在本实施方式中所示的传感器的结构为静电电容式传感器,但并非仅限于此,也可以是光学式、压敏式等方式的传感器。 Structure of the sensor shown in this embodiment is a capacitive sensor, but is not limited thereto, and may be an optical sensor, other forms of pressure-sensitive.

如图4所示,静电电容式的传感器20包括保护膜111、和在规定行规定列配置了电极112a的电极群112。 As shown, the capacitive sensor 20 comprises a fourth protective film 111, a predetermined row and a predetermined column electrodes 112a arranged electrode group 112.

各电极112a具有所带电荷量根据置于保护膜111上的例如手指等的凹凸(即,根据保护膜111与手指等的表面之间的距离)而改变的特性。 Each of the electrodes 112a having a charge amount in accordance with, for example, irregularities in the protective film on the finger 111 (i.e., the distance between the surface protective film 111 with a finger or the like) carried by a characteristic change. 这样,放置了指纹等的沟槽(凹进)部分的电极112a的带电量少于放置了指纹等的山(凸起)部分的电极112a的带电量。 Thus, like a fingerprint placed grooves (recessed) portion 112a of the charging electrode is less than a fingerprint or the like placed Hill (projection) 112a of the electrode portion of the charge amount.

通过将各电极112a所带电荷的电荷量转换为相应的电压值,并将该电压值转换为数字值,由此获得指纹等的图像。 Each electrode 112a by converting the amount of electric charge corresponding to the charge voltage value and the voltage value into a digital value, thereby obtaining an image such as fingerprint.

图5为表示安装有定点设备的装置12的结构方框图。 5 is a block diagram showing an apparatus with a pointing device 12 is mounted.

参照附图,安装有定点设备的装置12包括:传感器101(对应于图1~4中的传感器20);处理由传感器101获得的图像的图像处理部103;根据图像检测用户手指的动作的手指动作检测部105;将检测出的手指动作转换为计算机的输入值的输入值转换部107;根据输入来控制显示屏幕的显示(指针的位置等)的显示控制部109;和对显示屏幕进行显示的显示部111。 Referring to the drawings, a mounting apparatus with a pointing device 12 comprises: a sensor 101 (corresponding to the sensor 1 to 4 of FIG. 20); detecting a finger image according to operation of the user's finger; the image processing unit 101 processes the image sensor 103 obtained motion detecting unit 105; an input value conversion unit finger motion detected into an input value of the computer 107; to control the display screen in accordance with an input (position of the pointer, etc.) of the display control section 109; and a display on a display screen a display unit 111.

图6为使用了外罩和传感器按压部的定点设备的传感器输出图像。 FIG 6 is a pointing device using the sensor housing and the pressing portion of the image sensor output.

图6(a)为传感器按压部11即将与指纹传感器20相接触的情况;图6(b)为传感器按压部11开始与指纹传感器20相接触的情况;图6(a)为传感器按压部11与指纹传感器20相接触的情况。 FIG 6 (a) of the sensor pressing section 11 is about 20 in contact with the fingerprint sensor; the case of FIG. 6 (b) is a sensor pressing section 11 starts with the fingerprint sensor 20 in contact; FIG. 6 (a) is a sensor pressing section 11 and a fingerprint sensor 20 in contact.

图6(a)、(b)、(c)的各图中,示出了根据传感器按压部11与指纹传感器20相接触而产生的传感器输出图像200。 FIG 6 (a), (b), (c) of the drawings, it shows the sensor output image 20020 into contact with the fingerprint sensor according to the sensor pressing section 11 is generated. 如图所示,输出图像根据接触的程度而改变。 As shown, the output image is changed according to the degree of contact.

以下,将按压外罩并通过传感器按压部按压指纹传感器而产生反应的像素称为“反应像素”(图中表示为符号201)。 Pixels or less, pressing the cover and the pressing portion pressing the fingerprint sensor through the sensor to generate a reaction referred to as "response pixels" (shown by symbol 201 in FIG.).

如图所示,由于用于检测手指动作的传感器按压部11的位置和材质是固定的,因此不会发生传感器所获得图像的浓淡和清晰度易受到湿度或气温等环境差异、以及出汗的程度和皮肤硬度等个人差异及体质的影响等现有问题。 As shown, since the sensor for detecting the finger pressing the operation unit position and the material 11 is fixed, the sensor thus obtaining an image without occurrence of gradation and sharpness susceptible to environmental humidity or temperature differences, and sweat the extent of existing problems and skin hardness and other physical effects of individual differences and so on.

当与传感器表面相接触的传感器按压部为半球形或切取自球的一部分的形状时,传感器按压部与传感器表面相接触的部分随所施加的压力的增强而增大,该部分周围的传感器像素值也随之改变。 When the shape of the sensor portion of the pressing portion in contact with the sensor surface from the ball or hemispherical cut reinforcing portion with the pressing portion and the sensor surface of the sensor contacting the applied pressure increases, the sensor pixels around the portion value has changed. 传感器以连续图像信息的方式获得该动作的信息。 Sensor obtains operation information of the image information in a continuous manner. 根据该结构,传感器表面与传感器按压部的接触面积随施加压力的改变而易发生改变。 Apparent change with changing pressure is applied according to the contact area of ​​the structure, the sensor surface and the sensor pressing section.

图7和8为相对于外罩具有4个传感器按压部的定点设备的示意图,图9为图7和8所示的相对于外罩具有4个传感器按压部的定点设备的获得图像的例子、以及根据该获得图像利用反应像素的数量来计算指针的移动值之处理的示意图。 7 and FIG. 8 is a schematic view of a pointing device having a housing 4 of a sensor with respect to the pressing portion, FIG. 9 is an example shown in FIG. 7 and 8 with the pointing device to obtain an image having the four pressing portions of the sensor to the housing, and in accordance with a schematic view of an image using the number of pixels in the reaction process to calculate a movement value of the get pointer.

图10为根据所获得图像的反应像素的数量来计算指针的移动值之处理的流程图。 FIG 10 is a flowchart of a process of calculating the movement value of the pointer according to the pixel number of images obtained by the reaction.

下面参照图7~10,就相对于外罩具有4个传感器按压部的定点设备,对根据所获得图像来计算指针的移动值的处理进行说明。 Referring to FIG. 7 to 10, it has a pointing device relative to the housing 4 of a sensor pressing section, the processing of moving the pointer value is calculated based on the obtained image will be described.

在图10的步骤S101中获得图像。 The image obtained in step S101 of FIG. 10. 如上述图6的说明所示,此处的图像随传感器按压部与指纹传感器的接触程度而改变。 As described above in FIG. 6, the image sensor where the degree of contact with the pressing portion and the fingerprint sensor is changed.

在图9右侧的图的例子中,位于预先设定的区域2的传感器按压部的反应像素数S2为“20”,位于区域4的传感器按压部的反应像素数S4为“5”,而位于区域1、3的传感器按压部的反应像素数S1、S3则为最大的“20”和最小的“5”之间的值“10”。 The number of reaction sensor pressing section in the example of FIG. 9 on the right side of FIG, 2 is located in a predetermined area of ​​the pixel S2 is "20", the pressing portion of the sensor region 4 of the number of reaction pixel S4 is "5", and the pressing portion of the sensor of the number of reaction regions 3 pixels S1, S3, compared with the maximum value "10" between the "20" and minimal "5."

在图10的步骤S102中,以此方式对各区域的反应像素数进行计数。 In step S102 of FIG. 10, the reaction in this way the number of pixels of each region are counted.

在步骤S103,计算各反应像素数,并就左右及上下方向进行差分计算。 In step S103, calculating the number of pixels in each reaction, and a difference calculation on the left and the vertical direction.

在本例的情况下,左右方向的差分为Sx=(S1+S4)-(S2+S3)=(10+5)-(20+10)=-15;上下方向的差分为Sy=(S1+S2)-(S3+S4)=(10+20)-(10+5)=15。 In this embodiment, the difference between the right and left direction is divided into Sx = (S1 + S4) - (S2 + S3) = (10 + 5) - (20 + 10) = - 15; the difference between the vertical direction into Sy = (S1 + S2) - (S3 + S4) = (10 + 20) - (10 + 5) = 15. 即,指针的移动值为X方向-15,Y方向15(步骤S104)。 That is, the pointer movement direction is X -15, Y direction 15 (step S104).

因此,如图9所示,如果在获得本图像前指针的位置为Pn=(Pnx,Pny),则指针移动至Pn+1=(Pnx-15,Pny+15)的位置上(步骤S105)。 Thus, as shown in FIG. 9, if the image is obtained before the present position of the pointer is Pn = (Pnx, Pny), the pointer is moved to the position Pn + 1 = (Pnx-15, Pny + 15) on (Step S105) .

此外,虽然以上说明了外罩内侧配置4个传感器按压部以将传感器表面分为4部分,并使各部分分别与1个传感器按压部相接触的结构,但本发明并不限于此,也可以采用设有多个(2个、3个、5个……)传感器按压部的结构。 Further, while the above described sensor housing disposed inside the pressing portion 4 to the sensor surface divided into four parts, and the parts are in contact with a pressing portion of the sensor structure, but the present invention is not limited thereto, may be employed a plurality (2, 3, 5, ......) configuration of the sensor pressing section.

图11为通过获得图像(步骤S101)而连续进行指针移动(步骤S105)时的显示画面。 11 is a display screen when the continuous movement of the pointer (step S105) by obtaining an image (step S101).

在图11的显示图像中,T1~T7表示当指针或手指移动时所经过的目标的位置,一笔画成的实线表示指针实际移动的轨迹。 In the display image of FIG. 11, T1 ~ T7 indicates when the position of the pointer or finger movement target elapsed, a solid line indicates the stroke of the pointer to the actual moving locus.

根据该结构,由于即使传递手指所施加的压力的传感器按压部的排列间隔小于操作者手指的宽度也可以按压,因此可以实现使用小于手指宽度的指纹传感器将装置小型化。 According to this structure, even if the delivery pressure of the finger due to the arrangement of the applied sensor interval is less than the width of the pressing portion of the operator's fingers may be pressed, can be implemented using the fingerprint sensor smaller than a finger width of the device can be miniaturized.

另外,虽然在以上说明中说明了在面向操作者的传感器面为正方形或长方形等矩形的情况下,将该传感器面配置为面向操作者的普通的正方形,但也可以如图12所示,在面向操作者的传感器面为正方形或长方形等矩形的情况下,将该传感器面配置为相对于操作者倾斜约45 °的菱形,并将施加于该矩形的4个顶点附近的压力分别检测为操作者手指沿操作画面的上下左右方向的移动。 Further, although described in a case where the sensor surface is facing the operator and the like rectangular square or rectangular in the above description, the sensor surface is generally square configuration for the operator, but may be 12, in sensor surface facing the operator is rectangular like the case of square or rectangular configuration of the operator sensor surface inclined about 45 ° relative to the diamond, and the pressure applied to the vicinity of the vertex of the rectangle are detected as four operations moving the finger up and down direction along the operation screen.

在此情况下,可将传感器沿移动电话等中所限定的常用于输入的上下方向以及左右方向较长地配置,并达到有效利用传感器面的效果。 In this case, the sensor along the vertical direction may be a mobile phone used as defined in the horizontal direction to the input and arranged longer, and to achieve effective utilization of the sensor surface.

另外,在安装有定点设备和个人认证功能的设备中,也可以将指纹传感器以及安装设备与外罩局部连接,以便当对安装设备的使用者进行认证时卸下该外罩,当使用定点功能时装上该外罩,或者当卸下保护传感器表面的外罩进行认证时,该外罩不完全脱落。 Further, the device is equipped with a personal authentication function and a pointing device, a fingerprint sensor may be installed and connected to the local device with the cover, in order to remove the cover when the device is installed on the user authentication, when using the pointing function fashion the housing, or shroud when removing the protective authentication sensor surface, the cover is not completely off.

在本实施方式中,如果用手指沿想使移动电话等安装有定点设备的装置之指针发生移动的方向对外罩施加压力,则传感器按压部与传感器表面相接触的面积将根据该压力而改变,且该接触面积的改变将变换为指纹传感器所获得的图像信息的改变,因此,可以通过图像处理来检测出操作者手指的移动,并变换为计算机的输入值。 In the present embodiment, if the finger along want to make a cellular phone mounted direction pointer pointing device means of the movement occurring pressure is applied to the cover, the area in contact with the sensor surface of the sensor pressing section will vary according to the pressure, varying the contact area and the converted image information to change obtained by the fingerprint sensor, therefore, that an operator can detect the movement of the finger by image processing, and converts the input value into the computer.

另外,由于用于检测手指动作的传感器按压部的位置和材质通常是固定的,因此不会发生静电电容式指纹传感器所获得图像的浓淡和清晰度易受到湿度或气温等环境差异、以及出汗的程度和皮肤硬度等个人差异及体质的影响等现有问题。 Further, since the operation for detecting the finger position sensor and pressing the material portion is usually fixed, the capacitive fingerprint sensor gradation and sharpness of the obtained image is susceptible to moisture or other environmental temperature difference does not occur, and perspiration the extent of existing problems and skin hardness and other physical effects of individual differences and so on.

由于即使传递手指所施加的压力的传感器按压部的排列间隔小于操作者手指的宽度也可以按压,结果,可以实现使用小于手指宽度的指纹传感器将装置小型化。 Since the arrangement of the finger even when the delivery pressure applied by the pressing portion of the sensor interval is less than the width of the operator's finger can be pressed, the result can be implemented using the fingerprint sensor smaller than a finger width of the device can be miniaturized.

另外,由于指纹传感器通常被外罩所覆盖,因此可以防止跌落以及撞击时的损坏。 Further, since the fingerprint sensor is usually covered by the outer cover, it can be prevented and the drop impact damaged.

另外,可以通过对外罩进行装饰或着色,从而对装置的整体进行自由设计。 Further, by the cover to be decorated or colored, so that the entire apparatus be freely designed.

当与指纹传感器表面相接触的传感器按压部为半球形或切取自球的一部分的形状时,通过施加压力使传感器按压部的更多部分与传感器表面相接触,该部分周围的传感器像素值也随之改变。 When the shape of the sensor portion of the pressing portion in contact with the fingerprint sensor from the surface of the ball or hemispherical cut, by applying pressure so that more portions of the sensor surface of the sensor in contact with the pressing portion, the sensor pixel values ​​of the surrounding portion is also change. 传感器获得该动作的信息并作为连续的图像信息。 A sensor to obtain information as to the operation of the image information continuously. 该结构的优点在于,传感器表面与传感器按压部的接触面积随手指的施加压力的改变而改变。 An advantage of this structure is that the contact area of ​​the sensor surface and the sensor pressing portion with a finger to change the pressure applied is changed.

另外,将长方形的传感器表面分为4部分,并在外罩里面配置4个上述传感器按压部使各部分分别与1决导电树脂接触时,可以利用根据导电树脂与指纹传感器表面的接触面积的改变来检测的必要最小限度的传感器按压部的个数,检测出通常用于向安装有定点设备的装置的输入之屏幕的上下左右的移动。 Further, the rectangular sensor surface divided into 4 parts, and the sensor 4 disposed in the housing inside the pressing portion, respectively, when the respective portions of the conductive resin contacts a decision may be utilized according to the change in the contact area of ​​the resin and the conductive surface of the fingerprint sensor the number of the pressing portion of the sensor for detecting the minimum necessary, the detected vertical and horizontal movement of the input device generally is mounted a screen pointing device.

在面向操作者的传感器面为正方形或长方形等矩形的情况下,将该传感器面配置为相对于操作者倾斜约45°的菱形,使施加于该矩形的4个顶点附近的压力分别检测为操作者手指沿操作画面的上下左右方向的移动。 In the sensor surface facing the operator is rectangular like the case where square or rectangular, and the sensor surface arranged inclined with respect to the operator about 45 ° diamond, so that pressure in the vicinity of the four vertices of the rectangle are respectively applied to the detection of the operation moving the finger up and down direction along the operation screen. 在此情况下,可将传感器沿移动电话等中所限定的常用于输入的上下方向以及左右方向较长地配置,并达到有效利用传感器面的效果。 In this case, the sensor along the vertical direction may be a mobile phone used as defined in the horizontal direction to the input and arranged longer, and to achieve effective utilization of the sensor surface.

根据当对安装设备的使用者进行认证时卸下该外罩,而当使用定点功能时安装上该外罩的结构,即使在根据外罩的装卸来切换个人认证和定点功能时,外罩也始终与本体相连接,具有防止外罩丢失的效果。 According to remove the cover when the device is installed on the user authentication, when the housing is mounted on the structure using a pointing function, even when the personal authentication is switched in accordance with a pointing function and a detachable cover, the cover with the body always connected with the housing to prevent the loss of effect.

另外,在传感器的图像信息读取方式为静电电容式的情况下,传感器按压部的材料优选导电树脂。 Further, in a case where the image information reading method is a capacitance type sensor, and a conductive resin material is preferably pressed against the sensor portion.
