Text blocks in the object images are identified based on predetermined location information of the identified object. Interim sets of characters in the identified text blocks are generated based on format information of the identified object. Based on the interim sets of characters, a set of characters in the text block in the object is determined.Type: GrantFiled: February 7, 2012Date of Patent: August 16, 2016Assignee: QUALCOMM IncorporatedInventors: Hyung-Il Koo, Kisun You, Hyun-Mook Cho

Patent number: 9395065Abstract: A device for manipulating an emission characteristic of a light-emitting diode includes an optical element configured to be movably arranged between a first position and at least one additional position relative to the light-emitting diode. The optical element is configured to bring about a first light distribution of the light emitted by the light-emitting diode if the optical element is arranged in the first position. The optical element is further configured to bring about a further light distribution of the light emitted by the light-emitting diode if the optical element is arranged in the at least one additional position. The device further includes at least one micromechanical actuator configured to move the optical elements between the first and the at least one additional position in order to manipulate the emission characteristic.Type: GrantFiled: February 15, 2012Date of Patent: July 19, 2016Assignee: Robert Bosch GmbHInventor: Andreas Krauss

Patent number: 9392176Abstract: An image capture apparatus has an image sensor and an optical anti-shake mechanism that reduces a shake of a captured image by driving an optical correction element in a different direction from an optical axis of an imaging optical system in accordance with a detected shake. Reference coordinates for geometric deformation processing applied to the captured image are determined based on an amount and direction of a movement of the optical correction element. The geometric deformation processing is applied to the captured image using these reference coordinates and an amount of geometric deformation based on the detected shake. Coordinates of the captured image corresponding to an intersection of the optical axis and the image sensor after the optical correction element is moved through the driving are determined as the reference coordinates.Type: GrantFiled: July 11, 2014Date of Patent: July 12, 2016Assignee: Canon Kabushiki KaishaInventor: Hidetoshi Tsubaki

Patent number: 9386217Abstract: An image capturing apparatus having an image sensor including focus detection pixels capable of outputting a pair of image signals for focus detection determines whether each line of the pixels of the image sensor is an addition/non-addition line that outputs the image signal suitable/unsuitable for detection of a correlation amount, obtains the correlation amount for each addition line based on the pair of image signals, add the obtained correlation amount of the addition line, counts the number of addition lines, obtains a defocus amount based on the added correlation amount, and drives a focus lens based on the defocus amount when a product of an evaluation value representing reliability of the defocus amount and a predetermined standard number of additions is smaller than the product of the number of addition lines and a standard evaluation value representing a predetermined evaluation value.Type: GrantFiled: July 10, 2015Date of Patent: July 5, 2016Assignee: Canon Kabushiki KaishaInventor: Koichi Fukuda

Patent number: 9357136Abstract: A first image frame is gathered. The first image frame, a first white balance value, and a first exposure value are stored. Information is sensed from an inertial sensor. A second image frame and intermediate image frames are gathered. A distance traversed by a camera is determined. In response to one or more of: the distance exceeding a predetermined threshold, or a new white balance value significantly differing from a previous white balance value, or a new exposure value significantly differing from a previous exposure value, a second white balance value and a second exposure value are determined for the second image frame. A smoothed white balance value and a smoothed exposure value are determined for the intermediate image frames.Type: GrantFiled: February 4, 2014Date of Patent: May 31, 2016Assignee: Nokia Technologies OyInventors: Maneli Noorkami, Daniel A.

Patent number: 9357130Abstract: Techniques are disclosed for selectively capturing, retaining, and combining multiple sub-exposure images or brackets to yield a final image having diminished motion-induced blur and good noise characteristics. More specifically, after or during the capture of N brackets, the M best may be identified for combining into a single output image, (N>M). As used here, the term “best” means those brackets that exhibit the least amount of relative motion with respect to one another—with one caveat: integer pixel shifts may be preferred over sub-pixel shifts.Type: GrantFiled: June 4, 2013Date of Patent: May 31, 2016Assignee: Apple Inc.Inventors: Todd Sachs, Marius Tico, Rolf Toft, Paul Hubel, George Williams

Patent number: 9344639Abstract: In embodiments, a camera device includes HDR monochromatic image sensors that capture an image as an HDR clear image in monochrome, and the camera device includes HDR color image sensors that capture the image as a Bayer image. The HDR monochromatic image sensors may be implemented as interlaced pixel lines having alternating higher exposure times and lower exposure times, or may be implemented as a checkerboard pixel pattern with white pixels of the checkerboard pixel pattern having an exposure duration and black pixels of the checkerboard pixel pattern having a different exposure duration. The camera device implements image processing algorithms that demosaic the Bayer image to generate an initial color image, and demosaic the HDR clear image to generate a clear image. An image fusion application then produces an enhanced, high-resolution HDR color image based on the initial color image and the clear image.Type: GrantFiled: August 12, 2014Date of Patent: May 17, 2016Assignee: Google Technology Holdings LLCInventors: Yuriy Musatenko, Adrian M Proca
