An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.

There is provided an image processing apparatus comprising. An obtainment unit obtains a first circular fisheye image accompanied by a first missing region in which no pixel value is present. A generation unit generates a first equidistant cylindrical projection image by performing first equidistant cylindrical transformation processing based on the first circular fisheye image. The generation unit generates the first equidistant cylindrical projection image such that a first corresponding region corresponding to the first missing region has a pixel value in the first equidistant cylindrical projection image.

A method of installing a camera unit including an imaging device and an optical system that forms an optical image on a light receiving surface of the imaging device, wherein the light receiving surface includes a first area and a second area on a peripheral side of the first area, wherein an increase in an image height with respect to a unit half angle of view in the first area is larger than an increase in an image height with respect to a unit half angle of view in the second area, wherein the optical system and the imaging device are disposed such that the gravity center of the first area deviates in a first direction from the center of the light receiving surface, and wherein the method includes installing the camera unit such that the first direction is directed to an area other than a predetermined targeted area.

A tethered imaging camera encapsulated in a shell lens element of such camera enables viewing from inside and imaging of a biological organ in/from a variety of directions. A portion of camera's optical system together with light source(s) and optical detector mutually cooperated by housing structure inside the shell are moveable/re-orientable within the shell to vary a desired view of the object space without interruption of imaging process. A tether carries electrical but not optical signals to and from the camera and controllable traction cords to move the camera, and a hand-control unit and/or electronic circuitry configured to operate the camera and power its movements. Method(s) of using optical, optoelectronic, and optoelectromechanical sub-systems of the camera.

According to an embodiment, there is provided a reflector reflecting an immersive image output from a projector to a screen to allow a viewer to recognize the immersive image. The reflector comprises a central portion that is flat within a predetermined range with respect to a center of the reflector and a curved portion having a curvature out of the predetermined range.

To provide a new method for displaying a video image on a whole circumference screen. Provided is an image display device including: an emission unit configured to emit image light along a predetermined axis; a screen arranged over a whole circumference around the predetermined axis and having a cylindrical shape with the predetermined axis as a substantially central axis; and an optical unit arranged to face the emission unit with the predetermined axis as a reference, and configured to control an incident angle of the image light emitted by the emission unit, the incident angle being with respect to the screen, in which a video image displayed by the image light incident on the screen is simultaneously displayed over a whole circumference around the predetermined axis.

An image capturing apparatus includes an optical system, an image capturing unit, a posture detection unit, and a control unit. The optical system forms an image of a light beam from an object. The image capturing unit obtains image data corresponding to the light beam by the optical system. The posture detection unit detects a posture of the image capturing apparatus. The control unit determines based on the posture whether the image capturing apparatus is in a mode to perform shooting in a state in which an optical axis of the optical system faces a zenith or in a mode to perform shooting in a state in which the optical axis of the optical system faces a photographer side. The control unit changes control in a shooting operation using the image capturing unit in accordance with a result of the determination.

A quadric reflector can have an approximately conical shape. The shape can tapers from a wide base to an apex. The apex can include an aperture, a mirror, and a set of one or more optical elements. A mirror can be positioned within an overhang enclosure of the device in a plane approximately parallel to a circular cross section of the conical shape. The mirror can reflect environmental light that is reflected by the quadric reflector into the aperture or reflect light emitting from the aperture onto the quadric reflector. The overhang enclosure can have a substantially conical shape which eliminates secondary reflection resulting from the environmental light reaching the aperture twice. Using the overhang enclosure to absorb the secondary reflection eliminates or minimizes banding.
