본 발명은 직사각형 형상의 기초렌즈로 이루어진 렌즈어레이가 구성된 깊이우선 집적 영상 디스플레이 시스템에 관한 것으로, 더욱 상세하게는 적색(r)과 녹색(g) 그리고 청색(b)의 픽셀로 이루어진 디스플레이패널에서 렌즈어레이의 기초렌즈가 직사각형 형상으로 형성됨으로써 3차원 입체 영상을 구현할 시 발생하는 색분리 현상을 제거하는 깊이우선 집적 영상 시스템을 제공하고자 하는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a depth-first integrated video display system comprising a lens array consisting of a basic lens having a rectangular shape. It is an object of the present invention to provide a depth-first integrated imaging system that eliminates color separation that occurs when a three-dimensional stereoscopic image is formed by forming a basic lens of an array.
현재, 3차원 입체 영상을 표시하기 위해 제시된 기술로는, 특수 안경에 의한 입체 화상 디스플레이, 무안경식 입체 화상 디스플레이 및 홀로그래픽(Holographic) 디스플레이 방식이 있다.Currently, technologies proposed for displaying three-dimensional stereoscopic images include stereoscopic image display, glasses-free stereoscopic image display, and holographic display method using special glasses.
이 중, 무안경식 입체 화상 디스플레이 방식은 좌우안에 해당하는 각각의 화상 앞에 세로격자 모양의 개구(Aperture)를 통하여 화상을 분리하여 관찰할 수 있게 하는 패러랙스 배리어(parallax barrier) 방식과, 반원통형 렌즈를 배열한 렌티큘러 판(lenticular plate)를 이용하는 렌티큘러(lenticular) 방식 및 파리 눈 모양의 렌즈 배열을 이용하는 집적 영상 (integral imaging) 방식으로 나눌 수 있다.Among these, the autostereoscopic three-dimensional image display method has a parallax barrier method and a semi-cylindrical lens that separate and observe an image through a vertical grid-shaped aperture in front of each image corresponding to left and right eyes. It can be divided into a lenticular (lenticular) method using a lenticular plate in which the array is arranged and an integrated imaging method using a lens array of a fly's eye shape.
이러한 무안경식 입체 영상 디스플레이 방식은 관찰 범위가 고정되어 소수 인원에 한정되지만, 특수 안경에 의한 입체 영 상 디스플레이 방식과 같이 별도의 안경을 착용하지 않아 편리하고, 홀로그래픽 디스플레이 방식에 비해 구현이 쉽기 때문에 이들 중 더욱 선호되고 있다.Such a stereoscopic image display method is limited to a small number of people due to the fixed viewing range, but it is convenient because no glasses are worn, such as a stereoscopic image display method by special glasses, and is easier to implement than a holographic display method. Among them, more preferred.
이 중에서 집적 영상 기술은 렌즈 배열을 표시 패널 전면에 배치하여 3차원 영상을 표시하기 때문에 구조적으로 간단하고, 상용화된 표시 패널을 직접적으로 사용할 수 있으며, 시야각 범위 내에서 연속적인 칼라 3차원 영상 구현이 용이하다.Among them, the integrated imaging technology displays a three-dimensional image by arranging a lens array in front of the display panel, thereby making it simple to use a commercially available display panel and achieving continuous color three-dimensional images within a viewing angle range. It is easy.
집적 영상 시스템은 표시 패널과 렌즈 배열의 배치 간격에 따라 크게 2가지 형태의 구조로 이루어진다.The integrated imaging system has two types of structures depending on the arrangement interval of the display panel and the lens array.
표시 패널과 렌즈 배열의 배치 간격을 g라고 하고, 렌즈 배열의 작은 기초렌즈가 가지는 초점거리를 f라고 하자.Let g be the distance between the display panel and the lens array, and let f be the focal length of the small elementary lens of the lens array.
이때 g=f 인 경우를 깊이우선 (depth-priority) 집적 영상이라 표현하고, g~=f 인 경우를 해상도우선 (resolution-priority) 집적 영상이라고 한다.In this case, g = f is referred to as a depth-priority integrated image, and g ~ = f is referred to as a resolution-priority integrated image.
이 두 구조는 3차원 영상의 표시 해상도와 표시 깊이감에서 차이가 있다.The two structures differ in display resolution and display depth of the 3D image.
이러한 3차원 집적 영상표시방법의 종래문헌으로는 등록특허 제0891160호에 요소 영상 압축 장치가 영역 분할 기법을 적용하여 요소 영상을 압축하는 방법에 있어서, (a) 3차원 객체로부터 렌즈 어레이를 통하여 서로 다른 시차를 가지는 요소 영상을 획득하는 단계; (b) 상기 획득된 요소 영상을 유사 상관도에 따라 복수의 유사한 영상을 가진 유사 영역으로 분할하는 단계; (c) 상기 각각의 유사 영역에 포함된 영상을 1차원 요소 영상 배열로 재배열하는 단계; 및 (d) 상기 재배열되어 생성된 1차원 요소 영상 배열을 압축하는 단계를 포함하는 영역 분할 기법을 이용한 요소 영상 압축 방법이 기재되어 있다.In the prior art of such a three-dimensional integrated image display method, a method of compressing an element image by applying an area segmentation technique to an element image compression apparatus in Patent No. 0891160, (a) from a three-dimensional object through a lens array Obtaining an element image having another parallax; (b) dividing the obtained element image into similar regions having a plurality of similar images according to the similarity of correlation; (c) rearranging the images included in each of the similar regions into a one-dimensional element image array; And (d) compressing the rearranged and generated one-dimensional element image array.

그러나 상기 종래의 집적 영상 시스템의 렌즈어레이에 사용되는 기초렌즈는 원형이기에 색분리 현상이 발생하여 제대로 된 색상정보를 보여주지 못하게 된다는 단점이 있다.However, since the elementary lens used in the lens array of the conventional integrated imaging system is circular, color separation occurs and thus it is impossible to display proper color information.

이하, 본 발명 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the depth-first integrated image display system for removing the color separation phenomenon of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 종래 기술에 따른 집적 영상 기술의 원리를 설명하는 개요도이다.1 is a schematic diagram illustrating the principle of integrated imaging technology according to the prior art.
먼저, 도 1을 참조하면, 기본적으로 3차원 물체(110)를 3차원 영상(210)으로 재생하는 원리는 3차원 물체(110)가 렌즈어레이(120)를 투시하도록 하여 요소영상(130)을 획득하는 영상획득단계(100)와 영상획득단계(100)에 의해 수집된 요소영상(100)을 다시 렌즈어레이(220)를 통해 공간상에 3차원 영상(210)로 재생하는 영상재생단계(200)로 구성된다.First, referring to FIG. 1, basically, the principle of reproducing the 3D object 110 as a 3D image 210 is to allow the 3D object 110 to see the lens array 120 so that the element image 130 may be viewed. Image reproducing step (200) of reproducing the image acquisition step 100 and the element image 100 collected by the image acquisition step 100 to obtain the three-dimensional image 210 in the space again through the lens array 220 (200) It is composed of
즉, 집적 영상 기술은 도 1에서와 같이 크게 영상획득단계(100)와 영상재생단계(200)로 나누어진다.That is, the integrated image technology is largely divided into the image acquisition step 100 and the image reproduction step 200 as shown in FIG.
영상획득단계(100)는 이미지 센서와 같은 2차원 감지기와 렌즈어레이(120)로 구성되며, 이때 3차원 물체(110)는 렌즈어레이(120) 앞에 위치한다.The image acquisition step 100 is composed of a two-dimensional sensor such as an image sensor and the lens array 120, wherein the three-dimensional object 110 is located in front of the lens array 120.
그러면 3차원 물체(110)의 다양한 영상정보들이 렌즈어레이(120)를 통과한 후 2차원 감지기에 저장된다.Then, various image information of the 3D object 110 passes through the lens array 120 and is stored in the 2D sensor.
이때 저장된 영상은 요소영상(130)으로서 3차원 영상(210)의 재생을 위해 이용된다.In this case, the stored image is used for reproducing the 3D image 210 as the element image 130.
이후 집적 영상기술의 영상재생단계(200)는 영상획득단계(100)의 역 과정으로, 액정 표시 장치와 같은 영상재생장치와 렌즈어레이(220)로 구성된다.Afterwards, the image reproducing step 200 of the integrated imaging technology is a reverse process of the image acquiring step 100, and includes an image reproducing apparatus such as a liquid crystal display and a lens array 220.
여기서, 영상획득단계(200)에서 얻은 요소영상(230)은 영상재생장치에 표시되고, 요소영상(230)의 영상정보는 렌즈어레이(220)를 통과하여 공간상에 3차원 영상(210)으로 재생되게 된다.Here, the element image 230 obtained in the image acquisition step 200 is displayed on the image reproducing apparatus, and the image information of the element image 230 passes through the lens array 220 to the 3D image 210 in space. Will be played.
실질적으로 영상획득단계(100)의 요소영상(130)과 영상재생단계(200)의 요소영상(230)은 실질적으로 동일한 것으로 단지, 영상재생단계(200)의 요소영상(230)은 영상획득단계(100)에서 획득한 요소영상(120)을 2차원 감지기에 저장되어 3차원 영상을 재생하기 위해 사용하는 것으로서 편의상 영상획득단계(100)와 영상재생단계(200)를 구분하기 위하여 다른 도면부호로 도시하였다.Subsequently, the element image 130 of the image acquisition step 100 and the element image 230 of the image reproduction step 200 are substantially the same, but the element image 230 of the image reproduction step 200 is the image acquisition step. The element image 120 acquired in (100) is stored in a 2D sensor and used to reproduce a 3D image. For convenience, the element image 120 is distinguished by using different reference numerals to distinguish the image acquisition step 100 and the image reproduction step 200. Shown.
도 2는 종래 기술에 따른 표시패널과 렌즈어레이의 배치간격에 따라 분류된 집적 영상의 시스템을 설명하는 개요도로서, 특히, 도 2a는 깊이 우선 집적 영상방식을 나타낸 개요도이고, 도 2b는 해상도 우선 집적 영상방식을 나타낸 개요도이다.FIG. 2 is a schematic diagram illustrating a system of integrated images classified according to an arrangement interval of a display panel and a lens array according to the related art. In particular, FIG. 2A is a schematic diagram illustrating a depth-first integrated image system, and FIG. It is a schematic diagram showing the video system.
이러한 집적 영상 방식은 렌즈어레이(220)와 요소영상 표시장치 사이의 거리(g)에 따라서 2종류로 구분할 수 있다.The integrated image method may be classified into two types according to the distance g between the lens array 220 and the element image display apparatus.
즉, 거리 g가 렌즈 배열(220)의 기초렌즈의 초점거리 (f)와 동일한 경우와 그렇지 않은 경우로 나눌 수 있다.That is, the distance g may be divided into a case where the distance g is the same as the focal length f of the base lens of the lens array 220 and a case where the distance g is not.
g=f인 경우는 도 2(a)와 같이 요소 영상(230)의 한 픽셀이 렌즈를 통하여 평행빔이 되어서 집적 빔이 만들어지게 된다.In the case of g = f, as shown in FIG. 2 (a), one pixel of the element image 230 becomes a parallel beam through the lens to form an integrated beam.
이 경우를 깊이 우선 집적 영상 방식이라 부르며, 3차원 영상을 표시하는 깊이 영역을 최대로 만들 수 있지만 3차원 영상(210)의 해상도가 낮은 단점이 있다.This case is called a depth-first integrated image method, and it is possible to maximize the depth area for displaying a 3D image, but has a disadvantage in that the resolution of the 3D image 210 is low.
이에 반해서 g가 f와 동일하지 않은 경우는 해상도 우선 집적 영상방식이라 부르며, 요소 영상(230)의 한 픽셀이 렌즈를 통하여 수렴빔이 되어서 집적 빔이 만들어지며, 이 경우에 3차원 영상(210)의 해상도를 증가시킬 수 있지만 깊이 영역이 급격히 줄어든다.On the other hand, when g is not equal to f, it is called a resolution-first integrated imaging method. An integrated beam is formed by converging beams of one pixel of the element image 230 through a lens, and in this case, the 3D image 210. The resolution can be increased, but the depth area is drastically reduced.
도 3은 종래 기술에 따른 적색, 녹색, 청색의 서브픽셀로 이루어진 표시 패널을 사용하는 깊이 우선 집적 영상 시스템의 구조를 설명하는 개요도이다. 3 is a schematic diagram illustrating a structure of a depth-first integrated imaging system using a display panel including red, green, and blue subpixels according to the related art.
이에, 도 3을 참조하면, 기존의 렌즈 배열을 이용한 깊이우선 집적 영상 방식에서는 하나의 점광원을 생성하는 방식에서 서브픽셀 구조의 표시패널을 사용하게 되면 점광원으로 결상되는 광선들의 세기 정보는 복원이 가능하지만, 색상 정보를 읽어버리는 문제점이 있다.Accordingly, referring to FIG. 3, in the depth-first integrated image method using a conventional lens array, when the display panel having a subpixel structure is used in a method of generating one point light source, intensity information of light rays formed as the point light source is restored. This is possible, but there is a problem of reading color information.
도 3에서 보여지듯이 점광원을 만드는데, 다양한 칼라정보가 모이게 된다.As shown in Figure 3 to create a point light source, various color information is collected.
이 점광원들이 관측자에게 관측될 때에는 제대로된 색상정보를 보여주지 못하게 된다. 이러한 문제가 색분리 현상의 주요 원인이다.When these point sources are observed by the observer, they do not show the correct color information. This problem is a major cause of color separation.
따라서, 올바른 3차원 영상을 구현하기에는 어려운 문제점이 있다.Therefore, there is a problem that it is difficult to implement a correct three-dimensional image.
도 4는 본 발명의 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템을 나타낸 개략도이다.Figure 4 is a schematic diagram showing a depth-first integrated image display system for removing the color separation phenomenon of the present invention.
도 4에 도시된 바와 같이 본 발명의 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템은 적색(r)과 녹색(g) 그리고 청색(b)의 서브픽셀로 이루어진 디스플레이패널(250)과, 상기 디스플레이패널(250)의 배면에 배치되어 디스플레이패널(250) 측으로 빛을 제공하는 백라이트 유닛(260)과, 상기 디스플레이패널(250)의 전면에 배치되어 디스플레이패널(250)의 서브픽셀을 확대하여 통과시키는 렌즈어레이(220)로 구성되는 것으로, 상기 렌즈어레이(220)는 수직단면이 직사각형 형상인 기초렌즈가 상하좌우로 배열되어 있는 것이 특징이다.As shown in FIG. 4, the depth-first integrated image display system for removing color separation of the present invention includes a display panel 250 including red (r), green (g), and blue (b) subpixels. A backlight unit 260 disposed on a rear surface of the display panel 250 to provide light toward the display panel 250 and an enlarged subpixel of the display panel 250 disposed on the front surface of the display panel 250. It is composed of a lens array 220, the lens array 220 is characterized in that the vertical lens is arranged in a vertical cross-section of the base lens in the vertical, vertical, left and right.
즉, 디스플레이패널(250)의 영상은 기본적으로 적색(r)과 녹색(g) 그리고 청색(b)으로 이루어져 있으며, 적색(r)과 녹색(g) 그리고 청색(b)을 rgb라 부르며, 본 발명에서는 이러한 rgb칼라에 해당하는 픽셀을 서브픽셀로 부르기로 한다.That is, the image of the display panel 250 basically consists of red (r), green (g) and blue (b), and red (r), green (g) and blue (b) are called rgb. In the present invention, the pixel corresponding to the rgb color is called a subpixel.
그리고 상기 디스플레이패널(250)의 배면에는 디스플레이패널(250)에 빛을 제공하는 광원으로서 백라이트 유닛(260)이 위치하고 있으며, 상기 디스플레이패널(250)의 전면에 배치되어 디스플레이패널(250)의 서브픽셀을 확대하여 통과시키는 렌즈어레이(220)로 구성된다.In addition, a backlight unit 260 is positioned on a rear surface of the display panel 250 as a light source that provides light to the display panel 250. The backlight unit 260 is disposed in front of the display panel 250 and is a subpixel of the display panel 250. It consists of a lens array 220 to pass through.
특히, 본 발명에서 상기 렌즈어레이(200)는 수직단면이 직사각형 형상인 기초렌즈가 상하좌우로 배열되어 있다.In particular, in the present invention, the lens array 200 has a basic lens having a vertical cross section of a rectangular shape arranged up, down, left, and right.
일반적으로 상기 기초렌즈는 볼록렌즈이다.In general, the elementary lens is a convex lens.
도 5는 본 발명의 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템의 디스플레이패널과 서브픽셀 확대표시용 렌즈어레이 구조를 나타낸 개요도이다.FIG. 5 is a schematic diagram illustrating a structure of a display panel and a lens array for subpixel enlargement display of a depth-first integrated image display system which eliminates color separation.
한편, 도 5에 도시된 바와 같이 기존의 렌즈어레이(220)의 구조에서는 기초렌즈가 동일한 모양의 원형이나 사각형 모양과는 달리 수직단면이 직사각형 형상의 구조를 가지도록 제작된다.On the other hand, in the structure of the existing lens array 220, as shown in Figure 5, unlike the circular or square shape of the same shape of the primary lens is made so that the vertical cross-section has a rectangular structure.
그리고 이렇게 제작된 직사각형 기초렌즈 3개를 하나의 단위로 구성한다.The three rectangular basic lenses thus manufactured are constructed as one unit.
기초렌즈 3개를 하나의 단위로 한 것을 단위렌즈라 일컬으며, 이러한 단위렌즈로 구성된 렌즈어레이(220)를 서브픽셀 구조의 디스플레이패널(250)에 위에 올려둔다.A unit lens having three basic lenses as one unit is called a unit lens, and a lens array 220 composed of such unit lenses is placed on the display panel 250 having a subpixel structure.
도 6은 본 발명의 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템의 서브픽셀 확대용 렌즈어레이와 디스플레이패널 사이의 위치 관계를 설명하는 개요도이다.FIG. 6 is a schematic diagram illustrating a positional relationship between a subpixel magnifying lens array and a display panel of a depth-first integrated image display system that eliminates color separation.
도 6에서 도시되어 있는 바와 같이 렌즈어레이(220)와 디스플레이패널(250) 사이의 거리는 렌즈어레이(220)의 기초렌즈의 초점거리와 같게 한다.As shown in FIG. 6, the distance between the lens array 220 and the display panel 250 is equal to the focal length of the base lens of the lens array 220.
그러면 디스플레이패널(250)을 통과하는 빔(광선)은 각각의 기초렌즈를 통과하여 평행빔으로 만들어지게 된다.Then, the beams (rays) passing through the display panel 250 pass through the respective basic lenses to form parallel beams.
앞서 기재된 바와 같이, 본 발명에서 사용하는 단위렌즈는 작은 3개의 기초렌즈로 구성되어 있으며, 각각의 기초렌즈를 통하여 서로 다른 색깔의 평행빔이 만들어지도록 한다.As described above, the unit lens used in the present invention is composed of three small base lenses, and the parallel beams of different colors are made through each base lens.
도 7은 단위렌즈와 디스플레이패널의 서브픽셀 사이의 관계를 보여주는 개요도이다.7 is a schematic diagram illustrating a relationship between a unit lens and a subpixel of a display panel.
도 7은 1차원적으로 4개의 서브픽셀과 하나의 기초렌즈가 매칭이 되는 예를 보여 준다.7 shows an example in which four subpixels and one elementary lens are matched in one dimension.
이것은 도 7b에서 집적영상 방식에서 4픽셀의 요소영상(12subpixel)을 사용하는 경우와 동일하다.This is the same as the case of using a 4 pixel element image (12 subpixel) in the integrated image method in FIG.
본 발명에서의 방식에서 3차원 영상을 표시하기 위해서는 도 7(a)와 같이 rgb칼라의 위치를 바꾸어야 한다.In order to display a 3D image according to the present invention, the position of the rgb color should be changed as shown in FIG.
도 8은 기존의 요소영상에서 본 발명 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템의 새로운 요소영상으로 교환하는 개요도이다.FIG. 8 is a schematic diagram of exchanging a new element image of a depth-first integrated image display system to remove the color separation phenomenon of the present invention from an existing element image.
픽셀을 교환하는 원리는 다음과 같다.The principle of swapping pixels is as follows.
단위렌즈의 3개의 기초렌즈는 rgb픽셀을 나누어서 배치하는 것이다.The three elementary lenses of the unit lens are arranged by dividing the rgb pixels.
N개의 픽셀 (3N 서브픽셀)에 대해서 변환을 한다고 하면 k번째 픽셀에 대해서는 (k, k+N, k+2N)의 서브픽셀 위치로 변환이 일어나며, 여기서 rgb칼라 정보에 맞추어서 교환 배치를 하면 된다.If N pixels (3N subpixels) are converted, the k-th pixel is converted into a subpixel position of (k, k + N, k + 2N), and the swap arrangement is performed according to the rgb color information. .
예를 들면 N=4인 요소영상 픽셀(12 서브픽셀)에 대해서는 다음과 같다.For example, an element image pixel (12 subpixels) of N = 4 is as follows.
k=1이면 1, 5, 9번째의 서브픽셀 위치와 연결이 되고, 칼라에 맞추어서 재 배치하게 된다.If k = 1, it is connected to the 1st, 5th, and 9th subpixel positions, and it is rearranged according to the color.
그러면 1r은 1번째에, 1g는 5번째 픽셀에, 1b는 9번째 픽셀로 변환된다.Then 1r is converted to the first, 1g to the fifth pixel, and 1b to the ninth pixel.
K=2이면 2, 6, 10번째의 서브픽셀 위치와 연결이 되고, 칼라위치를 맞추어서 재배치하면 2r는 10번째에, 2g는 2번째에, 2b는 6번째로 연결된다.If K = 2, the second, sixth, and tenth subpixel positions are connected, and when the color positions are rearranged, 2r is connected to the tenth, 2g to the second, and 2b to the sixth.
K=3와 k=4d인 경우에도 동일한 원리를 적용하여 변환할 수 있다.Even when K = 3 and k = 4d, the same principle can be applied for conversion.
도 9는 본 발명 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템에서 2차원 요소영상에 대한 영상 표시의 예를 보여주는 개요도이다.FIG. 9 is a schematic diagram illustrating an example of an image display of a 2D element image in a depth-first integrated image display system that eliminates color separation.
도 9에 도시된 바와 같이 서브픽셀 확대용 렌즈어레이(220)를 디스플레이패널(250)에 올려지면, 관측자는 렌즈어레이(220)를 통해서 디스플레이패널(250)의 서브픽셀 중에서 하나의 서브픽셀을 확대해서 보여준다.As shown in FIG. 9, when the subpixel magnifying lens array 220 is mounted on the display panel 250, the viewer enlarges one subpixel among the subpixels of the display panel 250 through the lens array 220. Show it.
도 9(b)에서와 같이 관측자는 근거리에서는 rgb형태의 영상을 보게 된다.As shown in FIG. 9 (b), the observer sees an image of rgb type at a short range.
이 구조는 마치 서브픽셀 구조의 디스플레이패널(250)을 각각 확대한 형태와 동일하다.This structure is similar to the form in which each of the display panels 250 of the subpixel structure is enlarged.
그러면 실제 표시하고자 하는 영상으로 관측자는 관측이 가능하다.Then, the viewer can observe the image to be displayed.
도 10은 기존의 방법에서 3차원 영상의 결상 원리를 나타낸 개요도이다.10 is a schematic diagram showing the principle of imaging of a three-dimensional image in the conventional method.
렌즈어레이(220)를 통하여 결상되는 점영상을 관측자가 관측할 때 관측하는 점결상 영상의 색깔정보를 잃어버리게 되는 문제점이 있고, 이것이 칼라 색분산의 기본적인 원인이다.When the observer observes the point image formed through the lens array 220, there is a problem that the color information of the point image to be observed is lost, which is the basic cause of color color dispersion.
도 11은 본 발명 색분리 현상을 제거하는 깊이우선 집적 영상 디스플레이 시스템에서 3차원 영상의 결상원리를 나타낸 개요도이다.FIG. 11 is a schematic diagram illustrating an imaging principle of a 3D image in a depth-first integrated image display system that eliminates color separation.
기존의 방법과는 다르게 하나의 점결상 영상을 rgb의 칼라성분으로 분리하여 구성하고, 각각의 칼라정보에 대해서 결상의 원리를 적용하는 것이다.Unlike the existing method, one point image is divided into color components of rgb, and the imaging principle is applied to each color information.
예로 빨간색에 대한 점결상을 영상을 만든다고 하면, 디스플레이패널(250)에서 r의 서브픽셀과 연결되는 픽셀들과의 기하광학적 구조를 연결하여 결상을 해석한다.For example, if an image of a point image of red is made, the image is interpreted by connecting the geometric optical structure of the pixels connected to the subpixel of r in the display panel 250.
이 경우에는 관측자는 색깔정보를 잃어버리지 않고 r정보의 세기만을 표시한다.In this case, the observer only displays the intensity of the r information without losing color information.
g와 b에 대한 결상원리도 동일하게 적용이 가능하다.The same principle applies to g and b imaging.
관측자는 rgb를 결합하여 관측함으로써 제대로 표시된 칼라와 빛의 세기를 구현할 수 있다.The observer can combine rgb to observe the color and light intensity displayed properly.
또한, 영상재생단계(200)에서 3차원 영상을 디스플레이할 때, 렌즈어레이(220)의 전면에 마스크 패널을 설치하여 요소영상(230)이 렌즈어레이(220)와 마스크 패널을 통과하도록 함으로써 선명한 3차원 영상이 디스플레이될 수 있도록 하였다.In addition, when displaying a three-dimensional image in the image playback step 200, by installing a mask panel on the front of the lens array 220, the element image 230 passes through the lens array 220 and the mask panel to make clear 3 Dimensional images can be displayed.
한편, 상기 마스크 패널은 요소영상이 통과되지 않는 차단영역과 요소영상이 통과하는 투과영역으로 구성되어 있되, 상기 차단영역과 투과영역이 시간에 따라 순차적으로 위치가 교번되도록 함으로써 더욱 선명한 3차원 영상이 디스플레이될 수 있도록 하였다.On the other hand, the mask panel is composed of a blocking region where the element image does not pass and a transmission region through which the element image passes, and the cut area and the transmissive region are alternately positioned with time in order to provide a clearer 3D image. It can be displayed.
그리고 디스플레이패널이 흰색으로 표시됨과 동시에 마스크 패널에 2차원 영상이 표시되면, 공간상에는 3차원 영상이 디스플레이되지 않고 2차원 영상이 디스플레이되는 되는 것, 상기 디스플레이패널의 일부 영역에만 흰색으로 표시되면, 상기 디스플레이패널의 흰색 영역에 대응되는 마스크 패널의 영역에는 2차원 영상이 디스플레이되는 것, 흰색으로 표시되지 않는 상기 디스플레이장치패널의 나머지 영역에서는 요소영상이 렌즈어레이와 마스크 패널을 통과하여 공간상에 3차원 영상이 디스플레이되는 방법을 선택적으로 구현할 수 있다.When the display panel is displayed in white and the 2D image is displayed on the mask panel, the 2D image is displayed without displaying the 3D image in space, and when the display panel is displayed in white only in a portion of the display panel, Two-dimensional image is displayed in the area of the mask panel corresponding to the white area of the display panel. In the remaining area of the display device panel which is not displayed in white, the element image passes through the lens array and the mask panel and is three-dimensional in space. A method of displaying an image may be selectively implemented.
상술한 바와 같이, 본 발명은 렌즈어레이의 기초렌즈가 직사각형 형상으로 형성됨으로써 3차원 입체 영상을 구현할 시 발생하는 색분리 현상이 제거되며, 이로 인해 선명한 화질의 3차원 영상이 제공되어 더욱더 입체감 있는 3차원 영상을 즐길 수 있다는 등의 현저한 효과가 있다.As described above, the present invention eliminates the color separation that occurs when the three-dimensional stereoscopic image is realized by forming the basic lens of the lens array in a rectangular shape, thereby providing a three-dimensional image with clear image quality, thereby providing a more three-dimensional effect. There is a remarkable effect, such as being able to enjoy 3D images.
