: A method of automatically determining a need to service a digital image acquisition system including a digital camera with a lens assembly includes analyzing pixels within one or more acquired digital images according to probability determinations that such pixels correspond to blemish artifacts. It is automatically determined whether a threshold distribution of blemish artifacts is present within one or more of the digital images. A need for service is indicated when at least the threshold distribution is determined to be present.Type: GrantFiled: September 30, 2003Date of Patent: March 9, 2010Assignee: FotoNation Vision LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi, Adrian Zamfir, Vasile Buzuloiu, Danutz Ursu, Marta Zamfir

Publication number: 20100014721Abstract: A processor-based system operating according to digitally-embedded programming instructions includes a face detection module for identifying face regions within digital images. A normalization module generates a normalized version of the face region. A face recognition module automatically extracts a set of face classifier parameter values from the normalized face region that are referred to as a faceprint. A workflow module automatically compares the extracted faceprint to a database of archived faceprints previously determined to correspond to known identities. The workflow module determines based on the comparing whether the new faceprint corresponds to any of the known identities, and associates the new faceprint and normalized face region with a new or known identity within a database. A database module serves to archive data corresponding to the new faceprint and its associated parent image according to the associating by the workflow module within one or more digital data storage media.Type: ApplicationFiled: July 20, 2009Publication date: January 21, 2010Applicant: FotoNation Ireland LimitedInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Mihai Ciuc, Stefanita Ciurel, Constantin Vertran

Method of improving orientation and color balance of digital images using face detection information
Patent number: 7630527Abstract: A method of generating one or more new spatial and chromatic variation digital images uses an original digitally-acquired image which including a face or portions of a face. A group of pixels that correspond to a face within the original digitally-acquired image is identified. A portion of the original image is selected to include the group of pixels. Values of pixels of one or more new images based on the selected portion are automatically generated, or an option to generate them is provided, in a manner which always includes the face within the one or more new images. Such method may be implemented to automatically establish the correct orientation and color balance of an image. Such method can be implemented as an automated method or a semi automatic method to guide users in viewing, capturing or printing of images.Type: GrantFiled: June 20, 2007Date of Patent: December 8, 2009Assignee: FotoNation Ireland LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi -
Patent number: 7620218Abstract: A method of tracking a face in a reference image stream using a digital image acquisition device includes acquiring a full resolution main image and an image stream of relatively low resolution reference images each including one or more face regions. One or more face regions are identified within two or more of the reference images. A relative movement is determined between the two or more reference images. A size and location are determined of the one or more face regions within each of the two or more reference images. Concentrated face detection is applied to at least a portion of the full resolution main image in a predicted location for candidate face regions having a predicted size as a function of the determined relative movement and the size and location of the one or more face regions within the reference images, to provide a set of candidate face regions for the main image.Type: GrantFiled: June 17, 2008Date of Patent: November 17, 2009Assignee: FotoNation Ireland LimitedInventors: Eran Steinberg, Petronel Bigioi, Peter Corcoran, Alexei Pososin, Alexandru Drimbarean, Florin Nanu, Stefan Petrescu

Patent number: 7619665Abstract: A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. The digital camera has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject.Type: GrantFiled: April 19, 2006Date of Patent: November 17, 2009Assignee: FotoNation Ireland LimitedInventor: Michael J.
