  • Patent number: 10841480
    Abstract: An imaging device includes an image sensor and a controller. The controller sets a focus detection area and a motion detection area, determines an instability of a subject for a motion based on an imaging signal corresponding to an inside of the motion detection area, determines a degree of focusing based on the imaging signal corresponding to an inside of the focus detection area. The controller makes an operation parameter of a focus adjustment operation different, when the subject is determined to be unstable once and then determined to be stable. The controller determines the degree of focusing by a focus adjustment operation using minute driving. The operation parameter is an amplitude or an amount of a movement of the focus lens.

  • Patent number: 10805528
    Abstract: An image data generating block 72 of an image capturing apparatus 12 generates polarized images having two or more resolutions from luminance of polarization in two or more directions acquired by a luminance data acquiring block 70. A pixel value converting block 74 generates new image data with a predetermined parameter being a pixel value on the basis of the polarized luminance in two or more directions. A transmission image generating block 76 connects image data of two or more types on a predetermined pixel line basis and then crops the requested data, thereby stream-transferring the cropped data from a communication block 78. A target object recognizing block 80 of an information processing apparatus 10 recognizes the state of a target object by use of the transmitted data and an output data generating block 82 generates output data by use of the recognized state.

  • Patent number: 10785412
    Abstract: An image capturing apparatus includes a sensor controller and a distance calculator. The sensor controller acquires a target image and a first reference image. The point spread function (PSF) of the target image is point-asymmetric, and the PSF of the first reference image being point-symmetric. The image sensor receives light having passed through a filter region that changes PSFs for sensor images of at least one kind into point-asymmetric forms, and then generates the target image for which a PSF has been changed into a point-asymmetric form by the filter region, and the first reference image that is not the target image. The distance calculator calculates the distance to an object captured in the target image and the first reference image, in accordance with the correlations each between an image obtained by convoluting a blur kernel to the target images and the first reference image.

  • Patent number: 10652490
    Abstract: The invention relates to a method for detecting bad pixels from a pixel array of a device, for capturing an image, that is sensitive to infrared radiation. The method includes: receiving an input image captured by the pixel system, and calculating a score for a plurality of target pixels including at least some of the pixels from the input image. The score for each target pixel is generated on the basis of k pixels of the input image that are selected in a window of H by H pixels around the target pixel. H is an odd integer greater than or equal to 3, and k is an integer between 2 and 5. Each pixel, from the set formed of the k pixels and the target pixel, share at least one border or corner with another pixel from said set, and the values of the k pixels are at respective distances from the value of the target pixel, the k pixels being selected on the basis of the k distances. The method also includes detecting that at least one of the target pixels is a bad pixel on the basis of the calculated scores.

  • Patent number: 10634559
    Abstract: A spectrally-scanned hyperspectral EO sensor trades the temporal properties of spectral information content for instantaneous situation awareness by capturing an image frame and scanning the spectral scene (wavelength) to build up spectral content. The objective optical system, preferably including a chromatic aberration enhancing device, separates spectral components of the incident radiation. A focus cell is used to adjust a relative axial focus position of the objective optical system with respect to a detector to at least two different axial focus positions to adjust the image position and read out an image frame for a spectrally-weighted component. A processor computes a relative spatial image contrast from a plurality of image frames at different wavelengths as a function of encoded focus cell position. A mechanism may be configured to move the enhancing device in and out of the optical path to form a dual gray-scale and hyperspectral EO sensor.
