背景技术 Background technique

[0002] 由于触控式屏幕(touch screen)能让操作者直觉地透过接触方式进行相对显示器的坐标输入的优点,触控式屏幕已成为现今显示器常见配置的输入装置。 [0002] Since the touch screen (touch screen) allows the operator to intuitively the advantage relative coordinate input contact manner through a display, a touch screen input device has become a common configuration today display. 触控式屏幕以广泛地应用于各类具有显示器的电子产品中,例如,监视器、笔记型计算机、平板计算机、自动柜员机、销售点终端机、游客导览系统、工业控制系统等。 Electronics touch screen is widely applied to various types of a display, for example, a monitor, a notebook computer, a tablet computer, ATM, point of sale terminals, tourist guide system, industrial control systems and the like.

[0003] 除了传统电阻式、电容式等操作者必须接触的触控屏幕外,利用摄像组件(image-capturing device)让操作者无需真正接触到显示器的坐标输入方式也已被采用。 [0003] In addition to the traditional resistive touch screen, capacitive operator must contact the like, using an imaging assembly (image-capturing device) allows the operator need not actually come into contact with the coordinate input display mode has been adopted. 利用摄像组件的非接触式触控屏幕(或称为光学式触控屏幕)的相关现有技术请见美国专利公告号第4,507, 557号专利,在此不多做赘述。 Using non-contact imaging assembly related prior art touch screen (or optical touch screen), see U.S. Patent Publication No. Patent No. 4,507 557 first, do no more repeated here.

[0004] 为了更准确解析输入点的位置甚至能支持多点输入,关于光学式触控屏幕的现有技术,已有多种不同光源型态、光反射组件与导光组件的设计方案被提出,以提供更多关于输入点位置的角函数,以利准确地解析输入点的位置。 [0004] In order to more accurately resolve the position of the input point even support multi-point input, the prior art optical touch on the screen, there are a variety of different patterns for light sources, light reflecting assembly and the design of the light guide assembly is presented to provide more functions on the input angular position in order to facilitate accurately resolve the position of the input point. 例如,美国专利公告号第7,460,110号专利,其揭露利用一片波导组件(waveguide)以及装设波导组件两边缘的反射镜配合光源可以造成上、下两层且同时形成的光域(coincident fields of light),藉此摄像单元可以同时撷取上、下两层不同的影像。 For example, U.S. Patent Publication No. Patent No. 7,460,110, which discloses the use of a waveguide assembly (Waveguide) and both edges of the waveguide components mounted mirrors with light source domain can cause upper and lower layers is formed and simultaneously ( coincident fields of light), whereby the imaging unit can capture simultaneously on the two images under different.

[0005] 然而,若要同时撷取上、下两层不同的影像,必须采用成本较高的矩阵式影像传感器(area image sensor)、多重直线式影像传感器(multiple-line image sensor)或两条直线式影像传感器。 [0005] However, at the same time to capture on two different images, the cost must be high matrix type image sensor (area image sensor), multiple linear image sensor (multiple-line image sensor) or two linear image sensor. 此外,采用矩阵式影像传感器、多重直线式影像传感器或两条直线式影像传感器,光学式触控屏幕需要耗费较多的运算资源才能解析这些影像传感器所撷取的影像,尤其是采用矩阵式影像传感器。 Moreover, a matrix-type image sensor, multiple linear image sensor or two linear image sensor, an optical touch screen operation takes more resources to parse the images captured image sensor, in particular a matrix-type image sensor. 此外,采用矩阵式影像传感器、多重直线式影像传感器或两条直线式影像传感器,光学式触控屏幕其系统组装所造成的误差会导致这些影像传感器感测到错的光域或感测不到光域的情况,尤其是采用两条直线式影像传感器。 Moreover, a matrix-type image sensor, multiple linear image sensor error or two linear image sensor, an optical touch screen system which leads to the assembly caused by the image sensor senses the wrong light sensing domain or less the light field, especially the use of two linear image sensor.
