摘要:
A two dimensional/three dimensional (2D/3D) switchable autostereoscopic display apparatus and method to selectively display a 2D image and a 3D image using two displays and a convertible lens. When outputting the 2D image, the 2D/3D switchable autostereoscopic display apparatus may control a first display to output a white image/white light, control a second display to output an image, and control an electrical diffuser lens of the convertible lens to be switched off and the white image to be diffused so as to operate as a backlight. When outputting the 3D image, the 2D/3D switchable autostereoscopic display apparatus may control the first display to output an image, control the second display to be switched off to be in a transparent state, control the electrical diffuser lens of the convertible lens to be switched on to be in the transparent state, and control the lenticular lens to output the 3D image.

A rendering system and method based on a weighted value of a sub-pixel region are provided. The rendering system may change a pixel value of a single sub-pixel using pixel values of sub-pixels that represent, as respective central viewpoints, a plurality of viewpoints represented by the single sub-pixel based on an inclined lens, and may perform rendering using the changed pixel value.

Disclosed are a method for driving a glasses-type stereoscopic display preventing visual fatigue and refractive index-variable shutter glasses. The method includes generating a plurality of left-eye viewing point images and a plurality of right-eye viewing point images. The plurality of left-eye viewing point images and right-eye viewing point images have viewing points different from each other. An initial left-eye viewing point image and a subsequent left-eye viewing point image of the plurality of left-eye viewing point images are output, and an initial right-eye viewing point image and a subsequent right-eye viewing point image of the plurality of right-eye viewing point images are output. Each of the plurality of left-eye viewing point images and right-eye viewing point images is inputted into a single pupil. The glasses include a refractive index control unit to control a strength of an electric field to vary a refractive index of the glasses.

Disclosed is an image display device and an image display method thereof that may generate a plurality of directional lights based on a number of views of an input image by using a variable scattering feature of a variable scattering layer included in a backlight unit, and may output a multi-view image by using the generated plurality of directional lights.
摘要:
A method and apparatus for fast generation of a hologram image. The method may include generating an elemental fringe pattern of a three-dimensional (3D) point included in a 3D spatial object, generating a point hologram based on the elemental fringe pattern, and generate a 3D hologram using a hologram pattern for each depth layer, generated using the point hologram.

A method and apparatus for fast generation of a hologram image. The method may include generating a point hologram corresponding to each three-dimensional (3D) point using sub-sampling, generating a hologram pattern using the generated point hologram, and generating a 3D hologram by interpolating the generated hologram pattern.

Provided is a display apparatus that may estimate a degree of visual fatigue corresponding to an input 3-dimensional (3D) image, using a visual fatigue model to estimate the degree of visual fatigue of a user. The display apparatus may reduce the degree of visual fatigue of the user by rescaling a depth level of the input 3D image based on the degree of visual fatigue.

An image display apparatus and method are disclosed. The image display apparatus includes a light source unit to include at least one light source, an optical unit to generate a directional light using a light projected from the light source unit, a variable diffuser unit to control diffusion of the directional light, a pixel unit to selectively generate one of two-dimensional (2D) images and three-dimensional (3D) images to correspond to the control of the variable diffuser unit, and a vertical diffusion unit to diffuse the 3D images in a vertical direction.
摘要:
Disclosed is an inter-view crosstalk reduction apparatus and method. The inter-view crosstalk reduction apparatus applies a different margin value based on a spatial location of an image, the margin value being used to compensate for crosstalk, performs smoothing of a margin image, and applies a margin only to a portion where the margin is utilized, thereby decreasing crosstalk.
