摄象装置系统camera system

技术领域technical field

本发明涉及用于对被摄影物进行摄影的静止画面或动画画面用的摄影装置系统。The present invention relates to a photographing device system for photographing a still picture or a moving picture of a subject.

背景技术Background technique

在普通照相机或视频摄影机等装置中使用摄象装置,该装置使用CCD、CMOS或人工网膜芯片的固体摄象器件作为摄象器件。最近将这些器件加到以所述那样的摄影为主的单独的装置中,也考虑可以将它们装载或连接到个人计算机、便携式信息终端和便携式电话等所谓移动信息装置中的摄象装置,摄象装置的小型化在考虑这些信息装置性质的场合,这些器件是极其重要的因素。An imaging device is used in devices such as ordinary cameras or video cameras, and the device uses a solid-state imaging device of a CCD, CMOS or artificial omentum chip as an imaging device. Recently, these devices are added to independent devices mainly for photography as described above, and it is also considered that they can be loaded or connected to imaging devices in so-called mobile information devices such as personal computers, portable information terminals, and cellular phones. These devices are extremely important factors in the miniaturization of image devices when considering the properties of these information devices.

图14是在例如特开平10-227962号公报或特开平10-293236号公报等中被公布的以往的固体摄象装置的构成图。在图14中,101是被摄影物,102是用来在摄象器件表面使被摄影物成像的成像透镜,104是光电变换器件以矩阵形状排列的摄象器件,被摄影物的像105由成像透镜成像,光电变换器件用来根据由被摄影物的像所形成的光强度变换成电信号,104是设置透镜的镜筒。此处为简单起见,省略了低通滤波器和红外滤波器等滤波器种类。14 is a configuration diagram of a conventional solid-state imaging device disclosed in, for example, JP-A-10-227962 or JP-A-10-293236. In Fig. 14, 101 is an object to be photographed, 102 is an imaging lens for imaging the object to be imaged on the surface of the imaging device, and 104 is an imaging device in which photoelectric conversion devices are arranged in a matrix shape, and the image of the object to be photographed is represented by 105. The imaging lens forms an image, and the photoelectric conversion device is used to convert the light intensity formed by the image of the object into an electrical signal, and 104 is a lens barrel for setting the lens. For simplicity, filter types such as low-pass filter and infrared filter are omitted here.

其次,说明有关动作。由被摄影物101反射或从被摄影物产生的光线通过成像透镜102在摄影器件103上使被摄影物的像105成像。光电器件103配置了多个光电变换器件,并检测一个光电变换器件到达某个空间部分的光强度后变换成相当于光强度的电信号,而从这些电信号和光电变换器件的配置位置信息把在整个摄象器件上被成像的被摄影物的像105能够在例如显示装置等装置上再生。Next, the relevant actions are described. The light reflected by the subject 101 or generated from the subject passes through the imaging lens 102 to form an image 105 of the subject on the imaging device 103 . The photoelectric device 103 is equipped with a plurality of photoelectric conversion devices, and after detecting the light intensity of a photoelectric conversion device reaching a certain space part, it is converted into an electrical signal equivalent to the light intensity, and from these electrical signals and the configuration position information of the photoelectric conversion device, the The image 105 of the subject formed on the entire imaging device can be reproduced on a device such as a display device.

在摄象装置中所使用的光学系统的特性主要通过亮度和画面视角来表示。亮度表示在将光圈打开时能够摄影的被摄影物的亮度的大致标准,通常用F(焦距)数字表示。现在,在假定透镜的有效直径为a,透镜的焦点距离为f的场合,并用F数字=f/a给出。另外,画面视角表示通过摄象装置能够摄影的被摄影物的区域,即摄象器件能够通过透镜可成像的区域。例如,摄象器件表面的尺寸若假定对角线b=1/2英寸(12.7mm),形状若假定和普通的电视画面相同,垂直/水平的长度比为3∶4,若假定摄象器件的垂直长度为(3/5)×b、水平长度为(4/5)×b,透镜和摄象器件的距离为L(在无限远焦点的场合大致等于f),那么,画面视角用等式The characteristics of an optical system used in an imaging device are mainly expressed by brightness and a screen angle of view. Brightness represents a rough standard of the brightness of a subject that can be photographed when the aperture is opened, and is usually represented by an F (focal length) number. Now, assuming that the effective diameter of the lens is a, and the focal length of the lens is f, it is given by F number = f/a. In addition, the screen angle of view represents the area of the subject that can be photographed by the imaging device, that is, the area that can be imaged by the imaging device through the lens. For example, if the size of the surface of the imaging device assumes that the diagonal line b=1/2 inch (12.7mm), if the shape is assumed to be the same as that of an ordinary TV screen, and the vertical/horizontal length ratio is 3:4, if the imaging device is assumed The vertical length is (3/5) × b, the horizontal length is (4/5) × b, and the distance between the lens and the imaging device is L (approximately equal to f in the case of infinity focus), then the angle of view of the picture is equal to Mode

垂直画面视角=2×tan-1(((3/5)×b/2)/L)…(1)Vertical screen viewing angle = 2×tan-1(((3/5)×b/2)/L)…(1)

水平画面视角=2×tan-1(((4/5)×b/2)/L)…(2)Horizontal picture viewing angle = 2×tan-1(((4/5)×b/2)/L)…(2)

给出。give.

现在,作为标准的摄象装置的成像透镜,假定F数字=2.8,水平画面视角为40°,根据所述的等式求出f=13.96mm,a=4.98mm。因此,透镜和摄象器件的距离,即摄象装置的厚度约为14mm。另一方面,被摄影物的像分辨率由在摄象器件中被配置成矩阵形状的图象元素(像素)间距来决定,在所述1/2英寸摄象器件的场合,如果想要得到水平画面的尺寸为10.16mm的VGA(640像素×480像素:图3中所示的摄象器件表面的大小)的图象,那么,像素间距为15.9微米左右。Now, as an imaging lens of a standard imaging device, it is assumed that the F number=2.8 and the horizontal screen angle of view is 40°, and f=13.96mm and a=4.98mm are obtained according to the above equation. Therefore, the distance between the lens and the imaging device, that is, the thickness of the imaging device is about 14 mm. On the other hand, the image resolution of the subject is determined by the pitch of picture elements (pixels) arranged in a matrix in the imaging device. In the case of the 1/2-inch imaging device, if one wants to obtain If the horizontal screen size is 10.16mm VGA (640 pixels x 480 pixels: the surface size of the imaging device shown in Fig. 3) image, then the pixel pitch is about 15.9 microns.

现在,图14表示以往摄象装置的分辨率的图。在图14中,X是成像透镜的位置,Y是成像透镜的光轴。箭头表示图象,该图象大小为200像素。为简单起见,若假定只着眼于水平方向的分辨率,并且在离透镜698mm的位置有水平部分的大小为159mm的被摄影物,那么,由于从透镜直到摄象器件表面的距离L=13.96mm,因此,被摄影物的像被缩小为被摄影物的大小的50分之一(13.96÷698),并在摄象器件表面形成。因此,被摄影物的像变为3.18mm,由于分辨率通过15.9微米间距的摄象器件读取3.18mm的像,因此在水平方向能以200个像素读取。Now, FIG. 14 is a diagram showing the resolution of a conventional imaging device. In FIG. 14, X is the position of the imaging lens, and Y is the optical axis of the imaging lens. Arrows indicate images, which are 200 pixels in size. For the sake of simplicity, if it is assumed that we only pay attention to the resolution in the horizontal direction, and there is a subject with a size of 159mm in the horizontal part at a position 698mm away from the lens, then, since the distance L=13.96mm from the lens to the surface of the imaging device , Therefore, the image of the subject is reduced to one-fiftieth of the size of the subject (13.96÷698), and is formed on the surface of the imaging device. Therefore, the image of the subject becomes 3.18 mm, and since the image of 3.18 mm is read by the imaging device with a pitch of 15.9 microns, it can be read with 200 pixels in the horizontal direction.

由于以往的摄象装置如所述那样被构成,若想要获得标准的亮度、画面视角的图象,必须增大成像透镜和摄象器件的受光表面之间的距离,为此,摄象器件厚度被变厚。另外,在将以往的摄象装置装入电子装置,尤其是装入叫做便携式电话机,便携式摄象机,手表和便携式信息终端的电子装置中的场合,由于摄象装置的厚度增大,因此为要装入到这些便携用的电子装置中,要增大尺寸并且连接起来,还必须搬运大的摄象装置。Because the prior imaging device is constituted as described, if want to obtain the image of standard brightness, screen angle of view, must increase the distance between the light-receiving surface of imaging lens and imaging device, for this reason, imaging device Thickness is thickened. In addition, when a conventional imaging device is incorporated into an electronic device, especially an electronic device called a cellular phone, a camcorder, a watch, and a portable information terminal, since the thickness of the imaging device increases, the In order to be incorporated into these portable electronic devices, it is necessary to increase the size and connect them, and it is necessary to carry a large imaging device.

具体实施方式Detailed ways

实施例1Example 1

以下说明关于本发明的实施例1。图1(a)是根据本发明的实施例1的摄象装置的构成图,以及图1(b)是摄象装置的系统图。在图1(a)中,为了在单个摄象器件表面上使被摄影物的像成像,1是被设置在各个镜筒4中的多个成像透镜,在垂直方向和水平方向上各2个,共计有2×2=4个。4个成像透镜1分别单独地构成4个透镜系统。Embodiment 1 of the present invention will be described below. Fig. 1(a) is a configuration diagram of an imaging device according to Embodiment 1 of the present invention, and Fig. 1(b) is a system diagram of the imaging device. In Fig. 1 (a), in order to make the image imaging of the subject on the surface of a single imaging device, 1 is a plurality of imaging lenses arranged in each lens barrel 4, each 2 in the vertical direction and the horizontal direction , there are 2×2=4 in total. The four imaging lenses 1 constitute four lens systems individually.

Y1和Y2表示成像透镜1的光轴。101是被摄影物,103是具有被配置成矩阵状的光电变换器件的摄象器件,2是在单独的摄象器件103的受光表面上被成像的4个被摄影物的像,在图中只能看到眼前的2个。61是摄象装置。Y1 and Y2 represent the optical axis of the imaging lens 1 . 101 is an object to be photographed, 103 is an imaging device having photoelectric conversion devices arranged in a matrix, and 2 is an image of four objects to be imaged on the light-receiving surface of a single imaging device 103. In the figure I can only see 2 in front of me. 61 is an imaging device.

成像透镜1作为材料用丙烯基树脂、聚碳酸脂树脂或者非结晶性聚(链)烯树脂等透光树脂或玻璃等无机透光性材料形成,用喷射成形、热硬化、光硬化、加压成形或蚀刻等方法通过改变表面形状使其保持透镜效果。The imaging lens 1 is formed of light-transmitting resins such as acrylic resins, polycarbonate resins, or non-crystalline poly(alkene) resins, or inorganic light-transmitting materials such as glass. Methods such as shaping or etching work by changing the shape of the surface so that it retains the lens effect.

接着,对动作进行说明。由被摄影物101反射或从被摄影物101产生的光线分别通过4个成像透镜1在摄象器件103的受光面上成像。此处,4个成像透镜1分别在摄象器件103的受光面上形成相似的被摄影物的像2。在摄象器件103的受光面上例如配置CCD等多个光电变换器件,一个光电变换器件检测到达某个空间部分的光强度,并变换成相当于光强度的电信号。如果将这些电信号和光电变换器件的配置位置信息分离,就能在单独的整个摄象器件上再生被成像的4个被摄影物的像2,再将它们再次合成形成一个被摄影物的像。Next, the operation will be described. The light rays reflected by the object 101 or generated by the object 101 respectively pass through the four imaging lenses 1 and form images on the light-receiving surface of the imaging device 103 . Here, the four imaging lenses 1 form similar images 2 of the subject on the light-receiving surface of the imaging device 103 . On the light-receiving surface of the imaging device 103, for example, a plurality of photoelectric conversion devices such as CCD are disposed, and one photoelectric conversion device detects the light intensity reaching a certain space and converts it into an electrical signal corresponding to the light intensity. If these electrical signals are separated from the configuration position information of the photoelectric conversion device, the 4 images of the imaged object can be reproduced on a single entire imaging device, and then they are synthesized again to form an image of the object. .

在图1(b)中,61是具有在图1(a)中所示那样的成像透镜、并在摄象器件103的受光面上形成4个被摄影物的像2的摄象装置,62是用来由4个被摄影物的像2再生一个被摄影物的像的信号配置变换部分。该信号配置变换部分62作为众所周知的电路由帧存储器等存储器器件、用来在和摄象器件中间读出电信号的控制电路、在控制从存储器器件读出顺序的同时读出电信号的控制电路等构成。在该构成中,叙述关于被摄影物的像的形成。构成所述摄象器件的受光面的一个光电变换器件的电信号强度按照它的光电变换器件的配置位置顺序(例如从被配置在最上面的水平线上的光电变换器件的左端起按照图2所示的像素n1,1、…nx,1、n1,2、…、nx,2、…、…、n1,y、…、nx,y的顺序)读出。这些光电变换器件的电信号应该在信号配置变换部分一次写入存储器器件,再次从存储器器件读出,经由图象处理装置108在图像显示装置109中被显示,但在往该存储器写入以及读出时要按照被摄影物的像的个数、位置重新配置电信号数据,即按照n1,1、n(x/2)+1,1、n1,(y/2)+1、n(x/2)+1,(y/2)+1、n2,1、n(x/2)+2,1、n2,(y/2)+1、n(x/2)+2,(y/2)+1、……nx/2,1、nx,1、nx/2,(y/2)+1、nx,(y/2)+1、n1,2、n(x/2)+2、n1,(y/2)+2、n(x/2)+1,(y/2)+2、……nx/2,y/2、nx,y/2、nx/2,y、nx,y那样顺序重新配置各像素,通过按这个顺序读出,变换成一个被摄影物的像后送到图象处理装置108,因此在图象显示装置109映出一个被摄影物的像。根据以上的构成,本摄象装置系统即使用多个成像透镜在摄象器件的受光面上形成多个被摄影物的像,也具有通过信号配置变换部分能够合成一个被摄影物的像的特征。In Fig. 1 (b), 61 is to have the imaging lens as shown in Fig. 1 (a), and forms the imaging device of 4 photographed objects like 2 on the light-receiving surface of imaging device 103, 62 It is a signal arrangement conversion part to reproduce the image of one subject from image 2 of four subjects. The signal configuration conversion section 62 is a well-known circuit composed of a memory device such as a frame memory, a control circuit for reading an electrical signal between an imaging device, and a control circuit for reading an electrical signal while controlling the order of reading from the memory device. and so on. In this configuration, the formation of an image of a subject is described. The electrical signal intensity of a photoelectric conversion device constituting the light-receiving surface of the imaging device is in accordance with the arrangement position sequence of its photoelectric conversion devices (for example, from the left end of the photoelectric conversion device arranged on the uppermost horizontal line according to Fig. 2 The pixels n 1,1 , . . . n x,1 , n 1,2 , . . . , n x , 2 , . The electrical signals of these photoelectric conversion devices should be written into the memory device once in the signal configuration conversion part, read from the memory device again, and displayed on the image display device 109 via the image processing device 108, but when writing and reading to the memory When outputting, the electrical signal data should be reconfigured according to the number and position of the images of the subject, that is, according to n 1, 1 , n (x/2)+1, 1 , n 1, (y/2)+ 1, n (x/2)+1, (y/2)+1 , n2, 1 , n (x/2)+2, 1, n 2, (y/2)+1 , n (x/2)+2 ,(y/2)+1 ,...n x/2,1 ,n x,1 ,n x/2,(y/2)+1 ,n x,(y/2)+1 ,n 1, 2 , n (x/2)+2 , n 1, (y/2)+2 , n (x/2)+1, (y/2)+2 , ... n x/2, y/2 , n x, y/2 , n x/2, y , n x, y sequentially rearrange each pixel, read out in this order, convert it into an image of the subject and send it to the image processing device 108, therefore On the image display device 109, an image of a subject is displayed. According to the above structure, even if the image pickup system uses a plurality of imaging lenses to form images of a plurality of objects on the light receiving surface of the image pickup device, it also has the feature of being able to synthesize images of one object through the signal configuration conversion part. .

在摄象装置中使用的光学系统的特性已被叙述,它们主要由亮度和画面视角表示。亮度在光圈打开时表示能够摄影的被摄影物的亮度的大致标准,通常用F数字表示,若假定画面视角的摄象器件的尺寸为对角线b,其形状和普通的电视画面一样,垂直和水平的长度比为3∶4,那么,用(1)式和(2)式给出的画面视角也已经叙述。The characteristics of the optical system used in the imaging device have been described, and they are mainly represented by the luminance and the viewing angle of the picture. When the aperture is open, it indicates the approximate standard of the brightness of the object that can be photographed. It is usually expressed by F number. If the size of the imaging device assuming the viewing angle of the screen is diagonal b, its shape is the same as that of an ordinary TV screen, vertical The ratio of the length to the horizontal is 3:4, then, the angle of view of the picture given by formula (1) and formula (2) has also been described.

现在,用多个成像透镜实现F数字=2.8、水平画面视角=40°的摄象装置。在图1的构成中,假定在垂直和水平方向将成像透镜的个数设置为各2个,共计2×2=4个,在摄象器件103的受光面上形成4个被摄影物的像。即在等分为纵向2个、横向2个的各受光面上各自形成一个被摄影物的像。为此,由于在对角线为b/2的摄象器件的受光面上形成一个被摄影物的像,因此,为了从所述式子得到水平画面视角40°,以及为了得到L=6.98mm、F数字=2.8,就要求出a=2.49mm。因此,成像透镜和摄象器件的距离,即摄象装置的厚度为7mm,和用一个成像透镜构成的以往摄象装置比较变成一半,能够实现薄型化。Currently, an imaging device with F number = 2.8 and horizontal screen angle of view = 40° is realized by a plurality of imaging lenses. In the composition of Fig. 1, assume that the number of imaging lenses is set to 2 each in the vertical and horizontal directions, a total of 2*2=4, and 4 images of the subject are formed on the light-receiving surface of the imaging device 103 . That is, one image of the subject is formed on each light-receiving surface equally divided into two vertically and two horizontally. For this reason, since the image of an object to be photographed is formed on the light-receiving surface of the imaging device whose diagonal line is b/2, in order to obtain the horizontal picture angle of view of 40° from the formula, and in order to obtain L=6.98mm , F number=2.8, just require a=2.49mm. Therefore, the distance between the imaging lens and the imaging device, that is, the thickness of the imaging device is 7 mm, which is half that of a conventional imaging device constituted by a single imaging lens, enabling thinning.

另一方面,和以往的摄象器件的情况一样,若考虑被摄影物的像的分辨率,因为对一个被摄影物的像的水平画面的尺寸为5.08mm,如果像素间距为15.9微米左右,则分辨率就为320×240,被摄影物的像的分辨率为VGA的1/2。例如,若假定在离成像透镜698mm的位置有水平部分大小为159mm的被摄影物,那么,因为从成像透镜到摄象器件的受光面的距离L=6.98,所以,用一个成像透镜形成的被摄影物的像被缩小成被摄影物的大小的100分之1(6.98÷698),并在摄象器件的受光面上被形成。因此,由于被摄影物的像成为1.59mm,并由15.9微米间距的摄象器件读取1.59mm的像,所以分辨率就会在水平方向能用100个像素读取。同样地,即使用其它的成像透镜形成被摄影物的像,分辨率各自就会在水平方向用100个像素读取同样的被摄影物的像。On the other hand, as in the case of conventional imaging devices, if the resolution of the image of the object is considered, because the size of the horizontal frame of an image of the object is 5.08 mm, if the pixel pitch is about 15.9 microns, Then the resolution is 320×240, and the resolution of the subject image is 1/2 of VGA. For example, if it is assumed that there is an object with a horizontal portion size of 159 mm at a position 698 mm away from the imaging lens, then, because the distance L=6.98 from the imaging lens to the light-receiving surface of the imaging device, the object formed by an imaging lens The image of the photographed object is reduced to 1/100 of the size of the photographed object (6.98÷698), and is formed on the light-receiving surface of the imaging device. Therefore, since the image of the subject is 1.59 mm and the image of 1.59 mm is read by the imaging device with a pitch of 15.9 microns, the resolution can be read with 100 pixels in the horizontal direction. Similarly, even if an image of a subject is formed using another imaging lens, the same image of the subject is read with 100 pixels in the horizontal direction for each resolution.

涉及本发明的实施例1的4个成像透镜、摄象器件以及与被摄影物的关系在图3和图4(a)、(b)中示出。图3示出像素大小为640像素×480像素的摄象器件表面。X1~X4是成像透镜的位置,Y1~Y4是成像透镜的光轴。在图4(a)中表示用水平面(图3的A-A线)截断的断面图。若假定在2个同一水平面上的透镜的光轴间的距离为2P、从透镜到受光面的距离为L、从被摄影物到透镜的距离为LO,那么,用二个透镜成像的被摄影物的像的中心通过简单作图离各成像透镜的光轴Y1、Y2的偏移仅为P×(L/LO)。若假定该偏移为δ,用二个成像透镜成像的被摄影物的像的距离δH成为δH=2δ+2P,即The relationship between the four imaging lenses, the imaging device and the subject related to Embodiment 1 of the present invention are shown in Fig. 3 and Fig. 4(a), (b). Fig. 3 shows the surface of an image pickup device with a pixel size of 640 pixels x 480 pixels. X 1 to X 4 are the positions of the imaging lenses, and Y 1 to Y 4 are the optical axes of the imaging lenses. FIG. 4( a ) shows a cross-sectional view taken along a horizontal plane (line AA in FIG. 3 ). If it is assumed that the distance between the optical axes of the two lenses on the same horizontal plane is 2P, the distance from the lens to the light-receiving surface is L, and the distance from the object to the lens is L O , then the object imaged by the two lenses The center of the image of the subject is shifted from the optical axis Y 1 , Y 2 of each imaging lens by simply drawing by P×(L/L O ). If it is assumed that the offset is δ, the distance δH of the image of the subject imaged by the two imaging lenses becomes δH=2δ+2P, that is

δH=2P×(1+(L/LO))           (3)δH=2P×(1+(L/L O )) (3)

仅当δH是摄象器件的间距的整数倍时,两个被摄影物的像才完全相同,人们知道,在除此以外的场合,两个区域的摄象器件能够对被摄影物的像的少许不同部分取样,并且由于通过由电装置将它们合成,即使在所述例子中也等价于在水平方向用200个像素读取被摄影物的像,因此通过焦距短的薄型摄象机能够实现和以往的摄象机同等的分辨率。Only when δH is an integer multiple of the pitch of the imaging device, the images of the two photographed objects are exactly the same. It is known that, in other cases, the imaging devices of the two regions can accurately compare the image of the photographed object. A small number of different parts are sampled, and since they are synthesized by an electric device, even in the example, it is equivalent to reading the image of the subject with 200 pixels in the horizontal direction, so it can be achieved by a thin camera with a short focal length. Achieves the same resolution as conventional video cameras.

图5是根据本发明的实施例2的摄象装置的构成图,以下各实施例表示基于图1变化的形态。在图5中,21是整体形成并内装在镜筒104中的成像透镜,在垂直和水平面上分别具备2个,共计2×2=4个。4个成像透镜21分别单独地构成4个透镜系列。此处,整体形成的4个成像透镜21作为材料由丙烯基树脂、聚碳酸脂树脂或非结晶性聚(链)烯树脂等透光树脂形成,并通过喷射成形、热硬化、光硬化或蚀刻等方法能使表面形状容易改变,由此保持透镜效果。FIG. 5 is a configuration diagram of an imaging device according to Embodiment 2 of the present invention, and the following embodiments show variations based on FIG. 1. In FIG. 5 , 21 is an imaging lens integrally formed and incorporated in the lens barrel 104 , and there are two imaging lenses on the vertical and horizontal planes, totaling 2×2=4. The four imaging lenses 21 constitute four lens series individually. Here, the four imaging lenses 21 integrally formed are formed of a light-transmitting resin such as acrylic resin, polycarbonate resin, or amorphous poly(alkene) resin as a material, and are formed by injection molding, thermosetting, photocuring, or etching. and other methods can make the surface shape easy to change, thereby maintaining the lens effect.

另外,作为被整体形成的4个成像透镜21,在丙烯基树脂、聚碳酸脂树脂或非结晶性聚(链)烯树脂等透光性树脂基片上,通过离子注入或离子交换等方法使这些材料的折射率部分地改变,也保持透镜效果,同样地能使成像功能得以实现。In addition, as the four imaging lenses 21 which are integrally formed, on a light-transmitting resin substrate such as acrylic resin, polycarbonate resin, or amorphous poly(alkene) resin, these are formed by ion implantation or ion exchange. The refractive index of the material is partially changed, and the lens effect is also maintained, which also enables the imaging function to be realized.

以下说明有关动作。由被摄影物101反射或产生的光线通过在透光性树脂上整体形成的4个成像透镜21在单独的摄象器件103的受光面上成像。此处,整体形成的4个成像透镜21的每一个分别在摄象器件103受光面上形成4个相似的被摄影物的像2,通过将它们再合成,与具有同一亮度、同一画面视角和同一分辨率的以往摄象装置比较能够实现薄型化。The related operations are described below. The light reflected or generated by the subject 101 forms an image on the light-receiving surface of the individual imaging device 103 through the four imaging lenses 21 integrally formed on the translucent resin. Here, each of the 4 imaging lenses 21 integrally formed forms 4 similar images 2 of the subject on the light-receiving surface of the imaging device 103 respectively, and by recombining them, they have the same brightness, the same picture angle and Compared with conventional imaging devices with the same resolution, it is possible to achieve thinner.

加之,在本实施例中,由于如图1的构成那样,在独立的镜筒中不必设置个成像透镜1,可以在摄象器件103的受光面前面设置一片整体形成的4个成像透镜21,因此构造变得简单,同时还达到轻量化。另外具有这样的优点,即每个成像透镜的必要的聚焦通过仅仅调整整体形成的4个成像透镜21和摄象器件103的受光面的间隔就能解决,调整时间也可以缩短。In addition, in the present embodiment, because as the composition of Fig. 1, needn't be provided with an imaging lens 1 in the independent lens barrel, can be provided with 4 imaging lenses 21 that one piece integrally forms in front of the light-receiving surface of imaging device 103, therefore The structure becomes simple and at the same time achieves light weight. In addition, it has the advantage that the necessary focus of each imaging lens can be solved by only adjusting the distance between the integrally formed four imaging lenses 21 and the light-receiving surface of the imaging device 103, and the adjustment time can also be shortened.

图6是根据本发明的实施例3的摄象装置的构成图。在图6中,31是内装在镜筒中的成像透镜,使用大致在1×10-5/℃以下的线膨胀系数的材料分别在垂直和水平面上整体形成2个从而共计4个并分别单独地构成4个透镜系统。此处,整体形成的4个成像透镜31的材料例如用玻璃等透光性无机材料形成,使用加压成形或蚀刻等方法能够使表面形状改变,因此也能保持透镜效果。Fig. 6 is a block diagram of an imaging device according to Embodiment 3 of the present invention. In FIG. 6 , 31 is an imaging lens built in the lens barrel, and two of them are integrally formed on the vertical and horizontal planes by using a material with a linear expansion coefficient of approximately 1×10 -5 /°C or less, so that there are four in total and each is individually Consists of 4 lens systems. Here, the four imaging lenses 31 integrally formed are made of, for example, a light-transmitting inorganic material such as glass, and the surface shape can be changed by methods such as press molding or etching, so that the lens effect can also be maintained.

另外,作为整体形成的4个成像透镜31在玻璃等透光性无机材料上使用离子注入或离子交换等方法部分地改变这些材料的折射率,因此,也保持透镜效果,同样能实现成像功能。In addition, the four imaging lenses 31 formed as a whole use methods such as ion implantation or ion exchange to partially change the refractive index of these materials on light-transmitting inorganic materials such as glass, so that the lens effect is also maintained, and the imaging function can also be realized.

下面说明有关动作。通过由被摄影物101反射或产生的光线整体形成的4个成像透镜31在摄象器件103的受光面上成像。整体形成的4个成像透镜31分别在摄象器件103的受光面上形成4个相似的被摄影物的像2,通过再合成,与具有同一亮度、同一画面视角以及同一分辨率的以往摄象装置比较能够实现薄型化。The related operation will be described below. An image is formed on the light receiving surface of the imaging device 103 through the four imaging lenses 31 integrally formed by light rays reflected or generated by the subject 101 . The four imaging lenses 31 integrally formed form four similar images 2 of the subject on the light-receiving surface of the imaging device 103 respectively. The device can be relatively thinned.

另外,在本实施例中,由于也不必象图1的构成那样在独立的镜筒104中设置各成像透镜1,可以在摄象器件103的受光面前面设置一片整体形成的多各成像透镜31,因此,构造变得简单,同时也能达到轻量化。另外,具有这样的优点,即每个成像透镜所必要的焦点重合仅仅通过调整整体形成的4各成像透镜31和摄象器件103的受光面的间隔就能解决,还能缩短调整时间。In addition, in the present embodiment, because also needn't arrange each imaging lens 1 in independent lens barrel 104 like the structure of Fig. , therefore, the structure becomes simple and light weight can be achieved at the same time. In addition, there is an advantage that the focal alignment necessary for each imaging lens can be solved only by adjusting the distance between the four integrally formed imaging lenses 31 and the light-receiving surface of the imaging device 103, and the adjustment time can be shortened.

此处,在考虑摄象装置的使用情况的场合,要求对于环境的变化,尤其是环境温度的变化具有稳定性。例如,希望对普通所使用的摄象装置的工作保证范围-5~45℃的50℃的变化是稳定的。涉及本发明的摄象装置如图4(b)所示在被摄影物的象的中心与各透镜的光轴的偏移δ是摄象器件的间距的整数倍以外的场合,二个区域的摄象器件可以对被摄影物的像的少许不同的部分进行取样,通过将它们合成,就会变成等价于在上述例子中在水平方向用200个像素读取被摄影物的像。影响该分辨率的因子δH由(3)式决定。根据(3)式,δH对成像透镜和摄象器件的受光面之间的距离L几乎没有影响,但对4个成像透镜的间距2P存在着比例关系,在由于环境温度的变化产生偏移的场合,即使是相隔同一距离的同一被摄影物其分辨率也会改变。Here, when the use of the imaging device is considered, stability against changes in the environment, especially changes in the environment temperature, is required. For example, it is desired to be stable against a change of 50°C in the operating guarantee range of -5 to 45°C for a commonly used imaging device. Related to the imaging device of the present invention, as shown in Figure 4 (b), when the deviation δ between the center of the image of the object and the optical axis of each lens is other than the integer multiple of the pitch of the imaging device, the distance between the two areas The imaging device can sample a few different parts of the image of the subject, and by combining them, it becomes equivalent to reading the image of the subject with 200 pixels in the horizontal direction in the above example. The factor δH that affects the resolution is determined by (3) formula. According to formula (3), δH has almost no influence on the distance L between the imaging lens and the light-receiving surface of the imaging device, but there is a proportional relationship to the distance 2P of the four imaging lenses. In some cases, the resolution of the same subject at the same distance will change.

在本实施例中,由于使用例如玻璃等透光性无机材料形成整体形成的4个成像透镜31,因此其线膨胀系数大致是1×10-5/℃以下,由于根据δH的温度的变化量被抑制在微米数量级,因此不依赖环境温度能够获得指定的分辨率的图象。In this embodiment, since the integrally formed four imaging lenses 31 are formed using light-transmitting inorganic materials such as glass, the coefficient of linear expansion thereof is approximately 1×10 -5 /°C or less. It is suppressed on the order of microns, so an image with a specified resolution can be obtained independently of the ambient temperature.

In FIG. 7 , 41 is a substrate having a linear expansion coefficient of 1×10 −5 /° C. or less. On the substrate 41, two are arranged in the vertical and horizontal directions, so that a total of 2×2=4 imaging lenses 1 a . The imaging lens 1a constitutes four lens systems individually, and is formed by using light-transmitting resins such as acrylic resin, polycarbonate resin or amorphous poly(alkene) resin, and inorganic light-transmitting materials such as glass as materials. Spray forming, thermal hardening, light hardening, pressure forming or etching can change the surface shape and maintain the lens effect.

另外,作为成像透镜1a使用丙烯基树脂、聚碳酸脂树脂或者非结晶性聚(链)烯树脂等透光性树脂或玻璃等无机透光性材料,用离子注入或离子交换等方法部分地改变这些材料的折射率,也保持透镜效果,能够实现成像功能。In addition, as the imaging lens 1a, light-transmitting resins such as acrylic resins, polycarbonate resins, or amorphous poly(alkene) resins, or inorganic light-transmitting materials such as glass are used, and the imaging lens 1a is partially changed by methods such as ion implantation or ion exchange. The refractive index of these materials also maintains the lens effect and enables the imaging function.

另一方面,基片41是用例如玻璃等透光性无机材料制作,在基片41中,使用热压接、粘结或2色成形使所述成像透镜1a接合成形。另外,也可以如图8所示在具有1×10-5/℃以下的线膨胀系数的基片上打开用来安装成像透镜1的4个小孔,并在其上安装透镜1。On the other hand, the substrate 41 is made of a light-transmitting inorganic material such as glass, and the imaging lens 1a is bonded and molded in the substrate 41 by thermocompression bonding, bonding or two-color molding. Alternatively, as shown in FIG. 8, four small holes for mounting the imaging lens 1 may be opened on a substrate having a linear expansion coefficient of 1×10 -5 /°C or less, and the lens 1 may be mounted thereon.

The light reflected or generated by the subject 101 passes through a plurality of imaging lenses 1 a on the substrate 41 to form an image on the light-receiving surface of the individual imaging device 103 . The above imaging device can be thinner than conventional imaging devices having the same brightness, the same viewing angle, and the same resolution. In addition, since only one substrate 41 on which four imaging lenses 1a are bonded or one substrate 42 on which four imaging lenses 1 are mounted can be provided, so that the structure can be simplified and lightened, and the adjustment time for focusing can also be shortened. The advantages.

另外,在本实施例中,因为使用线膨胀系数大致在1×10-5/℃以下的、例如玻璃等透光性无机材料形成接合了精度合适的4个成像透镜1a的基片41或安装了4个成像透镜1的一块基片42,根据如图4(b)所示那样的被摄影物的像的中心和各透镜的光轴的偏移δH的温度的变化量被控制在微米数量级,因此,在摄象装置的工作保证范围-5~45℃范围不依赖于50℃左右变化的环境温度,能稳定地获得指定的分辨率的图象。In addition, in this embodiment, since the substrate 41 to which the four imaging lenses 1a with appropriate precision are bonded is formed or mounted using a light-transmitting inorganic material such as glass with a linear expansion coefficient of approximately 1×10 -5 /°C or lower. A substrate 42 with four imaging lenses 1 is controlled at the micron level according to the center of the image of the subject as shown in Figure 4 (b) and the offset δH of the optical axis of each lens Therefore, in the guaranteed working range of the imaging device -5 to 45°C, images with a specified resolution can be stably obtained regardless of the ambient temperature varying around 50°C.

In Fig. 9, 51 is to change the surface shape by spray molding, thermosetting, photocuring, or etching of a light-transmitting resin such as acrylic resin, polycarbonate resin, or amorphous poly(alkene) resin. 41 has a thin plate in which two imaging lenses 52 in total are integrally formed in the vertical and horizontal directions.

The thin plate 51 having these plural imaging lenses 52 and the substrate 41 having a coefficient of linear expansion of 1×10 −5 /° C. or less are bonded, and housed in the lens barrel 104 .

另外,如图10那样,使用丙烯基树脂、聚碳酸脂树脂或非结晶性聚(链)烯树脂等透光性树脂或玻璃等无机透光性树脂,通过这些材料使用离子注入和离子交换等方法使在垂直和水平方向分别具有2个从而共计4个成像透镜52a的薄板51a部分地改变折射率后保持透镜效果,并将该薄板51a接合到具有比该薄板51a更强的刚性并具有1×10-5/℃以下的线膨胀系数的基片41上,也能获得同样效果。In addition, as shown in FIG. 10, using a light-transmitting resin such as acrylic resin, polycarbonate resin, or amorphous poly(alkene) resin, or an inorganic light-transmitting resin such as glass, using ion implantation, ion exchange, etc. The method is to make the thin plate 51a having two imaging lenses 52a in the vertical direction and horizontal direction respectively so that a total of four imaging lenses 52a partially changes the refractive index to maintain the lens effect, and the thin plate 51a is bonded to have stronger rigidity than the thin plate 51a and has 1 The same effect can be obtained also on the substrate 41 having a linear expansion coefficient of 10 -5 /°C or less.

The light reflected or generated by the subject 101 passes through the imaging lenses 52 and 52 a on the substrate 41 to form an image on the light-receiving surface of the individual imaging device 103 . Compared with conventional imaging devices having the same luminance, the same screen angle of view, and the same resolution, the imaging device can be thinned.

在该实施例中,因为4个成像透镜52、52a分别单独地构成透镜系统,并且这些成像透镜能够整体化形成,因此具有容易正确形成成像透镜间的间距的优点。In this embodiment, since the four imaging lenses 52, 52a constitute a lens system individually, and these imaging lenses can be integrally formed, there is an advantage that it is easy to accurately form the pitch between the imaging lenses.

而且,和所述的实施例相同,与具有同一亮度、同一画面视角和同一分辨率的以往的摄象装置比较能够实现薄型化。另外,因为可以设置接合了具有4个成像透镜的薄板51、51a的一块基片41,所以具有也能达到构造简单、轻量化,并且能缩短焦点重合的调整时间的优点。Furthermore, similar to the above-described embodiments, it is possible to achieve thinner thickness than conventional imaging devices having the same luminance, the same screen angle of view, and the same resolution. In addition, since it is possible to provide one substrate 41 in which the thin plates 51, 51a having four imaging lenses are bonded, there are also advantages in that the structure can be simplified, the weight can be reduced, and the time for adjusting focus can be shortened.

另外,在本实施例5中,因为将具有整体形成的4个成像透镜52、52a的薄板51、51a接合到具有大致在1×10-5/℃以下的线膨胀系数的基片41,使该基片具有刚性,所以在摄象装置的工作保证范围-5~45℃范围,即使对变化50℃左右的环境温度,透镜间距不改变,也能稳定地获得指定的分辨率的图象。In addition, in the fifth embodiment, since the thin plates 51, 51a having the four imaging lenses 52, 52a integrally formed are bonded to the substrate 41 having a coefficient of linear expansion approximately below 1×10 -5 /°C, the The substrate is rigid, so within the guaranteed working range of the imaging device -5 to 45°C, even if the ambient temperature changes by about 50°C, the lens pitch does not change, and an image with a specified resolution can be stably obtained.

In FIG. 12, 91a is four imaging lenses (group lens) provided in the lens barrel 104, and constitutes a lens series.
