  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of a security system 1 to which the present invention is applied. The security system 1 includes a security camera 11 and a receiver 12.

  The security camera 11 is installed outdoors (for example, a front door of a house, a garden, etc.), and the receiver 12 is installed indoors (for example, an indoor entrance, a living room, etc.). The security camera 11 includes a photo sensor 124 and a microwave sensor 125 (described later with reference to FIG. 14), and detects an event such as movement of an object. The security camera 11 and the receiver 12 can communicate wirelessly. The security camera 11 includes a built-in video camera 122 and a microphone 123 (described later with reference to FIG. 14), a photosensor 124, and Control is performed based on information detected by the microwave sensor 125, and either or both of an image signal and an audio signal are transmitted to the receiver 12.

  The receiver 12 receives an image signal, an audio signal, or detection information transmitted from the security camera 11, and a display and a speaker (both of which are provided in the receiver 12 and configured by an LCD (Liquid Crystal Display), etc. (Not shown) and display or output the image, sound, or detection information. Thereby, the user can grasp | ascertain indoor conditions indoors, such as whether an intruder exists outdoors.

  Further, the receiver 12 communicates with a device such as a television receiver (not shown), a mobile phone, a personal computer, etc., and an image, sound, or detection information is transmitted as necessary to a device such as a television receiver or a mobile phone. May be displayed or output.

  2 to 4 are diagrams illustrating the principle that the movement of the object is detected by the microwave sensor 125. The microwave sensor 125 irradiates the region 10 with the microwave, detects the microwave reflected by the object, and outputs a detection signal. The microwave sensor 125 outputs a detection signal 31 when an object approaches the microwave sensor 125, and outputs a detection signal 32 when the object moves away.

  As shown in FIG. 2, an object (not shown) moves along the arrow 21 from the left to the right in the drawing in front of the security camera 11 to which the microwave sensor 125 is attached (crosses the front of the security camera 11). In this case, the object will approach until the object reaches the front of the microwave sensor 125, and will move away thereafter. Therefore, the output of the microwave sensor 125 at this time is as shown in FIG. FIG. 3 is a diagram illustrating a waveform of a detection signal output from the microsensor 125 with the horizontal axis representing time and the vertical axis representing output.

  That is, during the period until the object reaches the front of the microwave sensor 125, the output value of the detection signal 31 indicating the approach of the object becomes high (the detection signal 31 is output). In addition, during a period after the object passes the front of the microwave sensor 125, the output value of the detection signal 32 indicating the separation of the object becomes high (the detection signal 32 is output).

  As shown in FIG. 4, an object (not shown) moves in front of the security camera 11 to which the microwave sensor 125 is attached along the arrow 22-1 from the top to the bottom in the drawing (perpendicular to the security camera 11). The microwave sensor 125 that has detected the object is a detection signal that indicates the approach of the object when the object is moving from the bottom to the top in the figure along the arrow 22-2 (that is, vertically away from the security camera 11). 31 or a detection signal 32 representing the separation of the object is output. An example of the output signal at this time is shown in FIG.

  Also in FIG. 5, as in the case of FIG. 3, the object is the microwave sensor 125 outputs the detection signal 31 and the detection signal 32. Thus, although the approach or separation of the object can be determined only by the output from the microwave sensor 125, whether the object is moving in the lateral direction as indicated by the arrow 21 (FIG. 2) or the arrows 22-1 and 22 -2 (FIG. 4), it cannot be determined whether the object is moving in the vertical direction.

  On the other hand, when the object moves in the vertical direction, it is impossible to accurately determine whether the object is approaching or moving away with only the photosensor 124. This will be described below with reference to FIGS.

  FIG. 6 shows that the object 20-1 whose luminance is lower than the background 31 is shown along the arrow 23-1 with respect to the security camera 11 to which the photosensor 124 that receives the light from the region 30 and outputs the detection signal is attached. It is a figure showing a mode that it approaches to the vertical direction and then leaves | separates to the vertical direction along the arrow 23-2. In this case, the photosensor 124 outputs a detection signal 51 as shown in FIG.

  FIG. 7 is a diagram illustrating a waveform of a detection signal output from the photosensor 124 with the horizontal axis representing time and the vertical axis representing an output value. The photosensor 124 detects light emitted from the object 20-1 in the region 30 (or light reflected by the object 20-1) and changes the output value of the detection signal. In this example, since the brightness of the object 20-1 is lower than that of the background, the output value of the detection signal 51 decreases as it approaches the photosensor 124, and then the output value of the detection signal 51 increases as it moves away from the photosensor 124.

  FIG. 8 shows that the object 20-1 whose brightness is lower than that of the background 31 is separated in the vertical direction along the arrow 24-1, and then along the arrow 24-2, with respect to the security camera 11 to which the photosensor 124 is attached. It is a figure showing a mode that it approaches in the vertical direction. In this case, the photosensor 124 outputs a detection signal 52 as shown in FIG. That is, since the brightness of the object 20-1 is lower than that of the background 31, the output value of the detection signal 52 increases as the distance from the photosensor 124 increases, and the output value of the detection signal 52 decreases as the distance from the photosensor 124 increases.

  FIG. 10 shows that the object 20-2 having higher brightness than the background 31 approaches the security camera 11 with the photosensor 124 attached in the vertical direction along the arrow 25-1, and then along the arrow 25-2. It is a figure showing a mode that it leaves | separates to the vertical direction. In this case, the photosensor 124 outputs a detection signal 53 as shown in FIG. That is, since the brightness of the object 20-2 is higher than that of the background 31, the output value of the detection signal 53 increases as it approaches the photosensor 124, and then the output value of the detection signal 53 decreases as it moves away from the photosensor 124.

  In FIG. 12, with respect to the security camera 11 to which the photosensor 124 is attached, the object 20-2 having a higher brightness than the background 31 is separated in the vertical direction along the arrow 26-1, and then along the arrow 26-2. It is a figure showing a mode that it approaches in the vertical direction. In this case, the photosensor 124 outputs a detection signal 54 as shown in FIG. That is, since the brightness of the object 20-2 is higher than that of the background 31, the output value of the detection signal 54 decreases as it moves away from the photosensor 124, and the output value of the detection signal 54 increases as it approaches the photosensor 124 thereafter.

  As shown in FIGS. 7 and 13, when an object 20-1 having a lower brightness than the background 31 approaches and then leaves (in the case of FIG. 6), and after an object 20-2 having a higher brightness than the background 31 leaves. When approaching (in the case of FIG. 12), the detection signals 51 and 54 of the photosensor 124 have the same waveform. Further, as shown in FIGS. 9 and 11, when the object 20-1 having a lower brightness than the background 31 approaches after being separated (in the case of FIG. 8), the object 20-2 having a higher brightness than the background 31 approaches. In the case of separation after this (in the case of FIG. 10), the detection signals 52 and 53 of the photosensor 124 have the same waveform. For this reason, it is not possible to accurately determine whether an object is approaching or moving away from only the detection signal from the photosensor 124.

  However, for example, if two photosensors are mounted on the left and right sides of the security camera 11 so that their detection ranges do not overlap, and the signals detected by the photosensors are analyzed, the object is moving in the horizontal direction. Can be determined. The photo sensor detects the light emitted from the object (or the light reflected from the object) and outputs a detection signal. Therefore, when the object moves from left to right, first, the detection that the left photo sensor generates is detected. The output value of the signal changes, and then the output value of the detection signal generated by the right photosensor changes. Thereby, it can be determined that the object is moving in the horizontal direction (from left to right).

  Therefore, in the present invention, the security camera 11 includes one microwave sensor 125 and two photosensors 124-1 and 124-2 (when it is not necessary to individually distinguish both, Is provided). FIG. 14 is a block diagram showing the configuration of the security camera 11.

  The security camera 11 includes a control unit 121, a video camera 122, a microphone 123, photosensors 124-1, 124-2, a microwave sensor 125, a communication unit 126, and a power supply unit 127. The battery 131 supplies necessary power to each part of the security camera 11.

  For example, the control unit 121 configured by a microcomputer or the like controls operations of the video camera 122, the microphone 123, the photosensors 124-1 and 124-2, the microwave sensor 125, the communication unit 126, and the power supply unit 127. To do. The functional configuration of the control unit 121 will be described later with reference to FIG.

  The video camera 122 shoots a situation in an outdoor shooting area (for example, a front door situation or a garden situation) based on the control of the control unit 121 as needed. As a result, if there are visitors, trespassers, others, or objects (herein referred to as objects), they are photographed. The microphone 123 collects sound within the sound collection area (for example, a voice or action sound of an illegal intruder, an object destruction sound by an illegal intruder, etc.), converts it into an electric signal, and supplies the electric signal to the control unit 121.

  The photosensors 124-1 and 124-2 receive light emitted from an object (not shown) (or light reflected by the object), convert the received light into an electric signal, and supply the electric signal to the control unit 121. The microwave sensor 125 generates a microwave, detects a reflected wave when the microwave is reflected by an object, and generates a detection signal indicating whether the reflected wave is ahead or behind the reference phase. , Supplied to the control unit 121. This phase advance and delay is due to the Doppler effect and corresponds to the approach or separation of the object.

  The communication unit 126 acquires an image signal or an audio signal supplied from the video camera 122 or the microphone 123 based on the communication control signal from the control unit 121 and transmits the image signal or the audio signal to the communication unit (not shown) of the receiver 12. The power supply unit 127 supplies power from the battery 131 to the video camera 122, the microphone 123, the photo sensor 124, the microwave sensor 125, and the communication unit 126 based on control by the control unit 121. The battery 131 may be either a primary battery or a secondary battery.

  Note that the power consumption of the video camera 122 and the microphone 123 greatly exceeds the power consumption of the microwave sensor 125 and the photosensor 124. In the video camera 122 and the microphone 123, the former consumes more power, and in the microwave sensor 125 and the photosensor 124, the former consumes more power.

  FIG. 15 is a block diagram showing a functional configuration of the security camera 11 of FIG. Note that components corresponding to the configuration of the security camera 11 in FIG. 14 are denoted by the same reference numerals, and description thereof is omitted. The control unit 121 includes a detection unit 151 and a processing unit 152.

  The detection unit 151 determines whether an event (such as movement of an object) has been detected based on the detection signal from the photosensor 124, and the event is detected based on the detection signal from the microwave sensor 125. It is determined whether or not. In addition, the detection unit 151 outputs detection information to the processing unit 152 based on a determination result as to whether or not an event has been detected by the photo sensor 124 and the microwave sensor 125. The processing unit 152 controls the power supply unit 127 based on the video camera power control signal, the microphone power control signal, and the communication power control signal based on the detection information, and sends the video camera 122, the microphone 123, and the communication unit 127 to the power supply unit 127. The power supply from the battery 131 is controlled.

  FIG. 16 shows an external configuration of the security camera 11. FIG. 16A is a view of the security camera 11 as viewed from the front (front). In this example, a video camera 122 composed of a CCD or the like is provided at the lower center of the security camera 11. A microwave sensor 125 is provided above the video camera 122. Photosensors 124-1 and 124-2 are provided on the left and right sides of the microwave sensor 125, respectively.

  FIG. 16B is a diagram illustrating a configuration of the security camera 11 as viewed from above in FIG. 16A. A region 171 indicated by hatching in the drawing represents a range in which the microwave sensor 125 can detect a reflected wave when the microwave is generated and reflected by the object, and the directivity of the microwave sensor 125 is indicated. Represents.

  Similarly, areas 172-1 and 172-2 indicated by oblique lines represent ranges in which the photosensors 124-1 and 124-2 can detect light emitted from the object (or light reflected by the object), respectively. This represents the directivity of the photosensors 124-1 and 124-2.

  With reference to FIG. 17 thru | or FIG. 20, a mode that the movement of the horizontal direction of an object is detected by the photosensors 124-1 and 124-2 is demonstrated.

  FIG. 17 is a diagram illustrating a state in which an object (not shown) in front of the security camera 11 moves in the horizontal direction from the left to the right in the drawing along the arrow 191. In this case, respective detection signals are output by the photosensors 124-1 and 124-2 attached to the security camera 11.

  When an object moving from the left in the figure first enters the region 172-2, the photosensor 124-2 detects light emitted from the object, and the output value of the detection signal from the photosensor 124-2 changes. Thereafter, when the object further moves to the right and goes out of the region 172-2, the output value of the detection signal from the photosensor 124-2 changes. When the object further moves to the right and enters the region 172-1, the photosensor 124-1 detects light emitted from the object, and the output value of the detection signal from the photosensor 124-1 changes. Thereafter, when the object further moves to the right and goes out of the region 172-1, the output value of the detection signal from the photosensor 124-1 changes.

  FIG. 18 is a diagram illustrating waveforms of the detection signal 211-1 from the photosensor 124-1 and the detection signal 211-2 from the photosensor 124-2, with the vertical axis representing the output value and the horizontal axis representing time. In this example, it is assumed that the output level of the detection signals of the photosensors 124-1 and 124-2 is set to about 100 when no object is present (when only the background 31 is present). If the luminance of the object is lower than that of the background 31 and the photosensor 124-1 or 124-2 detects the object, the output value of the detection signal 211-1 or 211-2 is decreased.

  As shown in the figure, when an object enters the area 172-2 (around time 110 on the time axis), the output level of the detection signal 211-2 decreases to about 60, and then the object moves to the area 172-2. 2 (around time 130 on the time axis), the output value of the detection signal 211-2 returns to about 100. When the object further moves to the right and enters the region 172-1 (around time 150 on the time axis), the output level of the detection signal 211-1 decreases to about 60, and then the object further moves to the right. However, when going out of the region 172-1 (around time 160 on the time axis), the output level of the detection signal 211-1 has returned to about 100.

  That is, as the object moves, the detection signal 211-2 first changes, and then the detection signal 211-1 changes. Thereby, it can be seen that the object has moved from left to right (laterally).

  FIG. 19 is a diagram showing a state in which an object not shown in front of the security camera 11 moves laterally from the right to the left in the drawing along the arrow 192, contrary to the case of FIG. In this case, the detection signals from the photosensors 124-1 and 124-2 have waveforms as shown in FIG.

  When an object enters the area 172-1 (around time 110 on the time axis), the output level of the detection signal 211-1 decreases to about 60, and then the object goes out of the area 172-1 ( Around the time 130 on the time axis), the output value of the detection signal 211-1 returns to about 100. When the object moves to the left and enters the region 172-2 (around time 150 on the time axis), the output level of the detection signal 211-2 decreases to about 60, and then the object further moves to the left. When the signal goes out of the region 172-2 (around time 170 on the time axis), the output level of the detection signal 211-2 returns to about 100.

  That is, with the movement of the object, the detection signal 211-1 first changes, and then the detection signal 211-2 changes. As a result, it can be seen that the object has moved from right to left (laterally).

  In this way, according to the detection signals output from the photosensors 124-1 and 124-2 attached to the left and right of the security camera 11, whether the object has moved laterally, that is, whether the object has moved from left to right, or from the right It can be determined whether it has moved to the left.

  Next, with reference to FIG. 21 to FIG. 24, how the movement of the object is detected by the photo sensor and the microwave sensor will be described. FIG. 21 is a diagram illustrating how an object moves from the left to the right in front of the security camera 11 as in the case of FIG. 17. The operations of the photosensors 124-1 and 124-2 are the same as in FIG. 17, but in the case of FIG. 21, when an object that has moved from the left enters the region 171, the microwave sensor 125 hits the object and reflects it. The detected microwave is detected and a detection signal is output.

  As described above, the microwave sensor 125 detects the reflected wave when the microwave is reflected by the object, determines whether the reflected wave is ahead or behind the reference phase, and detects the approach of the object. A detection signal (hereinafter referred to as an approach signal) or a detection signal (hereinafter referred to as a separation signal) indicating the separation of an object is output. In the case of FIG. 21, an object that has moved from the left in the drawing along the arrow 191-1 enters the region 171, and a microwave sensor attached to a position 195 near the center of the region 171, ie, the center of the security camera 11. Until the point closest to 125 is reached, an approach signal is output. Thereafter, a separation signal is output until the object moves to the right from the position 195 and moves out of the region 171 along the arrow 191-2.

  FIG. 22 shows the waveforms of the detection signal 211-1 from the photosensor 124-1 and the detection signal 211-2 from the photosensor 124-2, with the output value on the vertical axis and the time on the horizontal axis, as in FIG. 18. FIG. 8 is a diagram illustrating waveforms of an approach signal 221-1 and a separation signal 221-2 by the microwave sensor 125 in a superimposed manner. The approach signal 221-1 and the separation signal 221-2 have an output level of about 60 to 70 in a normal state (when the approach or separation of the object is not detected). When detected, the output level is raised to about 250.

  In FIG. 22, the waveforms of the detection signals 211-1 and 211-2 by the photosensors 124-1 and 124-2 are the same as those in FIG. 18, but when an object enters the region 171 (on the time axis) Around time 110), the output level of the approach signal 221-1 rises to about 250, and then the output level of the approach signal 221-1 when the object reaches near the center of the region 171 (near time 130 on the time axis). Has returned to about 60, and the output level of the separation signal 221-2 has increased to about 250 at approximately the same timing. When the object moves to the right and leaves the area 171 (near time 170 on the time axis), the output level of the separation signal 221-2 returns to about 70.

  In FIG. 23, an object (not shown) approaches the security camera 11 in the vertical direction along the arrow 192-1, stops, and then moves away from the security camera 11 in the vertical direction along the arrow 192-2. It is a figure which shows a mode.

  FIG. 24 shows waveforms of the detection signals 211-1 and 211-2 and the approach signal 221-1 and the separation signal 221-2 that are output at this time. In this example, since the object does not enter the region 172-1 or 172-2, the output levels of the detection signals 211-1 and 211-2 by the photosensors 124-1 and 124-2 are substantially constant (about 100). ) And does not change. As a result, it can be seen that the object is not moving in the lateral direction (the direction crossing the front of the security camera 11).

  On the other hand, when an object approaching in the vertical direction along the arrow 192-1 enters the region 171 (around time 580 on the time axis), the output level of the approach signal 221-1 output by the microwave sensor 125 is It has risen to about 250. Thereafter, when the object reaches a position 196 that is closest to the security camera 11 (near time 620 on the time axis), the output level of the approach signal 221-1 returns to about 70. At approximately the same timing, the object is separated in the vertical direction along the arrow 192-2, so that the output level of the separation signal 221-2 is increased to about 250. When the object further moves away in the vertical direction and goes out of the region 171 (near time 700 on the time axis), the output level of the separation signal 221-2 returns to about 70.

  Thus, it can be seen that the object does not move in the horizontal direction, approaches in the vertical direction, and then leaves.

  As described above, the detection signal of the two photo sensors and one microwave sensor allows the object to approach the object regardless of whether it moves in front of the security camera 11 in the horizontal direction or in the vertical direction. Alternatively, separation can be accurately detected. Furthermore, when the object moves in the horizontal direction, it can be accurately detected whether the object is moving from left to right or right to left.

  Next, the object detection processing by the detection unit 151 will be described with reference to the flowchart of FIG.

  In step S1, the detection unit 151 monitors the output of the photosensor 124 and determines whether or not the photosensor 124 has reacted. As described above with reference to FIG. 18 or FIG. 20, when the photo sensor 124 detects an object, the output value of the detection signal is changed. When the output value of the detection signal of the photo sensor 124 changes to a predetermined threshold value or more that is set in advance, it is determined in step S1 that the photo sensor 124 has reacted.

  If it is determined in step S1 that the photosensor 124 has not reacted, the process proceeds to step S2, and the detection unit 151 monitors the output of the microwave sensor 125 to determine whether the microwave sensor 125 has reacted. To do. As described above with reference to FIG. 22 or FIG. 24, the microwave sensor 125 changes the output value of the approach signal or the separation signal when an object is detected. The detection unit 151 determines that the microwave sensor 125 has reacted in step S2 when the output value of the approach signal or the separation signal changes to a predetermined threshold value or more.

  If it is determined in step S2 that the microwave sensor 125 is not responding, the process returns to step S1.

  If it is determined in step S2 that the microwave sensor 125 has reacted, the process proceeds to step S3, and the detection unit 151 causes the microwave sensor 125 to measure the velocity of the object based on the Doppler effect of the reflected wave. Here, when the speed at which the object approaches the microwave sensor 125 is greater than 0, it is determined that the object approaches, and an approach signal is output. On the other hand, when the speed at which the object approaches the microwave sensor 125 is smaller than 0, it is determined that the object is separated and a separation signal is output.

  In step S4, the detection unit 151 determines whether or not the output signal from the microwave sensor 125 is an approach signal.

  If it is determined in step S4 that the detected signal is an approach signal (the object approaches), the detection unit 151 proceeds to step S5 and detects the approach of the object in the vertical direction. That is, at this time, since it is determined in step S1 that the photosensor 124 has not reacted, as described above with reference to FIG. 24, the object does not move in the horizontal direction, but in the vertical direction. It is determined that it has moved to. Then, the detection unit 151 outputs “approach in the vertical direction” to the processing unit 152 as detection information.

  On the other hand, when it is determined in step S4 that the detected signal is not the approach signal, that is, when the separation signal is detected (the object is separated), the detection unit 151 proceeds to step S6, and the object Detect vertical separation. At this time, since it is determined in step S1 that the photosensor 124 has not reacted, it is determined that the object is moving in the vertical direction. Then, the detection unit 151 outputs “longitudinal separation” to the processing unit 152 as detection information.

  When it is determined in step S1 that the photosensor 124 has reacted, in step S7, the detection unit 151 determines whether or not the microwave sensor 125 has reacted, and determines that the microwave sensor 125 has reacted. Wait until. If it is determined in step S7 that the microwave sensor 125 has reacted, the process proceeds to step S8, and the detection unit 151 causes the microwave sensor 125 to measure the velocity of the object based on the Doppler effect of the reflected wave. As in the case of step S3, when the speed at which the object approaches the microwave sensor 125 is greater than 0, an approach signal is output. On the other hand, when the speed at which the object approaches the microwave sensor 125 is smaller than 0, a separation signal is output.

  In step S <b> 9, the detection unit 151 determines whether an approach signal output from the microwave sensor 125 is detected.

  If it is determined in step S9 that an approach signal has been detected, the detection unit 151 proceeds to step S10 and detects a lateral approach. At this time, since it is determined in step S1 that the photosensor 124 has reacted, it is determined that the object is moving in the lateral direction as described above with reference to FIG. Then, “approach from the right” or “approach from the left” is output to the processing unit 152 as the detection information.

  On the other hand, when it is determined in step S9 that no approach signal is detected, that is, when a separation signal is detected, the detection unit 151 proceeds to step S11 and detects separation in the horizontal direction. At this time, since it is determined in step S1 that the photosensor 124 has reacted, it is also determined that the object is moving in the lateral direction. Then, “separation to the right” or “separation to the left” is output to the processing unit 152 as the detection information.

  After step S10 or S11, in step S12, the detection unit 151 determines the moving direction. For example, in step S1, if it is determined that the left photosensor 124-1 has reacted and then it is determined that the right photosensor 124-2 has not reacted, the object is indicated by an arrow 196-1 in FIG. As shown, it is considered that the camera is approaching or moving away from the security camera 11 from an oblique left direction. Therefore, the detection unit 151 detects “oblique left” as the moving direction of the object.

  In Step S1, when it is determined that the right photosensor 124-2 has reacted and then it is determined that the left photosensor 124-1 has not reacted, the object is indicated by an arrow 196-2 in FIG. As shown, it is considered that the camera is approaching or moving away from the security camera 11 from the diagonally right direction. Therefore, the detection unit 151 detects “oblique right” as the moving direction of the object.

  On the other hand, when it is determined in step S1 that both the photosensors 124-1 and 124-2 have reacted, the object crosses the front of the security camera 11 as indicated by an arrow 196-3 in FIG. It is thought that it moved to. Furthermore, it can be determined whether the object is moving from right to left or from left to right depending on which of the photosensors 124-1 and 124-2 has reacted first. . Therefore, the detection unit 151 detects “left to right” or “right to left” as the moving direction of the object.

  After the process of step S5, S6, S10, or S11, the process returns to step S1, and the subsequent processes are repeatedly executed.

  In this way, the movement of the object is detected based on the detection signal of the photo sensor 124 or the microwave sensor 125.

  Next, camera control processing by the processing unit 152 will be described with reference to the flowchart of FIG.

  In step S31, the processing unit 152 determines whether an approach or separation is detected, and waits until it is determined that an approach or separation is detected. As described above with reference to FIG. 25, the detection unit 151 outputs detection information to the processing unit 152. When the processing unit 152 acquires the detection information, it is determined in step S31 that an approach or separation has been detected.

  If it is determined in step S31 that an approach or separation has been detected, the process proceeds to step S32, and the processing unit 152 turns on the video camera 122, the microphone 123, and the communication unit 126. Thus, power is supplied from the power supply unit 127 to each unit.

  In step S33, the processing unit 152 determines an approaching or leaving pattern. At this time, the approach or separation is determined based on the detection information described above. As the approach or separation pattern, for example, “approach in the vertical direction”, “separation in the vertical direction” or the like may be determined as in the detection information, or a more accurate (detailed) pattern is determined. You may make it do. For example, “rapid approach from the right”, “gradual separation to the left”, etc. are determined based on the detection information and the speed of the object measured by the microwave sensor (the processing in step S3 or S8 in FIG. 25). You may be made to do.

  In step S34, the processing unit 152 receives the image captured by the video camera 122, the sound collected by the microphone 123, and the approach or separation pattern determined in step S33 via the communication unit 126. 12 is transmitted (transmitted).

  In step S35, the processing unit 152 determines whether or not there is a transmission continuation command from the user. The image and sound transmitted in step S34 are output to the display and speaker of the receiver 12. The user can confirm the output image and sound and command the continuation of transmission. The command for transmission is input by, for example, operating the input unit (not shown) of the receiver 12 by the user, and the input command is transmitted and received by the communication unit 126 of the security camera 11.

  In step S35, when it is determined that there is a transmission continuation command from the user, the process proceeds to step S36, and the processing unit 152 determines whether or not a predetermined time (for example, 30 seconds) has elapsed, and has not yet elapsed. If it is determined, the process returns to step S31 and the subsequent processing is repeatedly executed. On the other hand, when it is determined in step S36 that the predetermined time has elapsed, the process proceeds to step S37, and the processing unit 152 turns off the power of the video camera 122, the microphone 123, and the communication unit 126. Thereafter, the process returns to step S31.

  In step S35, when it is determined that there is no transmission continuation command from the user, the process proceeds to step S38, and the processing unit 152 stores the feature amount. The feature amount may be generated based on the brightness, color difference or motion of the image captured by the video camera 122, or the frequency of the sound acquired by the microphone 123, or the photo sensor 124 and the microwave sensor. It may be generated based on 125 detection signals.

  If it is determined in step S35 that there has been no transmission continuation command from the user, the user has determined that the image and the sound do not need to be transmitted, so the feature quantities of the image and the sound are stored. Thus, when video and audio with similar feature amounts are detected next time, the power consumption of the security camera 11 can be further suppressed by performing control so that the image and audio are not transmitted.

  In this example, it is determined whether or not there has been a transmission continuation command from the user in step S35. However, in step S35, it may be determined whether or not there is a transmission unnecessary command from the user. In this case, if it is determined in step S35 that there is a transmission unnecessary command from the user, the feature amount is stored in step S38.

  In this example, if it is determined in step S31 that an approach or separation has been detected, the video camera 122, the microphone 123, and the communication unit 126 are turned on in step S32. In S31, it is determined whether or not specific detection information (for example, “approach in the vertical direction” or “separation in the horizontal direction”) has been acquired. If it is determined that the detection information has been acquired, in step S32, The video camera 122, the microphone 123, and the communication unit 126 may be turned on. By doing in this way, power consumption can be further suppressed.

  In this manner, the video camera 122, the microphone 123, and the communication unit 126 are driven based on the detection information from the detection unit 151, and an image, sound, and an approach or separation pattern are transmitted to the receiver 12.

  In the above, an example in which two photo sensors are attached to the security camera 11 has been described, but the number of photo sensors is not limited to two.

  FIG. 29 is a diagram illustrating another configuration example of the security camera 11. This figure corresponds to FIG. 16A, and common portions are denoted by the same reference numerals. In this example, a photosensor 124-3 is provided between the photosensors 124-1 and 124-2. That is, unlike the case of FIG. 16A, three photosensors are provided.

  With reference to FIGS. 30 to 33, how the movement of an object is detected by three photosensors will be described.

  FIG. 30 is a diagram showing a state in which an object (not shown) in front of the security camera 11 moves laterally from left to right in the figure, as in FIG. In this case, the respective detection signals are output by the photosensors 124-1, 124-2, and 124-3 attached to the security camera 11.

  Unlike the case of FIG. 17, when an object that has moved from the left in the drawing enters the region 172-3, the photosensor 124-3 detects light emitted from the object, and the detection signal of the photosensor 124-3 is detected. The output value changes. The operations of the photosensors 124-1 and 124-2 are the same as those in FIG.

  In FIG. 31, similarly to FIG. 18, the vertical axis represents the output value, the horizontal axis represents time, the detection signal 211-1 by the photosensor 124-1, the detection signal 211-2 by the photosensor 124-2, and the photosensor 124. FIG. 3 is a diagram illustrating a waveform of a detection signal 211-3 based on -3.

  Unlike the case of FIG. 18, when an object enters the area 172-3 (around time 130 on the time axis), the output level of the detection signal 211-3 drops to about 60, and then the object moves to the area 172-2. 3 (around time 150 on the time axis), the output level of the detection signal 211-3 has returned to about 100. The waveforms of the detection signals 211-1 and 211-2 are the same as those in FIG.

  FIG. 32 is a diagram showing a state in which an object (not shown) in front of the security camera 11 moves in the horizontal direction from right to left in the figure, contrary to the case of FIG. 30, as in FIG. In this case, the detection signals by the photosensors 124-1, 124-2, and 124-3 have waveforms as shown in FIG.

  FIG. 33 is a diagram corresponding to FIG. 20, but unlike the case of FIG. 20, when an object enters the region 172-3 (near time 130 on the time axis), the output level of the detection signal 211-3 is When the object falls outside the region 172-3 (around time 140 on the time axis), the output level of the detection signal 211-3 returns to about 100. The waveforms of the detection signals 211-1 and 211-2 are the same as those in FIG.

  In this way, from the left to the right of the object (left) according to the detection signals output from the three photosensors 124-1, 124-2, and 124-3 attached to the left, right, and center of the security camera 11. From FIG. 17 to FIG. 20 (in the case of two photosensors), whether it has moved from right to left (from right to center, from center to left) or from right to left. In comparison, the determination can be made more accurately.

  Next, how the movement of the object is detected by the photo sensor and the microwave sensor will be described with reference to FIGS. FIG. 34 is a diagram illustrating how an object moves from left to right in front of the security camera 11 as in the case of FIG. The operations of the photosensors 124-1 and 124-2 and the operation of the microwave sensor 125 are the same as those in FIG. 21. However, when an object enters the region 172-3, a detection signal from the photosensor 124-3 is detected. The output value of changes. In this example, it is assumed that the region 171 where the microwave sensor 125 detects an object and the region 172-3 where the photosensor 124-3 detects an object are the same.

  35, similarly to FIG. 22, the vertical axis represents the output value, the horizontal axis represents time, the detection signal 211-1 by the photosensor 124-1, the detection signal 211-2 by the photosensor 124-2, and the photosensor 124-. 3 is a diagram illustrating waveforms of a detection signal 221-3 by 3 and superimposedly showing waveforms of an approach signal 221-1 and a separation signal 221-2 by the microwave sensor 125. FIG.

  Since the movements of the detection signals 211-1, 211-2, the approach signal 221-1, and the separation signal 221-2 are the same as those in FIG. 22, the description thereof is omitted. However, unlike the case of FIG. 22, when the object reaches near the center of the region 172-3 (171) (near the time axis 130), the output level of the detection signal 211-3 by the photosensor 124-3 is about 60. It is down to. As a result, compared with the case of FIG. 22 (in the case of two photosensors), it can be determined more accurately that the object is approaching the vicinity of the center of the security camera 11.

  In FIG. 36, similarly to FIG. 23, an object (not shown) approaches the security camera 11 in the vertical direction along the arrow 192-1, and then moves away from the security camera 11 in the vertical direction along the arrow 192-2. It is a figure which shows a mode that it does.

  The waveforms of the detection signals 211-1, 211-2 and 211-3, the approach signal 221-1 and the separation signal 221-2 output at this time are shown in FIG. This figure corresponds to FIG. 24, but unlike the case of FIG. 24, when an object enters the region 172-3 (around time 580 to 700 on the time axis), a detection signal by the photosensor 124-3. The output level of 211-3 has changed. Thereby, compared with the case of FIG. 24 (in the case of two photosensors), the approach or separation of the object can be determined more accurately. For example, by measuring the output level of the detection signal 211-3, it is possible to more accurately determine how close or away the object is with respect to the security camera 11.

  It does not matter whether the above-described series of processing is realized by hardware or software. When the above-described series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, a general-purpose personal computer as shown in FIG. 38 is installed from a network or a recording medium.

  In FIG. 38, a CPU (Central Processing Unit) 901 executes various processes according to a program stored in a ROM (Read Only Memory) 902 or a program loaded from a storage unit 908 to a RAM (Random Access Memory) 903. To do. The RAM 903 also appropriately stores data necessary for the CPU 901 to execute various processes.

  The CPU 901, ROM 902, and RAM 903 are connected to each other via a bus 904. An input / output interface 905 is also connected to the bus 904.

  The input / output interface 905 includes an input unit 906 including a keyboard and a mouse, a display (display unit) including a CRT (Cathode Ray Tube) and an LCD (Liquid Crystal display), an output unit 907 including a speaker, a hard disk, and the like A storage unit 908 composed of a communication unit 909 composed of a modem and a terminal adapter is connected. The communication unit 909 performs communication processing via a network such as the Internet.

  A drive 910 is also connected to the input / output interface 905 as necessary. For example, a removable medium 911 is mounted on the drive 910 as a recording medium on which the program of the present invention is recorded, and read from them. A computer program is installed in the storage unit 908 as necessary.

  Note that the steps of executing the series of processes described above in this specification are performed in parallel or individually even if they are not necessarily processed in time series, as well as processes performed in time series in the order described. The processing to be performed is also included.
