Patent number: 9325905Abstract: An apparatus and method of generating a zoomed image is disclosed. A particular method includes receiving an instruction to perform a zoom operation. Window information is sent to an image sensor based on the instruction. The window information corresponds to a portion of the image sensor. In addition, a request to reduce the pixel clock rate may be sent to the image sensor. The request may cause the image sensor to reduce the pixel clock rate such that a frame rate of image data captured by the image sensor is maintained. Cropped image data corresponding to the portion of the image sensor is received. The cropped image data is upscaled to generate a zoomed image.Type: GrantFiled: March 17, 2014Date of Patent: April 26, 2016Assignee: QUALCOMM IncorporatedInventor: Ying X. Noyes

Publication number: 20140354859Abstract: Certain embodiments relate to banding detection and correction techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes banding correction techniques that cycle between detection of rolling banding and static banding to determine the power line frequency of ambient light, for example 50 Hz or 60 Hz. The banding correction techniques may also compare different image frames to detect rolling banding. The banding correction techniques may compare row sum data of a plurality of image frames and apply a Fourier analysis to determine a periodic signal of static banding at a particular ambient light power line frequency.Type: ApplicationFiled: September 12, 2013Publication date: December 4, 2014Applicant: QUALCOMM IncorporatedInventors: Ying X.

Patent number: 8837576Abstract: This disclosure describes techniques for improving functionalities of a back-end device, e.g., a video encoder, using parameters detected by a front-end device, e.g., a video camera. The techniques may involve detecting a scene change in a captured frame, based on one or more parameters of auto exposure (AE), auto white balance (AWB), and auto focus (AF) functions. If a scene change is detected in a captured frame, a video processing device, which may be a stand-alone device, or may be integrated into one of the front-end or back-end devices, provides an indication of the scene change. The video encoder interprets the signal as a trigger to encode the frame indicated as the frame where a scene change occurred as a reference I frame.Type: GrantFiled: May 5, 2010Date of Patent: September 16, 2014Assignee: QUALCOMM IncorporatedInventors: Liang Liang, Szepo R. Hung, Ruben M. Velarde, Ying X. Noyes, Haiyin Wang

Patent number: 8773577Abstract: An example image capture device determines a region of interest using a first image captured while a light source is powered off and a second image captured while a light source is powered on and uses the region of interest to automatically set configurations. In one example, an image capture device includes a controlled light source, an image sensor configured to capture images, and a processing unit configured to cause the image sensor to capture a first image of a scene while the controlled light source is powered off, cause the image sensor to capture a second image of the scene while the controlled light source is powered on, calculate luminance differences between a plurality of regions in the first image and a plurality of collocated regions in the second image, and determine that a region of interest includes those regions for which the luminance differences exceed a threshold.Type: GrantFiled: October 27, 2010Date of Patent: July 8, 2014Assignee: QUALCOMM IncorporatedInventors: Ruben M. Velarde, Thomas W. Osborne, Szepo Robert Hung, Haiyin Wang, Liang Liang, Ying X Noyes, Edward G. Atrero

Patent number: 8379130Abstract: An apparatus and method of processing images is disclosed. In a particular embodiment, the method includes receiving a selection of a first image from a plurality of images stored at a memory device and displaying the first image. The method also includes receiving image modification data to modify processing of the first image displayed and providing an adjusted value of an image processing parameter to an image processor. The adjusted value of the image processing parameter is determined based at least in part on the image modification data.Type: GrantFiled: August 7, 2009Date of Patent: February 19, 2013Assignee: QUALCOMM IncorporatedInventors: Babak Forutanpour, David L. Bednar, Ying X. Noyes, Szepo R. Hung
