Patent number: 9275464Abstract: Embodiments are directed towards determining within a digital camera whether a pixel belongs to a foreground or background segment within a given image by evaluating a ratio of derivative and deviation metrics in an area around each pixel in the image, or ratios of derivative metrics across a plurality of images. For each pixel within the image, a block of pixels are examined to determine an aggregate relative derivative (ARD) in the block. The ARD is compared to a threshold value to determine whether the pixel is to be assigned in the foreground segment or the background segment. In one embodiment, a single image is used to determine the ARD and the pixel segmentation for that image. Multiple images may also be used to obtain ratios of a numerator of the ARD, useable to determine an extent of the foreground.Type: GrantFiled: July 25, 2014Date of Patent: March 1, 2016Assignee: QUALCOMM Technologies, Inc.Inventor: Noam Levy

Patent number: 9210405Abstract: Embodiments are directed towards enabling digital cameras to digitally process captured two dimensional image sequences at a real time video rate, to convert the two dimensional image sequences into stereoscopic three dimensional image sequences. In one embodiment, using a pipelining architecture, various statistics are obtained for a captured two dimensional sequence. The statistics are used to estimate depth within each frame image within the sequence, in real time. Using the depth data a disparity map is generated that is provided to a warping component to generate a second perspective of the two dimensional image. The two images for the frame provide a three dimensional perspective for the frame within the sequence. Together the two perspective images for the frame are provided to a video encoder component to encode the stereoscopic three dimensional frame for the sequence.Type: GrantFiled: March 22, 2012Date of Patent: December 8, 2015Assignee: QUALCOMM TECHNOLOGIES, INC.Inventor: Noam Levy

Publication number: 20140267602Abstract: Embodiments are directed towards enabling digital cameras to create a 3D view, which can be re-rendered onto any object within a scene, so that it is both in focus and a center of perspective, based on capturing a single set of multiple 2D images of the scene. From capturing a single set of 2D images for a scene, a depth map of the scene may be generated, and used to calculate principal depths, which are then used to capture an image focused at each of the principal depths. A correspondence between a 2D image of the scene and the principal depths are determined that corresponds to a specific principal depth. For different coordinates of the 2D image, different 3D views of the scene are created that are each focused at a principal dept that corresponds to the given coordinate.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Applicant: CSR Technology, Inc.Inventors: Meir Tzur, Noam Levy

Publication number: 20140002694Abstract: Embodiments are directed towards enabling digital cameras to digitally process a captured a Low Dynamic Range image sequence at a real time video rate, and to convert the image sequence into an High Dynamic Range (HDR) image sequence using a pipelined architecture. Two or more image frames are captured using different exposure settings and then combined to form a single HDR output frame in a video sequence. The pipelined architecture operate on adjacent image frames by performing an image alignment, an image mixing, and a tone mapping on the adjacent image frames to generate the HDR image sequence.Type: ApplicationFiled: July 2, 2012Publication date: January 2, 2014Applicant: CSR Technology Inc.Inventors: Noam Levy, Guy Rapaport

Patent number: 8554014Abstract: A camera that provides for a panorama mode of operation that employs internal software and internal acceleration hardware to stitch together two or more captured images to create a single panorama image with a wide format. Captured images are projected from rectilinear coordinates into cylindrical coordinates with the aid of image interpolation acceleration hardware. Matches are quickly determined between each pair of images with a block based search that employs motion estimation acceleration hardware. Transformation are found, utilizing regression and robust statistics techniques, to align the captured images with each other, which are applied to the images using the interpolation acceleration hardware. A determination is made for an optimal seam to stitch images together in the overlap region by finding a path which cuts through relatively non-noticeable regions so that the images can be stitched together into a single image with a wide panoramic effect.Type: GrantFiled: August 27, 2009Date of Patent: October 8, 2013Assignee: CSR Technology Inc.Inventors: Noam Levy, Meir Tzur

Publication number: 20100033553Abstract: A camera that provides for a panorama mode of operation that stitches together two or more images to create a single image with a wide format. In panorama mode, a live view of a scene is transformed from rectangular coordinates to cylindrical coordinates and displayed by the camera. Also, an overlap portion between the previous image and the next image to be captured is characterized. In real time, after the previous image is captured, the overlap portion of the previous image is also transformed from rectangular coordinates into cylindrical coordinates. Next, the camera displays an overlay of at least a portion of the overlap portion onto the live view of the next image to be captured. And this overlay can assist the user in aligning the live view of the next image to be captured with the overlap portion of the previously captured image.Type: ApplicationFiled: August 6, 2009Publication date: February 11, 2010Applicant: Zoran CorporationInventor: Noam Levy
