The camera unit 10 is configured to capture an image of a subject. The transfer unit 20 is used to capture the camera unit 10.撷The image is transferred to the face recognition unit 40 and the display unit 30. The face recognition unit 40 identifies a person's face from the captured image, and generates a face contour information corresponding to each face, the memory unit The image captured by the camera unit 10 and the face rim information generated by the face recognition unit 40 are memorized. The search unit 60 can search for the face of the previously memorized face in the memory unit 50 for the target person. The display unit 30 can display the result of the search unit search and display the captured image. [0020] The image capturing unit 10 can respectively include multiple camera devices 19 respectively disposed in different monitoring areas. The camera unit 19 includes a lens unit 11 and a sensing unit 12. The lens unit 11 is a lens module including at least one optical lens. The lens unit 11 is configured to collect optical signals and transmit the optical signals to The sensing unit 12 is a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semi Conductor). The sensing unit 12 is configured to convert the optical signal condensed by the lens unit 11 into an image signal. [0021] In the embodiment, the transfer unit 20 is an optical fiber for imaging 1013112393-0. Single Number A〇101 Page 5 of 15 Page 1375926 The image signal captured by the replacement page unit 10 is transmitted to the face recognition unit 40 and the display unit 30, respectively. [0022] The display unit 30 can be A plurality of displays are included, and an image of the object captured by the image capturing unit 10 transmitted by the transfer unit 20 is immediately observed when the image is taken by the image capturing unit 10. In the actual application, when the camera unit 10 has only one camera device 19 and the display unit 30 has only one display, the image signal captured by the camera unit 10 can also be directly transmitted to the display unit 30 without being transferred by the transfer unit 20 Transfer. [0024] The face recognition unit 40 identifies a person's face in the image captured by the image capturing unit 10, and generates a face contour information corresponding to each face. [0025] The memory unit 50 is configured to memorize the image captured by the at least one camera unit and the face contour information generated by the face recognition unit 40. The search unit 60 can search for the target person in the memory unit 40 whether it is the same as the face profile information previously memorized. In a specific use, if a target person needs to be queried, the camera unit 10 images the target person, and at this time, the face recognition unit 40 simultaneously generates the face profile information of the person, and the search unit 60 points the person of the target person. The face contour information is compared with all face contour information stored by the memory unit 50. Since different people have different face contour information, if the search unit 60 searches for the same face contour information from the memory unit 50, the monitoring video of the target person is displayed by the display unit 30. To achieve the purpose of quickly querying whether the target person has appeared from the image stored in the memory unit 50, the number 0912535# single number A〇101 page 6/total 15 page 1013112393-0 1375926 101.
