An image display apparatus 10 comprises a first display unit 12L that displays an image of what is to a left side rear of the self-vehicle V, a second display unit 12R that displays an image of what is to a right side rear of the self-vehicle V, and a third display unit 22 that displays an image of what is to a rear of the self-vehicle V. The image display apparatus superimposes first indicators 53a and 63a that indicate a distance from the self-vehicle V to the side and second indicators 53b and 63b that indicate a distance from the self-vehicle V to the rear in accordance with an image displayed on the first display unit 12L, an image displayed on the second display unit 12R, and an image displayed on the third display unit 22.

An imaging system includes a spherical window, a reflector, an image sensor, a housing and a snap ring. The reflector has a focus point located at a center of a sphere defined by an outer surface of the window. Light entering the window at an angle perpendicular to the outer surface of the window and traveling to the focus point is reflected onto the image sensor by the reflector. The window and housing have first and second grooves, respectively. In order to couple the window to the housing, the snap ring is placed in the second groove, the snap ring is compressed with the window and then the snap ring is allowed to expand so that the snap ring is located in both the first and second grooves.

[Problem] To provide a photographing apparatus that reduces motion blur caused by camera rotation, provides high quality binocular parallax video, and suppresses visually induced motion sickness. [Solution] A photographing apparatus 1 is provided with a plurality of photographing units 10 that can form an entire peripheral image, and further provided with: a photographing unit installation unit 20 in which the photographing units 10 are installed; a rotary driving shaft 30 that rotatably supports the photographing unit installation unit 20; a driving unit (motor) 40 that applies rotational force to the rotary driving shaft 30; a photographing unit shaft 50 that is provided to the photographing unit installation unit 20 so as to rotatably fix the photographing units 10 at prescribed respective positions; and driving force transmission means 60 that are provided to both the rotary driving shaft 30 and the photographing unit shaft 50 so as to transmit the rotary driving force of the rotary driving shaft 30, wherein the photographing units 10 can hold a state of facing the prescribed positions without following the rotation of the photographing unit installation unit 20 when the photographing unit installation unit 20 rotates.

Apparatuses, systems, and methods for producing non-rotationally symmetric optical aberrations. Such aberrations may be created by a removable attachment that may be attached to another lens, such as a spherical lens. Aberrations that appear to reproduce an anamorphic effect may be produced, yet the underlying camera system may remain a spherical camera system, and the capture mode may remain non-anamorphic.

Catadioptric projector systems, devices, and methods are provided in accordance with various embodiments. For example, some embodiments include a catadioptric projector that may include: a radiation source; a static pattern generating element and/or a time-varying pattern generating element configured to condition radiation from the radiation source to produce the patterned illumination; and/or a convex reflector positioned to project the patterned illumination. Some embodiments include a system that includes a catadioptric projector and a camera configured to acquire one or more images based on the patterned illumination. Systems and methods in accordance with various embodiments are provided to estimate a distance to a point on an object based on the one or more acquired images.

An imaging device incorporated in an omnidirectional video capturing system including an imager, a memory, and a transmitter. The imager includes imaging lenses to capture images from a plurality of directions. The memory stores projective transformation data. The projective transformation data includes photographing direction data representing the plurality of directions and projection data representing image heights of the images associated with angles at which light rays enter the imaging lens. The transmitter reads the projective transformation data stored in the memory, and transmits frame data of the images and the projective transformation information to an image processing device of the omnidirectional video capturing system.

The present invention provides a projection display system having a three-dimensional convex display surface, such as a spherical or hemispherical display surface, in which the condenser lens before the optical modulating device may have a reduced focal distance for focusing the light more tightly on the optical modulating device, so as to illuminate only the center portion of the optical modulating device. Alternatively, the projection display system may have a square light pipe or any shaped light pipe in the optics in order concentrate the light to illuminate only a center portion of the optical modulating device or devices. The light pipe may be at least one of a round shape, pentagonal shape, a hexagonal shape, an octagonal shape, etc.
