Patent number: 10992873Abstract: Systems, methods, and computer-readable media are provided for transferring color information from a no-flash image of a scene to a flash image of the scene using a localized tonal mapping algorithm. In some aspects, an example method can include obtaining a no-flash image and a flash image, mapping color information from the no-flash image to the flash image, and generating an output image including the flash image modified based on the mapping to include at least a portion of the color information from the no-flash image.Type: GrantFiled: March 6, 2019Date of Patent: April 27, 2021Assignee: Qualcomm IncorporatedInventors: Reza Pourreza Shahri, Ramin Rezaiifar

Patent number: 10977802Abstract: Techniques and systems are provided for segmenting one or more frames. For example, incremental optical flow maps can be determined between adjacent frames of a plurality of frames. Using the incremental optical flow maps, a cumulative optical flow map can be determined between a first frame of the plurality of frames and a last frame of the plurality of frames. A segmentation mask can be determined using the first frame of the plurality of frames. Foreground pixels of the segmentation mask for the last frame of the plurality of frames can then be adjusted relative to corresponding foreground pixels for the first frame. The foreground pixels can be adjusted using the cumulative optical flow map between the first frame and the last frame of the plurality of frames.Type: GrantFiled: August 29, 2018Date of Patent: April 13, 2021Assignee: QUALCOMM IncorporatedInventors: Sunid Wilson, Ramin Rezaiifar

Patent number: 10818081Abstract: Techniques and systems are described herein for determining dynamic lighting for objects in images. Using such techniques and systems, a lighting condition of one or more captured images can be adjusted. Techniques and systems are also described herein for determining depth values for one or more objects in an image. In some cases, the depth values (and the lighting values) can be determined using only a single camera and a single image, in which case one or more depth sensors are not needed to produce the depth values.Type: GrantFiled: March 10, 2020Date of Patent: October 27, 2020Assignee: QUALCOMM IncorporatedInventors: Ramin Rezaiifar, Antwan Gaggi, Donna Roy

Patent number: 10362205Abstract: In general, techniques are described that facilitate processing of color image data using both a mono image data and a color image data. A device comprising a monochrome camera, a color camera and a processor may be configured to perform the techniques. The monochrome camera may be configured to capture monochrome image data of a scene. The color camera may be configured to capture color image data of the scene. The processor may be configured to perform intensity equalization with respect to a luma component of either the color image data or the monochrome image data to correct for differences in intensity between the color camera and the monochrome camera.Type: GrantFiled: September 19, 2016Date of Patent: July 23, 2019Assignee: QUALCOMM IncorporatedInventors: William Mantzel, Ramin Rezaiifar, Chiachi Sung

A device comprising a monochrome camera, a color camera, and a processor may be configured to perform the techniques. The monochrome camera may capture monochrome image data of a scene. The color camera may capture color image data of the scene. A processor may determine a parallax value indicative of a level of parallax between the monochrome image data and the color image data and determine that the parallax is greater than the parallax threshold. The processor may further combine, in response to the determination that the parallax is greater than the parallax threshold, a luma component of the color image data with a luma component of the monochrome image data to generate a luma component of enhanced color image data.Type: GrantFiled: September 19, 2016Date of Patent: July 2, 2019Assignee: QUALCOMM IncorporatedInventors: William Mantzel, Ramin Rezaiifar, Chiachi Sung

Patent number: 10290111Abstract: A method for compositing images by an electronic device is described. The method includes obtaining a first composite image that is based on a first image from a first lens with a first focal length and a second image from a second lens with a different second focal length. The method also includes downsampling the first composite image to produce a downsampled first composite image. The method further includes downsampling the first image to produce a downsampled first image. The method additionally includes producing a reduced detail blended image based on the downsampled first composite image and the downsampled first image. The method also includes producing an upsampled image based on the reduced detail blended image and the downsampled first composite image. The method further includes adding detail from the first composite image to the upsampled image to produce a second composite image.Type: GrantFiled: January 23, 2017Date of Patent: May 14, 2019Assignee: QUALCOMM IncorporatedInventors: Chao Jia, Ramin Rezaiifar

Patent number: 10251114Abstract: Local IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.Type: GrantFiled: August 25, 2014Date of Patent: April 2, 2019Assignee: QUALCOMM IncorporatedInventors: Peerapol Tinnakornsrisuphap, Fatih Ulupinar, John Nasielski, Jun Wang, Parag Agashe, Rajarshi Gupta, Ramin Rezaiifar

Patent number: 9955438Abstract: Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.Type: GrantFiled: September 26, 2006Date of Patent: April 24, 2018Assignee: QUALCOMM IncorporatedInventors: Donna Ghosh, Rashid Ahmed Akbar Attar, Christopher Gerard Lott, Ramin Rezaiifar, Juan Montojo
