  • Publication number: 20170078637
    Abstract: The present disclosure relates to an image processing apparatus and a method capable of generating high-definition viewpoint interpolation images at high speed. A space reconstruction unit reconstructs a space in which viewpoint images are photographed according to each viewpoint image and each disparity (pixel shift amount) map and supplying reconstruction data of the space to an interpolation position setting unit. The interpolation position setting unit sets an interpolation position in the reconstructed space while changing (an inclination of) a beam and supplies interpolation target coordinates indicating the set interpolation position to a data search unit. The data search unit generates an interpolation image at any viewpoint by sampling RGB values at interpolation target coordinates supplied from the interpolation position setting unit and outputs the generated interpolation image to a subsequent stage.

  • Publication number: 20170046821
    Abstract: The present disclosure relates to an image processing device and method, which are capable of reproducing optical information processing of a lens. A viewpoint PSF calculating unit converts each disparity map into a map of a depth z. Then, the viewpoint PSF calculating unit obtains a viewpoint position on the basis of each viewpoint image, a map of each depth z, and a focus position, and generates PSF data of each viewpoint on the basis of the viewpoint position. Here, the PSF data is a point spread function, and an offset amount and an intensity coefficient of each viewpoint can be obtained on the basis of the PSF data of each viewpoint. The viewpoint PSF calculating unit supplies the obtained PSF data of each viewpoint (that is, the offset amount and the intensity coefficient) to a light collection processing unit.
