Publication number: 20090273685Abstract: An implementation efficient method of distinguishing between foreground and background regions of a digital image of a scene includes capturing two images of nominally the same scene and storing the captured images in DCT-coded format. The first image is taken with the foreground more in focus than the background and the second image is taken with the background more in focus than the foreground. Regions of the first image are assigned as foreground or background according to whether the sum of selected higher order DCT coefficients decreases or increases for the equivalent regions of the second image.Type: ApplicationFiled: August 21, 2006Publication date: November 5, 2009Applicant: FOTONATION VISION LIMITEDInventors: Mihai Ciuc, Adrian Zamfir, Adrian Capata, Peter Corcoran, Eran Steinberg

Patent number: 7599577Abstract: A method for digital image eye artifact detection and correction include identifying one or more candidate red-eye defect regions in an acquired image. For one or more candidate red-eye regions, a seed pixels and/or a region of pixels having a high intensity value in the vicinity of the candidate red-eye region is identified. The shape, roundness or other eye-related characteristic of a combined hybrid region including the candidate red-eye region and the region of high intensity pixels is analyzed. Based on the analysis of the eye-related characteristic of the combined hybrid region, it is determined whether to apply flash artifact correction, including red eye correction of the candidate red-eye region and/or correction of the region of high intensity pixels.Type: GrantFiled: November 18, 2005Date of Patent: October 6, 2009Assignee: FotoNation Vision LimitedInventors: Mihai Ciuc, Adrian Capata, Florin Nanu, Eran Steinberg, Peter Corcoran

Publication number: 20090196466Abstract: A method for detecting a face in a mid-shot digital image of a person comprises capturing first and second mid-shot digital images of nominally the same scene using different capture settings such that the foreground is differently differentiated from the background in each image, and comparing the first and second images to determine the foreground region of the images. A portion of the foreground region likely to correspond to a face is estimated based upon the geometry of the foreground region.Type: ApplicationFiled: February 5, 2008Publication date: August 6, 2009Applicant: FotoNation Vision LimitedInventors: Adrian Capata, Vlad Poenaru, Eran Steinberg

Publication number: 20090167893Abstract: A color filter enhancement method for a portable digital image acquisition device includes digitally exposing color pixels of a color sensor array for a first digital exposure duration and digitally exposing white pixels of a color sensor array for a second digital exposure time shorter than the first digital exposure duration. A color filter enhanced digital image is generated using data from both the color pixels exposed for the first digital exposure duration and the white pixels exposed for the second digital exposure duration.Type: ApplicationFiled: December 9, 2008Publication date: July 2, 2009Applicant: FOTONATION VISION LIMITEDInventors: George Susanu, Stefan Petrescu, Florin Nanu, Adrian Capata, Peter Corcoran

Publication number: 20090080796Abstract: A method and apparatus for providing defect correction in blurred images is disclosed. For one embodiment of the invention, a digital image is acquired. One or more candidate defect regions in the image are identified. The candidate defect regions are corrected and responsive to the image being blurred, the corrected regions of the image are blurred. For one embodiment of the invention, a digital image is acquired and one or more candidate eye defect regions in the image are identified. The candidate eye defect regions are corrected and if the image is blurred, the corrected regions of the image are blurred accordingly.Type: ApplicationFiled: September 21, 2007Publication date: March 26, 2009Applicant: FotoNation Vision LimitedInventors: Adrian Capata, Florin Nanu, Alexandru Drimbarean

Patent number: 7474341Abstract: 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 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. The detection and correction can be optimized for performance and quality by operating on subsample versions of the image when appropriate.Type: GrantFiled: June 27, 2007Date of Patent: January 6, 2009Assignee: FotoNation Vision LimitedInventors: Michael J. DeLuca, Yury Prilutsky, Eran Steinberg, Peter Corcoran, Alexei Pososin, Petronel Bigioi, Alexandru Drimbarean, Adrian Capata, Florin Nanu

Publication number: 20080316328Abstract: A technique involves distinguishing between foreground and background regions of a digital image of a scene. First and second images are captured of nominally a same scene. The first image is a relatively high resolution image taken with the foreground more in focus than the background, while the second image is a relatively low resolution reference image taken with the background more in focus than the foreground. Regions of the captured images are assigned as foreground or background. In accordance with the assigning, one or more processed images are rendered based on the first image or the second image, or both.Type: ApplicationFiled: June 17, 2008Publication date: December 25, 2008Applicant: FotoNation Ireland LimitedInventors: Eran Steinberg, Petronel Bigioi, Adrian Zamfir, Alexandru Drimbarean, Peter Corcoran, Mihai Ciuc, Adrian Capata

Publication number: 20080112599Abstract: A method for detecting redeye in a digital image comprises initially examining the image to detect redeyes, examining the image to detect face regions and, from the results of the preceding examinations, identifying those detected face regions each including only one detected redeye. Next, the identified face regions are examined, using less stringent search criteria than the initial examination, to detect additional redeyes in the face regions.Type: ApplicationFiled: November 7, 2007Publication date: May 15, 2008Applicant: FotoNation Vision LimitedInventors: Florin Nanu, Peter Corcoran, Adrian Capata, Alexandru Drimbarean, Eran Steinberg

Publication number: 20070269108Abstract: 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: May 3, 2007Publication date: November 22, 2007Applicant: FOTONATION VISION LIMITEDInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Alexei Pososin, Mihai Ciuc, Adrian Zamfir, Adrian Capata

Publication number: 20070147820Abstract: A digital image acquisition system having no photographic film comprises an apparatus for capturing digital images and a flash unit for providing illumination during image capture. The system has a portrait mode for generating an image of a foreground object against a blurred background, the portrait mode being operable to capture first, second and third images (A, B and C) of nominally the same scene. One of the first and second images (A, B) is taken with flash and the other is taken without flash, and the third image (C) is blurred compared to the first and second images. The portrait mode is further operable to determine foreground and background regions of the scene using the first and second images (A, B), and to substitute the blurred background of the third image (C) for the background of an in-focus image of the scene. In one embodiment the in-focus image is one of the first and second images. In another embodiment the in-focus image is a fourth image.Type: ApplicationFiled: December 27, 2005Publication date: June 28, 2007Inventors: Eran Steinberg, Adrian Zamflr, Adrian Capata, Peter Corcoran
