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: 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

Patent number: 9019402Abstract: Two or more digital images of a same scene are captured with different exposure levels. Image pairs are generated that have a same exposure level from the image data of differently exposed images by adjusting the exposure of at least one of the pair of images. A ghosting map is generated based on differences between the pair of images adjusted to the same exposure. A blurred ghosting map is generated and alpha blending is performed.Type: GrantFiled: August 8, 2013Date of Patent: April 28, 2015Assignee: FotoNation LimitedInventors: Ruxandra Vränceanu, Razvan George Condorovici, Foti Coleca, Corneliu Florea

Patent number: 8737766Abstract: A method and apparatus for providing image processing. For one embodiment of the invention, 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: February 20, 2013Date of Patent: May 27, 2014Assignee: DigitalOptics Corporation Europe LimitedInventors: Felix Albu, Eran Steinberg, Alexandru Drimbarean, Corneliu Florea, Adrian Zamfir, Peter Corcoran, Vlad Poenaru

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

Publication number: 20140078322Abstract: 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: August 26, 2013Publication date: March 20, 2014Applicant: DigitalOptics Corporation Europe LimitedInventors: Peter Corcoran, Eran Steinberg, Petronel Bigioi, Alexandru Drimbarean, Adrian Zamfir, Corneliu Florea
