  • Patent number: 11333885
    Abstract: A light diffusion member constituting a head-up display device includes multiple micro-lenses and has a curved base surface. The edge angle is larger than the base surface angle change amount. The edge angle is an angle formed by one of tangent lines of two micro-lenses and the other of the tangent lines passing through a boundary between two adjacent micro-lenses on a cross section orthogonal to the base surface. A reference line has a constant direction on the cross section, and a normal line passes at an arbitrary position on the base surface. The maximum value is ?max and the minimum value is ?min among angles between the normal line and the reference line. The base surface angle change amount is the absolute value of the difference between ?max and ?min.

  • Patent number: 11216962
    Abstract: Some embodiments are directed to an integrated circuit and computer-implemented method for estimating a depth map from an image using a joint bilateral filter at reduced computational complexity. For that purpose, image data of an image is accessed as well as depth data of a template depth map. A joint bilateral filter is then applied to the template depth map using the image data as a range term in the joint bilateral filter, thereby obtaining an image-adapted depth map as output. The applying of the joint bilateral filter includes initializing a sum-of-weighted-depths volume and a sum-of-weights volume as respective empty data structures in a memory, performing a splatting operation to fill said volumes, performing a slicing operation to obtain an image-adapted depth volume, and performing an interpolation operation to obtain an image-adapted depth value of the image-adapted depth map for each pixel in the image.

  • Patent number: 10643889
    Abstract: A method of improving selectivity of a metal in a selective deposition process. A pre-treatment process for the metal modifies the metal surface, and includes first reducing the metal to remove organic contamination from the metal followed by oxidation of the metal to allow a monolayer of a metal oxide to grow on the surface. This modification of the metal allows inhibitor molecules to adsorb on the metal oxide monolayer to improve selectivity.
