By mounting the main body 2 on the lower surface side of the fixed mounting base 1, the installation of the image sensor device is completed.

  Here, the circuit configuration of the image sensor device of the present embodiment will be briefly described with reference to FIG.

  In the present embodiment, silhouette matching is performed from a signal processing circuit unit 100 including a microcomputer mounted on a signal processing circuit board 43, a light emitting diode LED group, an imaging camera unit 101, and a video signal captured by the imaging camera unit 101. An image processing circuit unit 102 composed of an ASIC (Application Specific Integrated Circuit) that performs image processing, and a video output unit for outputting a video signal obtained, for example, by NTSC / EIA to an image captured by the imaging camera unit 101 103, a human body detection sensor unit 104 configured by the human body detection sensor block B, a contact unit 105 including a relay that is controlled by the signal processing circuit unit 100 and outputs a no-voltage contact signal as an alarm output, and an external power source The power supply circuit unit 106 that receives the supply, converts the voltage into a voltage corresponding to each unit, and supplies the converted voltage. .

  Next, the signal processing operation of the signal processing circuit unit 100 will be briefly described with reference to the flowchart shown in FIG.

  First, the signal processing circuit unit 100 is configured to input an image processing result from the image processing circuit unit 102 by outputting a processing start signal to the image processing circuit unit 102 (step S1). Here, the image processing circuit unit 102 composed of the ASIC extracts the contour image of the moving object excluding the background from the video of the detection area captured by the imaging camera unit 101, and the position on the image and the position of the moving contour image on the image. A function of performing image processing for obtaining a size (rectangular frame) and edge direction distribution is provided, and the image processing result is output to the signal processing circuit unit 100.

The signal processing circuit unit 100 uses the input size data of the image processing result, and compares the size data with a preset size threshold in step S2 to determine the size of the moving object. If it is, it is determined that the moving object is not a person but a small animal or the like, and the process returns to step S1. The determination process here is a process for determining whether or not the distribution is biased from a predetermined value. If it is determined that there is no bias, the process returns to step S1, and if it is determined that there is a bias, the movement of the moving object is determined. The continuity is determined by tracking position data (step S4) . If there is no continuity of movement, the process returns to step S1, and if there is continuity of movement, the area is determined in step S5. This detection area is an area excluding a preset mask (mask outside the area), and if a moving object exists outside the detection area, the process returns to step S1, and if it is within the detection area, In the next step , a composite determination is made using the output of the human body detection signal of the human body detection sensor unit 104. That is, when the human body detection signal is not output from the human body detection sensor unit 104, the process returns to step S1, and when the human body detection signal is output, the contact unit 105 is controlled in step S6 to generate an alarm output. It has become.

The image processing circuit unit 102 has a function of obtaining an average luminance from a luminance value from an image signal from the imaging camera unit 101, and the signal processing circuit unit 100 performs a process of reading average luminance data before inputting an image processing result, and continuously. Then, when the average luminance value is smaller than the lower limit value of the luminance, when the predetermined number of times is continuously exceeded, the light emitting diode LED group is controlled to emit light before outputting the next processing start signal determined to have exceeded. It has become.

By the way, after the installation on the ceiling is finished as described above, when it is necessary to adjust the depression angle of the imaging camera unit 101 in order to obtain a detection area suitable for the ceiling height, the translucent cover 3 is removed, By holding and rotating the grip portion of the movable cover 46 of the camera block A, the depression angle of the imaging camera unit 101 can be adjusted. In this embodiment, if the translucent cover 3 is removed before the power is turned on, the signal processing circuit unit 100 does not perform the alarm output process by the signal of the tamper switch SW3 even if the power is turned on thereafter.

  Further, when it is desired to set a detection target area, that is, a mask area MA within the detection area, the setting is made using the movement switch SW1 and the setting switch SW2. In this case, as shown in FIG. 8, the jack 72 and the video input terminal of the monitor TV 75 are connected via a coaxial cable 76 with a plug, and the captured video of the imaging camera unit 101 is monitored by the monitor TV 75. By pressing both switches SW1 and SW2 for a predetermined operation procedure or operation time in the monitored state, the signal processing circuit unit 100 sets the operation mode to the mask setting mode, and the image processing circuit unit 102 and the signal As shown in FIG. 9, a setting frame MS indicated by a grid and a thick line in which the captured image is divided into, for example, 8 × 10 blocks by the processing operation of the processing circuit unit 100 is displayed as an overlay on the captured image. . In this state, the operator operates the movement switch SW1 while viewing the monitor screen to move the setting frame MS on the screen, and operates the setting switch SW2 when the setting frame MS reaches a desired position. It is possible to set the mask area where the position of the frame is not detected. This set mask area MA is painted black on the screen, indicating that the mask area MA is set. When setting a plurality of mask areas MA, the movement and setting operations may be repeated. Of course, the entire area can be set as a detection area according to the operation procedure and operation time of the switches SW1 and SW2, and these setting processes are performed by the signal processing circuit unit 100. It should be noted that when a certain time has elapsed after the setting is completed, the signal processing circuit unit 100 automatically returns it.

  When the adjustment of the rotation angle of the camera block A and the setting of the mask area are completed as described above, the installation adjustment is completed when the permeable cover 3 is attached to the body 28.

In this embodiment, there is a feature that it is not necessary to prepare a special mask operating device. However, in order to perform the mask operation remotely, an external connection unit for taking in a remote operation signal is provided in the signal processing circuit unit 100. It may be possible to select an operation method suitable for the installation site by enabling mask operation on the main body 2 side or remotely.
