Disclosed is a motorized rehabilitation apparatus and method for disabled, impaired or injured individuals, which trains a proper gait, increases blood flow, relieves stress, and reconditions lower body muscles and joints. The device comprises a powered stationary bicycle having a seat, handle grips, and rotating foot pedals that receive motive input from an electric motor and user input. The device further includes a pair of thigh braces that are connected together between the user's thighs via a hingeable link and chain that controls and trains an individual's limbs through the pedal rotation. The disclosed method further combines the present bicycle device for rehabilitation in conjunction with visual stimuli in the way of a three dimensional television display that stimulates endorphins, relieves mental stress and allows the motive input from the bicycle and mild user input to exercise the limbs of a user without focusing on the rehabilitation activity.

The invention discloses a method for describing the virtual viewport image in a stereo-television system. The method comprises the following steps: 1) a left viewport texture image and a right viewport texture image are rotated to a virtual viewport to obtain the rotated image of the left viewport texture image and the right viewport texture image according to a left viewport range image and a right viewport range image; 2) the self-adapting interpolation is carried out to the left viewport texture image and the right viewport texture image to obtain the interpolation image of the left viewport texture image and the right viewport texture image; and 3) according to the interpolation image of the left viewport texture image, the superposition-type filling is carried out to the interpolation image of the right viewport texture image to obtain a virtual viewport image. By adopting the method, firstly, the left viewport texture image and the right viewport texture image are rotated to obtain the rotated image, then, the self-adapting interpolation is carried out to the rotated image to obtain the interpolation image, and finally, the superposition-type filling is carried out to the interpolation image to obtain the virtual viewport image. The method can effectively inhibit the noise caused by shading and quantization errors and improve the quality of the virtual viewport image description.

The present invention realizes stereoscopic television broadcasting which can reproduce a stereoscopic image best in state of stereoscopic viewing and a receiver for the stereoscopic television broadcasting.In stereoscopic television broadcasting, a reference size of a display of a receiver is determined, images for right and left are displayed on the display with a reference size in a superimposing manner, and transmission is performed such that a distance between the same corresponding points of an infinite subject image is reproduced and displayed to be equal to an interpupillary distance of a human.

Disclosed herein are a 3D TV and a system using RF wireless communication and a method for synchronizing a 3D TV system using the same. In the 3D TV system using the RF wireless communication according to an exemplary embodiment of the present invention, two or more 3D TVs transmit and receive synchronous signals through the RF wireless communication, thereby locking the screen synchronization and synchronous signals of the 3D TVs. Thereafter, when the 3D TVs transmits the synchronous signals to the 3D spectacles, the synchronous signals including the time offset are transmitted, having different time difference. As a result, the 3D spectacles can be synchronized with images displayed on the 3D TVs by using time offset information.

The invention discloses a laser scattering displayer. On the basis of the principle of the laser scattering displayer, lasers are used as a light source, the lasers are transmitted to pixel positions of a display screen through optical fibers, light transmission media made of special materials are arranged at the pixel positions, the media can generate physical or chemical changes under the action of currents or a magnetic field, the lasers are made to generate scattered light or transparent non-scattered light, and when the scattered light is distributed at each pixel position, the scattered light is used as pixels; when the scattered light does not exist, the pixel positions are transparent and used as laser paths, the existence of the scattered light determines whether the pixels are turned on or off, a plurality of the pixels form images, and image restoration is achieved. The laser scattering displayer is simple in production process, low in cost and suitable for television screens, computer screens, phone screens, electromechanical instruments and the like. The designed product is stable and reliable in performance and durable in use. The laser scattering displayer is more suitable for 3D televisions, three-dimensional televisions in the future and the like.
