  • Publication number: 20190162978
    Abstract: There are several types of plenoptic devices having their proprietary file format. At present there is no standard supporting the acquisition and transmission of multidimensional information for an exhaustive over-view of the different parameters upon which a light-field depends. As such acquired light-field data for different cameras have a diversity of formats. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is thus introduced. The method according to the invention enables to provide data representative of a collection of pixel beams describing a first optical system that is agnostic since these data are obtained by imaging the collection of pixel beams through a second optical system. Such data representative of a collection of pixel beams enable the generation of parametrized output images from which post-processing.

  • Publication number: 20190158736
    Abstract: A system and method for generating high resolution images using a plenoptic camera having a main lens in front of an array of microlenses and an image sensor, characterized in that it comprises: capturing a first set of images in a first unexcited state of operation by using a birefringent medium disposed between a said main lens and an said array of microlenses, said unexcited state of said birefringent medium providing an ordinary ray to each pixel; causing said first unexcited state to become a second excited state by applying a voltage across said birefringent medium; capturing a second set of images in said second excited state, said excited state of said birefringent medium splitting the light from said main lens into an ordinary ray and an extraordinary ray, said extraordinary ray being shifted by a distance of one half-pixel from the ordinary ray on said image sensor; subtracting pixel value associated with said first set of images from at least two times the pixel value associated with said second se

  • Publication number: 20190101765
    Abstract: There are several types of plenoptic devices and camera arrays available on the market, and all these light field acquisition devices have their proprietary file format. However, there is no standard supporting the acquisition and transmission of multi-dimensional information. It is interesting to obtain information related to a correspondence between pixels of a sensor of said optical acquisition system and an object space of said optical acquisition system. Indeed, knowing which portion of the object space of an optical acquisition system a pixel belonging to the sensor of said optical acquisition system is sensing enables the improvement of signal processing operations. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera along with a compact format for storing such information is thus introduced.

  • Publication number: 20180262776
    Abstract: In one embodiment, it is proposed a method for encoding a light field content. The method is remarkable in that it comprises: —obtaining, for a set of light rays (401) associated with said light field content, four coordinates per light ray from a two planes parametrization (2000; 402, 403) of said light field content; —obtaining (2001), for each light ray from said set, two coordinates from said four coordinates, corresponding to a projection of said light rays from said set onto a plane (404, 405, P) perpendicular to two planes used in said two planes parametrization, defining points in a first 2D ray diagram (?(?1, ?2), ?(?1, ?2)); —applying (2002) a discrete Radon transform on said first 2D ray diagram (?(?1, ?2), ?(?1, ?2)) that delivers lines of interest in said first 2D ray diagram; —encoding (2003) said lines of interest into encoded lines of interest; and —storing (2004) said encoded lines of interest.

  • Patent number: 8009354
    Abstract: A Fresnel lens comprises at least one first prism and one second prism. Each prism has a first side and a second side which forms with a main axis an angle greater than that formed by the first side and the main axis. Conventionally, the second side of the first prism collimates the light received from a light source in line with the main axis. In order to improve the optical effectiveness, the second side of the second prism transmits the light received from the source in a first direction slightly different from the main axis.

  • Patent number: 7586703
    Abstract: A sequential illumination system for a visual display unit has a light source emitting a polychromatic light beam towards the visual display unit within a wavelength range having at least three primary colors, and a color wheel provided with at least three transmissive or reflective segments for transmitting the light beam along an optical path in such a way that they successively cut the direction of propagation of the beam. The colour segments are distributed on the wheel in such an order that the differences of energies perceived by the visual organ of a standard observer (visual stimuli), are as equivalent as possible during the intersegment transitions, when the segments pass along the optical path of the beam. The illumination system can be used for movie overhead projection devices.

  • Patent number: 7342728
    Abstract: The invention relates to a Fresnel lens. Each refractive structure of the lens is bounded by two surfaces, the second surface making a second angle with the normal to the plane of incidence. At least two zones of refractive structures are provided in which the second angle is equal to the entrance angle of a beam. Each first surface refracts the light along a direction parallel or not parallel to the axis of the lens depending on the zone. The invention also relates to a system comprising a folding mirror and a Fresnel lens, in which system the second angle is equal to the entrance angle of a parasitic ray obtained by reflection on the Fresnel lens and then on the mirror. The invention also relates to a corresponding back projection screen and a corresponding back projection unit.
