  • Patent number: 11770940
    Abstract: In an imaging element 28, a first light detecting layer 12 includes an organic photoelectric conversion film 38 that detects light of a predetermined wavelength band and carries out photoelectric conversion, and photoelectrically converts incident light on the imaging element and light reflected from a wire grid polarizer layer 14. The wire grid polarizer layer 14 includes polarizers 48 in which linear materials that do not allow transmission of light therethrough are arranged at intervals shorter than the wavelength of the incident light. A second light detecting layer 16 includes photoelectric conversion elements 54 that photoelectrically convert light transmitted through the polarizers 48.

  • Patent number: 11710289
    Abstract: An information processing apparatus includes an imaging apparatus that irradiates reference light in a predetermined wavelength band to a subject and captures reflection of the reference light from the subject to acquire data of captured images including a polarized image in multiple bearings (S30). Based on the polarized image, the imaging apparatus acquires a polarization degree image representing a distribution of polarization degrees (S32). The imaging apparatus extracts a region whose polarization degree falls within a predetermined range of polarization degrees as an image of the subject having a predetermined material (S34). The imaging apparatus performs relevant processing on the subject image to generate output data and outputs the generated data (S36).

  • Patent number: 11216907
    Abstract: An image generating apparatus 10 acquires information associated with a motion of a head of a user wearing a head-mounted display 100. For a period of time for which the head is stopped, the image generating apparatus 10 generates a display image 70 with a standard resolution, and transmits the display image 70 to the head-mounted display 100, so that display images 71 having the same resolution are displayed. For a period of time for which the head is moved, the image generating apparatus 10 generates display images 72 each having the reduced resolution, and the head-mounted display 100 generates display images 73 obtained by enlarging the display images 72.

  • Patent number: 11196975
    Abstract: During a period when a user's dominant eye is the right eye, an image generating device (200) generates an image for the right eye (272) at a standard resolution and generates a display image for the left eye (270) at a lower resolution. During a period when the dominant eye is the left eye, the image generating device (200) generates an image for the left eye (278) at the standard resolution and generates a display image for the right eye (280) at a lower resolution. In a head mounted display (100), the images with the lower resolution are enlarged into display images (274) and (276), and the image for the left eye and the image for the right eye are displayed.

  • Patent number: 11182638
    Abstract: Data of a captured image including a polarized image is acquired (S10), and space information relating to a position and a posture of a subject in a real space and the position and the posture on an imaging plane is acquired using the captured image data (S12). Next, a polarization degree distribution is acquired from a polarized image of a plurality of orientations (S14), and a position of a light source is acquired by specifying an image of a true light source by threshold value determination of the polarization degree (S16). A reflection characteristic is acquired by applying a rendering equation under assumption that luminance of the captured image is already known (S18), and a material suitable therewith is specified as a material of the subject (S20). Processing according to the material is performed to generate output data and output the data (S22).

  • Patent number: 11173394
    Abstract: A captured image acquisition section 50 acquires from an imaging apparatus 12 data of a polarized image captured of a target object and stores the image data into an image data storage section 52. A region division section 58 in a normal line information acquisition section 54 divides a plane of the image into regions according to a predetermined criterion such as a polarization degree or luminance. A normal line calculation section 60 obtains a distribution of normal lines of each region by applying either a specular reflection model or a diffuse reflection model thereto. An integration section 62 integrates the distributions of normal lines of the regions into a normal line distribution of the entire image. An output data generation section 56 performs information processing using the normal line distribution and outputs the result of the processing.

  • Patent number: 11048912
    Abstract: A captured image acquisition section 50 acquires, from an imaging apparatus 12, data of a polarized image obtained by capturing a target object and stores the data into an image data storage section 52. A region extraction section 60 of a target object recognition section 54 extracts a region in which a figure of the target object is included in the polarized image. A normal line distribution acquisition section 62 acquires a distribution of normal line vectors on a target object surface in regard to the extracted region. A model adjustment section 66 adjusts a three-dimensional model of the target object stored in a model data storage section 64 in a virtual three-dimensional space such that the three-dimensional model conforms to the distribution of the normal line vectors acquired from the polarized image to specify a state of the target object.

  • Patent number: 11010901
    Abstract: A captured image acquisition section 50 acquires, from an imaging apparatus 12, data of a polarized image obtained by capturing a target object and stores the data into an image data storage section 52. A normal line distribution acquisition section 362 of a region segmentation section 310 acquires a distribution of normal line vectors of a subject surface using the polarized image. A region decision section 312 evaluates the distribution of normal line vectors with a predetermined criterion indicating stability such as a dispersion and determines a region in which the stability is high as a region of a figure of a subject to segment the image. An output data generation section 56 carries out various processes using a result of the segmentation to generate output data.

  • 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.
