Abstract: The present disclosure relates to a method for providing assistance to a colorist in color grading of a virtual reality video content, called VR content. The method includes receiving the VR content being graded by a color grading station and receiving position information representative of the position of at least one hand of a colorist versus the color grading station. The method further includes generating, based on the position information, visual control information showing the position of the at least one hand of the colorist versus at least one grading control element of the color grading station and displaying the visual control information together with the graded VR content on a head mounted display carried by the colorist in order to help the colorist manipulating the at least one grading control element.

Abstract: The invention consists in a method of and a device for adapting 3D content to an observer wearing prescription glasses. The method comprises the step of—providing information about prescription glasses of the observer;—calculating a value representative of the optical deviation created by the glasses from the provided information, for a given direction;—estimating a depth adjustment value as a function of the calculated value and—modifying the depth of the 3D content according to the estimated depth adjustment value.

Abstract: A method for evaluating color differences of pixels is provided. The method comprises obtaining color information of a first pixel in a color opponent space obtaining color information of a second pixel in the color opponent space, defining a half-line in the color opponent space based on the color information of the first pixel, and determining distance between color information of the second pixel and half-line in the color opponent space.

Abstract: In one embodiment, it is proposed a method for displaying a 3D content on a multi-view display device, said multi-view display device being able to display k-views, with k an integer greater or equal to two, said method being implemented on said multi-view display device. Such method is remarkable in that it comprises: obtaining a user's input being a depth level and/or a viewpoint; modifying said user's input in function of at least one configuration parameter, said modifying defining a group of images, said images from said group being spatially successive images of a scene at a same time; and displaying k-views on said multi-view display device, said k-views being obtained from a process taking into accounts elements from said group of images.

Abstract: The method comprises, in addition to emission periods, depolarization periods during which a predetermined depolarization voltage, which exhibits a polarity opposite to the polarity opposite to the voltage applied during the emission periods, is applied and sustained at the control terminal of said driver circuits of the panel, and a reference depolarization voltage, which is different from the reference emission voltage, is applied to the reference electrodes to which reference terminals of the driver circuits are linked. This method makes it possible to use conventional and inexpensive column control means.

Abstract: A method and an apparatus for adapting a number of views delivered by an auto-stereoscopic display device are presented. The method is executed by an electronic device, and it comprises: determining a number of views based on a list of number of views supported by the auto-stereoscopic display device and at least an information indicative of a computing power of a device needed to deliver content for each view; obtaining a correspondence map between sub-pixels of the auto-stereoscopic display device and the number of views; and providing content to the sub-pixels of the auto-stereoscopic display device according to the correspondence map.
