Patent number: 7953252Abstract: A digital image acquisition device is for acquiring digital images including one or more preview images. A face detector analyzes the one or more preview images to ascertain information relating to candidate face regions therein. A speed-optimized filter produces a first set of candidate red-eye regions based on the candidate face region information provided by the face detector.Type: GrantFiled: November 22, 2010Date of Patent: May 31, 2011Assignee: Tessera Technologies Ireland LimitedInventors: Florin Nanu, Adrian Capata, Eran Steinberg, Peter Corcoran, Petronel Bigioi, Alexei Pososin, Mihai Ciuc

Publication number: 20110102643Abstract: 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. A digital apparatus has a red-eye filter which analyzes at least one partial face region identified within the digital image for the red-eye phenomenon and modifies the 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. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.Type: ApplicationFiled: November 8, 2010Publication date: May 5, 2011Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Florin Nanu, Eran Steinberg, Peter Corcoran, Alexei Pososin, Petronel Bigioi, Alexandru Drimbarean, Stefan Petrescu, Mihnea Gangea, Adrian Capata, Mihai Ciuc, Adrian Zamfir

Publication number: 20110074975Abstract: A method of filtering a red-eye phenomenon from an acquired digital image including a multiplicity of pixels indicative of color, the pixels forming various shapes of the image, includes analyzing meta-data information, determining one or more regions within the digital image suspected as including red eye artifact, and determining, based at least in part on the meta-data analysis, whether the regions are actual red eye artifact. The meta-data information may include information describing conditions under which the image was acquired, captured and/or digitized, acquisition device-specific information, and film information.Type: ApplicationFiled: December 1, 2010Publication date: March 31, 2011Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Michael J.

Publication number: 20110063465Abstract: A method for red-eye detection in an acquired digital image includes acquiring a first image, and analyzing one or more partial face regions within the first image. One or more characteristics of the first image are determined. One or more corrective processes are identified including red eye correction that can be beneficially applied to the first image according to the one or more characteristics. The one or more corrective processes are applied to the first image.Type: ApplicationFiled: July 13, 2010Publication date: March 17, 2011Applicant: FOTONATION IRELAND LIMITEDInventors: Florin Nanu, Eran Steinberg, Peter Corcoran, Alexei Pososin, Petronel Bigioi, Alexandru Drimbarean, Stefan Petrescu, Mihnea Gangea, Adrian Capata, Mihai Ciuc, Adrian Zamfir

Patent number: 7864990Abstract: An image processing apparatus for tracking faces in an image stream iteratively receives a new acquired image from the image stream, the image potentially including one or more face regions. The acquired image is sub-sampled (112) at a specified resolution to provide a sub-sampled image. An integral image is then calculated for a least a portion of the sub-sampled image. Fixed size face detection (20) is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution at which a next acquired image is sub-sampled is adjusted.Type: GrantFiled: December 11, 2008Date of Patent: January 4, 2011Assignee: Tessera Technologies Ireland LimitedInventors: Peter Corcoran, Alexandru Drimbarean, Alexei Pososin, Petronel Bigioi, Eran Steinberg, Stefan Petrescu, Florin Nanu

Publication number: 20100329549Abstract: A method for providing improved foreground/background separation in a digital image of a scene is disclosed. The method comprises providing a first map comprising one or more regions provisionally defined as one of foreground or background within the digital image; and providing a subject profile corresponding to a region of interest of the digital image. The provisionally defined regions are compared with the subject profile to determine if any of the regions intersect with the profile region. The definition of one or more of the regions in the map is changed based on the comparison.Type: ApplicationFiled: September 10, 2010Publication date: December 30, 2010Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Alexei Pososin, Mihai Ciuc, Adrian Zamfir, Adrian Capata
