Publication number: 20240064417Abstract: Imaging systems and techniques are described. For example, an imaging system may receive raw image data captured using an image sensor. The imaging system may process the raw image data according to a first image signal processor (ISP) setting to generate a first image and process the raw image data according to a second ISP setting (that is distinct from the first ISP setting) to generate a second image. The imaging system may output the first image and the second image.Type: ApplicationFiled: August 22, 2022Publication date: February 22, 2024Inventors: Rohan DESAI, Masood QAZI, Krishnam INDUKURI, Vinod Kumar NAHVAL, Rajakumar GOVINDARAM

Patent number: 11330204Abstract: Examples are described of automatic exposure timing synchronization. An imaging system includes a first image sensor configured to capture a first image according to a first exposure timing, including by exposing first region of interest (ROI) image data at the first image sensor for a first ROI exposure time period. Based on the first exposure timing, the imaging system sets a second exposure timing for a second image sensor to capture a second image. Capture of the second image according to the second exposure timing includes exposure of second ROI image data at the second image sensor for a second ROI exposure time period. The second exposure timing may be set so that the start of the second ROI exposure time period aligns with the start of the first ROI exposure time period, and/or so that the first and second ROI exposure time periods overlap.Type: GrantFiled: May 17, 2021Date of Patent: May 10, 2022Assignee: QUALCOMM IncorporatedInventors: Jeyaprakash Soundrapandian, Ramesh Ramaswamy, Sureshnaidu Laveti, Rajakumar Govindaram

The method may include launching a configurable actuator driver and identifying a particular type of lens actuator that resides on the mobile device. Based upon the particular type of lens actuator that resides on the mobile device, lens-actuator-specific parameter values are obtained that facilitate control interfacing with the particular type of lens actuator. In addition, tuning parameter values are obtained that characterize a displacement-response of the particular type of actuator to control signal values, and the tuning parameter values for the particular type of lens actuator are provided to a configurable lens-actuator driver. The particular type of lens actuator that resides on the mobile computing device is then operated using the tuning parameter values.Type: GrantFiled: July 30, 2013Date of Patent: October 27, 2015Assignee: Qualcomm Innovation Center, Inc.Inventors: Haibo Zhong, Hau Ling Hung, Jeyaprakash Soundrapandian, Rajakumar Govindaram, Sreesudhan Ramakrish Ramkumar
