Such a sensing_body sensor specifically specifies the position at which the reflected light from the sensing object is incident on the PSD, and the > cutting property to the distance of the sensing object is judged by the principle of so-called triangulation. The PSD is a very simple party light element for outputting a signal according to the position of the center of gravity of the incident light, which has the advantage of low power consumption. However, the aforementioned conventional sensing human body sensor has the following problems. That is to say, the actual situation is that the amount of information that can be obtained by the PSD is only the location information, and the response processing method that can be taken when the interference light is incident is reduced. Therefore, for example, when a sensing human body sensor including pSD is applied to an automatic faucet or the like of a washstand, there is a possibility that the mirror surface % = the amount of specular reflection generated, the interference of the miscellaneous material, and the error is sensed. Hey. a mi, refer to Figure 28, which shows the automatic faucet of the washstand in an unintentional manner, and shows the mechanism of the error sensing caused by reflection. In the figure, the symbol deletion indicates that the sense of 'reflection indicates that the light projection ^' indicates the light projection lens and the deletion indicates the acceptance) indicates the light receiving lens. The mirror surface from the face P1 of the face 914 may have a possibility of entering the light receiving element at the same angle θ as the reflected light from the sensing object 。. In this case, the position of the center of gravity of the light incident on the light-receiving element 9〇8 is indistinguishable from the specular reflection or the reflected light of the object to be detected. [Prior Art Document] Patent Document 1: Japan Special Open 2000 - 336 715 s 201215746 [Summary of the Invention] [Invention of the Invention] In the light of the above-mentioned problems, the developer is aiming at sensing the human body sensor and the automatic faucet for sensing the error performance of Qiannan. / [A device for solving the problem] The first aspect of the present invention is a sensing human body sensor including a photographing unit including a photographing element of =:!, and the photographing portion is shifted in a predetermined direction The reflected light generated by the light emitted from the light-emitting portion is sensed to sense the image of the sensing object; and the center-of-gravity specifying device 'specifies the light receiving of each of the pixels that have received the reflected light, and specifies each of the image capturing elements The center of gravity of the reflected light in the light receiving region to which the arrangement area of the pixel belongs is set (standup; 帛! determination device i, determining whether the position of the center of gravity belongs to the portion set to the received light H) The second determination means determines the center of gravity pixel based on at least one of the result of the threshold value processing on the data of the center-of-gravity pixel and the threshold value processing on the magnitude of the received light amount of the center-of-gravity pixel The visibility of the degree of light receiving, wherein the center of gravity pixel corresponds to the position of the center of gravity in a filtering processing data obtained by applying a predetermined spatial filtering process to the amount of light received by each pixel; and the sensing output device is used in the first determining device And when the second determination device has performed an affirmative determination, the output is intended to indicate that the sensing target has been sensed. The second aspect of the present invention is an automatic faucet having a drain port at the bottom. a water faucet for internal spouting, a human body sensor of the foregoing first aspect, and a water supply control for switching the spouting/stopping spouting or adjusting the spouting amount of the faucet according to the sensing signal of the sensing human body sensor a device; the imaging range of the imaging unit provided in the sensing body sensor includes a face surface constituting the inner circumferential surface of the cymbal. Efficacy] The sensing human body sensor of the present invention includes two types of determining means: the first determining means is means for determining whether or not the center of gravity position belongs to the sensing area. The second determining means is for determining the light receiving of the center of gravity pixel The sensing body sensor outputs the sensing signal when the first determining device and the second determining device have performed positive determinations. For example, when the sensing body sensor is applied to the wash table In the case of the automatic faucet, in 201215746, the specular reflection light generated by the kneading surface of the washbasin is incident on the photographic element. In particular, in the automatic faucet of the second aspect, in the photographic range of the photographic element At least a part of the surface includes the above-described surface. Therefore, when the sensing object such as the palm or the back of the hand does not exist in the imaging range, the possibility that the specularly reflected light generated by the pupil surface is incident on the imaging element becomes high. Even if the specular reflected light is incident, if the center of gravity is located outside the sensing area, the conventional sensing body sensor using PSD can be easily judged as non-sensing. However, in the case where the specular reflected light is incident and there is interference light or electrical noise that causes noise, it is impossible to avoid false sensing. For example, when specularly reflected light is incident, if each pixel in the above-mentioned sensing generates a received light amount of noise, a region having a large amount of received light will be formed inside and outside the sensing region. As a result, the intermediate position between the two regions where the amount of received light is large outside the sensing region, that is, the intermediate position between the peak of the received light amount distribution and the peak is shifted. Conventional sensing of the human body sensor cannot determine the offset of such a weight-to-position, and if the position of the center of gravity is within the sensing area, it may cause an error. In the sensor body sensor of the present invention, in addition to determining the position of the center of gravity by the second determination means, the second determination means determines the degree of light reception of the center of gravity pixel or the peripheral pixels. Sex. According to the second determination device, it is possible to determine whether or not the weight (10) in the image Ϊ = light amount distribution is at the appropriate (four) position. According to the sensing of the human body sensor, the above-described offset of the position of the center of gravity can be discriminated, and the error sensing can be prevented in advance. As described above, the sensing human body sensor of the present invention is a sensing human body sensor excellent in characteristics for suppressing the influence of specular reflection disturbance and the like to achieve stable sensing performance. The automatic faucet of the present invention having the sensing body sensor has less operational reliability. The position of the center of gravity specified by the special designation device of the center of gravity of the present invention can also be determined by the rigorous calculation of the position of the center of gravity, or it can be ensured while ensuring that the sum of the amount of light of the surrounding pixels becomes the largest position, etc. As the position of the center of gravity, the second determining means 201215746 of the line-shaped ❹丨 钱 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 The condition of the offset of the aforementioned center of gravity in the sensing area can be appropriately treated in response to the situation. Even if the first (1) cutting device has been in the shape of a shirt, as long as the foot of the center of gravity pixel can be negatively determined by the second determining device, the sensing body sensor of the invention can be avoided. The second judging device is provided. The data of the spatial filtering process in which the total amount of received light of the pixels is taken is set to be equal to or greater than the predetermined amount, and is included in the periphery of the repeating pixels. The amount of light received by the pixel is equal to the accuracy of the determination by the second determination device. In the second determination device provided by the eleventh, each pixel in the predetermined direction is changed to the position of the light # to obtain the above-mentioned transition processing material 'and the filtering portion is set at the predetermined position. In the case of the inside of the crucible, the surface of the human body that can be used for f or the like is different from the mirror surface. The edge knife of each pixel due to the diffused reflected light has a tendency to exhibit a gentle distribution shape. In the range where the degree of change in the position of the peripheral light amount of the peak of the received light amount distribution is small, it is formed over a wide range. Recorded and /5, the face of the washbasin, the wall of the (four), etc., are mostly distributed on the silk. The light received by each of the pixels generated by the specularly reflected light is different from that of the county/two, and has a sharp sharp shape. Species: In the soil knives, even in the vicinity of the peak, the degree of change in the position of the received light is more than the distribution of the amount of received light when the interference of the tooth-like eight-noise is incident, and there is a degree of mineralization that exhibits noise; 4 tendency. Of course, in the light-receiving amount distribution, the position of the light-receiving amount is changed by the above-mentioned spatial emphasis on the degree of change in the position of the light-receiving amount of each pixel, which is formed by the specular reflection light or the interference light of the noise. The characteristics of the knife cloth are used to process the data. In the 201215746 where the specular reflection light or noise has been injected, J: In the periphery of the center of gravity pixel, there is a large data 値 image: the second vomiting aspect, as described above, the peak of the received light distribution In the filtering processing data of # 幡 入 3 , , , , , , , , 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 ... material, the degree of change in the position of the received light of each pixel, the data of other pixels in the vicinity and the data of other nearby pixels are within the predetermined range; the interference condition can be used to exclude specular reflection light with high certainty or The change of the noise is determined... or the previous conditions are as follows: ========================================== The weight and the degree of the t and the degree are both the device and the calculation - the human body money 11 (4) heavy ^ special designation system is used to dissipate the total amount of light received by the photographic element t in the sum of the aforementioned amount of light, and The position of the pixel in the case where the amount of light received by the light receiving amount of each pixel is gradually increased toward the other end in the predetermined direction is specified as the position of the above-described change position. Accuracy and reduced computational load. "Computational weight ~ The preferred embodiment of the automatic faucet of the present invention has a light-receiving element that converts the received light into an electrical signal; by two: two: a female image is input to the light-receiving element The photographic data generated by the electrical signal is stored in the storage state of the light receiving storage unit and is not stored in one of the &, ° and physical storage state; The photographing control unit controls the photographing in a manner of intermittent operation of the interaction between the movable and the storage compartments, and sets the storage state in the non-storage state during the operation period only when the photographing data is acquired during the non-operational operation period. In addition to the above, in order to control the above-described storage mode switching gi, in the automatic faucet, the photographic portion is intermittent. The σ portion is intermittently operated, so that the operation time of the photographic portion can be reduced, and the photographic faucet 2 〇l2l5746 faucet The ratio of all the action time, by which ^ ^ ^ ^ ^ ^ ^ ^ ^ can be reduced, and the physical quantity stored in each pixel is read (when the reading is done at the camera) ' $ The automatic faucet photography In the department, only before the acquisition::.: the other aspect, the storage state, in addition to the above, the unstoring material is set to receive the reading processing of the aforementioned photographic data, and the pre-removal system is used for During the operation period, the resetting state can be kept as it is during the non-operation period. Therefore, when the photo-recognition period is in progress, the photographic material of each pixel is reset. When the above-mentioned photographic data is used, the reading process is re-executed, thereby U2': it is necessary to reduce the secret power in the acquisition period. Therefore, the above-mentioned four materials are short. [Embodiment] The following embodiment will be specifically described.

According to the sensing of the human body sensor 镜, the specular reflection from the surface 15〇 as shown in Fig. 8 can be prevented in advance. Light or the error sensing caused by the interference light of the noise shown in Fig. 9. In the case of the specular reflection light in Fig. 8, since the position of the center of gravity indicated by the black dot is outside the sensing area, it can be judged as Non-sensing. As shown in Fig. 9, when the position of the center of gravity is offset in the sensing area due to the interference of the interference light and the specular reflection light, the pixel of the center of gravity pixel is less than Ds. Therefore, it can be judged as non-sensing. As described above, according to the sensing body sensor of the present embodiment, the position according to the center of gravity is The hand shadowing operation can be sensed with high precision, and whether the pixel of the pixel of the center of gravity is appropriate or not, and the sensing operation can be performed with high precision by combining the threshold value associated with the image of the center of gravity pixel In the position determination of the position of the center of gravity, the sensing accuracy can be improved. In addition, in the present embodiment, the position of the center of gravity is calculated by simple calculation, but the position of the center of gravity can be calculated mathematically, and the center of gravity can be calculated by other simple calculations. Further, in the present embodiment, the threshold value Ds of the threshold value Ds of the pixel 値D(N) with respect to the center-of-gravity pixel is not specifically exemplified, depending on the characteristics of the line sensor 261 or the surrounding brightness, etc. In addition, this embodiment is an example in which the sensing human body sensor i is applied to the wash table 15, but it can also be a kitchen faucet. Further, an automatic water supply device for a urinal with an automatic washing function is provided. The sensing body can also be applied to the sensing body sensor of the embodiment. Further, the sensing body sensor can be applied to the reactive hand shielding operation or the human body to light up. Various automatic devices such as illumination or automatic doors. In addition, in the present embodiment, the sensor unit 2 and the control unit 3 are formed in an individual manner, and the sensor unit 2 and the control unit 3 may be integrally formed. The faucet 16 is housed in the faucet 16 instead of the individual configuration. (Embodiment 2) This embodiment is an example in which the configuration of the second determining device (symbol 323B in Fig. 4) is changed in accordance with the sensing human body sensor of the first embodiment. The second determination device of the present embodiment performs a determination as to whether or not the sum of the images including the periphery of the center of gravity pixel "値" is appropriate, instead of the pixel of the center-of-grain pixel. In the embodiment, as shown in Fig. 10, the difference data D(x) is referred to (see Fig. 5). The filtering process is performed to obtain the sum of the above-mentioned pixels. The spatial filtering of the embodiment 12 201215746 is processed as 'all weighting coefficients are all utilized! A 1 χ 3 pixel size operator 266 is processed. The operator 2/6A is multiplied by a weighting coefficient corresponding to the pixel D (x) of each pixel when it is superimposed on a target of 1 χ 3 pixel size centering on the pixel 266 to be calculated, and the calculation target is calculated. The data of pixel 266 is the operator of F(x). For example, if the pixel with the pixel number of 6胄 is the operation target pixel, the data obtained by the processing is H ^°(5) + D(6) + D(7). The operator 266A of Fig. 1 is a type of operator of the low-pass filter, and functions to smooth the difference data D(x). If the data of the center-of-gravity pixel (the sum of the center-of-gravity pixels Ϊth pixel 値D(X)) in the filtered processing data F(X) is equal to or greater than the predetermined value, there is a possibility that the accuracy (4) of the evaluation is improved. For example, it is possible to make an affirmative determination even when the defective pixel having the pixel 値 of the center-of-gravity pixel is smaller than the surrounding or the first-difference pixel is equivalent to the center-of-gravity pixel. On the other hand, the other configurations and effects are the same as those in the embodiment. The military rumor can be appropriately changed for the operation of the empty (four) dishes containing 1x5 pixel size of two nearby pixels. In the case of the game = fruit will be: == line changes appropriately. It can also be distributed as a normal value. Value: Pro Γ Γ t = == For the characteristics of the critical light of the transition processing data f(x), etc.: characteristics of 1 = 1, surrounding brightness or noise interference (Embodiment 3) According to the sensing human body sensor of the first embodiment, the configuration of the second determining device (symbol 323 in the fourth drawing) is changed to determine the full drawing to the third drawing. J. With regard to the inner valley, the second determination device of the eleventh embodiment will be referred to, and the risk τ is extracted..* according to Fig. 5) whether or not the appropriate embodiment i has been determined to have the center of gravity = Whether the degree of change in the position of 値D(8) is appropriate or not is also imposed on the pixel around the center of gravity pixel = the degree of change described above. For example, with the first empty, the 遽 processing, in order to find the pixel as the operand pixel, after filtering processing 13 201215746 D (5). The operator 266A of Fig. 11 is a type of operator of the high-pass filter, and the degree of change in position can be emphasized by distributing the amount of light received by the difference data D(x) in the arrangement direction of the pixels. An example of the spatial filtering process using the operator 266A is shown in Fig. 12 and Fig. 13. Fig. 12 is an example of the case where the diffused reflected light generated by the hand shielding operation is incident. Figure 13 is an example of when the interference light of the noise is incident on the sensing area. In the drawings, the graph of the difference data D(x) which is the object of the spatial filtering processing is placed on the upper layer, and the graph of the filtered processing data F(x) after the spatial filtering processing is placed on the lower layer. As shown in Fig. 12, when the diffused reflected light generated by the hand shielding operation is incident, the light-receiving amount distribution of the differential data D(x) becomes a gentle curve shape close to the normal distribution. The pixel of the filtering processing data F(x) is close to zero in the pixel of the center of gravity (shown by the black dot) near the peak of the distribution of the amount of the illuminating light and the pixels surrounding it. On the other hand, when the disturbance light of the noise is incident, there is a case where the differential material D(x) of Fig. 13 is obtained. In the case of the noise-based interference light D (in the case of illusion, the distribution of the illuminance is not smooth (4). According to the operator 266A applied to the space transition processing of the present embodiment, emphasis can be made on this. Filtration processing data F(x) of the light amount distribution. 5 <Groundness degree The second determination device of the present embodiment is a predetermined range before addition (this embodiment (4) includes pixels of two nearby two Si H ranges. =# When the absolute 値 of F(X) does not exceed the critical value Fs, the case of Fig. 13 first, with respect to the difference data d(x), is more important than the sensing ^ and the pixel 重 of the center-of-gravity pixel is established値Ds: For the filter processing data F(x), the pixel that exceeds the critical value FS in the case of 宕明. _ The surrounding pixel contains the data 値F(x) F(8) The celestial being excluded. On the other hand, the interference light of the noise of the 12th figure is from the sensing object: the case of light 'borrowed' in the example:: calculate d and: use: ▲ fruit? and implementation Example 1 is the same. To achieve the operation of the wave filter, the effect of the embodiment of 201215746 can be obtained. In addition, in the present embodiment, the threshold value Fs relative to the critical value Fs of the filtering processing data F(x) is not specifically exemplified as in the second embodiment. (Embodiment 4) This embodiment is a specific example of the control of the sensor unit 2 of Embodiment 1. With respect to the inside f: Refer to Fig. 4, Fig. 5, Fig. 14 to Fig. 17 In the following description, first, the line sensor 261 constituting the sensor unit 2 will be described with reference to the 14th item. Next, the operation of the sensor unit 2 will be described with reference to the timing chart of Fig. 15. The line sensor 261 is constructed. As shown in Fig. 14, each of the 64 pixels 260 has an integrating circuit (light receiving storage unit) 267 and retains in addition to the photodiode (light receiving element) pm which generates a current signal in response to the received light. Each of the pixel metrics is sequentially read by the photographic data output unit 268 and converted into a series (5). The charge (physical quantity) is stored according to the current signal generated by the photodiode PD1, and the voltage corresponding to the charge is output. Circuit. Mountain m Ϊ The circuit 266 is a sample-and-hold circuit for holding the peak voltage output from the integrating circuit 267, and the voltage is supplied. The holding block 266 is electrically connected to the integrating circuit 267 via the switch SW2. The J-picture data output unit 268 is used for The retention of each pixel 26 = = t = - the pixel is sequentially read, and the output portion of the "pixel-series-series S-shirts and the output" is produced. The line sensor 261 of the example and the capacitor SV of the integration circuit 267 ^IM functions as an electronic fast mode switching unit. When the switch is received by the capacitor, the photodiode PD1 is also cancelled, and the charge of the integrating circuit 267 remains zero (initial Ί_ When SW1 is on, the electric circuit corresponding to the amount of light received by the photodiode PD1. In addition, regarding the switch SW], the line sensor 261 (4) Qiu, / xian 'off state is set to a preset value. (5) (4) The SW1 system is switched to the on state according to the control of the photography control °卩31 (Fig. 4). Figure 15 illustrates the action of the sensor single * 2 . In this timing chart, the non-action 2 should be in the period of the operation of the sensor, and the period before and after it corresponds to the period of non-operation. In the figure, "PWR" is the power control signal of the sensor unit 2, and 15201215746 corresponds to the power supply state, L. Corresponds to the power cut-off state. "Just", "s", the control signal of the two switches, Hi corresponds to the closed state, l〇 corresponds to the open signal, and the control signal of ^ 乂Ϊ ^ 251 corresponds to the light-emitting state, L〇*蔷 "Ancient ί pay,. Further, Vldeo" indicates photographic data composed of one-dimensional digital image signals of pixels 値 (corresponding to a predetermined amount of υ υ) of each pixel 260. Ff 经过 Elapsed time interval after the end of the previous action period (about the non-action period of the main H is 'removed for measuring the timing of the transition to the action period ( 二自=水装置 (symbol in Fig. 1) The operation of 1〇) is stopped. At the time point of the month I] 2, when the interval is reached, the ship switches the money and resumes the supply of the line sense. At this time, the switch SW1 (integration circuit 267) of the line sensor 261 is maintained. The preset state is turned off. Therefore, even if light acts on the photodiode, the load is stored in the capacitor ci of the integrating circuit 267, and the initial value is maintained as it is. f = the point T2, the integration circuit 267 The switch is switched to the on state, and the open_SW2 of the input side of the circuit 266 is switched to the off state. Thus, the charge outputted by the photo-polar body PD1 is stored in the capacitor c, and the integration circuit is biased. When the switch SW2 is turned off, the output voltage of the integrating circuit 267 is input to the holding circuit 266 while maintaining its peak voltage. Thereafter, when it becomes =T3, ^SW1 is switched to the off state, and the switch is torn. Two-shaped filter, and In the first exposure period of the beam diode PD1, the image data output unit 268 generates an image data from the output voltage of the image pickup circuit 266. The image data output unit 268 is taken in from the image control unit 31 ("the figure is omitted As a reference timing, photographic data of 4 pixels are read every clock-pixel-pixel. The photographic data is taken by the human body detection σρ 32, and the memory is used as the non-lighting data under ambient light (the first) $ is the time point 完成7 after the completion of the output of the photographic data output unit 268, and the 251 (Fig. 4) starts to emit light, and the light-emitting state continues until the time point 7, and the time in the light-emitting state is stopped. Τ5~Τ6, the switch of the integrating circuit 2 is torn to the state of the open state water and the switch SW2 of the input side of the holding circuit 266 is switched to the off state. Thus, as in the above case, the amount of the photodiode pDi is required. The physical quantity (peak voltage) is held in the holding circuit 266. The time point is ~ the exposure period is the same as the aforementioned first exposure period, and the difference is only in the 201215746 LED element. Then, in the same manner as the post-processing in the first exposure period, the output voltage of 266 and the image data output unit 268 generate the data of the holding circuit of each pixel, which is input by the human body detecting unit 32 and memorizes the data. And output. This photographic light time data (Fig. 5). When the output of the photographic data is completed, the transmission under the light + LED light is Lo, and the supply of power to the sensor unit 2 is stopped. The time point T8 of the man, PWR Further, the control unit 3 executes the sensing processing of the user to the low power consumption mode, and the low power consumption mode only performs the timing operation of the timing during the transition period after the water supply control or the like.仃 For measuring the transition to the next movement The sensor unit 2 of the automatic 261 of the present embodiment constructed in the above manner is intermittently operated. In the pastoral setting, the line sensor is provided with an electronic shutter function, and the line sensor 261 other than the photographic material acquisition example is not stored. Therefore, before the photographic data is acquired, the physical quantity of each pixel 26 电荷 of the charge 261 of each pixel 260 is reset. This is because the operation time required to reset the line sensor 260 is reset, and the line sense can be reduced, and the image can be reduced instead of the present embodiment, and can be shorter. The physical quantity of the difference in the stored physical quantities is directly output. In this case, the photographic data of the component 251 can be directly output. Such a configuration can be realized by, for example, having the 16th configuration hair sensor 261. • Line of the Four Attack 20 In each of the pixels 26 of the 5 round line sensor 261, the holding circuit 2 switches SW21 and SW22 are connected to the integrating circuit 267. Further, a differential operation circuit 269 is connected to the lower side of the holding circuit ^, and an output holding circuit 266c is connected to the difference calculation circuit 2. Taking the timing chart of Fig. 17, 2 should be the outline of the action of 1 § 2 61. The lunar green sense is in the example of the timing chart of Fig. 17, with the LED element 2 SW1 (^ J); the switch SW1 of the product/knife circuit 267 is switched to the on state, and the switch SW22 of the input side of the holding circuit 17 201215746 is switched. During the second exposure to the off state, the peak voltage of the integrating circuit 267 is held in the holding circuit 266B. At the time point T7 B, the switch SW3 is switched to the OFF state, and the switching state is maintained until the time point T8. While the time point T7 to T8 is reached, the output voltage (voltage 値V1) of the holding circuit 266Α is input to the capacitor C3 of the arithmetic circuit 269 via the switch SW31 and held. However, when the time point T9 is reached, the switch SW32 is switched. In the off state (the switch SW33 is kept on), the switch state time point is maintained until τ1 。. During the time period T9 to Τ10, the output voltage 値V2 of the hold circuit 266Β is controlled via the switch SW32. The capacitor C3 is input to the differential operation circuit. In this af, since the switch SW33 is kept on, the difference between the voltage 21値VI and the voltage 値V2 can be maintained in the capacitance f C3 of the differential operation circuit (4). The voltage 値 of this difference is prepared for the reflected light component of the light projected from the LED S piece 251. The electric house of this difference is turned into the holding circuit 266C at the time point - ΤΓ Τ Τ 12, and is output as photographic data via the photographic data output unit 268 (omitted in Figs. 14 and 16). In this embodiment, in order to control the length of the exposure time in the light receiving operation, the electronic shutter three-electron fast is not an essential component, and may be omitted. However, instead of the electronic shutter, the optical shutter is used to physically block the light pair. A mechanical shutter of the line sensor 261. Further, other configurations and operational effects are the same as those of the embodiment. (Embodiment 5) FIG. 4 shows an example in which the human body sensor of the first embodiment is changed to change the content of the human _ 1 H processing. This content will be described with reference to Figs. 18 to 20 . The human body sensing portion of the example has the functions of two types of processing devices as a sensing process. In the sensing process by the human body sensing unit, as shown in Fig. 18, the first line: Λ1, the simple determination of the processing device (10) υ. When it is determined by the simple determination/(S1G2:Yes)' that the second processing device has made a determination in the material determination determination (S1°4: YES), it is determined that the sensation is in the step S1G1. The simple determination or the fine determination of the step sig3 is timed (si〇2: no, si〇4: no), and the corresponding period of the operation period is shifted to the non-operation period 'waiting for the next operation period. In particular, when a negative determination has been made in the simple determination of 18 201215746 in step sl1 (S102··No), the determination is made fine, and the operation period is directly ended. In the simple determination of step S101, the details of the step S1〇3 are not performed, as in the 19th, the illuminating time data of the photographic material under the LED light [(8)(10)".

In the next step S304, the position of the center of gravity calculated as described above is determined to be the sensing area located in the light receiving area 263 (refer to the embodiment! (Fig. 6). Right, in step S304, it is determined that the position of the center of gravity is located in the sensing area, and there is a predetermined distance (see Fig. 7 of the first embodiment). When the object is sensed (S3〇4: YES), the positive determination is made (S305), and the sensing signal is output as shown in step S105 in Fig. 18. On the other hand, when it is determined that the position of the center of gravity is outside the sensing area (S3) 〇4: No), the operation period is the non-sensing period, and the next operation period is waited for (S315). ^ As described above, in the sensing human body sensor 1 of the present embodiment, the simple determination and the detailed determination are performed. The two-stage determination is used to achieve the sensing. The sensing area of the human body sensor is used 201215746 = :===== (2nd picture), as long as the simple determination is made during the action of the minute, the body is the human body. Detailed determination is performed only when the sensor 1 is mostly used, etc. This can reduce the power consumption of the H-handshake operation and effectively reduce the power consumption. - 'The number of executions of the load and the light motion is only two, m is generated. When the specular reflected light acts on the human body sensor 1, the time variation of the light receiving amount is small, so if it is a brother: the incidence of each pixel 260 is very high in the injection. = two can be light; = hold = sentence one or two ====== 兼 ίί: ί: = embodiment of the sensing The body sensor 1 is an excellent sensor 11 for sensing performance and energy saving performance. The automatic faucet 16 equipped with the sensor body sensor 1 is an excellent product with less erroneous actuation and high energy saving performance. In 1st, it is called for simple judgment processing and detailed lighting. Thereby, the line sensor can be reduced - or, in the present embodiment, when the affirmative determination is made with a simple judgment, the core judgment is Γ Γ Γ ? ? The detailed determination process of a plurality of times is performed instead. In this case, the determination criteria of the detailed determination of each time are strictly set to suppress the leakage: the surface is executed in detail for the detailed determination based on the strict determination criterion, and the detailed processing can be replaced with the sense of the other embodiments. Measurement processing. In addition, the other configurations and effects are the same as those of the embodiment. (Embodiment 6) This embodiment is an example of a method of sensing a human body sensor according to Embodiment i, excluding specularly reflected light. This content will be described with reference to FIG. 19 and FIG. 21 to FIG. The sensor body sensor of the first example is an inductor that covers the LED element in the component case (symbol 252 in FIG. 2) in which the slit hole is provided, as in the embodiment i, and the sensing of the second example 201215746 The sensor is the sensor that has removed the component box. In the sensor body sensor of the first example, since the light of the LED element 251 is concentrated by the slit hole, the amount of light reflected from the line sensor 261 by the sensing object T (Fig. 21) changes. small. On the other hand, the waveform of the light amount distribution becomes a relatively sharp shape. Both of bl and b2 in Fig. 22 are examples of the light amount distribution of the reflected light which is diffused and reflected by the white sensing target τ having a high reflectance. Further, in Fig. 21, Θ indicates that the reflection angle 'S of the light based on the sensing target ’ indicates the amount of shift of the LED element 251 from the line sensor 261, and f indicates the focal length of the light receiving lens 26A. Therefore, the waveform 'generated by the diffuse reflection becomes smaller as the distance L of Fig. 21 becomes smaller, and the amount of light becomes larger, and the peak intensity thereof becomes stronger. The change in the peak intensity at this time corresponds to the change in the distance L, i.e., the distance d corresponding to the X direction on the line sensor 261. The change is regular and varies roughly along the peak intensity curve Q. On the other hand, in the waveform a1 of the light quantity distribution of the reflected light generated by the specular reflection from the pupil surface 150 of the bowl portion 151 (Fig. 1) of the non-sensing distance, as shown in Fig. 22, and the diffuse reflection The peak intensity becomes particularly large as compared with the reflected light produced. Then, by estimating the margin based on the peak intensity curve Q as a reference, by setting the curve of the threshold value R, it is possible to surely discriminate the specularly reflected light which exhibits the peak intensity exceeding the threshold value R (Fig. 23). On the other hand, if a certain amount of light is detected in the sensing region of the line sensor 261 and the peak intensity is lower than the threshold R, the reflected light generated based on the sensing object T within the sensing distance can be sensed. Waveform b 1 (Fig. 24). In addition, the same applies to the waveform b2. Next, the light amount distribution of the line sensor 261 for sensing human body sensing based on the second example is as shown in Fig. 25. The waveform b3 in the figure is an example of the light amount distribution of the reflected light from the diffused reflection of the sensing object T. The waveform a2 is an example of the light amount distribution of the reflected light generated by specular reflection from the facet ι5 of the bowl portion 150 (Fig. 1). Here, in the figure, 値 obtained by dividing the peak value by the light intensity of each pixel as the vertical axis' is displayed by superimposing the two waveforms. As is apparent from the figure, the waveform b3 has a wide waveform ', and the waveform a2 has a sharp and sharp shape. In waveform b3 and waveform a2, there is a big difference in the sharpness of the waveform, and as long as the difference in the sharpness is focused on, the two waveforms can be recognized. In the method of recognizing the waveform by using the sharpness, as shown in Fig. 26, there is a first method which is identified by the threshold α set by the gradient of the rise of the upper portion of the waveform. Regarding the waveform a2, since the rising gradient gradient β is larger than the critical value α, it can be determined that the waveform of the reflected light of the mirror 21 201215746 is set to a critical value for the gradient of the gradient of the waveform, and the waveform of the specularly reflected light can be recognized.
利用尖度來辨識波形的第2方法如第27圖所示，着眼於急遽且 尖度尚之波形a2的寬度較小者的方法。例如，若對峰值強度之2分 之1的強度（高度）中的波形寬度W設置臨界值υ，當其寬度^^為臨 界值U以下時可辨識為鏡面反射光的波形。 X 另外，亦可併用依據反射光之光量分布的峰值強度的檢測、與依 據波形形狀（尖度）的檢測來排除鏡面反射光。另外，關於其他的構成 及作用效果，亦與實施例1相同。 ' 以上，藉由實施例詳細說明本發明的具體例，惟此等具體例僅只 是揭示專利申請範圍所含之技術的一例。無庸贅述，當然不應藉由具 體例的構成或數值等來對專利申請範圍作限定式解釋。專利申請範^ 係包含利用習知技術或該技術領域之業者的知識等來將前述具體例 多樣地變形或變更的技術。 【圖式簡單說明】 第1圖為顯示具備實施例1之自動水龍頭的洗臉台之立體剖面 圖； 第2圖為顯示實施例1之感應器單元的剖面構造之剖面圖（第1 圖中的A-Α線箭頭剖面圖）； 第3圖為顯示實施例1之線感應器的立體圖； 第4圖為顯示實施例1之感測人體感應器的系統構成的方塊圖； 第5圖為顯示實施例1之差分資料之生成順序的說明圖； 第6圖為說明實施例1之重心位置之計算方法的說明圖； 第7圖為說明實施例1之感測人體感應器之感測原理的說明圖； 第8圖為顯示成為實施例1之非感測的第1射入圖案例的說明 圖； 第9圖為顯示成為實施例1之非感測的第2射入圖案例之說明 圖； 第10圖為說明實施例2之空間過濾處理的說明圖； 第11圖為顯示應用於實施例3之空間過濾處理的運算子之說明 圖； 22 201215746 12圖為顯示成為實施例3之感測的射入圖案例之說明圖； 3圖為顯示成為實施例3之非感測的射入圖案例之說明圖； 14圖為顯示實施例4之線感應器的電性構成之方塊圖； 15圖為顯示實施例4之感應器單元的動作之時序圖； 第16圖為顯示實施例4之其他線感應器的電路構成的一部分之 方塊圖； ^ Π圖為顯示包含實施例4之其他線感應器之感應器單元的動 作之時序圖； 第18圖為顯示實施例5之感測處理的流程之流程圖； 第19圖為顯示實施例5之簡易判定處理的流程之流程圖； f 20圖為顯示實施例5之詳細判定處理的流程之流程圖； 第21圖為說明實施例6之測距的原理之說明圖； 圖 第22圖為說明實施例6之鏡面反射之檢測方法的第1說明圖； 第23圖為說明實施例6之鏡面反射之檢測方法的第2說明圖； 第24圖為說明實施例6之鏡面反射之檢測方法的第3說明圖； 第25圖為說明實施例6之鏡面反射之其他檢測方法的第1說明 第26圖為說明實施例6之鏡面反射之其他檢測方法的第2 圖； 第27圖為說明實施例6之鏡面反射之其他檢測方法的第3說明 圖；以及 第28圖為說明習知例之錯誤感測的發生機制之說明圖。 【主要元件符號說明】 1 感測人體感應器 10自動供水裝置 15 洗臉台 150妹面 151盆部 152排水口 155台 156 台面 23 201215746 16 水龍頭（自動水龍頭） 160 筒體部 161 基部 162 吐水部 165 過濾板 168 吐水口 11 電磁閥 12 供水配管 2 感應器單元 21 框體 211 間隔壁 25 發光部 25A 投光透鏡 250 LED晶片 251 LED元件 252 遮光性元件盒 253 縱向狹縫孔 254 透明樹脂 26 攝影部 26A 受光透鏡 260 像素 261 線感應器（攝影元件） 263 受光區 266 、266A、266B、266C 保持電路 267 積分電路（受光儲存部） 268 攝影資料輸出部 269 差分運算電路 3 控制單元 30 控制基板 31 攝影控制部 32 人體感測部 321 差分運算裝置 24 201215746 322 重心特別指定裝置 323A第1判定裝置 323B第2判定裝置 324 感測輸出裝置 33 供水控制部 25The second method of recognizing the waveform by the sharpness is as shown in Fig. 27, and the method of focusing on the sharpness and the sharpness of the waveform a2 is smaller.
