The image capturing module 110 is used to face an object (such as a user's face) Department) Perform image capture. The micro motor 120 is used to drive the image capturing module 110 to rotate. The infrared camera 130 is used to continuously sample the object (the user's face) and obtain a dynamic temperature distribution image including a temperature feature point. The processing unit 140 determines a motion parameter according to the displacement information (such as the moving direction and the distance) of the temperature feature points in the dynamic temperature distribution image obtained by the infrared camera 130 (for example, the direction of rotation required by the image capturing module 110) And the control unit 150 controls the micro motor 120 to drive the image capturing module 110 to rotate according to the motion parameter, thereby implementing an automatic image tracking function of the image capturing module 110.

It should be particularly noted that the infrared camera 130 uses a non-contact infrared temperature measurement principle to convert infrared rays emitted from the object to be measured into electrical signals, and then display different temperature distributions in various colors. The entire temperature distribution state is displayed as a visible image. In addition, since the highest temperature of the human body surface is generally located around the tip of the nose, the eye socket, etc. (the highest temperature point can be set as a temperature feature point), the infrared camera 130 is particularly suitable for detecting the user's face. The position of the part, and can effectively reflect the body temperature state of the measured human body. Moreover, the temperature measurement reaction speed of the infrared camera 130 is extremely fast (the temperature measurement is completed within 1 second), so that the object can be continuously temperature sampled to obtain a dynamic temperature distribution image.

2A, 2B are partial schematic views of an electronic device 10 in accordance with some different embodiments of the present invention.

Please refer to FIG. 2A. The electronic device 10 is, for example, a notebook computer, including an image capturing module 110, an infrared camera 130, a screen 160, a light sensor 180, and a light-emitting component 190 (in order to simplify the drawing and highlighting) Technology of the present invention Emphasis is placed only on the keyboard body portion of the notebook computer in FIG. 2A).

The image capturing module 110 has a first surface (toward the user) and a second surface (away from the user), and includes a charge coupled device (CCD) 112 disposed on the first surface. On S1. In addition, the image capturing module 110 is pivotally connected to the screen 160 by a first pivot 172, and the first pivot 172 is connected to a micro motor (for example, a stepping micro electric motor, not shown). The image capturing module 110 can be driven by the micro motor to rotate relative to the screen 160 about the first pivot 172 (swing back and forth). In addition, the light sensor 180 and the light-emitting element 190 are also disposed on the first surface S1 of the image capturing module 110, wherein the light sensor 180 is used to recognize the brightness of the environment, and the light-emitting element 190 (for example, the light-emitting device) The polar body (LED) can adjust its luminous intensity according to the sensing result of the photo sensor 180. It should be understood that the number and arrangement positions of the light-emitting elements 190 are not limited as shown in FIG. 2A, but may be adjusted according to actual needs.

Please refer to Figure 2B again. The difference between the electronic device 10 shown in FIG. 2B and the embodiment shown in FIG. 2A is that the image capturing module 110 is further connected to the screen 160 by a second pivot 174, wherein the second pivot 174 is substantially perpendicular to the first pivot 172, and the second pivot 174 is coupled to another micro motor (for example, a stepping micro electric motor, not shown), whereby the image capturing module 110 can be used by the aforementioned micro motor The drive is rotated about the first pivot 172 relative to the screen 160 (swinging back and forth) or/and rotating about the screen 160 about the second pivot 174 (swinging left and right). According to some embodiments of the present invention, the pivoting angle of the image capturing module 110 about the first pivot 172 relative to the screen 160 is between 180 degrees and -180 degrees, and the image capturing module 110 surrounds the second pivot. The pivot of the shaft 174 relative to the screen 160 The rotation angle is between 0 and 360 degrees.

Figure 4 is a flow chart showing automatic tracking of a user's face image in accordance with an embodiment of the present invention. First, in step S401, the user sits in front of the screen 160 of the notebook computer 10, and adjusts the CCD (not shown) of the image capturing module 110 to face the face, and then turns on the application of the image capturing module 110. The program causes the CCD of the image capture module 110 to begin image capture (eg, video mode) on the user's face.

Next, in step S402, the user turns on the application of the infrared camera (not shown), so that the infrared camera starts to continuously sample the user's face. At this stage, the infrared camera can capture an instant/dynamic temperature distribution image of the user's face (consisting of images of multiple temperature distribution states), wherein the images of these temperature distribution states can be stored by the notebook computer 10. The unit is stored, and the processing unit (not shown) of the notebook computer 10 can determine a temperature feature point based on the images. For example, the temperature around the tip of the user's face in the image may be about 36 degrees or higher, and the rest of the face around the tip of the nose and the temperature of the environment are less than 36 degrees, so the processing unit can The highest temperature position in the image (around the tip of the nose of the user's face) is set as a temperature feature point.

According to some embodiments of the present invention, the application of the image capturing module 110 and the infrared camera can be integrated so that the two can simultaneously perform image capturing and temperature sampling on the user's face.

In this way, an electronic device with automatic image tracking function can be realized without manually adjusting the angle of the screen and the CCD.

According to some embodiments of the present invention, the position of the object (for example, the user's face), that is, the position of the temperature feature point in the temperature distribution image, may be first sensed by the infrared camera, and then the temperature characteristic is obtained through the processing unit analysis. The point moves to the center of the image (displacement information) image capturing module 110 to rotate the direction and angle (motion parameter), and then the control unit controls at least one micro motor (not shown) to drive the image according to the motion parameter. The capture module 110 rotates relative to the screen 160 to automatically track and align the user's face, and finally activates the CCD of the image capture module 110 to perform image capture on the user's face.
