  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing the configuration of the surveillance camera system according to Embodiment 1 of the present invention. In this system, for example, four nurses are targeted, and sensors 1a, 1b, 1c, and 1d worn by the respective nurses and a control device 2 that receives the data are provided. In addition, cameras 4 a, 4 b, 4 c, and 4 d for photographing each care recipient, a video processing device 3, a recording device 5, and a monitor 6 are provided. The operation of the surveillance camera system according to Embodiment 1 configured as described above will be described below with reference to FIG. 1 as appropriate.

  In this surveillance camera system, for example, inpatients who are nurses wear sensors 1a, 1b, 1c, and 1d, sense biological information such as pulse and body temperature, and transmit the information to the control device 2. . The control device 2 receives biological information from each sensor, compares it with a numerical value in a normal range registered in advance, and sequentially determines whether each patient has an abnormality.

  In addition, cameras 4a, 4b, 4c, and 4d are installed for each care recipient, and the captured video signals are connected to the video processing device 3, and the video signals are supplied to the recording device 5 and the monitor 6. .

  In normal times, that is, when the control device 2 determines normal, for example, four camera images are projected on a four-divided screen. Alternatively, the video may not be supplied to the monitor 6 or the videos of the plurality of cameras 4a to 4d may be displayed on the monitor 6 in a time-division manner at a predetermined time interval.

  Here, a case where a sudden change occurs in a certain patient A will be described below. At this time, biological information such as pulse and body temperature is sensed by the sensor 1a worn by the patient A. If the numerical value exceeds the set range, the patient A has an abnormality. Judge that it occurred. Then, the control device 2 generates a control signal for notifying the care receiver A that an abnormality has occurred to the video processing device 3. In response to this control signal, the video processing device 3 selects the video signal of the camera 4 a that is photographing the care recipient A in which an abnormality has occurred and outputs it to the monitor 6.

  In this case, you may raise the sensitivity of the camera 4a which image | photographs the patient to whom the sensor 1a determined to be the abnormality is mounted | worn.

  A recording device 5 is connected to the video processing device 3, which is composed of, for example, a hard disk or the like. It shall be recorded. For example, the video signal of the last 5 minutes is always recorded for each camera, and the signal before 5 minutes is deleted. However, when an abnormality occurs in the care recipient, the image of the care recipient recorded at that time is not erased and protected, and the subsequent signals are also continuously recorded. When the control device 2 determines that there is an abnormality, the video signal of the recording device 5 can be output to the monitor 6 or the video before the abnormality occurs can be reproduced and viewed according to the nurse's request.

  In the above description, four nurses are used. However, the number of nurses is not limited to four, and the number of monitors is not limited to one.

  By the way, there is a case where the act of constant monitoring by the camera is objectionable in terms of privacy for the caregiver, so the process of displaying the caregiver only when an abnormality has occurred and the monitor image is normally set to no screen. You may go.

  In addition, in the monitoring of inpatients by nurses in hospitals and the like, there is naturally monitoring at night when the lights are turned off, but naturally the patient is sleeping and cannot be brightened. Therefore, at night, the camera is set to the high sensitivity mode for shooting.

  As a method for switching to the high sensitivity mode, simply increasing the signal gain increases the noise. For example, there is a method of increasing the signal charge by taking a longer exposure time than usual. There is also a method of increasing signal charges by adding pixels to each other in an image sensor such as a CCD (Charge Coupled Device).

  The surveillance camera system according to the present invention is characterized in that a patient is monitored, and when an abnormality occurs, the image of the patient is automatically displayed on the monitor and the nurse is warned. This is useful as a surveillance camera system for monitoring a patient.

The block diagram which shows the structure of the surveillance camera system in Embodiment 1 of this invention.
