摘要:
Provided are an apparatus and method for processing a three-dimensional (3D) video signal which corrects first and second video signals to prevent a reduction in a 3D effect and a disparity estimation error due to a difference between the first and second video signals. The method includes: a video signal detection unit detecting a difference between respective characteristics of received first and second video signals; and a video signal correction unit correcting the first video signal or the second video signal to equalize the characteristics of the first and second video signals. When the apparatus and the method are used, a reduction in the 3D effect and the disparity estimation error due to the difference between the first and second video signals can be prevented.

A high-resolution display displaying an image on a screen includes an illumination optical system, an image optical system, a pixel moving optical system, and a projection optical system. The illumination optical system includes a light source emitting a light. The image optical system includes an image forming device modulating an incident light to form the image. The pixel moving optical system includes a prism array deflecting the light from the image optical system to move pixels of the image to increase a number of pixels. The projection optical system includes a projection lens projecting the deflected light by the pixel moving optical system onto the screen.

A spiral lens disk and a projection system adopting the same are provided. The spiral lens disk has spirally arranged cylinder lens cells and scrolls incident light by converting the rotation of the cylinder lens cells into rectilinear motion of a cylinder lens array. The projection system includes at least one spiral lens disk such that color scrolling is achieved using a single component to form a color image. Due to a reduction in the number of components, a light, low-price projection system can be obtained, and a single-panel projection system with high light efficiency can also be obtained.

A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelenght. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.
