摘要： The present technique relates to a telemedicine system, a telemedicine method, an information processing device, and a program that allow a medical practitioner to more accurately obtain visual information on a patient in telemedicine.
The telemedicine system includes a first imaging unit that images a patient in a first space, an image processing unit that corrects an image of the patient based on imaging conditions in a first space and display conditions in a second space for displaying the image of the patient imaged in the first space, and a display unit that displays the corrected image of the patient in the second space. The present technique can be applied to, for example, a telemedicine system.-

摘要： Methods, apparatus, devices, and systems for displaying three-dimensional objects by individually diffracting different colors of light are provided. In one aspect, a system includes a display having a plurality of display elements and an optical device configured to diffract a plurality of different colors of light to the display. The optical device is configured such that, when the plurality of different colors of light is incident on the optical device, the optical device separates light of individual colors of the different colors while suppressing crosstalk between the different colors.

摘要： An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.

摘要： There is provided an image processing apparatus and an image processing method by which three-dimensional data can be generated with high accuracy on the basis of two-dimensional image data and depth image data. A color shift correction data generation unit generates color shift correction data for correcting a color shift between two-dimensional image data of a base viewpoint and two-dimensional image data of a reference viewpoint. A metadata addition unit transmits color shift correction information including the color shift correction data generated by the color shift correction data generation unit, encoded data of the two-dimensional image data of the base viewpoint and depth image data indicative of a position of each of pixels in a depthwise direction of an image pickup object and encoded data of the two-dimensional image data of the reference viewpoint and depth image data. The present disclosure can be applied, for example, to a synthesis apparatus.

摘要： In a display device, an irradiation unit includes an imaging optical system. The imaging optical system scans and irradiates a front surface of a screen with light to form an image. The light passing through the screen and output from the screen in a movement direction is incident on a projection unit as incident light. The projection unit irradiates a reflective member with the incident light to allow the reflective member to reflect the incident light to form a virtual image corresponding to the image in a target space. A locus of a focal position of the imaging optical system when the irradiation unit wholly scans the front surface of the screen is within a range between the front surface of the screen at a first position and the front surface of the screen at a second position.

摘要： Methods, apparatus and systems for geometric matching of virtual reality (VR) or augmented reality (AR) output contemporaneously with video output formatted for display on a 2D screen include a determination of value sets that when used in image processing cause an off-screen angular field of view of the at least one of the AR output object or the VR output object to have a fixed relationship to at least one of the angular field of view of the onscreen object or of the 2D screen. The AR/VR output object is outputted to an AR/VR display device and the user experience is improved by the geometric matching between objects observed on the AR/VR display device and corresponding objects appearing on the 2D screen.

摘要： An image display apparatus and a method thereof. The image display apparatus includes: a display; a processor; a memory including a first buffer and a second buffer; and at least one program stored in the memory and executed by the processor. The instructions included in the program cause the processor to perform graphics processing on a first image, convert an attribute of the graphics-processed first image, generate an on screen display (OSD) image and control the memory to store the OSD image in the second buffer, perform image quality processing on the first image of which the attribute is converted, and control the display to display the image-quality-processed first image and the OSD image.
