Abstract
The stereoscopic image providing apparatus according to the present invention is a stereoscopic image providing apparatus including an image display apparatus for displaying an image on a screen and a liquid crystal shutter eyeglass receiving a liquid crystal driving synchronization signal from the image display apparatus, The liquid crystal shutter eyeglass includes a spectacle side receiving portion for receiving a signal from the image display device, a frame portion to which the left and right liquid crystal is coupled, a spectacle leg portion coupled to both ends of the frame portion, A power supply unit for supplying power to the left and right liquid crystal and control unit; a switch unit for activating the power supply unit; and a transmission unit for transmitting the power supply unit to the image display device when the power supply unit is activated Wherein the image display device includes a display device receiving unit for receiving a signal from the transmitting unit, And the image display apparatus is configured to convert a two-dimensional image into a three-dimensional image when the switching unit receives the on-signal from the display unit.
According to the present invention, when a stereoscopic image providing apparatus such as a TV receives a power-on signal of the liquid crystal shutter glasses, it is converted into a three-dimensional image image from a two-dimensional image, When the off signal is received, the three-dimensional image is converted into a two-dimensional image.
Description
[0001] The present invention relates to a stereoscopic image providing apparatus, and more particularly, to a stereoscopic image providing apparatus which is configured to convert an image of a video display apparatus from a two-dimensional image to a three- The present invention relates to an image providing apparatus.
2. Description of the Related Art Generally, a stereoscopic image display device is a device for digitally sampling an image signal transmitted from a video card and displaying an image through a series of signal processing.
In a stereoscopic image display apparatus, a scanning method of an image signal is classified into a progressive scanning method, a non-interlaced scanning method, and an interlaced scanning method.
In the progressive scan method, an image of one frame is composed of one field image, whereas in the interlaced scanning method, an image of one frame is usually composed of two field images.
In recent years, TVs, monitors, and the like, which are configured to provide a two-dimensional image or a three-dimensional image by selecting a viewer in a state in which a two-dimensional image and a three-dimensional image are provided together, have been developed and distributed.
On the other hand, the three-dimensional stereoscopic image technique generally uses a binocular parallax, which is the largest factor for recognizing the stereoscopic effect at a short distance, to feel the stereoscopic effect of the object.
As a method for viewing stereoscopic images, 3D glasses are typically used.
The method of wearing the 3D glasses includes an anaglyph method in which blue and red sunglasses are used in both eyes, a polarization method in which polarizing glasses having different polarization directions are used, and a time- And a liquid crystal shutter glasses system (or a time division system) in which glasses equipped with liquid crystal shutters synchronized with each other are used.
Here, the method of viewing a stereoscopic image using the liquid crystal shutter glasses is a method of repeatedly turning on and off driving the left and right liquid crystal to make the user feel stereoscopic effect.
In the case of watching a stereoscopic image through the liquid crystal shutter glasses, there is a case where the glasses are worn by turning on the power of the liquid crystal shutter glasses while the TV is turned on and the case where the liquid crystal shutter glasses are powered on, I turn on and wear glasses.
In any case, turning on the liquid crystal shutter glasses when the TV is turned on is the viewer's intention to view the three-dimensional image. Turning off the liquid crystal shutter glasses means that the viewer intends not to view the three- Can be seen as.
An object of the present invention is to provide a stereoscopic image providing apparatus having a stereoscopic image providing apparatus, which is configured to convert a two-dimensional image into a three-dimensional image when receiving a signal powered on by a liquid crystal shutter eyeglass in a stereoscopic image providing apparatus, .
It is still another object of the present invention to provide a stereoscopic image providing apparatus having a stereoscopic image providing apparatus, which is configured to convert a three-dimensional image into a two-dimensional image when a power- .
According to an aspect of the present invention, there is provided an apparatus for providing a stereoscopic image having a video switching function, including: an image display device for displaying an image on a screen; a liquid crystal shutter for receiving a liquid crystal driving synchronization signal from the image display device; The liquid crystal shutter glasses according to claim 1, wherein the liquid crystal shutter glasses comprise: a spectacle side receiving part for receiving a signal from the image display device; a frame part to which the left and right liquid crystal are coupled; a pair of glasses legs coupled to both ends of the frame part; A power supply unit for supplying power to the left and right liquid crystal and control unit; a switch unit for activating the power supply unit; and a control unit for controlling the power supply unit, And a transmission unit for transmitting a signal to the apparatus, wherein the image display apparatus includes a display for receiving a signal from the transmission unit Wherein the image display apparatus is configured to convert a two-dimensional image into a three-dimensional image when the switch unit receives the on-signal from the display unit receiving unit, .
In addition, when receiving the signal that the switch unit is turned off in the display apparatus receiving unit during the provision of the three-dimensional image in the image display apparatus, the image of the image display apparatus is changed from the three- .
According to the present invention, when a stereoscopic image providing apparatus such as a TV receives a powered-on signal of a liquid crystal shutter eyeglass, the two-dimensional image is converted into a three-dimensional image.
In addition, when the stereoscopic image providing apparatus receives a signal in which the power of the liquid crystal shutter glasses is turned off, it is converted into a two-dimensional image image from the three-dimensional image.
