  • Publication number: 20210374906
    Abstract: A normal candidate information generation unit 31 of an information processor 30 generates normal candidate information for each pixel indicating, for example, a zenith angle, or an azimuth angle, or a zenith angle and an azimuth angle, on the basis of a polarization image in a plurality of polarization directions obtained by a polarization imaging unit 20. The in-plane pixel selection unit 32 selects a plurality of pixels indicating the plane to be observed in the polarization image. A normal calculation unit 33 calculates a normal of the plane to be observed on the basis of the normal candidate information of the pixels selected by the in-plane pixel selection unit 32.

  • Publication number: 20210243437
    Abstract: A polarization imaging unit 20 acquires a polarized image including polarization pixels with a plurality of polarization directions. An information compression unit 40 sets reference image information based on polarized image information of reference polarization pixels with at least a plurality of polarization directions in the polarized image and generates difference information between the polarized image information of each of polarization pixels different from the reference polarization pixels in the polarized image and the reference image information. In addition, the information compression unit 40 reduces the amount of information of the difference information generated for each of the polarization pixels with the plurality of polarization directions to generate compressed image information including the reference image information and the difference information with the reduced amount of information.

  • Patent number: 11044419
    Abstract: [Object] To reproduce an image to which an effect desired by a user is added. [Solution] There is provided an image processing device including: an image reverse stabilization processing unit configured to add an effect of expressing shaking to an image on the basis of shaking information on shaking of the image. In addition, there is provided an image processing device including: an image reverse stabilization processing unit configured to decide a degree of an effect of expressing shaking to be added to an image, on the basis of an expectation value of an immersed feeling of an observer with respect to the image.

  • Publication number: 20210152748
    Abstract: A polarization imaging unit 20 acquires a polarization image using a lens. In a parameter storage unit 32 of an information processing unit 30, parameters related to a change in polarization state due to the lens which are estimated in advance from polarization state information acquired by imaging a light source in a predetermined polarization state using the lens and polarization state information indicating the polarization state of the light source, for example, change parameters indicating the change in polarization state due to the lens or correction parameters for correcting the change in polarization state due to the lens are stored. A polarization state correction unit 33 of the information processing unit 30 corrects the change in polarization state due to the lens, using the parameters stored in advance in the parameter storage unit 32.

  • Patent number: 10798284
    Abstract: The present disclosure relates to an image processing apparatus and method that enables to correctly obtain an area of a main object at the time of auto focusing. A control block selects a local focus area from information of a taken image and supplies designated focus position information indicative of the selected local focus area to an image processing block. The image processing block executes a control operation related with focusing on the basis of object area information indicative of an area corresponding to two or more objects within an image and designated focus position information indicative of a designated focus position in this image. The present disclosure is applicable to an imaging apparatus, for example.
