Publication number: 20180270419Abstract: In various embodiments a camera with multiple optical chains, e.g., camera modules, is controlled to operate in one of a variety of supported modes of operation. The modes include a non-motion mode, a motion mode, a normal burst mode and/or a reduced data burst mode. Motion mode is well suited for capturing an image including motion, e.g., moving object(s) with some modules being used to capture scene areas using a shorter exposure time than other modules and the captured images then being combined taking into consideration locations of motion. A reduced data burst mode is supported in some embodiments in which camera modules with different focal lengths capture images at different rates. While the camera modules of different focal length operate at different image capture rates in the reduced data burst mode, images are combined to support a desired composite image output rate, e.g., a desired frame rate.Type: ApplicationFiled: March 6, 2018Publication date: September 20, 2018Inventors: Rajiv Laroia, Nitesh Shroff, Sapna A.

Patent number: 9998638Abstract: A camera device with a sensor which is mounted at an angle relative to a mounting surface or other reference surface is described. Camera modules, which include mirrors for light redirection, which are mounted at different angles in the camera device have sensors with different amounts of rotation. In some embodiments modules without mirrors use camera modules without rotated sensors while camera modules with mirrors may or may not use sensors which are rotated depending on the angle at which the modules are mounted in the camera device. By rotating the sensors of some camera modules rotation that maybe introduced by the angle at which a camera module is mounted can be offset. The images captured by different camera modules are combined in some embodiments without the need for computationally rotating an image thanks to the rotation of the sensor in the camera module used to capture the image.Type: GrantFiled: December 21, 2015Date of Patent: June 12, 2018Assignee: Light Labs Inc.Inventors: Rajiv Laroia, Sapna A Shroff

Patent number: 9979878Abstract: Zoom and focus control user interface methods and apparatus are described. Acceleration is monitored and interpreted to detect camera motion. Acceleration indicative of camera motion in a forward or backward direction is used to control zoom in or zoom out operations when a zoom function is enabled. The zoom function can be enabled by touching a touch sensor or pressing a button. Thus, by activating the zoom function and making intuitive movements forward or backward which can be detected through the use of sensors, a user can control zoom in and zoom out operations in an intuitive manner with little risk of shaking the camera or interfering with image capture that might occur if a touch display or other zoom control was used to control zoom operation while capturing one or more images. The zoom control function is well suited for use with still cameras and video cameras.Type: GrantFiled: February 20, 2015Date of Patent: May 22, 2018Assignee: Light Labs Inc.Inventors: Rajiv Laroia, Sapna A Shroff

Patent number: 9967535Abstract: Various features relating to reducing and/or eliminating noise from images are described. In some embodiments depth based denoising is used on images captured by one or more camera modules based on depth information of a scene area and optical characteristics of the one or more camera modules used to captures the images. In some embodiments by taking into consideration the camera module optics and the depth of the object included in the image portion, a maximum expected frequency can be determined and the image portion is then filtered to reduce or remove frequencies above the maximum expected frequency. In this way noise can be reduced or eliminated from image portions captured by one or more camera modules. The optical characteristic of different camera modules may be different. In some embodiments a maximum expected frequency is determined on a per camera module and depth basis.Type: GrantFiled: September 18, 2015Date of Patent: May 8, 2018Assignee: Light Labs Inc.Inventors: Rajiv Laroia, Nitesh Shroff, Sapna A Shroff

Patent number: 9948858Abstract: Methods and apparatus for processing images captured by a camera device including multiple optical chains, e.g., camera modules, are described. Three, 4, 5 or more optical chains maybe used. Different optical chains capture different images due to different perspectives. Multiple images, e.g., corresponding to different perspectives, are captured during a time period and are combined to generate a composite image. In some embodiments one of the captured images or a synthesized image is used as a reference image during composite image generation. The image used as the reference image is selected to keep the perspective of sequentially generated composite images consistent despite unintentional came movement and/or in accordance with an expected path of travel. Thus, which camera module provides the reference image may vary over time taking into consideration unintended camera movement. Composite image generation may be performed external to the camera device or in the camera device.Type: GrantFiled: August 22, 2016Date of Patent: April 17, 2018Assignee: Light Labs Inc.Inventors: Rajiv Laroia, Sapna A Shroff
