Patent number: 9833972Abstract: In a laminated steel plate in which steel plates are joined to both faces of a core layer, the core layer is formed of a meshed wire group formed using wires in a mesh form and a resin sheet, the wires forming the meshed wire group have a tensile strength of 601 MPa or higher, and an opening of the meshed wire group is equal to or less than ten times the thickness of the steel plates. By thus defining the tensile strength of the wires, light-weightness can be achieved compatibly with high rigidity and shock resistance, and by defining the opening of the meshed wire group, workability and shape stability after being processed can be improved.Type: GrantFiled: July 28, 2010Date of Patent: December 5, 2017Assignee: NIPPON STEEL & SUMITOMO METAL CORPORATIONInventors: Hiroshi Ohishi, Atsuo Koga, Hirokazu Taniguchi, Hiroshi Ohashi

Patent number: 9799256Abstract: An image processing device includes a light detection unit and an image conversion unit. The light detection unit is configured to detect a first grayscale value of a background image. The background image is an image seen by a user through an at least partially transparent display panel. The image conversion unit is configured to generate a correction image having a second grayscale value obtained by subtracting a third grayscale value pertaining to the first grayscale value from a fourth grayscale value of an input image inputted to the at least partially transparent display panel. The input image is an image intended to be displayed on the at least partially transparent display panel.Type: GrantFiled: October 21, 2015Date of Patent: October 24, 2017Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Masahiko Yoshiyama, Hiroshi Ohishi, Takashi Yasuoka

Patent number: 9478046Abstract: An image processing device includes a hue changer and a color gamut converter. The hue changer changes a hue of input image data from a first hue to a second hue by combining a phase with a hue of a primary color when the input image data is at or adjacent the primary color, the phase being based on a hue angle phase difference between a first color gamut and a second color gamut narrower than the first color gamut. The color gamut converter preserves a hue about image data from the hue changer and converts a color gamut from the first color gamut to the second color gamut.Type: GrantFiled: December 5, 2014Date of Patent: October 25, 2016Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Hiroshi Ohishi, Seiki Takahashi
