  • Patent number: 10965931
    Abstract: Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

  • Patent number: 10757342
    Abstract: An auto exposure method for an image capture device includes the steps of gathering ambient light data using an ambient light sensor of the image capture device, selecting a frame rate corresponding to the gathered ambient light data, and determining an optimal image capture frame rate for the image capture device. The auto exposure method determines the optimal image capture frame rate by executing an auto exposure algorithm with a processor using the selected frame rate as an initialization parameter for the auto exposure algorithm.

  • Patent number: 10349037
    Abstract: The present disclosure describes structured-stereo imaging assemblies including separate imagers for different wavelengths. The imaging assembly can include, for example, multiple imager sub-arrays, each of which includes a first imager to sense light of a first wavelength or range of wavelengths and a second imager to sense light of a different second wavelength or range of wavelengths. Images acquired from the imagers can be processed to obtain depth information and/or improved accuracy. Various techniques are described that can facilitate determining whether any of the imagers or sub-arrays are misaligned.

  • Publication number: 20180213201
    Abstract: Providing a disparity map includes acquiring first and second stereo images, binarizing the first stereo image to obtain a binarized image, and applying a block matching technique to the first and second stereo images to obtain an initial disparity map in which individual image elements are assigned a respective initial disparity value. For each respective image element, an updated disparity value that represents a product of the initial disparity value assigned to the image element and a value associated with the image element in the binarized image is obtained. An updated disparity map can be generated and represents the updated disparity values of the image elements.

  • Publication number: 20120120197
    Abstract: A system, method, and computer program product for providing pseudo 3D user interface effects in a digital camera with existing lens distortion correction hardware. A distortion map normally used to correct captured images instead alters a displayed user interface object image to support production of a “pseudo 3D” version of the object image via production of at least one modified image. A blending map also selectively mixes the modified image with a second image to produce a distorted blended image. A set or series of such images may be produced automatically or at user direction to generate static or animated effects in-camera without a graphics accelerator, resulting in hardware cost savings and extended battery life.
