Patent number: 10628568Abstract: A biometric recognition system for a hand held computing device incorporating an inertial measurement unit (IMU) comprising a plurality of accelerometers and at least one gyroscope is disclosed. A tremor analysis component is arranged to: obtain from the IMU, accelerometer signals indicating device translational acceleration along each of X, Y and Z axes as well as a gyroscope signal indicating rotational velocity about the Y axis during a measurement window. Each of the IMU signals is filtered to provide filtered frequency components for the signals during the measurement window. The accelerometer signals are combined to provide a combined filtered accelerometer magnitude signal for the measurement window. A spectral density estimation is provided for each of the combined filtered accelerometer magnitude signal and the filtered gyroscope signal.Type: GrantFiled: March 29, 2017Date of Patent: April 21, 2020Assignee: FotoNation LimitedInventors: Adrian Zamfir, Andreea Oana Miu, Corneliu Florea

Patent number: 9684966Abstract: 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: GrantFiled: August 24, 2015Date of Patent: June 20, 2017Assignee: FotoNation LimitedInventors: Eran Steinberg, Peter Corcoran, Yury Prilutsky, Petronel Bigioi, Alexei Pososin, Mihai Ciuc, Adrian Zamfir, Adrian Capata

Publication number: 20170070649Abstract: 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: August 9, 2016Publication date: March 9, 2017Inventors: Florin NANU, Eran STEINBERG, Stefan PETRESCU, Mihnea GANGEA, Adrian CAPATA, Mihai CIUC, Adrian ZAMFIR, Peter CORCORAN, Alexei POSOSIN, Petronel BIGIOI, Alexandru DRIMBAREAN

Patent number: 9160897Abstract: An estimated total camera motion between temporally proximate image frames is computed. A desired component of the estimated total camera motion is determined including distinguishing an undesired component of the estimated total camera motion, and including characterizing vector values of motion between the image frames. A counter is incremented for each pixel group having a summed luminance that is greater than a threshold. A counter may be decremented for pixels that are under a second threshold, or a zero bit may be applied to pixels below a single threshold. The threshold or thresholds is/are determined based on a dynamic luminance range of the sequence. The desired camera motion is computed including representing the vector values based on final values of counts for the image frames. A corrected image sequence is generated including the desired component of the estimated total camera motion, and excluding the undesired component.Type: GrantFiled: June 11, 2008Date of Patent: October 13, 2015Assignee: FotoNation LimitedInventors: Felix Albu, Corneliu Florea, Adrian Zamfir, Alexandru Drimbarean, Peter Corcoran

Publication number: 20150103190Abstract: An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds a threshold. A controller selectively transfers acquired images for storage. A motion extractor determines motion parameters of a selected, stored image. An image re-constructor corrects the selected image with associated motion parameters. A selected plurality of images nominally of the same scene are merged and corrected by the image re-constructor to produce a high quality image of the scene.Type: ApplicationFiled: October 16, 2014Publication date: April 16, 2015Inventors: Peter Corcoran, Petrenol Bigioi, Alexandru Drimbarean, Adrian Zamfir, Corneliu Florean

Patent number: 8989516Abstract: An image processing apparatus is arranged to process a first relatively underexposed and sharp image of a scene, and a second relatively well exposed and blurred image, nominally of the same scene, the first and second images being derived from respective image sources. The apparatus provides a portion of the relatively first underexposed image as an input signal to an adaptive filter; and a corresponding portion of the second relatively well exposed image as a desired signal to the adaptive filter. The adaptive filter produces an output signal from the input signal and the desired signal; and an image generator constructs a first filtered image from the output signal, relatively less blurred than the second image.Type: GrantFiled: December 16, 2008Date of Patent: March 24, 2015Assignee: FotoNation LimitedInventors: Felix Albu, Adrian Zamfir

Patent number: 8879869Abstract: 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: January 23, 2013Date of Patent: November 4, 2014Assignee: DigitalOptics Corporation Europe LimitedInventors: Marta Zamfir, Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi, Adrian Zamfir

Patent number: 8698924Abstract: A technique is provided for generating sharp, well-exposed, color images from low-light images. A series of under-exposed images is acquired. A mean image is computed and a sum image is generated each based on the series of under-exposed images. Chrominance variables of pixels of the mean image are mapped to chrominance variables of pixels of the sum image. Chrominance values of pixels within the series of under-exposed images are replaced with chrominance values of the sum image. A set of sharp, well-exposed, color images is generated based on the series of under-exposed images with replaced chrominance values.Type: GrantFiled: November 8, 2010Date of Patent: April 15, 2014Assignee: DigitalOptics Corporation Europe LimitedInventors: Alexandru Drimbarean, Adrian Zamfir, Felix Albu, Vlad Poenaru, Corneliu Florea, Petronel Bigioi, Eran Steinberg, Peter Corcoran
