Next, the operation of the security photographing storage device according to the present invention will be described with reference to the flowcharts of FIGS.
As shown in FIG. 4, when the power switch 70 is turned on, a “standby” state is set. When the “visitor stands in front of the door”, the motion sensor 20 is activated to enter the “visitor sensor operation” state. As a result, a signal is sent from the human sensor 20 to the control unit 55. The control unit 55 activates the CCD camera 30 and starts “capturing a visitor's image”.
Next, the control unit 55 determines whether or not the “answering mode” is set, and if the answering mode is set, “stores with an auto shutter”. That is, a still image is taken by the CCD camera 30 and the information is stored in the memories 51 and 52.
Then, after a predetermined time, the presence of a visitor in front of the door is confirmed again. When the visitor does not leave in front of the door, the signal of the human sensor 20 is “visitor sensor operating state”. At this time, “save with auto shutter” is performed again. A still image is taken by the CCD camera 30 and the digital information is stored in the memories 51 and 52. The length of the predetermined time may be set as appropriate. In addition, the time may be appropriately changed according to installation conditions.
In a state where the human sensor 20 senses a visitor, the above operation is repeated several times.
Next, again, the control unit 55 confirms “visitor sensor operation”. When the visitor stays and the human sensor 20 detects the visitor, the above operation is repeated again after “fetching the visitor image” after a predetermined time. If the visitor is away, return to the “standby” state. The length of the predetermined time may be set as appropriate. In addition, the time may be appropriately changed according to installation conditions.

Further, when the “absence mode” is determined and the home mode is selected instead of the absence mode, the captured image is “projected on the liquid crystal monitor”. The image information captured by the CCD camera 30 is sent to the monitor unit 40 via the control unit 55.
Then, “save manually if necessary”. That is, by pressing the manual shutter button 63, a still image is taken by the CCD camera 30, and the information is stored in the memories 51 and 52.
Next, the control unit 55 confirms “visitor sensor operation”. If the visitor stays and is detected by the motion sensor 20, the operation described above is repeated again after a predetermined time, starting from “getting a visitor image”. If the visitor is away, return to the “standby” state.

Next, a procedure for confirming a still image recorded by the user of the security photographing storage device will be described with reference to FIG.
When the user “gets home” and presses the home button 61 of the operation unit 60, the absence mode is canceled. As a result, the “confirmation of captured image” can be performed. Use the operation buttons to “confirm on the LCD monitor”.
By depressing the feed button 66 and the return button 65, “next image confirmation” can be sequentially performed. By pressing down the save button (the manual shutter button 63 or the like may be shared), “Save to external memory (SD card)” can be set. Further, the recorded still image can be erased by depressing the erase button 64.
When there are a plurality of visitors, the above operation is “repeated by the number of visitors” to confirm, save or delete the image.
If the power is kept on, the state returns to the “standby” state, and if the power is turned off, the process ends.
