Description

  The present invention relates to a technique for distributing image data obtained by an imaging means at each preset position.

  2. Description of the Related Art Conventionally, a network camera system is known in which video from an imaging device is transferred to a PC (Personal Computer) via a network and displayed on a monitor. There is also a network camera system having an imaging device in which rotation in a pan (horizontal) direction and a tilt (vertical) direction is controlled while checking a monitor.

  This type of network system is used in various situations such as commercial facilities such as convenience stores and supermarkets, public facilities such as stations and parks, and transportation facilities such as parking lots and expressways. Since an imaging device can be installed in a remote place and the imaging device can be operated from a remote location, a plurality of locations can be monitored by a single monitor.

  In the case of monitoring a plurality of locations, a preset function is known in which setting information on the pan direction and tilt direction of each location is stored, and each location is visited sequentially. By using this function, the monitor can always monitor the target location without manually moving the imaging device. However, when the preset function is used, each drive speed during the movement from the first designated position to the second designated position is generally performed at a high speed. I feel uncomfortable.

  In addition, when an abnormality occurs outside the place specified by the preset function, the user may not be aware of the abnormality. As a countermeasure, it is conceivable to increase the preset designated position. However, if there are many places to set, attention of the position that the user really wants to monitor is neglected.

  In order to solve the above problems, Patent Document 1 discloses a technique for transmitting a still image during a period of panning or tilting. Patent Document 2 discloses a technique for switching to a stationary monitoring operation when a motion is detected from an image captured by a monitoring camera during automatic monitoring.

JP 2001-86486 A JP 2009-188975 A

  However, since the technique disclosed in Patent Document 1 keeps flowing a still image at the stop position, the image is not updated at any position other than the stop position, so that attention is reduced. The technique disclosed in Patent Document 2 is switched to a stationary monitoring operation when motion is detected at a preset position during automatic monitoring, but there is a concern that monitoring other than the preset position may be neglected.

  Therefore, an object of the present invention is to suppress monitoring while suppressing the bandwidth of the network.

The imaging apparatus of the present invention captures an image between an n (n: any natural number) preset position and an (n + 1) th preset position that distributes image data obtained by the imaging means in a state where movement in the imaging direction is stopped. Setting means for setting a sub-preset position for distributing image data obtained by the image pickup means without stopping movement in the direction , and the image pickup means at positions other than the preset position and the sub-preset position. And control means for controlling not to distribute the image data.

  According to the present invention, it is possible to suppress monitoring while suppressing the bandwidth of the network.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments to which the invention is applied will be described in detail with reference to the accompanying drawings.

  First, a first embodiment of the present invention will be described. FIG. 1 is a diagram illustrating a configuration of a network camera system including an imaging apparatus according to the first embodiment of the present invention. As shown in FIG. 1, an imaging apparatus 19 according to the present embodiment includes an imaging optical system 1, an imaging element 2 that converts incident light into electric charges, an A / D conversion unit 3, an image processing unit 5, and a signal control unit 6. Including a control unit 4, an encoder 7, a command receiving unit 8, a network communication unit 9, a storage unit 11 including a first storage unit 12 and a second storage unit 13, a pan / tilt control unit 14, and a pan mechanism 17 A mechanism unit 15 including a tilt mechanism 16 is provided. The imaging device 19 is connected to the input / output device 10 via the network 18.

  The image sensor 2 that receives light collected by the imaging optical system 1 accumulates electric charges according to the amount of received light by photoelectric conversion. The A / D converter 3 converts the analog signal output from the image sensor 2 into a digital signal. The image data of the digital signal output from the A / D conversion unit 3 is output to the control unit 4. The image processing unit 5 of the control unit 4 performs processing for improving the image quality of the image data input from the A / D conversion unit 3. Further, the image processing unit 5 outputs a reset signal for clearing the accumulated charge to the image sensor 2.

  The signal control unit 6 generates image data having a size necessary for display on the input / output device 10. The encoder 7 performs encoding processing such as compression processing of image data, and outputs the image data after the encoding processing to the network communication unit 9. The network communication unit 9 outputs the image data generated by the imaging device 19 to the network 18. The image data output to the network 18 is input to the input / output device 10. The input / output device 10 includes a display device, and functions as a viewer that presents the image data to the user by displaying the image data on the display device.

  A command generated by the user operating the operation screen on the input / output device 10 is input from the input / output device 10 to the network communication unit 9 of the imaging device 19 via the network 18 and via the command receiving unit 8. Is output to the signal controller 6. The signal control unit 6 controls the image sensor 2 according to the input command.

  The storage unit 11 includes a first storage unit 12 and a second storage unit 13. The first storage unit 12 is a storage unit that writes data to a designated address and reads data from the designated address. The second storage unit 13 is a storage unit that holds nonvolatile data and reads data at an address designated from the nonvolatile data.

  In the present embodiment, the first storage unit 12 is composed of SDRAM. Since SDRAM can perform high-speed writing and reading, it stores programs and data executed by each control unit and is also used as a work area for executing various programs. In the present embodiment, the second storage unit 13 is configured by a nonvolatile storage element such as a flash memory. The nonvolatile storage element is used as a permanent storage area for various programs and data.

  The pan / tilt control unit 14 performs pan and tilt control on the mechanism unit 15. That is, the pan / tilt control unit 14 gives an instruction to the mechanism unit 15 to drive in the pan (left / right) direction and tilt (up / down) direction based on the data given from the signal control unit 6. The pan direction instruction is given to the pan mechanism 17 of the mechanism unit 15, and the tilt direction instruction is given to the tilt mechanism 16 of the mechanism unit 15.

  FIG. 2 is a diagram for explaining an example of patrol by the network camera system shown in FIG. In FIG. 2, an area “A” 201 and an area “B” 202 are preset positions, and an area “1” 211, an area “2” 212, and an area “3” 213 are sub-preset positions. At the preset position, monitoring is performed by distributing image data while the imaging device 19 stops patrol, and at the sub-preset position, monitoring is performed by distributing image data without the imaging device 19 stopping patrol. Is done. Hereinafter, the monitoring function at the preset position is referred to as a preset function, and the monitoring function at the sub-preset position is referred to as a sub-preset function. In FIG. 2, the preset positions are two areas “A” 201 and “B” 202, but it goes without saying that the third and subsequent preset positions can be set.

  When monitoring a supermarket or the like, if the imaging device 19 is installed at a position indicated by 231 in FIG. 2 and it is desired to monitor the region “A” 201 and the region “B” 202 which are door portions, Registers area “A” 201 and area “B” 202 as preset positions. At that time, the user can designate an arbitrary position on the image data displayed on the input / output device 10 such as a PC monitor as a preset position. Here, the imaging device 19 monitors the area “A” 201 and moves the imaging direction to the area “B” 202 when a predetermined time has elapsed. At this time, while the imaging direction moves from the area “A” 201 to the area “B” 202, the panning operation and the tilting operation of the imaging apparatus 19 are controlled so as to move in the movement section 221 in FIG. In addition, the sub-preset position is designated in the movement section 221. In the example of FIG. 2, areas to be noted (area “1” 211, area “2” 212, and area “3” 213 in FIG. 2) such as windows are designated as sub-preset positions. Note that at the sub-preset position, shooting is performed without stopping the pan operation and tilt operation of the imaging device 19.

  FIG. 3A shows an example of the relationship between the waveform of a normal image distribution reset signal and the image data distribution timing. In this example, as shown by 301 in FIG. 3, the image data is distributed at the timing when the image distribution reset signal becomes High. On the other hand, FIG. 3B shows the relationship between the waveform of the image distribution reset signal at the sub-preset position and the image data distribution timing in the present embodiment. That is, 302, 303, and 304 in FIG. 3B indicate the state of the image distribution reset signal in the region “1” 211, the region “2” 212, and the region “3” 213 in the movement section 221 in FIG. Show. Reference numeral 305 denotes image data distribution timing at each sub-preset position. As shown in FIG. 3 (B), the movement section 221 has a network bandwidth by distributing image data only in the areas “1” 211, “2” 212, and “3” 213 which are sub-preset positions. Can be suppressed. Further, the display device in the input / output device 10 displays only the image data distributed at the preset position and the sub-preset position.

  Next, the preset setting process and the sub-preset setting process will be described with reference to FIG. In step S <b> 401, the control unit 4 determines whether the existing setting data regarding the preset position or the sub-preset position is stored in the second storage unit 13. If existing setting data relating to the preset position or the sub-preset position is stored, the process proceeds to step S402. On the other hand, if the existing setting data is not stored, the process proceeds to step S403.

  In step S402, the control unit 4 determines whether to use existing setting data. For example, a GUI (Graphic User Interface) for allowing the input / output device 10 to select whether or not to use existing setting data is displayed, and allows the user to select whether or not to use existing setting data on the GUI. . If the user selects to use the existing setting data, it is determined in step S402 that the existing setting data is to be used, and the process proceeds to step S410. On the other hand, if the user selects not to use the existing setting data, it is determined in step S402 that the existing setting data is not used, and the process proceeds to step S403. In step S410, the control unit 4 starts patrol based on the existing setting data.

  In step S <b> 403, the user designates a preset position using a cursor key (not shown) on the setting screen displayed on the input / output device 10. The control unit 4 controls the pan direction and the tilt direction of the imaging device 19 so that the imaging direction becomes the designated preset position. In step S404, the control unit 4 sets a preset function. That is, the control unit 4 acquires the pan direction angle and the tilt direction angle of the imaging device 19 controlled in step S <b> 403 from the pan / tilt control unit 14 and stores them in the second storage unit 13. At the same time, the control unit 4 sets the time during which the imaging device 19 is stopped at the preset position and the driving speed (movement speed) in the pan direction and the tilt direction after the imaging device 19 starts operating from the preset position. The data is stored in the second storage unit 13. For example, around the image data displayed on the input / output device 10, the stop time of the imaging device 19 at the preset position and the driving speed in the pan direction and the tilt direction after the imaging device 19 starts operating from the preset position. It has a GUI that can be set. Then, when the user operates this GUI, the stop time at the preset position of the imaging device 19 and the driving speed in the pan direction and the tilt direction after the imaging device 19 starts the operation from the preset position are designated. Is possible. As described above, the setting data relating to the preset position is stored in the second storage unit 13, whereby the preset function is set.

  FIG. 5A shows an example of setting data regarding the preset position stored in the second storage unit 13. As shown in FIG. 5A, in the second storage unit 13, the panning and tilting angles of the imaging device 19, the stop time of the imaging device 19 at the preset position, and the imaging device for each preset position. The drive speed in the pan direction and the tilt direction after 19 starts the operation from the preset position is stored.

  In step S405, the control unit 4 determines whether or not the user has designated the preset position. If the preset position is continuously designated by the user, the process returns to step S403, and the preset position is set. On the other hand, when the designation of the preset position by the user is completed, the process proceeds to step S406. In step S406, the control unit 4 determines whether or not to use the sub-preset function. For example, a GUI for allowing the input / output device 10 to select whether to use the sub-preset function is displayed, and the user is allowed to select whether to use the sub-preset function on the GUI. If the user selects to use the sub-preset function, it is determined in step S406 that the sub-preset function is to be used, and the process proceeds to step S407. On the other hand, if the user selects not to use the sub-preset function, it is determined in step S406 that the sub-preset function is not used, and the process proceeds to step S410. In step S410, the control unit 4 starts patrol with the preset function set in step S404.

  In step S407, the user designates a sub-preset position using a cursor key (not shown) on the setting screen displayed on the input / output device 10. The control unit 4 controls the pan direction and the tilt direction of the imaging device 19 so that the imaging direction becomes a designated sub-preset position. In step S408, the control unit 4 sets a sub-preset function. That is, the control unit 4 acquires the pan direction angle and the tilt direction angle of the imaging device 19 controlled in step S407 from the pan / tilt control unit 14 and stores them in the second storage unit 13. As described above, the setting data relating to the sub-preset position is stored in the second storage unit 13, whereby the sub-preset function is set.

  FIG. 5B shows an example of setting data relating to the sub-preset position stored in the second storage unit 13. As shown in FIG. 5B, the second storage unit 13 stores the pan and tilt angles of the imaging device 19 for each sub-preset position.

  In step S409, the control unit 4 determines whether or not the user has designated the sub-preset position. When the sub-preset position is continuously designated by the user, the process returns to step S407, and the sub-preset position is set. On the other hand, when the designation of the sub-preset position by the user is completed, the process proceeds to step S410. In step S410, the control unit 4 starts patrol using the preset function and the sub-preset function.

  Next, a method for setting the driving speed of the imaging device 19 in the pan direction and the tilt direction according to the illuminance in the movement section 221 in FIG. 2 will be described with reference to FIG.

  In step S601, the control unit 4 determines the illuminance in a situation where the preset function and the sub-preset function are already set. Although not shown in FIG. 1, the imaging device 19 according to the present embodiment includes an illuminance meter and can measure illuminance. Here, the illuminance is divided by a certain level (threshold). Here, the case where it divides | segments in three steps is mentioned as an example. Specifically, the illuminance 1 is set to 0.1 to 100 [Lux], the illuminance 2 is set to 100 to 1000 [Lux], and the illuminance 3 is set to 1000 to 10,000 [Lux]. In addition, the lowest 0.1 Lux is an example until it gets tired, and is the minimum illuminance that the imaging device 19 can recognize. If the illuminance is 0.1 to 100 [Lux], the process proceeds to step S602. When the illuminance is 100 to 1000 [Lux], the process proceeds to step S603. When the illuminance is 1000 to 10000 [Lux], the process proceeds to step 604.

  FIG. 7 is a diagram illustrating the relationship between the illuminance of the moving section 221 and the driving speed in the pan direction and the tilt direction. As shown in FIG. 7, in this embodiment, the lower the illuminance, the slower the driving speed is set, and the higher the illuminance is, the faster the driving speed is set. In this way, the drive speed of the imaging device 19 is limited by setting the drive speed in the pan direction and the tilt direction according to the illuminance of the movement section 221. Originally, if the imaging device 19 is driven at high speed in the pan direction and the tilt direction with low illuminance, it is necessary to lengthen the exposure time and increase the amount of light received by the imaging device 2. However, as an effect, image data flows or a lot of noise occurs in the image data. Therefore, in this embodiment, by setting a threshold value for the illuminance and setting the driving speed in the pan direction and the tilt direction of the imaging device 19 according to the illuminance, stable image data can be ensured at any illuminance.

  In step S602, the control unit 4 sets the driving speed in the pan direction and the tilt direction to a low speed. In step S603, the control unit 4 sets the driving speed in the pan direction and the tilt direction to a medium speed. In step S604, the control unit 4 sets the driving speed in the pan direction and the tilt direction to a high speed. In step S605, the control unit 4 sets the shutter speed based on the illuminance determined in step S601. In step S606, the control unit 4 sets the gain of the image data based on the illuminance determined in step S601. Note that the drive speed is set by updating the setting data relating to the preset position shown in FIG. 5A at the drive speed set in step S602, S603, or S604.

  Next, a second embodiment of the present invention will be described. The configuration of the network camera system in the second embodiment is the same as the configuration of the network camera system in the first embodiment shown in FIG.

  In the first embodiment described above, the image data distribution timing is controlled by changing the waveform of the image distribution reset signal. In contrast, in the second embodiment, a normal image distribution reset signal is used, but image data to be distributed is selected. Note that the tour by the preset function and the sub-preset function is the same as the process shown in FIG. 4 in the first embodiment.

  FIG. 8 is a diagram illustrating the relationship between the waveform of the image distribution reset signal and the image data distribution timing in the second embodiment. In the second embodiment, as shown in FIG. 8, an image delivery reset signal similar to the normal image delivery reset signal shown in FIG. 3A is used. However, the timings indicated by 804, 805 and 806 in FIG. 8 are selected as the image data distribution timing. Note that 801, 802, and 803 in the image distribution reset signal shown in FIG. 8 are timings corresponding to the region “1” 211, the region “2” 212, and the region “3” 213 in FIG.

  The image data distribution timing is controlled by the signal control unit 6 in FIG. In the first embodiment, the image distribution reset signal is controlled by the signal control unit 6, but in the second embodiment, the region “1” 211, the region “2” 212, and the region “3” 213 in FIG. Only the image data of is delivered. As a result, it is possible to select image data to be distributed while using a normal image distribution reset signal, and the network bandwidth can be reduced.

  Next, a third embodiment of the present invention will be described. The configuration of the network camera system in the third embodiment is the same as the configuration of the network camera system in the first embodiment shown in FIG. 1, but differs in that an image comparison unit to be described later is added. In the third embodiment, motion detection is performed on the image data acquired at the sub-preset position, and the sub-preset position where the motion is detected from the image data is selected as a preset position. Is.

  Hereinafter, the motion detection process will be described with reference to FIG. Regarding the tour by the preset function and the sub-preset function in the third embodiment, the processing shown in FIG. 4 described as the first embodiment can be applied.

  In step S901, the control unit 4 starts patrol using the preset function and the sub-preset function. In step S902, the image comparison unit detects a difference between the image data.

  In FIG. 2, the imaging device 19 performs a round trip by the preset function, and the imaging device 19 moves when the imaging direction of the imaging device 19 moves from the region “A” 201 to the region “B” 202 and returns to the region “A” 201. The image data is acquired at the sub-preset position of the movement section 221. The image data acquired here is different in the flow of image data because the imaging direction of the imaging device 19 is moving. Even if the shutter speed is high, image data flows. Therefore, the image data stored in the first storage unit 12 is distinguished depending on whether the moving direction is right (R) or left (L).

  FIG. 10 is a diagram for explaining that a flow occurs in image data acquired depending on the imaging direction of the imaging device 19 when the imaging device 19 makes several rounds of patrol by the preset function. That is, at the sub-preset positions 1011, 1012, and 1013 when the imaging direction is clockwise, image data that flows to the right such as 1001 is acquired. At the sub-preset positions 1014, 1015, and 1016 when the imaging direction is counterclockwise, image data that flows to the left such as 1003 is acquired.

  Note that reference numeral 1011 in FIG. 10 denotes a sub for acquiring the image data of the region “1” 211 when the imaging direction is clockwise in the first round-trip (circulation number 1), the second round-trip (circulation number 2),.・ Preset position is shown. Reference numeral 1012 denotes a sub-preset position where the image data of the area “2” 212 is acquired when the imaging direction is clockwise when the first round-trip (circulation number 1), the second round-trip (circulation number 2),. ing. Reference numeral 1013 denotes a sub-preset position where the image data of the region “3” 213 is acquired when the imaging direction is clockwise when the first round-trip (circulation number 1), the second round-trip (circulation number 2),. ing. Reference numeral 1014 denotes a sub-preset position at which the image data of the region “3” 213 is acquired when the imaging direction is counterclockwise in the first round-trip (circulation number 1), the second round-trip (circulation number 2),. ing. Reference numeral 1015 denotes a sub-preset position at which the image data of the area “2” 212 is acquired when the imaging direction is counterclockwise in the first round-trip (circulation number 1), the second round-trip (circulation number 2),. ing. Reference numeral 1016 denotes a sub-preset position at which the image data of the area “1” 211 is acquired when the imaging direction is counterclockwise in the first round-trip (circulation number 1), the second round-trip (circulation number 2),. ing.

  FIG. 11 is a diagram showing sub-preset positions stored in the second storage unit 13. As shown in FIG. 11, in the second storage unit 13, the angle in the pan direction and the tilt direction, the circulation number, and the moving direction (clockwise and counterclockwise) are stored for each sub-preset position. The image comparison unit compares the image data acquired last time and the newly acquired image data at each sub-preset position as needed. In the example of FIG. 10, the image comparison unit compares the image data obtained at the sub-preset position 1011 in the first and second round trips, and compares the sub-preset position 1012 in the first and second round trips. Compare the image data obtained at the sub-preset position 1016 in the first and second round trips, and sequentially obtain the images obtained at the respective sub-preset positions. Compare the data. As a comparison method, background difference is used. Image data at each sub-preset position is obtained by using the image data previously acquired at each sub-preset position as background image data and comparing it with the image data acquired this time at each sub-preset position in pixel units. Motion is detected.

  In step S903, the control unit 4 determines whether or not a motion is detected from the image data by the image comparison unit. If no motion is detected from the image data, the process returns to step S901 to continue the circulation. On the other hand, if a motion is detected from the image data, the process proceeds to step S904. In step S904, the control unit 4 notifies a warning event.

  Regarding the notification of the warning event, the input / output device 10 displays a display indicating the occurrence of the abnormality so that the user can recognize that the abnormality has occurred. For example, a mark is displayed on a part of the image data to be displayed, or the color of the image data is changed. Also, a buzzer may be sounded to notify the user. Further, the time and position when this warning event occurs may be stored in the first storage unit 12 together with the image data so that the user can find it later.

  In step S905, the control unit 4 determines whether or not the position where the movement is detected from the image data by the user is designated as the preset position. When the user determines that the position where the motion is detected from the image data is a position where an abnormality is likely to occur in the future, the user determines the position where the motion is detected as a preset position. If the preset position is not designated, the process proceeds to step S906. On the other hand, when the preset position is designated, the process proceeds to step S907. In step S906, the control unit 4 determines whether to end the process. When it is determined that the process is to be ended, the control unit 4 ends the process. On the other hand, if it is determined not to end the process, the process returns to step S901.

  In step S907, the control unit 4 determines the position where the motion is detected as a preset position. In step S908, the control unit 4 sets a patrol order and a driving speed. In step S909, the control unit 4 updates setting data related to the preset position based on the preset position set in step S907. As a result, the position where the motion is detected is additionally set as a new preset position.

  In the embodiment described above, a sub-preset position is set between the n (n: any natural number) preset position and the (n + 1) -th preset position, and image data is obtained at positions other than the preset position and the sub-preset position. Is not allowed to be delivered. As a result, it is possible to suppress monitoring while suppressing the bandwidth of the network.
