Abstract:
A system for projecting changeable electronic content, such as video or digital still images, onto a curved surface. The system includes a housing, a reflector within the housing, and a projector. The housing has an exterior surface and an interior space. At least a portion of the exterior surface is a curved display surface capable of displaying electronic content projected upon it, and at least one portion of the exterior surface has an aperture through the exterior surface to the interior space. The projector is located proximate the aperture for projecting content through the aperture to the reflector. When the projector receives converted content and projects the converted content through the aperture to the reflector, the curved display surface displays the converted content undistorted to a viewer. The system can also provide for display of branded content on a product container having a shape corresponding with the brand.
Abstract:
A personal communication device, such as a smartphone handset (1) comprises a main body (2) incorporating a camera (4) having a lens (5). An attachment (6) for the personal communication device is detachably mountable to the main body (2) by means of a cover (8). The attachment (6) also comprises an optical device (7) arranged to reflect light into the lens from a panoramic field of view. The optical device (7) includes a convex mirror (9), which preferably reflects light from a 360° field of view into the camera (4). Such an arrangement enables the user to completely capture an image of his surroundings, so that the image is an objective record of a moment in time as experienced by the user. The invention is more portable and versatile than previous arrangements.
Abstract:
The invention relates to a projection device (1) that comprises: a projector (2) adapted for projecting a mother image along a projection axis (11); and a convex mirror adapted for at least partially reflecting the mother image and projecting it onto a three-dimensional environment (7, 8a, 8b) such as the ground, a ceiling, one or more side walls and the content of a room. When combining the projector with a convex mirror, the mother image can for example be projected into a solid angle higher than 2p steradians (i.e. a half-sphere), or even substantially equal to or slightly lower than 4p steradians (i.e. a sphere). The invention also relates to a method implemented by said device. The field of the invention is particularly that of video projectors for virtual or mixed reality applications.
Abstract:
La présente invention concerne un dispositif (1) de projection, comprenant : un projecteur (2) agencé pour projeter une image mère le long d'un axe de projection (11); et un miroir convexe (3) agencé pour réfléchir au moins en partie l'image mère et la projeter sur un environnement tridimensionnel (7, 8a, 8b) comme le sol, le plafond, un ou plusieurs murs latéraux et le contenu d'une salle. En combinant le projecteur à un miroir convexe, l'image mère peut par exemple être projetée dans un angle solide supérieur à 2π stéradians (c'est-à-dire une demi-sphère), voire même sensiblement égal ou légèrement inférieur à 4π stéradians (c'est-à-dire une sphère). L'invention concerne aussi un procédé mis en œuvre dans ce dispositif. Le domaine de l'invention est plus particulièrement celui des vidéoprojecteurs pour applications de réalité virtuelle ou mixte.
Abstract:
An image capturing device may include a detector including a plurality of sensing pixels, and an optical system adapted to project a distorted image of an object within a field of view onto the sensing pixels, wherein the optical system expands the image in a center of the field of view and compresses the image in a periphery of the field of view, wherein a first number of sensing pixels required to realize a maximal zoom magnification, Formula (I), at a minimum resolution of the image capturing device is less than a square of the maximal zoom magnification times a second number of sensing pixels required for the minimum resolution.
Abstract:
Imaging apparatus (510) including image creation means (514) for creating a moving image means (530) for enlarging the image, and a screen (514) on which the image is displayed in use to a viewer. The image creation means includes a substantially planar image creation screen (514) on which the image is created.
Abstract:
Imaging apparatus comprising two imaging units (12) for producing images of respective scenes, each imaging unit comprising optical means for gathering light over a wide sector and directing it to image sensing means (14). The optical means of the imaging units can be back-to-back so as to encompass the imaging sensing means (14) and each unit can include a convex reflector (16) for reflecting light from a panoramic scene onto a planar reflector (18) which reflects light through a port or ports (24) in the convex reflector (16) onto a CCD array (14) within the convex reflector. Other reflecting systems include convex, concave and planar reflecting surfaces. Also disclosed are arrangements for reducing back-workings in the back-to-back fisheye lenses; a CCD with a curved image sensing surface; light shielding means; a method of generating position signals for navigating round a panoramic scene; and a device including a segmental field of view and an annular field of view which are combined to provide a panospherical image, the image output is processed to form a composite image in a flat plane.
