  • Patent number: 10180571
    Abstract: A head-up display apparatus includes a light source portion that projects light from a light source, a screen member that has a diffusion portion inclined with respect to a hypothetical reference line that extends along a projection direction of the light from the light source, and a light-transmissive optical element that is disposed between the light source portion and the diffusion portion and has a first optical surface exposed to the light source portion and a second optical surface exposed to the diffusion portion. The projection direction corresponds to a center of the image. The diffusion portion diffuses the light from the light source. A distance between the first optical surface and the second optical surface increases in a direction from a side on which the diffusion portion is closer to the light source portion to a side on which the diffusion portion is farther from the light source portion.

  • Publication number: 20180373028
    Abstract: A projector projects a polarized light of an image. A light guide portion guides the light toward a projection member. A polarizing plate on an optical path has a transmission axis along which transmittance of the polarized light becomes maximum. An image longitudinal direction is along a vertical direction of a vehicle. An image lateral direction is perpendicular to the image longitudinal direction. A projection polarization azimuth angle is an azimuth angle of a polarization direction of the light relative to the image lateral direction. A transmission axis azimuth angle is an azimuth angle of the transmission axis of the polarizing plate relative to the image lateral direction. The polarizing plate makes the projection polarization azimuth angle different from the transmission axis azimuth angle to tilt the polarization direction of the light of the image relative to both of the image longitudinal direction and the image lateral direction.

  • Patent number: 10144317
    Abstract: A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72. A hole (slot hole 74) is formed in a bottom of the groove 73 along the groove 73. A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76A provided along the groove 73, and a connecting portion (detour portion 76B) detouring around the hole and connecting the tuck-in portions 76A. With this configuration, when an upper body of an occupant P subsides into a seat back S2 in a rear-end collision of a vehicle, the central portion 71, defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72. Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.

  • Publication number: 20180081172
    Abstract: A head-up display apparatus mounted on a moving body. The head-up display apparatus projects an image on a projecting portion. The head-up display apparatus includes a light source portion, an imaging element, a cold mirror, and a phase shifter. The light source portion emits a source light. The imaging element generates the image and outputs the light of the image. The light of the image has a predetermined polarization state. The cold mirror reflects the light of the image toward the projecting portion. In the cold mirror, an optical multilayer film is disposed on a translucent base member, and the light of the image obliquely enters the cold mirror along a plane of incidence of the cold mirror. The phase shifter converts the light of the image into an S wave. The phase shifter is disposed on an optical path between the imaging element and the cold mirror.

    Abstract: A coding device and method, a decoding device and method, and a coding/decoding system including the coding device and the decoding device are provided. The coding device includes a predictive value data generator, a predictive error data generator, a variable-length coded data generator that codes the predictive error data to sequentially generate variable-length coded data, in which a code length is variable and equal to or shorter than a set maximum length, and a coding controller. The coding controller sequentially calculates an accumulated value by accumulating a difference between the code length of the variable-length coded data and a target code length, and sequentially sets the maximum code length based on the accumulated value and the number coding time performed by the coder such that the accumulated value is zero or lower.
