  In order to make those skilled in the art understand the purpose, characteristics, and effects of the present invention, the following specific examples will be given and the present invention will be described in detail with reference to the drawings.

  The present invention provides a display device that can automatically face the face. FIG. 1 is a functional block diagram of a first embodiment of an automatic rotation display device having a head image identification function of the present invention. With reference to FIG. 1, the display device 10 includes a screen 11, an image acquisition device 12, a control module 13, and a drive device 14. The screen 11 may be any one of a liquid crystal screen, a plasma screen, a projection screen, or a light emitting diode screen. The image acquisition device 12 is a camera and is positioned directly above the screen 11 (see FIG. 2). The control module 13 is a microprocessor and installs face identification software in the control module 13. The control module 13 and the image acquisition device 12 can be electrically connected via a RS232, USB (Universal Serial Bus) wired system, or via a Bluetooth or infrared wireless system. The control module 13 is further electrically connected to the drive device 14. The display device 10 may further include a storage module, and the storage module stores information to be displayed on the screen 11 of the display device 10.

  2 is an explanatory diagram in which the driving device and the screen are directly connected, FIG. 3 is an explanatory diagram in which the driving device and the screen are indirectly connected, and with reference to FIG. 2 and FIG. It is a motor, and the motor rotation shaft of the motor and the screen 11 are directly connected, or the motor is indirectly connected to the screen 11 via a gear.

  FIG. 4 is a control flow diagram of the control module. 1 to 4, first, in step S <b> 201, the control module 13 receives an image in front of the screen 11 acquired by the image acquisition device 12 and generates an image signal relative thereto. Subsequently, in step S202, the control module 13 receives the image signal, and identifies the position of the face 18 (see FIG. 5) in the image 17 (see FIG. 5) based on the facial features. In the image 17, since the background is included in addition to the face 18, it is necessary to identify the position of the face in the image based on the facial features such as the color of the facial skin or the shape of the facial organ. For facial skin color, the facial skin color and background in the image usually have different colors. Therefore, the position of the face in the image can be identified based on the difference in color. However, in order to reduce the influence of the light intensity on the image, first, an image acquired by the image acquisition device 12 is not easily affected by the light intensity from the RGB (Red, Green, Blue) color space, or NCC (Normalized Television Standards Committee) or It is necessary to convert to HSL (Hue, Saturation, Luminance) color space. Further, since the color of the skin of the face has a characteristic that the chromaticity distribution is concentrated, the area where the chromaticity distribution in the image is concentrated after conversion is the position of the face in the image.

  Subsequently, in step S203, the control module 13 generates a coordinate information signal based on the position of the face, generates a control signal, and the control signal is opposed to the coordinate image. Since the color of facial organs such as eyes, eyebrows and lips and the skin color of the face are usually different colors, the position of the facial organ can be substantially specified, and the face center point 17a can be determined by the position of the facial organ. The position of the face center point 17a is approximately at the nose. In addition, the control module 13 can calculate a coordinate information signal of the face center point 17a and generate a control signal, and the control signal is relative to the coordinate information signal. Finally, in step S204, the driving device 14 receives the control signal, is driven, and rotates the screen based on the coordinate information signal so that the screen 11 faces the face.

  FIG. 5 is an explanatory view of displacement of the first embodiment of the automatic rotation display device having the head image identification function of the present invention. 1 to 5, the control module 13 generates a coordinate information signal based on the face position according to the control flow step of FIG. 4, and the coordinate information signal includes the face center point 17 a, and the control module 13 Further acquires the coordinate information signal of the shooting center point of the image acquisition device 12, and the shooting center point of the image acquisition device 12 is the image center point 18 a of the image 18. When the control module 13 corresponds to the coordinate information signal in the image 18 of the face 17 and rotates the screen 11, the control module 13 controls the rotation of the screen 11 of the driving device 14 in the arrow direction 19 as shown in FIG. Then, the photographing center point (that is, the image center point 18 a) of the image acquisition device 12 is moved toward the face center point 17 a of the face 17.

  FIG. 6 is a functional block diagram of a second embodiment of the automatic rotation display device having a head image identification function of the present invention. Referring to FIG. 6, the difference between display device 20 and display device 10 shown in FIG. 1 is that speaker module 15 is further included. When the control module 13 outputs a control signal to the driving device 14 and controls the rotation of the screen 11 of the driving device 14, another control signal is simultaneously output to the speaker module 15 to control the sound transmission of the speaker module 15. For example, it is a beep sound and expresses that the screen 11 is rotated by sound. The speaker module 15 is a buzzer, a built-in speaker, or a built-in microphone.

  FIG. 7 is a functional block diagram of a third embodiment of an automatic rotation display device having an image identification function of the present invention. Referring to FIG. 7, the difference between the display device 30 and the display device 10 shown in FIG. 1 is that it further includes a light emitting module 16. When the control module 13 outputs a control signal to the driving device 14 and controls the rotation of the screen 11 of the driving device 14, another control signal is simultaneously output to the light emitting module 16, and the light emission of the light emitting module 16 is controlled. For example, it is red light or green light, and expresses that the screen 11 is rotated by the light. The light emitting module 16 is a light emitting diode.

  As described above, the present invention provides a display device that can automatically face the face by the screen, the image acquisition device, the control module, and the driving device, and the screen automatically rotates by the sound emitted by the speaker module or the light emission of the light emitting module. Announce what to do.
