Abstract:
A method of estimating a parameter of a three-dimensional (3D) display device includes estimating a transformation parameter between a camera and a display based on an image displayed on the display and an image reflected by a reflector.
Abstract:
Provided are an image processing device, a method for operating the image processing device, and a system including the image processing device. A method of generating an image of a display system including a projector may include determining first external parameters of the projector, determining second external parameters of the projector in accordance with a variation of the projector, comparing the first external parameters and the second external parameters and calculating a variation amount corresponding to the variation of the projector, and generating a modified input image of the projector on the basis of the variation amount.
Abstract:
A method and a device for rendering are provided. An image can be generated by cone tracing which is beam tracing using a cone having a thickness. The thickness of the cone can be adjusted such that a hole is not generated in the image.
Abstract:
An apparatus and method for predicting an eye position includes a storer configured to store detected position information of an eye of user during a sample time interval, a calculator configured to calculate a weighted average value of a variation of the detected position information, and a predictor configured to generate prediction position information of the eye of user at a target time based on the weighted average value, and the calculator is configured to apply a weight to the variation of the detected position information such that the weight increases as the target time is approached during the sample time interval.
Abstract:
An apparatus for recognizing a pupillary distance for three-dimensional (3D) display includes a display configured to output a 3D image corresponding to a reference pupillary distance, a controller configured to control a viewing cone included in the 3D image, and a user inputter configured to receive a user feedback indicating whether an artifact is viewed in the 3D image in response to the controlling of the viewing cone. The controller may move the viewing cone within a margin corresponding to the reference pupillary distance, and change the reference pupillary distance or determine the reference pupillary distance to be a desired pupillary distance of the user based on the user feedback.
Abstract:
A method of determining a calibration parameter for a three-dimensional (3D) display device includes determining a calibration parameter for a 3D display device based on an image of a second pattern three-dimensionally converted from an image of a first pattern.
Abstract:
An image processing method and apparatus for a three-dimensional (3D) display device that may process image data for a first panel to generate an image for a second panel based 3D display device, is provided.
Abstract:
An image rendering apparatus and method for rendering a stereoscopic image are provided. The image rendering apparatus may estimate a disparity of an image pixel included in an input image. Based on the disparity, a viewpoint direction of the image pixel may be determined by the image rendering apparatus. The image rendering apparatus may render a stereoscopic image by assigning a pixel value of the image pixel to a display pixel having a viewpoint direction corresponding to the viewpoint direction of the image pixel, instead of generating a multiview image.
Abstract:
