Publication number: 20120206618Abstract: A measure of frame-to-frame rotation is determined. A global XY alignment of a pair of image frames is performed. At least one section of each of the X and Y integral projection vectors is determined, where aligned global vectors demonstrate a significant localized difference. Based on X and Y locations of the at least one section of the X and Y integral projection vectors, location, relative velocity and/or approximate area of at least one moving object within the sequence of image frames is/are determined.Type: ApplicationFiled: February 15, 2011Publication date: August 16, 2012Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Felix Albu, Larry Murray, Piotr Stec, Ilariu Raducan

Publication number: 20120207347Abstract: A measure of frame-to-frame rotation is determined. Integral projection vector gradients are determined and normalized for a pair of images. Locations of primary maximum and minimum peaks of the integral projection vector gradients are determined. Based on normalized distances between the primary maximum and minimum peaks, a global image rotation is determined.Type: ApplicationFiled: February 15, 2011Publication date: August 16, 2012Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Felix Albu, Larry Murray, Piotr Stec, Ilariu Raducan

Publication number: 20120206617Abstract: A measure of frame-to-frame rotation is determined. A global XY alignment of a pair of frames is performed. Local XY alignments in at least two matching corner regions of the pair of images are determined after the global XY alignment. Based on differences between the local XY alignments, a global rotation is determined between the pair of frames.Type: ApplicationFiled: February 15, 2011Publication date: August 16, 2012Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Felix Albu, Larry Murray, Piotr Stec, Ilariu Raducan

Publication number: 20120177289Abstract: Methods and systems for detecting and correcting chromatic aberration and purple fringing are disclosed. Chromatic aberration can be addressed by separating an image into color planes and then adjusting these to reduce chromatic aberration by using a specific calibration image (calibration chart) as an empirical method to calibrate the image acquisition device. Purple fringing can be corrected by initially addressing color aberration resulting from the lateral chromatic aberration (LCA). The LCA is first removed and then the correction is extended to purple fringing. A discovery is relied upon that the purple fringing is created in the direction of the chromatic aberration and is more pronounced in the direction of the chromatic aberration.Type: ApplicationFiled: July 22, 2011Publication date: July 12, 2012Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Piotr Stec, Larry Murray, Alexandru Drimbarean

Publication number: 20120133746Abstract: A hand-held digital image capture device (digital camera) has a user-selectable mode in which upon engaging the mode the device detects a face in the field of view of the device and generates a face delimiter on a camera display screen, the delimiter surrounding the initial position of the image of a the face on the screen. The device is arranged to indicate thereafter to the user if the device departs from movement along a predetermined concave path P with the optical axis of the device pointing towards the face, such indication being made by movement of the image of the face relative to the delimiter. The camera captures and stores a plurality of images at successive positions along the concave path.Type: ApplicationFiled: November 29, 2011Publication date: May 31, 2012Applicant: DIGITALOPTICS CORPORATION EUROPE LIMITEDInventors: Petronel Bigioi, Peter Corcoran, Piotr Stec

Publication number: 20120019613Abstract: A technique of generating a stereoscopic panorama image includes panning a portable camera device, and acquiring multiple image frames. Multiple at least partially overlapping image frames are acquired of portions of the scene. The method involves registering the image frames, including determining displacements of the imaging device between acquisitions of image frames. Multiple panorama images are generated including joining image frames of the scene according to spatial relationships and dynamically determining stereoscopic counterpart relationships between the multiple panorama images. The multiple panorama images are processed based on the dynamically determined stereoscopic counterpart relationships to form a stereoscopic panorama image.Type: ApplicationFiled: June 30, 2011Publication date: January 26, 2012Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Larry Murray, Igor Barcovschi, Piotr Stec, James Harkin, Petronel Bigioi, George Susanu, Alexandru Drimbarean, Peter Corcoran

Publication number: 20110216156Abstract: An image acquisition device having a wide field of view includes a lens and image sensor configured to capture an original wide field of view (WFoV) image with a field of view of more than 90°. The device has an object detection engine that includes one or more cascades of object classifiers, e.g., face classifiers. A WFoV correction engine may apply rectilinear and/or cylindrical projections to pixels of the WFoV image, and/or non-linear, rectilinear and/or cylindrical lens elements or lens portions serve to prevent and/or correct distortion within the original WFoV image. One or more objects located within the original and/or distortion-corrected WFoV image is/are detectable by the object detection engine upon application of the one or more cascades of object classifiers.Type: ApplicationFiled: December 2, 2010Publication date: September 8, 2011Applicant: TESSERA TECHNOLOGIES IRELAND LIMITEDInventors: Petronel Bigioi, Alexandru Drimbarean, Mihnea Gangea, Piotr Stec, Peter Corcoran

Publication number: 20110141225Abstract: A technique of generating a panoramic image involves acquiring a set of at least two main image frames, as well as corresponding generating and/or acquiring corresponding relatively low-resolution image frames, of overlapping portions of a panoramic scene. A map or other information is stored relating to the generation of a low-res panorama. A main panorama image is formed by joining main image frames based on the map or other information gained in the low-res process.Type: ApplicationFiled: December 11, 2009Publication date: June 16, 2011Applicant: FotoNation Ireland LimitedInventors: Piotr Stec, Larry Murray, Alexandru Drimbarean, Igor Barcovschi, Peter Corcoran
