Korean Patent Application Laid-Open No. 10-2009-0055094 relates to an image display device, and in particular, there is one that allows image quality to be improved by selectively adjusting an offset according to an actually input signal. In other words, by adjusting the offset value fixed in the product production stage based on the black level of the currently input signal, the phenomenon of dark areas in the actual input signal is improved through accurate color gradation expression, thereby providing optimal image quality for users. There is something to offer.

The video display device includes a black level detection unit 10 for detecting a black level of an image signal input from the outside, and a black level detected through the black level detection unit 10 and a black level according to a pre-stored offset value. Set an offset value based on the black level detected by the black level detection unit 10 according to the comparison result of the comparison unit 20 and the comparison unit 20 , and the set offset value The image processing unit 30 that adjusts the image signal based on A control unit 50 for controlling to set an offset value of a currently input image signal based on do.

According to the video display device, the black level detection unit 10 detects the brightness level of each pixel of the video signal input from the outside, and detects the black level of the currently input video signal.

The black level means the lowest level in the brightness level for each pixel of the video signal that is actually input at present, and it depends on the type of input signal (RF, PC signal, etc.) and the video card currently used by the user. deviations also occur.

That is, even if the offset value is set based on the optimal black level in the product production stage, the black of the currently input signal depends on the type of the input signal to which the offset value is applied, the type of the video card, and the surrounding environment where the user is currently located. Levels vary.

Therefore, even if an optimal offset value is set in the product production stage, a phenomenon occurs in which an accurate color gradation cannot be expressed according to the black level of the currently input signal, and a dark part to be actually expressed may be buried.

Therefore, the controller 50 outputs a control signal to adjust the offset value previously set based on the black level of the currently input image signal. That is, the control unit 50 outputs a control signal so that the currently applied offset value is adjusted through the image processing unit 30 based on the black level detected by the black level detection unit 10 .

The image processing unit 30 sets an offset value to be currently applied based on the black level of the currently input image signal detected through the black level detection unit 20 according to the control signal of the control unit 50 .

That is, the image processing unit 20 sets an offset value based on the black level, which is the lowest signal level, so that the lowest signal level detected by the black level detection unit 10 is expressed, and based on the set offset value, The video signal input from the outside is adjusted.

The display unit 40 displays the image signal adjusted through the image processing unit 30 .

In this case, the control unit 50 may always output the offset adjustment request signal to the image processing unit 30 based on the black level of the input signal, and more efficiently use the comparison unit 20 to selectively output the offset adjustment request signal. can

That is, the offset value set in the product production stage is stored in the image processing unit 30 . In addition, the offset value may be stored in a separate memory (not shown) provided in the comparator 20 or the controller 50 in addition to the inside of the image processing unit 30 .

The comparison unit 20 compares the black level detected by the black level detection unit 10 according to the control signal of the control unit 50 and the black level according to the offset value pre-stored in the image processing unit 30, An offset adjustment request signal is selectively output to the control unit 50 according to the comparison result.

That is, if the black level detected by the black level detection unit 10 is higher than the black level according to the offset value stored in the image processing unit 30 , the comparator 20 is configured to set an offset currently set in the control unit 50 . By outputting a value holding signal, the image processing unit 30 performs signal processing of the image signal without offset adjustment.

In addition, when the black level detected by the black level detection unit 10 is lower than the black level according to the offset value pre-stored in the image processing unit 30 , the comparator 20 sends the black level to the control unit 50 . An offset adjustment request signal for adjusting a currently set offset value based on the black level detected by the level detector 10 is output.

Then, the control unit 50 outputs a control signal to set an offset value according to the black level detected through the black level detection unit 10 based on the offset adjustment request signal output through the comparison unit 20 .

In addition, the image processing unit 30 adjusts a preset offset value based on the black level detected by the black level detection unit 10 according to the control signal of the control unit 50 to adjust the image signal input from the outside. to adjust

That is, when the level range of the currently input signal is lower than the currently set offset value, the dark part (lower level part) of the image signal is not expressed and is buried. By adjusting a preset offset value, an accurate color gradation may be expressed.

Therefore, the video card used for each monitor is different, and the black level of the actual input signal is slightly different. As a result, when an image whose level is lower than the initially set offset value is inputted to each monitor, the black level of the input signal is By adjusting the offset based on , it is possible to improve a phenomenon in which a black portion is buried in an actual input image signal, and a user can view the image with an optimal image quality through accurate color gradation expression.

In the method of adjusting the offset of the video display device configured as described above, an optimal offset value is first adjusted according to the level of the input signal in the production stage.

Then, the adjusted offset value is stored. The offset value stored in this way is fixed and released, and the offset value can be maintained or adjusted based on an actually currently input signal.

That is, the black level of the video signal that is actually input from the outside is detected. In other words, the lowest level is detected by analyzing the currently input image signal.

In this case, the currently applied offset value may be set and applied based on the detected black level, or the offset value may be selectively adjusted using the fixed offset value.

Next, the detected black level is compared with a black level according to an offset value stored during production of the product.

Then, as a result of the comparison, it is determined whether the detected black level is lower than the previously stored black level.

Subsequently, if the detected black level is lower than the previously stored black level as a result of the determination, a currently preset offset value is adjusted based on the detected black level. That is, an offset value capable of expressing all the level ranges of the currently input image signal is set.

Then, the image signal input from the outside is adjusted by applying the adjusted offset value.

Then, the adjusted video signal is displayed.

Meanwhile, if the detected black level is higher than the previously stored black level as a result of the determination, the previously stored offset value is maintained and the step is entered.

As such, in the video display device and the offset adjustment method, the video card used for each monitor is different, and the black level of the actual input signal is slightly different. In this case, by adjusting the offset based on the black level of the input signal, it is possible to improve the phenomenon that the black portion is buried in the actual input image signal, and the user can obtain the optimal image quality through accurate color gradation expression. You can watch the video.

Meanwhile, Korean Patent Registration No. 10-2191529 relates to a multi-projection system and method for minimizing black offset.

estimating each ITF (Intensity Transfer Function) for a plurality of projectors, calculating a threshold value of an optimal black offset for each projector using the respective ITFs, and the optimal black It provides a multi-projection method comprising the step of applying a threshold value of the offset to the image projection of each of the projectors.

Regions projected by the three projectors of the projector 1 210 , the projector 2 220 , and the projector 3 230 may be displayed as an area 1 250 , an area 2 260 , and an area 3 270 , respectively. At this time, the area projected by the projector 1 ( 210 ) and the projector 2 ( 22 ) has an overlapping area 1 ( 255 ), and the area projected by the projector 2 ( 220 ) and the projector 3 ( 230 ) is an overlapping area 2 ( 265).

In this case, the brightness of the overlapping area 1 ( 255 ) and the overlapping area 2 ( 265 ) may be made as smooth as possible by using the black offset minimization method.

The black offset minimization method includes the steps of estimating the intensity transfer function (ITF) of each projector (S310), calculating an optimal black offset threshold for each projector (S320), and determining the optimal black offset value. It is configured including the step of applying to the image to be projected by the projector (S330).

First, in the step of estimating the intensity transfer function (ITF) of each projector ( S310 ), after projecting a pattern image from each projector and photographing it with a still camera, the ITF may be estimated. The pattern image may be generated by increasing the brightness of the R, G, and B values of the projector by 15 from 0 to 255. That is, it can be generated by increasing (R,G,B)=(0,0,0), (R,G,B)=(15,15,15), (R,G,B)=(255,255,255). can

The base offset (base_offset) value can be obtained by the following method. First, all projectors simultaneously project a pure black image ((R,G,B)=(0,0,0)) on the screen, capture it with a still camera, and use the captured image to each If the average intensity value of all overlapping regions (or O) and non-overlapping regions (Non-overlapping region or NB) is calculated for the projector of , this average intensity value becomes the base_offset value. By substituting this average intensity value into base_offset, the brightness and ITF value of the image projected by the projector can be represented.

The black offset may be minimized by adjusting the brightness intensity of the left image 510 and the right image 550 .

In the step of calculating an optimal black offset threshold for each projector ( S320 ), the optimal black offset threshold is calculated using an average intensity value of all overlapping regions for each projector can be

In the step of applying the optimal black offset value to the image to be projected by the projector ( S330 ), the estimated optimal black offset value is applied to the image projection of each projector. For example, when the optimal threshold of Projector 1 is 20, the black offset is minimized by converting pixel values with RGB values of 20 or less to 20 among pixels in the non-overlapping area to be projected by Projector 1 and then projecting it to the screen. can do. For example, if there is a pixel whose RBG value is (R,G,B)=(10,10,10) among the pixels in the non-overlapping area to be projected, (R,G,B)=(20,20, 20) to minimize the black offset of the overlapping region.

The multi-projection system is configured to include a screen 610 , a projector 630 , a still camera 650 , and a processor module 670 .

The screen 610 is a screen on which an image is displayed using a plurality of projectors 630 . A plurality of images of the projector 630 may be displayed on the screen 610 in a line, and images of the projector 630 may be overlapped and displayed in some areas for a seamless and natural image display.

The projector 630 displays an image on the screen 610 . A plurality of projectors 631, 633, and 635 may project an image on one screen 610, and as shown in FIG. 2, each projector 621, 623 includes a plurality of overlapping areas 255 and 265 according to the image projection can have

The projector 630 may project a pattern image on the screen 610 to estimate an intensity transfer function (ITF) for each of the projectors 631 , 633 , and 635 .

When the pattern image is projected by the projector 630 , the still camera 650 may photograph the screen 610 on which the pattern image is projected in order to obtain the ITF of each of the projectors 631 and 633 .

When the screen 610 on which the pattern image is projected by the still camera 650 is photographed, the processor module 670 uses the brightness intensity of the photographed image to each projector 631, 633, 635 ) to estimate the ITF. In addition, the processor module 670 calculates a threshold of an optimal black offset for each of the projectors 631 , 633 , and 635 . When the threshold value of the black offset is calculated by the processor module 670, when the image is projected by each of the projectors 631, 633, 635, an image having a brightness greater than or equal to the calculated threshold is projected, so that the black offset is calculated can be minimized

By minimizing a black offset phenomenon that occurs when an image is projected on a screen using a plurality of projectors, the image can be smoothly projected on the screen.

However, since the above-described prior inventions are devices for fixing the black level by a complete software method, there is a problem in that the structure itself becomes complicated.

A problem was discovered when installing a simulator using a beam projector (BPT).

In the case of a space where low-illuminance content is implemented in an exhibition space using a beam projector (BPT), a black level phenomenon occurs due to an increase in illuminance in the overlapping area when configuring multiple projectors.

The black level phenomenon is a problem in a virtual defense-related training simulator where training is performed under conditions close to the real environment.

In museums, art galleries, and permanent exhibition halls, the black level phenomenon is becoming an issue as a major factor that hinders the immersion of visitors.

The present invention has been developed to improve this.

The motorize function mounts a motor between the connection frame plate 1130, which is the main part of the present invention, and a connection support bracket such as a bracket provided on the ceiling or a beam projector (BPT), and connects the motor to the motor shaft of the motor via a connector By connecting the frame plate 1130 or the fixed support frame plate 1135 and rotating the motor shaft of the motor by a remote controller, when the motor shaft of the motor is rotated by the controller remotely, the connection frame plate 1130 or The angle of the fixed support frame plate 1135 is rotated based on the beam projector (BPT), and the angle of the pair of upright frame plates 1120 and the pair of shields 1200 connected to the connection frame plate 1130 is also rotated This means that the angle can be easily adjusted remotely through the motorize function.

The present invention is optionally functionally linked to a commercial display device management solution.

The present invention is an improvement over current, imperfect hardware or software edge blending techniques.

The present invention produces an optimal effect at a minimum cost where a black level occurs in a space with remarkably low illuminance, such as natural light.

By setting, it works on low-light content and opens on high-light content.

In addition, the present invention can be completed as a prototype that can be manually controlled.

The present invention provides an exhibition and experience space using a beam projector (BPT).

When installing a beam projector (BPT), establish a sales process to highlight it as an essential item.

The goal of the present invention was the same concerns as overseas partners about the black level, and after the release of a prototype that has been supplemented with the motorize function, export is scheduled to proceed through consultation.

The development motivation for the product service of the present invention is as follows.

Create an environment that creates illusions like reality.

With the development of exhibition technology and virtual experience solutions, opportunities to see and feel in real life are becoming more active. It is growing as a representative convergence cultural industry based on creativity and killer content for future growth engines.

Among them, augmented reality and virtual reality technologies based on stimulation of bodily sensory organs such as immersion and sensation are widely used. give. 1 is an image showing a permanent exhibition space configuration using a beam projector (BPT) and an immersive experience exhibition using augmented reality technology.

It is leaping beyond one field of the cultural industry to become a core field of the defense industry.

With the advent of virtual training simulators capable of training like actual battles, it is growing as a core field that plays an important role in military training.

In particular, the development of the virtual training simulator business is remarkable in classes with limited training space, such as the Navy and Air Force. 2 is a mock-up 3D image of a virtual sailing training simulator image and a navy virtual training bridge.

When creating a space using a beam projector (BPT), a black level occurs.

When multiple screens are configured using multiple beam projectors (BPT), the section where the screens overlap has a higher brightness than a single screen.

At this time. The phenomenon of brightening in the overlapping section is expressed as a black level. 3 is an image showing a black level phenomenon.

The necessity of the product or service of the present invention is as follows.

When experiencing immersive content, it is necessary to remove factors that hinder the audience's immersion.

When configuring multiple screens, the black level phenomenon conveys a sense of disconnection rather than a natural continuous screen.

This hinders the immersion of the audience.

Various solutions have been proposed, but their effectiveness is insignificant.

The problem with hardware equipped with software is that it is effective when creating a dark space in the surrounding environment, and has no effect when creating a bright space in the surrounding environment.

The present invention intends to configure an environment that induces an illusion like reality.

With the development of exhibition technology and virtual experience solutions, opportunities to see and feel in real life are becoming more active. It is growing as a representative convergence cultural industry based on creativity and killer content for future growth engines.

Among them, augmented reality and virtual reality technologies based on stimulation of bodily sensory organs such as immersion and sensation are widely used. give.

It is leaping beyond one field of the cultural industry to become a core field of the defense industry.

With the advent of virtual training simulators capable of training like actual battles, it is growing as a core field that plays an important role in military training.

In particular, the development of the virtual training simulator business is remarkable in classes with limited training space, such as the Navy and Air Force.

When creating a space using a beam projector, a black level is generated.

When multiple screens are configured using multiple beam projectors (BPT), the section where the screens overlap has a higher brightness than a single screen.

In this case, the phenomenon of brightening in the overlapping section is expressed as a black level.

It is necessary to come up with a solution to solve the black level problem.

It is necessary to develop an edge blending technology to lower the brightness corresponding to the brightness in the beam projector (BPT) and to bring the colors together, and it is necessary to release the installed hardware.

Hardware equipped with software to solve the black level also needs to be released.

In the present invention, the projection angle of the lens (LZ) of the beam projector (BPT) is physically blocked to separate overlapping sections, so that the entire area can be projected with uniform brightness It was developed in consideration of the installation method.

There are only a handful of companies that even install the screen 1200 on site.

The problems of the initial method are that the installation method is difficult, the angle adjustment is impossible, and it is difficult to adjust the angle after installation.

The present invention was developed as a black offset corrector.

There is no commercialized prototype yet, and the development of the prototype is completed through the developer's numerous project experiences.

It is possible to easily cover the curved projection area by making the screen 1200 from a rubber material and mounting an angle adjustment function.

By applying the prototype to the actual business, the best effect of solving the black level phenomenon can be obtained.

A beam projector (BPT) is a device that illuminates a slide or moving image on a screen using light, and is used as a simulator in defense-related virtual training simulations, museums, art galleries, and permanent exhibition halls.

The beam projector (BPT) module is a digital light processing (DLP) method and is composed of a power supply and a laser, so that it is possible to reproduce images with DVD-level quality.

In addition, a portable imaging device called a pico projector that connects to a mobile device such as a smart phone, tablet PC, or laptop computer and emits content to be viewed as a beam project screen has also been developed.

In other words, a beam projector (BPT) is a device that projects a slide or moving image on a screen using light.

Looking at the details, the beam projector (BPT) is often used as a defense-related virtual training simulator and as a simulator in museums, art galleries, and permanent exhibition halls.

A disadvantage of the prior art is that, when installing a simulator using a beam projector (BPT), in the case of low-illuminance content, a black-level phenomenon occurs due to an increase in illuminance in the overlapping area of multiple projectors. This can cause problems in the training simulator.

In museums, art galleries, and permanent exhibition halls, it is becoming an issue as a major factor that hinders the immersion of visitors.

In the present invention considering this problem, it is implemented in the form of a shield 1200 that covers the lens LZ of the beam projector (BPT).

By physically blocking the lens (LZ) projection angle to separate overlapping sections, the entire area is projected with uniform brightness. The screen 1200 is to play such a role.

In addition, the angle adjustment function is mounted so that the curved projection area can be easily covered.

In addition, a function that can be controlled remotely through the motorize function has been added. Due to this, it is possible to improve the usability. The motorization function is a motor of the motor on the connecting frame plate 1130 or the connecting support frame plate 1131 so that the main parts of the connecting frame plate 1130 and the pair of upright frame plates 1120 can be remotely controlled remotely. It could be to combine a steering device such as an axis and remotely operate the steering device by a remote controller.

A conventional problem is that when a simulator using a beam projector (BPT) is installed, a black level phenomenon occurs due to an increase in illuminance in the overlapping area of multiple projectors in the case of content with low illuminance.

The black level phenomenon can cause problems in defense-related virtual training simulators, and is becoming an issue as a major factor hindering the immersion of visitors in museums, art galleries, and permanent exhibition halls.

The present invention was developed in the form of a lens (LZ) shield 1200 of a beam projector (BPT) to physically block the projection angle of the lens (LZ) to separate overlapping sections, so that the entire area is projected with uniform brightness.

In the present invention, the main part, the shield 1200, is made of a rubber material and has an angle adjustment function, so that it can be easily covered with respect to the curved projection area.

It is designed to provide a quick and smooth function during control by adding a function that can be controlled remotely through the motorize function.
