A signal processing device performs a displaying process in a display unit on the basis of a parameter being predetermined in an image capture device provided with an anamorphic lens.

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.

An observation unit (30) for underwater deployment on/in a submerged earth layer (12) or structure. The unit comprises a housing (32), a light source (36), an underwater imaging device (40), a processor device (44), and a communication device (35). The housing supports the underwater observation unit relative to the submerged layer or structure. The light source is fixed to the housing, and configured to emit light into the unit's surroundings. The imaging device is attached to the housing, and configured to acquire image data of a second light source located within a FOV of the camera that covers the surroundings of the unit. The processor device is configured to determine positional data of the second light source relative to the imaging device, from the image data. The communication device is configured to transmit the positional data to another underwater observation unit, an underwater vehicle, or an underwater processing station.

A first mirror has a first reflecting surface convexed in a first direction, a first apex, and a first fan shape. A second mirror has a second reflecting surface convexed in a second direction, a second apex, and a second fan shape. An imaging optical system forms images from a first light emitted from an object, reflected by the first reflecting surface, and subsequently further reflected by the second reflecting surface, and a second light emitted from the object and reflected by the second reflecting surface. The first and second fan shapes have interior angles of 180° or more. A center position of the image sensor is displaced with respect to an optical axis of the imaging optical system. A short side of a photo-receiving surface of the image sensor and a center line of the image of the first or second fan shape are approximately parallel.

The present invention provides a panoramic presentation method and apparatus. The present invention presents a panoramic image by using a combined structure of a single fisheye projector and a spherical screen in hardware, employs a geometrical relationship between a fisheye lens and the position of a viewer and isometric projection transformation, and enables 180° fisheye projection to present 720° environment information to the viewer in the center of the spherical screen, greatly simplifying the image conversion process and realizing zero distortion. According to a 720° panorama one-step generation method based on a single virtual camera in software, complex steps of collecting six images by a plurality of cameras, synthesizing a cube map and then converting the cube map into a panorama are not needed, the vertex position of a scene is directly adjusted in the process from a 3D space to a 2D image

A calibration step is disclosed for use with a system and a method for creating a wide-screen picture-dominance effect in an auditorium located in a motion-picture theater. This is accomplished by an operator viewing a test image or images of horizontal and vertical lines projected onto a deeply-curved screen in said auditorium and adjusting the projection of said test image or images until the horizontal and vertical lines in said image or images appear straight and orthonormal, with the result that viewers watching motion pictures in said auditorium will observe images that appear wider than the physical confines of the auditorium in said theater.
