Description

具轨迹检测功能的光学触控系统及方法技术领域[0001] 本发明涉及一种触控系统,,尤其涉及一种具有轨迹检测功能的光学触控系统。 The optical touch system and method having a track detection Technical Field [0001] The present invention relates to a touch system ,, in particular relates to an optical touch system having a track detection function. 背景技术[0002] 一般的触控系统主要包括一触控板、一处理装置,以及一显示面板。 [0002] Usually a touch system includes a touch pad, a processor, and a display panel. 通常使用者会将手指放在触控板上移动,以通过处理装置,来对应地移动显示面板中的一目标物(如一光标)。 Typically the user will move a finger on the touchpad and to the processing device, to correspondingly move the display panel an object (such as a cursor). 在背景技术中,通常使用者手指移动的距离会等于光标移动的距离。 In the background art, the user generally will be equal to the distance of movement of the finger movement distance of the cursor. 换句话说,触控板的大小需得和显不面板一样大,而会使得成本上升。 In other words, the size of the touch panel and the need to have as large panels without significant, but will cost is increased. 若要缩小触控板的大小,便得将光标所移动的距离,设定为手指移动的距离的一个固定的倍数,然而这样做会降低触控板的精确度。 To reduce the size of the touch panel, will have to move the cursor to the distance, a movement of the finger is set to a fixed multiple of the distance, but this would reduce the accuracy of the touch panel. 举例来说,若触控板仅宽X,则若使用者要将光标向右移动2X,他必须要将手指放在触控板上,并向右移动两次,每次最多移动X,才能使得光标向右移动2X。 For example, if only wide touchpad X, then if the user wants to move the cursor to the right 2X, he had your finger on the touchpad and move right twice, each time moving up to X, in order to 2X to the right so that the cursor moves. 或者,将触控板上所检测到手指的移动距离信息乘以两倍,如此使用者便可向右移动一次X,而可让光标向右移动2X,但这么作就降低了精确度。 Alternatively, the moving distance of the touch panel detected by doubling the finger of information, so the user can move to the right once X, and allows the cursor to the right 2X, but so as to reduce the accuracy. 因此,在背景技术的触控系统中,制造商得面临成本增加或精确度下降的难题。 Therefore, in the context of touch system technology, manufacturers have faced increased costs or decrease the accuracy of the problem. 发明内容[0003] 本发明提供一种具轨迹感测功能的光学触控系统,以解决上述问题。 [0003] The present invention provides an optical system having a touch sensing function trajectory, to solve the above problems.

[0028] 请参考图1。 [0028] Please refer to FIG 1. 图1是为说明本发明的具轨迹感测功能的光学触控系统100的示意图,在本实施例中,光学触控系统包括处理器。 1 is for explaining an optical system having a touch sensing function trajectory is a schematic view of the present invention 100, in the present embodiment, the optical touch system includes a processor. 光学触控系统包括一滤光器(filter) 210、 一感测数组220、一接近(proximity)检测器250、一移动检测器270、一光源280、一处理器130,以及一显示面板110。 The optical touch system comprises a filter (filter) 210, a sensing array 220, a close (Proximity) detector 250, a movement detector 270, a light source 280, a processor 130, and a display panel 110. 另外,于本发明的实施例中,将触控板定义为滤光器210与感测数组220的结合。 Further, in the embodiments of the present invention, the touch panel 210 is defined as a filter in combination with the sensing array 220. [0029] 滤光器210用来过滤一特定波段的光线,如可见光范围的波段。 [0029] The filter 210 serves to filter light of a specific wavelength band, such as the visible range of wavelengths. 因此,感测数组220所感测到的光线便集中于滤光器210所未滤除的波段,如不可见光的波段。 Thus, 220 sensed and focus the light sensing array 210 to filter unfiltered band, such as invisible light band. 而光源280 便根据此一特性,发射不可见光,如此,当使用者欲移动显示面板110上的光标C时,会将其手指F(即指示物)靠近到光学式触控板(其中包括滤光器210以及感测数组220)上,此时手指F便可以穿透滤光器210来抵达感测数组220。 And the light source 280 will be in accordance with this feature not emit visible light, so, when the user wants to move the cursor C on the display panel 110, which will be the finger F (i.e., the pointer) is close to the optical touch panel (including the filter on the light sensing array 210, and 220), the finger F at this time can penetrate the filter 210 to the sensing array 220 to arrive. [0030] 然后使用者可以移动他的手指F,以移动光标C。 [0030] The user may then move his finger F, to move the cursor C. 这时候光源280所发出的光线会被手指F反射至感测数组240,由于感测数组220加设了滤光器210,因此感测数组220所检测到的光线便可判断是由光源280所发射,再经过手指F反射的光线,使感测数组220得以在一预定时间内,持续取样手指F反射该特定光线的光线,以据以产生一第一感测影像信号以及一第二感测影像信号。 At this time the light emitted from the light source 280 is reflected finger F to the sensing array 240, since the sensing array 220 plus a filter 210 is provided, and therefore the sensing array 220 can be detected by light source 280 is determined by transmitting light reflected by the finger F and then through the array 220 is sensed within a predetermined time for sampling the finger F of the particular reflecting light rays, to accordingly generate a first sensing signal and a second image sensing the video signal. [0031 ] 因此,利用光源280所发出的不可见光,让手指F可在感测数组220上成像以产生感测影像信号IR,其感测影像形状可例如为指纹形状。 [0031] Thus, with the light source 280 emits invisible light, so that the finger F can be imaged to generate an image sensing signal in the IR sensing array 220, which senses a fingerprint image, for example, the shape may be a shape. 接近检测器250便可根据感测影像信号IR,判断手指F与感测数组220的距离D1,以据以产生控制信号SC2,来控制移动检测器270的启动与关闭。 The proximity detector 250 can sense a video signal IR, and the sensing finger F is determined from the array of D1 220, to generate a control signal SC2 is accordingly, to control the movement detector 270 enabling and disabling. [0032] 更明确地说,接近检测器250根据感测影像信号IR所反映出的光线强度,判断手指F与感测数组220的距离Dl。 [0032] More specifically, the proximity detector 250 based on the light sensed as reflected IR image signal, determines the distance Dl of the sensing finger F of the array 220. 当所判断的距离Dl大于一指示距离时,表示手指F可能没有在感测数组220的周围,此时可不需要作移动检测,因此控制信号SC2会关闭移动检测器270以节省电力。 When the judgment indicates a distance greater than the distance Dl, showing the finger F may not be around the sensing array 220 may not be required for motion detection at this time, so the control signal SC2 movement detector 270 turns off to save power. 反之,当所判断的距离Dl小于该指示距离时,表示手指F应该靠近于感测数组220,此时便需要作移动检测,因此控制信号SC2会启动移动检测器270以进行移动检测。 In contrast, when the determined distance Dl is less than the distance indicated, should be close to the finger F represents the sensing array 220, it needs to be moved at this time is detected, so the control signal SC2 270 starts the movement detector for detecting movement. [0033] 移动检测器270用来接收感测数组220所产生的感测影像信号IR,并根据连续数个感测影像信号IR的变化,来判断手指F的轨迹(亦即移动方向信息与移动距离信息),而产生一动态向量信号MV。 [0033] The movement detector 270 used to sense IR receiving a video signal produced by the sensing array 220, and changes according to the sequential sensing of the IR image signal to determine the trajectory of the finger F (i.e., moving direction information of the mobile distance information), generates a motion vector signal MV. 动态向量信号MV包括手指F的移动距离信息(相对距离)与移动角度。 Motion vector signal MV including a moving distance information (relative distance) and angle of movement of the finger F. [0034] 举例来说,实际上感测数组220会以一固定频率来对手指F进行取样,因此相邻的两张感测影像信号IRl与IR2(未图示)的差异即为动态向量信号MV。 Difference [0034] For example, the sensing array 220 will actually to sample the finger F at a fixed frequency, so the two adjacent signal sensing image and IRl and IR2 (not shown) is the motion vector signal MV. 也就是说,移动检测器270可将后一张感测影像信号IR2减去前一张感测影像信号IRl,便可得到手指F的动态向量信号W。 That is, the movement detector 270 may be sensed after a sensed video signal IR2 a video signal before subtracting IRl, motion vector signal can be obtained W. finger F 再者,由于知道感测数组220的取样频率,因此可以知道相邻感测影像信号IRl与IR2间隔的时间。 Furthermore, knowing the sampling frequency of the sensing array 220, it is possible to know the neighboring video signal sensing measured time interval IRl and IR2. 如此一来,根据手指F的动态向量信号MV以及相邻感测影像信号IRl与IR2间隔的时间,便可得知手指F于移动时的速度信息与加速度信息。 Thus, according to the time of the motion vector signal MV F and an adjacent finger sensing IRl and IR2 video signal interval, that can speed information of the finger F is moved in the acceleration information. [0035] 处理器130接收动态向量信号MV,并套入一预定的算法,产生控制信号SC6,以移动显示面板Iio上的光标C。 [0035] The signal processor 130 receives the motion vector MV, and set into a predetermined algorithm to generate a control signal SC6, to move a cursor on the display panel Iio C. 举例来说,处理器130可以设计为根据动态向量信号MV与手指F移动的速度信息,来移动光标C ;或者,根据动态向量信号MV与手指F移动的加速度信息,来移动光标C,加速度信息可由分析速度信息而获得。 For example, processor 130 may be designed as a motion vector signal MV according to the speed of the finger F moving information to move the cursor C; or, based on the acceleration information and the motion vector signal MV finger F is moved to move the cursor C, the acceleration information speed information obtained by the analysis. [0036] 另外,处理器130也可耦接于感测数组220 (未图标)。 [0036] Further, processor 130 may also be coupled to the sensing array 220 (not shown). 由于通过移动检测器270 得到的信息(动态向量信号MV)并无法得知手指F的实际位置,因此若为了要得知手指F的实际位置(亦即手指于触控板上的位置),处理器130便需直接接收感测影像信号IR。 Because through the information (motion vector signal MV) 270 to give a movement detector and an actual position of the finger F is not known, so in order to know if the actual position of the finger F (i.e., the touch position of the finger plate), the processing 130 will be required to directly receive the image signal sensed IR. 得知手指F的位置的好处是在于处理器130可另外再根据手指F的位置,来控制光标C移动的方式。 Advantage that the position of the finger F is in that an additional processor 130 may be in accordance with the position of the finger F, C to control the cursor movement mode. [0037] 以下图式将以实例说明本发明的光学触控系统100的运作方式。 [0037] The following figures will illustrate example operation of an optical touch system 100 of the present invention. 于下列图式中, 是以俯视的方式来表现光学触控系统100,且为了方便说明,省略滤光器210。 In the following drawings, it is a plan view of the approach to the performance of the optical touch system 100, and for convenience of explanation, the filter 210 is omitted. 另外,下列实施例仅说明感测数组220取样到相邻两感测影像信号而得出的动态向量信号MV,多个感测影像信号的运作方式可以依此类推不再赘述。 Further, the following examples merely illustrate the sensing array 220 samples the motion vector signal MV sensing two adjacent video signal obtained, a plurality of the sensing mode of operation of the video signal and so on can be omitted. [0038] 请参考图2。 [0038] Please refer to FIG 2. 图2是为说明本发明的光学触控系统100根据指示物的位移、角度与速度信息,来移动目标物的示意图。 FIG 2 is for explaining an optical touch system 100 according to the present invention, the displacement, the angle and speed information of the indicator, to move a schematic view of the target object. 如图2所示,动态向量信号MV表示手指F以角度Q2, 移动了距离D2。 2, the motion vector signal MV represents a finger F at an angle of Q2, the moving distance D2. 原本光标C会同样以角度Q2,移动距离信息D2 ;然而处理器130另外根据了手指F移动的速度信息V(D2/T,T为感测数组220的取样周期),调高了光标C所移动的距离成为D3。 Otherwise the cursor C will likewise angle Q2, D2 of a moving distance information; however, according to a further processor 130 of the finger F moving speed information V (D2 / T, T is the sampling period of the sensing array 220), the cursor C is raised moving distance becomes D3. 也就是说,距离D3与D2以及速度信息V的关系可以如下式来表示:D3 = D2XVXC = D2XD2/TXC =⑶22/T,其中C为一常数。 That is, the relationship between the distance D2 and D3 and the speed information V may be represented by the following formula: D3 = D2XVXC = D2XD2 / TXC = ⑶22 / T, where C is a constant. 举例来说,设常数C为1,若使用者在5秒(T)内以定速度信息移动了10公厘(D2),所造成光标移动的距离为20公厘(D3 = 102/5);若使用者在2秒(T)内以定速度信息移动了10公厘(D2),所造成光标移动的距离为=50 公厘(D3 = 102/2)。 For example, the constant C is set 1, when the user moves at a constant speed information 10 mm in 5 seconds (T) (D2), resulting from the movement of the cursor 20 mm (D3 = 102/5) ; within 2 seconds if a user (T) of 10 mm at a constant moving speed information (D2), the cursor movement caused by distance = 50 mm (D3 = 102/2). [0039] 请参考图3。 [0039] Please refer to FIG 3. 图3是为说明本发明的光学触控系统100根据指示物的位移、角度与加速度信息,来移动目标物的示意图。 FIG 3 is a schematic diagram for explaining the optical touch system 100 according to the present invention, the displacement, the angle and acceleration information of the indicator, to move the object. 如图3所示,动态向量信号MV表示手指F以角度Q4, 移动了距离D4。 3, the motion vector signal MV represents a finger F at an angle Q4, moved a distance D4. 原本光标C会同样以角度Q4,移动距离信息D4 ;然而处理器130另外根据了手指F移动的加速度信息E (E可为D2/ (T2),其中T为感测数组220的取样周期时间), 调高了光标C所移动的距离成为D5。 Otherwise the cursor C will likewise angle Q4, moving distance information D4; however, according to a further processor 130 of the finger F moves acceleration information E (E may D2 / (T2), where T is the sampling cycle time sensing array 220) , increase the distance moved by the cursor C becomes D5. 也就是说,距离D5与D4以及加速度信息E的关系可以如下式来表示:D5 = D4XEXC = D4XD4/T2XC = CD42/T2,其中C为一常数。 That is, the relationship between the distance D4 and D5 and the acceleration information E may be expressed as follows: D5 = D4XEXC = D4XD4 / T2XC = CD42 / T2, where C is a constant. 举例来说,设常数C为1,若使用者在5秒(T)内以从O开始加速而移动了10公厘(D4),所造成光标移动的距离4公厘(D5 = 102/52);若使用者在2秒(T)内以定速度信息移动了10公厘(D4),所造成光标移动的距离25公厘(D5 = 102/22)。 For example, the constant C is set 1, when the user within 5 seconds (T) to move from O to accelerate the start 10 mm (D4), resulting from the movement of the cursor 4 mm (D5 = 102/52 ); If the user in two seconds (T) at a given speed information of the mobile 10 mm (D4), the cursor movement caused by the distance of 25 mm (D5 = 102/22). [0040] 请参考图4。 [0040] Please refer to FIG 4. 图4是为说明当指示物的位置位于一特定区域时,本发明的光学触控系统100以别种方式来移动目标物的示意图。 FIG 4 is explained when the position pointer is located in a specific region of the optical touch system 100 of the invention in a schematic view of other ways to move the target object. 如图4所示,本发明可定义区域Al为一特定区域,以执行另一种移动目标物的方式。 4, the present invention is defined as a region Al particular region, another way to perform a moving target object. 当手指F落于区域Al内且停驻时,处理器130可设定光标C根据先前移动的方向,持续移动,而移动的速度信息可以设定为先前移动的速度信息或一预定速度信息,并不影响本发明适用。 When the finger F falls within the parking area and Al, processor 130 may set the previous cursor C moves depending on the direction, continues to move, the moving speed information may be previously set as the moving speed information or a predetermined velocity information, It does not affect the present invention is applicable. 意即可将感测数组区分为第一区域与第二区域,当指示物于第一区域内移动时,感测数组持续输出动态向量信号以移动该目标物, 当指示物移动至该感测数组的一第二区域且停驻于该第二区域时,以停驻前的该动态向量信号使该目标物持续移动。 Array is intended to be divided into a first sensing region and the second region, when the pointer moves to the first area, the sensing array continuously outputs motion vector signal to move the object when the pointer moves to the sensing when a second array region and docked to the second region to the motion vector signal before parking target the continuous movement. [0041] 图5A与图5B说明本发明的光学式触控系统中触控板与显示面板之间关系的示意图。 [0041] FIGS. 5A and 5B showing the relationship between the optical touch system of the present invention between the touch panel and the display panel will be described. 图5A表示光学式触控板与显示面板之间有重迭的区域,也就是说光学式触控板设置于显示面板的上方。 5A shows an area of ​​overlap between the optical touch panel and the display panel, an optical touch panel that is disposed above the display panel. 这种实施方式常应用于现今的智能型手机。 Often used in this embodiment of today's smart phones. 图5B表示光学式触控板与显示面板之间没有重迭的区域。 5B shows region does not overlap between the optical touch panel of the display panel. 这种实施方式常应用于笔记型计算机。 This embodiment is applied to a notebook computer normally. 本发明的光学式触控系统可以图5A或图5B来实现,亦即可应用于智能型手机、笔记型计算机,或其它电子装置。 The optical touch system of the present invention may FIG 5A or FIG 5B to implement, can also be applied to smart phone, a notebook computer, or other electronic devices. 在图5A的实现方式下,亦即所谓直接接触,处理器130所使用的函数可为线性函数。 In the implementation of FIG. 5A, i.e. so-called direct contacts, function processor 130 may be used as a linear function. 较佳地,手指F移动多少,目标物C就移动多少,或成一倍数比例关系。 Preferably, how much the finger F moves, the object C is moved much, or to a multiple proportional relationship. 在图5B的实现方式下, 亦即所谓间接接触,处理器130所使用的函数可为非线性函数。 In the implementation of FIG. 5B, i.e. a so-called indirect contact, functions used by the processor 130 may be a nonlinear function. 较佳地,光标C所移动的距离会大于手指F所移动的距离。 Preferably, the distance traveled by the cursor C will be greater than the distance of the finger F is moved. [0042] 另外,使用者可将上述图2、3、4所述的实施例于以结合或修改,例如同时考虑速度信息与加速度信息、或在特定区域内只考虑角度而不考虑速度信息与加速度信息…等, 其变化不胜枚举,应为本领域的技术人员所能轻易推导,因此不再赘述。 [0042] Further, the above-described embodiment the user may be in the 2,3,4 or modified to incorporate, for example, taking into account the velocity information and acceleration information, or only consider an angle in a particular area regardless of the speed information and acceleration information ... and the like, numerous variations thereof, should be known to those in the art can easily derive, is omitted. [0043]总结来说,本发明所提供的光学触控系统,可以根据指示物(手指)的速度信息与动态向量信号,来选择性地移动所显示的目标物(光标)。 [0043] In summary, the optical touch system of the present invention provides, according to the indicator (finger) and the speed of motion vector information signal to selectively move the object (cursor) is displayed. 如此一来,当使用者想要让光标移动较大的距离,使用者可以以较快的速度信息移动手指,光标便会移动较大的距离。 Thus, when a user wants to make the cursor move a greater distance, the user can move at a faster speed information finger, the cursor will move a greater distance. 或者,使用者可以移动手指至一特定区域,让光标持续往该方向移动。 Alternatively, the user may move the finger to a specific region, so that the cursor continues to move in that direction. 因此,本发明提供了可以降低触控板尺寸(亦即降低感测数组/滤光器的大小)同时维持精准度的方案,以让使用者更方便使用本发明的光学触控系统。 Accordingly, the present invention provides a touch panel size may be reduced (i.e., decreased sense array / filter size) while maintaining the accuracy of the program to allow users to more conveniently use the optical touch system of the present invention.
