Abstract: There are provided a lens, a zoom lens, and an imaging lens capable of eliminating blurriness of a ring zone without reducing resolution and increasing the number of steps of processing. A lens 1 has random unevenness within an optical effective diameter D of an optical surface 2, an arithmetic mean roughness Ra within the optical effective diameter D of the optical surface 2 is 20 nm or more and 50 nm or less, and an average value of widths W of protrusion portions 3 of the unevenness on an average line C2 of a roughness curve C1 of the optical surface 2 is 1/200 or more and 1/50 or less of the optical effective diameter D of the optical surface 2. The lens 1 is suitably used as a lens that composes a zoom lens or an imaging lens.

Abstract: A projector includes a projection lens and a projector body. In the projection lens, a U-shaped optical path is formed by optical axis to optical axis. A lens barrel is a U-shaped barrel. A housing of the projector body includes a storage section. The projection lens is supported rotatably about the optical axis with respect to the housing, in an up-down direction and a right-left direction of the housing perpendicular to the optical axis, between a first position where the projection lens is stored inside a storage section provided in the housing and a second position where the projection lens is protruding from the housing.

Abstract: A first holding barrel, a first mirror bending a first optical axis of the first holding barrel at 90°, a second holding barrel, a second mirror bending a second optical axis of the second holding barrel at 90°, and a third holding barrel are disposed on an optical axis from a screen side to an image forming panel. A first connection member connects the first holding barrel including the first mirror to the second holding barrel to be rotationally movable in increments of 90°. A second connection member connects the second holding barrel and the second mirror to the third holding barrel to be rotationally movable in increments of 90°. An orientation of a display image of the image forming panel is changed based on rotational movement states of an optical axis of a first sensor and an optical axis of a second sensor to make an orientation of a projection image on the screen match an original image.

Abstract: A first optical system, a first mirror, a second optical system, a second mirror, and a third optical system are disposed in order on an optical axis from an image forming panel to a screen. A first optical axis of the first optical system, a second optical axis of the second optical system, and a third optical axis of the third optical system are formed in a U shape, and orientations of luminous fluxes of the first optical axis and the third optical axis are reversed. The first mirror, the second optical system, the second mirror, and the third optical system are held to make a second holding barrel with respect to the first optical system. The second holding barrel is rotationally moved in a rotational movement range of 45° with respect to a first holding barrel. In projecting portrait image instead of a landscape image, the second holding barrel is rotated in increments of 45° with respect to the first holding barrel.

Abstract: Provided are a projection-type display device, a safe-driving support method, and a non-transitory computer readable recording medium storing a safe-driving support program capable of securing safety while providing sufficient information to a driver even in a situation where a field of vision in a traveling direction of a motor vehicle is poor. An HUD includes a light modulation unit that modulates light emitted from a light source unit; a projection unit that projects the light modulated by the light modulation unit onto a combiner; a first image information generation unit that generates first image information and outputs the first image information to the light modulation unit; a second image information generation unit that generates second image information and outputs the second image information to a display device; and a control unit that controls operations of the first image information generation unit and the second image information generation unit.
