FIG. 4 is a time chart showing the function for setting the reaction time, FIG. 5 is a time chart showing the automatic switching function of the recording setting by the sensor reaction, and FIG. 6 is a function using the photochromic lens. FIG.

  First, prior to the description of the embodiments, an outline of a camera system necessary for implementing the present invention will be described. As a camera, a CCD, a CMOS camera, or the like is used, and all kinds of cameras used for monitoring can be used. In addition, a living body, particularly a human body sensing sensor is required. When a captured image is viewed on a moving image or still image conversion unit, a composition unit thereof, and a monitor or a PC, a transmission path, a data separation unit, and a composite unit are required. Also, a known compression method can be used for the image.

  Referring to FIG. 1, the invention described in claim 1 will be described. The image pickup by the camera and the recording of the image are started by the detection of the human body sensor, but a switch for turning off the input is provided in the sensor, and this switch is turned on. Therefore, the detection function of the sensor is stopped or the function of the camera or memory for data recording is stopped for a certain time. This eliminates the waste of opening the door monitored by the camera and recording the appearance of the housekeeper. Further, the switch is of a timer type and is restored after the lapse of the predetermined time to execute a normal recording / recording operation.

  Further, the invention according to claim 2 will be described with reference to FIG. 2. When the recording time is set to 5 seconds and the number of times is set to 2 corresponding to the response of the sensor, the imaging for 5 seconds corresponds to the detection of the sensor. Recording is performed but the sensor response time is long. For example, if there is a person who stays at the front of the door for a long time, the entire response is not recorded. Only recording. As a result, it is possible to omit imaging and recording that seem to be useless, and to suppress battery consumption.

  Furthermore, FIG. 3 explains the invention described in claim 3 and claim 4. According to the present invention, moving images and still images captured by a camera are recorded in a data recording device (memory), and the data is transferred to an external device having a function of sending an e-mail via a LAN. E-mail is sent from the device to the specified e-mail address, often the e-mail address of the mobile phone. With this function, it is now possible to check imaging data that could not be confirmed before returning home, even when you are away from home, and promptly contact important persons or report suspicious individuals. Can be done. In this case, the data to be sent by e-mail is assumed to be a still image, but it can also be a moving image, and the external device is not limited to the LAN function as long as e-mail can be sent via the network. Good.

  The invention according to claim 5 will be described with reference to FIG. According to the present invention, when the reaction time of the sensor is not longer than a predetermined time, the imaging, the recording and the storage are not performed. In this embodiment, the case where 3 seconds is set as the fixed time is shown. In this configuration, as shown in FIG. 4, recording is not performed when the sensor response is within 1 second or 2 seconds within 3 seconds, but recording is performed when the response is 5 seconds or 10 seconds. As a result, people who have just passed through will not be able to record, thus reducing battery consumption and saving the capacity of the recording medium.

  Further, the invention according to claim 6 will be described with reference to FIG. According to the present invention, when the recording time is set to be intermittent at regular time intervals, the recording time interval can be automatically switched when there is a response from the sensor. This switching particularly shortens the time interval. For example, only when there is a visitor or the like, the recording time interval can be narrowed and imaging and recording can be performed.

  The invention described in claims 7 and 8 will be described with reference to FIG. According to this invention, the lens, which is an element necessary for carrying out the present invention, is made of photochromic glass. This photochromic lens contains a silver halide crystal, and has a characteristic that it is colored by irradiation with light and returns to its original state when the irradiation is stopped. Also, the coloring concentration, coloring and fading speed are high, and there is no repeated fatigue. Many image elements used in this system are deteriorated by irradiation with light rays and ultraviolet rays. By limiting the amount of light, the image elements can be adversely affected without any lens replacement work. In addition, a clear image can be secured even in a place or time zone where the amount of light is small.
