Patent number: 8953058Abstract: A 9 pixel-by-9 pixel working window slides over an input Bayer image. For each such window, a demosaicing operation is performed. For each such window, corrective processing is performed relative to that window to produce relative differences for that window. For each such window for which relative differences have been produced, those relative differences are regulated. For each window, a maximum is found for that window's regulated relative differences; in one embodiment of the invention, this maximum is used to select which channel is sharp. For each window, the colors in that window are corrected based on the relative difference-based maximum found for that window. For each window, edge oversharpening is softened in order to avoid artifacts in the output image. The result is an output image in which axial chromatic aberrations have been corrected.Type: GrantFiled: June 29, 2011Date of Patent: February 10, 2015Assignee: Fotonation LimitedInventors: Eyal Ben-Eliezer, Tomer Schwartz, Ehpraim Goldenberg, Noy Cohen

Patent number: 8723912Abstract: Different distances of two or more objects in a scene being captured in a video conference are determined based on applying a face model to a detected face within a digitally-acquired image. At least one portion of the scene other than the face is identified as comprising a background object that is a different distance from the video camera component than the face. The technique involves blurring or otherwise rendering unclear the background object.Type: GrantFiled: September 16, 2010Date of Patent: May 13, 2014Assignee: DigitalOptics Corporation Europe LimitedInventors: Guy Michrowski, Gal Shabtay, Noy Cohen, Eyal Ben-Eliezer, Ephraim Goldenberg

Patent number: 8576323Abstract: A method for designing a mask, the method includes: choosing or receiving a desired contrast value; and determining sizes, locations and shapes of multiple rotationally symmetric regions of a mask such as to define a modulation transfer function that is characterized by a substantially uniform response over a spatial frequency range; wherein the uniform response is substantially indifferent to an orientation of features of the object and to a location of the object within a deep depth-of-field region. An optical imaging system that includes: a mask that includes multiple rotationally regions; wherein the multiple rotationally symmetric regions are shaped and positioned such as to define a modulation transfer function that is characterized by a substantially uniform response over a spatial frequency range, wherein the uniform response is substantially indifferent to an orientation of features of the object and to a location of the object within a deep depth-of-field region.Type: GrantFiled: October 19, 2009Date of Patent: November 5, 2013Assignee: RAMOT at Tel Aviv University Ltd.Inventors: Emanuel Marom, Eyal Ben-Eliezer, Naim Konforti, Benjamin Milgrom

Patent number: 8488031Abstract: A chromatic noise reduction method is provided for removing chromatic noise from the pixels of a mosaic image. In one implementation, an actual chroma value and a de-noised chroma value are derived for the central pixel of a matrix of pixels. Based at least in part upon these chroma values, a final chroma value is derived for the central pixel. The final chroma value is then used, along with the actual luminance of the central pixel, to derive a final de-noised pixel value for the central pixel. By de-noising the central pixel based on its chroma (which takes into account more than one color) rather than on just the color channel of the central pixel, this method allows the central pixel to be de-noised in a more color-coordinated fashion. As a result, improved chromatic noise reduction is achieved.Type: GrantFiled: January 14, 2011Date of Patent: July 16, 2013Assignee: DigitalOptics Corporation Europe LimitedInventors: Tomer Schwartz, Eyal Ben-Eliezer, Orly Liba, Noy Cohen

Patent number: 8363085Abstract: Different distances of two or more objects in a scene being captured in a video conference are determined using an auto-focus sweep of the scene. A depth map of the scene is generated based on the auto-focus sweep. At least one of the objects is identified as a foreground object or a background object, or one or more of each, based on the determining of the different distances. The technique involves blurring or otherwise rendering unclear at least one background object or one or more portions of the scene other than the at least one foreground object, or combinations thereof, also based on the determining of distances.Type: GrantFiled: September 16, 2010Date of Patent: January 29, 2013Assignee: DigitalOptics Corporation Europe LimitedInventors: Guy Michrowski, Gal Shabtay, Noy Cohen, Eyal Ben-Eliezer, Ephraim Goldenberg

Publication number: 20060204861Abstract: A mask for enhancing the depth of focus of an optical imaging system is designed by optimizing an optical property (transmittance or reflectance) of the mask relative to the intensity distribution in the system's image plane. Preferably, a desired PSF intensity is selected, a desired misfocus parameter range is selected, and the optical property is adjusted to minimize a measure of the departure of the system's PSF intensity, as computed from the mask's optical property, from the desired PSF intensity, over the entire misfocus parameter range. Most preferably, the desired PSF intensity is selected as the inverse Fourier transform of a desired OTF. Preferably, the mask is fabricated as a DOE.Type: ApplicationFiled: March 14, 2005Publication date: September 14, 2006Inventors: Eyal Ben-Eliezer, Emanuel Marom, Naim Konforti, Zeev Zalevsky
