Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The description will be given in the following order.
1. First Embodiment 2. FIG. Second embodiment

<First Embodiment>
[Configuration example]
FIG. 1 illustrates a configuration example of an imaging system (imaging system 1) according to the first embodiment. In this example, the imaging system 1 is a monitoring system that monitors a person or the like. Note that the present invention is not limited to this, and the imaging system 1 can be used for various purposes that use the acquired captured image.

  The imaging system 1 includes a server 10 and a plurality of imaging devices 20 (imaging devices 201 to 207). The server 10 is connected to the Internet NET. In this example, the imaging device 201 is connected to the Internet NET via the gateway 91, the imaging devices 202 to 204 are connected to the Internet NET via the gateway 92, and the imaging devices 205 to 207 are directly connected to the Internet NET. Has been.

  However, the present invention is not limited to this. For example, in this example, the imaging device 201 is connected to the Internet NET via the gateway 91. Instead, for example, instead of the gateway 91, an access point of a wireless LAN (Local Area Network) is provided, and the imaging device 201 may perform wireless communication with this access point and connect to the Internet NET via this access point. In this example, the three imaging devices 20 (imaging devices 202 to 204) are connected to the Internet NET via the gateway 92. Instead, for example, two or less or four or more imaging devices 20 are connected to the gateway. You may connect to the Internet NET via 92.

  In the imaging system 1, each of the imaging devices 20 requests the server 10 to transmit operation setting information ISET that is information about operation settings of the imaging device 20, and acquires the operation setting information ISET from the server 10. . Each of the imaging devices 20 operates based on the operation setting indicated by the acquired operation setting information ISET, acquires a captured image (a high-resolution image PIC2 described later), and stores image data DT including the captured image as server 10. To supply. The server 10 stores image data DT supplied from each of the imaging devices 20. Thereby, for example, the user of the imaging system 1 can check the image data DT stored in the server 10 using a personal computer, a smartphone, or the like.

  For example, the server 10 is an apparatus managed by a trader who operates a monitoring system using the imaging system 1. The server 10 includes a management unit 11, an operation setting information generation unit 12, and a storage unit 13.

  The management unit 11 manages a plurality of imaging devices 20 (imaging devices 201 to 207) in the imaging system 1. The management unit 11 can manage the imaging devices 20 individually, or can group and manage the imaging devices 20. In this example, for example, the management unit 11 manages the imaging device 201 without associating it with other imaging devices 20, and manages the imaging devices 202 to 204 as the imaging devices 20 belonging to one group in association with each other. Yes.

  The operation setting information generation unit 12 generates operation setting information ISET. The operation setting information ISET is information about the operation setting of the imaging device 20. The operation setting information ISET includes setting information SET1 and SET2. The setting information SET1 is information about operation settings when the imaging device 20 performs an imaging operation, and includes information about imaging sensitivity, frame rate, and the like, for example. As will be described later, the setting information SET2 is information regarding operation settings when the imaging apparatus 20 performs moving object detection. For example, the detection threshold value TH that is a determination criterion for moving object detection, and moving object detection in the imaging region of the imaging unit. Information about the detection area RD to be performed, the detection algorithm for moving object detection, and the like is included. The operation setting information generation unit 12 generates the operation setting information ISET when the server 10 receives a transmission request for the operation setting information ISET from the imaging device 20. At this time, the operation setting information generation unit 12 generates operation setting information ISET corresponding to the date and time, as will be described later.

  The storage unit 13 stores image data DT (a high-resolution image PIC2 described later) supplied from the imaging device 20 in association with the imaging device 20 that transmitted the image data DT.

  With this configuration, when the server 10 receives a transmission request for the operation setting information ISET from the imaging device 20, the operation setting information generation unit 12 generates the operation setting information ISET. Then, the server 10 transmits the operation setting information ISET generated by the operation setting information generation unit 12 to the imaging device 20 that has requested transmission of the operation setting information ISET. Further, when the server 10 receives the image data DT from the imaging device 20, the storage unit 13 stores the image data DT in association with the imaging device 20 that transmitted the image data DT. Yes.

  Each of the plurality of imaging devices 20 (imaging devices 201 to 207) is installed, for example, in front of the entrance of an individual house, or in a public place such as a shopping street or a road.

  FIG. 2 illustrates a configuration example of the imaging device 20. The imaging device 20 includes an imaging device 21, an image signal processor (ISP) 28, and a communication unit 29.

  The imaging device 21 is a device that performs an imaging operation, and is configured using, for example, a CIS (CMOS (Complementary Metal Oxide Semiconductor) Image Sensor). The imaging device 21 may be composed of, for example, one chip or a plurality of chips. The imaging device 21 includes an imaging unit 30, a processing unit 40, and a storage unit 50.

  The imaging unit 30 includes a pixel array 31, a scanning unit 32, a reading unit 33, an image generation unit 34, and a control unit 35.

  The pixel array 31 has a plurality of imaging pixels P arranged in a matrix. The imaging pixel P has a photodiode and generates a pixel signal SIG corresponding to the amount of received light. The scanning unit 32 sequentially drives the plurality of imaging pixels P in the pixel array 31 in units of lines, for example, based on an instruction from the control unit 35, and includes, for example, a shift register. The reading unit 33 performs AD (Analog to Digital) conversion based on the pixel signal SIG output from the pixel array 31. The image generation unit 34 generates a captured image based on the AD conversion result in the reading unit 33.

  The control unit 35 controls the operation of the imaging unit 30 by controlling the operations of the scanning unit 32, the reading unit 33, and the image generation unit 34. At that time, the control unit 35 sets the imaging sensitivity, the frame rate, and the like based on the setting information SET1 included in the operation setting information ISET stored in the storage unit 50. Thereby, the imaging device 21 performs an imaging operation based on the setting information SET1.

  The control unit 35 also has a function of controlling the operation of the imaging unit 30 based on an instruction about the operation mode M of the imaging unit 30 supplied from an operation mode setting unit 42 (described later) of the processing unit 40. doing. The imaging unit 30 has two operation modes M (operation modes M1 and M2).

  The operation mode M1 acquires an image with a low resolution (low resolution image PIC1). The operation mode M1 is a mode in which, for example, a part of the plurality of imaging pixels P included in the pixel array 31 is thinned and operated. The imaging unit 30 operates in this operation mode M1, thereby reducing power consumption. Can be reduced. However, the present invention is not limited to this, and in the operation mode M1, the imaging unit 30 may acquire the low-resolution image PIC1 by operating a plurality of imaging pixels P, for example. The imaging device 21 performs moving object detection based on the low-resolution image PIC1.

  The operation mode M2 acquires an image with a high resolution (high resolution image PIC2). For example, the operation mode M2 is a mode in which all of the plurality of imaging pixels P included in the pixel array 31 are operated. The imaging device 20 supplies the high-resolution image PIC2 to the server 10.

  The imaging unit 30 thus has two operation modes M. Based on an instruction from an operation mode setting unit 42 (described later), the control unit 35 controls the scanning unit 32, the reading unit 33, and the image generation unit 34 so that the imaging unit 30 operates in the designated operation mode M. It is designed to control the operation.

  The processing unit 40 includes a moving object detection unit 41, an operation mode setting unit 42, and an update processing unit 43. The processing unit 40 is configured using, for example, a CPU (Central Processing Unit).

  The moving object detection unit 41 performs moving object detection by detecting the presence or absence of a moving object based on the low-resolution image PIC1. Specifically, as described later, the moving object detection unit 41 sets the low resolution image PIC1 as the reference image PREF at a certain timing, and compares the acquired low resolution image PIC1 with the reference image PREF. , Moving object detection. At that time, for example, the moving object detection unit 41 performs detection of a moving object in the imaging region based on the detection threshold TH that is a determination criterion for moving object detection based on the setting information SET2 included in the operation setting information ISET stored in the storage unit 50 A detection region RD, a detection algorithm for moving object detection, etc. are set. Thereby, the moving body detection part 41 performs a moving body detection based on this setting information SET2.

  The operation mode setting unit 42 sets the operation mode M of the imaging unit 30 based on the result of moving object detection by the moving object detection unit 41.

  The update processing unit 43 performs update processing for updating the operation setting information ISET. Specifically, the update processing unit 43 operates with respect to the server 10 using the communication unit 29, for example, every time a predetermined length of time elapses based on the date and time information of the processing unit 40, for example. Requests transmission of the setting information ISET. The update processing unit 43 stores the operation setting information ISET transmitted from the server 10 in the storage unit 50.

  The storage unit 50 stores the reference image PREF and the operation setting information ISET. The storage unit 50 is configured using, for example, a RAM (Random Access Memory). The reference image PREF is generated when the moving object detection unit 41 performs moving object detection. The operation setting information ISET is acquired from the server 10 by the update processing unit 43 performing update processing.

  The image signal processor (ISP) 28 generates image data DT by encoding the high-resolution image PIC2 acquired by the imaging device 21.

  The communication unit 29 communicates with the server 10. Specifically, the communication unit 29 transmits a transmission request for the operation setting information ISET to the server 10 based on an instruction from the update processing unit 43, for example. Then, the communication unit 29 receives the operation setting information ISET transmitted from the server 10 in response to the transmission request. The communication unit 29 transmits image data DT generated by the image signal processor (ISP) 28 to the server 10.

  With this configuration, the update processing unit 43 first requests the server 10 to transmit the operation setting information ISET, and stores the operation setting information ISET transmitted from the server 10 in the storage unit 50. The imaging device 20 operates based on the operation setting information ISET. Specifically, the imaging unit 30 acquires the low-resolution image PIC1 by operating in the operation mode M1. Then, the moving object detection unit 41 performs moving object detection based on the low resolution image PIC1. When a moving object is detected, the imaging unit 30 acquires the high-resolution image PIC2 by operating in the operation mode M2. The image signal processor (ISP) 28 generates image data DT by encoding the high-resolution image PIC2, and the communication unit 29 transmits the image data DT to the server 10.

  Here, the operation mode M1 corresponds to a specific example of “first operation mode” in the present disclosure. The low resolution image PIC1 corresponds to a specific example of “first captured image” in the present disclosure. The operation mode M2 corresponds to a specific example of “second operation mode” in the present disclosure. The high resolution image PIC2 corresponds to a specific example of “second captured image” in the present disclosure. The moving object detection unit 41 corresponds to a specific example of “detection processing unit” in the present disclosure. The update processing unit 43 corresponds to a specific example of “first determination unit” in the present disclosure.

[Operation and Action]
Subsequently, the operation and action of the imaging system 1 of the present embodiment will be described.

(Overview of overall operation)
First, an overall operation overview of the imaging system 1 will be described with reference to FIGS. The update processing unit 43 of the imaging device 20 makes a transmission request for the operation setting information ISET to the server 10. In response to this transmission request, the operation setting information generation unit 12 of the server 10 generates operation setting information ISET corresponding to the date and time. Then, the server 10 transmits the operation setting information ISET to the imaging device 20 that has requested transmission of the operation setting information ISET. The imaging device 20 receives the operation setting information ISET transmitted from the server 10, and the update processing unit 43 stores the operation setting information ISET in the storage unit 50.

  The imaging unit 30 acquires the low resolution image PIC1 by operating in the operation mode M1. Then, the moving object detection unit 41 performs moving object detection based on the low resolution image PIC1. When a moving object is detected, the imaging unit 30 acquires the high-resolution image PIC2 by operating in the operation mode M2. Then, the image signal processor (ISP) 28 generates image data DT by encoding the high-resolution image PIC2, and the communication unit 29 transmits the image data DT to the server 10. The server 10 receives the image data DT and stores the image data DT in the storage unit 13 in association with the imaging device 20 that transmitted the image data DT.

(Detailed operation)
FIG. 3 illustrates an operation example of the imaging system 1.

  First, the update processing unit 43 of the imaging device 20 checks the date and time based on the date and time information included in the processing unit 40 (step S101).

  Next, the update processing unit 43 determines whether or not the operation setting information ISET should be updated (step S102). Specifically, for example, the update processing unit 43 determines that the operation setting information ISET should be updated when a predetermined length of time has elapsed since the operation setting information ISET was updated last time. If it is determined not to update the operation setting information ISET (“N” in step S102), the process proceeds to step S104.

  If it is determined in step S102 that the operation setting information ISET should be updated (“Y” in step S102), the imaging device 20 acquires the operation setting information ISET corresponding to the date and time from the server 10 (step S103). ). Specifically, first, the update processing unit 43 uses the communication unit 29 to make a transmission request for the operation setting information ISET to the server 10. In response to this transmission request, the operation setting information generation unit 12 of the server 10 generates operation setting information ISET corresponding to the date and time. Then, the server 10 transmits the operation setting information ISET to the imaging device 20 that has requested transmission. The update processing unit 43 of the imaging device 20 receives the operation setting information ISET using the communication unit 29 and stores the operation setting information ISET in the storage unit 50.

  Next, the operation mode setting unit 42 sets the operation mode M of the imaging unit 30 to the operation mode M1 (step S104). Thereby, the imaging unit 30 acquires the low-resolution image PIC1 by performing an imaging operation using the setting information SET1 included in the operation setting information ISET stored in the storage unit 50 (step S105).

  Next, the moving object detection unit 41 determines whether or not the reference image PREF should be updated (step S106). Specifically, for example, when the reference image PREF is not updated after acquiring the operation setting information ISET from the server 10, the moving object detection unit 41 determines that the reference image PREF should be updated. For example, the moving object detection unit 41 may determine that the reference image PREF should be updated even when a predetermined length of time has elapsed since the previous update of the reference image PREF. When it is determined that the reference image PREF should be updated (“Y” in step S106), the moving object detection unit 41 stores the low-resolution image PIC1 acquired in step S105 as the reference image PREF in the storage unit 50 (step S106). S107), the process returns to step S101.

  If it is determined in step S106 that the reference image PREF is not to be updated (“N” in step S106), the moving object detection unit 41 is acquired in step S105 and stored in the low-resolution image PIC1 and the storage unit 50. Based on the reference image PREF, the moving object is detected using the setting information SET1 included in the operation setting information ISET stored in the storage unit 50 (step S108). Specifically, the moving object detection unit 41 first generates a difference image PDIFF between the low resolution image PIC1 and the reference image PREF. Then, the moving object detection unit 41 performs moving object detection using a detection algorithm indicated by the setting information SET1 based on the difference image PDIFF. Specifically, for example, the moving object detection unit 41, when the peak value of each pixel value in the detection region RD indicated by the setting information SET1 in the difference image PDIFF is larger than the detection threshold TH indicated by the setting information SET1. Determines that a moving object has been detected. However, the present invention is not limited to this. For example, the moving object detection unit 41 has a detection threshold value indicated by the setting information SET1 in which the average value of the pixel values in the detection region RD indicated by the setting information SET1 in the difference image PDIFF. If it is greater than TH, it may be determined that a moving object has been detected. If no moving object is detected ("N" in step S109), the process returns to step S101.

  When a moving body is detected (“Y” in step S109), the operation mode setting unit 42 sets the operation mode M of the imaging unit 30 to the operation mode M2 (step S110).

  Then, the imaging device 20 acquires the high-resolution image PIC2 during a predetermined length period and transmits the image data DT to the server 10 (step S111). Specifically, the imaging unit 30 performs high-resolution by performing an imaging operation using the setting information SET1 included in the operation setting information ISET stored in the storage unit 50 during a predetermined length of time set in advance. An image PIC2 is acquired. Then, the image signal processor (ISP) 28 generates image data DT by encoding the high-resolution image PIC2, and the communication unit 29 transmits the image data DT to the server 10. The server 10 receives the image data DT, and the storage unit 13 of the server 10 stores the image data DT in association with the imaging device 20 that transmitted the image data DT.

  Then, the process returns to step S101.

  Thus, in the imaging system 1, since the imaging device 20 is configured using the imaging unit 30 having the operation modes M1 and M2, power consumption can be reduced. That is, it is desirable to use a high-resolution image for monitoring, but when the imaging unit 30 always acquires the high-resolution image PIC2, the power consumption may increase. On the other hand, in the imaging system 1, first, the low-resolution image PIC1 is obtained by setting the operation mode M of the imaging unit 30 to the operation mode M1. When a moving object is detected based on the low-resolution image PIC1, the operation mode M of the imaging unit 30 is set to the operation mode M2, thereby acquiring the high-resolution image PIC2. Thereby, in the imaging system 1, power consumption can be reduced effectively.

  In the imaging system 1, the imaging apparatus 20 acquires the operation setting information ISET from the server 10. Specifically, in this example, the imaging device 20 makes a transmission request for the operation setting information ISET to the server 10 each time a predetermined length of time elapses, for example, from the server 10, for example, the date and time The operation setting information ISET corresponding to is acquired. Thereby, in the imaging system 1, since the operation setting information ISET can be changed, the operation can be flexibly performed according to various situations.

  Specifically, for example, the imaging sensitivity or the frame rate of the imaging unit 30 can be changed according to the date and time. Thereby, for example, the imaging sensitivity can be increased at the time of darkening, and the imaging sensitivity can be decreased at the time of brightening. Further, according to the date and time, the detection threshold TH, which is a determination criterion for moving object detection, the detection region RD for performing moving object detection in the imaging region, the detection algorithm for moving object detection, and the like can be changed. Thus, for example, when monitoring is focused on at night, the detection threshold TH is set to a low value at night and the detection threshold TH is set to a high value during the day. It is possible to reduce the risk that the operation mode M is frequently set to the operation mode M2 in the daytime when there are many days. As a result, for example, power consumption can be reduced and the amount of image data DT accumulated in the server 10 can be suppressed. Further, for example, by making the detection threshold TH and the detection algorithm different between weekdays and weekends, it is possible to perform operations according to various situations such as the degree of congestion of people in a monitored place.

[effect]
As described above, in the present embodiment, since the imaging apparatus is configured using the imaging unit having the operation modes M1 and M2, power consumption can be reduced.

  In the present embodiment, since the imaging apparatus acquires the operation setting information from the server, the operation can be flexibly performed according to various situations.

[Modification 1-1]
In the above embodiment, for example, the update processing unit 43 makes a transmission request for the operation setting information ISET to the server 10 based on the date and time information that the processing unit 40 has, but is not limited thereto. Instead, for example, various circuits in the imaging device 20 capable of measuring time may be used. Hereinafter, the imaging system 1A according to the present modification will be described in detail.

  FIG. 4 illustrates a configuration example of the imaging device 20A in the imaging system 1A. The imaging device 20A has an imaging device 21A. The imaging device 21A includes an imaging unit 30A and a processing unit 40A.

  The imaging unit 30A has a control unit 35A. The control unit 35A controls the operation of the imaging unit 30A by controlling the operations of the scanning unit 32, the reading unit 33, and the image generation unit 34, similarly to the control unit 35 according to the above embodiment. . The control unit 35A includes a counter 36A that sequentially increments the count value CNT. The counter 36A resets the count value CNT based on an instruction from an update processing unit 43A (described later) of the processing unit 40A, and the update processing unit 43A can refer to the count value CNT.

  The processing unit 40A includes an update processing unit 43A. For example, the update processing unit 43A resets the counter 36A when receiving the operation setting information ISET from the server 10, and then uses the communication unit 29 when the count value CNT of the counter 36A becomes a predetermined value. Thus, a transmission request for the operation setting information ISET is made to the server 10.

  FIG. 5 illustrates an operation example of the imaging system 1A.

  First, the update processing unit 43A of the imaging device 20A checks the count value CNT of the counter 36A of the control unit 35A (step S121).

  Next, the update processing unit 43A determines whether or not the operation setting information ISET should be updated (step S122). Specifically, for example, the update processing unit 43A determines that the operation setting information ISET should be updated when the count value CNT of the counter 36A confirmed in step S121 becomes a predetermined value.

  If it is determined in step S122 that the operation setting information ISET should be updated (“Y” in step S122), the imaging device 20A acquires the operation setting information ISET corresponding to the date and time from the server 10A (step S103). ). Then, the update processing unit 43A resets the count value CNT of the counter 36A of the control unit 35A (step S123).

  The subsequent operation is the same as in the case of the above embodiment (FIG. 3).

  Even in this configuration, the imaging device 20A can acquire the operation setting information ISET corresponding to the date and time, for example, every time a predetermined length of time elapses, so that it can be flexibly adapted to various situations. The action can be performed.

[Modification 1-2]
In the above embodiment, for example, the operation setting information ISET is obtained every time a predetermined length of time elapses. However, the present invention is not limited to this. Hereinafter, the present modification will be described in detail with reference to a plurality of examples.

  First, an imaging system 1B according to this modification will be described. The imaging system 1B acquires the operation setting information ISET based on environmental values such as temperature, humidity, and atmospheric pressure. The imaging system 1B includes a plurality of imaging devices 20B and a server 10B, similarly to the imaging system 1 (FIG. 1) according to the above embodiment.

  FIG. 6 illustrates a configuration example of the imaging device 20B. The imaging device 20B includes an environment sensor 27B and an imaging device 21B.

  The environmental sensor 27B detects environmental values such as temperature, humidity, atmospheric pressure, and brightness at the location where the imaging device 20B is disposed.

  The imaging device 21B has a processing unit 40B. The processing unit 40B has an update processing unit 43B. For example, the update processing unit 43B uses the communication unit 29 to transmit the operation setting information ISET to the server 10B when environmental values such as temperature, humidity, atmospheric pressure, and brightness detected by the environment sensor 27B change. While making a transmission request, the communication unit 29 is used to supply information about the environmental value to the server 10B.

  The server 10B has an operation setting information generation unit 12B as in the case of the above embodiment (FIG. 1). The operation setting information generation unit 12B generates the operation setting information ISET when the server 10B receives a transmission request for the operation setting information ISET from the imaging device 20B. At that time, the operation setting information generation unit 12B generates the operation setting information ISET corresponding to the environment value based on the information about the environment value such as temperature, humidity, atmospheric pressure, and brightness supplied from the imaging device 20B. It is supposed to be.

  FIG. 7 illustrates an operation example of the imaging system 1B.

  First, the update processing unit 43B of the imaging device 20B confirms environmental values such as air temperature, humidity, atmospheric pressure, and brightness detected by the environmental sensor 27B (step S131).

  Next, the update processing unit 43B determines whether or not the operation setting information ISET should be updated (step S132). Specifically, for example, the update processing unit 43B determines that the operation setting information ISET should be updated when environmental values such as temperature, humidity, atmospheric pressure, and brightness confirmed in step S131 change.

  When it is determined in step S132 that the operation setting information ISET should be updated (“Y” in step S132), the imaging device 20B acquires the operation setting information ISET from the server 10B (step S103). Specifically, first, the update processing unit 43B uses the communication unit 29 to make a transmission request for the operation setting information ISET to the server 10B, and the temperature, humidity, atmospheric pressure, and brightness confirmed in step S131. Provides information on environmental values such as In response to this transmission request, the operation setting information generation unit 12B of the server 10B generates operation setting information ISET corresponding to this environment value. Then, the server 10B transmits the operation setting information ISET to the imaging device 20B that has requested transmission. The update processing unit 43B of the imaging device 20B receives the operation setting information ISET using the communication unit 29, and stores the operation setting information ISET in the storage unit 50.

  The subsequent operation is the same as in the case of the above embodiment (FIG. 3).

  As described above, in the imaging system 1B, when the environmental values such as the temperature, humidity, atmospheric pressure, and brightness detected by the environmental sensor 27B change, the imaging device 20B sets the operation according to the environmental value from the server 10B. Since the information ISET is acquired, the operation can be flexibly performed according to various situations. Specifically, for example, the image quality of the captured image can be improved by changing the imaging sensitivity according to the brightness. Further, for example, when the imaging characteristics of the imaging unit 30 change according to the temperature or the like, the image quality can be obtained by obtaining the operation setting information ISET (for example, the setting information SET1) that maintains the characteristics of the imaging characteristics. The risk of changing can be reduced. In addition, for example, when the degree of congestion of a person in a monitored place changes due to, for example, temperature, humidity, atmospheric pressure, or the like, false detection of moving object detection is reduced by changing the detection threshold TH or the detection algorithm. be able to.

  Next, another imaging system 1C according to this modification will be described. The imaging system 1C acquires the operation setting information ISET based on the power supply voltage to the imaging device. The imaging system 1C includes a plurality of imaging devices 20C and a server 10C, similarly to the imaging system 1 (FIG. 1) according to the above embodiment.

  FIG. 8 illustrates a configuration example of the imaging device 20C. The imaging device 20C includes a power supply voltage sensor 28C and an imaging device 21C.

  The power supply voltage sensor 28C detects a power supply voltage to the imaging device 20C. Here, the power supply voltage sensor 28C corresponds to a specific example of “sensor” in the present disclosure.

  The imaging device 21C has a processing unit 40C. The processing unit 40C includes an update processing unit 43C. For example, when the power supply voltage detected by the power supply voltage sensor 28C changes, the update processing unit 43C uses the communication unit 29 to make a transmission request for the operation setting information ISET to the server 10C. Is used to supply information about the power supply voltage to the server 10C.

  The server 10C has an operation setting information generation unit 12C as in the case of the above embodiment (FIG. 1). The operation setting information generation unit 12C generates the operation setting information ISET when the server 10C receives a transmission request for the operation setting information ISET from the imaging device 20C. At this time, the operation setting information generation unit 12C generates operation setting information ISET corresponding to the power supply voltage based on the information about the power supply voltage supplied from the imaging device 20C.

  The operation of the imaging system 1C is the same as the operation of the imaging system 1B (FIG. 7). In this example, the operation setting information ISET is acquired based on the power supply voltage to the imaging device 20C. However, the present invention is not limited to this, and the operation setting information ISET is acquired based on the power supply current. Alternatively, the operation setting information ISET may be acquired based on electrical parameters other than the supply voltage and the supply current.

  Next, another imaging system 1D according to this modification will be described. The imaging system 1D acquires the operation setting information ISET based on the size and movement of the subject. The imaging system 1D includes a plurality of imaging devices 20D and a server 10D, similar to the imaging system 1 (FIG. 1) according to the above embodiment.

  FIG. 9 illustrates a configuration example of the imaging device 20D. The imaging device 20D has an imaging device 21D. The imaging device 21D has a processing unit 40D. The processing unit 40D includes an image analysis unit 44D and an update processing unit 43D.

  For example, the image analysis unit 44D analyzes the size and movement of the moving object based on the low-resolution image PIC1 in which the moving object is detected.

  The update processing unit 43D uses the communication unit 29, for example, every time when a predetermined length of time elapses, for example, based on the date / time information of the processing unit 40, like the update processing unit 43 of the above embodiment. Thus, a transmission request for the operation setting information ISET is made to the server 10D. The update processing unit 43D makes a transmission request for the operation setting information ISET to the server 10D using the communication unit 29 according to the size and movement of the moving object analyzed by the image analysis unit 44D, for example. The communication unit 29 is also used to supply information about the size and movement of the moving object to the server 10D.

  The server 10D has an operation setting information generation unit 12D as in the case of the above embodiment (FIG. 1). When the server 10D receives a transmission request for the operation setting information ISET from the imaging device 20D, the operation setting information generation unit 12D generates the operation setting information ISET corresponding to the date and time. The operation setting information generation unit 12D also has a function of generating operation setting information ISET corresponding to the size and movement of the moving object based on the information about the size and movement of the moving object supplied from the imaging device 20D. ing.

  10A and 10B illustrate an operation example of the imaging system 1D.

  First, the update processing unit 43D of the imaging device 20D confirms the date and time based on the date and time information included in the processing unit 40D (step S101).

  Next, the update processing unit 43D determines whether or not the operation setting information ISET should be updated (step S102). If it is determined not to update the operation setting information ISET (“N” in step S102), the process proceeds to step S104. When it is determined that the operation setting information ISET should be updated (“Y” in step S102), the imaging device 20D acquires the operation setting information ISET corresponding to the date and time from the server 10D (step S103). Then, the process proceeds to step S104.

  Next, the operation mode setting unit 42 sets the operation mode M of the imaging unit 30 to the operation mode M1 (step S104). Thereby, the imaging unit 30 acquires the low-resolution image PIC1 by performing an imaging operation using the setting information SET1 included in the operation setting information ISET stored in the storage unit 50 (step S105).

  Next, the moving object detection unit 41 determines whether or not the reference image PREF should be updated (step S106). When it is determined that the reference image PREF should be updated (“Y” in step S106), the moving object detection unit 41 stores the low-resolution image PIC1 acquired in step S105 as the reference image PREF in the storage unit 50 (step S106). S107), the process returns to step S101.

  If it is determined in step S106 that the reference image PREF is not to be updated (“N” in step S106), the moving object detection unit 41 is acquired in step S105 and stored in the low-resolution image PIC1 and the storage unit 50. Based on the reference image PREF, the moving object is detected using the setting information SET1 included in the operation setting information ISET stored in the storage unit 50 (step S108). If no moving object is detected ("N" in step S109), the process returns to step S101.

  When a moving object is detected (“Y” in step S109), the image analysis unit 44D analyzes the size and movement of the moving object based on the low resolution image PIC1 (step S141).

  Next, the update processing unit 43D determines whether or not the motion setting information ISET should be updated based on the size and movement of the moving object analyzed in step S141 (step S142). If it is determined not to update the operation setting information ISET (“N” in step S142), the process proceeds to step S110.

  If it is determined in step S142 that the operation setting information ISET should be updated (“Y” in step S142), the imaging device 20D acquires the operation setting information ISET corresponding to the size and movement of the moving object from the server 10D. (Step S143). Specifically, first, the update processing unit 43D makes a transmission request for the operation setting information ISET to the server 10D using the communication unit 29, and information on the size and movement of the moving object confirmed in step S141. Supply. In response to this transmission request, the operation setting information generation unit 12D of the server 10D generates operation setting information ISET corresponding to the size and movement of the moving object. Then, the server 10D transmits the operation setting information ISET to the imaging device 20D that has requested transmission. The update processing unit 43D of the imaging device 20D receives the operation setting information ISET using the communication unit 29 and stores the operation setting information ISET in the storage unit 50.

  Next, the operation mode setting unit 42 sets the operation mode M of the imaging unit 30 to the operation mode M2 (step S110).

  Then, the imaging device 20D acquires the high-resolution image PIC2 during a predetermined length period and transmits the image data DT to the server 10D (Step S111). Then, the process returns to step S101.

  As described above, in the imaging system 1D, the imaging apparatus 20D acquires the operation setting information ISET corresponding to the size and movement of the moving object from the server 10D based on the size and movement of the moving object analyzed by the image analysis unit 44D. Since it did in this way, it can operate | move flexibly according to various situations. Specifically, for example, when the motion of the moving object is large, the image quality can be improved by acquiring operation setting information ISET (for example, setting information SET1) that increases the frame rate.

  In this example, the image analysis unit 44D analyzes the size and movement of the moving object based on the low resolution image PIC1, but the present invention is not limited to this, and instead, for example, the high resolution image PIC2 Based on the above, the size and movement of the moving object may be analyzed.

[Modification 1-3]
In the embodiment described above, the setting information SET2 of the operation setting information ISET includes information about the detection area RD that performs moving object detection in the imaging area of the imaging unit 30. In addition, like the imaging unit 30E shown in FIG. 11, the imaging area of the imaging unit 30E may be divided into a plurality of areas AR so that the imaging operation and the stop of the operation can be controlled in area AR units. . In this example, the imaging unit 30E is divided into two semiconductor substrates (an upper substrate 211 and a lower substrate 212). A pixel array 31 is formed on the upper substrate 211. The pixel array 31 is divided into a plurality of (in this example, nine) areas AR, and each area AR includes a plurality of imaging pixels P. A reading unit 33 is formed on the lower substrate 212. Specifically, the AD conversion unit ADC connected to the plurality of imaging pixels P belonging to the area AR is formed in the lower substrate 212 in a region corresponding to the area AR in the upper substrate 211. The upper substrate 211 and the lower substrate 212 are electrically connected by, for example, Cu-Cu bonding. In this example, the pixel array 31 is divided into nine areas AR. However, the present invention is not limited to this. For example, the pixel array 31 may be divided into eight areas or less, or ten or more areas AR. . With this configuration, the imaging unit 30E can control the imaging operation and the stop of the operation for each area AR. As a result, in the imaging device 20E provided with the imaging unit 30E, power consumption can be reduced.

  For example, in the operation mode M1, the imaging device 20E sets an area AR for performing an imaging operation based on information about the detection region RD included in the setting information SET2, and based on the imaging result (low-resolution image PIC1). Moving object detection may be performed. Further, for example, in the operation mode M2, the imaging device 20E sets an area AR in which an imaging operation is performed based on information about the detection area RD included in the setting information SET2, and the imaging result (high resolution image PIC2) is set. You may transmit to the server 10.

  For example, the imaging device 20E may acquire a plurality of operation setting information ISET corresponding to each of the plurality of areas AR from the server 10. Thereby, in the imaging device 20E, since the operation setting can be performed for each area AR, for example, the degree of freedom of the imaging operation can be increased, and the degree of freedom of the motion detection operation can be increased. It is possible to operate flexibly according to various situations.

[Other variations]
Further, two or more of these modifications may be combined.

<2. Second Embodiment>
Next, the imaging system 2 according to the second embodiment will be described. In the present embodiment, the server transmits the operation setting information ISET to the imaging device without receiving an update request from the imaging device. In addition, the same code | symbol is attached | subjected to the substantially same component as the imaging system 1 which concerns on the said 1st Embodiment, and description is abbreviate | omitted suitably.

  FIG. 12 illustrates a configuration example of the imaging system 2. The imaging system 2 includes a server 60 and a plurality of imaging devices 70 (imaging devices 701 to 707).

  The server 60 has an update processing unit 64. For example, the update processing unit 64 makes a generation request for the operation setting information ISET to the operation setting information generation unit 12 every time a predetermined length of time elapses, for example, based on date and time information held by the server 60. Is. Then, the server 60 transmits the operation setting information ISET generated by the operation setting information generation unit 12 to the imaging device 70, respectively. Here, the update processing unit 64 corresponds to a specific example of “second determination unit” in the present disclosure.

FIG. 13 illustrates a configuration example of the imaging device 70. The imaging device 70 has an imaging device 71. The imaging device 71 has a processing unit 80. The processing unit 80 includes a moving object detection unit 41 and an operation mode setting unit 42. That is, the processing unit 80 is obtained by omitting the update processing unit 43 from the processing unit 40 (FIG. 2) according to the above embodiment. The processing unit 80 also has a function of storing the operation setting information ISET transmitted from the server 60 in the storage unit 50.

  FIG. 14 illustrates an operation example of the imaging system 2.

  First, the update processing unit 64 of the server 60 confirms the date and time based on the date and time information that the server 60 has (step S201).

  Next, the update processing unit 64 determines whether or not the operation setting information ISET should be updated (step S202). Specifically, for example, the update processing unit 64 determines that the operation setting information ISET should be updated when a predetermined length of time has elapsed since the operation setting information ISET was updated last time. If it is determined not to update the operation setting information ISET (“N” in step S202), the process proceeds to step S104.

  If it is determined in step S202 that the operation setting information ISET should be updated (“Y” in step S202), the server 60 transmits the operation setting information ISET corresponding to the date and time (step S203). Specifically, first, the operation setting information generation unit 12 of the server 60 generates operation setting information ISET corresponding to the date and time. Then, the server 60 transmits the operation setting information ISET to the imaging device 70. The communication unit 29 of the imaging device 70 receives the operation setting information ISET. Then, the processing unit 80 stores the operation setting information ISET in the storage unit 50.

  The subsequent operation is the same as that in the case of the first embodiment (FIG. 3).

  As described above, in the imaging system 2, the server 60 transmits the operation setting information ISET to the imaging device 70 without receiving an update request from the imaging device 70. Thereby, in the imaging system 2, the server 60 can manage the operation settings of the plurality of imaging devices 70 in the imaging system 2. In particular, in the imaging system 2, for example, various information can be acquired from the plurality of imaging devices 70, so that the operation setting of the imaging device 70 can be performed based on the acquired information. As a result, the imaging system 2 can flexibly operate according to various situations.

  As described above, in the present embodiment, the server transmits the operation setting information to the imaging apparatus, so that the operation can be performed flexibly according to various situations. Other effects are the same as in the case of the first embodiment.

[Modification 2-1]
In the above-described embodiment, for example, the server 60 transmits the operation setting information ISET to the imaging device 70 every time a predetermined length of time elapses. However, the present invention is not limited to this. For example, the server may predict the user's behavior and transmit the operation setting information ISET to the imaging device based on the prediction result. Hereinafter, the imaging system 2A according to the present modification will be described in detail.

  FIG. 15 illustrates a configuration example of the imaging system 2A. The imaging system 2A includes a server 60A. The server 60A includes an action prediction unit 65A and an update processing unit 64A.

  The behavior prediction unit 65 </ b> A predicts human behavior based on the image data DT stored in the storage unit 13. Specifically, the behavior predicting unit 65A predicts the user's behavior based on, for example, the image data DT supplied from the imaging device 70. Here, the behavior prediction unit 65A corresponds to a specific example of a “prediction unit” in the present disclosure.

  The update processing unit 64A determines whether or not the operation setting information ISET should be updated based on the prediction result of the human behavior in the behavior prediction unit 65A. On the other hand, a generation request for the operation setting information ISET is made.

  With this configuration, for example, the behavior prediction unit 65A grasps the behavior pattern of the user based on the image data DT supplied and accumulated from the imaging device 70 disposed at the user's home, and predicts the behavior. Then, the update processing unit 64A makes a generation request for the operation setting information ISET of the imaging device 70, for example, at the time when the user is absent. For example, the operation setting information generation unit 12 sets the detection threshold TH to a low value when the user is absent, and sets the detection threshold TH to a high value when the user is at home. Thereby, in the imaging system 2A, it is possible to focus monitoring in a time zone when the user is absent.

  In this example, the user's behavior pattern is grasped based on the image data DT supplied and accumulated from one imaging device 70, but the present invention is not limited to this, and is supplied and accumulated from a plurality of imaging devices 70. The user's behavior pattern may be grasped based on the image data DT that has been obtained.

  In this example, the behavior prediction unit 65A predicted the user's behavior, but the present invention is not limited to this. For example, the user inputs a user's schedule in advance using a personal computer or a smartphone, and the input Based on the information thus obtained, the update processing unit 64A may make a generation request for the operation setting information ISET.

[Modification 2-2]
For example, the server may generate the operation setting information ISET for one imaging device 70 based on the operations of the plurality of imaging devices 70. Hereinafter, the present modification will be described in detail with some examples.

  FIG. 16 illustrates a configuration example of the imaging system 2B according to the present modification. The imaging system 2B includes a server 60B. The server 60B includes a cooperative operation control unit 66B and an update processing unit 64B.

  The cooperative operation control unit 66B controls, for example, a plurality of imaging devices 70 managed by grouping (in this example, three imaging devices 702 to 704) to operate in cooperation.

  FIG. 17 illustrates an arrangement example of three imaging devices 702 to 704. In this example, three imaging devices 702 to 704 are arranged in this order along the passage 100. Thereby, when the passer-by 101 walks along the passage 100 in a certain direction (upward in FIG. 17), the imaging devices 702 to 704 can sequentially capture the passer-by 101. The cooperative operation control unit 66B has a function of managing whether or not the moving object detection unit 41 of the imaging devices 702 to 704 has detected a moving object, for example.

  The update processing unit 64B requests the operation setting information generating unit 12 to generate the operation setting information ISET based on an instruction from the cooperative operation control unit 66B.

  FIG. 18 illustrates an operation example of the server 60B.

  The cooperative operation control unit 66B of the server 60B confirms whether or not the moving object detection unit 41 of the imaging device 702 has detected a moving object (step S211). If no moving object is detected ("N" in step S211), the process returns to step S211 and repeats step S211 until a moving object is detected.

  In step S211, when the moving object detection unit 41 of the imaging device 702 detects a moving object (“Y” in step S211), the server 60B supplies the operation setting information ISET to the imaging device 703 (step S212). . Specifically, the update processing unit 64B of the server 60B requests the operation setting information generation unit 12 to generate the operation setting information ISET of the imaging device 703. Then, the operation setting information generation unit 12 generates operation setting information ISET for setting the detection threshold TH in the imaging device 703 to a low value. Then, the server 60B supplies the operation setting information ISET to the imaging device 703. That is, since a moving object is detected in the imaging device 702, it is expected that a moving object is detected in the imaging device 703 next. Therefore, in the imaging system 2B, the detection threshold TH in the imaging device 703 is set to a low value so that the imaging device 703 can perform moving object detection.

  Next, the cooperative operation control unit 66B of the server 60B confirms whether or not the moving object detection unit 41 of the imaging device 703 has detected a moving object (step S213). If no moving object is detected ("N" in step S213), the process returns to step S213, and this step S213 is repeated until a moving object is detected.

  In step S213, when the moving object detection unit 41 of the imaging device 703 detects a moving object (“Y” in step S213), the server 60B supplies the operation setting information ISET to the imaging device 704 (step S214). . Specifically, the update processing unit 64B of the server 60B requests the operation setting information generation unit 12 to generate the operation setting information ISET of the imaging device 704. Then, the operation setting information generation unit 12 generates operation setting information ISET for setting the detection threshold TH in the imaging device 704 to a low value. Then, the server 60B supplies the operation setting information ISET to the imaging device 704. That is, since a moving object is detected by the imaging device 703, it is expected that a moving object will be detected next by the imaging device 704. Therefore, in the imaging system 2B, the detection threshold TH in the imaging device 703 is set to a low value so that the imaging device 703 can perform moving object detection.

  Thus, this flow ends.

  As described above, in the imaging system 2B, the operation setting information ISET of a certain imaging device 70 is generated based on the operations of the plurality of imaging devices 70. Therefore, the plurality of imaging devices 70 operate flexibly while cooperating with each other. be able to.

  FIG. 19 illustrates a configuration example of another imaging system 2C according to the present modification. The imaging system 2C includes a server 60C. The server 60C includes a diagnosis unit 67C and an update processing unit 64C.

  The diagnosis unit 67C is for diagnosing whether or not a plurality of imaging devices 70 (three imaging devices 702 to 704 in this example) managed by grouping are operating normally, for example. Specifically, for example, in the example illustrated in FIG. 17, the diagnosis unit 67C diagnoses these imaging devices 70 by managing whether or not the moving object detection unit 41 of the imaging devices 702 to 704 has detected a moving object. It is supposed to be.

  The update processing unit 64C requests the operation setting information generation unit 12 to generate the operation setting information ISET based on an instruction from the diagnosis unit 67C.

  FIG. 20 illustrates an operation example of the server 60C.

  First, the diagnosis unit 67C confirms the number of times that a moving object is detected in a period of a predetermined length in the three imaging devices 702 to 704 (step S221).

  Next, the diagnosis unit 67C confirms whether there is a large difference in the number of times that a moving object is detected in the three imaging devices 702 to 704 (step S222). That is, since the imaging devices 702 to 704 detect the passerby 101 in the passage 100 (FIG. 17), it is expected that the number of times that the moving body is detected in the imaging devices 702 to 704 is substantially equal. Therefore, the diagnosis unit 67C confirms whether there is a large difference in the number of times the moving object is detected in the three imaging devices 702 to 704, so that all of the three imaging devices 702 to 704 operate normally. Check if it is. If there is no significant difference in the number of times that a moving object is detected (“N” in step S222), this flow ends.

  If there is a large difference in the number of times that the moving object is detected in step S222, the diagnosis unit 67C performs a diagnosis process (step S223). Specifically, the diagnosis unit 67C, for example, causes each of the three imaging devices 702 to 704 to operate in the operation mode M1 to acquire the low resolution image PIC1. Then, the diagnosis unit 67C confirms which of the three imaging devices 702 to 704 is not operating normally based on the three low-resolution images PIC1. For example, the diagnosis unit 67C causes each of the three imaging devices 702 to 704 to operate in the operation mode M2 to acquire the high-resolution image PIC2, and to obtain the three high-resolution images PIC2. Diagnosis may be performed based on the above.

  Then, the server 60C supplies the operation setting information ISET to the imaging device 70 whose operation setting is to be changed among the three imaging devices 702 to 704 (step S224). Thereby, in the imaging device 70 to which the operation setting information ISET is supplied, the operation setting is changed. As a result, in this imaging device 70, for example, the imaging sensitivity and the detection threshold TH are adjusted.

  Thus, this flow ends.

  Thus, in the imaging system 2C, the operation setting information ISET of a certain imaging device 70 is generated based on the operations of the plurality of imaging devices 70. For example, the operation setting in the imaging device 70 can be adjusted.

  In this example, the diagnosis unit 67C confirms which of the three imaging devices 702 to 704 is not operating normally based on the three low-resolution images PIC1. For example, a person may determine which imaging device 70 is not operating normally by directly checking the three low-resolution images PIC1.

[Modification 2-3]
For example, the server may generate the operation setting information ISET of the imaging device 70 based on an instruction from another device.
