In the conventional personal portable device of for example mobile phone, adopt the load module that uses keyboard usually.Conventional personal portable device comprises that a plurality of buttons of input digit and letter that are used for are so that input designated telephone number or sentence.
And traditional personal portable device can provide various functions by using Menu key and other function keys.Recently, can display graphics user interface (GUI) on the display module of personal portable device, thus can use display module with two-dimensional approach as personal computer.In this case, in order to set and carry out the function of demand, Menu key and other function keys can be used as directionkeys and use.
Though the functional shift of personal portable device must be similar to personal computer, yet, in the personal portable device of for example mobile phone, service orientation key still, they select a function or target step by step according to the finger extruding that promotes them.Although the input method inconvenience of service orientation key, yet formed custom till now by the method for using the keyboard input, and do not disclose load module so far and can diminish, still utilize the input method of keyboard basically in use by taking other input methods.For example, mobile phone can comprise requisite parts, for example printed circuit board (PCB) (PCB) and radio frequency (RF) module., the size of the requisite parts in the mobile phone and thickness considers that therefore, the miscellaneous part except that requisite parts is with regard to surplus little space only because being emphasis.
Use traditional input method of keyboard to embody a kind of single moving, import telephone number or use other menus one by one for one of them one.In addition, because single move mode makes input digit or letter become slower.Usually, the user need remember the position and the function of key for rapid input, and this bothers very much.And single move mode can't utilize the advantage of graphic user interface in the mobile phone (GUI) environment all sidedly.
Summary of the invention
Technical purpose
At present, several pointing devices of supporting gui environment are on computers disclosed.According to method of operating, spherical mouse, optical mouse, laser mouse, Trackpad are arranged in the pointing device, and board.
The pointing device that is used for computing machine in theory also can be as the pointing device of personal portable device.Yet, because the purpose of personal portable device is to carry, with body portion from extra pointing device be actually can not be as the pointing device of personal portable device.
The mouse of following the tracks of ball-type or Joystick-type can be used as pointing device, and it can be installed on the personal portable device integratedly.Yet the structure of tracking ball or operating rod needs sizable solid space to be used for installing physically, thereby has stoped the miniaturization of personal portable device.
Consider this problem, in described pointing device, the click principle that optical mouse adopted can be applied on the personal portable device.
Fig. 1 to 3 is the viewgraph of cross-section of the click principle of demonstration conventional optical mouse.
With reference to Fig. 1, the image input device 21 that uses in the conventional optical mouse comprises cover glass 41, lens 42, lightproof unit 44 and imageing sensor 46.And the light emitting diode (LED) 43 with high brightness is used as light source, and the light of launching from LED43 projects on the cover glass 41 via light source guide 47.
Be used for the conventional optical mouse of PC, light scans to the bottom surface from light source, and for sensing optics mouse moving, imageing sensor is positioned on the lens.Yet for conventional optical mouse structure is applied on the personal portable device, finger is that object moves on cover glass, and imageing sensor 46 can not need to move moving of the object that relatively moves with sensing on cover glass.
As shown in Figure 1, in conventional optical mouse structure, cover glass 41, lens 42 and imageing sensor 46 in turn are arranged vertically.Just, imageing sensor is arranged in the bottom, and the cover glass 41 that light is projected on the object is positioned at the top, and lens 42 are arranged between cover glass 41 and the imageing sensor 46.Lightproof unit 44 is inserted between lens 42 and the imageing sensor 46 to block the stray light of periphery, so that distinct image projects on the imageing sensor 46.
With reference to Fig. 2, the light that the LED43 from conventional mouse structure produces can be sent to the outside 47 of cover glass 41 by light source guide 45.
The light that transmits can be by reflecting downwards being positioned at the object localization of for example pointing on the cover glass 41, and reflected light can project on the imageing sensor 46.
With reference to Fig. 3, the light that is reflected by object passes through lens 42, lightproof unit 44 and imageing sensor 46.The finger 48 that the light that goes out from light emitted is positioned on the cover glass 41 reflects to change the path, and reflected light projects on the optical image sensor 46 via lens 42.Imageing sensor 46 can the sensing projects images variation and be electric signal with image transitions.The master controller of personal portable device can be resolved moving of object from electric signal.
Yet image input device 21 described above can not ideally make the personal portable device miniaturization.Consider the level of prior art, the minimum constructive height of the image input device in the conventional optical mouse structure is approximately 4-5mm.Yet in current personal portable device, the height that requires module is less than about 2mm.
Have difficulties because not only process super accurate structure, and the depth of focus of the image input device in the conventional optical mouse structure 21, height can't be reduced to less than 2mm.
Figure 4 and 5 are the synoptic diagram that concerns between the height of display image input equipment and the depth of focus.
With reference to Fig. 4, shown optical system with short focal length.When light 62 scans on the lens 61, on image sensor surface 63, form focus.Yet under the too short situation of focal length, light shines the surface of imageing sensor 63 with high incident angle.Therefore, if the distance between lens 61 and the imageing sensor 63 changes, it is big that the size of the focus of light 62 becomes.If it is very big that focus becomes, it is bigger than the Pixel Dimensions of imageing sensor 63 that the size of point may become.Ground for reference, the distance between lens 61 and the imageing sensor 63 tend to form when the assembling load module, because because the generation of structure allowable error can produce defective.
On the other hand, the optical system with long-focus as shown in Figure 5.When light 65 scans on the collector lens 64, also on image sensor surface 66, form focus.In this case, because the focal length long enough between collector lens 64 and the image sensor surface 66, light 65 almost is vertically to shine image sensor surface 66 with low incident angle.Therefore, when the distance between lens 65 and the image sensor surface 66 changed, the spot size of focus was less relatively, thereby had reduced or do not produce defective.To a certain degree to produce, the size of focus can be greater than the Pixel Dimensions of imageing sensor as the fruit structure allowable error.
Therefore, in traditional optical mouse structure, because cover glass, lens and imageing sensor arrange along optical axis direction, and make the height of basic equipment be restricted, the depth of focus of optical system also is restricted.
