Embodiments include an optical system that may be included in a waveguide display. An example optical system includes a first waveguide having a first transmissive diffractive in-coupler (DG1) and a first diffractive out-coupler (DG6) and a second waveguide having a second transmissive diffractive in-coupler (DG2), a reflective diffractive in-coupler (DG3), a second diffractive out-coupler (DG4), and a third diffractive out-coupler (DG5). The second transmissive diffractive in-coupler (DG2) is arranged between the first transmissive diffractive in-coupler (DG1) and the reflective diffractive in-coupler (DG3) in an input region.

Waveguide display system with wide field of view

A method is proposed for detecting occlusions in an image captured by a light field capturing system, comprising, for at least one reference image belonging to a matrix of images captured by the light field capturing system: —calculating a depth map and a visibility map for pixels in the reference image; —determining at least one candidate area in the reference image in which the potential occlusion may occur based at least on a segmentation of the depth map; —determining an information representative of an occlusion state in the at least one candidate area based at least on visibility values of the visibility map associated with at least two neighborhoods of the at least one candidate area.

Method for detecting occlusions in an image, corresponding device and computer program product

Some embodiments of a method may include defining a triggering area, the triggering area having a border with the border being arranged, at least partially, within a positioning zone for observing a multi view content displayed on a display based on a position of a viewer; and when the viewer position is located within the triggering area, triggering one or more incentive effects. Some embodiments of an apparatus may include a processor; and a memory-storing device storing instructions operative, when executed by the processor, to cause the apparatus to: define a triggering area, the triggering area having a border with the border being arranged, at least partially, within a positioning zone, for observing a multi view content displayed on a display based on a position of a viewer; and when the viewer position is located within the triggering area, trigger one or more incentive effects.

Method and apparatus for providing information to a user observing a multi view content

The present disclosure concerns a method for displaying, on a 2D display device, a content derived from 4D light field data, based on a viewing position of a user. The 4D light field data corresponds to data acquired by either several cameras or by a plenoptic device. The method comprises: obtaining a volume in front of said 2D display device in which no disocclusions are present, said volume being defined according to optical and geometry parameters of an acquisition device that has acquired said 4D light field data, a size of a screen of said 2D display device, and an anchor plane in said content, said anchor plane being perceived as static in case of movement of a user relative to said 2D display device; determining a modified volume from said volume, comprising modifying a size of said volume, for modifying possible movements of a user positioned within the modified volume compared to movements of said user within said volume; providing means for guiding said user within said modified volume according to said viewing position of said user.

Method for displaying, on a 2D display device, a content derived from light field data

A plenoptic camera and associated method is provided. The camera has an array of sensors for generating digital images. The images have associated audio signals. The array of sensors are configured to capture digital images associated with a default spatial coordinate and are also configured to receive control input from a processor to change focus from said default spatial coordinate to a new spatial coordinate based on occurrence of an event at said new spatial coordinate.

Audio event detection for automatic plenoptic video refocusing

A method for refocusing, on at least one common point of interest, the rendering of one set of plenoptic video data provided by one plenoptic device belonging to a set of plenoptic devices capturing simultaneously a same scene. According to the present disclosure, said method comprises: obtaining () a common 3D reference system used for spatially locating said plenoptic device that has provided said set of plenoptic video data and at least one other device of said set of plenoptic devices, from said at least one common point of interest, determining () common refocusing plane parameters in said common 3D reference system, refocusing () the rendering of said set of plenoptic video data by converting () said common refocusing plane parameters into a rendering refocusing plane of a 3D reference system associated with said plenoptic device.

Method and device for refocusing at least one plenoptic video

A method for retrieving a media file from a media rendering device with an initial set of media files stored in the device. Each media file has attributed feature values stored in the device and is associated to a graphical element displayed on a display. The position of each graphical element on the display depends on a multitude of the feature values of the associated media file.

Method and apparatus for retrieving a media file of interest

The present invention relates to a method for creation of an animated series of photographs. A photograph acquisition device analyzes the images in order to detect an absence of movement. The detection of an absence of movement during a determined period triggers a photograph to be taken and the memorization of image data in the series of photographs. The user introduces a command to end the acquisition of the series of photographs. The data of different photographs taken are assembled to form an animated series. During the reproduction, the series is reproduced by displaying successively each photograph, the time between each photograph reproduction can possibly be introduced by the user. The invention also relates to a photograph acquisition device designed acquire said animated series of photographs.

Method for creation of an animated series of photographs, and device to implement the method

The present invention relates to a method for creation of a sound series of photographs. A sound series is produced by a camera and is audible to the user of the device. At various instants of the sound series, the user takes photographs and the device records the instant when the photograph was taken. A table is created associating each photograph with the instant of the sequence when it was taken. The sound sequence terminates then ending the series of photograph takes. Then, the photographs are assembled to form a single panoramic image, a part of the panoramic image is then displayed by an animation. The panoramic image thus created, the sound sequence and the table are assembled to form a panoramic sound image. During the reproduction of the panoramic sound image, each photograph is displayed at the instant associated by the table.
