It has.

  The lens unit 12 is an imaging optical system composed of a plurality of lens groups. The lens unit 12 guides the light flux from the subject to the imaging unit 14. The lens unit 12 may have a built-in focus lens or a zoom lens.

  The imaging unit 14 includes an imaging element 30 and a driving unit 32. The image sensor 30 delivers the acquired pixel signal to the image processing unit 16. The drive unit 32 is a control circuit that controls the drive of the image sensor 30 in accordance with an instruction from the system control unit 24. The specific configuration of the image sensor 30 and the specific drive control of the image sensor 30 by the drive unit 32 will be described later.

  The image processing unit 16 uses the work memory 18 as a work space, performs various image processing on the RAW data composed of pixel signals of each pixel, and generates image data. The image processing unit 16 includes a first image processing unit 16A and a second image processing unit 16B. In the first embodiment, as will be described later, when the moving subject (for example, a person) enters the pixel area of the image sensor 30, the system control unit 24 determines that the moving subject in the pixel area is The included range is set as a variable block (area). Further, the system control unit 24 drives and controls the image sensor 30 so that the fluctuation block is imaged under an imaging condition different from the imaging conditions of all the blocks before the fluctuation block is set. In this case, for example, the first image processing unit 16A performs image processing of signals from pixels included in all blocks, and the second image processing unit 16B performs image processing of signals from pixels included in the fluctuation block. Run.

  The image processing unit 16 performs various image processing. For example, the image processing unit 16 generates an RGB image signal by performing color signal processing (tone correction) on the signal obtained by the image sensor 30. The image processing unit 16 performs image processing such as white balance adjustment, sharpness adjustment, gamma correction, and gradation adjustment on the image signal. Further, the image processing unit 16 performs a process of compressing in a predetermined compression format (JPEG format, MPEG format, etc.) as necessary. The image processing unit 16 outputs the generated image data to the recording unit 22.

  The image processing unit 16 extracts frames at predetermined timings from among a plurality of frames obtained in time series from the imaging unit 14. The image processing unit 16 adds one or more frames to be interpolated between the frames based on the plurality of frames obtained in time series from the imaging unit 14 between the frames. As a result, a moving image with smoother motion can be reproduced during moving image reproduction.

  The work memory 18 temporarily stores image data and the like when image processing by the image processing unit 16 is performed.

  The operation unit 20 is a switch or the like used by a user. The operation unit 20 outputs a signal corresponding to the operation by the user to the system control unit 24. Note that the operation unit 20 may include a touch panel.

  The recording unit 22 has a card slot into which a recording medium such as a memory card can be mounted. The recording unit 22 stores the image data and various data generated by the image processing unit 16 in a recording medium mounted in the card slot. The first recording unit 22A of the recording unit 22 stores the image data and the like generated by the first image processing unit 16A, and the second recording unit 22B stores the image data and the like generated by the second image processing unit 16B. To do. The recording unit 22 has an internal memory. The recording unit 22 can also store the image data and various data generated by the image processing unit 16 in an internal memory.

  The system control unit 24 comprehensively controls the overall processing and operation of the monitoring camera 10. The system control unit 24 includes a CPU (Central Processing Unit) 24A. In the first embodiment, the system control unit 24 divides the imaging surface of the imaging element 30 into a plurality of blocks, and acquires images with different charge accumulation times (or charge accumulation times), frame rates, and gains among the blocks. . Therefore, the system control unit 24 instructs the drive unit 32 on the block position, shape, range, and storage condition for the block. In addition, the system control unit 24 causes the image to be acquired with a different thinning rate between blocks, the number of addition rows or addition columns to which pixel signals are added, and the number of digitization bits. Therefore, the system control unit 24 instructs the drive unit 32 on the imaging conditions for each block (thinning rate, the number of added rows or columns to add pixel signals, and the number of digitization bits). Further, the image processing unit 16 executes image processing under different imaging conditions (control parameters such as color signal processing, white balance adjustment, gradation adjustment, and compression rate) between blocks. Therefore, the system control unit 24 instructs the image processing unit 16 on the imaging conditions for each block (control parameters such as color signal processing, white balance adjustment, gradation adjustment, and compression rate).

  In addition, the system control unit 24 stores the image data generated in the image processing unit 16 in the recording unit 22. Further, the system control unit 24 instructs the communication unit 26 to communicate with the management device 50 via the network 60 (see FIG. 1). The system control unit 24 transmits the image data and the like generated by the image processing unit 16 to the management device 50.

  The illuminometer 28 detects the illuminance around the monitoring camera 10. The detection result of the illuminometer 28 is input to the system control unit 24.

  Next, the image sensor 30 will be described in detail with reference to FIGS. The image sensor 30 of the first embodiment is a stacked image sensor.

  FIG. 3 shows a cross-sectional view of the image sensor 30. As shown in FIG. 3, the imaging element 30 includes an imaging chip 113 that outputs a pixel signal corresponding to incident light, a signal processing chip 111 that processes the pixel signal, and a memory chip 112 that stores the pixel signal. . The imaging chip 113, the signal processing chip 111, and the memory chip 112 are stacked, and are electrically connected to each other by a conductive bump 109 such as copper (Cu).

  In addition, as shown in FIG. 3, incident light is incident mainly in the direction indicated by the white arrow. In the first embodiment, in the imaging chip 113, the surface on the side where incident light is incident is referred to as a back surface.

  The imaging chip 113 is, for example, a back-illuminated MOS image sensor, and includes a PD layer 106, a wiring layer 108, and the like.

  The PD layer 106 is disposed on the back side of the wiring layer 108. The PD layer 106 includes a plurality of photodiodes (Photodiode: PD) 104 that are two-dimensionally arranged and store electric charges according to incident light, and transistors 105 provided corresponding to the PDs 104.

  A filter unit 102 is provided on the incident side of incident light in the PD layer 106 via a passivation film 103. The filter unit 102 includes a color filter. The color filter is a filter that passes a specific wavelength region of visible light, and has a plurality of types that transmit different wavelength regions. The color filter has a specific arrangement corresponding to each PD 104. The arrangement of the color filter will be described later. Note that a set of the filter portion 102, the PD 104, and the transistor 105 forms one pixel. A microlens 101 is provided on the incident light incident side of the filter unit 102 corresponding to each pixel. The microlens 101 condenses incident light toward the corresponding PD 104.

  The wiring layer 108 includes a wiring 107 that transmits the pixel signal from the PD layer 106 to the signal processing chip 111. The wiring 107 may be multilayer, and a passive element and an active element may be provided.

  The signal processing chip 111 has a TSV (Through-Silicon Via) 110 that connects circuits provided on the front surface and the back surface to each other. The TSV 110 may be provided in the peripheral area of the imaging chip 113 or the memory chip 112.

  FIG. 4 is a diagram for explaining a pixel array and a unit group of the imaging chip 113. FIG. 4 is a diagram illustrating a state in which the imaging chip 113 is viewed from the back side. An area where pixels are arranged in the imaging chip 113 is referred to as a pixel area 113A. In the pixel region 113A, 20 million or more pixels are arranged in a matrix. In the example shown in FIG. 4, adjacent 16 pixels of 4 pixels × 4 pixels form one unit group 131. Note that the lattice lines in FIG. 4 indicate a concept in which adjacent pixels are grouped to form a unit group 131. Note that the number of pixels forming the unit group 131 is not limited to this, and may be about 1000, for example, 32 pixels × 64 pixels, or more or less.

  As shown in a partially enlarged view of the pixel area 113A (the lower right diagram in FIG. 4), the unit group 131 has a so-called Bayer arrangement composed of four pixels, ie, green pixels Gb, Gr, blue pixels B, and red pixels R. 4 included. The green pixels Gb and Gr are pixels having a green filter as the filter unit 102 (color filter), and receive light in the green wavelength band of incident light. The blue pixel B is a pixel having a blue filter as the filter unit 102 and receives light in the blue wavelength band. The red pixel R is a pixel having a red filter as the filter unit 102 and receives light in the red wavelength band.

  FIG. 5 is a diagram showing an equivalent circuit diagram of each pixel. In the following description, the pixel is denoted by reference numeral 150. Each pixel 150 includes the PD 104, the transfer transistor 152, the reset transistor 154, the amplification transistor 156, and the selection transistor 158. At least some of these transistors correspond to the transistor 105 in FIG. Further, in each pixel, a reset wiring 300 to which an ON signal of the reset transistor 154 is supplied, a transfer wiring 302 to which an ON signal of the transfer transistor 152 is supplied, a power supply wiring 304 that receives power supply from the power supply Vdd, and a selection transistor 158. A selection wiring 306 to which an ON signal is supplied and an output wiring 308 for outputting a pixel signal are arranged. Hereinafter, each transistor is described as an n-channel FET, but the type of transistor is not limited thereto.

  The source, gate, and drain of the transfer transistor 152 are connected to one end of the PD 104, the transfer wiring 302, and the gate of the amplification transistor 156, respectively. The drain of the reset transistor 154 is connected to the power supply wiring 304, and the source is connected to the gate of the amplification transistor 156. The drain of the amplification transistor 156 is connected to the power supply wiring 304, and the source is connected to the drain of the selection transistor 158. The gate of the selection transistor 158 is connected to the selection wiring 306, and the source is connected to the output wiring 308. The load current source 309 supplies current to the output wiring 308. That is, the output wiring 308 for the selection transistor 158 is formed by a source follower. Note that the load current source 309 may be provided on the imaging chip 113 side or on the signal processing chip 111 side.

  FIG. 6 is a circuit diagram showing the connection relationship of the pixels 150 in the unit group 131. In FIG. 6, transfer wiring and output wiring are shown, but other configurations of each pixel are omitted.

  In the first embodiment, the pixels 150 having the same color filter in the unit group 131 form a pixel group. That is, in the first embodiment, eight pixels G (Gr, Gb) form a G pixel group, four pixels R form an R pixel group, and four pixels B form a B pixel group. .

  Here, the gates of the transfer transistors are commonly connected between a plurality of pixels included in each pixel group. That is, the gates of the transfer transistors of the pixels included in the G pixel group are connected to the common G transfer wiring 330, the gates of the transfer transistors of the pixels included in the R pixel group are connected to the common R transfer wiring 332, and the B pixels The gates of the transfer transistors of the pixels included in the group are connected to a common B transfer wiring 334. Thereby, the drive unit 32 can control the gates of the transfer transistors all at once within the pixel group and independently between the pixel groups.

  In addition, the output side of the selection transistor is connected in common between a plurality of pixels included in each pixel group. That is, the output side of the selection transistor of the pixel of the G pixel group is connected to the common G output wiring 340, the output side of the selection transistor of the pixel of the R pixel group is connected to the common R output wiring 342, and The output side of the selection transistor of the pixel is connected to a common B output wiring 344.

  Although not shown in FIG. 6, the reset wiring and the power supply wiring are common to the unit group 131. In addition, 16 selection wirings are arranged on a one-to-one basis for each pixel, and are connected to the gates of the corresponding selection transistors. Furthermore, a load current source is connected to each output wiring.

  As described above, the driving unit 32 can collectively control the charge accumulation time of each pixel belonging to each pixel group. In addition, the drive unit 32 can accumulate charges for a specific pixel group in a different accumulation time than other pixel groups.

  FIG. 7 is a block diagram illustrating a functional configuration of the image sensor. The analog multiplexer 411 selects eight pixels G in the G pixel group of the unit group 131 in order, and outputs each pixel signal to the G output wiring 320. The pixel signal output via the multiplexer 411 is amplified by the amplifier 416, and the amplified pixel signal is supplied to the correlated double sampling (CDS), analog / digital (Analog) via the G output wiring 320. The signal processing circuit 412 that performs (Digital) conversion performs correlated double sampling signal processing and A / D conversion (conversion from an analog signal to a digital signal). The A / D converted pixel signal is transferred to the demultiplexer 413 via the G output wiring 321 and stored in the pixel memory 414 corresponding to each pixel.

  Similarly, the multiplexers 421 and 431 select the pixels of the R and B pixel groups in the unit group 131 in order, and output the pixel signals of the respective pixels to the output wirings 322 and 324. The pixel signals output to the output wirings 322 and 324 are amplified by the amplifiers 426 and 436, and the signal processing circuits 422 and 432 perform CDS and A / D conversion on the amplified pixel signals. The A / D converted pixel signal is transferred to the demultiplexers 423 and 433 via the output wirings 323 and 325, and stored in the pixel memory 414 corresponding to each pixel.

  Note that each of the multiplexers 411, 421, and 431 is formed on the imaging chip 113 by the selection transistor 158 and the selection wiring 306 in FIG. The amplifiers 416, 426, 436 and the signal processing circuits 412, 422, 432 are formed in the signal processing chip 111. The demultiplexers 413, 423, 433, and the pixel memory 414 are formed in the memory chip 112.

  The arithmetic circuit 415 processes the pixel signal stored in the pixel memory 414 and passes the processed pixel signal to the subsequent image processing unit 16. The arithmetic circuit 415 may be provided in the signal processing chip 111 or may be provided in the memory chip 112. Note that FIG. 6 shows connections for one unit group 131, but actually these exist for each unit group 131 and operate in parallel. However, the arithmetic circuit 415 may not exist for each unit group 131. For example, one arithmetic circuit 415 may perform sequential processing while sequentially referring to the values in the pixel memory 414 corresponding to each unit group 131.

  Next, blocks set in the pixel region 113A (see FIG. 4) of the image sensor 30 will be described. In the first embodiment, the pixel region 113A of the image sensor 30 is divided into a plurality of blocks. The plurality of blocks are defined to include at least one unit group 131 per block. In each block, pixels included in each block are controlled by different control parameters. That is, pixel signals having different control parameters are acquired for a pixel group included in a block and a pixel group included in another block. Examples of the control parameter include a charge accumulation time or accumulation count, a frame rate, a gain, a thinning rate, the number of addition rows or addition columns for adding pixel signals, and the number of digitization bits. Furthermore, the control parameter may be a parameter in image processing after obtaining an image signal from a pixel.

  Here, the charge accumulation time refers to the time from when PD 104 starts to accumulate charge until it ends. The number of times of charge accumulation refers to the number of times the PD 104 accumulates charges per unit time.

  The frame rate is a value representing the number of frames processed (displayed or recorded) per unit time in a moving image. The frame rate is controlled, for example, by controlling the timing (or timing cycle) at which the drive unit 32 applies the reset pulse, the transfer pulse, and the selection pulse to the reset transistor 154, the transfer transistor 152, and the selection transistor 158, respectively. . The unit of the frame rate is represented by fps (Frames Per Second). The higher the frame rate, the smoother the movement of the subject (that is, the object to be imaged) in the moving image.

  Further, the gain means a gain factor (amplification factor) of the amplifiers 416, 426, and 436. By changing this gain, the ISO sensitivity can be changed. This ISO sensitivity is a photographic film standard established by ISO and represents how much light the photographic film can record. However, generally ISO sensitivity is also used when expressing the sensitivity of the image sensor 30. In this case, the ISO sensitivity is a value representing the ability of the image sensor 30 to capture light. Increasing the gain improves the ISO sensitivity. For example, when the gain is doubled, the electrical signal (pixel signal) is also doubled, and the brightness is appropriate even when the amount of incident light is half. However, when the gain is increased, noise included in the electric signal is also amplified, so that noise increases.

  The thinning-out rate is the ratio of the number of pixels that do not read out pixel signals with respect to the total number of pixels in a predetermined area. For example, when the thinning rate of a predetermined area is 0, it means that pixel signals are read from all pixels in the predetermined area. Further, when the thinning rate of the predetermined area is 0.5, it means that the pixel signal is read from half of the pixels in the predetermined area.

  Further, the number of added rows refers to the number of vertical pixels (number of rows) to be added when pixel signals of pixels adjacent in the vertical direction are added. Further, the number of added columns refers to the number of horizontal pixels (number of columns) to be added when pixel signals of pixels adjacent in the horizontal direction are added. Such addition processing is performed in the arithmetic circuit 415, for example. The arithmetic circuit 415 performs the process of adding the pixel signals of a predetermined number of pixels adjacent in the vertical direction or the horizontal direction, thereby obtaining the same effect as the process of reading out the pixel signals by thinning out at a predetermined thinning rate. In the addition process described above, the average value may be calculated by dividing the added value by the number of rows or columns added by the arithmetic circuit 415.

  The number of bits for digitization means the number of bits when the signal processing circuits 412, 422, and 432 convert an analog signal into a digital signal in A / D conversion. As the number of bits of the digital signal increases, brightness, color change, and the like are expressed in more detail.

  In the first embodiment, as an example, the drive unit 32 in FIG. 2 controls the frame rate, the gain, and the thinning rate for each block. In addition, the drive unit 32 sets a block in the pixel region 113 </ b> A of the image sensor 30. The system control unit 24 instructs the drive unit 32 on the block position, shape, range, and the like.

  Returning to FIG. 1, the management device 50 includes a terminal such as a PC (Personal Computer), and collects and displays images captured by the monitoring camera 10 via the network 60. In addition, when receiving an instruction regarding the operation or setting of the monitoring camera 10 from the user (administrator), the management device 50 transmits the instruction to the monitoring camera 10 via the network 60.

  Next, processing of the monitoring camera 10 according to the first embodiment will be described in detail based on FIGS. 8 and 9 are flowcharts showing the processing of the surveillance camera 10 according to the first embodiment. 8 and 9 is started when the monitoring camera 10 is turned on and communication with the management apparatus 50 is established.

  In the process of FIG. 8, in step S10, the system control unit 24 sets common imaging conditions (for example, a frame rate, a gain, and a thinning rate) for all the plurality of blocks obtained by dividing the pixel region 113A of the imaging device 30. To do.

  Next, in step S12, the system control unit 24 starts imaging using the imaging element 30 in which imaging conditions common to all blocks are set. In step S12, the system control unit 24 instructs the image processing unit 16 to execute a moving body detection process using images captured in all blocks. In this case, the image processing unit 16 detects the moving subject by, for example, comparing the captured image with the image captured immediately before the captured image. Further, the system control unit 24 transmits imaging data to the management device 50 via the communication unit 26 in step S12. Since the management apparatus 50 displays the received imaging data on a display or the like, the administrator can view the image captured by the monitoring camera 10.

  Next, in step S14, the system control unit 24 waits until it is notified from the image processing unit 16 that a moving subject has been detected in any of the blocks. That is, until the moving subject is detected, the system control unit 24 continues imaging under the imaging conditions set in step S10. When the image processing unit 16 notifies that the moving subject has been detected, the system control unit 24 proceeds to step S16.

  In step S16, the system control unit 24 sets a variable block and its imaging condition. For example, as illustrated in FIG. 10, the system control unit 24 sets a range including a moving subject (a person in FIG. 10) in the fluctuation block 70. In FIG. 10 and the like, the size of the unit group 131 (the size of one square) is greatly expressed for convenience of illustration. In addition, the system control unit 24 sets the imaging conditions (for example, frame rate, gain, thinning rate) of the variable block 70 to conditions suitable for imaging the moving subject. For example, the system control unit 24 increases the gain when the moving subject is backlit and dark, increases the frame rate when the moving subject has a high moving speed, and receives an enlarged display request for the moving subject. Decrease the thinning rate. Further, the system control unit 24 maintains the imaging conditions set in step S10 for the imaging conditions of blocks other than the variable block 70. When the frame rate of the variable block 70 is changed (for example, when it is increased), the frame rate of the variable block 70 is set to a multiple of the frame rate of other blocks.

  Next, in step S18, the system control unit 24 instructs the recording unit 22 to start recording image data. For example, the system control unit 24 issues an instruction to the first recording unit 22A, starts recording image data from the first image processing unit 16A, issues an instruction to the second recording unit 22B, and performs second image processing. Recording of image data from the unit 16B is started. The recording of the image data from the first image processing unit 16A may be started immediately after step S12, but in the present embodiment, the recording is started after the moving subject is detected. Thereby, only the image in which the moving subject is imaged can be recorded.

  Next, in step S20, the system control unit 24 causes the variable block 70 to follow the moving subject. That is, the system control unit 24 adjusts the pixels included in the variation block 70 (unit group 131) and the pixels included in blocks other than the variation block 70 in accordance with the movement of the moving subject in the image obtained from the image processing unit 16. (Unit group 131) is different from time to time. Here, the variable block 70 follows the moving subject, and the variable block 70 is imaged under imaging conditions suitable for the moving subject, so that the state of the moving subject can be imaged and recorded with appropriate image quality. It becomes. Accordingly, it is possible to easily monitor the moving subject by the administrator who uses the management device 50.

  Next, in step S22, the system control unit 24 determines whether there are a plurality of moving subjects and the moving subjects have approached each other. For example, the system control unit 24 may cause the moving subjects to approach each other when there is an overlap between the moving blocks 70 including the moving subjects, or when the moving blocks 70 are not overlapped but are closer than a predetermined interval. Judge that The reason why it is determined whether or not the moving subjects have approached each other is that the moving subjects may collide as shown in FIG. 11 when the moving subjects approach each other.

  When the moving subjects are close to each other, the determination in step S22 is affirmed, and the process proceeds to step S24 in FIG. In step S <b> 24, the system control unit 24 resets the imaging condition of the variable block 70. For example, the system control unit 24 increases the gain of the variable block 70 larger than the value set in step S16, makes the frame rate of the variable block 70 higher than the value set in step S16, or thins the variable block 70. The rate is made smaller than the value set in step S16. As a result, the moving subject can be imaged and recorded with high image quality, and even when the moving subjects collide with each other, the analysis can be easily performed.

  On the other hand, when there are a plurality of moving subjects and the moving subjects are not close to each other, the determination in step S22 is denied and the process proceeds to step S30 in FIG. In step S30, the system control unit 24 determines whether the moving subject is no longer in the image (in the object scene). If the moving subject continues to exist in the imaging range, the determination in step S30 is denied and the process returns to step S22.

  After step S24, the process proceeds to step S26, and the system control unit 24 waits until the moving subjects are separated from each other. For example, the system control unit 24 waits until the overlapping of the variable blocks 70 each including the moving subject is eliminated or the variable blocks 70 are separated from each other by a predetermined interval. Therefore, until the moving subjects are separated from each other, the system control unit 24 performs imaging under the imaging condition set in step S24 for the variable block 70, and the imaging set in step S10 for blocks other than the variable block 70. Perform imaging under conditions. When the moving subjects are separated from each other, the process proceeds to step S28, and the system control unit 24 returns the imaging condition of the variable block 70 reset in step S24 to the imaging condition set in step S16.

  Next, in step S30, the system control unit 24 determines whether or not the moving subject is no longer in the image (in the object scene). If the moving subject continues to exist in the imaging range, the determination in step S30 is denied and the process returns to step S22.

  On the other hand, if the moving subject is no longer in the imaging range, the determination in step S30 is affirmed and the process proceeds to step S32. In step S32, the system control unit 24 determines whether or not the process is finished. Note that the system control unit 24 determines whether or not the process is to end based on whether or not the administrator inputs an end instruction from the management device 50 or the operation unit 20. If the determination here is negative, that is, if it is not the end, the process proceeds to step S34, the system control unit 24 returns the imaging conditions of all blocks to the state set in step S10, and returns to step S14. . Thereafter, the processes and determinations in steps S14 to S34 are repeated until the determination in step S32 is affirmed.

  As described above in detail, according to the first embodiment, the imaging unit 14 has a plurality of blocks each having at least one pixel, and imaging conditions can be set for each block. The system control unit 24 sets the variation block 70 based on the image captured by the imaging unit 14, and changes the imaging condition of the variation block 70 when the other moving subject is imaged by the variation block 70 (step S24). As a result, it is possible to image the moving subject under imaging conditions suitable for each occasion, and it is possible to capture the state of the moving subject with an appropriate image quality according to the situation. For example, an event that occurs between a plurality of moving subjects (for example, a collision between moving subjects) can be imaged under appropriate imaging conditions, and analysis of the event can be facilitated. Further, since the imaging condition of the variable block 70 including the moving subject is changed (for example, changed to a high gain, a high frame rate, a low thinning rate, etc.) and the imaging conditions of the other blocks are not changed, the data amount increases or the surveillance camera 10 Temperature rise can be suppressed. By suppressing the increase in the data amount in this way, it is possible to reduce the load related to the data amount of the communication line when image data is transmitted to the management apparatus via the network 60.

  In the first embodiment, when at least a part of the other moving subject is imaged by the variable block 70, the system control unit 24 changes the imaging condition of the variable block 70 from the first imaging condition to the second imaging condition. It has changed. Thereby, an event (for example, a collision between moving subjects) occurring between a plurality of moving subjects can be imaged under more appropriate imaging conditions.

  Further, as in the first embodiment, when the other moving subject detected by the image processing unit 16 in the variable block 70 is imaged, the system control unit 24 changes the imaging condition of the variable block 70. May be.

  Further, as in the first embodiment, the system control unit 24 sets the variable block 70 based on the position of one moving subject detected by the image processing unit 16 and the position of the other moving subject. Also good.

  Further, in the first embodiment, the system control unit 24 includes a block including one moving subject and the other moving subject when the distance between the position of one moving subject and the position of the other moving subject approaches. Is set in the fluctuation block 70. As a result, an event that occurs between a plurality of moving subjects can be captured more reliably.

  In the first embodiment, when the other moving subject is imaged in the variable block 70, the system control unit 24 changes the gain in the imaging of the variable block 70, so that the moving subject is imaged with appropriate brightness. be able to.

  In the first embodiment, when the other moving subject is imaged in the variable block 70, the system control unit 24 changes the frame rate in imaging of the variable block 70. Thereby, slow playback at an appropriate speed is possible.

  In the first embodiment, the first image processing unit 16A that performs image processing of all blocks (regions) captured by the imaging unit 14 and the variable block 70 (region) including the moving subject that the imaging unit 14 captures. A second image processing unit 16B that performs the image processing. Thereby, as shown in FIG. 12, the image of the fluctuation | variation block 70 can be cut out from all the blocks, and the image of the fluctuation | variation block 70 can be expanded and displayed in real time. In FIG. 12, the variable block 70 is set using a face recognition process in addition to the moving object detection process. In addition, the second image processing unit 16B may be constantly operating and the enlarged display may be performed constantly, or when the administrator touches the display of the management device 50, the second image processing unit 16B may be activated to perform an enlarged display.

  Further, as in the first embodiment, the system control unit 24 sets the imaging condition of the variable block 70 including the moving subject at the time when the moving subject enters the image (in the object scene) (first field). The time point may be different from the time point when the moving subjects approach (second time point). As a result, it is possible to image the moving subject under imaging conditions suitable for each occasion, and it is possible to capture the state of the moving subject with an appropriate image quality according to the situation.

  Further, as in the first embodiment, a plurality of variable blocks 70 including a moving subject exist in the image (in the field), and the system control unit 24 determines the position of the variable block 70 including a plurality of moving subjects. You may make it change imaging conditions according to a relationship. As a result, an event occurring between a plurality of moving subjects can be imaged under appropriate imaging conditions, and the event can be easily analyzed.

  In addition, as in the first embodiment, the system control unit 24 detects the time (first time) when the moving subject enters the image (in the object scene) and the time when the moving subjects approach (first time). 2), the gain in imaging of the variable block 70 including the moving subject may be different. For example, by increasing the gain in imaging when the moving subjects approach each other than when the moving subject enters the image, it is possible to brighten the imaging of the collision site between the moving subjects.

  In addition, as in the first embodiment, the system control unit 24 detects the time (first time) when the moving subject enters the image (in the object scene) and the time when the moving subjects approach (first time). 2), the frame rate in imaging of the variable block 70 including the moving subject may be different. For example, by increasing the frame rate at the time when moving subjects approach each other than when the moving subject has entered the image, it is possible to slow-play a moving image when the moving subjects collide more slowly. It becomes possible.

  In the first embodiment, the system control unit 24 has been described with respect to an example in which the gain, frame rate, and thinning rate in imaging of the variable block 70 are varied. However, other imaging conditions may be varied. Good. For example, the system control unit 24 controls control parameters for controlling the image sensor 30 (for example, charge accumulation time or number of accumulations, frame rate, gain) and control parameters for controlling signal readout from the image sensor 30 ( For example, the control parameters for processing signals from the image sensor 30 (for example, the number of added rows or added columns to which pixel signals are added, the number of digitization bits), or the like may be different.

<< Second Embodiment >>
Next, a second embodiment will be described in detail based on FIGS.

  The configuration of the surveillance camera system according to the second embodiment is the same as or equivalent to that of the surveillance camera system 500 according to the first embodiment of FIG. The configuration of the surveillance camera is the same as or equivalent to that of the surveillance camera according to the first embodiment shown in FIGS. The first image processing unit 16A of the image processing unit 16 performs image processing of signals from pixels included in all blocks, and the second image processing unit 16B performs image processing of signals from pixels included in the target block. Execute the process.

  Next, the process of the surveillance camera of the second embodiment will be described in detail based on FIGS. 13 and 14 show the processing of the monitoring camera 10 according to the second embodiment in a flowchart. Note that the processing of FIGS. 13 and 14 is performed when the monitoring camera 10 is turned on and managed. It starts when communication with the device 50 is established.

  In the process of FIG. 13, in step S40, the system control unit 24 sets common imaging conditions (for example, frame rate, gain, and thinning rate) for all the plurality of blocks obtained by dividing the pixel region 113A of the imaging device 30. To do.

  Next, in step S <b> 42, the system control unit 24 sets some blocks in the image as the target block 72 in accordance with an input from the administrator. For example, as shown in FIG. 15, when the turning angle of the passage is imaged within the imaging range of the monitoring camera 10, the turning angle range is set to the block of interest 72. This is because it is easy for moving subjects to collide at a corner.

  Next, in step S44, the system control unit 24 starts imaging using the imaging element 30 in which imaging conditions common to all blocks are set. In step S44, the system control unit 24 instructs the image processing unit 16 to execute moving object detection processing using images captured in all blocks. Further, the system control unit 24 transmits imaging data to the management apparatus 50 via the communication unit 26 in step S44.

  Next, in step S46, the system control unit 24 waits until it is notified from the image processing unit 16 that a moving subject has been detected in any of the blocks. That is, until the moving subject is detected, the system control unit 24 continues imaging under the imaging conditions set in step S40. When the image processing unit 16 notifies that the moving subject has been detected, the system control unit 24 proceeds to step S48.

  In step S48, the system control unit 24 instructs the recording unit 22 to start recording image data. For example, the system control unit 24 issues an instruction to the first recording unit 22A, starts recording image data from the first image processing unit 16A, issues an instruction to the second recording unit 22B, and performs second image processing. Recording of image data from the unit 16B is started. Note that the recording of the image data may be started immediately after step S44.

  Next, in step S <b> 50, the system control unit 24 determines whether the position of the moving subject in the image obtained from the image processing unit 16 has entered the target block 72. For example, the system control unit 24 determines whether or not the moving subject (person) that has entered the imaging range has entered the target block 72 as illustrated in FIG. 16B, as illustrated in FIG. To do. The determination as to whether or not the moving subject has entered the target block 72 may be made when it is determined that the entire moving subject has completely entered the target block 72 or has entered the target block 72. It may be determined that a part of has entered the target block 72.

  When the moving subject enters the attention block 72, the determination in step S50 is affirmed, and the process proceeds to step S52 in FIG. In step S52, the system control unit 24 sets the imaging condition of the block of interest 72. For example, the system control unit 24 makes the gain of the block of interest 72 larger than the value set in step S40, makes the frame rate of the block of interest 72 higher than the value set in step S40, The rate is made smaller than the value set in step S40. This makes it possible to capture and record the moving subject with high image quality in a situation where the moving subject enters the target block 72.

  On the other hand, if the moving subject is not in the target block 72, the determination in step S50 is negative and the process proceeds to step S58 in FIG. In step S58, the system control unit 24 determines whether the moving subject is no longer in the image (in the object scene). If the moving subject continues to exist in the imaging range, the determination in step S58 is negative and the process returns to step S50.

  After step S52, the process proceeds to step S54, and the system control unit 24 waits until the moving subject goes out of the block of interest 72. The determination as to whether or not the moving subject has left the attention block 72 may be made by determining that the movement subject has completely left the attention block 72 and that the movement subject has left the attention block 72. Alternatively, when a part of the moving subject has left the attention block 72, it may be determined that the movement subject has left the attention block 72. Therefore, until the moving subject leaves the target block 72, the system control unit 24 performs imaging under the imaging conditions set in step S52 for the target block 72, and step S40 for blocks other than the target block 72. Imaging is performed under the imaging conditions set in.

  When the moving subject leaves the target block 72, the process proceeds to step S56, and the system control unit 24 returns the imaging condition of the target block 72 set in step S52 to the imaging condition set in step S40.

  Next, in step S58, the system control unit 24 determines whether or not the moving subject is no longer in the image (in the object scene). If the moving subject continues to exist in the imaging range, the determination in step S58 is negative and the process returns to step S50.

  On the other hand, if the moving subject is no longer in the imaging range, the determination in step S58 is affirmed and the process proceeds to step S60. In step S60, the system control unit 24 determines whether the process is finished. When judgment here is denied, ie, when it is not completion | finish, it returns to step S46. Thereafter, the processes and determinations in steps S46 to S60 are repeated until the determination in step S60 is affirmed.

  As described above in detail, in the second embodiment, the system control unit 24 sets the attention block 72 based on the image captured by the imaging unit 14, and when the moving subject is imaged by the attention block 72, the attention block The imaging condition 72 is changed (step S52). As a result, the moving subject can be imaged under appropriate imaging conditions in a place where it is desired to monitor the moving subject while paying attention (for example, a place where the moving subject may be dangerous).

  In the second embodiment, the system control unit 24 changes the imaging condition of the target block 72 from the first imaging condition to the second imaging condition when at least a part of the moving subject is captured by the target block 72. ing. Thereby, an event (for example, a collision between moving subjects) occurring in the target block 72 can be imaged under a more appropriate imaging condition.

  Further, as in the second embodiment, when the moving subject detected by the image processing unit 16 is imaged by the attention block 72, the system control unit 24 may change the imaging condition of the attention block 72. Good.

  In the second embodiment, the case where the turning corner of the passage is set to the attention block 72 is shown as an example. However, moving objects such as entrances and exits of buildings such as buildings, factories, and houses and bank ATMs are used. You may set to the attention block 72 the place which wants to see paying attention.

<< Third Embodiment >>
Next, the third embodiment will be described in detail with reference to FIGS. 17 to 21B. The third embodiment is an example in the case where the moving subject is not a person but an article conveyed by a conveyance system provided in a factory.

  FIG. 17 is a diagram illustrating a factory 90 including a transport system 80 according to the third embodiment. As shown in FIG. 17, the transport system 80 is provided in a factory 90. The conveyance system 80 includes a conveyance device (for example, a belt conveyor) 84 that conveys an article (for example, a semi-finished product) 82, a monitoring camera 10 that images the article 82 that is conveyed by the conveyance device 84, and an image captured by the monitoring camera 10. And a display device 86 for displaying. The configuration of the monitoring camera 10 is the same as or equivalent to that of the monitoring camera according to the first embodiment shown in FIGS. The display device 86 is, for example, an LCD (Liquid Crystal Display). The worker performs an operation at the work place 88 on the transfer device 84 with respect to the article 82 transferred by the transfer device 84. The finished article 82 is transported from the work place 88 to perform the next process.

  A plurality of transfer systems 80 may be provided in the factory 90, and the monitoring camera 10 included in each transfer system 80 may be connected to the management apparatus 50 via a network or the like.

  Next, processing of the monitoring camera provided in the transport system 80 of the third embodiment will be described in detail based on FIGS. 18 to 21B. 18 and 19 are flowcharts showing the processing of the monitoring camera 10 provided in the transport system 80 according to the third embodiment. 18 and 19 starts when the monitoring camera 10 is turned on.

  In the process of FIG. 18, in step S <b> 70, the system control unit 24 sets some blocks in the image as the moving object detection block 74 in accordance with an input from the administrator. For example, as shown in FIG. 20A, a range including the upstream portion of the work place 88 on the transport device 84 is set in the moving object detection block 74.

  Next, in step S72, the system control unit 24 sets common imaging conditions (for example, a frame rate, a gain, and a thinning rate) for all of a plurality of blocks obtained by dividing the pixel region 113A of the imaging device 30.

  Next, in step S <b> 74, the system control unit 24 sets some blocks in the image as the target block 72 in accordance with an input from the administrator. For example, as illustrated in FIG. 20B, a range including the work place 88 on the transport device 84 is set as the target block 72. This is because the work is performed on the article 82 at the work place 88, so that the work is monitored.

  Next, in step S76, the system control unit 24 starts imaging using the imaging element 30 in which imaging conditions common to all blocks are set. In step S76, the system control unit 24 instructs the image processing unit 16 to execute a moving object detection process using an image captured by the moving object detection block 74. In step S76, the system control unit 24 transmits imaging data to the display device 86 via the communication unit 26, and causes the display device 86 to display a captured image.

  Next, in step S78, the system control unit 24 waits until the image processing unit 16 notifies that the moving subject (article 82) has been detected by the moving object detection block 74. That is, until the article 82 is detected, the system control unit 24 continues imaging under the imaging conditions set in step S72. When the image processing unit 16 is notified that the article 82 has been detected, the system control unit 24 proceeds to step S80.

  In step S80, the system control unit 24 sets a variable block and its imaging condition. For example, as illustrated in FIG. 21A, the system control unit 24 sets a range in which the article 82 is included in the variable block 70. Then, the system control unit 24 sets the imaging condition (for example, frame rate, gain, thinning rate) of the variable block 70 to a condition suitable for imaging the article 82. For example, the system control unit 24 increases the gain when the article 82 is backlit and dark, increases the frame rate when the moving speed of the article 82 is high, and receives an enlarged display request for the article 82. Reduce the thinning rate. Further, the system control unit 24 maintains the imaging conditions set in step S72 for the imaging conditions of blocks other than the variable block 70.

  Next, in step S82, the system control unit 24 instructs the recording unit 22 to start recording image data. For example, the system control unit 24 issues an instruction to the first recording unit 22A, starts recording image data from the first image processing unit 16A, issues an instruction to the second recording unit 22B, and performs second image processing. Recording of image data from the unit 16B is started. Note that the recording of the image data from the first image processing unit 16A may be started immediately after step S76.

  Next, in step S84, the system control unit 24 causes the variable block 70 to follow the article 82. That is, the system control unit 24 adjusts the pixels (unit group 131) included in the variation block 70 and the pixels included in blocks other than the variation block 70 in accordance with the movement of the article 82 in the image obtained from the image processing unit 16. (Unit group 131) is different from time to time.

  Next, in step S <b> 86 of FIG. 19, the system control unit 24 waits until the article 82 enters the target block 72. For example, the system control unit 24 waits until the article 82 conveyed by the conveyance device 84 enters the target block 72 including the work place 88 as shown in FIG. Whether or not the article 82 has entered the attention block 72 may be determined by determining that the article 82 has entered the attention block 72 when a part of the fluctuation block 70 overlaps the attention block 72. It may be determined that the article 82 has entered the attention block 72 when all 70 overlap the attention block 72. Therefore, until the article 82 enters the block of interest 72, the system control unit 24 performs imaging under the imaging condition set in step S80 for the variable block 70, and sets the block other than the variable block 70 in step S72. Imaging is performed under the specified imaging conditions. When the article 82 enters the target block 72, the system control unit 24 proceeds to step S88.

  In step S88, the system control unit 24 resets the imaging condition of the variable block 70. For example, the system control unit 24 increases the gain of the variable block 70 larger than the value set in step S80, makes the frame rate of the variable block 70 higher than the value set in step S80, or thins the variable block 70. The rate is made smaller than the value set in step S80. This makes it possible to capture and record the state of the article 82 at the work place 88 that may cause a defect in the article 82 with high image quality.

  After step S88, the process proceeds to step S90, and the system control unit 24 waits until the article 82 leaves the target block 72. Note that whether or not the article 82 has left the target block 72 is determined by determining that the article 82 has left the target block 72 when a part of the variable block 70 does not overlap the target block 72. Alternatively, it may be determined that the article 82 has left the target block 72 when all of the variable blocks 70 do not overlap the target block 72. Therefore, until the article 82 leaves the target block 72, the system control unit 24 performs imaging under the imaging condition set in step S88 for the variable block 70, and for step S72 for blocks other than the variable block 70. Imaging is performed under the imaging conditions set in.

  When the article 82 leaves the target block 72, the process proceeds to step S92, and the system control unit 24 resets the imaging condition of the variable block 70. In this case, the imaging condition of the variable block 70 may be returned to the imaging condition set in step S80, or may be changed to an imaging condition different from that in step S80.

  Next, in step S94, the system control unit 24 stands by until the article 82 disappears from the image (in the object scene). That is, until the article 82 disappears from the image, the system control unit 24 performs imaging under the imaging condition set in step S92 for the variable block 70, and sets the block other than the variable block 70 in step S72. Imaging is performed under the specified imaging conditions. After the article 82 disappears from the image, the system control unit 24 proceeds to step S96.

  In step S96, the system control unit 24 determines whether or not the process is finished. When judgment here is denied, ie, when it is not completion | finish, it returns to step S78. Thereafter, the processes and determinations in steps S78 to S96 are repeated until the determination in step S96 is affirmed.

  As described above in detail, in the third embodiment, the moving subject is the article 82 that is conveyed by the conveyance device 84, and the system control unit 24 includes the variable block 70 including the article 82 in the target block 72. Then, the imaging condition of the variable block 70 including the article 82 is changed (step S88). For example, in the third embodiment, the system control unit 24 sets the imaging condition of the variable block 70 including the article 82 at the time point when the article 82 is outside the work place 88 (first time point) and the time point when it is inside the work place 88. (Second time point). Even in this case, the state of the article 82 can be imaged with an appropriate image quality according to the situation at that time. For example, the cause analysis when a defect occurs in the article 82 can be performed using an appropriate image (for example, an image with a high resolution, a high frame rate, or the like).

  Further, in the third embodiment, the transport system 80 includes the display device 86 that displays an image captured by the monitoring camera 10, so that an image captured of the article 82 is displayed near the transport device 84 by an operator, its upper manager, and the like. Can be seen. For this reason, the cause analysis of the defect that has occurred in the article 82 can be performed at the work site.

  In the third embodiment, when the variable block 70 including the article 82 enters the target block 72, the imaging condition of the variable block 70 is not changed, but the article is the same as in the first embodiment. When the block including the worker's tool approaches the variable block 70 including 82, the imaging condition of the variable block 70 may be changed.

  In the third embodiment, the number of target blocks 72 is not limited to one, but may be plural.

  In the first to third embodiments, the system control unit 24 has different imaging conditions for blocks including the moving subject at the first time point and the second time point when the moving subject speed is different. The imaging unit 14 may be controlled according to the state of the moving subject, such as controlling the imaging unit 14 as described above.

  In the first to third embodiments, the imaging element can change the imaging condition for each imaging area. However, the imaging element may be an imaging element in which all imaging areas can only have the same imaging condition. In this case, when changing the imaging conditions, the imaging conditions of all the imaging areas are changed in the same way.

  In the first and second embodiments, the moving subject is a person, and in the third embodiment, the moving subject is an article (semi-finished product). However, the present invention is not limited to this. . The moving subject may be other cases such as animals other than humans, cars, and objects that may be imaged during a disaster (water, fire, etc.).

Also good. When the monitoring camera 10 is disposed in the vehicle, an oncoming vehicle or a pedestrian that appears in front of the vehicle may be imaged as a moving subject. Moreover, when the monitoring camera 10 is arrange | positioned in a stadium, you may image the player in competition as a moving subject. Further, the management device 50 may be integrated with the monitoring camera 10.

It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program.
