Abstract

A ranging system comprises optically-distinguishable portions (54, 56) located on a first layer (52). Another layer (58) is provided distant from the layer (52) again having optically-distinguishable portions (60,62). One of the optically-distinguishable portions (62) on layer (58) is at least substantially transparent. When an observer's eye (50) is at the correct range the portions (56) of the first layer (52) are fully visible via the transparent portions (62) of layer (58). If the user is too close (b) or too far away (c) then the user will not see the portions (56) in their entirety. The user thus knows when he or she is at the correct range. The invention may also be used to provide correct alignment between a user and an apparatus. The invention has particular, but not exclusive, application to ranging for apparatus which takes a picture of a user.

This camera may only be used for collimation in front of light components. For personal use, still life photography is special (but not limited to) The new century of the letter is about to be equipped. It can be connected with the first words or wired devices. Capacitors can increase the size of these photographic devices. However, the user of the camera can adjust the degree of possibility with the person on the other side of the user's face or the camera or camera is coming to the person. The use of electrical devices for the user's second best use of this kind of photography is special Haoyue has correctly received the new century day-to-day provider that enables the user's jacket or ranging light video camera to collimate the eyes. The camera, resolution, and spatial alignment generated by the camera are also used by the user ’s face and wall. However, the construction processor cannot represent the screen of the camera according to the problem. Therefore, due to the time judgement, the camera is clear and the camera is clear. One of the suggested solutions is to provide a pi day-in-picture " device, part of which provides users with a day-to-day method of their own face which has various disadvantages. First of all, this is a kind of high cost LCD screen is small and expensive, and it needs to. Second, if the user's face cannot be displayed, in which direction the device should be turned. Third, the available processing is only a few frames. Users may see their images and things are going in the wrong direction. An object is to provide a device that improves the above problems.

Description of the invention (2) Device for distance measurement or adjustment of collimation. The device includes a first layer and a second layer. The first layer includes at least a first region and a second region, and the first region and the second region are optically distinguishable. The second layer is separated from the first layer and includes a third region and a fourth region. The third region and the fourth region are optically distinguishable, and the fourth region is at least partially transparent. Wherein, when the distance or collimation of the device is substantially correct, the light intensity detected by the photosensitive member through the fourth region can detect at least a part of the second region. Such a collimation adjusting device provides a simple structure so that a photosensitive member can determine the relative angular direction and / or distance of the device (on a straight line or a plane) at any time. In the following examples, the photosensitive member is a human eye, but the present invention can be applied to an electronic photosensitive member. The shape of these optical discrimination areas can have various designs. The currently preferred shape is a triangle, but other shapes can also be used. For example, rectangles may be best suited for mobile communication devices because rectangles can be arranged around a liquid crystal display. In addition to triangles or other shapes, small areas with higher precision can be set in the design. Examples of such small areas are small circles or dots. When the alignment is poor, it is not possible to clearly understand the direction in which the alignment adjustment device and the photosensitive member should be rearranged from these tiny optical discrimination areas. However, such devices are also provided with some linear members, for example, in the area of a triangle, these linear members provide coarse adjustment. Once the coarse adjustment is desired, perform some further adjustments to properly align the tiny optical discrimination areas. By adjusting the relative distance between the first and second layers and the size and shape of these optical discrimination areas, the device according to the present invention can provide almost any place at any time.

Description of the invention (6) A small round part or small dot 16, 18, 20 is provided at the top corner to provide super precision, which will be explained below. The arrangement of the optical discrimination areas shown in Figures 1 (a) and (b) is to provide optical discrimination areas in the first and second layers of a device. The first and second layers are spaced from each other. Hereinafter, it will be described in more detail with reference to FIG. 2 (a). Fig. 2 (a) is a side view showing a structure manner according to an embodiment of the present invention. The side view of this device corresponds to the section lines I I-I I shown in Fig. 1 (a). The first layer 30 includes a dark region 32 and a reflective region 34. The second layer 40 includes a dark area 42 and a transparent area 44. The second layer is at a defined distance d from the first layer. The user's eye 50 shown in the figure is located above the device. The light entering the eyes is indicated by a dotted line. In Fig. 2 (a), the alignment between the eye 50 of the user and the device (on the plane shown) is completely correct. The reflective area 34 of the first layer is located directly below the transparent area 44 of the second layer. Therefore, the user's eye 50 can see the reflection image of the reflection area 34 through the transparent area 44, but cannot see any part of the dark area 32 of the first layer 30. However, Figure 2 (b) shows a different situation. In this case, the position of the device is different from that shown in Fig. 2 (a). Therefore, from the viewing angle of the eyes of the user, the appearance of the reflection area 34 has changed. It can be seen from the sight line shown in FIG. 2 (b) that the reflected light of the reflection area 34 seen by the user at this time is less. With Feng you can also see a part of the 30 dark area on the first floor. The user clearly knows that the orientation between his eyes and the device is incorrect. Because the user can see the dark area 3 2 to the right of the reflection area 34 (as shown in the figure). The device obviously needs to be rotated in direction r to obtain proper collimation.

第10頁 472136 五、發明說明（7) 由於反射區3 4與透明區4 4的相對尺寸與間距，因此可可以相對使用者眼部調整器件的方位，使反射區3 4完全看不見。在圖2 ( c )所示情況中，使用者僅看見第一層黑暗區 3 2的一部份。然而，在此情況中，器件顯然需要沿方向r 旋轉，因為使用者的視力只能感知器件的斜面。圖2已顯示如何操作本發明裝置以於一方向上產生正確方位或準直度。在與第一方向正交且與視線也正交的另一方向上，重覆此程序。圖3顯示另一允許本發明提供測距之實施例。在此圖中顯示之測距裝置5 1 ，包括一具有第一區5 4與第二區56之第一層52 ，及一具有第三區60與第四區62之第二層5 8。圖中顯示之人類眼部5 0係安排在離開裝置的正確距離或範圍上。此一正確距離可從一攝影機的焦距或所要的視野（當攝影機沒有聚焦極限時）來判定。此種配置亦可用來提供最低距離警告，以下會參照圖7說明。請看圖3 ( a )，其原理類似參照圖2說明的原理。亦即，可經由第二層58的透明區62看到第一層52的第二區 5 6。此二層相距一距離d，與先前相同。此圖中，裝置之位置與感光構件（眼部5 0 )間的距離正確，可經由第二層的透明區62完全看見第一層的第二區56。圖3 ( b )顯示裝置的位置太靠近感光構件5 0。在此情況時，經由第二層的透明區62無法完全看到第一層的第二區 5 6 ，但可看見第一層第一區5 4位於第二區5 6外侧的部份。從這種情況，使用者可判定裝置太靠近其眼部。Page 10 472136 V. Description of the invention (7) Due to the relative size and distance between the reflective area 34 and the transparent area 44, the orientation of the device can be adjusted relative to the user's eyes so that the reflective area 34 is completely invisible. In the situation shown in Fig. 2 (c), the user sees only a part of the dark zone 32 of the first layer. However, in this case, the device obviously needs to rotate in the direction r because the user's vision can only perceive the bevel of the device. Figure 2 has shown how the device of the invention is operated to produce the correct orientation or collimation in one direction. Repeat this procedure in the other direction that is orthogonal to the first direction and also perpendicular to the line of sight. Figure 3 shows another embodiment that allows the present invention to provide ranging. The ranging device 5 1 shown in this figure includes a first layer 52 having a first region 54 and a second region 56 and a second layer 58 having a third region 60 and a fourth region 62. The human eye 50 shown in the figure is arranged at the correct distance or range from the device. This correct distance can be determined from the focal length of a camera or the desired field of view (when the camera has no focus limit). This configuration can also be used to provide a minimum distance warning, which will be described below with reference to FIG. 7. Please refer to FIG. 3 (a). The principle is similar to that described with reference to FIG. That is, the second region 56 of the first layer 52 can be seen through the transparent region 62 of the second layer 58. The two layers are separated by a distance d, the same as before. In this figure, the distance between the position of the device and the photosensitive member (eye 50) is correct, and the second region 56 of the first layer can be fully seen through the transparent region 62 of the second layer. Fig. 3 (b) The display device is located too close to the photosensitive member 50. In this case, the second region 5 6 of the first layer cannot be completely seen through the transparent region 62 of the second layer, but the portion of the first region 54 that is outside the second region 56 can be seen. From this situation, the user can determine that the device is too close to his eyes.

472136 五、發明說明（8) 相反地，圖3 ( c )顯示的情況是，感光構件5 0的位置離準直裝置太遠。在此情況時，也可經由第二層的透明區62 完全看見第一層的第二區5 6。然而，在此情況中，可經由透明區6 2看見的部份第一區5 4 ，係在第二區5 6的内侧。因此，使用者（或機器，依適當情況而定）可判定測距裝置與感光構件距離太遠。本發明實施例亦可設計為只提供測距控制而無方位控制。此種配置可包括複數個光學辨別區（例如圖1 ( b )所示之三角形配置），安排在一球面上（或其部份表面上）。可正確看見三角形之一時，則指示測距正磘。在一較佳實施例中，本發明之裝置係安排為針對一感光構件兼具測距與準直調整（定方位）功能。圖1 ( b)所示之區位安排尤其適於此一目的。本發明可應用於人類肉眼視力無法辨別的較大距離。例如，使用雷射時，本發明可應用於遼擴距離之測距與方位控制（視雷射功率而定）。其中一種可能的應用是作為太空船在近地球軌道導航時的後備系統。本發明亦可應用於較短距離，例如用於機械或對接運輸工具之準直度調整。此種配置可作為後備器件，來安排對接太空艙的精密進場路徑。在此情況時，可使用多數此 ’·器件。設計用於近距離操作的器件，只在極近處時才能檢測出（被看到）。如此可提供較佳的近距離解析度，並可提供兩車太靠近的警告。圖4顯示一行動通信設備的平面圖，此通信設備配備472136 V. Description of the invention (8) Conversely, the situation shown in FIG. 3 (c) is that the position of the photosensitive member 50 is too far from the collimating device. In this case, the second region 56 of the first layer can also be fully seen through the transparent region 62 of the second layer. However, in this case, a portion of the first region 5 4 that can be seen through the transparent region 62 is tied inside the second region 56. Therefore, the user (or machine, as appropriate) can determine that the distance measuring device is too far away from the photosensitive member. The embodiment of the present invention can also be designed to provide only ranging control without azimuth control. This configuration may include a plurality of optical discrimination areas (such as the triangular configuration shown in Figure 1 (b)) arranged on a spherical surface (or a part of the surface). When one of the triangles can be seen correctly, the ranging is indicated. In a preferred embodiment, the device of the present invention is arranged to have both the function of ranging and collimation adjustment (orientation) for a light sensing member. The location arrangement shown in Figure 1 (b) is particularly suitable for this purpose. The invention can be applied to a large distance that cannot be discerned by human eyes. For example, when laser is used, the present invention can be applied to distance measurement and position control (depending on laser power). One possible application is as a back-up system for spacecraft in near-Earth orbit. The present invention can also be applied to shorter distances, such as for collimation adjustment of machinery or docking transport tools. This configuration can be used as a backup device to arrange the precise approach path to the capsule. In this case, many of these devices can be used. Devices designed for close range operation can only be detected (seen) at very close distances. This provides better close-range resolution and a warning that the two cars are too close.

However, The distance between the user and the camera is important to ensure that the user's face is approximately filled with the image frame being imaged. For this purpose, when the second area of the first layer is located at a slightly larger distance, the The triangle pattern repeats. By referring to FIG. 3 (especially FIG. 3 (a)), we can understand that this larger distance can be adjusted to provide an ideal image frame size that can display the general size of the user's face. It is not limited to use in portable equipment. When using static telephone equipment and computer equipment (such as video conference systems), the problems of correct collimation and correct image frame size will also occur. Figure 5 shows that the camera 80 is arranged on the screen of the personal computer. On the individual devices at the top, the operating principle is the same as that shown in Figure 4, that is, in order to ensure that people at the other end of the communication link can clearly view the user screen in front of the camera. The camera unit can be arranged to be left and right Adjust up or down, or the user may need to move in front of the camera unit to ensure a high-quality picture. The various types described so far can be replaced with f holograms in another embodiment. Fi picture> Poor lighting conditions It can work better because the hologram and the essence are sufficient to diffuse the light. Now the explanation of the lack of external light will be explained.

第13頁 472136 五、發明說明（ίο) 到目前為止的說明均係假設有充足的外來光可操作本發明，換言之，係假設可經由第二層的透明區清楚看見第一層的第二區。然而，實際上並非經常如此。此問題的解決法之一是，反轉第二層的透明區與其他區*以使苐二層兩區中車父大的·一區為透明區。因此，在此情況時，看見第一層第二區的任何部份時，都是不理想的。使用者須調整相對方位以最小化或消除任何第二區的出現。另一解決法是提供逆光。圖6顯示兩種可能的安排方式。其中，在裝置一側位於第一及第二層間，安排一個小 .最好高亮度的發光二極體（L E D ) 9 0。顯然地，可以使用其它替代光源，諸如白熱燈或電熒光燈。或者，可取代一侧而在第一層下方設一逆光100。在第一層下方設逆光時，務必適當選擇第一層第一及第二區的透光度。若本發明之裝置係安排在例如行動電傳通信器之液晶顯示器周圍時，可安排本裝置與顯示器共用逆光。於再一實施例中，本發明之裝置係設在一液晶顯示器 (L C D)之頂端。此時，本發明裝置之第一及第二層須設置例如一大致黑暗的區域，圍繞一小塊可見部，其位置與 LCD之可見部份一致。於是，唯當本發明裝置方位正確咋，使用者才能看見LCD。與先前相同，藉由調整第一及第二層上透明部份的相對大小及此二層間的適當間距，可決定距離設定值。在塑膠顯示螢幕之頂端與底端上網印三角形時，可達到此目的--在此情況時，每一三角形周圍有Page 13 472136 V. Description of the invention (the description so far assumes that there is sufficient external light to operate the present invention, in other words, assumes that the second area of the first layer can be clearly seen through the transparent area of the second layer . However, this is not always the case. One of the solutions to this problem is to invert the transparent area on the second floor and other areas * so that the first area in the second floor and the second area on the second floor is transparent. Therefore, in this case, it is not ideal to see any part of the first zone and the second zone. The user must adjust the relative orientation to minimize or eliminate the appearance of any second zone. Another solution is to provide backlighting. Figure 6 shows two possible arrangements. Among them, a small, preferably high-brightness light emitting diode (L E D) 90 is arranged between the first and second layers on one side of the device. Obviously, other alternative light sources may be used, such as incandescent or electric fluorescent lamps. Alternatively, instead of one side, a backlight 100 may be provided below the first layer. When setting the backlight under the first layer, it is necessary to appropriately select the light transmittance of the first and second regions of the first layer. If the device of the present invention is arranged around a liquid crystal display such as a mobile telecom communicator, the device and the display may be arranged to share backlighting. In yet another embodiment, the device of the present invention is disposed on the top of a liquid crystal display (LCD). At this time, the first and second layers of the device of the present invention must be provided with, for example, a generally dark area surrounding a small visible portion, the position of which is consistent with the visible portion of the LCD. Therefore, the user can see the LCD only when the orientation of the device of the present invention is correct. As before, the distance setting can be determined by adjusting the relative sizes of the transparent parts on the first and second layers and the proper spacing between the two layers. This is achieved by printing triangles on the top and bottom of the plastic display screen-in this case, each triangle has

第14頁 472136 五、發明說明（li) 一塊黑色，使三角形清晰可見。藉由調整螢幕位於此點之距離或厚度--使二者排成一列--(讓螢幕發光）--將與對準槍的準星類似。唯當準直度正確時，顯現三角形狀的逆光才會適當發生作用。圖7顯示本發明應用於道路安全防護裝置之實施例。圖7顯示從後方車輛所見之汽車後視圖。此圖被分成二部份。在左側所示情況中’後方來車太靠近，而根據本發明之三角形狀1 1 0為紅色。相反地，圖中右側部份顯示與本車與他車保持充分的距離。在此情況中，三角形裝置1 1 0 為綠色。請參照圖3 ( a )及（b )可了解其操作原理。圖3中所示裝置的第一區54是紅色，而第二區56是綠色。現在圖 3 ( a)所對應的後方來車距離，以國家速限而言為安全距離。然而，在較近距離時，（後方來車沒有足夠的停止空間），將可看見第一層的第一區54(請看圖3(b))。在此實施例中，第二區5 6與透明區6 2的大小必須相當大，才能確保後方來車的駕駛看得見紅色或綠色。駕駛與三角形裝置 1 1 0之間的準直度固然重要，但在實際使用中並不造成任何困難。其原因在於，在汽車道路速度中，矮高度跑車之駕駛與大型卡車駕駛之視線間的角位差相當小。在此一實施例中，可調整第一及第二層之相對間距d 連同第二區56與透明區62 (圖3 (a))之相對位置，以提供最高可能速度時的理想距離。藉由改良，可在車輛尾部設置多數三角形。每一三角形之安排可指示在某一速限範圍内（例如每小時4 0 - 5 0哩、Page 14 472136 V. Description of the invention (li) A piece of black makes the triangle clearly visible. By adjusting the distance or thickness of the screen at this point-aligning the two-(to make the screen glow)-will be similar to aiming the gun's crosshair. Only when the collimation is correct, the backlighting that appears in a triangular shape will work properly. FIG. 7 shows an embodiment of the present invention applied to a road safety protection device. Figure 7 shows a rear view of the car as seen from the rear vehicle. This figure is divided into two parts. In the case shown on the left, the car coming behind is too close, and the triangular shape 110 according to the invention is red. Conversely, the right part of the figure shows that there is a sufficient distance from the car and other cars. In this case, the triangle device 1 1 0 is green. Please refer to Figure 3 (a) and (b) for its operation principle. The first region 54 of the device shown in Fig. 3 is red and the second region 56 is green. Now the distance of the oncoming vehicle corresponding to Figure 3 (a) is the safe distance in terms of national speed limit. However, at shorter distances (there is insufficient stopping space for vehicles coming behind), the first zone 54 on the first floor will be visible (see Figure 3 (b)). In this embodiment, the size of the second area 56 and the transparent area 62 must be quite large to ensure that the driving of the car coming behind can see red or green. While the alignment between driving and the triangle device 110 is important, it does not cause any difficulties in actual use. The reason is that the angular difference between the sight of driving a low-profile sports car and driving of a large truck is relatively small at the speed of a car. In this embodiment, the relative distance d of the first and second layers and the relative position of the second region 56 and the transparent region 62 (FIG. 3 (a)) can be adjusted to provide the ideal distance at the highest possible speed. With the improvement, most triangles can be provided at the rear of the vehicle. Each triangular arrangement can indicate within a certain speed limit (such as 40-50 miles per hour,

第15頁 472136 五、發明說明（12) 5 0 - 6 0哩、6 0 - 7 0哩）的迫近後車距離。在此種安排方式中，各個單元不會因外來光而操作，但會根據車速而被逆光照亮。需要時，可以增加更多距離範圍。在更進一步之改良中，可使此種器件之綠色部份隱形，亦即使之變成黑色，以使警告三角形僅在後方來車太靠近時才會出現。圖8 ( a)顯示一系列同心圓，它們可以用作準直度圖案。此圖案的兩層，其安排如圖2及圖3所示，以於準直度及/或距離正確時，可完全看見下層的圓。當使用者視線開始偏離軸線時，會面對雲紋花樣，並直覺地知道相對本發明裝置朝哪個方向移動以重新對正。圖8 ( b )類似前圖，但其圖案為一系列等邊三角形。其操作原理是相同的。圖9顯示圖3之變體。在此例中，相同原理應用在有孔及/或開槽通往第二層2 2 0的第一層2 1 0 ，取代彼此間隔且各包括兩個光學辨別區的兩層。第二層220最好為反射性，且使用者可經由透孔/開槽2 1 2，2 1 4看見第二層。在一較佳實施例中，第二層2 2 0包括全息攝影材料。與先前相同，唯當準直度及/或距離正確時，才能看見第二層。藉由改變角度Θ可調整距離，其原理與圖3所示者相同。第一層210的厚度對應圖2及圖3中兩層的分開度。第一層 ? 1 0依適當情況可由一層壓板構成。第二層2 2 0可用逆光照亮，如前所述。本發明可為一組開孔而無任何開槽，此種設計特別適合用在一種手錶式通信器，如圖I 0所示。通信器3 0 0具有Page 15 472136 V. Description of the invention (12) 50-60 miles, 60-70 miles) The approaching vehicle distance. In this arrangement, each unit will not be operated by external light, but will be backlit by the speed of the vehicle. You can add more distance range if needed. In a further improvement, the green part of this device can be made invisible, even if it turns black, so that the warning triangle appears only when the car coming behind is too close. Figure 8 (a) shows a series of concentric circles that can be used as a collimation pattern. The two layers of this pattern are arranged as shown in Figures 2 and 3, so that when the alignment and / or distance are correct, the lower circle can be fully seen. When the user's eyes start to deviate from the axis, he will face the moire pattern and intuitively know in which direction to move relative to the device of the present invention to re-align. Figure 8 (b) is similar to the previous figure, but its pattern is a series of equilateral triangles. The operating principle is the same. FIG. 9 shows a variation of FIG. 3. In this example, the same principle is applied to the first layer 2 1 0 with holes and / or slotted access to the second layer 2 2 0, instead of two layers spaced from each other and each including two optically discriminating regions. The second layer 220 is preferably reflective and the user can see the second layer through the through holes / slots 2 1 2, 2 1 4. In a preferred embodiment, the second layer 220 comprises a holographic material. As before, the second floor can only be seen if the alignment and / or distance is correct. The distance can be adjusted by changing the angle Θ, and its principle is the same as that shown in FIG. 3. The thickness of the first layer 210 corresponds to the separation between the two layers in FIGS. 2 and 3. The first layer? 10 may be composed of a laminate, as appropriate. The second layer 2 2 0 can be illuminated with backlighting, as previously described. The present invention can be a group of openings without any slots. This design is particularly suitable for a watch-type communicator, as shown in FIG. Communicator 3 0 0 has

第16頁 472136 五、發明說明（13) 一 ·多功能榮幕3 1 0用以提供視訊呼叫、手錄功能及其他功能，諸如日記薄與通訊錄。此通信器亦設有四個孔3 2 0、 330、340、350 ，其截面類似圖9所示之裝置212、214。在圖1 0 ( a )中，該通信器在正確的準直位置，所以四個孔的底部全部可以看見。由於這些開孔為漏斗形，所以當通信器移動偏離軸線時，某些孔比其他孔先變暗（亦即，無法看見其底部）。此種情況直覺地告訴使用者應朝哪個方向傾斜以便校正。圖1 0 ( b )顯示通信器朝左傾斜，使開孔3 3 0變暗，而開孔320、340為半暗。圖1 0 ( c )顯示手錶朝後傾斜，圖1 0 ( d )則顯示手錶朝前傾斜，其結果類似。所有情況都直覺地告訴使用者應朝哪個方向傾斜器件以更正其方位。在圖1 0中，為求清晰顯示，各開孔的大小已刻意加大。實際上的開孔直徑可為0. 3mm至0. 4mm，較佳直徑為 0 . 2 5 m m以節省空間。開孔深度通常為3或4 m m ，因為直徑深度比約為1 : 1 0時，其作用良好。本發明雖已如前說明並請求其權利，但應了解其揭示内容擴及本說明書中任何明示與暗示性的教導。Page 16 472136 V. Description of the invention (13) 1. Multifunctional glory screen 3 1 0 is used to provide video call, hand record function and other functions, such as diary book and address book. This communicator is also provided with four holes 3 2 0, 330, 340, 350, and its cross section is similar to the devices 212, 214 shown in FIG. In Figure 10 (a), the communicator is in the correct collimation position, so the bottoms of all four holes can be seen. Because these openings are funnel-shaped, when the communicator moves off-axis, some holes become darker than others (that is, the bottom cannot be seen). This situation intuitively tells the user which direction should be tilted for correction. Fig. 10 (b) shows that the communicator is tilted to the left to make the openings 3 3 0 dark, while the openings 320 and 340 are semi-dark. Figure 10 (c) shows the watch tilted backwards, and Figure 10 (d) shows the watch tilted forward, with similar results. In all cases, the user is intuitively told which direction the device should be tilted to correct its orientation. In Figure 10, the size of each opening has been deliberately increased for clarity. The actual opening diameter can be 0.3 mm to 0.4 mm, and the preferred diameter is 0.25 mm to save space. The opening depth is usually 3 or 4 mm, because it works well when the diameter-depth ratio is about 1:10. Although the present invention has been described and claimed as above, it should be understood that its disclosure extends to any explicit and implicit teachings in this specification.
