Patent number: 8687087Abstract: A parameter of a digital camera or other digital image acquisition device is adjusted to maintain the resulting digital signal within a range carried by a digital processing path that carries a limited number of bits. The magnitude of the parameter is then also used to represent the image. Examples of the parameter include analog signal gain and exposure time. This is a cost effective way to increase the dynamic range of a digital camera, instead of increasing the width of its digital processing path. The digital data may be processed to obtain either tone mapped images, which are compatible with current cameras and other equipment, or to obtain images with a greater dynamic range for use with suitable displays and the like.Type: GrantFiled: June 1, 2007Date of Patent: April 1, 2014Assignee: CSR Technology Inc.Inventors: Shimon Pertsel, Ohad Meitav, Eli Pozniansky, Erez Galil

Patent number: 8447132Abstract: Disclosed are method and a corresponding apparatus, where the method according to one embodiment includes making a determination that a first portion of digital image data represents a physical object of a predetermined type, determining an amount of a parameter, such as a gain, to apply to the first portion of the digital image data, based on the determination that the first portion of the digital image data represents a physical object of the predetermined type, and applying the determined amount of the parameter to the first portion of the digital image data. The method may be part of a dynamic range correction operation.Type: GrantFiled: December 6, 2010Date of Patent: May 21, 2013Assignee: CSR Technology, Inc.Inventor: Erez Galil

Patent number: 8218037Abstract: Techniques for modifying data of an image that can be implemented in a digital camera, video image capturing device and other optical systems are provided to correct for Image image shading variations appearing in data from a two-dimensional photo-sensor. These variations can be caused by imperfect lenses, non-uniform sensitivity across the photo-sensor, and internal reflections within a housing of the optical system, for example. In order to correct for these variations, a small amount of modification data is stored in a small memory within the camera or other optical system, preferably separate correction data for each primary color. Image data from individual pixels are corrected on the fly by interpolating individual pixel corrections from the stored modification data, at the same rate as the image data is being acquired, so that the correction takes place without slowing down data transfer of picture data from the image sensor.Type: GrantFiled: October 12, 2010Date of Patent: July 10, 2012Assignee: CSR Technology Inc.Inventors: Victor Pinto, Erez Galil

Publication number: 20120120197Abstract: A system, method, and computer program product for providing pseudo 3D user interface effects in a digital camera with existing lens distortion correction hardware. A distortion map normally used to correct captured images instead alters a displayed user interface object image to support production of a “pseudo 3D” version of the object image via production of at least one modified image. A blending map also selectively mixes the modified image with a second image to produce a distorted blended image. A set or series of such images may be produced automatically or at user direction to generate static or animated effects in-camera without a graphics accelerator, resulting in hardware cost savings and extended battery life.Type: ApplicationFiled: May 11, 2011Publication date: May 17, 2012Applicant: ZORAN CORPORATIONInventors: Dmitry RYUMA, Daniel Fishkov, Erez Galil, Shimon Pertsel, Chang Liu

Patent number: 7907195Abstract: A technique for modifying data of an image, such as can be implemented in a still camera or video recorder in order to correct for defects in its optical and/or electronic systems, includes generating data to modify the image as a function of radial position across it. A variation of the intensity across an image (lens shading) that appears in data from a two-dimensional detector is an example of an application of the technique. In order to make modifications to the data, positions of a two-dimensional raster scan pattern of an image sensor are converted to radial positions and this is then used to generate the modification data. The modification data is generated on the fly, at the same rate as the image data is being acquired, so that the modification takes place without slowing down data transfer from the image sensor.Type: GrantFiled: July 18, 2008Date of Patent: March 15, 2011Assignee: Zoran CorporationInventors: Victor Pinto, Erez Galil
