Description

Method for outputting stereoscopic image using LC type projector and apparatus therefor {Method for outputting stereoscopic image using LCoS projector and apparatus therefor}

The present invention relates to a stereoscopic image output method and apparatus for the same, and more particularly to a stereoscopic image output method using a LCoS type projector and an apparatus therefor.

Advances in information and communication technology have enabled multimedia services that support two-dimensional video and voice to digital terminals that process text, voice, and video at high speeds. It is expected to develop.

In general, a method of implementing a stereoscopic image (or a 3D image) is implemented by illuminating different images on two eyes of a human, and a stereoscopic image display device uses separate glasses for illuminating different images on two eyes. Depending on whether or not it is necessary, it is divided into a three-dimensional stereoscopic image display device and a non-stereoscopic 3D image display device.

Among them, in the case of a three-dimensional image screened through a large screen such as a theater, a polarization method that distinguishes and transmits a left image and a right image through polarizing glasses having polarizing lenses in a direction perpendicular to each other is mainly used. . It captures images using two cameras, displays the two images with a right angle deviation of each other on one screen by using polarization means, and images taken by the two cameras through the polarizing glasses described above. The three-dimensional image is implemented by viewing the left and right eyes respectively.

1 is a view showing the structure of a conventional two-projector system for displaying a stereoscopic image.

In order to perform stereoscopic image display by the polarization method as described above, in the conventional two projector system, the left image is irradiated on one projector 1 by two conventional two-dimensional (2D) projectors 1 and 2, The other projector 2 allows the right image to be irradiated so that each of these images is irradiated onto the screen 5 by passing through the polarization filters 3 and 4 whose polarization directions are perpendicular to each other. The left image and the right image, which are irradiated on the screen 5, overlap the left and right sides of the viewer through each of the left image lens 7 and the right image lens 8 of the polarizing glasses 6 worn by the viewer. It is a way of making three-dimensional impressions by looking inside.

As described above, the conventional two-projector stereoscopic image screening system uses two conventional two-dimensional image projectors as described above, and includes a peripheral device. In addition, as the two projectors are used, the number of projectors required to display the same number of movies in a theater is doubled, and the position at which the left image and the right image are irradiated on the screen according to the positions between the two projectors. If the position between the two projectors is not adjusted correctly, there is a problem that the degree of registration of the stereoscopic image is poor.

Therefore, there has been a need for a single projector system for a stereoscopic image display system, and accordingly, a system of dividing a region of a conventional 1 projector LCD module and a method using an LCD shutter has been developed.

2 is a diagram illustrating a structure of a system according to a region classification method of a conventional LCD module for displaying a stereoscopic image.

The stereoscopic image screening system according to the area classification method of the conventional LCD module as shown in FIG. 2 reflects the light generated from the light source 201 using the reflector 202 to pass the light through the LCD module 203. The left image and the right image are distinguished from each other so as to have different polarization directions, and are irradiated to the screen 205 via the condenser lens 204. The left image and the right image irradiated to the screen 205 are then passed through the left image lens 206a and the right image lens 206b of the polarizing glasses 206 worn by the viewer, respectively, so as to feel a three-dimensional effect. Is implemented.

Specifically, as the light passes through the LCD module 203 described above, the left image and the right image have different polarization directions from each other as follows.

The LCD module 203 includes two polarizing films 209 and 210, each polarizing film having two polarization directions orthogonal to each other as shown in FIG. 2 (for the polarizing film 209). Two regions of the first polarization region 209a and the second polarization region 209b and two regions of the third polarization region 210a and the fourth polarization region 210b alternate with respect to the polarizing film 210 in the linear direction. It is arranged. As a result, the light displaying the left image among the light reflected by the reflector 202 passes through the first polarization region 209a of the one polarizing film 209 included in the LCD module 203 and the right image. Light passing through the second polarization region 209b having the phase difference of 90 degrees with the first polarization region 209a of the same polarizing film 209 is to have a polarization direction orthogonal to each other. Thereafter, the liquid crystal unit is driven according to whether each image is displayed, and when the respective images are irradiated, the left image has a phase difference of 90 degrees with the first polarization region 209a of the other polarizing film 210. The right polarized image passes through the three polarizing films 210a and the right image passes through the fourth polarized region 210b having a phase difference of 90 degrees with the second polarized region 209b among the polarizing films 210 described above. The images have polarization directions orthogonal to each other. Accordingly, the left image and the right image having the polarization directions orthogonal to each other through the condensing lens 204 are alternately arranged, which are distinguished and recognized through the polarizing glasses 206 of the viewer. Will be.

However, as described above, a method of displaying a stereoscopic image by region classification of the LCD module 203 has a disadvantage in that the overall resolution is lowered by dividing the portion where the left image is displayed and the portion where the right image is displayed. That is, as the area where each image is displayed on the entire screen becomes smaller, the resolution of the image passing through each lens of the polarizing glasses is inevitably lowered, which may have limitations when used in a large-sized theater.

In addition, there is a problem that the quality of the stereoscopic image is deteriorated if the left image and the right image do not pass through the predetermined area. Such a problem is difficult to avoid when the left image and the right image are processed in a spatial manner, and when a stereoscopic image is displayed on a large screen, such as in the theater, a small position mismatch on the projector side is stereoscopic on the viewer side. Since the degree of registration of the image can be greatly reduced, it is not easy to adjust the position at which the left and right images are illuminated.

3 is a diagram illustrating the structure of a conventional LCD shutter system for displaying stereoscopic images.

As described above, in order to solve a problem that may occur when the left and right images are spatially separated in the one projector method, the method shown in FIG. 3 produces three-dimensional image content such that the left image and the right image are sequentially repeated. The LCD shutter 302 is used to have different polarization directions from each other.

That is, the left image and the right image are sequentially stored in the content itself, and when the projector 301 irradiates an image according to the content, the LCD shutter 302 uses the projector 301 to irradiate the left image. The LCD shutter 302 is driven to have a polarization direction according to the timing, and the LCD shutter 302 to have a polarization direction different from the polarization direction for the left image described above at the timing when the projector 301 irradiates the right image. How to drive it. This may be performed by the shutter driver 303 driving the LCD shutter 302.

However, as described above, in a system for displaying a stereoscopic image using the LCD shutter, there is a problem in that cross talk occurs between the left image and the right image due to a delay in response time caused by driving the LCD shutter. . In particular, the switching time of the left and right images which are sequentially repeated should not be felt by humans, and when the left and right images are quickly switched, the slow response time of the LCD shutter may be a big problem.

In addition, the polarization rate of the left and right images by the LCD shutter is not so high, there is a demand for a technique for performing this by other means.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following detailed description, together with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced.

The following detailed description includes specific details in order to provide a thorough understanding of the present invention. However, one of ordinary skill in the art appreciates that the present invention may be practiced without these specific details. In some instances, well-known structures and devices are omitted or shown in block diagram form, centering on the core functions of each structure and device, in order to avoid obscuring the concepts of the present invention. In addition, the same components will be described with the same reference numerals throughout the present specification.

First, the type and characteristic of the driving method of the projector will be briefly described, and then the present invention will be described.

A projector is a device that receives signals from various video devices and irradiates an enlarged image through a lens on a screen. It is largely a liquid crystal display (LCD) method, a digital light processing (DLP) method, and a liquid crystal on silicon (LCoS) method. Separated by.

4A to 4C are diagrams conceptually showing driving principles of LCD, DLP, and LCoS type projectors, respectively.

First, referring to FIG. 4A, an LCD projector is a projector in which light generated from a lamp emitting strong light passes through a transmissive LCD panel and then forms an image on a front screen by a lens. As the device used is an LCD panel, the resolution of the projector is determined according to the resolution of the LCD panel. Since there is no deflection change due to the change of the input frequency, it has a strong side with respect to the PC input.

In particular, in the case of the three-panel LCD type projector, the light passing through each of the panels of red, green, and blue matches the optical axis through the prism to make the light come out from one light source, and then passes through the lens. There is no difficulty in adjusting focus and convergence. Therefore, it is easy to install, small in size, and can realize a relatively bright image. However, due to the reactivity of the liquid crystal device, there is a problem of response speed in a video screen and a weakness of black and white expression. In addition, as shown in FIG. 4A, since the droplet driving circuit is present in the panel, an inter-pixel grid may appear on the screen.

Next, referring to FIG. 4B, a DLP type projector is a projector using a semiconductor optical switch incorporating a fine driving mirror. The aluminum alloy micromirrors formed in each cell of the static random access mechanism (SRAM) have an inclination of about 10 degrees per on / off state, and the micromirrors operate by the electrostatic action of the memory disposed immediately below. By adjusting the time at which the light projected by the fine mirror is reflected or not reflected, the person can see the brightness corresponding to the time accumulated value, thereby adjusting the contrast for each pixel of the screen.

It is also generally driven in a three-plate type, and separates the light of each of the red, green, and blue to provide the respective light to the device responsible for the three colors. This DLP type projector has an excellent illuminance ratio, and the screen is clean because there is no influence of noise. In addition, since it is a complete silicon device, it has excellent durability, but the primary color expression power is significantly lowered, and there is a problem that a color break phenomenon may appear on the upper edge of the screen.

Finally, referring to FIG. 4C, an LCoS type projector uses liquid crystal as an image element, and the liquid crystal is located between the silicon substrate and the glass substrate. In addition, a mirror for reflecting light from the lamp is disposed on one side of the silicon substrate, and a circuit for driving the liquid crystal is disposed behind the silicon substrate. LCoS type projectors emit circularly polarized light of red, green, and blue light. In general, the circular polarization direction of green light is opposite to the circular polarization direction of red and blue light.

The LCoS type projector can irradiate images without a grid, and can display high resolution images even as a small panel. It also has a responsive speed for excellent video depiction. The present invention proposes a three-dimensional image system using the above-described LCoS-type projector, the LCoS-type projector may also be referred to as Sony's SXRD (Silicon X-tal Reflective Display) type projector.

5A and 5B are diagrams illustrating a difference depending on the presence or absence of a stereoscopic image lens adapter when stereoscopic image content is input to an LCoS type projector. First, FIG. 5A illustrates an image output from an LCoS type projector when a stereoscopic image lens adapter is not attached. In particular, FIG. 5A defines a single image frame in which a left image frame and a right image frame are arranged up and down in an LCoS type projector. Therefore, when the stereoscopic image lens adapter is not attached, only one image frame may be irradiated as shown in FIG. 5A.

5B illustrates a case where a stereoscopic image lens adapter is attached to an LCoS type projector. The stereoscopic image lens adapter classifies and irradiates the one image frame into a left image frame and a right image frame. That is, the left image frame and the right image frame overlap the screen and are irradiated. However, in order to distinguish the left image frame and the right image frame through polarized glasses, it is necessary to reverse the circular polarization direction of one of the left image frame and the right image frame, and the polarization direction of green light due to the characteristics of the LCoS type projector. Again modifications are needed. A detailed implementation method thereof will be described below.

6 is a diagram showing the structure of a stereoscopic image projector system according to an embodiment of the present invention.

As shown in FIG. 6, a stereoscopic image projector system according to an embodiment of the present invention uses a single LCoS method for irradiating one image frame including a left image frame and a right image frame using red, green, and blue light. And a projector 601, a stereoscopic image lens adapter 602, and a screen 606 for dividing and irradiating the left image frame and the right image frame. In particular, the stereoscopic image lens adapter 602 includes a left lens module 603a and a right lens module 603b. In addition, the delay module 604 for delaying the phase of the image frame attached to one of the left lens module or the right lens module by λ / 2 and the image frame irradiated from the lens module to which the delay module is not attached. A brightness correction module 605 for correcting brightness.

A detailed operation of the stereoscopic image projector system will be described below.

First, the projector 601 receiving the stereoscopic image content sequentially irradiates an image frame in which the left image frame and the right image frame are disposed up and down according to the information of the content.

In addition, the left lens module 603a and the right lens module 603b included in the stereoscopic image lens adapter 602 may be configured to irradiate the image frame in which the left image frame and the right image frame are arranged up and down on the screen. In the frame, the left image frame and the right image frame are aligned and irradiated to the screen. Here, it is preferable that the irradiation position of the left image frame and the right image frame irradiated on the screen are exactly matched.

However, the left image frame and the right image frame are circularly polarized due to the characteristics of the LCoS method, and the phase of the green light is circularly polarized in the opposite direction to the phases of the red and blue light. Therefore, the left lens module or the right lens module The delay module 604 attached to one front end delays the phase of the image frame irradiated by the attached lens module by λ / 2. In FIG. 6, for convenience of explanation, the phase of the image frame irradiated from the right lens module 603b is delayed. However, the phase of the image frame irradiated from the left lens module 603a may be delayed. Do.

In addition, when the phase of the image frame irradiated by either the left lens module 603a or the right lens module 603b is delayed by λ / 2, a problem may occur in that the brightness is reduced. That is, the brightness of the left image frame and the right image frame do not match. Accordingly, the image frame irradiated from the lens module to which the delay module 604 is not attached among the left lens module 603a or the right lens module 603b is attached to the delay module 604 in the brightness correction module 605. It is preferable to correct the brightness of the image frame irradiated by the lens module to be the same.

In addition, the delay module 604 and the brightness correction module 605 may be implemented as components of the stereoscopic image lens adapter 602, which is obvious to those skilled in the art. to be.

Hereinafter, the change in the polarization direction in each of the image frame irradiated from the left lens module 603a and the image frame irradiated from the right lens module 603b will be described in more detail with respect to an implementation method of the present invention.

7A and 7B illustrate a process of performing a 3D image output method using an LCoS type projector according to an embodiment of the present invention. In particular, FIGS. 7A and 7B are for explaining the function of the delay module 604.

First, FIG. 7A illustrates a circular polarization direction of each of the left image frame and the right image frame without the delay module 604 attached, and each image frame is divided into red, green, and blue light.

Assuming clockwise circular polarization is performed, the circular polarization directions of the left image frame and the right image frame are the same as shown in FIG. 7A. However, it can be seen that the circular polarization direction of the green light of each image frame is opposite to the circular polarization direction of the red light and the blue light due to the characteristics of the LCoS type projector 601. However, in order to view a stereoscopic image through stereoscopic glasses, the polarization directions of the respective image frames are reversed, and the polarization directions of the red, green, and blue light in each image frame should be the same.

Next, FIG. 7B illustrates the circular polarization direction of each of the left image frame and the right image frame when the delay module 604 is attached. As described above, the delay module 604 delays the phase of one of the left image frame and the right image frame by λ / 2. In particular, in FIG. 7B, the delay module 604 is arranged to delay the phase of the image frame irradiated from the right lens module 603b. However, the delay module 604 is implemented to delay the phase of the image frame irradiated from the left lens module 603a. It is also possible. Referring to FIG. 7B, it can be seen that the polarization directions of red and blue of the left image frame and green of the right image frame coincide with each other. Similarly, the polarization directions of red and blue of the right image frame and green of the left image frame correspond to each other.

FIG. 8 is a plan view illustrating polarization directions of a left image and a right image in a stereoscopic image output system according to an exemplary embodiment of the present invention.

Referring to FIG. 8, as described above, the polarization directions of the red, blue, and right image frames of the left image frame coincide with each other, and the polarization directions of the red, blue, and green image frames of the right image frame coincide with each other. Able to know. Therefore, when the irradiation positions of the left image frame and the right image frame are exactly matched by the stereoscopic image lens adapter, the viewer may combine the red of the left image frame with the green of the right image frame and the green of the right image frame through polarized glasses. And a combination of red and blue of the right image frame and green of the left image frame may be recognized as a left stereoscopic image frame.

Therefore, according to the present invention, by using one LCoS type projector that can support high resolution according to the present invention, the image quality of the stereoscopic image can be maximized, and the stereoscopic image can be realized by simply attaching the stereoscopic image lens adapter to the existing LCoS type projector. The installation cost can be reduced. In addition, the three-dimensional image lens adapter of the present invention has the advantage that it is simply installed in the front of the conventional LCoS type projector can be used simply.

In the above, a stereoscopic image output method using a single LCoS type projector and an apparatus therefor have been proposed. However, the present invention may also be applied to a case of using two LCoS type projectors. In more detail, if the outputs of the LCoS type projector for the left image frame and the LCoS type projector for the right image frame can be irradiated to be exactly overlapped with the screen, the stereoscopic image of the present invention is provided only by the delay module and the brightness correction module. It is obvious to those skilled in the art that an output method and an apparatus therefor can be implemented.

The detailed description of the preferred embodiments of the invention disclosed as described above is provided to enable any person skilled in the art to make and practice the invention. Although the above has been described with reference to the preferred embodiments of the present invention, those skilled in the art will variously modify and change the present invention without departing from the spirit and scope of the invention as set forth in the claims below. I can understand that you can. Accordingly, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
