Provided is an optical device that involves a simple attachment operation without the need for an adjustment process. The optical device includes a transparent body portion having a plurality of curved faces on its outer peripheral surface; and a blind-spot-side outward facing curved reflecting mirror, a blind-spot-side inward facing curved reflecting mirror, an eve-point-side inward facing curved reflecting mirror, and an eye-point-side outward facing curved reflecting mirror, which are integrally formed with the body portion. The body portion has formed therein an optical path that allows a light beam reflected by the blind-spot-side outward facing curved reflecting mirror to be sequentially reflected by the blind-spot-side inward facing curved reflecting mirror and the eye-point-side inward facing curved reflecting minor and then reach the eye-point-side outward facing curved reflecting mirror.

A cloaking device includes an object-side, an image-side, an object-side curved cloaking region (CR) boundary having an outward facing mirror surface and an inward facing surface, and an image-side curved CR boundary an outward facing mirror surface and an inward facing surface. A cloaked region is bounded by the inward facing surfaces of the object-side curved CR boundary and the image-side curved CR boundary. At least one exterior boundary with an inward facing mirror surface is spaced apart from the object-side curved CR boundary and the image-side curved CR boundary. Light from an object positioned on the object-side of the cloaking device and obscured by the cloaked region is redirected around the cloaked region to form an image of the object on the image-side of the cloaking device such that the light from the object appears to pass through the CR.

A cloaking device includes an object-side, an image-side, an object-side cloaking region (CR) reflection boundary having an outward facing mirror surface, and an image-side CR reflection boundary having an outward facing mirror surface. A cloaking region is bounded by the object-side CR reflection boundary and the image-side CR reflection boundary. An object-side lens, an image-side lens and at least one exterior reflection boundary are included. Light from an object positioned on the object-side of the cloaking device and obscured by the cloaking region is focused by the object-side lens, reflected by the object-side CR reflection boundary, the at least one exterior reflection boundary and the image-side CR reflection boundary, and focused by the image-side lens to form an image of the object on the image-side of the cloaking device such that the light from the object appears to pass through the cloaking region.

A cloaking device includes an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side. An object-side CR reflection boundary and a plurality of object-side color filters are positioned on the object side and an image-side CR reflection boundary and a plurality of image-side color filters are positioned on the image-side. The plurality of object-side color filters are spaced apart from and positioned generally parallel to the object-side CR reflection boundary, and the plurality of image-side color filters are spaced apart from and positioned generally parallel to the image-side CR reflection boundary. The plurality of object-side color filters and the plurality of image-side color filters may be co-planar and light from an object located on the object-side of the cloaking device propagates via at least two optical paths to form an image of the object on the image-side of the cloaking device.

A motor vehicle includes a loudspeaker disposed within a passenger compartment of the vehicle approximately between an occupant's seat of the vehicle and a space of interest disposed outside of the vehicle. A camera is positioned to capture images of a face of an occupant of the vehicle. A processing device receives the images captured by the camera, and determines from the images that the occupant is not looking at the space of interest disposed outside of the passenger compartment. In response to the determining that the driver is not looking at the space of interest disposed outside of the passenger compartment, the processing device causes a sound to be emitted from the loudspeaker.

A display image is obtained by superimposing an image showing a vehicle on a captured image obtained by capturing an image on a rear side from the vehicle. For example, the image showing the vehicle is a computer graphics image. For example, a change is made in a superimposed positional relationship between the captured image and the image showing the vehicle in accordance with motion of a viewpoint of a driver. Since the display image is not only made from the captured image obtained by capturing an image on a rear side from the vehicle, but the display image is obtained by superimposing the image showing the vehicle on the captured image, it is possible to easily provide a sense of distance by motion parallax.

A display device applied to an instrument panel unit includes: a projection surface provided on a surface on a vehicle interior side of an interior member provided on the vehicle interior side of a vehicle and on a front side in a vehicle front-back direction, the interior member extending along a vehicle width direction; a projector including a projection unit configured to project an image; and a holding unit configured to hold the projector by the interior member in a positional relationship where at least a part of the projection unit is located on the projection surface side of the interior member, and the image from the projection unit is projected onto the projection surface.

A vehicular rearview vision system includes a driver-side display device disposed at an interior driver side region of a vehicle and viewable by a driver of the vehicle, a first camera disposed at the vehicle so as to have at least a rearward and sideward field of view, and a second camera disposed at a driver side of the vehicle so as to have at least a sideward and forward field of view that at least partially views an A-pillar blind spot region forward and sideward of a driver-side A-pillar of the vehicle. The driver-side display device displays video images derived from image data captured by the first camera, and the driver-side display device displays driver-side A-pillar blind spot video images derived from image data captured by the second camera. The displayed rearview video images may be at least partially surrounded by the displayed driver-side A-pillar blind spot video images.

A vehicle collision avoidance system has a side-view camera positioned on a side portion of a vehicle and configured to present a driver with a rear side view exterior to the vehicle. A display is coupled to the side-view camera and disposed in view of the driver to output a video stream from the side-view camera. A turn signal sensor is configured to detect activation of a turn signal. A controller is configured to receive signals from the turn signal sensor and to adjust a field of view of the side-view camera based on activation of the turn signal.

Asymmetric sectioned mirrors are presented. The mirrors include, for example, constant radius of curvature sections that are selected to increase the sizes and improve the definitions of images, for example images of children milling, walking and/or standing about either the front or alongside regions of a school bus. The mirrors may be asymmetric in either or both the horizontal and vertical directions. The mirrors may include a mounting system capable of using both ball mounts and tunnel mounts.
