  • Patent number: 9686478
    Abstract: Systems and methods are provided for generating high-dynamic range images. In particular, a signal-to-noise (SNR) ratio objective associated with an imaging platform configured to capture one or more images of a region of interest using an image sensor having a first portion and a second portion can be determined. The SNR objective can specify a desired SNR response as a function of a brightness of the region of interest. A first integration time and a second integration time can then be determined based at least in part on the SNR objective. Data indicative of a plurality of image frames can then be obtained. Each image frame is captured by exposing the first portion of the image sensor for the first integration time and exposing the second portion of the image sensor for the second integration time.

  • Patent number: 9684225
    Abstract: A controller controls a focus lens driver so as to maintain an in-focus state associated with a magnification variation, based on information on a tracking curve that represents a position of the focus lens corresponding to an object distance and a focal length of an image-pickup optical system. The controller controls the focus lens driver so as to prevent the focus lens from being moved for focusing based on a difference between an actual position of the focus lens and the position of the focus lens indicated by the tracking curve in a case the focus lens driver is driving the focus lens based on information on the tracking curve.

  • Patent number: 9678303
    Abstract: Provided are an imaging device and a focusing control method capable of preventing a focusing error even in a case where still image capturing is consecutively performed to enhance imaging quality. A digital camera performs a correlation operation of two images captured by a pixel pair P1 after performing an imaging process of an N-th frame, and determines a reliability of a correlation operation result based on the result of the correlation operation. In a case where the reliability is low, the digital camera performs a focusing control based on a contrast AF method in each time of imaging subsequent to an (N+1)-th frame, and in a case where the reliability is low, the digital camera performs a focusing control based on a phase difference AF method in an imaging process of the (N+1)-th frame.

  • Patent number: 9661308
    Abstract: Using the same image sensor to capture a two-dimensional (2D) image and three-dimensional (3D) depth measurements for a 3D object. A laser point-scans the surface of the object with light spots, which are detected by a pixel array in the image sensor to generate the 3D depth profile of the object using triangulation. Each row of pixels in the pixel array forms an epipolar line of the corresponding laser scan line. Timestamping provides a correspondence between the pixel location of a captured light spot and the respective scan angle of the laser to remove any ambiguity in triangulation. An Analog-to-Digital Converter (ADC) in the image sensor operates as a Time-to-Digital Converter (TDC) to generate timestamps. When the epipolar line is misaligned or curved, multiple TDC arrays acquire timestamps of multiple pixels (in multiple rows) substantially simultaneously. Multiple timestamp values are reconciled to obtain a single timestamp value for a light spot.

  • Patent number: 9654752
    Abstract: A new framework for video compressed sensing models the evolution of the image frames of a video sequence as a linear dynamical system (LDS). This reduces the video recovery problem to first estimating the model parameters of the LDS from compressive measurements, from which the image frames are then reconstructed. We exploit the low-dimensional dynamic parameters (state sequence) and high-dimensional static parameters (observation matrix) of the LDS to devise a novel compressive measurement strategy that measures only the dynamic part of the scene at each instant and accumulates measurements over time to estimate the static parameters. This enables us to lower the compressive measurement rate considerably yet obtain video recovery at a high frame rate that is in fact inversely proportional to the length of the video sequence. This property makes our framework well-suited for high-speed video capture and other applications.
